神木中学“352”高效课堂高二年级英语导学案 姓名：__________ 班级：_________ 组别：_________ 内容 非谓语动词——to do，doing和done做主语和表语 课时 Period 4 主编人 张秋娟 教学 目标 1.非谓语动词功能比较 2.学习使用to do，doing和done做主语和表语的用法区别 预 习 案 一．根据汉语意思完成下列句子： 1. It is necessary_______________ a foreign language.我们有必要掌握一门外语。 2_____________ now seems impossible.现在攒钱似乎不可能。 . Travelling is _______ and we are completely _________after we are back. 旅游是有趣的，但旅游回来后我们都全累坏了。用“√”划出各类非谓语动词所作的成分： 种类 主语 表语 宾语 定语 补语 状语 to do v -ing done 深 化 选 讲深 化 选 讲Task1：To do和doing 做主语 考点1 ：用法区别：doing 表示习惯性，泛指、经常性、不具体的动作 to do表示某一次，侧重于动作的具体性和将来性 eg. 1). Doing exercises can benefit people. (强调泛指、抽象) 2). It is no good for you smok so much. (具体指你抽烟的行为) 多数情况下，这两种也可以通用。 有时为了对称，主语，宾语（或表语）要么都用to do， 要么都用doing g. Seeing is believing. To see is to believe. 但是，对于已经约定俗成，形成固定句型的，只能使用其一。 只能使用不定式to do 的情况： It is +adj+for/of sb. to do sth. eg . It is important for us express) our opinions. It is clever of him _________( work) out the problem. 2) It is a pleasure/a pity/an honor…to do sth. eg .It is an honor___________( have )a talk with you. 3) It takes/took sb. some time to do sth. eg .It takes me an hour _________ (finish) the book. 只能使用doing 的情况 1. It is no use/ no good/ no need / a waste of time+ doing 2. There is(was) no + doing/ saying/ telling 3. There is/was no use/ no good/ no sense/no point in + doing eg. There is no___________ (deny) that she is very clever. There is no ______(tell) what will happen in the future.( = It is impossible to tell….) There is no point in___________ (argue)further. 温馨提示：但在下两个句子中只能用不定式 There is no need（for sb）to do sth There is no hurry to do 考点2：doing的复合结构(doing带自己的逻辑主语）其逻辑主语一般由物主代词、名词所有格来充当。在口语中，只要不作主语，doing的复合结构中的逻辑主语可以由人称代词的宾格和名词的普通格代替。 eg: Their coming to help was a great encouragement to us. Rose’s going won’t be of much help. 判断正误：1.His being late made the teacher angry. （ ）
