中考英语语法专题详解七：情态动词、系动词
中考英语语法专题详解七：情态动词、系动词在英语中，表示主语动作或状态的词就叫做动词。
根据动词的意义及在句子中的作用，可将动词分为实义动词(v)、系动词(link-v)、情态动词(modal verb)和助动词(v. aux)四种类型。
下面就跟小编一起就来看看情态动词和系动词的具体用法。

如：The parrot can speak three languages. 这只鹦鹉能讲三种语言。
Can I borrow the book from the library?我可以从图书棺借这本书吗?Shanghai can be very cold in March. 上海三月份可能会很冷。

在一般疑问句中，can/could 常用来表示请求或征求对方意见，用could 比用can语气更加委婉和客气。
