Modal Verbs (modal auxiliaries) II

Modal verbs are special verbs which behave very differently from normal verbs. 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 or the future tenses without changing form. Examples:
  • He will can go with us. Not Correct. He will be able to go with us. Correct
  • She musted study very hard. Not Correct. She had to study very hard.
4. All modal verbs except ought to and used to are used with the bare infinitive without to. Examples
  • must finish my homework.
  • ought to finish my homework.
