解析与学生常见错误提醒
1. 参考答案:Wang Jun could not swim when he was six. / Wang Jun couldn't swim when he was six.
解析:含有情态动词could的句子,变否定句直接在could后加not,可缩写为couldn't。
学生常见错误提醒:在could not后错误地加to(如:Wang Jun could not to swim...),或写成couldn't。
2. 参考答案:Emma should not recycle paper. / Emma shouldn't recycle 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:在should not后错误地加to(如:Emma should not to recycle paper...),或写成shouldn't。
3. 参考答案:Liu Yi mustn't litter in the park.
解析:原句是否定句,要求改为肯定句。去掉否定词mustn't,保持情态动词must和其他部分不变。
学生常见错误提醒:忘记去掉否定词,或将must改为其他词。
4. 参考答案:问句:Did Lucas grow taller last year?
肯定答:Yes, he did.
解析:陈述句是一般过去时,动词是实义动词(grew),变一般疑问句在句首加助动词Did,并将grew还原为grow。
学生常见错误提醒:忘记将动词grew还原为原形grow(如:Did Lucas grew taller last year?),或答语中动词未还原(如:Yes, he grew.)。
5. 参考答案:问句:Can Noah solve the problem?
