  2. Modals Verbs that can come before another verb and add to the meaning of that verb. He plays the guitar. He can play the guitar. See that film. You should see that film.
  3. The modals are: WILL / WOULD CAN / COULD MAY / MIGHT SHALL / SHOULD OUGHT TO MUST HAVE TO NEED
  4. The rules about using modals: A modal always has the same form. I must leave. He must leave. A modal is followed by the infinitive. I shouldknow the answer but I don’t. Questions are formed by inverting the modal and the subject. Hecan swim well. – Canhe swim well? Negatives are formed by adding not (n’t). He couldn’t come with us because he was busy.
  5. Exceptions Have to and need take –s in the 3rd person singular: He has to go. Your hair needsto be cut. (passive full infinitive) Your hair needscutting. (-ing form)
  6. Exceptions Modal verbs are followed by an infinitive without to, except for ought to and have to. Sorry, I can’tcome. He mighthave phoned you when you were out. I haveto meet Sally. You oughtto see the performance.
  7. Modal verbs are used to express: Ability (in the present / future) Can / be able to Paul can swim fast. I can give you back the money next week. (usual) I will be able to give you back the money next week. (less usual, more formal)
  8. Modal verbs are used to express: Ability (in the past) Could – for repeated actions and with the verbs see, hear, smell, understand etc. for single actions She could play the violin when she was six. (repeated action) I could smell something burning. (single action) Was able to – for either repeated or single actions She was able to play the violin when she was six. I was able to go on a trip round the city last week. (single action)
  9. Modal verbs are used to express: Could / be able to can both be used in negations and questions for either repeated or single actions. She couldn’t / wasn’t able to pass her driving test. Were you able to / Could you get to work yesterday?
  10. Can is the Present Simple, could is the Past Simple. For other tenses we use be able to. He hasn’t been able to call them yet but he can call them tomorrow.
  11. Modal verbs are used to express: Possibility (present or future) May / might / could + present infinitive Jim may / might / could pass the test this time. Where’s Ann? – She couldbe in the shopping mall. Possibility (past) May / might / could + perfect infinitive John looks miserable. He may/might/couldhave lost his job.
  12. Modal verbs are used to express: Could + perfect infinitive is also used for something which was possible but did not actually happen. Don’t drive that fast! You could have killed that boy. (Luckily, you didn’t kill him.) To express possibility in questions we don’t use may. We use: Can he? Could he? Is he likely to? Might he?
  13. Modal verbs are used to express: Probability Ought to / should + present infinitive (something is probable now or in the future) Laura ought to / should passthe exam. (= She will probably pass it.) Ought to / should + perfect infinitive (something that we expected to happen but we don’t know if it happened or not) Has Sue phoned yet?

  14. Modal verbs are used to express: Logical assumptions Can’t / couldn’t + present infinitive (= I don’t think; It’s logically improbable) She can’t berich. Her house is too small. Must + present infinitive (= I think; I’m fairly sure; It’s logically probable) His face is red. He must beangry. Can’t is the opposite of must.
