Question

16．托尼，你可以停下来去帮莉莉（Lily）学习中文．
Tony，you canstop to help Lily （to） learn Chinese．

Answer 1

分析 stop to help Lily （to） learn  Chinese．

解答 答案：stop to help Lily （to） learn  Chinese．句中can是情态动词，后加动词原形，表示停下来去做另外一件事用stop to do sth，帮助某人做某事help sb（to）do sth，学习英语learn English，故答案是stop to help Lily （to） learn  Chinese．

点评 1．stop to do sth 意为"停下来去做某事"．如：The students stop to listen to their teacher．学生们停下来去听他们老师讲话．
2．stop doing sth 意为"停止做某事"．如：The students stopped talking．学生们停止了谈话． 与它们相反的句式是：go on to do sth"继续做某事（与刚才一事不同）"和 go on doing sth"继续做某事（与刚才同一件事）"．如：He finishes his homework and goes on to study English．他完成了作业，接着继续去念英语． They went on playing games．他们继续玩游戏．
