解析与学生常见错误提醒
1. 参考答案:Emma is not looking for her water bottle. / Emma isn't looking for her water bottle.
解析:现在进行时(is + 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“Emma not is looking...”或“Emma doesn't looking...”。
2. 参考答案:We should not waste paper. / We shouldn't waste paper.
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。
学生常见错误提醒:错误地写成“We not should waste...”或“We don't should waste...”。
3. 参考答案:Wang Jun is not going to graduate this June. / Wang Jun isn't going to graduate this June.
解析:含有be动词(is)的句子,变否定句直接在be动词后加not。“be going to”表示将来,其否定形式是“be not going to”。
学生常见错误提醒:在to后面加not(如:...going not to...),或在graduate后加not。
4. 参考答案:问句:Was Lucas born in Shenyang?
肯定答:Yes, he was.
解析:含有be动词(was)的一般过去时陈述句变一般疑问句,将be动词(was)提前至句首。主语Lucas是男性,回答时代词用he。
学生常见错误提醒:忘记将be动词提前,或答语中时态不一致。
5. 参考答案:问句:Is recycling important for the environment?
肯定答:Yes, it is.

7. 参考答案:问句:Do you enjoy playing basketball?
肯定答:Yes, I do.

学生常见错误提醒:答语中人称错误。
8. 参考答案:What are you looking for?
解析:对物品(my wide pencil case)提问,用疑问词What。现在进行时疑问句中be动词(are)提前。主语I变为you。
学生常见错误提醒:用Which提问,或忘记将I变为you。
9. 参考答案:What is the new classmate like? (问性格)
解析:对性格特征(friendly and helpful)提问,用固定句型What is...like? 句子是be动词is,疑问句中is提前。
学生常见错误提醒:用How提问(也可接受,但What ... like? 更准确),或用What does...look like? (这是问外貌)。
10. 参考答案:What is the temperature? 或 How many degrees is it?
解析:对温度数值(twenty-five degrees)提问,用固定句型What is the temperature? 或 How many degrees is it? 句子是be动词is,疑问句中is提前。
学生常见错误提醒:用What提问但写成不完整句子,如“What the temperature?”。

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。
15. 参考答案:The children are worried about the exams.

否定答:No, we won’t.
解析:If条件状语从句,主句变一般疑问句,将主句的助动词will提前至主句句首。主语we回答时用we。
学生常见错误提醒:将if从句中的动词也变为疑问形式(如:If will it rain...),或在答语中遗漏助动词。
