1. As complementary verbs that are,
modal verbs do not work without
another verb. This is another verb
always after the modal verb and is in
the base form (the infinitive without
"to"). Modal verbs are not
conjugated and have no time.
•| can speak English.
•He could run 10
km, now he has lost
•You should do your
smoke in class
•Would you help
•Will you help me
•You may leave if
•I would bring an
umbrella, it might
Modals are different from normal verbs:
1: They don't use an 's' for the third person singular.
2: They make questions by inversion ('she can go' becomes 'can she go?').
3: They are followed directly by the infinitive of another verb (without 'to').
