1.must/might2.can’t3.might4.must5.might/must6.must7.can’t8.mightChecktheanswer:情态动词其他用法1.may表示“允许”的否定形式是mustnot,意思是“不应该”“不许可”。e.g.

—MayItakethisbookoutofthereading-room？

—No,youmustn’t．

注意事项2.在回答由must引起的问题时,如果是否定的答复，不能用mustn’t,而需要用needn’t或don’thaveto,因为mustn’t是“不准”的意思。Eg.---MustIfinishthehomeworknow?---No,youneedn’t/don’thaveto.3.must与haveto的区别

haveto比较强调客观需要,must着重说明主观看法。另外haveto能用于更多时态,比较下面的句子：IhavetostayathomebecauseIamill.Youmustgettoschoolby7am.FinishExinthepaper.No1,2,4,5,7andthenchecktheanswers.
