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。

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：
