1. 主语从句(subject clause)2. 表语从句(predictive clause)3.宾语从句(bject clause)4. 同位语从句(appsitive clasue)
His jb is imprtant.
What he des is imprtant.
This is his jb.
This is what he des every day.

1.The fact that she has changed a lt surprised us. 2.The prblem whether he can get thrugh the test is wrrying me
3.The thught that we might succeed excited us.4. The idea that they shuld try a secnd time is wrth king’s decisin that the prisner wuld be set free surprised all the peple.
总结：同位语从句是对名词的 ______ ， that在从句中_________，从句成份_______。
1.同位语从句的引导词: that ,whether, hw , when, where, why等引导。that引导的同位语从句前面的名词常见的有: idea, fact, news, belief, thught, dubt, suggestin; prf, message, rder, cnclusin, desire, prblem thery, truth, wrd infrmatin等.2.同位语从句和定语从句的区别: 如果that作从句中的某一成分, 则是定语从句, 如果that不作从句中的任何成分, 则是同位语从句. 例: (1) I had n idea that it was s late. (主系表 结构, that 不作从句中的成分, 同位语从句) (2) I still remember the place that we visited last year. (主谓宾结构, that作从句中的宾 语,定语从句)
that在同位语从句与定语从句的
（I）试比较下面两个例句: 1.The suggestin that he raised at the meeting is very suggestin that the students shuld have plenty f exercise is very gd.
（that引导定语从句, 作宾语, 可以省略）
（that引导同位语从句,在从句中不担当任何成分，但不可以省略）
引导名词性从句的连接词可分为三类：　　 连接词：that, whether, if连接代词：what, whatever, wh, whever, whm, whmever，which ，whichever，whse.连接副词：when, where, hw, why
that只起连接主句和从句的作用，在从句中不担任任何成分， 本身也没有词义，宾语从句中有时可省略引导主语从句、表语从句和同位语从句时that不可省略.
注意:名词性从句应用陈述语序。
that / what
1. ______ he wants is a bk.2. ______ he wants t g there is bvius. 3. The result is ______ we wn the game. 4. This is _____ we want t knw.
5. We shuld pay attentin t ______ the 　teacher is saying. 6. I have n dubt _____ he will cme. 7. I have n idea ____ he did that afternn.
that 和what 该如何选用
that 和 what 都可引导所有的名词性从句。但是，what除起连接作用外，还在名词性从句中充当成分，可作从句的 。而that在名词性从句中不充当任何成分，只起连接作用。
1. We shuld pay attentin t ______ the teacher is saying. 2. I have n dubt _____ he will cme. 3. I have n idea ____ he did that afternn.
a. 主语从句 b. 表语从句 c. 同位语从句 d. 介词后的宾语从句 e. whether t d 做动词宾语不能用if t d. f. 与 r nt 连在一起引导宾语从句时用whether.
if和whether的选用
不能使用if 的情况:
引导主语从句在句首只能用whether,有it作形式主语的whether/if都可以。总之，在名词性从句中，whether 是万能词
1.I dn’t knw ________ r nt he is well. 2.The questin is ________ he shuld d it. 3. I asked her __________ she had a bike. 4. ________ we will hld a party in the pen air tmrrw depends n the weather. 5. We’re wrried abut ________ he is safe. 6. I dn’t knw ___________ he is well r nt.
if / whether
whether / if
其它连接代词和副词的使用
主要根据名词性从句中的具体意义，正确的选择 wh, which, when, where, why, hw 等连接词，这些连接词既具有疑问含义，又起连接作用，同时在从句中充当各种成分。
