第21课：where和when引导的定语从句.doc

1、一.本课要点及示例在这一课里, 我们学习用 where, w-h-e-r-e, where, whom, w-h-o-m, whom 和 , w-h-e-n, when 作短句. 这些短句在句子里分别说明地点 , 人物和时间.现在我们来听彼得和玛丽两人之间的一段对话.这段对话包含了我刚才提到的三种短句的用法. 请你注意听两位英文老师的发音和语调.F: Are you going anywhere on vacation this summer?M: Yes, were going back to a national park in California where we went campi

2、ng last summer.F: How nice! Were going to California too.M: Are you going to the resort where you used to go on vacation?F: Yes, and were going to visit people whom we met there before.M: When are you coming back?F: I dont know the exact date; but Ill call you on the day when I get home.现在我请英文老师用慢速度

3、再把整段对话念一遍.F: Are you going anywhere on vacation this summer?M: Yes, were going back to a national park in California where we went camping last summer.F: How nice! Were going to California too.M: Are you going to the resort where you used to go on vacation?F: Yes, and were going to visit people whom

4、 we met there before.M: When are you coming back?F: I dont know the exact date; but Ill call you on the day when I get home.下面英文老师再把对话里包含了我们今天要学的语法的句子挑出来念给你听.M: Were going back to a national park in California where we went camping last summer.M: Are you going to the resort where you used to go on v

5、acation?F: Were going to visit people whom we met there before.F: Ill call you on the day when I get home.二.WHERE听了上面的句子你可能已经注意到说明地点, 人物和时间的短句都出现在它们所修饰的词后面. 比方有一句话: “ 彼得要到一个风景区去 “, 这句话英文可以这样说: Peter is going to a scenic area. 可是这究竟是一个什么样的风景区呢? 为了加以说明, 我们可以用一个以 where, w-h-e-r-e, where 开头的短句加以修饰, 比方:

6、“他可以搭帐篷的风景区“ a scenic area where he can set up his tent所以整句话就是: Peter is going to a scenic area where he can set up his tent.现在我们来作一组代换练习. 老师先说 : a national park where he can relax, “一个他可以去调剂身心的国家公园 “, 接着老师说: “找到许多植物“ find many plants, 学生就把老师提出的字或词代换到短句里念出来,答案就是:a national park where he can find man

7、y plants. 现在我们开始作练习. 学生作的时候请你也一起作.M: a national park where he can relaxM: go campingF: a national park where he can go campingM: set up his tentF: a national park where he can set up his tentM: go fishingF: a national park where he can go fishingM: go hikingF: a national park where he can go hikingM

8、: go swimmingF: a national park where he can go swimmingM: find many plantsF: a national park where he can find many plants刚才那组练习里的短句都是用来说明彼得所向往的国家公园. 下面一组练习是说彼得要去的地方, 比方 “一个他可以用电的露营区“ A camping area where he can have electricity, “一个他可以钓鱼的湖“ a lake where he can go fishing 等等. 我们还是以代换方式作这组练习, 每作完一句就

9、请你听老师念正确答案M: Peter is going to a national park where he can go camping.M: a scenic area where he can set up his tentF: Peter is going to a scenic area where he can set up his tent.M: a camping area where he can have electricityF: Peter is going to a camping area where he can have electricity.M: a la

10、ke where he can go fishingF: Peter is going to a lake where he can go fishing.M: a forest where he can find many plantsF: Peter is going to a forest where he can find many plants.M: a mountain where he can go hiking F: Peter is going to a mountain where he can go hiking.M: a place where he can relax

11、F: Peter is going to a place where he can relax.三.WHOM下面我们来练习用 whom, w-h-o-m, whom 作修饰人物的短句 . 另外有一个疑问词 who, w-h-o, who 也可以用来作短句修饰人物. 这两个字意思相同但是用法不同. 简单地说 who, w-h-o, who 代表主语, 比方认识玛丽的人 who knows Mary. 喜欢玛丽的人 who likes Mary 等等; 而 whom, w-h-o-m, whom 代表宾语,比方玛丽认识的人 whom Mary knows, 玛丽喜欢的人 whom Mary lik

