2007级第二次模拟测试试题参考答案作文参考范文Will E-books replace traditional books?Recent decades have seen the rapid development of information technology, and thereby E-books have wound their way into our daily life. Because of the wide and quick popularity of E-books, there has been an increasing controversy over the question of whether E-books will replace traditional books or not.Many people hold the idea that it will not take long for E-books to replace traditional books because E-books have quite a few advantages over traditional ones. First, E-books are more accessible to readers, because the readers just need to log onto the internet and read online. Second, thanks to the advanced technology, the cost of E-books is much lower, so it takes readers far less money to buy E-books. Last but not the least, reading E-books has developed into part of our daily life, which is particularly appealing to young users, who are the body part of the users of electronic products.As far as I’m concerned, it is not likely for E-books to replace traditional books for lots of reasons. For example, long time of reading E-books will do more harm to our eyes, and readers will find themselves more accessible to printed materials because computers and the internet haven’t yet been popular ized to every corner of our life.快速阅读 1.

I hear it’s quite an interesting book.W: I’ve just finished it, I really recommend it.Q: What does the man and woman discussing?14.W: So you ha ve completed the experiment. You didn’t have too much trouble doing that, didyou?M: It only took me most of the day. It really isn’t much different from the one I did last time.Q: What are the man and woman discussing?15.W: Where can I find a map of the university campus? I did not expect I would get lost here.M: Have you tried the information centre?Q: What does the man imply about the information office?16.M: Could I hand in my paper a few days later? I think I still need to do more research on thesubject.W: I’m afraid that’s out of the question.Q: What does the woman mean?17.M: We’ve sure been having a lot of rain lately; this might cause more oxygen in the water.W: Haven’t we ever?Q: What do we learn from the woman’s response?18.M: I can’t believe your room is such a mess. Why don’t spend some time trying to make itclean and tidy?W: Have you been to our room? That’s Joan’s room.Q: What does the woman mean?W: Wonderful! I spent most of my time at the art museum. I especially liked the new wing. I was amazed to hear the guide explain the problems they had building it.M: Right. I just read an article that went on and on about the cost – 90 million total I thinkW: Yeah. The guide mentioned that. You could see they spared no expense.M: It looked really unusual, at least from what I saw in the picture.W: It is. The basic design is two triangles. In fact there are triangles all over.

Would you mind if I borrow the magazine so metime?W: No. I wouldn’t mind if I haven’t thrown it out yet.19.What did the woman think of the new wing of the museum?20.How had the man learned about the museum?21.According to the woman, what do the paving stones, skylights and mobile have in common?22.What was the problem with the original mobile?W: David, can I give you a hand with one of those grocery bags?M: Sure, thank you so much. Could you take this one please? I didn’t realize how heavy these bags would be.W: Why did you buy so much stuff when you have to walk back from the store?M: Well, I didn’t intend to buy a lot. But I’m having some people over and I guess I needed more than I expected.W: What’s the occasion?M: Now the people I live with, the Kremers, have been on vacation for a month and I thought I’d surprise them. I’m inviting some of their friends and families for a welcome home dinner. W: Oh, that’s really thoughtful of you.M: I figure it’s the best I can do for them. They’ve been letting me stay with them rent-free while I’m in school.W: Really? That’s pretty generous of them.M: Well, they understand how difficult it is to make ends meet when you’re a student. They’ve been such a big help to me. I thought that this might be a small way to thank them for the generosity.23.What is David trying to do?24.Why did David buy so much stuff when he had to walk home?25.Why is David appreciative of the Kremers?Passage OneHave you ever had travel problem because you airplane was late? It is a common problem and it is getting worse. Airport delays make people angry and cost the country billions in lost work time.The Federal Aviation Administration or FAA is the government agency that oversees air travel. They studied the problem of airline delays.They found eleven major problems and proposed eleven ways to fix them. Some of the problems are caused because different regions of the country do things differently. Also, more planes are flying. A strong economy has more people using airplanes to get round. Airplanes are a form of mass transportation now, like trains and buses were in the past. More planes in the airport cause delays. Weather is another main reason for delays. Weather causes about 70 % of delays. Fog or freezing rain can cause delays.The first thing the FAA wants to do is take control away from the regions during heavy traffic times and bad