IELTS grammar. Lesson 12: Modal verbs
Verbs can, could, may, might, will, would, must, shall, should, ought to are called modal verbs.
They are different from normal verbs:
1. We do not add 's' to them in yhe third person singular. (She can do it. He might join us today)
2. We make questions with them by using inversion. (He could do there. Could he go there?)
3. Modal verbs are always followed by the infinitive of another verb without 'to'.
Modal verbs can be used to:
a) Talk about something we're sure/unsure of. (It can't be this expensive! It must be very cold outside today)
b) Talk about our abilities or skills. (I can't swim. She can play basketball very well)
c) Give advice or say if something is necessary/unnecessary. (We must eat healthy food. He should stop smoking)
d) Ask for the permission. (May I borrow your pen, please?)
e) Talk about habits or thing we ususally do/did. (When we were kids, we would always play football during summer)
