题目内容
20.We should be more careful much time on computer games.( )| A. | not to spend | B. | to not spend | C. | not to cost | D. | not take to |
分析 我们应该更加小心不要花太多时间在电脑游戏上.
解答 答案:A 分析句子结构并结合选项,此句应用固定表达be careful to do sth 小心做某事,其后的动词不定式做目的状语.由于此句的意义是否定的,所以应该用动词不定式的否定形式,其否定形式就是在to前面直接加not,构成not to do sth.故排除B.句子的主语为we,根据关键部分…much time on computer games可知这里应用固定句型sb spend some time on sth意为某人花费多长时间在什么上.故排除C,D.综合以上分析,故选A.
点评 此题考查动词不定式否定形式的表达.做题时首先根据句子的结构确定动词不定式的用法;再根据意义确定出否定形式;最后根据句中的关键词确定出动词的使用.三者结合才能选出正确答案.
