语法项目

1.不定式作状语

1)不定式作目的状语:

He broke into the house to steal something.

Many drug addicts are now in treatment centres 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.

3)不定式表示目的时,通常它的逻辑主语就是句子的主语,但如果不是的话,就要用for…

结构表示逻辑主语,如:

Mom opened the door for Jane and Betty to come in.

We are now using the series “New Standard English” for s tudents to make great progress.请注意以下结构:It is so kind of you to come and help us.

(这时,you既是to come and help us又是kind的逻辑主语)

再如:It's rude of him to say so.

4)不定式还可以作结果或原因状语:

表结果:What have I done to get all this?

She went abroad never to return.

He was so.late as to miss half of the lecture.

She is such a good student as to be respected by all her classmates.

3)such(a,an)后面跟名词:

He was so late as to miss half of the lecture.

She is such a good student as to be respected by all her classmates.

我们可以把它们改变成结果状语从句:

She is such a good student that she is respected by all her classmates.

时间状语从句

时间状语从句主要用于说明主句动词的时间,其类型颇多详见如下归纳。

1.When 引导的时间状语从句,意为“当……的时候”,when 的从句可以用延续性动词。

He was working at the table when I went in . 当我进去的时候,她正在桌旁工作。

注意:when 也可以作并列连词,表示一个动作即将或正在进行或刚完成的时候,突然发生了另一件事。

They rushed in while we were discussing problems. 当我们正在讨论问题时,他们冲了进来。

Father was cleaning the car while I was playing computer games.

注意:while 还可以表示对比意义,意为“而;却”。例如:

珍妮穿着蓝色的衣服,而玛丽穿红色的。

3.As 引导的时间状语从句,作“当……的时候,一边……一边”“随着----”解,as 的从句中可使用延续性动词,也可使用非延续性动词。例如:

5.Since 和ever since引导的从句:表示“自从……以来”,从句一般表示动作的起点,用过去时。主句表示动作延续的情况,一般用现在完成时或现在完成进行时。如果主句表示的是时间,主句可用一边现在时,也可用现在完成时。

现在完成时(延续性动词)…since+…过去时(非延续性动词)“自从……以来”

现在完成时(延续性动词)…since+…过去时(延续性动词)“自(延续性动词结束以来……”

语法二过去完成时

过去完成时由助动词had 加过去分词构成,主要表示在过去某时之前已发生的动作或情况,也可以说时“过去时间的过去”。其被动形式为“had + been + p.p” 例如:

By the end of last term, we had learned more than 3,000 English words.

到上个学期末为止我们已经学了3000 多个单词了。

注意:如果句中出现了表示过去的具体时间状语,句子的内容可为过去的实际情况或句子中的内容为历史事实时,句中的动词时态只能用一般过去时。例如:

The teacher said that it was Columbus who first discovered the American continent.

在表示某人过去未曾完成的“心愿,打算,计划,想法,许诺”等等时,hope , mean ,plan, want ,promise , intend 等位于动词必须用过去完成时。例如:

答案:1-5BBCDB 6-10ABDCC

because, as , since, for归纳:

because表示“因为”,用来表示最直接的因果关系或是听话人所不知道的原因,它所表达的语气是这四个词中最为强烈的,它所引导的原因状语从句一般要放在主句之后。

还要注意两种情况也只能用because来回答:1、用why来提问的特殊疑问句的回答,只能用because;2、在强调句中,只能用because。

例:1、He didn’t attend the meeting because he had too much work to do.

2、It is because it rained last week that they put off the match.

since在语气上仅次于because,更加强调“既然”、“由于”,用来表示大家已然知道的事实。

例:Since we have no money,we can’t buy it.

as在语气上稍弱于since,不如since正式,而且经常用于口语。

例:As he wasn’t ready in time,we went without him.

for是四个词当中表示“因为”、“由于”意思时语气最弱的一个,它实际只是对它前面的主句加以补充说明理由或推断原因,要用分号和前面的主句分开。

例:I asked her to stay to tea,for I had something to tell her.
