Modal verbs are a special group of auxiliary verbs. They don’t express facts, we use them before other verbs to
express attitudes, opinions and judgements of events:permission, ability, possibility, request, obligation ...
1) Correct the following sentences.
- She cans play the piano.
- You don’t must open the book.
- Can you to sing?
- Last year I must work on Saturdays.
- My sister couldn’t her homework.
- I would like to can play the violin.
They are different from most other verbs in four ways:
1. They are always followed by an infinitive without “to”: * I may go out tonight.
2. They have no – s on the third person singular: * John should study harder.
3. They don‟t need auxiliary in negatives and questions: * Can you help me? – No, I can’t
4. They don‟t have tenses, infinitives or participles : * Being able to speak English is very useful nowadays.
