问题描述：
把下列句子合并成含有宾语从句的复合句
1、I know...Tom comes from Beijing
I know (___)Tom____from Beijing
2、I think...He doesn't like France
I__think(___)he___France
3、I don't know...Jim left for Beijing yesterday
I don't know (___) Jim ___ ___ Beijing yesterday?
4、He tells me...They want to have a food festival
He tells me (___)they ___ to have a food festival
答
1.that,comes；
2.don't,that,likes；
3.that,left for；
4.that,want ；
这几句中,that都是做连接词的,没有什么实际意义.
时态的话有以下归纳
时态：1·主句用一般现在时,从句可用任意时.
（1.I hear (that) he often reads this book.
2.I hear (that) he is reading this book.
3.I hear (that) he will read this book.
4.I hear (that) he read this book.
5.I hear (that) he has already read this book.
但是有区别）
2·主句用过去时,从句用过去某个时态.
3·主句用过去时,从句是真理时,只用一般现在时.
