下面我们来作代换练习. 这个练习里的句子都是说珍妮在寒假里已经作了的 事情. 老师先念一个句子, 然后老师给你一个新词组, 请你代换到原来的句子 里. 每作完一句老师会念出正确答案让你作个比较. 请你注意, 在你作练习的 时候你必须把老师给你的原型动词改为过去分词.
M: Jenny has done a lot of things.
M: be home with her parents
F: Jenny has been home with her parents.
M: see her old friends
F: Jenny has seen her old friends.
M: meet some new friends
F: Jenny has met some new friends.
M: go to many places with her sister,Linda
F: Jenny has gone to many places with her sister,Linda.
M: spend some time with her brother,Peter

下面我们看一看鲍勃在寒假里已经作了什么事. 请你跟刚才一样作练习.
M: Bob has stayed in the university.
M: buy his Chinese textbook
F: Bob has bought his Chinese textbook.
M: study Chinese
F: Bob has studied Chinese.
M: write two reports
F: Bob has written two reports.
M: take a job
F: Bob has taken a job.
M: work in a restaurant
F: Bob has worked in a restaurant.
三.EVER
刚才我们练习了一些现在完成式句子, 现在我们来学两个时常跟这类句子一 起用的副词, 一个是 ever, 一个是 never. 如果把 ever 这个字用在现在完成式 疑问句里就表示到目前为止是否已经作过某件事. 比方 "你吃过美国牛肉饼 吗?" 这句话英文可以这样说: Have you ever eaten a hamburger?
下面我们以代换练习的方式多练习这类句子. 练习的内容是说珍妮带了一个 从中国到美国不久的同学到她家去玩. 珍妮的弟弟彼得很好奇, 于是问他对 美国生活有多少了解, 比方吃过这个, 看过那个没有. 现在我们开始跟刚才一 样作换字练习, 作完一句就请你听老师念正确答案
M: Have you ever eaten a hamburger?
M: have coffee
F: Have you ever had coffee?
M: drive a car
F: Have you ever driven a car?
M: hear an American song
F: Have you ever heard an American song?
M: read an American novel
F: Have you ever read an American novel?
四.NEVER
现在我们来作另外一组练习, 内容是说鲍勃带珍妮到大学附近一个广东馆子 吃中国饭. 鲍勃是中国后裔美国人, 对中国文化有了解, 可是珍妮却没有接触 过中国文化,所以鲍勃问珍妮许多问题,比方吃过广东菜没有? 用过筷子没有?
喝过绿茶没有? 珍妮只好一一用 never 答覆说从来没有. 下面就是一个例子:
M: Have you ever eaten Cantonese food?
F: No,I have never eaten Cantonese food.
现在我们开始作练习, 请你注意听鲍勃问问题, 并且在珍妮回答问题的时候 一起回答.
M: Have you ever eaten Cantonese food?
F: No, I have never eaten Cantonese food.
M: Have you ever used chopsticks?
F: No, I have never used chopsticks.
M: Have you ever had green tea?
F: No, I have never had green tea.
M: Have you ever seen a Chinese painting?
F: No, I have never seen a Chinese painting.
M: Have you ever heard a Chinese song?
F: No, I have never heard a Chinese song.
M: Have you ever gone to a Chinese movie?
F: No, I have never gone to a Chinese movie.
M: Have you ever read a book about China?
F: No, I have never read a book about China.
