It’s illegal for the police to attach a GPS unit to your car without your permission, as the U.S. Supreme Court settled in 2012．But if the police are in hot pursuit of a bank robber or other escaping criminals that threaten public safety, a GPS tracker is acceptable. But exactly how can the police GPS track a car that is moving fast?
The answer to that question comes from StarChase，a new police technology being used by a small but growing number of law enforcement agencies．It allows the police to fire 4．5-inch glue-covered GPS bullet-like projectiles(发射体)from an air gun fixed in their police cars．If the GPS tracker makes contact with the escaping robber’s car， it’ll stick no matter how fast the vehicle is going．That way, the police will have a constant read on the car’s location and heading．Aside from simply apprehending(逮捕)criminals，it's believed this new technology could help save lives．If the police successfully fire a GPS unit at a speeding criminal，they can pull back from a high-risk chase．Chases can be incredibly dangerous to all involved，including innocent bystanders and other drivers．Once the GPS bullet connects，there's no need for the chase any longer．
Now，predictably,a GPS-loaded gun isn’t cheap. Police departments need to pay about $5．000 per vehicle for the technology,and individual GPS bullets cost as much as $250 each．That may sound expensive，but remember：The alternative is often thousands of dollars in property damage，and great human cost in injury and lost life．According to Star Chase，their GPS bullet system has an apprehension rate of 80％without any report of inury or property damage．If you’d like to learn more about the StarChase system，Popular Mechanics has just published a good article about it．There’s also plenty more information available at the company’s website．When the GPS bullet sticks to the escaping robber’s car，the police can________
| A．know the car’s condition |
| B．ensure the robber’s safety |
| C．play a fair game with the robber |
| D．know the car’s position and direction |
The GPS bullets could help save lives mainly because________．
| A．the bullets won’t hurt people |

Although the United States covers so much land and the land produces far more food than the present population needs，its people are by now almost entirely an urban society. Less than a tenth of the people are engaged in agriculture and forestry(林业), and most of the rest live in or around towns，small and large．Here the traditional picture is changing: every small town may still be very like other small towns，and the typical small town may represent a widely accepted view of the country，but most Americans do not live in small towns any more. Half the population now lives in some thirty metropolitan areas(1arge cities with their suburbs, of more than a million people each—a larger proportion than in Germany or England，let alone France). The statistics(统计)of urban and rural population should be treated with caution because so many people who live in areas classified as rural travel by car to work in a nearby town each day. As the rush to live out of town continues，rural areas within reach of towns are gradually filled with houses, so that it is hard to say at what moment a piece of country becomes a suburb. But more and more the typical American lives in a metropolitan rather than a small town environment．If now America has 250 million people．how many of them are engaged in agriculture and forestry?
| A．About 25 million |
| B．More than 25 million |
| C．Less than 25 million |
| D．Less than 225 million |
Which of the following four countries has the smallest proportion of people living in metropolitan areas?
| A．United States | B．Germany | C．France | D．England |
What’s the meaning of the word“metropolitan”in the middle of the passage?
| A．Of a large city with its suburbs | B．Of small and large towns |
| C．Of urban areas | D．Of rural areas |
Why don’t birds get lost on their long migratory (迁居的) flights? Scientists have puzzled over this question for many years. Now they’re beginning to fill in the blanks.
Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly mainly by night? Tests with artificial stars have proved conclusively that certain night-flying birds are able to follow the stars in their long-distance flights.
One such bird, a warbler(鸣禽) , had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird’s cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the direction of the make-be-live stars caused a change in the direction of his flight. Scientists think that warblers, when flying in daylight, use the sun for guidance. But the stars are apparently their main means of navigation (导航). What do they do when the stars are hidden by clouds? Apparently, they find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it’s too dark to see these, the warblers circle helplessly, unable to get their direction.The reasons why birds don’t get lost on migratory flights__________.
| A．have been known to scientists for many years |
| B．are known by everyone |
| C．have only recently been discovered |
| D．will probably remain a mystery |
Warblers migrate__________.
| A．from North America to South America |

| D．when they are freed from their cages |
When the stars are hidden by clouds, warblers find their way by__________ .

