The Secret Life of a Helpful Modal

Many people say that modal verbs ___ us express ability.

For example, we ___ say 'I can swim' to show what we can do.

Moreover, modal verbs ___ also help us make requests.

When we say 'Could you help me?', it shows politeness, and we ___ use 'could' for this.

So next time you speak, remember that modal verbs ___ make communication easier.
