英语主干。
1. 词汇
2. 时态(主动语态+被动语态)
3. 从句。
1) 主语从句2) 宾语从句
3) 表语从句4) 定语从句。
5) 状语从句6) 同位语从句。
4. 其他句型：包括强调句、倒装句、not...unitl句型、虚拟语气、英语四大规则等。
i. 主语从句： 主语是个句子，或者说从句在句中充当主语。
1. 当主语是陈述句时，连接词是that 即： that(不省略)+该陈述句。
eg. 1.) that we will be late is certainwe will be late.)
2.) that he did not come yesterday is a pity. (he did not come yesterday.)
(注意) 主语从句的that一定不能省略，而宾语从句中的that可以省略。
eg. 1.) that we will be late is certain. (主语从句，that不能省略)
2.) i hope (that) we will win the game. (宾语从句，that 可以省略)
2. 当主语是一般疑问句时，连接词是whether(or not)
即： whether(or not) +该一般疑问句的陈述语序。
注意)“if” 不能引导主语从句，这要与宾语从句进行区分。
eg. 1.) whether he will go there is not known. (will he go there?)
2.) whether they can finish the job (or not) is not clear.
can they finish the job?)
3. 当主语是特殊疑问句时，连接词是特殊疑问词“8w+h”
即：特殊疑问词“8w+h” +该特殊疑问句的陈述语序。
（注：8w指的是what/where/which/who/whom/why/whose/when, h 指的是how）
eg. 1.) what he did yesterday is not known. (what did he do yesterday?)
2.) where he went yesterday is not clear. (where did he go yesterday?)
3.) which team he liked has not been decided. (which team did he like?)
4.) who won the game seems certain. (who won the game?)
5.) whom he met yesterday is not clear. (whom did he meet yesterday?)
6.) why he was late for the meeting is to be found out.
why was he late for the meeting?)
7.) whose book this is is not clearwhose book is this?)
8.) when he will arrive is not known. (when will he arrive?)
9.) how we will help the lost boy will be discussed at the meeting.
(how will we help the lost boy?)
ii. (注意一) 主语从句后置！
为了避免主语冗长，句子头重脚轻，经常用it作形式主语，主语从句放在后面作真正的主语。
eg. 1.) that we will be late is certain.
- it’s certain that we will be late.
2.) whether he will go there is not known.
- it is not known whether he will go there.
3.) where he went yesterday is not clear.
- it is not clear where he went yesterday.
it 作形式主语常用句型：(that 引导的主语从句是真正的主语)
it is possible/important/necessary/clear that...
it’s said/ reported that.. 据说/据报道…
it’s been announced/declared that...已经通知/宣布…
it seems/appears/happens that… 显然、明显、碰巧。
it’s no wonder that…并不奇怪/无疑…
注意二）主语从句中 ，谓语动词一般用单数。what引导的主语从句，谓语动词根据表语决定。
what he needs _is_ that book.
what he needs _are_ some books.
注意三）what 与 that 引导主语从句的区别。
eg. (1) what you said yesterday is right. (what did you say yesterday?)
2) that she is still alive is a puzzle. (she is still alive.)
练习题。1. _he made an important speech at the meeting was true.
a. that b. why c. what d. how
2. _we’ll go camping tomorrow depends on the weather.
a if b whether c that d where
3.__is known to us all is that america is a developed country.
a. which b. as c. what d. it
4. it’s known to us all __a form of energy .
a. water isb. that water is
c. is waterd. that water to

eg. 1.) that we will be late is certain. (主语从句，that不能省略)
2.) i believe (that) we will win the game. (宾语从句，that 可以省略)
2. 当宾语是一般疑问句时，连接词是whether(or not)/if
