Task 2: Learn the following on your own．

1．原因状语从句

引导原因状语从句的连词有：because (因为), since (既然)，now that (既然)，as (由于)， for (因为)

because，since，as和for的区别

四者均可用来表示原因，语气依次由强至弱，区别如下：

(1) 关于 because：语气最强，表示直接原因，可用于回答 why 提出的问题、引导表语从句、用于强调句等，而其余三者均不行：

“Why didn’t he come?” “Because he was ill.” “他为什么没来?” “因为他病了。”

My stomach hurts because I have eaten too many apples. 我肚子痛因为我吃了太多苹果。

3 (2) 关于 since 与 as： 两者所表示的原因都是人们已知的，即对已知事实提供理由，而不是表示直接原因。since 比 as 语气稍强，且比 as 略为正式，它们引导的从句通常放在主句之前，有时也放在主句后：

As you weren’t there, I left a message. 由于你不在那儿，我留了个口信。

Since you are wrong, you should apologize. 你既然错了，就应该道歉。

(3) 关于 for：是并列连词(其余三者为从属连词)，有时不表示因果关系，而是对前面分句内容的解释或推断, 放在主句之后。

It must have rained last night, for the ground is wet this morning.

昨晚一定下过雨，你看今天早上地面是湿的。

2．结果状语从句

结果状语从句可以由so that(因此)，so…(that)(如此……以至于)，such…that(这样……以至于)等词引导。

Try to translate the following sentences into Chinese:

1. He didn’t plan his time well，so that he didn’t finish the work on time.

________________________________________________________________

2. He didn’t finish his homework，so (that) he was punished.

________________________________________________________________

3. He ran so fast that I couldn’t catch up with him.

________________________________________________________________

4. She is such a good teacher that all of us love and respect her.

_________________________________________________________________

5. They are such interesting books that I want to read them once again.

________________________________________________________________

归纳： so foolish such a fool

so nice a flower such a nice flower

so many / few flowers such nice flowers

so much / little money such rapid progress

so many people such a lot of people

3．目的状语从句

目的状语从句可以由so that，in order that，in case(以防)等词引起。目的状语从

4 句中常用情态动词can，could，may，might，should, would。

so that =in order that，"为了，以便"

区分目的状语和结果状语：

1. I turned up the radio，so that everyone heard the news．

2. I got up early so that I could catch the first bus.

3. We started early in order that we could arrive before dark.
