根据以下资料，回答以下题。 　　On television all over the world there are programmes about the work of the police．They are popular because they are usually very exciting．In London there is a television programme called"Police Five "--because it is on for five minutes once a week．A television reporter, Shaw Taylor, talks about crimes in the London area．He asks for public help．The police station needs the help of ordinary people because sometimes you or I have information that can be useful to the police.
　　Shaw Taylor shows pictures of paintings, jewellery (珠宝) and other things which thieves stole during the week．Sometimes he shows the car that the thieves escaped in．When people see men or things on the television programme which they may remember, they can tell the police where they saw them．With their help the police may catch more criminals.
　　Sometimes the police find a car or some money．Shaw Taylor shows them on television．The owners sometimes see them．Then they can telephone the police and say, "Thank you very much-- that's mine!"

根据以下资料，回答以下题。 　　The traffic lights were red when the driver reached them．To the surprise of his passenger, the ear did not slow down．Unexpectedly the passenger was thrown forward in the vehicle as the driver put on his brakes at the last moment．The car stopped just in time.
　　"Sorry, I didn't notice the light．I thought it was green until I saw that it was the top light which was shining."
　　This strange story is quite true．About ten men in every hundred are color blind in some way; women are luckier-- only about one in two hundred suffers from color blindness.
　　In some cases, a man may not be able to see deep red．He may think that red, orange and yellow are all the same as green.
　　People often like one color more than others．Blue is the color of the sky and sea．Green makes us think of fields and trees．Red is the color of blood and makes some people think of danger．Black is the color of night．In the dark we cannot see what is around us so we are sometimes afraid of the unknown and do not like black as a color.

根据以下资料，回答以下题。 　　Of all Barry H．Landau's anecdotes about his friendships with presidential dogs, perhaps the best is the one about the time the Clinton White House called to postpone his play-date with Buddy．
　　Yes, Landau is both human and an adult, a 60-year-old author, presidential historian, former White House protocol officer and memorabilia collector．But so enamored is he of dogs, and so well connected to a succession of presidents, that he had an appointment for a South Lawn romp one day with Buddy, Bill Clinton's Labrador retriever (拉布拉多犬) .
　　Logistics got in the way, though, and hence Clinton secretary Betty Currie's apologetic voice mail left at the Smithsonian Institution, where Landau was doing research: "I'm sorry, but we'll have to reschedule Mr．Landau's play-date with Buddy."
　　Not surprisingly, this is a happy week for Landau, with the new Obama family dog, Bo, joining a White House tradition that dates to George Washington．It's one that Landau feels is invaluable to a presidency.
　　"Having a dog just humanizes a president," he says．"It completes the picture．It's something people can relate to."
And Landau has related to the best of them．He's known about 25 White House dogs since the Eisenhower administration．Among the presidential-pooch memorabilia in his Manhattan apartment are matching orange inaugural dog coats worn by LBJ's twin beagles (小猎犬) , Him and Her, and a photo of Landau kissing Clipper, JFK's German shepherd.

根据以下资料，回答以下题。 　　Every year gray whales migrate from the Bering Sea in Alaska to the Baja Peninsula in Mexico.
　　Eleven gray whales have died in the San Francisco Bay in the last three weeks．No one knows why the whales are dying.
　　Last year 270 whales died along the whales' migration route．Many people think starvation is the cause．This year the dead whales seem to have more blubber (fat) on them.
　　Twenty years ago, the gray whale was listed as an endangered species.
　　Some scientists think that the larger number of whales makes it hard to find enough food．More whales create more pressure on the food supply, a supply that some scientists say may have dwindled as a result of the warm waters of El Nino.
　　Most of the whales have been dead for many days before they are found and studied．This makes it hard to find the reason for death.
65 whales have been seen in the San Francisco Bay Area this year compared to 17 last year．The whales could be dying from many diseases, but it may be over-population．

根据以下资料，回答以下题。 　　Key James, Secretary of Health and Human Resources in the Virginia State government, loves to turn the tables on those who don't think it's possible to be middle-class, conservative, educated and still be truly black．Once, during an abortion debate, a woman in the audience angrily told James she was so middle-class she didn't have a clue about real African American life．"If you understood what these women go through," the woman said, "you would realize that abortion is their only choice."
　　James then asked the woman to consider a poor black mother on welfare．She already has four children and an alcoholic husband who has all but abandoned the family．Now she discovers another child is on the way．"How would you counsel that woman?" asked James.
　　"Have an abortion," the woman responded．"That child would have a very poor quality of life."
　　"I have a vested interest in your answer," James said．"The woman I described was my mother．I was the fifth of six children born into poverty．And, in case you're interested, the quality of my life is just fine!"

