解析与学生常见错误提醒
1. 参考答案:There is not a swing in the playground. / There isn't a swing in the playground.
解析:There be句型的否定式,在be动词(is)后直接加not。
学生常见错误提醒:错误地在there后加助动词don't/doesn't,如“There doesn't is a swing...”。
2. 参考答案:Lucas cannot drive a bus. / Lucas can't drive a bus.
解析:含有情态动词can的句子,变否定句直接在can后加not。
学生常见错误提醒:在can not后错误地加to,或写成“cann't”。
3. 参考答案:Wang Jun is not washing clothes now. / Wang Jun isn't washing clothes 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“Wang Jun not is washing...”或“Wang Jun doesn't washing...”。
4. 参考答案:问句:Are there any computer rooms on the third floor?
肯定答:Yes, there are.
解析:There be句型的一般疑问句,将be动词(are)提前至句首。肯定句中的some在疑问句中要变为any。
学生常见错误提醒:忘记将some变为any,或答语不简练。
5. 参考答案:问句:Must Emma look left and right before crossing the road?
肯定答:Yes, she must.

6. 参考答案:问句:Would Liu Yi like a bowl of noodles?
肯定答:Yes, he would.
解析:含有would的陈述句变一般疑问句,将would提前至句首。
学生常见错误提醒:忘记将would提前,或答语中用“Yes, he likes.”。
7. 参考答案:问句:Does Noah often clean his room on Sundays?
肯定答:Yes, he does.
解析:主语是第三人称单数(Noah),谓语是实义动词(cleans),变一般疑问句在句首加助动词Does,并将cleans还原为clean。
学生常见错误提醒:忘记将动词还原,或答语中动词未还原。
8. 参考答案:What's the matter (with you)?
解析:对身体感受(thirsty)提问,用固定句型“What's the matter?”。
学生常见错误提醒:用How提问,或漏掉“the matter”。
9. 参考答案:What is she? / What does she do?
解析:对职业(a doctor)提问,用What。可用两种句型。
学生常见错误提醒:用Where提问,或遗漏助动词does。
10. 参考答案:Where is the milk?

学生常见错误提醒:用What提问,或将be动词遗漏。

学生常见错误提醒:忘记改变指示代词和be动词,或名词复数形式错误(如:knifes),或错误地改变形容词形式。
