MODAL VERBS

Hi guys,

As you know, today we´ve been revising  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
