解析与学生常见错误提醒
1. 参考答案:I do not like apples. / I don't like apples.
解析:主语是第一人称(I),谓语是实义动词(like),变否定句需借助助动词do,后加not。
学生常见错误提醒:错误地写成“I like not apples.”或“I doesn't like apples.”。
2. 参考答案:Emma does not have any milk for breakfast. / Emma doesn't have any milk for breakfast.
解析:主语是第三人称单数(Emma),谓语是实义动词(has),变否定句需借助助动词does,后加not,并将has还原为have。肯定句中的some在否定句中要变为any。
学生常见错误提醒:忘记将动词还原,或忘记将some变为any。
3. 参考答案:The panda does not eat bamboo. / The panda doesn't eat bamboo.
解析:主语是第三人称单数(The panda),谓语是实义动词(eats),变否定句需借助助动词does,后加not,并将eats还原为eat。

4. 参考答案:问句:Does Wang Jun like noodles?
肯定答:Yes, he does.
解析:主语是第三人称单数(Wang Jun),谓语是实义动词(likes),变一般疑问句在句首加助动词Does,并将likes还原为like。
