解析与学生常见错误提醒
1. 参考答案:Today is not Monday. / Today isn't Monday.
解析:含有be动词(is)的句子,变否定句直接在be动词后加not。
学生常见错误提醒:错误地写成“Today not is Monday.”或“Today doesn't Monday.”。
2. 参考答案:Liu Yi does not often go swimming on Sunday. / Liu Yi doesn't often go swimming on Sunday.
解析:主语是第三人称单数(Liu Yi),谓语是实义动词(goes),变否定句需借助助动词does,后加not,并将goes还原为go。
学生常见错误提醒:忘记将动词还原(如:Liu Yi doesn't often goes...),或错误地只加not。
3. 参考答案:It is not raining in Chengdu now. / It isn't raining in Chengdu now.
解析:现在进行时(be + doing)的否定式,在be动词(is)后直接加not。
学生常见错误提醒:错误地写成“It not is raining...”或“It doesn't raining...”。
4. 参考答案:问句:Can Wang Jun play basketball?
肯定答:Yes, he can.
解析:含有情态动词can的陈述句变一般疑问句,将can提前至句首。主语Wang Jun是男性,回答时代词用he。
