MODAL VERBS

Modals are special verbs which behave very irregularly in English.Here are some important differences:

1. Modal verbs do not take "-s" in the third person.

Examples:He can speak Chinese, She should be here by 9:00.

2. You use "not" to make modal verbs negative, even in Simple Present and Simple Past.

Examples:He should not be late, They might not come to the party.

3. Many modal verbs cannot be used in the past tenses or the future tenses.

Examples:He will can go with us. Not Correct:She musted study very hard. Not Correct

Common Modal Verbs: Can, Could,May,Might, Must, Ought to ,Shall ,Should, Will ,Would.
