1、、从词性用法上比较1. good 只用作形容词,不用作副词,其副词形式用 well。如:He speaks good English. 他的英语说得好。He speaks English well. 他的英语说得好。2. well 既可用作副词,也可用作形容词。用作形容词时,其用法很有限,只表示“健康的”“恰当的”或“令人满意的”等。如:She is very well. 她身体很好。Things are well with us. 我们事事如意。注:一般说来,well 用作形容词时,只用作表语而不用作定语(如上例),但在美国英语中,well 表示“身体健康”时有时也可用作定语。二、从相关短语
2、用法上比较be good at 与 do well in:两者均可表示“擅长”。如:He is good at languages. 他擅长学语言。She is good at telling stories. 她擅于讲故事。They all did very well in the examination. 他们这次都考得很不错。注:表示擅长某一学科时,也可用be good in。如:He is good at in maths. 他擅长数学。2. as good as 与 as well as:用于本义时,两者均可表示“与一样好”,但 good 是形容词,而 well 是副词。如:他说英语
3、说得跟她一样好。正:He speaks English as well as her.正:His English is as good as hers.但是,用于引申义时,两者的意思很不相同:as good as 意为“几乎”“差不多”(=almost),as well as 意为“而且”。如:The work is as good as finished. 工作差不多干完了。He as good as said Im a liar. 他无异于说我撒谎。Shes clever as well as beautiful. 她不但漂亮,而且聪明。As well as breaking his leg, he hurt his arm. 他不但摔断了腿, 而且还伤了胳 (注:专业文档是经验性极强的领域,无法思考和涵盖全面,素材和资料部分来自网络,供参考。可复制、编制,期待你的好评与关注)