| B．jump to conclusions |
| C．find a law and then investigate（调查） |
| D．are disappointed by the habits of animals |

When a rather dirty, poorly dressed person kneels at your feet and puts out his hands to beg for a few coins, do you hurry on, not knowing what to do, or do you feel sad and hurriedly hand over some money? What should our attitude to beggars be? There can be no question that the world is full of terribly sad stories. It must be terrible to have no idea where our next meal is going to come from. It seems cruel not to give some money to beggars.
Certainly, most of the world’s great religions order us to be open-hearted and share what we have with those less fortunate than ourselves. But has the world changed? Maybe what was morally（道德方面）right in the old days, when one knew exactly who in the village had suffered misfortune and needed help, is no longer the best idea. Quite a few people will not give to beggars. Let us look at their arguments.
First, some believe that many city beggars dress up on purpose to look pitiable and actually make a good living from begging. Giving to beggars only encourages this sort of evil（恶行）.
Secondly, there is the worry that the money you give will be spent on beer, wine or drugs.
Thirdly, there is the opinion that there is no real excuse for begging. One might be poor, but that is no reason for losing one’s sense of pride and self-dependence.
There is an opinion that the problem should be dealt with by the government rather than ordinary people. Some people think the local government department should help the beggars
It is hard to come to any final conclusion: there are various cases and we must deal with them differently. A few coins can save a life in some situations, and even if the money is wasted, that does not take away the moral goodness of the giver.What is mainly discussed in the passage?
| A．Moral deeds of people. |
| B．Arguments on giving to beggars. |
| C．Moral goodness of the giver. |
| D．Religious activities of the church. |
What can we infer from the underlined sentence “But has the world changed?” in Para.2 ?
| A．People no longer know who suffers misfortune in the village. |
| B．Some people will not do what was morally right in the past. |
| C．We don’t meet with those who need help any more. |
| D．Now it is the government’s duty to help the beggars. |
Which of the following is NOT mentioned in the passage?
| A．Some people dress up to pretend to be beggars. |
| B．Some beggars have no excuse for begging. |
| C．Some beggars use the money to buy drugs. |
| D．Some beggars need money for their children’s schooling. |
In the last paragraph, the writer thinks that it is hard to come to any final conclusion, because________.
| A．there is so much money wasted |
| B．there are so many beggars |
| C．the cases can be so different |
| D．there are so many different arguments |
Recently Dr. Cleiman has proved that everyone has a daily energy cycle. During the hours when you labor (work) through your work, you may say that you are “hot”. That is true, the time of day when you feel most energetic is when your cycle of body temperature is at its peak (顶峰). For some people the peak comes during the forenoon (上午前). For others it comes in the afternoon or evening. No one has discovered why this is so.
Much family quarrelling ends when husbands and wives realize what this energy cycle means and which cycle each member of the family has.
You cannot change your cycle, but you can learn to make your life fit it better. “Habits can help,” Dr. Cleiman believes. If your energy cycle is low in the morning but you have an important job early in the day, rise before your usual hour, and then you will work better at your low point.
Get off to a slow start which saves your energy. Get up with a lazy yawn(哈欠) and stretch(伸展). Sit on the edge of bed before putting your feet on the floor. Avoid the troublesome searching for clean clothes by laying them out the night before.Dr. Cleiman did not explain in the passage ___________.
| A．how people can make their life fit their cycle |
| B．whether everyone has a daily cycle or not |
| C．why people have their energy cycle at different times |
| D．what will happen in the family if the couple fail to realize which cycle each member has |
For what reason may husbands and wives quarrel with each other?
| A．Either of them gets up late in the morning. |
| B．Husbands and wives have different cycles of energy. |
| C．Either of them wants to change the cycle of the other’s. |
| D．They do not know which cycle they themselves have. |
According to the passage, ____________.
| A．one works better at one’s peak energy point |
| B．if you know your cycle you can change it to fit your life. |
| C．whenever you feel hot, your energy cycle reaches the highest |
| D．your energy cycle must be in the morning if you can get up early |
Which of the following can save your energy in the morning?
| A．Getting up late. |
| B．Jumping out of bed as quickly as possible. |
| C．Looking for clean clothes. |
| D．Sitting for a while before getting out of bed. |
