主要知识点：

1、含有情态动词被动语态的构成：情态动词+be+及物动词的过去分词（Ved）

答案：should be looked after carefully

2、宾语从句的否定前移：当宾语从句跟在think、believe、suppose，expect等的

动词后，且主句主语是第一人称（I,we), 变否定句时，要在主句上否定，即“否定转移”；变反意疑问句时，附加问句要与从句一致。

【例句】:1、I think you are right.-------否定句：I don’t think you are right .

2、I don’t think he is clever,is he ?

【注】:若主句的主语是第二、三人称，变否定句时，要在从句上否定；变反意疑问句时，附加问句要与主句一致。

【例句】:They think you are right .

否定句：They think you are not right .
