连系动词seem, appear和look用法区别:
三者均属于表示状态的来连系动词，都有“好像”、“似乎”的意思，区别如下:
(1) seem 侧重指事实上似乎是那样的;look 指视觉印象，指看起来似乎如此;appear 指从表面上看似乎如此，但有时并非如此。。如:
They seemed tired and unhappy when they got home. 他们回到家时看来很累，不高兴。
Be careful! The newly waxed floor looks very slippery. 小心点!这新打蜡的地板看起来很滑。
She appears quite old. 她显得很老。
(2) 三者均可后接不定式，但 look 之后一般只限于 to be(且较少见):
The man seems / appears / looks to be very tired. 那人好像很疲劳。
He seemed / appeared to have met her before. 他以前似乎见过她。
(3) 三者均可用于 it 开头的句子，且三者之后均可接从句。如:
It seemed / as if / though the day would never end. 似乎白天永远也过不完。
It looked as if he had been ill. 他看起来像是生过病。
It seems / appears that he is very rich. 他似乎很富有。
为避免重复，appear和seem后接的 that 从句有时可用so或 not代替。如:
“Is he an honest man ?” “It seems / appears so / not.”“他是诚实的人吗?”“似乎是 / 不是。”
(4) look, seem 之后可接like短语，但 appear 之后一般不能:
You look like your father. 你看起来像你父亲。
It seemed like a disaster at the time. 在当时就好像是一场灾难。
连系动词look, sound, smell, taste 和feel的用法注意:
它们都属于表示知觉的连系动词，意思分别是“看起来”、“听起来”、“闻起来”、“尝起来”、“摸起来”。使用时注意以下几点:
(1) 通常以物作主语，表示人的知觉状态或感觉能力，虽有被动词味，但不用被动语态。如:
误:The stone is felt smooth. 这种石头摸上去很光滑。
正:The stone feels smooth.
误:The soup is tasted delicious. 这汤味道不错。
正:The soup tastes delicious.
(2) 其后均可接like短语。如:

This tastes like an orange. 这东西吃起来像桔子。
When I realized what stupid mistake I had made, I felt like a fool. 当我发现我犯了个愚蠢的错误是，我觉得仿佛是个傻子。
(3) 除look外，均不能接 to be，也均不用于进行时态(即使是look也不多见)。如:
She looks (to be) the right person for this job. 她似乎是做这项工作的合适人选。
You look / are looking very fetching in that hat with the purple dress. 你戴上那顶帽子配上这紫色衣服显得非常动人。
(4) taste和smell常与of连用，意为“有┅的味道”。如:
The room smelt of cigarettes. 房间里有烟味。
This soup tastes of chicken. 这汤有鸡的味道。
【注】feel 表示“感觉”可用于进行时。如:
How are you feeling today? 你今天感觉如何?
I’m feeling terrible. 我感到难受极了。
feel还可表示“使人感觉起来…”。如:
It feels cold here. 这儿让人觉得冷。
It feels as if a great weight had been lifted from us. 我们如释重负。
