题目内容
17.瞧不起或嘲笑残疾人是错误的.It's wrong tolook down onorlaugh at disabled people.
分析 look down on,laugh at disabled people.
解答 答案:look down on,laugh at disabled people.这里是it作为形式主语,后面的动词不定式作为真正主语,表示瞧不起用动词短语look down on,嘲笑laugh at,or表示或者连接两个对等成分,这里是连接两个动词短语,at和on都是介词,后加上人,disable paople残疾人,故答案是look down on,laugh at disabled people.
点评 It+be+adj./n.(for sb./of sb.)+to do sth.该句型中的形容词通常是表示事物的特点或特征的如difficult,hard,easy,impossible,necessary,important等,此时用for;或表示人的性格特征或特点的如nice,good,bad,kind,silly,foolish,wise,clever,careless,rude,brave,cruel,careful,grateful等,这时要用 of.
