4、实义动词的句子，变否定句分两步。       （1）如果主语是第三人称单数时，要在实义动词前加doesn't,后面的动词用原形。                 例1 He eats an apple.              &

5、#160;         否定句 He doesn't eat an apple.                    例2 Jim does his homework.             &

21、;t come in now.                       析：may作为情态动词表示“可以”时，                       其否定式用must&

22、#160; not,而不用may   not.                例7 He may watch TV .                      He mustn't watch TV.
