Gaokao - National College Entrance Exam — Questions and Answers
Question 1: Read the passage and answer the question. Passage: Sleep deprivation is a growing problem in modern society. Research shows that consistently sleeping fewer than seven hours per night is linked to increased risks of obesity, heart disease, and cognitive impairment. Despite this evidence, many people sacrifice sleep in favor of work or entertainment. Health experts argue that viewing sleep as a luxury rather than a necessity is a dangerous attitude. According to the passage, why do health experts find the current attitude toward sleep 'dangerous'?
- Because people who sleep less tend to work less productively.
- Because entertainment options keep people from sleeping.
- Because sleeping too much can also be harmful.
- Because treating sleep as optional ignores serious health risks. (Correct answer)
Correct answer: Because treating sleep as optional ignores serious health risks.
Experts warn against viewing sleep as a luxury because doing so ignores documented links to obesity, heart disease, and cognitive impairment.
Question 2: The Chinese proverb '一石激起千层浪' (one stone creates a thousand ripples) is most appropriately used in an essay about life-changing impact to illustrate:
- The value of perseverance
- How a single pivotal event can trigger a cascade of far-reaching changes in one's life (Correct answer)
- The importance of gradual, steady effort
- The unpredictability of natural phenomena
Correct answer: How a single pivotal event can trigger a cascade of far-reaching changes in one's life
The proverb describes how throwing one stone into still water creates expanding ripples — metaphorically, one key moment or decision can set off ripple effects that transform many aspects of life.
Question 3: The chord of contact of point P(2, 1) with respect to the circle x² + y² = 5 has equation:
- 2x - y = 5
- x + 2y = 5
- x - 2y = 5
- 2x + y = 5 (Correct answer)
Correct answer: 2x + y = 5
The chord of contact from external point (x₀, y₀) to circle x² + y² = r² is xx₀ + yy₀ = r². So: 2x + y = 5.
Question 4: A sphere is inscribed in a regular tetrahedron with edge length a. Which formula gives the radius of the inscribed sphere?
- r = a√3/6
- r = a√6/12 (Correct answer)
- r = a/4
- r = a/2
Correct answer: r = a√6/12
For a regular tetrahedron with edge a, the inradius r = a/(2√6) = a√6/12.
Question 5: In the Chinese classic 'Dream of the Red Chamber' (红楼梦), the life-altering impact of which factor drives the Jia family's tragic decline?
- A single military defeat
- A natural disaster
- A foreign invasion
- The combined weight of political downfall, moral corruption, and the transience of worldly prosperity (荣辱兴衰) (Correct answer)
Correct answer: The combined weight of political downfall, moral corruption, and the transience of worldly prosperity (荣辱兴衰)
The Jia family's decline in 'Dream of the Red Chamber' results from the accumulation of political disfavor, internal moral decay, and the Buddhist-Taoist theme of all worldly glory being impermanent (盛极必衰).
Question 6: If a Gaokao applicant's score meets a university's general 投档线 but falls short of their chosen major's internal cutoff, and they checked '服从专业调剂' (willing to accept major reallocation) on their application, what is the most likely outcome?
- The university may enroll them in a different major that still has available spots (Correct answer)
- Their application is frozen until a student in their preferred major voluntarily withdraws
- They are guaranteed entry but receive reduced scholarship eligibility for the unwanted placement
- They are immediately 退档 (file withdrawn) and must participate in 征集志愿 rounds
Correct answer: The university may enroll them in a different major that still has available spots
Checking '服从专业调剂' gives the university permission to place the student in any other major with remaining capacity, rather than rejecting them outright. Students who do NOT check this box and whose score is insufficient for their stated major face 退档 (file withdrawal), which can be a serious setback if no better 征集志愿 options remain in that batch.
Question 7: The Long March (长征, 1934-1935) was undertaken by the Chinese Red Army primarily to:
- Launch a surprise counteroffensive against Japanese forces occupying Manchuria
- Establish direct contact with Soviet military advisors along the northern border
- Escape Nationalist encirclement campaigns and relocate to a new revolutionary base in the northwest (Correct answer)
- Negotiate a ceasefire agreement with Chiang Kai-shek's Nationalist government
Correct answer: Escape Nationalist encirclement campaigns and relocate to a new revolutionary base in the northwest
The Long March was a strategic military retreat to escape the Nationalist 'encirclement and suppression campaigns' (围剿). The Red Army traveled roughly 9,000 km from Jiangxi Province to Yan'an in Shaanxi, where it rebuilt as a revolutionary base — a survival that proved decisive for the CCP's future.
