解放军文职考试：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"。这两个连词经常用在be，act，appear，behave，fell，look，seem，smell，sound，taste及其他描写行为举止的动词之后，引导一个方式从句。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。)

　　He looks as if (as though) he had been hit by lightning.

　　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。)

　　说明：as if / as though也可以引导一个分词短语、不定式短语、形容词或介词短语，例如：

　　He stared at me as if seeing me for the 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。

　　The waves dashed on the rocks as if in anger.

　　波涛冲击着岩石，好像很愤怒。

　　as if 和as though 引导的从句中的时态取决于说话者对所谈内容的态度。若说话者认为其看法是真的或可能会成为事实，从句谓语就按常规变化。

　　例如：

　　He looks as if he is angry.

　　他看上去好像生气了。

　　It looked as if there would be an exciting race.

　　看来要有一场激动人心的比赛。

　　When the soaceship leaves the earth at tremendous speed，the astronauts feel as if they are being crushed against the spaceship floor.

　　当宇宙飞船以巨大的速度离开地球时，宇航员们觉得自己好像正在被压向宇宙飞船的底壁上去。

　　如果从句的内容是不真实的，是与事实相反的，从句的谓语时态要用虚拟语气。主句谓语用一般现在时态，对从句的谓语形式没有影响。

　　例如：

　　He acted just as if he were afraid.

　　他装得好像很害怕的样子。

　　He behaves as if he were a child.

　　他的举止就像个孩子。[1]
