题目内容
7.---Excuse me,but I want to use your computer to type a report.---You _______ have my computer unless you take good care of it.( )
A. | needn't | B. | mustn't | C. | shouldn't | D. | shan't |
分析 ---打扰了,我想用你的电脑打一份报告.
---如果你不好好爱护我的电脑,我将不会借给你使用.
解答 选D.shall用于主语是第二、三人称时,可以表示命令,警告或者允诺.用于主语是第一人称时,表示将来,相当于will.这里主语是第二人称you,这里就是表示警告.shan't的意思是:一定不能.shouldn't的意思是:不应该;mustn't的意思为"禁止",needn't为不必,不需要.不符合题意.故选D.
点评 考查情态动词的题,熟记动词的使用规则,根据前后文语境进行选择.