Question 8: Which literary device involves opening a Gaokao essay with a famous quotation to establish authority and context?
- 排比法 (parallel structure)
- 抑扬法 (contrasting approach)
- 设问法 (rhetorical question opening)
- 引用开头法 (opening with a quotation) (Correct answer)
Correct answer: 引用开头法 (opening with a quotation)
'引用开头法' means opening the essay with a famous quotation (from classical texts, famous people, or proverbs), immediately establishing credibility and connecting to the topic.
Question 9: A Gaokao essay prompt shows an image of a person at a crossroads. What type of prompt is this?
- 话题作文 (topic essay)
- 续写作文 (continuation essay)
- 图画材料作文 (picture-based material essay) (Correct answer)
- 命题作文 (titled essay)
Correct answer: 图画材料作文 (picture-based material essay)
'图画材料作文' uses a visual image as the prompt. Students interpret the symbolic meaning of the image (e.g., crossroads = life choices) and write an argumentative essay based on their interpretation.
Question 10: A 5 kg box is pushed across a horizontal floor by a 30 N horizontal force. The coefficient of kinetic friction between the box and floor is 0.4. What is the acceleration of the box? (g = 10 m/s²)
- 2 m/s² (Correct answer)
- 6 m/s²
- 4 m/s²
- 1 m/s²
Correct answer: 2 m/s²
Normal force N = mg = 5 × 10 = 50 N. Friction force f = μN = 0.4 × 50 = 20 N. Net force = 30 − 20 = 10 N. By Newton's Second Law, a = F_net / m = 10 / 5 = 2 m/s².
Question 11: The Xinhai Revolution (辛亥革命) of 1911 most directly resulted in:
- The unification of China under the warlord Yuan Shikai as constitutional emperor
- Japan's annexation of Taiwan and the Liaodong Peninsula
- The establishment of the People's Republic of China under Mao Zedong
- The abdication of Emperor Puyi and the founding of the Republic of China (Correct answer)
Correct answer: The abdication of Emperor Puyi and the founding of the Republic of China
The Xinhai Revolution, organized by Sun Yat-sen's Revolutionary Alliance (同盟会), overthrew the Qing dynasty. Emperor Puyi abdicated in February 1912, ending over 2,000 years of imperial rule and establishing the Republic of China with Sun Yat-sen as its provisional president.
Question 12: In the light-harvesting complex of chloroplasts, energy from absorbed photons is transferred to the reaction center by:
- Proton gradient across thylakoid membrane
- ATP hydrolysis
- Electron transport chain proteins
- Resonance energy transfer between pigment molecules (Correct answer)
Correct answer: Resonance energy transfer between pigment molecules
Excited electrons in antenna pigment molecules transfer energy via resonance (Förster energy transfer) through successive pigment molecules to the reaction center chlorophyll.
Question 13: Which agricultural system is most common in densely populated parts of East and Southeast Asia?
- Extensive commercial grain farming
- Nomadic pastoralism
- Plantation agriculture for export crops
- Intensive subsistence wet rice cultivation (Correct answer)
Correct answer: Intensive subsistence wet rice cultivation
Intensive subsistence wet rice (paddy) cultivation dominates because rice yields high calories per unit area, supporting high population densities; it requires heavy labor input on small plots.
Question 14: Read the passage and answer the question. Passage: Overfishing is depleting marine ecosystems at an alarming rate. When fish populations are reduced faster than they can reproduce, stocks collapse — sometimes permanently. The collapse of the Grand Banks cod fishery off Canada in the 1990s left tens of thousands of fishermen without work and has not recovered to this day. International agreements on fishing quotas exist, but enforcement is difficult on the open seas. What lesson does the Grand Banks example illustrate?
- Canadian fishermen were the main cause of global overfishing.
- Cod is the most commercially valuable fish in the world.
- International fishing agreements are highly effective at protecting fish stocks.
- Overfishing can permanently destroy fish populations and the communities dependent on them. (Correct answer)
Correct answer: Overfishing can permanently destroy fish populations and the communities dependent on them.
The Grand Banks collapse illustrates that overfishing can permanently destroy stocks and devastate dependent communities.
Question 15: In Chinese high school composition topics about life-changing experiences, which literary technique involves starting with a present moment and then flashing back to explain how the protagonist arrived there?