12、es 等等. 目前在一般谈话里代表宾语的 whom 已经慢慢被淘汰, 但是在文章或是演讲里仍然还用这个字.下面我们来作代换练习, 学学用 whom 开头的短句形容玛丽的朋友, 比方她去年看到的朋友; 跟她一起旅行的朋友; 跟她交谈的朋友等等. 在学生作练习的时候请你也一起作M: friends whom Mary met last yearM: saw last summerF: friends whom Mary saw last summerM: likes very muchF: friends whom Mary likes very muchM: travelled withF: f

13、riends whom Mary travelled withM: chatted withF: friends whom Mary chatted withM: knew many years agoF: friends whom Mary knew many years ago下面一组练习是由老师问你一个问题, 比方 “玛丽要去探望谁? “ who is Mary going to visit? 接着老师说: “她去年看到的朋友“ friends whom she saw last year, 所以答案就是: Mary is going to visit friends whom she

14、saw last year. 这组练习的内容都是说到玛丽在商业旅游区的各种活动. 现在我们开始作练习.M: Who is Mary going to visit?M: friends whom she saw last yearF: Mary is going to visit friends whom she saw last year.M: Who is Mary going to have dinner with?M: people whom she met last summerF: Mary is going to have dinner with people whom she m

15、et last summer.M: Who is Mary going fishing with?M: a friend whom she likes very muchF: Mary is going fishing with a friend whom she likes very much.M: Who is Mary going hiking with?M: someone whom she has known for a long timeF: Mary is going hiking with someone whom she has known for a long time.M

16、: who is Mary going to play tennis with?M: someone whom she travels withF: Mary is going to play tennis with someone whom she travels with.现在我们再来学习用 whom 作短句.下面一组练习是由老师念两个句子, 比方:“玛丽跟人们交谈“ Mary chatted with people. 跟 “她去年认识他们“ She met them last year. 请你把第二句话改成用 whom 开头的短句, 用来修饰第一句话里的 “人们“ , 所以答案就是: 玛

17、丽跟她去年认识的人们交谈. Mary chatted with people whom she met last year.这组练习的内容也都是有关玛丽在商业旅游区的活动. 现在我们开始作练习, 每作完一句还是请你听正确答案.M: Mary chatted with people.M: She met them last year.F: Mary chatted with people whom she met last year.M: Mary took pictures of her friends.M: She travelled with them.F: Mary took pictu

19、 a drive with someone.M: She knew her.F: Mary went for a drive with someone whom she knew.四.WHEN下面我们来学习用 when, w-h-e-n, when 开头可以说明时间的短句 .第一组练习是说彼得和父母到国家公园去露营, 第一个星期就碰上暴风雨, 帐篷被吹走了, 不得不住进父母的旅行拖车里 . 下面男老师把彼得这次不愉快的经验一句一句的念出来, 每个句子都有说明时间的短句, 请你听了之后跟着女老师把句子重复一遍.M: During the month when we went camping in

20、 the national park, we had a terrible experience.F: During the month when we went camping in the national park, we had a terrible experience.M: It happened on the day when I set up my tent.F: It happened on the day when I set up my tent.M: In the afternoon when we got back from fishing, it became wi

22、ning when I got up, I found that my tent was gone.F: The next morning when I got up, I found that my tent was gone.在刚才那组练习里有一个字是 trailer, t-r-a-i-l-e-r, trailer, 这个字指的是美国人露营的时候常常用的拖车. 这种拖车就好象是带了轮子的房子 , 里头有水电还分几间屋子 . 有的拖车本身就是一辆汽车, 有的必须用一般汽车拖着. 这个字等一会儿在听力测验里还会出现. 下面老师要根据刚才那组练习提出一些问题. 请学生作肯定的答覆. 在学生回答问
