Conditional Structures Flashcards

Choose the correct mixed conditional: 'If she _____ harder when she was young, she _____ successful now.'

Answer: had studied / would be

Mixed conditionals combine a past unreal condition (had studied) with a present result (would be).

Which sentence uses the zero conditional correctly?

Answer: If you freeze water, it turns to ice.

The zero conditional uses simple present in both clauses to express universal truths.

Select the correct inverted conditional form: '_____ any problems arise, please contact support immediately.'

Answer: Should

'Should any problems arise' is a formal inversion of 'If any problems should arise.'

What does 'Unless you leave now, you'll miss the train' mean?

Answer: If you don't leave now, you'll miss the train.

'Unless' means 'if not,' so 'unless you leave' = 'if you don't leave.'

Complete the third conditional: 'They _____ the game if their best player _____ injured.'

Answer: would have won / hadn't been

Third conditionals use 'would have + past participle' and 'hadn't + past participle' for past unreal situations.

Which sentence expresses a wish about the present using a conditional structure?

Answer: I wish I knew the answer.

'I wish I knew' uses past simple to express an unreal present wish, mirroring second conditional structure.

Identify the error: 'If I would have more time, I would exercise every day.'

Answer: 'would have' should be 'had'

In second conditionals, the if-clause uses past simple ('had'), not 'would have.'
