look、seem、appear 的考点用法比较

(1) 三者均为连系动词，均可后接形容词、名词、不定式作表语。如：他似乎是一个诚实的人。正：He looks [seems, appears] honest.正：He looks [seems, appears] an honest man.正：He looks [seems, appears] to be honest.正：He looks [seems, appears] to be an honest man. (2) look, seem 之后可以接介词 like, 但 appear 之后不能。如：He looks [seems] like a fool. 他看起来像个大傻瓜。 (3) 三者均可后接不定式，但 look 之后一般只限于 to be。如：正：He seems [appears, looks] to be tired. 他好像很累了。正：He seems [appears] to laugh at us. 他好像在笑我们。误：He looked to laugh at us. (4) 三者均可用于 it 开头的句子，但look 之后通常接 as if (as though)引导的从句，appear之后通常接that引导的从句，seem 之后则可接that和as if (as though)引导的从句。如：It looks [seems] as if you’re right.好像你是对的。It seems [appears] that he is ill.他似乎病了。 (5) 在there be开头的句子里，可用seem, appear, 一般不用 look。如：There seems [appears] to be something wrong with him.他好像出了什么事似的。
