从属连词是连词的一种,用来引导名词性从句和状语从句。
它们在句中引导状语从句,从属连词不充当句子成分,只起连接作用。
1. unless 如果不;除非,引导条件状语从句,相当于if…not,通常遵循“主将从现”原则。unless不能用在虚拟句中,在表示与某个客观事实相反的虚拟语气中,只能用if not。
The art club is for members only. You can’t go in unless you are a member.
这个艺术俱乐部只允许会员参加。如果你不是会员就不能进入。
引导条件状语从句的连词还有:if(如果),as long as(只要),遵循主将从现原则。如:
If you come here, I’ll pick you up at the bus station. 如果你来这儿,我就去车站接你。
As long as you work hard, you’ll get good grades. 只要你努力学习,就会取得好成绩。
2. as soon as 一……就,引导时间状语从句。如果主句是一般将来时,含有祈使句或情态动词的句子时,从句用一般现在时;如果主句是一般过去时或过去将来时,从句用一般过去时。
As soon as I finish my homework, I’ll ride to your home. 我一完成作业,就骑车去你家。
引导时间状语从句的连词还有:
when (当……的时候);while(当……的时候);before(在……以前);after (在……以后);until(直到……为止)。如:
I won’t go home until you return. 直到你回来我才回家。
3. so…that 如此……以至于,引导结果状语从句。
可构成如下句式:
so + adj./ adv. + that 从句。
so + adj. + a/an + 单数名词+that从句。
Yao Ming plays basketball so well that many Americans have become his fans.
姚明打篮球如此之好,以至于很多美国人也成了他的粉丝。
He is so clever a boy that everyone likes him. 他是一个很聪明的男孩,大家都喜欢他。
so…that与such…that
两者都有“如此……以至于……”之意。
(1)so是副词,修饰形容词或副词;而such是形容词,修饰名词(词组)。
(2)so与such均可与不定冠词和形容词连用,但位置有区别:so + adj. + a(an) + n. + that从句;such + a(an) + adj. + n. + that从句。such还可以用于such + adj.leeve + 可数名词复数 / 不可数名词结构中,而so不能。
(3)若名词前有many, much, few, little等词修饰时,用so而不用such。
so…that…句型可以和too…to…句型及enough to句型进行转换。

二、多位数的读法
