Koala bears as pets might be appealing to many of us. However, there are quite a few points to consider even before thinking of adopting one.
Koala bears are one of the most lovely Australian animals. In certain cases where the koala has been raised by hand, they have turned out to be quite affectionate pets. These people tied a piece of fur to a pillow and placed it beside a joey (a baby kola) as a substitute (替代物) for the mother koala. This trick seemed to work well with the baby koala. However, it is a known fact that human handling causes stress to koalas. In my personal opinion, this aspect clouds the fact that koala bears can be tamed (馴服).
In Australia the koala is a priority animal as far as conservation status assessment is concerned. It was hunted to near extinction (滅絕) for its fur. In fact the koala had been wiped out from South Australia in the 1920s. However, rehabilitation efforts have brought the animal back in the state. As for the Australia government, the koala is not a threatened animal, but the US government does list the koala as one.
Although they may live in 40 to 60 kinds of eucalyptus trees, they prefer only 10 to 14 specific kinds. Koalas sleep for most part of the day, which is about 16 to 18 hours, and for most of their waking hours all they do is eat. Koala bears eat the leaves of eucalyptus trees. A full-grown koala can eat almost 2 to 3 pounds of leaves in a day. Despite their slow movements and sweet look, koala bears can be vicious when hungry. Other than this, there are the stress caused to koalas due to human handling and the fights that start in koalas.
Almost everyone finds koalas lovely in the zoo. However, as far as having koala bears as pets is concerned, there are legal issues to consider. Other than that, being able to provide for its diet and habitat is another point that needs some attention before any law legalizing their adoption as pets is passed.

Everybody knows that colors are connected with certain feelings. For example, why do some people paint the walls of their rooms yellow and others pink? The same is true in stores. They want us to feel something when we look at their products.
Green, for example, tries to show the quality of a product: how good it is for us or for our environment. It also suggests that the product is healthier, has less fat and maybe fewer calories. Red, on the other hand is an aggressive color that is often used for packaging food. Red wants us to become hungry or thirsty. Purple is a kind of color that is often seen as royal. It indicates that it is something special. Producers use purple to show that something is of good quality. Blue is not very often found in food packaging because there are not very many foods that have a blue color.
Colors can also have different meaning in different cultures and countries. For example, while the color white is used in many Western countries to represent purity and innocence, it is seen as a symbol of mourning in many Eastern countries. The Egyptian pharaohs(法老) wore white crowns. A white sale is a sale of sheets, towels, and other bed and bath items. A white flag is the universal symbol for truce(休戰(zhàn)). A white elephant is a rare, pale elephant sacred(神圣的) to the people of India, Thailand, Burma, and Sri Lanka. In these countries, something that is a white elephant is either a possession that costs more than it is worth to keep or an item that the owner doesn’t want but can’t get rid of.
Consumers are aware that certain foods must have certain colors. When Pepsi brought out a crystal clear cola in 1992, it thought that consumers would buy it because clear meant pure and healthy. After a few months Pepsi found out that a cola had to be dark-colored. Crystal Pepsi failed and the company pulled it off the market.
Advertising professionals often need to look at a product through the consumers’ eyes when choosing a color. The right packaging colors can truly improve the sales of a product but choosing a wrong color could end in failure.
【小題1】According to the passage, blue is rarely used in food packaging because ____.
| A．most consumers dislike it |
| B．it matches very few foods |
| C．it brings people low spirits |
| D．it doesn’t catch people’s eyes |
| A．a(chǎn) white flag | B．a(chǎn) white elephant |
| C．a(chǎn) white sale | D．a(chǎn) white crown |
| A．Pepsi’s success comes from failures |
| B．health is the main concern in drink making |
| C．crystal clear drinks can’t attract consumers |
| D．people have fixed ideas about products and colors |
| A．Colors in advertising |
| B．Colors in food packaging |
| C．Our everyday life and colors |
| D．Foods in different colors |

Scientific experiments can sometimes go wrong and when they do the results may range from the disastrous to the troubling. One such experiment took place in South America about fifty years ago. Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen.
The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country’s bees. He imported a very active type of African bee from Tanzania and mated (交配)it with the more easy-going native variety to produce a new kind of bees. The new bees worked harder and produced twice as much honey. It seemed that Professor Kerr, for that was the scientist's name, had a total success on his hands.www.zxxk.com
Then things began to go wrong. For some reason as yet unseen, but perhaps as a result of something in their environment, the new bees began to develop extremely attacking personalities. They became bad-tempered and easy to be angry, attacked the native bees and drove them from their living places.
But worse was to follow. Having taken over the countryside, the new bees, with their dangerous stings (叮) , began to attack its neighbors -- cats, dogs, horses, chickens and finally man himself. A long period of terror began that has so far killed a great number of animals and about 150 human beings.
This would have been bad enough if the bees had stayed in Brazil. But now they are on the move, heading northwards in countless millions towards Central and North America, and moving at the alarming speed of 200 miles a year. The countries that lie in their path are naturally worried because it looks as if nothing can be done to stop them.
【小題1】 The results of the South American experiment .
| A．a(chǎn)re not yet certain | B．have proved to be wrong |
| C．have caused a serious trouble | D．a(chǎn)re not important |
| A．make African bees less active |
| B．make Brazilian bees more easy-going |
| C．increase the number of bees in Brazil |
| D．increase the amount of honey in Brazil |
| A．Their production of honey. | B．Their living environment. |
| C．Their hard work. | D．Their bad temper. |
| A．the bees have been driven to Central and North America |
| B．the bees must be stopped from moving north |
| C．the bees may bring about trouble in more countries |
| D．the bees prefer to live in Brazil |

