二、从属连词
从属连词是连词的一种,用来引导名词性从句。
1. 从属连词的种类
表示时间 when(当……时);while(与……同时);as(正当……时);before(在……前);after(在……后);until(到……时候,直到……才);since(自……以来);as soon as(一……就……)
表示原因和结果 because(因为);since(既然);as(由于);so(因此)
表示条件 if(如果);unless(如果不,除非);as long as(只要)
表示让步 though, although(虽然,尽管);even if/though(即使)
表示疑问 if/whether(是否)
表示方式 as(像,如同……一样);just as(正如……一样);as if(好像)
表示比较 as...as(和……一样);not so...as(不如……);than(比……更……)
表示目的 so that(以便,为的是……)
for和because的区别:
并列连词for连接的分句只能放在句尾,前面用逗号隔开,表示补充说明或者提供推断的理由;从属连词because表示的是一种明确的因果关系,解释原因,可位于主句前,也可位于主句后,常回答why引导的问句。
2. 从属连词的用法
(1) 引导宾语从句的从属连词主要有that, if, whether等。
if引导条件状语从句,从句用一般现在时,主句用一般将来时(即主将从现)。
I'm glad that you're ready to help others. 我很高兴你乐于帮助别人。
I don't know if she has gone to Guangzhou. 我不知道她是否已经去了广州。
(2) 引导状语从句的从属连词。
①引导时间状语从句的从属连词有when, while, after, before, since, till/until, as soon as等。
We've lived here since 1994. 自1994年以来我们一直住在这里。
●when和while均可引导时间状语从句,意为“当······的时候”。when既可以引导持续性动作,又可以引导短暂性动作,而while引导的动作必须是持续性的。while还可以表示两个动作同时进行。
When he arrived home, it was just nine o'clock. 他回家时正好九点。
While she was cooking, the telephone rang.
=When she was cooking, the telephone rang.
=When the telephone rang, she was cooking.
她正在做饭时电话响了。
●since“自从……以来”,该连词所连接的从句中的谓语动词通常是过去时,主句通常是一般现在时或现在完成时。
●as soon as“一……就……”,该连词所在的句子中,若主句是一般将来时,从句要用一般现在时表示将来的意义。
●till/until引导的从句有以下两种情况:
1) 表示“直到……”,主从句都用肯定式。
2) 表示“直到……才”,主句多用非延续性动词,且谓语要用否定形式,从句用肯定形式。
I worked till it was dark. 我一直工作到天黑。
I didn't get up until my mother called me. 直到我妈妈给我打电话,我才起床。
②引导原因状语从句的从属连词有as, because, since等。
Since everybody is here, let's begin. 既然大家都在这里,我们开始吧。
③引导条件状语从句的从属连词有if, unless, as long as等。
She will not come unless he is invited. 除非被邀请,否则她是不会来的。
④引导目的状语从句的从属连词有so that, in order that等。
She left early so that she could catch the early bus.
她早早地离开了以便能赶上早班车。
⑤引导结果状语从句的从属连词有so/such... that...等。
such...that与so...that的区别:
●such是形容词,它所修饰的名词可以是可数名词,也可以是不可数名词;名词前面可以带形容词,也可以不带。如果其后是单数可数名词,前面要加不定冠词a或an。
因此,such...that的句型结构可分为以下三种:
1) such+ a/an+adj.+可数名词单数+ that从句
She is such a clever girl that she can work out the math problem quickly.
她是如此聪明的一个女孩,能很快解出数学问题。
2) such+ adj.+可数名词复数+that从句
They are such exciting movies that I want to watch them again.
它们是如此让人兴奋的电影,以至于我还想再看一次。
3) such+adj.+不可数名词+that从句
It was such bad weather that I could not go out. 天气如此糟糕,我不能外出了。
●so是副词,与形容词或副词连用,其结构是:so+adj./adv.+that从句。
He ran so fast that I couldn't catch up with him.
他跑得如此快,以至于我追不上他。
⑥引导让步状语从句的从属连词有though, although, even if/though, no matter how/what等。
●由though, although引导的让步状语从句,后面的主句不能有but,但可以用yet, still等。
Although/Though it's hard work, yet I still enjoy it.
尽管这是一份差事,但我很愿意干。
●wh-ever等疑问词可以引导让步状语从句,有时可与“no matter+ wh-”引导的让步状语从句互换。
Whatever/No matter what you do, you should do it well.
不管你做什么事,都要做好。
(2) 引导其他从句的从属连词。
that, who, whom, which, when, where, why等可以引导主语从句、表语从句和定语从句。
When the new museum will be open to the public has not been made clear. (主语从句)
这座新的博物馆何时向公众开放还没有确定下来。
