必修二英语语法

Module 1

I. be going to 的用法

be going to结构表示按计划、打算去做某事，表示人的主管意图，有时还可表示预测有迹象要发生某事。如：

. How long is your aunt going to stay in China for a visit?

(计划、打算)

. Look at the clouds. It’s going to rain.

(有迹象要发生)

. George is putting on weight. He is going to be quite fat.

(预测)

II. be going to与will的区别

. will表示说话人认为、相信要发生的事, 不含具体时间, 可以指遥远的将来; be going to 表示按计划、打算即将发生的事。

. 二者都可以表示“意图”。但是表示事先考虑的事情用be going to, 否则用will。如: I am not going to / won’t tell him about it.

--This is a very heavy box.

--I’ll help you to carry it.

. be going to 可以用在条件句中表示将来, will则不行。如:

If you are going to attend the party, you’d better leave now.

不定式作目的状语

He broke into the house to steal something.

Many drug addicts are now in treatment centers to stop taking drugs.

He’s saving up to buy a new car.

He uses a computer to send emails.

2)有时候在不定式前面加上in order to或 so as to, 否定式为 in order not to 和so as not to:

Let’s hurry so as to go to school in time.

Let’s hurry so as not to be late for school.

She studied very hard in order to catch up with others.

She studied very hard in order not to lag behind.

Module 3

1.时间状语从句

常见的连接时间状语从句的连接词有:

when, while, as, before, after, until/till, since, ever since, whenever, as soon as, no sooner… than,

hardly / scarcely… when 等

When

When 还有意义为‘这时’，(at this time)‘那时’(at that time) 常用于下列句型：

Somebody was doing something when……某人正在做……突然……Somebody was about to do something when…….某人正要做……突然……Somebody had just done something when……某人刚刚干了……这时……

1, I was reading English when my teacher came in.

2, I was about to talk in the classroom when the teacher came in. 3, I had just made the mistake when the teacher came in .

While

观察：

While they were doing homework, someone broke into the house.

While he was still a teenager, he was a big star.

分析：while引导的从句表示“在……过程中”，强调某一段时间内主句和从句的动作在同一时期发生。从句的动作表示较长时间，因此常用延续性动词。While 表示强烈的对比关系，可译成“然而”

She is tall while I am short.

While I was studying English, he was playing football.

As

试观察：

1) As they were picking tea, the girls were singing happily.

强调两个动作同时进行

2) As he grew older, he found it difficult to compose good music.

两种情况一起发展变化

分析：as引导的从句表示“当……时；一边……一边……”，主句和从句的动作同时发生，强调伴随。有时可译为“随着”。

2.过去完成时

（1）过去完成时的构成:

“助动词had+过去分词”

The public wondered why the president hadn’t attended the top conference.

（2）过去完成时的用法:

1). 过去完成时主要用来表明在某个时间或动作之前已经发生的动作, 它表示时间是“过去的过去”。如:

The patient had died when the doctor arrived.

Up until then they had just finished half the work.

He had pressed the button before we could stop him.

When I had finished my everyday work, I did some gardening.

2). 如果发生的动作很短暂, 或两个动作紧接着发生, 则常用一般过去时代替过去完成时。尤其是在含有before, after, as soon as的复合句中, 因为它们本身的词义就可以表示出先后顺序。如:

Just before I left New York, I sent an e-mail to Mr White, my teacher in the university.

3). 过去完成时还可以表示未能实现的希望、愿望等, 常用的动词有except, hope, mean, suppose, think 等。如:

I had hoped to send him a telegram to congratulate him on his marriage, but didn’t manage it.

Mother had expected me to come to her birthday party, but I really had a lot of important work to do.

Note:

当动作紧接着发生, 次序明显时, 只需用一般过去时。

When he got home from work, he was very tired. He opened the door, turned on the light, washed his face and went to bed without taking off his clothes.

2.与某个时间段或时间点连用时, 一般过去时表示动作在这个时间发生, 而过去完成时表示动作在这个时间之前就已经完成。如:

He learned Russian during his stay in Russia.

He had already learned Russian during his stay in Russia.

