第2题

It's not technology that will determine the shape of land transport so much as political,

economic and environmental considerations. We can build stronger, quieter roads with better skid resistance now, but we don't because of the cost.

The environmental lobby has had a huge impact on car manufacturers and emission control has improved a lot. But there's still some way to go on the air pollution front, particularly for lorries which run on diesel fuel, which is bad because of its particulate emission when it is burnt.

Cars and lorries could be driven by electric motors if fuel-cells, which convert fuel into electricity without burning it, can be made more efficient. However, they've been advertised for a generation and have never really met expectations. American domination of the automotive industry makes rapid progress unlikely. Because the cost of gasoline is so low in the States, there's not much incentive to develop fuel cells and electric vehicles for widespread use.

When it comes to communication, we already have Trafficmaster, which operates from transducers on motorway bridges to gauge the speed of the traffic and warn of blockages ahead. We also have global navigation satellites that can pinpoint your position. The challenge is to provide a full driver guidance system that can tell you the best direction to go in a way you can absorb at the wheel.

The next big step in transport technology will be automated roads: regulating vehicles in convoys on motorways so that they're safer and can be packed closer together. Sensors would establish what is around each vehicle and electronic control systems would keep them moving in the right direction, at the right safe speed, with maximum comfort and economy. The technology is massively expensive now, but eventually it will become a reality. You would just pay a toll, couple your car into an electronic convoy and sit back to enjoy the journey.

Motorways will gradually become more like railways, with freight vehicles electronically coupled in trains running at relatively high speeds. At suitable intervals, they would uncouple to travel the remainder of the journey with their own driver. That's almost certainly going to happen. In Adelaide there are already buses that run on an automated route for part of their journey.

That sort of combination if personal and centralized control is the direction we're going in road transport, probably first of all for freight. Any rail system has in the end to be inflexible, it doesn't go where you want, especially in rural communities, where the nearest station can be 30 miles away. We're wedded to private cars, because of their flexibility and the pride people take in ownership -- not to mention the huge sums we've spent on the road network.

So cars aren't going to go away. But under electronic control 'they will become greener and safer. In 50 years driving your own car on a fast motorway, mixed up with lorries, and passing at a closing speed of 150 mph within a few metres of people driving other vehicles in the opposite direction will seem. completely insanity.

The word "absorb" in Paragraph 4 means ______.

A．drive

B．suck in

C．acquire

D．run

第4题

About one hundred yards along the path we got to a deep valley, on the far side of which t

he path led into some very thick bushes. Rather than go through these, I decided that if we walked along the bottom of this valley we could climb up again and rejoin the path on the far side of the bushes.

As I climbed down into the valley a bird flew off a rock on which I had put my hand. On looking at the spot where the bird had risen I saw two eggs. They were a kind that I did not have in my collection, so I placed them carefully in my bag, wrapped in a little dry grass.

As we went further down the valley the sides became steeper and not far from where I had entered it. I came to a drop of about twelve to fourteen feet. The water that rushed down all these small valleys in the rainy season had made the rock as glass. As it was too deep to climb down, I handed my gun to one of the men and slid down it. My feet had hardly touched the sandy bottom when the two men jumped down, one on each side of me. They quickly gave me the gun and asked me if I had heard the tiger. Actually, I had heard nothing, perhaps because of the noise I made sliding down the rock. The men said they had heard a tiger growling somewhere nearby, but they did not know from which direction the noise had come.

According to the passage we know that ______.

A．the writer decided to push through the thick bushes

B．the writer decided to walk along the valley

C．the writer wanted to stop climbing

D．the writer tried to find two eggs

Science seems to be getting closer to answering a very old mystery （奥秘). Homing pigeons

Science seems to be getting closer to answering a very old mystery (奥秘). Homing pigeons (信鸽) can be taken hundreds of miles from their homes. When they are let to go to fly again, they find their way home. Because of this special ability to find home, pigeons have been used as messengers for hundreds of years.

Today people even breed homing pigeons for racing as a sport. The birds are shipped to some chosen place a few hundred miles away. Then all of them are let to go together. The winner is the bird that gets home first. A good racer can make it home from 500 miles away in a single day.

The mystery of the homing pigeon is how it tells direction and how it finds home.

