1．that从句作主语时，常用it作形式主语，常见的句型有：

(1)It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that从句。It is probable that he has told her everything.他可能已经把所有事情都告诉她了。

【例】It is obvious to the students ______ they should get well prepared for their future.

A. as B. which C. whether D. that

(2)It+be+名词词组(no wonder，an honour，a good thing，a pity, no surprise, etc.)+that从句。

It's a pity that we can't go.真可惜我们不能去。

It's no surprise that our team should have won the game.不要惊奇，我们队本来就应赢得比赛。

(3)It+be+过去分词(said, reported, thought, expected, decided, announced, arranged, etc.)+that从句。

It is said that Mr Green has arrived in Beijing. 据说格林先生已经到达北京了。

It is decided that the meeting has been put off till next Monday. 根据决定这个会议已经被推迟到下周一。

(4)以下情况用虚拟语气

①It is suggested/advised/ordered/requested/required/insisted（坚持要，一定要）that sb. (should) do sth.

②It is necessary/important/strange/natural that sb. (should) do sth. 2．作动词的宾语

(1)常见的可以接that从句作宾语的动词有see，say，know, imagine, discover, believe, tell, show, think, consider, make等。在可以接复合宾语的动词之后，如think，make，consider等，可以用it作形式宾语，此时that不可省略。 We consider it necessary that he should improve his pronunciation.他应当改进他的发音，我们认为这是必要的。

He has made it clear that he will not give in. 他不会屈服的，这一点他已明

确表示了。

(2)that从句一般不能充当介词的宾语，偶尔可作except，in，but的宾语。 He differed from his classmates in that he devoted his spare time to reading． 他和他的同学不同的地方在于他把业余时间用在读书上。 其他介词后面需要用that从句作宾语时，必须用it作形式宾语。 You may depend on it that I shall always help you. 我会一直帮助你，你要相信这一点。 3．作形容词的宾语

某些形容词后常接宾语从句，这类形容词有sure, glad, certain, pleased, happy, afraid, surprised, satisfied等，连接词that可省略。 I'm afraid you don't understand what I said just now. 我担心你没有明白我刚才说了什么。

Mother was very pleased her daughter had passed the exams．妈妈很高兴，她的女儿通过了考试。 4．作表语

(1)连接词that不可省略。

(2)主句的主语是reason，则表语从句只能用that引导。

The reason why he was late for class is that he didn't catch the early bus.他上课迟到的原因是他没有赶上早班车。

(3)主句的主语是advice，suggestion，order，proposal等时，表语从句应用“should+动词原形”，should可以省略。 5．作同位语

The news that the plane will take off on time makes everyone happy.飞机将按时起飞的消息使每个人都很高兴。

注意：that引导的同位语从句与关系代词that引导的定语从句的区别

连接词that引导同位语从句时，应放在某些抽象名词之后。如 ：fact, hope, desire, thought, suggestion, idea, news,problem，possibility等，对前面的名词起补充说明的作用，连接词that只起引导同位语从句的作用，在从句中不担当任何成分，不能省略。

关系代词that引导定语从句时，关系代词that一方面起引导定语从句的作用，但另一方面，that在定语从句中担当主语或宾语。若作宾语，还可以省略。但是，引导同位语从句的that一般不能省略。

The news that our football team won the match was really encouraging．（同位语从句）

我们的足球队赢得了比赛的消息真是鼓舞人心。

The news (that) we heard on the radio was not true.（定语从句） 我们在收音机里听到的消息不是真的。

【例】 We should consider the students’ request the school library provide more books on popular science.

A. that B. when C. which D. where

【例】 The fact has worried many scientists ______ the earth is becoming warmer and warmer these years.