weather. A national center would make decisions on things that affect the whole country. The FAA also wants to put more distance between planes in the sky when the weather is bad. This rule could cause even more delays.The FAA knows that their solutions will not cure the problems with airport delays. But, they hope to make things better. There are just too many planes, too few traffic controllers, and not enough new technology.26.What is the problem studied by FAA?27.What is the main cause of airline delays according to the study?28.Why is it likely that the FAA will create more delays?Passage TwoOn March 26, 2000, the Kingdome in Seattle was destroyed. It was taken down to make room for a new stadium. The blast from the falling Kingdome caused the Earth to shake as if an earthquake had happened.Scientists placed more than 200 seismic reorders in the earth to measure the movement. They found which parts of the city shook the most. This information helped them predict which parts of the city would be damaged in a real earthquake.On February 28, 2001, the real thing happened. The earthquake was 6.8 on the Richter scale. It damaged the same parts of Seattle that scientists had predicted from the Kingdome blast. It was a slab quake. It started deep in the earth, 37 miles below the surface on the Juan de Fuca plate.Scientists have learned that deep earthquakes have very few aftershocks. The earthquake had only four. Another earthquake in California that was close to the surface had over 120 aftershocks. Scientists do not know why the deep earthquakes have fewer aftershocks.Scientists plan to set off explosive in the ground near Seattle aimed at the slab. The shockwaves from the blast will bounce off the slab and give them an idea of where the plate is and how it is moving. This will give them more information in case another real earthquake hits the area.29.How was the Kingdome in Seattle destroyed?30.Why did scientists measure the collapse of the Kingdome?31.What is most puzzling to scientists about the earthquake?32.What are scientists planning to do according to the passage?Passage ThreePeople have always looked to the sky and wondered about what they saw. As centuries of discoveries flew by, it became obvious that humans would not be content to just gaze at the solar system. We wanted to blast off into it as well.Once again, technology allowed us to accomplish our goal. On October 4, 1957, a Soviet rocket sent the first man-made satellite into space. It was called Sputnik, the Russian word for “traveler”. Even though Sputnik was nothing more than a small aluminum ball with a radio inside, it started a whole new era of space exploration.In May 1961 President John F. Kennedy challenged American scientists to land a person on the moon before the end of the 1960s. In the quest to do this, scientists faced many obstacles. For example to get a spaceship all the way to the moon and back would demand a rocket engine powerful enough to make the trip.Scientists realized that it would be difficult for one heavy rocket loaded with fuel to reach the moon. Instead, they decide to use a multistage rocket. When the fuel in one stage of a multistage rocket is used up, that stage falls away. This makes the rockets lighter, and the engine of the next stage can ignite and thrust the rocket even faster and higher.As you know, Americans successfully landed on the moon in July 1969. Since then our knowledge of the solar system has increased dramatically.33.Which of the following is NOT true of the first manned space flight?34.What is the key to building a spacecraft bound for the Moon?35.How could the scientists have made the trip to the Moon a success?The (36) highest degree that a student can earn is a doctorate. Some doctorates are (37) professional degrees, as opposed to a degree based on research. Medical students, for example, receive an M.D., from the Latin “medicinae doctor”. Future (38) lawyers receive a J.D., for “juris” or “jurum” doctor, meaning a doctor of law or laws.Someone with a PhD is a “doctor of philosophy. Many people earn a PhD, yet no t many are philosophers. The name has (39) survived since the Middle Ages when many areas of study were called philosophy.Students can receive a PhD in (40) engineering, social work education, music, history and a lot of other areas. (41) Requirements can differ from one university to another and from one area of study to another. But the National Science Foundation says American doctoral education is (42) organized around a research experience.A PhD usually requires at least three years of (43) full-time study after a bachelor’s degree. Usually, PhD candidates must have a master’s degree before they sit for special e xaminations. They have to carry out original research and (44) present their findings by writing a long paper that they have to defend before a group of experts.(45) Every year, the federal government collects information on research doctorates awarded in the United States. More than forty-three thousand students received a research doctorate in 2005.(46) Close to one-third of those doctorates went to foreign students in the United States on a temporary visa. Most of them studied engineering, physical science or life science.。