The first part seems to be pretty well answered, and we know of two ways that pigeons tell directions. First, they use the sun. Experiments show that homing pigeons can tell directions by the sun. What happens when the sky is darkly overcast by clouds and no one can see where the sun is？ Then the pigeons still find their way home.

Naturally, people have wondered whether pigeons might have a built-in compass—something that would tell them about the direction of the earth’s magnetic (磁的) field. Many different kinds of experiments were done. Here’s what the scientists decided after they had made experiments many times. When pigeons can see the sun, they use it as their main means(手段)of direction-finding. When they cannot see the sun, they use some special way to sense direction from the earth’s magnetic field.

But how do pigeons know which direction is toward home？ What do they use that we would call a map？ These are other questions to be answered.

Pigeons have been used as messengers because ______.

A．they have a built-in compass

B．they can cover 500 miles in a single day

C．they have special ability to tell directions

D．they can find their way home

The gravitational pull of the Earth and the Moon is important to us as we attempt to conqu

er more and more of outer-space.Heres why. As a rocket leaves the Earth, the pull of the Earth on it becomes less and less as the rocket roars out into space.If you imagine a line between the Earth and the Moon, there is a point somewhere along that line, nearer to the Moon than to the Earth, at which the gravitation pull of both the Earth and the Moon on an object is just about equal.An object placed on the Moon side of that point would be drawn to the Moon.An object placed on the .Earth side of that point would be drawn to the Earth.Therefore, a rocket need be sent only to this "point of no return" in order to get it to the Moon.The Moons gravity will pull it the rest of the way. The return trip of the rocket to the Earth is, in some ways, less of a problem.The Earths gravitational field reaches far closer to the Moon than does the Moons to the Earth.Thus it will be necessary to fire an Earthbound rocket only a few thousand miles away from the Moon to reach a point where the rocket will drift to the Earth under the Earths gravitational pull. The problem of rocket travel is not so much concerned with getting the rocket into space as it is with guiding the rocket after it leaves the Earths surface.Remember that the Moon is constantly circling the Earth.A rocket fired at the Moon and continuing in the direction in which it was fired would miss the Moon by a wide margin and perhaps continue to drift out into space until "captured" in another planets gravitational field.To reach the Moon, a rocket must be fired toward the point where the Moon will be when the rocket has traveled the required distance.This requires precise calculations of the speed and direction of the rocket and of the speed and direction of the Moon. For a rocket to arrive at a point where the Moons gravity will pull it the rest of the way, it must reach a speed called velocity of escape.This speed is about 25,000 miles per hour.At a speed less than this, a rocket will merely circle the Earth in an orbit and eventually fall back to the Earth.

This passage deals mainly with______.

A．the gravitational pull of the Earth and the Moon

B．the factors involved in firing a rocket into the outer-space

C．the gravitational fields of the Earth and the Moon

D．the speed and direction of a rocket traveling in the outer-space

To: All Department Head＜managers@hartford.com＞ From: Phil Johns＜johns@hartford.

com＞ Date: Tuesday, May 22 Subject: Greenleaf merger Dear Hartford Management, As company C.E.O, I took a lot of things into consideration regarding the merger with Greenleaf company. After careful consideration, I decided to withdraw from the proposed merger between the two companies. The merger, which would have united the two semiconductor manufacturers on May 20, was reconsidered in light of new information released yesterday. We received some unofficial financial data from our long-time partner, Elf Shipping Company. The Greenleaf Company has much more debt than described in their financial statements. Besides, we thought we needed this merger to remain successful and productive in the European market. However, a new study conducted by our business research unit has shown that our market share is increasing. Furthermore, the same study has revealed that adding Greenleafs aging facilities and larger workforce to our company would only weaken our ability to remain competitive in a constantly changing industry. On Friday, May 25, at 2: 00 p.m., I will be holding an information session to further explain this direction and to answer any questions you may have. The meeting, which will take place in the board room, will also be attended by Woody Coleman, the companys attorney. One issue we will be addressing is how the cancellation of the merger may affect positions within the company. If you have any questions or concerns you would like to raise, please submit them no later than May 23 to Woody Coleman at wcoleman@lawhartford.com. Phil Johns

What is the purpose of the e-mail？

A．To notify employees of a successful merger.

B．To report the company"s record sales.

C．To announce a change in business plans.

D．To introduce a new company lawyer to board members.