We probably all know people, either at work or in our personal lives, who are really good listeners. No matter what kind of situation we’re in, they always seem to know just what to say and how to say it so that we’re not offended(被冒犯) or upset. We probably also know people who are masters at managing their emotions(情緒). They don’t get angry in stressful situations. Instead, they have the ability to calmly look at a problem and find a solution. They take criticism(批評) well, and they know when to use it to improve their performance.
People like these who have a high degree of emotional intelligence, or EI(情商). They know themselves very well, and they’re also able to sense the emotional needs of others.
As more and more people accept that emotional intelligence is just as important to professional success as technical(專業(yè)的) ability, companies are increasingly using EI when they hire and promote(提拔) someone. For example, one large cosmetics (化妝品) company recently changed their hiring process for salespeople to choose candidates(被選的人) based on emotional intelligence. The result? Salespeople hired with the new system have sold, on average, $91,000 more than salespeople selected under the old system.
Emotional intelligence is the ability to recognize your emotions, understand what they are telling you, and realize how your emotions affect people around you. Emotional intelligence also involves your perception (洞察力) of others: when you understand how they feel, this allows you to manage relationships more effectively.
People with high emotional intelligence are usually successful in most things they do. Why? Because they are the ones that others want on their team. When people with high EI send an email, it get answered. When they need help, they get it. Because they make others feel good, they go through life much more easily than people who are easily angered or upset.
The good news is that emotional intelligence can be taught and developed. Many books and tests are available to help you determine your current EI, and identify where you may need to do some work.
【小題1】According to the passage, we’re all probably impressed by people who _____.
| A．a(chǎn)re ready to help others |
| B．a(chǎn)re very successful in their lives |
| C．have high emotional intelligence |
| D．know how to control their temper |
| A．stress the importance of emotional intelligence |
| B．speak highly of its new salespeople |
| C．show its effective hiring system |
| D．explain what improvements it has made |
| A．your emotions | B．people around you |
| C．effective relationships | D．your opinions of others |
| A．They are usually good speakers. |
| B．They are born to be sensitive and intelligent. |
| C．They don’t get angry in any situation. |
| D．They can understand others’ feelings well. |
| A．What emotional intelligence is. |
| B．How emotional intelligence can be improved. |
| C．Many books on emotional intelligence. |
| D．More people with high emotional intelligence. |

The common cold is the world's most widespread illness, which is plagues(疫病) that flesh receives.
The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses(病毒) passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.?
During the First World War soldiers who spent long periods in the trenches(戰(zhàn)壕), cold and wet, showed no increased tendency to catch colds.?
In the Second World War prisoners at the notorious Auschwitz concentration camp(奧斯維辛集中營), naked and starving, were astonished to find that they seldom had colds.?
At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.?
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains—taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.?
No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is to relieve the symptoms(癥狀).
【小題1】The writer offered _______ examples to support his argument.
| A．4 | B．5 | C．6 | D．3 |
| A．The Eskimos do not suffer from colds all the time. |
| B．Colds are not caused by cold. |
| C．People suffer from colds just because they like to stay indoors. |
| D．A person may catch a cold by touching someone who already had one. |
| A．they are working in the isolated Arctic regions |
| B．they are writing reports in terribly cold weather |
| C．they are free from work in the isolated Arctic regions |
| D．they are coming into touch again with the outside world |
| A．the fallacy about the common cold |
| B．the experiments on the common cold |
| C．the reason and the way people catch colds |
| D．the continued spread of common colds |

