In the previous quizzes we have seen how verbs are classified and used in sentences. We have also seen how some verbs are supported by auxiliary verbs and linking verbs. As you have learnt in your English classes there are many verbs that help main verbs and these are known as helping verbs.
Helping verbs, as their name suggests, help improve the sentence by communicating much more than the main verb alone. Modal verbs are helping verbs that normally precede the main verb and provide additional information about the function of the main verb. CAN, COULD, MAY, MIGHT, WILL, WOULD, MUST, SHALL, SHOULD and OUGHT TO are all modal verbs. In the quiz that follows we concentrate on MAY and MIGHT, which are used to talk about actions that are possible, but not certain, either in the present or in the future.
