appear ，seem ，look 用法及区别

appear , seem , look 看来很相似，均有“好象，看起来象”之意，其区别如下： 一、含义上的差异

appear 是指根据事物的外表表象做出判断的，但实质上并不一定如此；seem是表示说话人主观上的判断，暗含有一定的根据，往往接近事实的判断；look是根据视觉印象而得出的判断，实质上也可能如此。例如： She is fifty but she appears young . 她五十岁了，但看起来很年轻。(其实并非如此)

Se seems young . (I think he is rich .) 她看起来很年轻。(根据个人的主观判断而推断出) She looks young . 她很年轻。(从他外表可出感觉出) 二、用法上的差异

1. appear，look，seem 后均可带名词、形容语、to be 结构。

The man who came yesterday appeared / seemed / looked an hounest man . 昨天来的那个人看来是一个诚实的人。

My brother appeared (to be) happy when he heard from sister . 当我弟弟收到我妹妹来信时，似乎很高兴。

2. look 可用于进行时，而 seem , appear 一般不能。如： He is looking very happy. 他现在看起来很高兴。

3. appear 和 seem 之后可接动词不定式的一般式、完成式以及其他形式，而 look 之后除了能接to be 结构外，不接其它动词不定式形式。

She appeared to agree with you. 他好象同意你的意见。

They don’t seem to have read this novel. 他们好象没有读过这本小说。

4. look , seem 能与介词 like 构成习语，意思是“看上去象”，而 appear 却不能。例如： It seems like years since I last saw you . 自从上次见到你后，好象很久没有见到你了。 He looks like a farm.他看起来象个农民。

5. seem , look 后均可接 as if , as though 引导的表语从句，从句中既可用陈述语气也可用虚拟语气，而 appear 则不能。例如：

It seemed / looked as if he had been to Beijing. 看起来他去过北京。 6. appear 和seem 均可接 that 引导的从句，而 look 不能。

It seems / appears that we won’t finish this work today. 我们好象今天完不成这项工作。 7. appear 和 seem 可用于there be 结构中，而 look 不能。如： There appears to have been an accident . 好象出了一次事故。
