- Negative sentence Example: You should not ignore your studies.
Question Form of Modal Verbs
To form a question sentence with modal verbs, the modal verb is placed at the beginning of the sentence.
- Affirmative sentence Example: You can come to the party.
- Question sentence Example: Can you come to the party?
Contracted Forms of Modal Verbs
Modal verbs can be contracted when they are used in negative and question sentences. The contraction form of ‘not’ is added to the modal verb to form the negative contraction, and ‘n’t’ is added to the modal verb to form the question contraction.
- Negative contraction Example: She can’t dance.
- Question contraction Example: Can’t you come to the party?
