在否定句里也可以用 yet 来表示 "还没有" 作某件事. 在下面一组练习里, 老师 提出一个问句, 请学生用 yet 作否定的答覆. 这些问题谈的还是鲍勃和珍妮在 学校的生活, 比方他们是不是已经自己作饭, 是不是已经参加了学生委员会等 等. 请你注意听, 并且在学生回答问题的时候也一起回答.

M: Have Bob and Jenny cooked for themselves yet?

F: No, they haven't cooked for themselves yet.

M: Have Bob and Jenny joined the student committee yet?

F: No, they haven't joined the student committee yet.

M: Have Bob and Jenny borrowed books from the library yet?

F: No, they haven't borrowed books from the library yet.

M: Have Bob and Jenny finished a course yet?

五.听短文回答问题

现在我们来作听力测验. 首先我们还是听一段文章. 这段文章的内容是说鲍勃 和珍妮在上州立大学, 这些大学有多少学生, 教室散布在校园不同地区, 学生 们赶着上课的情况.文章里也提到美国大学生应该念什么课, 哪些是选修, 哪些 是必修,什么时候上专业课等等.

现在请你注意听.

There are thousands of colleges and universities in the United States. Nearly half of the high school graduates in America go on to college. Most, like Bob and Jenny, go to large universities. These are state universities. Some of these universities have 40,000 or more students. There are also many small universities with only a few hundred students.

Large universities have many buildings,each building for a particular subject. The buildings are in a large area. This area is the university campus. Students often must go from one class in one building to the next class in another building across campus. They may have only a few minutes between classes to go from one building to another.

When students begin the university, they must take classes in many subjects. These are the required courses. English and math are usually required courses and often a history and a science course are required too. Bob and Jenny will study mostly required courses during their first year. Later, they will specialize, and take courses in one subject.

今天这段文章比较长, 等一会儿我会请英文老师再用慢速度念一遍. 现在我们 先来听今天测验的三个问题.

第一个问题是:

M: Are all American universities the same size?

第二个问题是:

M: Do American university students study different subjects in the same building?

第三个问题是:

M: What are some of the required courses in American universities?

现在我们请英文老师用慢速度再把整段文章念一遍.
