5.根据以下资料，回答82-85题。 　　Can animals be made to work for us? Some scientists think that one day animals may be trained to do a number of simple jobs that are now done by human beings. 　　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.82 What made scientists think animal can be made to work for us one day?

6.Passage OneOceanography has been defined as "The application of all sciences to the study of the sea.Before the nineteenth century scientists with an interest in the sea were few and far between. Certainly Newton considered some theoretical aspects of it in his writings, but he was reluctant to go to sea to further his work.For most people the sea was remote, and with the exception of early intercontinental travelers or others who earned a living from the sea, there was little reason to ask many questions about it, let alone to ask what lay beneath the surface. The first time that the question"What is at the bottom of the oceans?" had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed. The engineer had to know the depth profile (起伏形状) of the route to estimate the length of cable that had to be manufactured.It was to Maury of the US Navy that the Atlantic Telegraph Company turned, in 1853, for information on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings (测水深) were taken to investigate the depths of the North Atlantic and Pacific Oceans. Later, some of his findings aroused much popular interest in his book The Physical Geography of the Sea.The cable was laid, but not until 1866 was the connection made permanent and reliable. At the early attempts, the cable failed and when it was taken out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in deeper parts of the sea.Within a few years oceanography was under way. In 1872 Thomson led a scientific expedition ( 考察), which lasted for four years and brought home thousands of samples from the sea. Their classification and analysis occupied scientists for years and led to five-volume report, the last volume being published in 1895.It was__________that asked Maury for help in oceanographic studies.

7.根据以下资料，回答66-69题。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.68 What is true to the fact in America?

The environment affects the way people interact.To examine this conclusion,two researchers"decorated"three rooms:One room was refurnished to look ugly.The second room was intended to look average.The third room was designed to be beautiful.Individuals were then asked to sit in one of the three rooms and rate several pictures of people's faces.The resultsindicated that the environment has a significant effect on the way peoplerated the faces.Subjects in the beautiful room gave the pictures higher rates than did subjects in the ugly room. In addition,subjects in the ugly room found the task more unpleasant and boring than did subjects in the beautiful room.Subjects assigned to the ugly room attempted to leave sooner than did subjects assigned to the beautiful room.

Color is one environmental factor that can affect your mood and even your ability to concentrate.One researcher concluded that the most pleasant colors,listed in order of preference,were blue,green,purple,red and yellow.The colors listed from most to least arousing were red,orange,yellow,violet,blue,and green.

Lighting also affects behavior.Elegant restaurants with dim lighting create a mood ofintimacy(亲密）that encourages conversation.The bright lights of an office or classroom,on the other hand, arouse and stimulate thinking.

Room decoration,color,lighting,and even music and temperature all influence communication with others,but there is no all-purpose environment.The ideal environmentdepends on the task that will be performed as well as on the needs and expectations ofthosepresent.The same environmentalfactors that encourage lively conversation and dancing at a New Year's Eve party cannot be expected to create asereneclimate in which to study for final exams.3.What effect can dim lights of an eating environment bring about?（）

As recently as three decades ago, many Americans believed that using credit was an unwise and dangerous way to pay for what they bought. Some even thought that owing money to a store or a credit company was something to be ashamed of. Good citizens, they believed, always bought what they wanted with real money and they paid the full

price immediately.

Today, however, all that has changed. Credit, as some observers have noted, has become a way of life in the United States. More and more Americans now are depending on those small pieces of plastic, credit cards, to pay for large purchases such as televisions, record players or furniture. Many people today would consider it unusual not to use a credit card to pay for a costly restaurant dinner, a hotel room or an airline trip. And there are some situations in which

Americans must have credit cards. If they want the temporary use of a car, for example, they first must give the car rental company the number of their credit card. That number is considered a guarantee that they will return the car and pay for using it.

Credit cards offer two major services to Americans. First of all, they are easier and safer to carry than large amounts of money. Second, they permit people to borrow, to have the immediate pleasure of owning something, even if they do not have enough money to pay for it at the time. With credit cards people pay for goods or services at the end of each month instead of when they buy them. And when the time does come to pay, most credit cards offer people a

choice. They can pay all of what they owe for the month or they can just pay usually between 5 and 10 percent of what they owe.Why does the car rental company ask for the credit card number?

19.As we recently discovered，there is a Stepmother’s Day，though it is not on any official holiday calendar.So，it would be safe to assume that there is a similar day for stepdads，too.Right? Well，it depends on what you read.A Google search brought up posts that say，for example，“It’s on father’s day--father’s day is for fathers，step—fathers and people who are like fathers to you-it’s a day for making father figures feel special.”Further searching found a Stepfather’s DayFacebook page that says，“The unofficial Stepfather’s Day is the fourth Sunday of June.”Unfortunately，as of the publishing of this article，only 30 people have “liked” the page.Considering that studies show 3.3 million men，or 11.1%of U.S.fathers，live with at least one stepchild，that’s only a drop in the ocean.It’s interesting to note that there is a National Grandparents’ Day.President Jimmy Carter signed it into law in 1978.Law! While grandparents are undoubtedly special people in our children’s lives，they are often seen as the most loving family members.But what about the stepparents? The stepparents are the ones who are often the outsiders，the ones who have to endure the hurtful “You’re not my dad!” or “You’re not my mom!” And yet they never give up.They do their best to overcome the inherent challenges of stepparents and be role models for their stepchildren.These unsung(未被颂扬的)family heroes deserve “official” days of honor.Perhaps if we are loud enough，President Obama，who had a stepfather himself，will sign into law NationalStepmother’s Day and National Stepfather’s Day.Are you with me? Follow me and get your voice heard.How cool it would be if we could make this happen!What is the reason for setting an official holiday for stepparents?
