谓语是句子中表示动作的句子成分,一般由动词或短语动词充当这一成分.eg she studied English last year(studied)Tina is taking care of her baby sister.(take care of)状语是修饰动词、形容词、副词和全句的句子成...take 和 by 地区别用法两者需要区别的地方应当是在接交通工具上吧。by 的后面直接接交通工具，不得添加任何冠词；by bus, by car, by biketake后面接交通工具时必须添加冠词。take a bus, take a taxi.其他方面，两者是风马牛不相及，就不用区别了吧。希望能帮到您。
