系动词look, appear, seem可用于进行时态吗1. look用作系动词表示谈论暂时的外观时,可以用一般式或进行式,两者意义上无多大区别。如:You look [are looking] tired this evening. 今晚你好像很累。You look [are looking] a bit tired. 你看起来有点累。My boy is not looking [doesn’t look] very well. 我的孩子气色不太好。注意:look后跟like或as if时习惯上不能用进行式。如:她像她母亲。误:She is looking like her mother. 正:She looks like her mother. 她好像在做梦。误:She is looking as if she’s dreaming. 正:She looks as if she’s dreaming. 2. appear和seem用作系动词习惯上不用于进行时态。如:他似乎相当富有。误:He is appearing to be quite rich.正:He appeared to be quite rich.在我看起来他好像很正常。误:He is seeming to me quite normal.正:He seems to me quite normal.(www.yygrammar.com)
