We need to make better use of our resources. In developing countries we have more than enough, if we are less wasteful in our ways. Fortunately, we can improve. The challenge lies not so much with ‘technical fixes’ but with our approach to our world around us. In the recent past we were in a “Wild West” economy, supposing that there would always be enough resources. Now we know there are no new Earth to explore and exploit; one image to illustrate this is to think of Earth as a spaceship, where most materials have to be recycled. For us, “moving on” will be a case of leaving behind the throwaway society and advancing to a conserver society.
To qualify as citizens of a conserver society, we must change traditional attitudes and thinking. We need to recognize that there is not very often such a thing as “waste”, rather, there are materials which sometimes end up in the wrong place. The change has already begun. The European steel industry reuses scrap（廢棄的）metal, resulting in an energy saving of up to 50% . Recycling a glass container saves only 18%; but, in parts of the United States, a citizen buying a bottle of soda or beer now pays a deposit against return of the empty bottle.
If all drink containers in the USA were to be reused, the annual saving would be 0.5 million tons glass, plus about 50 million barrels of oil used in production processes. In Japan, OPEC promoted an increase in recycling of raw materials from 16% to 48% in just five years. In Norway, the price of a new car includes a disposal cost element of about 100 dollars, redeemable（可換成現(xiàn)款的）when the junked car is turned in at an approved receiving center.
Major new businesses are trying to exploit waste chemicals and oil. The Chinese claim to reuse 2.5 million tons of scrap iron and at least one million tons of waste paper each year. In the main, the conserver society depends on the commitment of individuals. But they can be encouraged by government incentive(鼓勵(lì)) and punishment, which should apply at least as strongly to industry and other commercial interests.
73  Which of the following best expresses the meaning of “a conserver society” in the second paragraph?
A. A wasteful society.
B. A society which thinks of  ways of recycling waste materials.
C. A society which keeps everything.
D. A society which saves electricity.
74  In the last paragraph, the author suggests governments _______.
A. depends on individuals to find ways of conserving energy.
B. find ways of encouraging those industries and individuals who conserve energy and of punishing those who don’t.
C. depend on companies to find ways of saving energy and rewarding workers
D. help establish businesses that will exploit waste materials
75  In this passage the author _______.
A. explains that meaning of the “Wild West” economy
B. tells us what recycled materials are.
C. teaches us how to recycle materials.
D. recommend a change in our use of resources strongly

Did you ever wonder why leaves change colors in autumn, or how it happens? Here’s a quick explanation.
First of all, you’ve probably noticed that not all trees lose their leaves. There are two major types of trees: deciduous trees and evergreens. Evergreens keep their leaves and stay green all year long. The deciduous trees are the ones that lose their leaves each year.
In autumn, the days begin to get shorter. The sun is also lower in the sky at noon, which causes temperatures to be cooler. The combination of less sunshine and lower temperatures is what causes the deciduous trees to drop their leaves. In winter, deciduous trees “go to sleep”, sort of like a bear goes into hibernation.
Leaves are the food factories for a plant. Unlike animals，plants make their own food by taking energy directly from the sun. Plants do this by using a chemical in their leaves called chlorophyll.
Chlorophyll is green. During the spring and summer the leaves of a deciduous tree look green because there is a lot of chlorophyll there. In autumn, however, the sunshine becomes more  scarce and the leaves on the trees stop making new chlorophyll. As the old chlorophyll starts to break down, the green color of the leaf begins to go away.
You’ve probably also noticed that the leaves of different kinds of trees change different colors. The leaves of some trees turn yellow or orange, while the leaves of other trees turn bright red or purple. The different colors are caused by the different chemical reactions that are happening in the leaves.
For example, the leaves of some trees turn yellow when the chlorophyll breaks down. When the green chlorophyll goes away, a yellow pigment in the leaf becomes visible. The yellow pigment, called cartenoid, was already there during the summer, but is was not easily seen because there was too much green chlorophyll.
In other trees where the leaves turn red or purple a different chemical reaction takes place. In those leaves the chlorophyll also breaks down, but another chemical reaction takes place at the same time. Chemicals in the leaves, called starches, begin to change into chemicals called anthocyanins, which give the leaves their red and purple colors.
So next time you see the beautiful colors of autumn you will also know the science behind that beauty.
46.   What is the correct term for trees that lose their leaves in the autumn?
A. Evergreens       B. Deciduous        C. Cartenoids  D. Anthocyanins
47.   Which of the following is NOT mentioned as a cause of trees dropping their leaves?
A. A change in temperature   B. The amount of daylight available
C. Extra chlorophyll         D. Chemical changes in the leaves
48.   If there are 50 evergreens and 10 deciduous trees in a forest, in autumn what color are most of the leaves in the forest likely to be?
A. Green B. Red and purple
C. Yellow        D. not enough information to determine the answer
49.   Which of the following is only present in leaves during the autumn?
A. Chlorophyll       B. Starch C. Cartenoids        D. Anthocyanins
50.   Where would such an article mostly likely be published?
A. In a book                   B. In a primary school science text book
C. In a magazine for young people       D. All are equally likely

