Mark went to the neighborhood meeting after work. The area's city councilwoman (女议员) was leading a discussion about how the quality of life was decreasing. The neighborhood faced many problems. People were supposed to suggest solutions to the councilwoman. It was too much for Mark. "The problems are too big," he thought. He turned to the man next to him and said, "I think this is a waste of my time. Nothing I could do would make a difference here."
On his way back, Mark saw a woman carrying a grocery hag and baby. She was trying to unlock her car, but she didn't have a free hand. As Mark got closer, her other child, a little boy, suddenly darted into the street. The woman tried to reach for him, but as she moved, her bag shifted and groceries started to fall out. Mark ran to take the boy's arm and led him back to his mother. Then he picked up the groceries while the woman smiled in relief. "Thanks!" she said. "You've got great timing (适时) !"
"Just being neighborly (友好的) ," Mark said. As he rode home, he glanced at the walls of the bus passed by. On one of them was "Small acts of kindness add up." Mark smiled and thought, "Maybe that's a good place to start."
In the first paragraph, Mark thought that______.

In Africa, people learned to send messages by beating on a series of large drums (鼓). Each drum was kept within hearing distance of the next one. The drum beats were sent out in a special way that all the drummers understood. Though the messages were simple, they could be sent at great speed for hundreds of miles.
In the eighteenth century, a French engineer found a new way to send short messages. In this way, a person held a flag in each hand and the arms were moved to various positions representing different letters of the alphabet (字母表). It was like spelling out words with flags and arms.
Over a long period of time, people sent messages by all these different ways. However, not until the telephone was invented in America in the nineteenth century could people send speech sounds over a great distance in just a few seconds.
According to this passage, the Roman way of communication depended very much on______.
It has always been difficult for the philosopher or scientists to fit time into his view of the universe. Prior to Einsteinian physics, there was no truly adequate formulation of the relationship of time to the other forces in the universe, even though some empirical equations included time qualities. However, even the Einsteinian formulation is not perhaps totally adequate to the job of fitting time into the proper relationship with the other dimensions, as they are called, of space. The primary problem arises in relation to things that might be going faster than the speed of light, or have other strange properties.
Examination of the Lorentz-Fitsgerald formulas yields the interesting speculation that if something did actually exceed the speed of light it would have its mass expressed as an imaginary number and: would seem to be going backwards in time. The barrier to exceeding the speed of light is the apparent need to have an infinite quantity of mass moved at exactly the speed of light. If this situation could be leaped over in a large quantum jump---which seems highly unlikely for masses that are large in normal circumstances--then the other side may be achievable.
The idea of going backward in time is derived from the existence of a time vector that is negative, although just what this might mean to our senses in the unlikely circumstance of our experiencing this state cannot be conjectured.
There have been, in fact, some observations of particle chambers which have led some scientists to speculate that a particle called the tachyon may exist with the trans-light properties we have just discussed.
The difficulties of imagining and coping with these potential implications of our mathematical models points out the importance of studying alternative methods of notation for advanced physics. Professor Zuckerandl, in his book Sound and Symbol, hypothesized that it might be better to express the relationships found in quantum mechanics through the use of a notation derived from musical notations. To oversimplify greatly, he argues that music has always given time a special relationship to other factors or parameters or dimensions, Therefore, it might be a more useful language in which to express the relationships in physics where time again has a special role to play, and cannot be treated as just another dimension.
The point of this, or any other alternative to the current methods of describing basic physical processes, is that time does not appear---either by common experience or sophisticated scientific understanding--to be the same sort of dimension or parameter as physical dimensions, as is deserving of completely special treatment, in a system of notation designed to accomplish that goal.
One approach would be to consider time to be a field effect governed by the application of energy to mass-- that is to say, by the interaction of different forms of energy, if you wish to keep in mind the equivalence of mass and energy. The movement of any normal sort of mass is bound to produce a field effect that we call positive time. An imaginary mass would produce a negative time field effect. This is not at variance with Einstein's theories, since the "faster" a given mass moves the more energy was applies to it and the greater would be the field effect. The time effects predicted by Einstein and confirm by experience are, it seems, consonant with this concept.
The passage supports the inference that ______.
Many visitors finds the fast pace at which American people move very troubling. One's first impression is likely to be that everyone is in a rush. City people always appear to be hurrying to get where they are going and are very impatient if they are delayed even for a short moment.
