M: What are you studying now？ W: l am taking three general courses and American history and American literature this semester. Last semester I took four requirements and freshman French. M: I believe it's not too late to change your major because you've mainly taken general requirements which all freshmen have to take. Also we have twelve electives so the two literature courses will be included in them, so you can change your major without losing any credit hours. W: I am very happy to know I am still able to change my major. I am interested in writing newspaper articles, and after finishing my degree I would like to work for some newspaper firm. M: Oh, I think you will be a good writer. W: Dr. Steven, when do students start practical training？ M: They don't begin practical training in reporting until the sophomore year. Journalism normally is taken in the freshman year as a general background course. W: I see. I will take the course next semester. Thank you, very much for your help. M: You're welcome. I look forward to seeing you in my department. How many courses did the woman take last semester？ A．3. B．4. C．5. D．6.

In the 1700s, height and weight became an important part of beauty. During the time of the French Revolution, many women used to wear corsets, belts that made their waists appear much slimmer. In England in the 1500s, makeup became an important part of beauty. Some women used to paint their .face white. They thought this made them more attractive. Later, in North America, some women used to eat arsenic, a dangerous poison, to make their faces whiter. By the 1860s, American women started using makeup to make themselves more charming. In the 1890s, Americans discovered that bicycle tiding could actually improve their appearance! They exercised in order to look and feel better. The popularity of bicycle riding even led to a change in fashion. American women began to wear shorter skirts instead of the. traditional long, full ones. Although diet and exercise are still popular ways of improving one's appearance, there are some parts of the body that cannot change without the help of a cosmetic surgeon. In the past, American women used to spend weeks repeating words that started with the "P" because they wanted to change the shape of their mouths. Today a cosmetic surgeon can reshape the nose or lips in a few hours. Rhinoplasty, the reshaping of nose, can greatly improve a person's image. Surprisingly, cosmetic surgery has been used for centuries in China and India. Today it is used in many countries to improve the outlook of people who have been hurt in fires or in car accidents It is also used to improve the appearance of children who are born with physical problem. Questions: 15.What is the topic of the lecture？ 16.What did women in North America do to improve their appearance in 1890s？ 17.What do you think is the speaker's attitude towards rhinoplasty？ 18.Which statement is NOT true according to the lecture？ (35) A．Why people will take plastic surgery. B．How cosmetics develop in its long history. C．How the change of fashion led to the development of cosmetic surgery. D．How people from all over the world make themselves look better.

2. Yet the implication that rapid change is a new phenomenon is again misleading. If you measure the time it takes for a technology to become widely diffused, today's experience does not seem unusual. Take the car. The basic patent for an internal-combustion engine capable of powering a car was fried in 1877. By the late 1920s—50 years later—over half of all American households owned a car. 3. The comparable dates for the computer axe harder to tie down, but the first big computer, based on vacuum valves, was built in 1946. The transistor—the first semiconductor device—was invented at Bell Laboratories in 1948. The first patent for an integrated circuit was filed in 1959. Now, in 1999-50 years after the first one was built—around half of American households own a computer. The pace of introduction has been similar to that of the car. 4. You have to cheat, choosing only the date for the personal computer, say(mid-1970s), or the internet (ditto) to make it seem much more rapid. Comparing its diffusion among private users is, you might say, unfair to the computer, for that machine's main use is in businesses. On that measure, the best historical analogy is with electrification, and the spread of the electric dynamo into factories. 5. According to Paul David, a historian at Stanford University in California, the first electricity-generating stations had been installed in New York and London in 1881, but it was well into the 1920s before the dynamo became widely used and started to raise productivity. The adoption of the computer in business has also been slow, and failed to have any measurable impact on productivity until very recently.

But the human mind can glimpse a rapidly changing scene and immediately disregard the 98 percent that is irrelevant, instantaneously focusing on the monkey at the side of a winding forest road or the single suspicious face in a big crowd.
