2020初中英语中考各类从句及考点

复合句的概念：由一个主句和一个或一个以上的从句构成。

宾语从句

一．概念：在句中起到宾语的作用。

二．宾语从句在句中的位置：

（1）作动词的宾语：

例：I heard that he joined the army. She did not know what had happened.

(2) 作形容词的宾语

例：I am afraid that I have made a mistake.

(3) 作介词的宾语

例：Our success depends on how well we can cooperate

with one another.

三．常见考点分析：

（一）．连接词：1.引导陈述句用that（在口语或非正式文

体中常常省略）。

2.引导一般疑问句用if或whether。

注意：下列几种情况通常使用whether：（1）．在具有选择意义又有or或or not时，尤其是直接与or not连用时，往往用whether；

例：I don’t know whether he will come back or not. （2）．在介词之后用whether；

例：They are talking about whether he will win the game.

Everything depends on whether you agree with us.

3.引导特殊疑问句，只需用原来的特殊疑

问词。

（二）. 语序：尤其要注意，宾语从句的语序必须是陈述语

序：即主语一定在谓语前面。

尤其要注意whether, if以及wh-(what, why…)疑问词引导的宾语从句的语序。

例：She wants to know whether I like the film.

Do you know why winter is colder than summer?

（三）. 时态：1.主句中谓语动词是现在或将来时态时，从

句中主语不受主句位于时态的影响。例：She says that she will leave a message on his desk.

She says that sh has never been to Beijing.

2.当主句谓语动词是过去时态时，从句中的

时态一般为表示过去的某种时态（如一般过去时，过去进行

时，过去完成时，过去将来时）

例：He said there were no classes yesterday afternoon.

He said he was going to take care of the baby.

3.主句谓语动词是过去时态，宾语从句叙述某一客观真理时，宾语从句用一般现在时。例：She said that her father is twenty-eight years older than her.

The teacher told us that light travels

much faster than sound.

（四）. 否定转移：当宾语从句表示否定的意义时，若主句

主语为第一人称且谓语动词是think / believe / suppose / expect等时，应在主句上加以否定。

例：I don’t think you are right.

I don’t believe that he has finished

his work.

（五）. 注意if或when引导的宾语从句和状语从句的不同。

if / when引导宾语从句时，意思分别为“是否”和“何时”，此时它们的时态根据具体情况而定。if和when引导状语从句时，意思分别为“如果”和“当……的时候”，此时如果主句是一般将来时，从句部分则用一般现在时。

例：We a re not sure if it will snow tomorrow. If it snows, we won’t climb the South Hill.

状语从句

一．概念和分类：用来修饰主句中的动词，副词和形容词的

从句叫状语从句。分类：时间状语从句，地点状语从句，原

因状语从句,目的状语从句，结果状语从句，条件状语从句，

方式状语从句，让步状语从句和比较状语从句。

（一）. 时间状语从句：

引导时间状语从句的词有：when, as, while, after, before, since, as soon as, ever since, till, until, once, whenever, no sooner …than…, hardly…when…, the moment, every time, each time, next time, directly, immediately, by the time等

1．When引导的状语从句和While引导的状语从句的区别：When既可以引导一个持续性动作也可以引导一个短暂性动

作。While只能引导持续性动作。

例：When引导的从句 I was thin when I was a child.

The film had been on when we arrived.

While引导的从句 My Mom was cooking while I was

doing my homework.

2．Before引导的时间状语从句

（1）before引导的从句位于主句之前，一般翻译成在…之

前。

例：Before they got to the bus stop, the bus had gone.

（2）before引导的从句位于主句之后，一般翻译成…(之后)才。如果在主句中用将来时，从句要用一般时替代将来时。

例：It will be half a year before I come back.