3. 在间接引语中，与过去完成时连用的时间状语从句常用一般过去时代替过去完成时。如：

He told me somebody had phoned when I was out.

John said the film had been on five minutes when he got to the cinema.

1.引导原因状语从句的从属连词主要的有because, as, since,seeing (that), now (that), considering (that)，in that等

I can’t get to sleep because of the noise outside. 由于外面声音嘈杂我睡不着。

Since [As] we’ve no money, we can’t buy it. 由于我们没钱，我们无法购买它。

2.用法

（1）because引导的原因状语从句一般放于主句之后，because从句位于句首时要用逗号分开，放在句末时，可不用逗号分开。because表示直接原因，语气最强，最适合回答why 引导的疑问句。

例如：

I do it because I like it.

我做这件事是因为我喜欢。

You can trust those products because the quality never varies.

你可以信赖那些产品，因为它们的质量从来不变

（2）since引导的原因状语从句一般放于主句之前表示已知的、显然的理由(通常被翻译成“既然”)，较为正式，语气比because弱。

例如：

Since you are free today, you had better help me with my mathematics.

既然今天你休息，你最好帮我补习数学。

Since you don't trust him,you should not employ him.

你既然不信任他，你就不该雇用他。

注意：seeing (that)，now (that)，considering (that)，in that这几个词汇与since引导的原因状语从句意思相近，都表示“既然”。

例如：

Seeing (that) he refused to help us, there’s no reason that we should now hel p him.

他既然曾经拒绝帮助我们，我们现在没有理由要来帮助他。

Now (that) you are grown up, you should not rely on your parents.

既然你长大了，就不应该依靠你的父母了。

Considering (that) everybody is here, let’s begin our discussion.

既然大家都到了，我们就开始讨论吧。

In that he is ill, he feels unable to do it.

因为有病，他觉得做不了那件事。

3. as 引导原因状语从句时表示附带说明的“双方已知的原因”，语气比since弱，较为正式，位置较为灵活(常放于主句之前)。

例如：

As it is raining, you’d better take a taxi.

既然在下雨，你最好乘出租汽车。

As you are tired, you had better rest.

既然累了，你最好休息一下。

I went to bed early, as I was exhausted.

我睡得早，因为我筋疲力尽了。

4. for引导的是并列句表示原因但并不说明主句行为发生的直接原因，只提供一些辅助性的补充说明，for引导的并列句只能放于主句之后并且必须用逗号将其与主句隔开。

例如：

He could not have seen me, for I was not there.

他不可能见过我，因为我不在那里。

He seldom goes out now,for he is very old.

他现在难得出门了，因为他年事已高。

注意：

①in view of the fact that可用as/since/seeing that来表示，但不能用because：

As/Since/Seeing that you are gere，you may as well give me a hand.

既然你在这里，你就帮我个忙吧。

As/Since/Seeing that Tom knows French,he'd better do the talking.

既然汤姆懂法语，最好让他来谈。

②在as/since/seeing that意指以前共知的或共知的陈述时，可用if来代替：

As/Since/Seeing/Tf you don't like Bill。why did you invite him?

既然/如果你不喜欢比尔，你为什么邀请了他？

3.考题

考题1] ____ you’ve got a chance, you might as well make full use of it. (1999)

A. Now that

B. After

C. Although

D. As soon as

[答案] A

[解析] 主句与从句之间存在因果关系，且“you’ve got a chance”表示一个显而易见的原因，因此应选用表原因的now that。

[考题2] He found it increasingly difficult to read, ____ his eyesight was beginning to fail. (2006北京)

A. and

B. for

C. but

D. or

[答案] B

[解析] “his eyesight was beginning to fail”是“he found it increasingly difficult to read”的原因，因此本题应选用可以表示原因的连词for引导原因状语从句。

[考题3] A man cannot smile like a child, ____ a child smiles with his eyes, while a man smiles with his lips alone. (2006湖南)

A. so

B. but

C. and

D. for

[答案] D

[解析] 下划线处之后的句子补充说明“a man cannot smile like a child”的原因，应选用for表原因。
