(A)
The basenji is a central African hunting dog. It comes from a country called Chad, which is north of the Central African Republic. The basenji was well—known as the "silent dog" because for centuries no basenjis has ever been known to bark . Then at a dog show in London in 1953, a basenji actually barked.
As well as being clever, basenjis are known for their natural courage and are still popular hunting dogs in Africa. But in America people keep them mainly because they are gentle and full of fun. The basenji has an unusual habit, it washes itself all over like a cat. It is a middle—sized dog, 16 or 17 inches high from the shoulder. It weighs about 20 pounds. A basenji's coat is short and silky. It may be brown, white, or gold , or a mixture of these three colours.
56. Basenjis were first found .
A. in Africa, Europe and America B. in both Africa and America
C. in central Africa D. in North Africa
57. What made Basenjis so special?
A. They were funny enough to make people laugh.
B. One of them barked at a dog show in London.
C. They were a true friend of man.
D. They were born quiet dogs.
58. In what way are basenjis like cats?
A. They make gentle sounds instead of barking.
B. They are fond of people and look like cats.
C. They clean themselves all over.

Any observant person has noticed that a wild animal will allow a man or other potential enemy to approach only up to a given distance before it flees. “Flight distance” is the term used for this interspecies spacing. As a general rule, there is a positive relationship between the size of an animal and its flight distance—the larger the animal, the greater the distance it must keep between itself and the enemy. An antelope will flee when the enemy is as much as five hundred yards away. The wall lizard’s(壁虎) flight distance, on the other hand, is about six feet. Flight is the basic means of survival for mobile creatures.
Critical distance apparently is present wherever and whenever there is a flight reaction. “Critical distance” includes the narrow zone separating flight distance from attack distance. A lion in a zoo will flee from an approaching man until it meets a barrier that it cannot overcome. If the man continues the approach, he soon penetrates(进入) the lion’s critical distance, at which point the cornered lion turns back and begins slowly to stalk (逼近) the man.
Social animals need to stay in touch with each other. Loss of contact with the group can be fatal(致命的) for a variety of reasons including exposure to enemies. Social distance is not simply the distance at which an animal will lose contact with his group—that is, the distance at which it can no longer see, hear, or smell the group—it is rather a psychological distance, one at which the animal apparently begins to feel anxious when it goes beyond its limits.
Social distance is not always rigidly(刻板的) fixed but is determined in part by the situation. When the young of apes and humans are mobile but not yet under control of the mother’s voice, social distance may be the length of her reach. When added control is needed because of danger, social distance shortens. To show this in man, one has only to watch a family with a number of small children holding hands as they cross a busy street..
Which of the following is the correct explanation of “Flight Distance” in paragraph 1?
| A．Distance between animals of the same species before fleeing. |

One of Lewis Gordon Pugh’s first big attempts to put his cold-water skills to the test nearly ended in disaster. On a one-mile swim in Antarctica in December 2005, just yards from the finish, his body began to give in. The temperature inside his thigh muscle dropped to 87.8 degrees, the lowest ever measured in him. He was completely at the limits of his ability.
Despite what he called the “grueling (折磨人的)” Antarctic swim, Pugh scheduled an even more fearsome test for himself at the North Pole. Stepping off the way of the Russian icebreaker that had crunched(咯吱作响的穿过) through floating sea ice for five days to take him to the North Pole, Pugh walked across the ice to a pool of open water over one mile long and two and a half miles deep. The sea temperature was 29 degrees, only a little above the freezing point of salt water.
Pugh quickly took off his padded clothes. In only his bathing suit and cap, his skin already pink, he walked to the water’s edge. “The only place I’m getting out is at the end,” he told himself. Then he removed his earphones and dived in.
The pain was immediate. His entire body felt on fire. The doctor kept pace with him in a boat. Through iced-up goggles(护目镜), Pugh could see the armed guards keeping watch for bears.
His friend Becker had broken down the huge task into manageable parts, each one marked by a flag planted in the ice that represented a friend, family member, or teammate. Fog started to roll in as Pugh headed for the final marker, the flag of Great Britain. He imagined his late father standing beside it--- the man who had done so much to give him an interest in adventure. Then Pugh drove himself to the finish. After 18 minutes 50 seconds in the water, his body was not even hypothermic(体温过低的)..

Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn't matter where you live---in the middle of a modern city or a faraway village---the chances are that you’ll be disturbed by jet planes, transistor radios, oil-powered engines, etc. We seem to be getting used to noise, too. Some people feel quite lonely without background music while they’re working.
Scientific tests have shown that total silence can be a very frightening experience for a human being. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums(耳鼓). The noise level in some discos is far above the usual safety level for heavy industrial areas.
One recent report about noise and concentration suggested that although a lot of people say that any noise disturbs their concentration, what really influences their ability to concentrate is a change in the level of noise. It goes on to say that a background noise which doesn't change too much (music, for example) may even help people to concentrate..
According to this passage, the noise pollution______.
| A．has become the worst in the countryside |
| B．has become better in big cities |
C．has spread from cities to villages |
| D．has been controlled in modern cities |
.
What does background music refer to?
| A．Music played while people are working. |
| B．Music played in the backyard. |
| C．Noise that continues while you’re listening to other noises. |
| D．Music used to help people to concentrate. |
.
. Some people have their hearing harmed______.
| A．while listening to pop music | B．in complete silence |
| C．when speaking loudly | D．while watching TV |
Terraforming (Earth-forming) other planets, also known as planetary engineering (行星工程), seems like a task still centuries away for mankind to accomplish. However, it is a vigorous topic that attracts both popular and scientific interest. Why should the possibility of terraforming other planets be studied when it may be centuries before we know enough to even decide if it’s a good idea?
Mankind is getting more and more hard facts about other planets. The atmosphere of Venus has been explored; robots have surveyed the surface of Mars; Mercury, Jupiter and Saturn have been studied by spacecraft. Speculations have been answered; new questions have been raised, and enough hard data is right now becoming available to allow us to make the first attempt of planetary engineering.
In the past, people with excellent ideas about terraforming have kept them to themselves, or buried them in a desk drawer because they did not realize that anyone else was interested. But now, a wide circle of people has begun to do this kind of work. For instance, NASA funded a project on transforming Mars.
There are several strong reasons which demand that the possibilities of terraforming be studied carefully. First, it’s an exciting idea of a possible future for human beings. Such thinking has a valuable role in providing options for our future directions. Secondly, the techniques of terraforming will also help contemporary technologies in weather and climate control. Thirdly, such study may assist us in detecting any possible existence of extraterrestrial intelligence (SETI, The Search for Extraterrestrial Intelligence, 地外文明搜索) and alien (异己的) civilizations on other planets.
Though the mission is far beyond our reach at the moment, we should at least keep our options open. Through debate and study on this subject, the possibility of rebuilding other planets to make them suitable homes for people may come true some day in the future..
. According to the context, what’s the meaning of the word “speculation” in paragraph 2?
| A．The act of discussing something with a group of people. |
| B．The act of studying and researching. |
| C．The act of guessing without knowing all the facts about something. |
| D．The acting of writing letters to a certain organization. |
.
Why did people keep the idea of terraforming to themselves in the past?
| A．They thought no one else would show interest in the idea. |
| B．They gradually came to find the idea crazy. |
| C．They thought the idea would never come true. |
| D．They had few resources for further study on this topic. |
.
. Which is NOT the reason to support the study of terraforming?
| A．Even if we don’t succeed in terraforming, such study may help us to better understand technologies such as climate and weather control. |
| B．Such study may explore a new direction of development for human beings. |
| C．Such study may enable us to find the lives on other planets. |
| D．As the resources on Earth are being drained, it’s very urgent to study how to migrate (迁移) to other planets。 |
.
What’s the main idea of the article?
| A．It’s highly possible that terraforming other planets will come true so we should increase investing in this program. |
| B．Even if the idea of terraforming other planets may take centuries to realize, we have many reasons to support such studies. |
| C．Terraforming other planets is the best option for human being’s future. |
| D．More and more people are taking planetary engineering as their occupation. |
One of our biggest fears nowadays is that our kids might some day get lost in a “sea of technology” rather than experiencing the natural world. Fear – producing TV and computer games are leading to a serious disconnect between kids and the great outdoors, which will change the wild places of the world, its creatures and human health for the worse, unless adults get working on child’s play.
Each of us had a place in nature we go sometimes, even if it was torn down. We cannot be the last generation to have that place. At this rate, kids who miss the sense of wonder outdoors will not grow up to be protectors of natural landscapes. “If the decline in parks use continues across North America, who will defend parks against encroachment（蚕食）?” asks Richard Louv, author of Last Child in the Woods.
Without having a nature experience, kids can turn out just fine, but they are missing out a huge enrichment of their lives. That applies to everything from their physical health and mental health, to stress levels, creativity and cognitive（认知的）skills. Experts predict modern kids will have poorer health than their parents—and they say a lack of outside play is surely part of it; research suggests that kids do better academically in schools with a nature component and that play in nature fosters（培养）leadership by the smartest, not by the toughest. Even a tiny outdoor experience can create wonder in a child. The three – year – old turning over his first rock realizes he is not alone in the world. A clump of trees on the roadside can be the whole universe in his eyes. We really need to value that more.
Kids are not to blame. They are over – protected and frightened. It is dangerous out there from time to time, but repetitive stress from computers is replacing breaking an arm as a childhood rite（仪式）of passage.
Everyone from developers to schools and outdoorsy citizens, should help regain for our kids some of the freedom and joy of exploring, taking friendship in fields and woods that cement（增强）love, respect and need for the landscape. As parents, we should devote some of our energies to taking our kids into nature. This could yet be our greatest cause..
