一．主语从句
主语从句是在复合句中充当主语的从句，通常放 在主句谓语动词之前或由形式主语it代替，而本身放 在句子末尾。
1. It 作形式主语
It 作形式主语代替主语从句，主要是为了平衡句子结构，主 语从句的连接词没有变化。例如：
It is a pity that you didn’t go to see the film. It doesn’t interest me whether you succeed or not.
（that引导定语从句, 作宾语, 可以省略）
2.The suggestion that the students should have plenty of exercise is very good.
（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）
三．表语从句
表语从句在复合句中作表语的名词性从句，放在系动 词之后，一般结构是“主语＋连系动词＋表语从句”。可
以接表语从句的连系动词有be, look, remain, seem等。另 外，常用的还有the reason is that… ;It is because …和This is why…等结构。例如： 1) The question is _w_h_e_t_h_e_r_/_how we can make good preparation in such a short time. 2) This is _w__h_ywe can’t get the support of the people. 3) But the fact remains _th_a_twe are behind the other classes. 4) The reason _w__h_y__ he is late for school is _th_a_t_ he missed the early bus.

I heard that he joined the army. (2) 由what, whether (if) 引导的宾语从句，例如：
(3) It ＋ 不及物动词 ＋ 从句 It occurs to sb that… It seems that… It happened that… It appears that…
(4) It is＋ 过去分词 ＋ 从句 It is reported that… It has been proved that… It is said that…
四．同位语从句
同位语从句就是在复合句中作名词的同位语的名词性从句。
1. 同位语从句的功能 同位语从句对于名词进一步解释，说明名词的具体内容，一般由
that引导，前面名词通常是 decision order,fact,news,idea,opinion 例 如： 1) The king’s decision that the prisoner would be set free surprised all the people. 2) The order that all the soldiers should stay still is given by the general.
(2) 定语从句是形容词性的，其功能是修饰先行词，对先 行词加以限定，描述它的性质或特征；同位语从句是名词 性的，其功能是对名词进行具体内容的补充说明。例如：
1) The news that he told me is that Tom would go abroad next year.（他告诉我的消息是汤姆明年将出国。）（第一
3. 作形容词的宾语，例如： I am afraid (that) I’ve made a mistake. I am sure (that) he will win the game.
4. it 可以作为形式宾语 it 不仅可以作为形式主语，还可以作为形式宾语而真正
的宾语that 从句则放在句尾，特别是在带复合宾语的句子 中。 例如：
2. 同位语在句子中的位置 同位语从句有时可以不紧跟在它所说明的名词后面，而是被别
的词隔开。例如： He got the news from Mary that the sports meeting was put off.
3. 同位语从句与定语从句的区别
(1) 定语从句中的that既代替先行词，同时以在从句中作 某个成分（主语或宾语），而同位语从句中的that是连词， 只起连接主句与从句的作用，不充当句中任何成分。

5. 否定的转移 若 主 句 谓 语 动 词 为 think, consider, suppose,
believe, expect, fancy, guess, imagine等，其后的宾语 从句若含有否定意义，一般要把否定词转移到主句 谓语上，从句谓语用肯定式。例如： I_d_o_n__’t_t_h_i_n_k_t_h_e__d_re_s_s__fi_ts__y_o_u__w_e_l_l __我认为这件衣 服不适合你穿。
改成it作形式主语结构

4. what 与that 在引导主语从句时的区别 what 引导主语从句时在句时在从句中充当句 子成分，如主语．宾语．表语，而that 则不然。
1) What you said yesterday is right.
2. 用it 作形式主语的结构
(1) It is ＋ 名词 ＋ 从句 It is a fact that … It is an honor that It is common knowledge that
(2) It is ＋ 形容词 ＋ 从句 It is natural that… It is strange that…
1。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，宾语从句中可省略 2。 引导主语从句、表语从句和同位语从句,that不可省略。
