解析与学生常见错误提醒
1. 参考答案:Chen Wei should not keep quiet in the library. / Chen Wei shouldn't keep quiet in the library.
解析:含有情态动词should的句子,变否定句直接在should后加not,可缩写为shouldn't。
2. 参考答案:They cannot borrow books from the library. / They can't borrow books from the library.
解析:含有情态动词can的句子,变否定句直接在can后加not,可缩写为can't。情态动词后动词用原形。
