原因目的结果状语从句

原因、目的、结果状语从句讲练

一、原因状语从句通常由because, since, as, for等词来引导。

连词because, as, since, for的用法区别：

because表示原因时，用法最为广泛，语气也最强。它所引导的从句可以放在主句之前或在主句之后。

例：

1) -- Why are you always late for school? – Because my home is far from here.

你为什么总是迟到？因为我家太远。

2) He can’t come to the party because he is busy.

因为他忙，所以不能来参加这个聚会。

as在表示原因时，语气较强。它所引导的从句常放在主句之前，意思是“由于”；把众人所知的事实当作理由。

例：

1) As the bad weather, he was lost his way yesterday morning.

由于恶劣的天气，他昨天早晨迷路了。

2) As Mr. Liu is the new comer, he doesn’t have too many friends here.

刘先生由于初来乍到，因此在这儿没有太多的朋友。

since语气较弱。它所引导的从句一般放在主句之前，意为“既然”；就对方陈述的事实作为理由。

例：

1) Since Li Ming doesn’t know the answers to the problems, let’s ask Wang Lei to do it.

既然李明不知道这道题的答案，那就让王磊来回答吧。

2) Since we are good friends, please call me if you need help.

既然我们是好朋友，如需要帮助，请尽管打电话。

四、目的状语从句

在句中作目的状语的从句称为目的状语从句。常用来引导目的状语从句的有：so，so that，in order that， for fear that,in case(that),for the purpose that,lest等。目的状语从句可置于句首，句中或句尾，且从句中常有情态动词could，might，should等。

1、 in order that，so that 引导的目的状语从句

in order that常用于正式文体，可置于句首，也可置于句尾，而so that往往只置于句尾，但也有置于句首的，so that短语中有时可省略that。

They carved the words on the stone so that/in order that the future generation

should/might remember what they had done.

他们把字刻在石头上以便后代能记住他们的所作所为。

特别提示！：当so that，in order that引导的目的状语从句中的主语与主句主语一致时，可将状语从句简化为不定式作状语。如果主语不一致，转化时则需在不定式前加for短语作其逻辑主语。上面的例句可改为：

They carved the words on the stone in order for the future generation to remember

what they had done.

2、 for fear (that),in case,lest引导的目的状语从句

for fear that表示目的时，意为“唯恐，以防”，in case意为“目的是，以防”，lest意为“以防”

Take an umbrella with you lest/in case it should rain.带着伞以防下雨。
