5、 an architecture major, and it would be exciting to see the structures in the old city like the Colosseum and the Forum and, uh, temples.

Most importantly, it is too inefficient to learn everything

8、for yourself. Often you have to rely on other peoples advice. Like, when you travel overseas, its best to get advice from someone who has been there before. Otherwise, you might miss many of the best sites and spend too much money. Secondly, I seek advice from others because it is an important part

9、of social life. Most people like to give advice to others, because they like to think theyre being helpful. Therefore, I think learning through familys, friends, and mentors advice is better.)解析：四、BSpeaking Questi(总题数：1，分数：20.00)3.Everest University has announced that its Annual Speech Contest will

13、est again. W: Id rather not talk about that. M: You really shouldve attended last year. W: I shouldnt have backed out like that, what a shame. But I was too nervous to stand in front of hundreds of people and speak. My heart was pounding, and I felt such butterflies. M: Hey. calm down. Thats why the

19、 in the fast-food restaurant. Also, the researcher was using other people without their knowledge or permission to advance her own career by writing a book about the experience. To solve the problem, the researcher told her co-workers that she was writing a book about them. This was acceptable becau

20、se she was able to get their approval to tell their stories.)解析：听力原文 One ethical problem with participant observation is that researchers usually come from social backgrounds very different from those of the people theyre studying, so they have to be dishonest about their reason for being there. The

21、y may have to lie about who they are. For example, in one study, a researcher wanted to study fast food workers, so she got a job in a fast-food restaurant. She changed her name and lied about her work history, and pretended not to have a university education. This is where the ethical problem start

22、s. To complicate matters, the researcher used other peoples acceptance of her lies in order to advance her own career. She was pretending to be someone else, a fast-food worker, to write a book about the experience. So she was basically using other people without their knowledge or permission. One s

23、olution to the problem is to be honest about who you really are. However, this might influence the results of the study because people might not act naturally if they know theyre being observed. Another acceptable solution is to tell everyone as soon as possible after the project is completed. Thats

24、 what our fast-food researcher did. At the end of the study, she told the other workers that she was writing a book about them in order to get their approval to tell their stories. Explain the ethical problem in the participant observation study discussed in the lecture. State what the researcher di

He encourages her

26、to paint a watercolor in front of the class while shes giving a talk about watercolor. The advantage of that project is that she wouldnt have to prepare very much before the presentation. The other idea is to show three different versions of one subject, like a flower.in watercolor, a pencil sketch,

27、 and maybe a photograph. She could talk about the pluses and minuses of working in each of the three media. Um, the advantage of the second project is that she could prepare it before class, but the problem is that it would be more time-consuming. I think she should go with the second idea because s

28、he seemed nervous about doing a spontaneous watercolor, and even though it would take more time, showing the three pieces of art would be less stressful and the advanced preparation might influence the professor to give her a better grade.)解析：听力原文 Friend: What are you going to do for the project? St

29、udent: I dont know. I was hoping you could help me think of something. Friend: Well, youre such a good artist, you could talk about watercolor while youre doing one in front of the class. That would be totally awesome. If I were you, thats what Id do. Student: Maybe, but what if I make a mistake in

30、front of everyone? Friend: Come on. Youre really talented. Besides, you wouldnt have to do much preparation beforehand. Student: True. And it fits in with what weve been talking about in class. Friend: Yeah. Or, how about this? You could bring in a photograph, a pencil drawing, and a watercolor of t

31、he same subject. Something simple so it wouldnt take so much time to do, like a flower. Then you could show the advantages and disadvantages of working with different materials. Student: I could do that one ahead of time. Friend: You could, but remember, it would take a lot more time. Student: Gee,

32、thanks. Ill have to think about it, but these are both really good options.七、BSpeaking Questi(总题数：1，分数：20.00)6.Please listen carefully.（分数：20.00）_正确答案：(The professor explains that there are two theories to explain the sudden disappearance of dinosaurs 65 million years ago. One is called the Impact T

33、heory. Its a widely supported theory, and it suggests that dinosaurs died out after an asteroid impact. When a gigantic asteroid collided with Earth, the sky was darkened with dust, and sunlight couldnt get through the dust cloud. As a result, plants died, the entire food chain suffered, and dinosau

34、rs eventually died out. The other is called the Volcano-Greenhouse theory. It explains that there was a big increase in volcanic eruptions. The eruptions threw a lot of carbon dioxide into the atmosphere, and this produced a greenhouse effect. The Earths temperature warmed, and it became so hot that

35、 dinosaurs were no longer able to reproduce, which of course led to their extinction.)解析：听力原文 Now, class, Im sure youve read and heard a lot about the extinction of the dinosaurs, which occurred about 65 million years ago. People are fascinated by this topic, probably because we have yet to determin

36、e its cause. Why did these giant reptiles, who had ruled the planet for millions of years, suddenly disappear? Well, the theories are endless, but Id like to talk about two that are the most plausible. The first is known as the Impact Theory, and Id say its the most widely supported. According to th

37、is concept, there was a very large asteroid-like object that collided with Earth. The results were catastrophic: enormous explosions, earthquakes, tsunamis, raging forest fires.But most importantly, an impact of that magnitude would have thrown up large amounts of dust into the sky, so much that it

38、wouldve prevented sunlight from reaching the surface. According to the theory, plants would have died first from the lack of light, and then this decline worked its way up the food chain, until the extinction of the dinosaurs was complete. As I said, its a very well-supported theory, but theres anot

39、her one, and its called the Volcano-Greenhouse Theory. This idea holds that there was a significant increase in volcanic eruptions 65 million years ago. These eruptions released large amounts of carbon dioxide into the atmosphere, creating a greenhouse effect and causing temperatures on Earth to ris

40、e. Now, this wasnt enough to kill the dinosaurs immediately. What happened, according to the theory, was that the heated environment made it impossible for dinosaur embryos to survive. Female dinosaurs were unable to produce offspring, and, well, you can see how that would lead to the extinction of species.