At first, this may seem unfriendly to you. People will push past you as they walk along the street. You will miss smiles, brief conversations with people as you shop or dine away from home. Do not think that because Americans are in such a hurry they are unfriendly. Often, life is much slower outside the big cities, as is true in other countries as well.
Americans who live in cities often think that everyone is equally in a hurry to get things done; just as city people do in Tokyo, Singapore or Paris, for example. But When they discover that you are a stranger, most Americans become quite kindly and will take great care to help you. If you need help and say, "I am a stranger here. Can you help me？' Most people will stop, smile at you, and help you find you way or answer your questions. Occasionally, you may find someone too busy or perhaps too rushed to give you help. If this happens, do not be discouraged (气馁); just ask someone else. Most Americans enjoy helping a stranger.
Many people who first visit the United States will find that______.
SECTION B INTERVIEW
Directions: In this section you will hear everything ONCE ONLY. Listen carefully and then answer the questions that follow. Questions 1 to 5 are based on an interview. At the end of the interview you will be given 10 seconds to answer each of the following five questions.
Now listen to the interview.
听力原文：Policeman: Now, sir, I'm sorry to have kept you waiting. I had to look after the traffic on the road until some more police arrived. You're the driver of the blue car, I believe.
Mr Simpson: Yes.
Policeman: Just a few questions, sir. Do you fed all fight？
Mr Simpson: Yes, I'm... I'm fine now. I was a little shaken up at first.
Policeman: Well, I'll try not to keep you long. I just want a few details, and the rest of the information I can get tomorrow. Can I have your name and address, please？
Mr Simpson: Jeremiah Simpson, 15 Portland Crescent, Leeds.
Policeman: Have you got your driving license and insurance certificate with you？
Mr Simpson: Yes... Oh, here they are.
Policeman: M’ hm... Thank you... Oh... Yes, they're all right. Now, were there any passengers in the car？
Mr Simpson: Er yes, er my wife and a friend — a young lady. My wife was sitting in the back and her Mend in the front passenger seat.
Policeman: Where are they now？
Mr Simpson: The ambulance has just taken them to hospital. You spoke to the ambulance driver before he set off. Did he say anything about the young lady？
Policeman: He said that her injuries looked worse than they really were. The other woman -- that'd be your wife, I as same -- appeared to be suffering from shock.
Mr Simpson: Yes, I know. They advised her to go to hospital for a cheek-up, just in case...
Policeman: Mm. Was the young lady wearing her seat-belt？
Mr Simpson: No, unfortunately. I told her to put it on, but she couldn't adjust it. I didn't think it was worth stoppin the car because we were only going a few miles.
Policeman: Did she go through the windscreen？
Mr Simpson: No, she was very lucky. But she hurt her leg on tile dashboard
Policeman: Mm. It could've been much worse. Now, sir, will you tell me in your own words what happened？
Mr Simpson: Oh... Well, as you can see, I was travelling along this main road when suddenly er the other car came out of er that side street. It all happened so quickly. I just didn't see him until he hit me.
Policeman: I've just spoken to the other motorist and he says that you were speeding.
Mr Simpson: What？
Policeman: Is this true？
Mr Simpson: That's a lie. My wife and Becky'll tell you that I stopped at the pedestrian crossing just down there. You can see it's only fifty yards away. I could hardly have reached thirty miles an hour by the time I got here. Goodness knows what would' ye happened if I'd been going faster.
Policeman: The other driver said that he stopped at the junction. When he pulled out there was nobody coming, so you must at the junction. When he pulled out there was nobody coming, so your must have been speeding.
Mr Simpson: Well, it's not true. I've witnesses to prove it. He couldn't have stopped. The lighting is very good here along this stretch.
Policeman: Yes. He should have stopped. Why did you stop at the pedestrian crossing？
Mr Simpson: There were two old ladies on it. I'm always a bit careful with old people because they're likely to walk across the road without looking properly.
Policeman: I shouldn't worry, sir. We don't think you were speeding—even without measuring the skid marks.
Mr Simpson: Er, was he -- er, the other driver — drunk？
Policeman: I don't know yet. He's admitted that he's trod one or two drinks, but says it was only two half-pints. We're going to give him a breathalyser test to see whether he's over the limit. If he is, he'll be asked to have a blood test.
Mr Simpson: Well, I haven't touched a drop all night !
Policeman: No, sir. It's surprising how much a driver's breath