- 插叙 (intercalated narration)
- 顺叙 (chronological narration)
- 补叙 (supplementary narration)
- 倒叙 (reverse chronological narration / flashback) (Correct answer)
Correct answer: 倒叙 (reverse chronological narration / flashback)
'倒叙' means beginning with the ending or a present moment and then narrating past events that explain the current situation — the classic flashback structure.
Question 16: In which stage of aerobic respiration is CO₂ directly released as a product?
- Glycolysis
- Oxidative phosphorylation
- Both glycolysis and oxidative phosphorylation
- Pyruvate oxidation and Krebs cycle (Correct answer)
Correct answer: Pyruvate oxidation and Krebs cycle
CO₂ is released during pyruvate oxidation (pyruvate → acetyl-CoA + CO₂) and during the Krebs cycle (at isocitrate dehydrogenase and α-ketoglutarate dehydrogenase reactions).
Question 17: The unit of magnetic flux is:
- Tesla (T)
- Weber (Wb) (Correct answer)
- Henry (H)
- Farad (F)
Correct answer: Weber (Wb)
Magnetic flux Φ = BA is measured in Webers (Wb); 1 Wb = 1 T·m².
Question 18: ATP synthase in the mitochondria produces ATP using energy derived from:
- The proton gradient across the inner mitochondrial membrane (Correct answer)
- Reduction of FAD to FADH₂
- Direct transfer of phosphate groups from NADH
- Substrate-level phosphorylation in the matrix
Correct answer: The proton gradient across the inner mitochondrial membrane
H⁺ ions flow down their electrochemical gradient through ATP synthase (Complex V) from the intermembrane space to the matrix, driving ATP synthesis via chemiosmosis.
Question 19: Darwin's theory of natural selection is best described as:
- Individuals with favorable traits survive and reproduce more successfully (Correct answer)
- All members of a species evolve simultaneously
- Evolution occurs through random genetic mutations only
- Organisms acquire traits by use or disuse during their lifetime
Correct answer: Individuals with favorable traits survive and reproduce more successfully
Natural selection states that heritable traits increasing survival and reproduction become more common over generations.
Question 20: Which of the following is a characteristic feature distinguishing prokaryotic cells from eukaryotic cells?
- Cell membrane made of phospholipids
- Absence of membrane-bound nucleus (Correct answer)
- Ability to carry out cellular respiration
- Presence of ribosomes
Correct answer: Absence of membrane-bound nucleus
Prokaryotic cells lack a membrane-bound nucleus; their genetic material exists as a nucleoid region in the cytoplasm.
Question 21: Which measure of central tendency is most affected by an extreme outlier in a dataset?
- Mean (Correct answer)
- Mode
- Range
- Median
Correct answer: Mean
The mean incorporates every value arithmetically, so a single extreme outlier can shift it significantly.
Question 22: In a circuit, a 12 V battery with internal resistance 1 Ω is connected to an external resistance of 5 Ω. The terminal voltage of the battery is:
- 6 V
- 8 V
- 10 V (Correct answer)
- 12 V
Correct answer: 10 V
I = 12/(5+1) = 2 A; terminal voltage = 12 − 2×1 = 10 V.
Question 23: A train moving at 72 km/h applies its brakes and decelerates uniformly to rest in 10 seconds. What distance does the train cover while braking?
- 100 m (Correct answer)
- 50 m
- 72 m
- 200 m
Correct answer: 100 m
Convert speed: 72 km/h = 20 m/s. Using s = (u + v)/2 × t = (20 + 0)/2 × 10 = 100 m. Alternatively, find deceleration a = (0 − 20)/10 = −2 m/s², then s = ut + ½at² = 20(10) + ½(−2)(100) = 200 − 100 = 100 m.
Question 24: The literary device '互文' (hùwén), frequently found in classical Chinese poetry, refers to:
- Repeating a phrase verbatim for emphasis
- Inverting the subject and predicate for poetic effect
- Using a historical allusion to explain a current situation
- Two parallel phrases whose meanings must be read together and merged for full understanding (Correct answer)
Correct answer: Two parallel phrases whose meanings must be read together and merged for full understanding
'互文' is a classical rhetorical device where two parallel phrases are semantically intertwined, meaning each phrase implicitly contains the meaning of the other. For example, in '秦时明月汉时关', 'Qin-time bright moon and Han-time pass' actually means 'the bright moon and the pass of both the Qin and Han times.'
Question 25: A regular triangular prism has base edge length 4 and height 6. What is its total surface area?
