that引導(dǎo)的賓語從句指的是that為賓語從句的引導(dǎo)詞。賓語從句：置于動詞、介詞等詞性后面，在句子中起賓語作用的從句叫做賓語從句。賓語從句分為三類：動詞的賓語從句，介詞的賓語從句和形容詞的賓語從句。

that引導(dǎo)的賓語從句(在非正式場合that可以省略)

可跟that從句做賓語的動詞

say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。

例句：The boy believes that he will travel through space to other planets.

注意事項(xiàng)：當(dāng)主句謂語動詞是think, believe, suppose, expect等詞，而賓語從句的意思是否定時(shí)，常把否定轉(zhuǎn)移至主句表示。

例句：I don’t think it is right for him to treat you like that.

在以下情況中that不能省略

1、當(dāng)句中的動詞后接多于兩個(gè)由that引導(dǎo)的賓語從句時(shí)，第一個(gè)that可省，但后面的that不可省。

例句：He said (that) you were too young to understand the matter and that he was asked not to tell you.

2、當(dāng)主句的謂語動詞與that賓語從句之間有插入語時(shí)，that一般不可省。

例句：Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.

3、當(dāng)that從句是雙賓語中的直接賓語時(shí)，that不可省。

例句：I can’t tell him that his mother died.

注意事項(xiàng)：許多帶復(fù)合賓語的句子，that引導(dǎo)的賓語從句經(jīng)常移到句子后部，而用it作形式賓語。

例句：I find it necessary that we should do the homework on time.

賓語從句的特點(diǎn)

1.賓語從句可以作及物動詞、介詞及形容詞的賓語。

2.賓語從句的語序一律用陳述句語序。

3.連接詞that引導(dǎo)賓語從句在句中無詞義，不充當(dāng)句子成分，口語中一般可以省略。

4.whether和if都可引導(dǎo)賓語從句，但whether后可緊跟or not；whether從句可作介詞的賓語。當(dāng)if/whether引導(dǎo)賓語從句時(shí)，在從句中不做任何成分，但有具體的含義，意為“是否”。if/whether不能省略。

5.如果從句太長，可以用形式賓語it。

補(bǔ)充：從句在句子中起賓語作用的從句叫做賓語從句。
