2、，学生在学习过程中难以理解 难点教学方法 1.观察并总结 2.积累 教学环节 教学过程 导入 回顾非谓语动词的几种形式 知识讲解 （难点突破）I.通过观察例句理解v-ing 形式作主语的情况。1.作主语 观察并总结 Seeing is believing (眼见为实) Listening to music is my hobby.小结：此处v-ing形式为动名词，作主语时相当于一个名词，有时可以与表语互换位置，例如句2可以写成：My hobby is listening to music. 2.it 作形式主语，v-ing 作真正的主语 观察并总结 It is no use crying ov

3、er spilt milk.(覆水难收) It is a great pleasure working with you. It is nice meeting you.小结：it 在句子中作形式主语，v-ing形式作真正的主语。常用结构：It is no use/useless doing sth (做某事是没有用的); It is worthwhile doing sth（做某事是值得的）此结构也可以用It is worthwhile to do sth (做某事是值得的) II.通过观察例句例句v-ing 形式作宾语的情况 1.v-ing作动词宾语 Tom admitted cheati

4、ng in the e_am. The school doesnt permit smoking.小结：此处v-ing 形式为动名词，动名词做宾语，相当于一个名词。思考：你还能想到哪些动词后常跟v-ing 形式作宾语？能用口诀总结一下吗？ 举例：喜欢想象,避免错过：enjoy; imagine; avoid; miss (平时注意积累，并用自己的方式总结) 2.v-ing 作介词宾语 观察并总结 He is used to getting up early. I am looking forward to hearing from you soon.小结：许多由动词+介词构成的短语后常跟v-i

5、ng 形式作宾语，此处v-ing 形式为动名词，动名词做宾语相当于一个名词。类似短语还有：feel like(想要),insist on (坚持),get down to(开始做某事), devote to (致力于), object to (反对),stick to (坚持), give up(放弃) 等 思考：这两个结构意义上有什么区别？你还能想出哪些动词或动词短语既可接动名词做宾语又可接不定式做宾语吗？ remember to do sth forget to do sth remember doing sth forget doing sth 回顾：remember to do sth

6、 记住去做某事（未做）remember doing sth 记得做过某事（已做）mean to do sth 打算做某事 mean doing sth 意味着做某事 go on to do sth 继续做另一件事 go on doing sth 继续做原来的事 在学习过程中不断总结体会这两种结构的区别吧 ! 课堂练习 （难点巩固）I.单句语法填空。1.You may drink, smoke, be overweight and still reduce your risk of _(die ) early by running. （20_年全国卷I）2.I quickly lower mys