　　We first think of the traditional or nuclear family．This is a two-generation family, the father and the mother and their own children．Most couples wanted to have four children, two boys, two girls.
　　Some nuclear families, however, may add one or more grandparents to come to live with them, that is three generations．This kind of family with grandparents, parents, and grandchildren is called an extended family．This family type was not very common during the later half of the twentieth century, but it's becoming more common now as an elderly grandparent moves in to live with a son or daughter．This is more possible now that American homes have become larger．What is interesting, however, is that after the grandchildren move out of the home and start their own families, this extended family shrinks back to a nuclear family, with just two generations again living together, a grandparent and parents, with the grandchildren coming only for occasional visits．
　　Now, the fatherless or motherless family is one kind of what we call a single-parent family．In the fatherless family it's just the mother and her children．As I said, this can be the result of the husband's death, of an unmarried mother, of a separation or divorce．There are also a growing number of motherless families--where the father raises the children, for any of the same reasons．A motherless family may also be fatherless, but still a family with one adult．This is becoming more common in the big cities where a grandmother will raise her daughter's children while the daughter goes elsewhere to work.
　　One other new kind of family is becoming increasingly more common．A single parent with one or more children will marry again．Perhaps the other parent is also a single parent．Together they will start what is called a blended family, which blends together or combines the children from two other families.

根据以下资料，回答以下题。 　　First, the spotted owl was threatened by logging in the Pacific Northwest．Now it's in danger from a new enemy, the barred owl．Barred owls have been moving to the Northwest from the eastern part of the United States．Stan Sovern has studied spotted owls．Now when he calls for spotted owls, barred owls are starting to appear．Sovern threw a mouse on the ground, and a barred owl grabbed it.
　　Scientists have learned that spotted owls start to vanish when barred owls come．Some barred and spotted owls have mated and produced hybrid babies．One spotted owl was killed by a barred owl.
　　Professor Ned K．Brown of the University of California-Berkeley says, "In some areas of Washington, the barred owls moved into very dense, deep woods．The same kind of woods that arc opened up, or destroyed by logging, that adversely influences the spotted owls."
　　Ten years have passed since the federal government began protecting the spotted owl．Loggers were forced to limit logging on seven million acres of government land．No one is sure how the arrival of the barred owls will impact laws that protect spotted laws．The barred owls like to live in the deep forests where loggers like to cut down trees．The barred owls will likely keep migrating to the Northwest.

根据以下资料，回答以下题。 　　Years ago, a cigarette commercial asked if you were smoking more, but enjoying it less．That describes the way many of us live today．We are doing more, but enjoying it less．And when that doesn't work, we get the problem．In our extremely hurried search for satisfaction, we try stuffing still more into our days, never realizing that we are taking the wrong approach.
　　The truth is simple; so simple it is hard to believe．Satisfaction lies with less, not with more．Yet, we pursue the myth that this thing, or that activity, will somehow provide the satisfaction we so desperately seek.
　　Arthur Lindman, in his very effective book, "The Harried Leisure Class," described the uselessness of pursuing more．His research focused on what people did with their leisure time．He found that as income rose, people bought more things to occupy their leisure time．But, ironically, the more things they bought, the less they valued any one of them．Carried to an extreme, he predicted massive boredom in the midst of tremendous variety．That was more than twenty years ago, and his prediction seems more accurate every year.
Lindman of course, is not the first to discover this．The writer of Ecclesiastes expressed the same thought thousands of years ago．It is better, he wrote, to have less, but enjoy it more.
　　If you would like to enjoy life more, I challenge you to experiment with me．How could you simplify your life? What could you drop? What could you do without? What could you stop pursuing? What few things could you concentrate on?
　　The more I learn, the more I realize that fullness of life does not depend on things．The more I give up, the more I seem to gain．But words will never convince you．You must try it for yourself．

根据以下资料，回答以下题。 　　Some people do not like anything to be out of place; they are never late for work; they return their books on time to the library; they remember people's birthdays; and they pay their bills as soon as they arrive．Mr．Hill is such a man.
　　Mr．Hill works in a bank, and lives alone．The only family he has is in the next town: his sister lives there with her husband, and her son, Jack．Mr．Hill does not see his sister, or her family, from one year to the next, but he sends them Christmas cards, and he has not forgotten one of Jack's seventeen birthdays.
　　Last week Mr．Hill had quite a surprise．He drove home from the bank at the usual time, driving neither too slowly nor too fast; he parked his car where he always parked it, out of the way of other cars, and he went inside to make his evening meal．Just then, there was a knock at the door．He opened the door, to find a policeman standing on the door-step.
　　"What have I done wrong?" Mr．Hill asked himself．"Have I driven on the wrong side of the road? Has there been some trouble at the bank? Have I forgotten to pay an important bill?"
　　"Hello, Uncle," said the policeman, "My name is Jack."

　　They point out that at a circus, for example, we may see elephants, monkeys, dogs and other animals doing quite skillful things．Perhaps you have seen them on the television or in a film．If you watch closely, you may notice that the trainer always gives the animal a piece of candy or a piece of fruit as a reward．The scientists say that many different animals may be trained to do a number of simple jobs if they know they will get a reward for doing them.
　　Of course, as we know, dogs can be used to guard a house, and soldiers in both old and modem times have used geese to give warning by making a lot of noise when a stranger or an enemy comes near．But it may be possible to train animals to work in factories．In Russia, for example, pigeons which are birds with good eyesight, are being used to watch out for faults in small steel balls that are being made in one factory．When the pigeon sees a ball which looks different from others, it touches a steel plate with its beak．This turns on a light to warn people in the factory．At the same time a few seeds are given as a reward．It takes three to five weeks to train a pigeon to do this and one pigeon can inspect 3 000 to 4 000 balls an hour.
　　Apes have been used in America in helping to make cars, and scientists believe that these large monkeys may be one day gather crops and even drive trains.
