Grammar and Sentence Structure Practice Test 7 Flashcards

Which sentence is grammatically correct?

Answer: She doesn't like to eat vegetables.

With a third-person singular subject ('she'), the auxiliary verb 'does' is used to form the negative, and the main verb stays in its base form: 'doesn't like.'

Fill in the blank: 'My brother _____ to the store every Saturday morning.'

Answer: goes

The subject 'My brother' is third-person singular, so the simple present verb must take the -s ending: 'goes.'

Which sentence uses the correct future tense?

Answer: We will go to the concert next week.

The simple future is formed with 'will' followed by the base form of the verb: 'will go.' Adding '-ing' or omitting 'will' creates an error.

Choose the correct word to complete the sentence: 'She has been waiting _____ two hours.'

Answer: for

'For' is used with a duration or period of time (e.g., two hours, three days). 'Since' is used with a specific point in time (e.g., since Monday).

Which sentence is written in the correct passive voice?

Answer: The letter was written by Maria.

Passive voice is formed with 'was/were' + the past participle. The past participle of 'write' is 'written,' not 'wrote' (which is simple past active).

Choose the sentence that correctly uses a conjunction to join two independent clauses.

Answer: She studied hard, but she failed the exam.

When two independent clauses are joined by a coordinating conjunction like 'but,' a comma is placed before the conjunction — not after it or in any other position.
