九年级英语上册

Unit2 I think that mooncakes are dilicious

一、语法要点:

(一)宾语从句:

宾语从句就是由一个句子来构成主句的宾语

We know (that) he likes English.

主语 谓语 宾语

1、宾语从句三要素:连接词、语序、时态

①连接词:

1)that(即陈述句作宾语从句。that在从句中不充当任何句子成分,只起连接主句和从句的作用。that不用翻译出来,在口语中常省略。)

The girl said, “I can help him.” →The girl said (that) she could help him.

2)if/whether(whether或if在句中不充当任何句子成分,只起连接作用,但不能省略。翻译成“是否”。 主句 + if / whether + 由一般疑问句变成的陈述句形式。)

Li Lei wonders . Is Jim in ? → Li Lei wonders if Jim is in.

- 1 -

3)who,whose,what,how,which,how many,how much等。(原有的特殊疑问词+句子剩余部分的陈述句形式)

He asks me, “What does your father do?” →He asks me what my father does.

②时态:

①当主句是一般现在时,从句用该用的时态(即从句的时态不受影响)

②当主句是一般过去时态,从句必须用过去的某一时态。

I don't know when he will come back.我不知道他将何时回来。

He tells me that his sister came back yesterday.他告诉我他姐姐昨天回来了。

The children didn't know who he was.孩子们不知道他是谁。

He asked his father how it happened.他问他父亲这件事是如何发生的。

③如果宾语从句所表示的是客观事实、普遍真理、自然现象或习惯性动作等,不管主句用什么时态,从句时态都用一般现在时。如:

The teacher said that the earth goes round the sun.老师说地球绕着太阳转。

2、特别强调:if 与whether 的区别(一般情况下可以相互代替,下列情况不可替代)

①与or not 连用只能用whether

- 2 -

I don’t know whether he will come or not.

②介词后只能用whether

That depends on whether he can come back.

③后与to do 不定式连用只能用whether

He wondered whether to stay here the next week.

④句首只能用whether

Whether he will come is not decided.

注意:宾语从句的否定转移:如果主句的谓语动词是 think, believe, guess 等,而且主句的主语又是第一人称时,它后面接的宾语从句的否定词通常要前移到主句中,即否定主句中的动词,而从句用肯定形式.(主语为第一人称,否定在主句,翻译在从句。)

I don’t think it will rain.我认为不会下雨。

We don’t believe that he has gone. 我们相信他还没走。

(二)感叹句:

1、感叹句是表示惊讶、赞美、喜悦、愤怒等情感的句子,通常由what或how引导。常见结构:

- 3 -

1)What a/an+形容词+可数名词的单数(+主语+谓语)!

What a clever boy he is!他是多么聪明的一个男孩啊!

2)What+形容词+可数名词的复数(+主语+谓语)!

What good students you are!你们是多么好的学生啊!

3)What+形容词+不可数名词(+主语+谓语)!

4)How+形容词或副词(+主语+谓语)!

How interesting the storyis!这个故事多么有趣啊!

How fast the boy runs!那个男孩跑得真快啊!

5)How+主语+谓语! (句子)

How I miss my mother!我多么想念妈妈啊!

2、陈述句改为感叹句常使用“一断二加三换位”的方法:

(1)“一断”,即在谓语动词后边断开,把句子分成两部分

She is~a beautiful girl. He works ~hard.

- 4 -

(2)“二加”,即如果第二部分的第一个词为形容词、副词,就加上how;如果是名词(词组),就加上what。

She is~(what)a beautiful girl. He works ~(how) hard.

(3)“三换位”,即把第一部分与第二部分互换位置,同时把句号换为感叹句。

What a beautiful girl she is! How hard he works!