- 48 + 4√3
- 72 + 4√3
- 72 + 8√3 (Correct answer)
- 48 + 8√3
Correct answer: 72 + 8√3
Two equilateral triangle bases: 2 × (√3/4 × 4²) = 8√3. Three rectangular lateral faces: 3 × (4 × 6) = 72. Total = 72 + 8√3.
Question 26: Meanders in a river form as a result of:
- Differential erosion on outer bends and deposition on inner bends due to secondary circulation (Correct answer)
- Tectonic faulting that curves river channels
- Uniform high-velocity flow eroding a straight channel
- Glacial outwash deposits creating sinuous landforms
Correct answer: Differential erosion on outer bends and deposition on inner bends due to secondary circulation
Helical (corkscrew) flow in river channels causes erosion on the outer (concave) bank forming a river cliff, while reduced velocity deposits sediment on the inner (convex) bank as a point bar.
Question 27: The solubility product Ksp of AgCl is 1.8×10⁻¹⁰. The molar solubility of AgCl in pure water is:
- 9.0×10⁻¹¹ M
- 1.34×10⁻⁵ M (Correct answer)
- 1.8×10⁻¹⁰ M
- 3.6×10⁻¹⁰ M
Correct answer: 1.34×10⁻⁵ M
AgCl → Ag⁺ + Cl⁻; if s = molar solubility, then Ksp = s² → s = √(1.8×10⁻¹⁰) ≈ 1.34×10⁻⁵ M.
Question 28: What role does the Gaokao score play in university admissions in China?
- It has no impact on admissions; extracurricular activities are more important.
- It determines eligibility for specific universities. (Correct answer)
- It allows students to bypass interviews and focus solely on exam performance. (Correct answer)
- It is optional for students applying to domestic universities.
Correct answer: It determines eligibility for specific universities.
University cut-off scores for the Gaokao are not standardized nationwide; instead, they vary significantly by province. These scores are determined annually based on factors such as the overall difficulty of that year's exam, the number of students taking the test, and the performance distribution of students within each specific province, ensuring a localized and dynamic admissions process.
Question 29: Which graph is most appropriate for displaying the distribution of a continuous variable such as exam scores?
- Histogram (Correct answer)
- Bar chart
- Pie chart
- Scatter plot
Correct answer: Histogram
Histograms group continuous data into intervals (bins) and display frequency distributions effectively.
Question 30: Read the passage and answer the question. Passage: The Great Wall of China is one of the most iconic structures in human history. Construction began as early as the 7th century BC, though the most recognizable sections were built during the Ming Dynasty (1368–1644). The wall stretches thousands of kilometers and was primarily built to protect Chinese states from northern nomadic invasions. Popular belief holds that the Great Wall is visible from space, but this claim has been debunked — the wall is too narrow to be seen with the naked eye from orbit. What misconception does the passage correct?
- That the Great Wall was built to protect against southern invaders.
- That the Great Wall was built entirely during the Ming Dynasty.
- That the Great Wall is visible from space with the naked eye. (Correct answer)
- That the Great Wall is the longest structure ever built.
Correct answer: That the Great Wall is visible from space with the naked eye.
The passage explicitly identifies the space-visibility claim as a myth that has been 'debunked.'
Question 31: A bag contains 3 red balls and 5 blue balls. If one ball is drawn at random, what is the probability of drawing a red ball?
- 1/4
- 5/8
- 3/5
- 3/8 (Correct answer)
Correct answer: 3/8
There are 3 red balls out of 8 total, so the probability is 3/8.
Question 32: If the eccentricity of an ellipse is 1/2, and one semi-axis is a = 4, what is the length of the other semi-axis b?
- 2√3 (Correct answer)
- 3
- √15
- 2
Correct answer: 2√3
Eccentricity e = c/a = 1/2, so c = 2. Then b² = a² - c² = 16 - 4 = 12, giving b = 2√3.
Question 33: At 25°C, for the reaction H₂(g) + I₂(g) ⇌ 2HI(g), K = 50. If [H₂] = [I₂] = 0.1 M and [HI] = 0.5 M initially, the reaction quotient Q is:
- 50
- 5
- 100
- 25 (Correct answer)
Correct answer: 25
Q = [HI]²/([H₂][I₂]) = 0.25/(0.1 × 0.1) = 25. Since Q < K, the reaction proceeds forward.
Question 34: Which type of plate boundary produces the deepest ocean trenches and most explosive volcanic eruptions?
