( )I dont think he will come here. ( ),注意：如果宾语从句是由think, believe, imagine, suppose等词引导的时候，要将从句中的否定形式转移到主句中去。,宾语从句中用it作形式宾语,We think it our duty that we should help others.I find it impossible that he should finish the work in two days.,注意：如果主句中有形容词或名词作宾语补足语时，一般用it来作形式宾语，把从句放在宾补后面。,同位语从句,在句中用作同位语的从句叫做同位语从句。同位语从句一般放在如idea, news, fact, promise, suggestion, belief, truth等含有丰富内涵的词语后面，用来说明前面那个词的具体内容。一般说来，同位语从句都用that来作连接词，而且不能省略。也可用how, when, where等。,他给了她一个承诺，他会在两个月后回来。,He gave her a promise that he would come back after two months.,试区分以下句子,Do you know the fact that he stole the car?,Do you know the fact that they were talking about?,注意：1. 如果是定语从句，它的从句肯定是不完整的，关系词肯定在句中充当成分的；而同位语从句中的that只起连接作用。 2. 定语从句是对先行词起修饰作用，而同位语从句则解释说明先行词的具体内容。,(同从),(定从),此课件下载可自行编辑修改，供参考！感谢您的支持，我们努力做得更好！,
