从句的动作同时发生或先后发生。when引导的时间 状语从句的谓语动词既可以是非延续性动词,也可 以是延续性动词。如: When we lived in town, we often went to the theatre. 我们住在城镇里的时候常去剧院看戏。
last night. 昨晚直到12点我回来他才停止工作。
7. as soon as… 意为“一……就……”, 强调主句的动 作紧接着从句的动作。如:
As soon as I arrive in Beijing, I will call you. 我一到达北京就会打电话给你。 8. so… that, such… that意为“如此……以至于……”, 引导结果状语从句。基本规则是:so后面接形容词 或副词, such后接名词。但有几点要特别注意: (1)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, 前面需加不 定冠词a或an。因此, such… that… 的句型结构可 分为以下三种:

2、 as if, as though
两者的意义和用法相同,引出的状语从句谓语 多用虚拟语气,表示与事实相反,有时也用陈 述语气,表示所说情况是事实或实现的可能性 较大。汉译常作 “仿佛……似的”,“好 像……似的”。例如:
They completely ignore these facts as if (as though) they never existed. 他们完全忽略了这些事实,就仿佛它不存在似的。 (与事实相反,谓语用虚拟语气。)
Always do to the others as you would be done by. 你希望人家怎样待你,你就要怎样待人。
As water is to fish, so air is to man. 我们离不开空气,犹如鱼儿离不开水。
Just as we sweep our rooms, so we should sweep backward ideas from our minds.
He looks as if (as though) he had been hit by lighting. 他那样子就像被雷击了似的。 (与事实相反,谓语用虚拟语气。)
It looks as if the weather may pick up very soon. 看来天气很快就会好起来。 (实现的可能性较大,谓语用陈述语气。)
2、当原因是显而易见的或已为人们所知,就用as或 since。As在语气上比since更弱。例如:
Since /As the weather is so bad, we won’t go. 由于天气很糟糕,我们不会去。
3、由because引导的从句如果放在句末,且前面有逗号, 则可以用for来代替。但如果不是说明直接原因, 而是多种情况加以推断,就只能用for了。注意for不能放 在句首。例如:
说明:as if / as though也可以引导一个分词短语、
不定式短语或无动词短语。例如:
He stared at me as if seeing me for first time. 他目不转睛地看着我,就像第一次看见我似的。
He cleared his throat as if to say something. 他清了清嗓子,像要说什么似的。
Better take more clothes in case the weather gets cold. 最好多带 些衣服,以防天气变冷。
五、结果状语从句
结果状语从句常由so…that或such…that引导。 要掌握这两个句型,首先要了解so和such与其后的词的搭配规律。
1、such是形容词,其后的中心词(即被修饰语)应该是名词。 其句式结构如下:

1、 as, (just) as…so… 二者引导的方式状语从句通常位于主句后,但 在(just) as…so…结构中位于句首,这时as从句 带有比喻的含义,意思是“正如…”,“就 像”,多用于正式文体。例如:
③ such + adj. + n.(不可数名词)+ that
He has made such rapid progress that the teacher speaks highly of him. 他进步很快,老师对他大加赞赏。
2、so 是副词,只能修饰形容词或副词。句式结构如下:
① so + adj. / adv. + that Mr. Green is so busy that he can’t leave his office.格林先生很忙,不能离开办公室。 ② so + adj. + a/an + n.(单数名词)+ that He’s so young a boy that he can’t go to school now.他是个幼小的男孩,现在还上不了学。

1、because语势最强,用来说明别人所不知的原因, 常用来回答why提出的问题。例如:
I didn’t go because I was afraid. 我因为害怕所以没去。
You must speak louder so that /in order that you can be heard by all. 你得大声点说话,以便所有人都能听得见。
