appear, look, seem的区别 1. 从词义上看：look 指视觉印象；appear 指外表给人的印象；这两者可能是真象也可能是假象，appear 的不确定性更大一些。seem 侧重指根据某种迹象作出的推断，也不一定是事实。 2. 从句型搭配和用法上看： (1)三者均可后接不定式，但 look 之后一般只限于 to be (且较少见)。如： 正：He seems [appears，looks] to be tired. 他好像很累了。 (2) look, seem 之后可接介词 like，但 appear 之后一般不能。如： He looks [seems] like a fool. 他看起来像个大傻瓜。 (3) appear 和 seem 不用于进行时态，但 look 有时可这样用。如： 正：He looks [is looking] well. 他看上去气色不错。误：He is seeming [appearing] well. (4) 三者均可用于 it 开头的句子，且三者之后均可接以 as if 或 as though 引导的从句，另外 appear 和 seem 之后还可接 that 引导的从句。 如：It looks [seems，appears] as if he has lost interest in his job. 看来他对自己的工作已失去了兴趣。 It seems [appears] that he is very tired. 他似乎很累了。 注：后接 that 后接从句时，有时可用 so，not 代之。 如：A：Are they reliable? 他们可靠吗? B：It seems [appears] so (not). 似乎是可靠的(不可靠)。另外， 比较以下同义句型： It seems [appears] that he is ill. ＝He seems [appears] to be ill. 他似乎病了。 look like表示“看起来像……”，说明句子的主语看起来像like后的宾格，即在like的后面一般应有“像”的对象，like后应带有宾格。如： That cat looks like a hat.那只猫看起来像一顶帽子。 Jim looks like his mother.吉姆看起来像他妈妈。 本文来源：https://www.wddqw.com/doc/cfcf2bc258f5f61fb736662e.html