- Conservative (transform) boundary
- Constructive (divergent) boundary
- Destructive (convergent/subduction) boundary (Correct answer)
- Collision boundary between two continental plates
Correct answer: Destructive (convergent/subduction) boundary
At destructive boundaries, the denser oceanic plate subducts beneath a continental or oceanic plate, forming deep trenches (e.g., Mariana Trench) and explosive arc volcanoes due to water-rich melting.
Question 35: The Nanjing Massacre (南京大屠杀, 1937-1938) occurred during:
- The Chinese Civil War
- The Boxer Rebellion
- The Japanese occupation of Nanjing following the fall of the Chinese capital during the Second Sino-Japanese War (Correct answer)
- The First Sino-Japanese War (1894-1895)
Correct answer: The Japanese occupation of Nanjing following the fall of the Chinese capital during the Second Sino-Japanese War
After capturing Nanjing (then China's capital) in December 1937 during the Second Sino-Japanese War, Japanese forces killed an estimated 200,000-300,000 Chinese civilians and prisoners of war over six weeks.
Question 36: For the reaction PCl₅(g) ⇌ PCl₃(g) + Cl₂(g), which change increases the equilibrium yield of PCl₃?
- Adding more PCl₃
- Decreasing temperature (if exothermic)
- Adding an inert gas at constant volume
- Decreasing pressure (Correct answer)
Correct answer: Decreasing pressure
The forward reaction increases moles of gas (1 → 2); decreasing pressure shifts equilibrium to the side with more moles of gas, increasing PCl₃ yield.
Question 37: For a first-order reaction, the half-life t₁/₂ is related to the rate constant k by:
- t₁/₂ = ln 2 / k (Correct answer)
- t₁/₂ = 1/k
- t₁/₂ = k/ln 2
- t₁/₂ = 2/k
Correct answer: t₁/₂ = ln 2 / k
For a first-order reaction: [A] = [A₀]e^(−kt); at t₁/₂, [A] = [A₀]/2, giving t₁/₂ = ln 2 / k ≈ 0.693/k.
Question 38: The First United Front (第一次国共合作, 1923-1927) was an alliance between:
- The CPC and warlord armies
- The KMT and Japan
- The CPC and the Soviet Union
- The Chinese Communist Party (CPC) and the Nationalist Party (KMT/Guomindang) (Correct answer)
Correct answer: The Chinese Communist Party (CPC) and the Nationalist Party (KMT/Guomindang)
The First United Front was a coalition between the CPC and the KMT under Sun Yat-sen, formed to fight northern warlords. It broke down in 1927 with Chiang Kai-shek's Shanghai Massacre.
Question 39: In the context of Gaokao essay evaluation, what does '偏题' (piāntí) mean, and what are its consequences?
- Making grammatical errors
- Using an unusual writing style
- Exceeding the word limit
- Writing off-topic or misinterpreting the prompt's central theme, resulting in significant grade deduction (Correct answer)
Correct answer: Writing off-topic or misinterpreting the prompt's central theme, resulting in significant grade deduction
'偏题' means straying from the prompt's intended topic or misunderstanding the central theme. It is one of the most penalized errors in Gaokao essay grading, as it indicates the student failed to understand the prompt.
Question 40: Choose the word that best completes this cloze sentence: 'The charity organization _____ thousands of meals to families affected by the natural disaster.'
- purchased
- distributed (Correct answer)
- wasted
- consumed
Correct answer: distributed
'Distributed' means to give out or deliver items to a number of people, which perfectly describes a charity providing meals to affected families. The other options do not reflect charitable action toward others.
Question 41: The equation of a circle is x² + y² - 6x + 8y - 11 = 0. What is the radius of this circle?
- 6 (Correct answer)
- √56
- √11
- 6√2
Correct answer: 6
Rewrite in standard form by completing the square: (x-3)² + (y+4)² = 9 + 16 + 11 = 36. The radius is √36 = 6.
Question 42: The skin effect in AC conductors refers to:
- Increase of resistance at low temperatures
- Current concentration near the conductor surface at high frequencies (Correct answer)
- Uniform current distribution at all frequencies
- Corrosion of the outer layer
Correct answer: Current concentration near the conductor surface at high frequencies
At high frequencies, electromagnetic effects cause current to concentrate in a thin surface layer (skin depth decreases with frequency), increasing effective resistance.
Question 43: The May Fourth Movement of 1919 was a direct response to:
- The founding of the Communist Party of China.
- The Japanese invasion of Manchuria in 1931.
- The outbreak of the Northern Expedition.
