方式状语从句的引导词（方式状语从句）

体式格局状语从句一贯由as， (just) as…so…，as if，as though，by，with开导,多用来讨论或人的举动可能做某事的体式格局。若从句内容是不实在的从句谓语用虚拟语气。

1）as, (just) as…so…向导的体式格局状语从句日常平凡位于主句后，但在(just) as…so…组织中位于句首，这时as从句带有比方的寄义，意思是"正如…"，"就像"，多用于正式体裁，

比方：

Always do to the others as you would be done by. 你但愿人家奈何待你，你就要奈何待人。

As water is to fish, so air is to man. 我们离不开氛围，仿佛鱼儿离不开水。

Just as we sweep our rooms, so we should sweep backward ideas from our minds. 正如扫除衡宇相通，我们也要肃除我们头脑中领先的器材。

2）as if, as though二者的事理和用法雷同，引出的状语从句谓语多用虚拟口气，默示与实情类似，偶尔也用敷陈口气，默示所说情形是实情或杀青的可能性较大。汉译常作"俨然……似的"，"似乎……似的"，

比方：

They completely ignore these facts as if (as though) they never existed. 他们统统疏忽了这些原形，就如同它不存在似的。（与原形一致，谓语用虚拟语气。）

He looks as if (as though) he had been hit by lighting. 他那样子就像被雷击了似的。（与真相相同，谓语用虚拟语气。）

It looks as if the weather may pick up very soon. 看来气候很快就会好起来。（兑现的可能性较大，谓语用论述口气。）

表明：as if / as though也可以向导一个分词短语、不定式短语或无动词短语，

比方：

He stared at me as if seeing me for first time. 他全神贯注地看着我，就像第一次望见我似的。