听力原文：Narrator Listen to part of a discussion in a physics class. The professor is dis

cussing Forces. Professor Well, today wed talk about Force and its representation. Student A So what is force？ Professor Well, actually, a force is a push or pull upon an object resulting from the objects interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction. Student A [interrupting] You mean if a force exists, there should be two objects. Am I right？ Professor Thats right. Er, ...For simplicity sake, all forces, interactions, between objects can be placed into two broad categories. One is contact force; the other is force resulting from action-at-a-distance. Student B [ interrupting] Action-at-a-distance？ Professor Yeah, first lets talk about contact force. Contact forces are types of forces in which the two interacting objects are physically in contact with each other. Examples of contact forces include frictional forces, tensional forces, normal forces, air resistance forces, and applied forces. These specific forces will be discussed in more detail later in Lesson 2, as well as in other lessons. Student A Uh...so many forces fall into this category. Then, what is "force resulting from action-at-a-distance"？ Professor Er, ...Action-at-a-distance forces are types of forces in which the two interacting objects are not in physical contact with each other, yet are able to exert a push or pull despite a physical separation. Examples of action-at-a-distance forces include gravitational forces, such as, the sun and planets exert a gravitational pull on each other despite their large spatial separation; even when your feet leave the earth and you are no longer in contact with the earth, there is a gravitational pull between you and the Earth. Next, electric forces, such as, the protons in the nucleus of an atom and the electrons outside the nucleus experience an electrical pull towards each other despite their small spatial separation; and magnetic forces, for example, two magnets can exert a magnetic pull on each other even when separated by a distance of a few centimeters. These specific forces will be discussed in more detail in other lessons. Student B Thats magic! I am quite familiar with the phenomenon you mentioned just now, but before this class, I had no concept of these categories of forces. Student A Er, I know very little about this, too. Professor Actually, forces exist in our daily life. Force is a quantity which is measured using the standard metric unit known as the Newton. A Newton is abbreviated by an "N". To say "10. 0 N" means 10. 0 Newtons of force. Student A [ interrupting] So Newton is the standard metric unit of force？ Professor Thats true. In fact, a force is a vector quantity. As we learned in an earlier unit, a vector quantity is a quantity which has both magnitude and direction. To fully describe the force acting upon an object, you must describe both the magnitude and the direction. Thus, "10 Newtons" is not a full description of the force acting upon an object. In contrast, "10 Newtons downwards" is a complete description of the force acting upon an object; both the magnitude, "10 Newtons", and the direction, "downwards", are given. Student B Uh, thats quite complex and easy to make a mistake. Professor Yeah. ...because a force is a vector which has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow. Such vector diagrams were introduced in an earlier unit and will be used throughout your study of physics. The size of the arrow is reflective of the magnitude of the force and the direction of the arrow reveals the direction which the force is acting. Such diagrams are known as free-body diagrams. Furthermore, because forces are vectors, the influence of an individual force upon an object is often canceled by the influence of another force. For example, the influence of a "20 Newton upward" force acting upon a book is canceled by the influence of a "20 Newton downward" force acting upon the book. In such instances, it is said that the two individual forces "balance each other", meaning there would be no unbalanced force acting upon the book. Student A That sounds interesting. Then, there should be other situations in which two of the individual vector forces cancel each other, the so-called balance, yet a third individual force exists that is not balanced by another force. Professor Thats the point. Next time we will learn how to draw the free-body diagrams, which can help you to understand the situation more easily. Now get ready to answer the questions. You may use your notes to help you answer. 24. What is the discussion mainly about？ 25. How does the professor emphasize his point about force classification？ 26. What are two key factors of force description？ 27. According to the discussion, what forces belong to action-at-a-distance forces？ Listen again to part of the conversation. Then answer the question. Professor Well, actually, a force is a push or pull upon an object resulting from the objects interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction. Student A [Interrupting] You mean if a force exists, there should be two objects. Am I right？ 28. What can be inferred about student A？ Listen again to part of the conversation. Then answer the question. Professor Thats the point, next time we will learn how to draw the free-body diagrams, which can help you to understand the situation more easily. 29. What does the professor mean when she says this？ Professor Thats the point.Narrator Listen to part of a discussion in a physics class. The professor is discussing Forces. Now get ready to answer the questions. You may use your notes to help you answer.

What is the discussion mainly about？

A．The metric unit of forces.

B．The magnitude and direction of various forces.