- The outcome of the Paris Peace Conference regarding the Shandong issue. (Correct answer)
Correct answer: The outcome of the Paris Peace Conference regarding the Shandong issue.
The movement was ignited by student protests against the decision at the Paris Peace Conference to transfer former German concessions in Shandong to Japan, rather than returning them to China. This was seen as a betrayal by the Allied powers and exposed the weakness of the Beiyang government, sparking a nationwide movement of nationalism and intellectual change.
Question 44: Read the passage and answer the question. Passage: Ocean plastic pollution is a worsening global crisis. Each year, an estimated 8 million metric tons of plastic enter the ocean. Larger plastic objects break down into tiny particles called microplastics, which have been found in fish, sea birds, drinking water, and even human blood. While much attention focuses on plastic bags and bottles, fibers shed from synthetic clothing during washing also contribute significantly to ocean microplastic pollution. What is a less obvious source of ocean microplastics mentioned in the passage?
- Industrial chemical runoff entering rivers.
- Plastic bags discarded near coastlines.
- Plastic bottles left on beaches by tourists.
- Fibers shed from synthetic clothing during washing. (Correct answer)
Correct answer: Fibers shed from synthetic clothing during washing.
The passage notes that while plastic bags and bottles get the most attention, synthetic clothing fibers are also a significant, less recognized source.
Question 45: Benzene reacts with bromine in the presence of FeBr₃ catalyst. What type of reaction occurs?
- Free radical substitution
- Addition reaction
- Nucleophilic substitution
- Electrophilic substitution (Correct answer)
Correct answer: Electrophilic substitution
Benzene undergoes electrophilic aromatic substitution (EAS) with Br₂/FeBr₃. FeBr₃ activates Br₂ to form the electrophile Br⁺.
Question 46: Read the passage and answer the question. Passage: Social media platforms were designed to connect people, but research increasingly suggests they may also drive social division. Algorithms prioritize content that provokes strong emotional reactions — often outrage — because such content keeps users engaged longer. As a result, users are frequently exposed to extreme viewpoints, which can reinforce existing beliefs and deepen polarization between groups. According to the passage, why do social media algorithms favor emotionally provocative content?
- Because it keeps users on the platform longer. (Correct answer)
- Because it is more truthful than neutral content.
- Because users have specifically requested more emotional content.
- Because it helps reduce political polarization.
Correct answer: Because it keeps users on the platform longer.
The passage states algorithms prioritize provocative content because it keeps users engaged longer — a direct causal relationship.
Question 47: Which international universities accept Gaokao scores for admission?
- University of Toronto (Canada) (Correct answer)
- University of Sydney (Australia) (Correct answer)
- Massachusetts Institute of Technology (U.S.)
- University of Cambridge (U.K.)
Correct answer: University of Toronto (Canada)
The University of Sydney in Australia is one prominent international institution that accepts Gaokao scores for admission, recognizing the exam's rigor and the academic caliber of Chinese students. This trend is growing, with several universities in countries like Australia, Canada, and the UK now considering Gaokao results. This simplifies the application process for Chinese students seeking higher education abroad.
Question 48: Which of the following is the equation of a hyperbola with real axis along the y-axis?
- x²/9 - y²/4 = 1
- y²/9 + x²/4 = 1
- x²/4 + y²/9 = 1
- y²/9 - x²/4 = 1 (Correct answer)
Correct answer: y²/9 - x²/4 = 1
A hyperbola with real axis along the y-axis has the form y²/a² - x²/b² = 1. Option A matches this form.
Question 49: In a regular tetrahedron with an edge length of 3, what is the distance from any vertex to the opposite face?
- √3
- √6 (Correct answer)
- 2√2
- 3√2/2
Correct answer: √6
The distance from a vertex to the opposite face is the height (H) of the regular tetrahedron. The formula for the height is H = a√(2/3) = a√6/3, where 'a' is the edge length. For a=3, the height is H = 3√6/3 = √6.
Question 50: The 2023 Gaokao National Paper I essay prompt involved 'good with technology' (技术好的人). What type of essay prompt structure is this?
- Material-based argumentative essay (材料作文) (Correct answer)
- Comparative essay
- Personal narrative (记叙文)
- Descriptive essay about technology
Correct answer: Material-based argumentative essay (材料作文)
Modern Gaokao essay prompts are almost exclusively '材料作文' (material-based): the student is given a text/scenario and must write an argumentative essay based on it, rather than freely chosen topics.
