English Tenses Exercises with Explained Answers

Published · Updated · 3 min read

A timeline marks past, present and future events.

Choose a tense by asking two questions: when is the situation, and how does the speaker view it — as a habit, an action in progress, or something connected to a later point. Time words help, but the whole context decides the answer.

I have lost my keys, so I can’t open the door.

💡 The past loss matters now, so the present perfect fits.

I lost my keys yesterday, but I found them later.

💡 Yesterday is a finished past time, so the past simple fits.

Water boils at 100°C at sea level.

💡 A general fact uses the present simple.

Common mistakes to watch

❌ I have seen her yesterday.

✅ I saw her yesterday.

In standard English, a finished past time phrase normally takes the past simple.

❌ I am knowing the answer.

✅ I know the answer.

Know usually describes a state, so it rarely takes a continuous form.

❌ He work in a bank.

✅ He works in a bank.

A third-person singular subject takes -s in the present simple.

Can one sentence have more than one correct tense?

Yes. Different tenses can be grammatical with different meanings. That is why each question above gives context to fix the intended meaning.

Is the present perfect used the same way everywhere?

Not exactly. American English sometimes uses the past simple with already, just and yet where British English prefers the present perfect. Both are understood.