It is often said that man has become the enemy of our planet. This is no exaggeration(夸張), for reports show that man’s greed has done much to destroy the earth. Man, in his greedy desire for financial growth, has polluted the air, land and water, and has robbed our valuable natural resources. Man’s industrial plants pour out poisonous waste that pollutes the sea and puts life in the sea under the threat of dying out; at the same time, they release alarming amounts of carbon dioxide, chlorofluorocarbons (CFCs) and other pollutants. Small wonder that the air now is much warmer and more impure than ever before.
Of course, this is not just because of man’s greed—it is man’s pressing need as well. For instance, in developing countries, huge financial foreign debts have forced governments to approve the cutting of forests for agriculture or ranching. As a result, forests are cut down just to meet man’s immediate needs.
Perhaps unknowingly，man has changed the make-up of the earth's atmosphere. Scientific studies have shown that CFCs used in refrigerators and industrial cleaners are fast destroying the ozone layer—a protective layer in the atmosphere that protects us against the harmful effects of the sun’s ultraviolet (紫外線)rays. In fact, documented reports have shown a terrible fact that there are “holes” in the ozone layer over the Antarctic. And they appear to be expanding.
Faced with these environmental problems, world leaders have shown deep concern. The UN Environmental Programme (UNEP) has arranged international agreements like the Vienna convention of 1985 and the Montreal Protocol of 1989 to preserve the ozone layer by controlling the production, use and trade of destructive chemicals.
There may be some doubt as to how effectual these agreements may be, given that some countries still maintain an “I-don’t-care” attitude. Their attitude is probably due to their failure to grasp the importance of the problem. Then, there is no doubt that environmental education on an international scale（規(guī)模）is greatly needed, so that all countries, great and small—the “haves” and the “have nots”—may realize their responsibilities for our planet.
In the meantime, the UNEP seems to have taken steps in the right direction, and it is hoped that in the not so distant future, all nations of the world will join hands in saving mother earth.
【小題1】Which of the following is a reason for the cutting and burning of forests?
| A．To build houses for more population. | B．To have land for agriculture. |
| C．To export trees to other countries. | D．To build industrial plants. |
| A．man’s research activities | B．the greenhouse effect |
| C．the ultraviolent | D．harmful chemicals |
| A．They don’t want to put their lives in danger. |
| B．They just don’t know how to solve the problem. |
| C．They haven’t realized the seriousness of the problem. |
| D．They don’t want to break their international commitment. |
| A．Hopeful. | B．Unconcerned | C．Doubtful | D．Objective |

Black Box
You never see them, but they're with you every time you fly. They record where you're going,how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to resist almost any disaster makes them seem like something out of a comic (漫畫) book.They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to the Comoros Islands in the Indian Ocean on June 30, 2009, the black box is the best method for identifying what went wrong. So when a French submarine(潛水艇) discovered its homing signal five days later, it marked a huge step toward determining the cause of the disaster in which 152 passengers were killed.
In 1958. Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first model for a black box, which became a requirement on all US commercial flights by 1960. Early models often failed to resist crashes, however, so in 1965 it was completely redesigned. That same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to be easier to see.
Modem airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help experts reconstruct the aircraft's final moments. The boxes can resist powerful force and temperatures up t0 2,OOOoF. They're also able to send out signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447 , which crashed near Brazil on June 1 , 2009 , are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.
【小題1】What can we leam about the black box from the passage?
| A．It helps an airplane function normally. |
| B．Its ability to avoid disasters is amazing. |
| C．It is necessary equipment on an airplane. |
| D．The idea for its design comes from a comic book. |
| A．the scene of the crash and the damage |
| B．data for analyzing the cause of the crash |
| C．the total number of passengers on board |
| D．homing signals sent by the pilot before the crash |
| A．make them easily identified |
| B．meet the international standards |
| C．caution people to handle them with care |
| D．distinguish them from the color of the plane |
| A．They have stopped sending homing signals. |
| B．They were destroyed somewhere near Brazil. |
| C．There is an urgent need for them to be restructured. |
| D．There is still a good chance of their being recovered. |

The World's Largest Insect .This giant insect can be used as a toy.
A child ties one end of a string to a stick and the other end around the "neck" of an insect. Holding the stick, the child lets the insect go. With a loud whirring sound, the insect takes off, pulling the string in a large curve over the child's head. The child laughs as the stick jumps around. The child is African, and the toy is the African Goliath beetle, the largest insect in the world.
The Goliath is a true insect because it has six legs and a body that is divided into three parts. Like all beetles, it has two pairs of wings. The front pair are thick and stiff and protect the back pair, which are soft. It is these soft back wings that make the beetle fly forward. They also cause the loud whirring sound the beetle makes when it flies. To steer, the beetle twists and turns its legs the same way you steer a bike by turning its front wheel.
African children often use the Goliath beetle as a toy. Although it is over 15 centimeters long, it is quite harmless.
【小題1】 The African Goliath beetle is _______.
| A．the world's largest insect |
| B．a(chǎn) toy used in many parts of the world |
| C．the only insect found in Africa |
| D．the world's smallest insect |
| A．a(chǎn) tool. | B．a(chǎn) toy. | C．harmfull insects. | D．Good animals. |
| A．makes a whirring sound when it flies | B．has both soft and hard wings |
