解析与学生常见错误提醒
1. 参考答案:Lucas does not like playing basketball. / Lucas doesn't like playing basketball.
解析:主语是第三人称单数(Lucas),谓语是实义动词(likes),变否定句需借助助动词does,后加not,并将动词likes还原为原形like。
学生常见错误提醒:错误地只在动词后加not(如:Lucas likes not playing basketball...),或忘记将动词还原(如:Lucas doesn't likes...)。
2. 参考答案:They have not finished their project. / They haven't finished their project.
解析:含有助动词have的现在完成时句子,变否定句直接在have后加not,可缩写为haven't。助动词后动词用过去分词finished。
学生常见错误提醒:在have not后错误地加to(如:They have not to finished...),或将finished还原为原形finish。
3. 参考答案:Emma was not reading a book at that time. / Emma wasn't reading a book at that time.
