二.SHOULDN'T HAVE (来源：英语学习门户网站EnglishCN.com)

现在我们开始作练习首先我们练习 shouldn't have 加上动词过去分词的用法.

以前我们学过怎么用 shouldn't 劝人不应该作某件事情. 比方有个朋友在公共 汽车上抽烟,你看见了就告诉他: "你不应该在公共汽车上 抽烟." You shouldn't smoke on a bus. 如果你的朋友告诉你, 他昨天在公共汽车上抽了烟, 你认为他 昨天不应该抽, 你就说: You shouldn't have smoked on a bus. (来源：英语聊天室 http://chat.EnglishCN.com)

现在我们作第一组练习,学学怎么表示不赞同别人过去作的事情. 在这组练习 里你还可以学到一些跟快速食品有关系的词汇, 比方 "牛肉饼店"a hamburger joint, "乳酪牛肉饼" cheeseburger, "意大利馅饼店" a pizza parlor 等等. 练习 的作法是彼得说出一些过去时态句子, 比方: " 我去了一家快餐店, 在那儿吃 了一个烤牛肉三明治." I went to a fast food restaurant. I had a roastbeef sandwich there. 请你用 shouldn't have 加上动词过去分词把句子改成 You shouldn't have had a roastbeef sandwich there. 每作完一句, 老师就会把正 确答案念一遍给你听.

(来源：英语交友 http://friends.englishcn.com)

下面我们用代换方式练习怎么劝别人在过去应该作某件事. 练习的内容都是 说到彼得告诉玛丽他在前一天晚上吃多了肚子疼之后,玛丽劝彼得的话,比方 彼得既然吃饱就不应该再吃, 应该小心的选择食物, 肚子疼就应该看大夫,吃 药, 躺下来休息等等. 练习的作法是玛丽说一句话, 然后老师会念出一个用 过去分词开头的词组, 请你跟玛丽一起把词组代换到原来的句子里.

七.听短文回答问题

(来源：英语图片 http://photo.englishcn.com)

今天我们要听一篇介绍美国快餐店的文章. 这篇文章谈到快餐店的种类,特色, 跟受美国人欢迎的原因.

请你注意听. 等一会儿我们要根据文章内容问你几个问题. (来源：英语麦当劳 http://www.EnglishCN.com)

The favorite food in the United States is the hamburger, a kind of round sandwich of cooked ground beef. The favorite place to buy a hamburger is a fast food restaurant. At fast food restaurants, people order their food, wait a few minutes, and carry it to their tables themselves. People also take their food out of the restaurant and eat it in their cars or in their homes. At some fast food restaurants, people can order their food, pay for it and pick it up without leaving their cars.

There are many kinds of fast food restaurants in the United States. The most numerous sell hamburgers, french fries and milkshakes, which are traditionally popular foods among Americans. In addition, fast food restaurants that serve Chinese food, Mexican food, Italian food, chicken, seafood and ice cream are very numerous. (来源：英语分类信息 http://fl.englishcn.com)

The idea of a fast food restaurant is so popular that nearly every kind of food can be found in one. Fast food restaurants are popular because they reflect American life style. (来源：EnglishCN英语问答中心[e问e答])

First, they are not formal restaurants. Customers wear any type of dress when they go to a fast food place. (来源：英语学习门户网站EnglishCN.com)

Second, they are fast. People who are busy do not want to spend time preparing their own food or waiting while someone else prepares it. In fast food restaurants the food is usually ready before the customer even orders it. (来源：英语资料下载 http://download.englishcn.com)

Finally, most food in a fast food restaurant is not expensive. Therefore, people can afford to eat at a fast food restaurant often, while they may not be able to afford a more traditional and more expensive restaurant very often. (来源：EnglishCN英语问答中心[e问e答])

现在请你回答下面三个问题.每回答一个问题,老师就会念出正确答案给你听. (来源：EnglishCN英语博客基地)