When did you see a polar bear ? On a trip to a zoo, perhaps ? If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These  “Polar Bears” are people who meet frequently in the winter to swim in freezing cold water. That day, the air temperature was 3 degrees. And the water temperature was a little higher. The members of the Polar Bear Club at Coney Island, New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group; this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February.
Doctors don’t agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body’s temperature drops so slow that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and the water tempreature is much greater in summer than in winter.
The Polar Bears themselves are satisfied with the benefits of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system (循環(huán)系統(tǒng)) because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and could not try cold-water swimming.
The main benefits of cold-water swimming are probably mental. The Polar Bears love to swim all the year round; they find it fun and relaxing. As one 70-year-old woman says, “When I go into the water, I pour my troubles into the ocean and let them float away.”
1. Doctors _________ .
A. have different ideas about the medical effects of cold-water swimming
B. believe swimming is helpful both in summer and in winter
C. enourage people to take part in cold-water swimming
D. point out the possible danger of blood illness during cold-water swimming
2. According to the passage, some doctors believe it is true that _______ .
A. Polar bears are bears swimming in freezing water    
B. cold-water swimming can make the body temperature dangerously high            
C. you are healthy if cold-water swimming turns your skin color blue           
D. cold-water swimming causes more heart attack in summer than in winter
3. The Polar Bears like to swim year-round, for _______ .
A. it is an easy way to keep the body warm in winter                        
B. they can stay young
C. they find it enjoyable and interesting
D. they might meet fewer troubles in life
4. Which of the following is TRUE according to the text ?
A.The Polar Bear is a club in which people swim to protect polar bears.
B. The club members are all over 60 years old.
C. There is no woman in the club.
D. None of the above.
5. This passage is mainly about _______ .
A. the requirements of the Polar Bear Club                
B. a group of cold-water-swimming lovers
C. the Polar Bears’ life in New York                 
D. doctors’ ideas about cold-water swimming

    You get all sorts of demands, and the mark of a good hotel is to supply whatever is asked for without sounding surprise. If a guest asks for rubber gloves. You don't ask why. You say, “No problem. What colour do you want？”
　　There have been some demands which, much as I would have liked to fill, I couldn't. A Japanese businessman， for example， thought the manager of a hotel was like the captain of a ship so he asked me to marry him and the woman he loved. There was one time, however, we did help out. A young man thought that if he asked his girlfriend to marry him at the Ritz she would say yes. He asked us to put the ring in a cake, and she accepted.
　　Top hotels are used more and more to impress. They are used for doing business. If you've got something to sell, take your clients(客戶) to the best hotel where the surroundings are quite helpful. A friend of mine working at Savoy Hotel tells story about a man who gave him 5 pounds to say “Good morning, Mr. Smith” when he walked through the door with two other men. This he did， and could hear Mr. Smith saying, “I do wish they would leave me alone at this place.”
　　According to Julian Payne， the most powerful people in any hotel are the porters， who carry bags for hotel guests. “Porters can do almost anything. They can get you tables at the best restaurants or tickets for a popular concert. Don't ask me how they do it or what their deal is because I don't know. Most of them have been there for years. They know more about the history of the hotel and the guests than anyone else. They are invaluable. A head porter will come in even on his day off so he can say hello to someone he remembers visiting the hotel years ago.”
56．When guests ask for something strange，the manager of a good hotel would think ______.
　　A．how he can meet their needs
　　B．why they have such demands
　　C．what problems the hotel has
　　D．who is the best person to go to

A．They sell tickets for concerts.
B．They know how to make a good deal.
C．They know a lot about the hotels and the guests.

  Driving while talking on a hand-held mobile phone has long been considered a danger. But even drivers who use hands free devices are a nuisance – because they are slowing everyone else down, according to a study.
David Strayer, a psychology professor in Utah University’s traffic lab, conducted a study involving 36 university students driving on motorways. Each used a hands free phone for half the trip but not for the other half. The students were told to obey posted speed limits and use turn signals but the rest of the driving decisions were up to them . What Strayer found is that when the drivers were distracted（使分心）by a phone conversation , they made fewer lane（車道） changes, drove slower and took longer to get where they were going. Fellow researcher Professor Peter Martin, who teaches civil and environmental engineering at Utat University, said,“Ordinarily a slower driver should be safer ， but that’s not the case when people are talking on a cell phone.”
In general , drivers who used mobile phones while driving took three percent longer to drive along the same high-density route than drivers who didn’t. When stuck behind a dawdling(磨蹭的) driver , it took them between 25 and 50 seconds longer to switch to an open lane to overtake. Those delays can add up when you consider studies that suggest as many as 10 percent of US drivers are using a cell phone at any one time. And delays in traffic streams of very small amounts can grow into massively when drivers are crossing a  highway.” Our next step is to use computer models to determine just how much those delays are costing drivers in time and in extra fuel costs,” Martrin said.
63. What does the underlined word in the first paragraph mean?
A. A person who is a volunteer.         B. A person who breaks the traffic law
C. A person who is annoyed by others.   D. A person who causes trouble
64. Which of the following is TRUE , according to Martin?
A. The more slowly a person drove, the safer he was.
B. Measures should be taken to stop using mobile phones.
C. Drivers using hand-held phones had less effect on traffic than those using hands free phones
D. Driving while using mobile phones could cost drivers time and money.
65. The passage is mainly about      .
A. traffic conditions in rush hours 
B. the use of mobile phones in the USA
C. using hands free devices behind the wheel
D. a comparison between hand-held phones and hands free ones

Critics of cloning often repeat the question related to the controversial(有爭(zhēng)議的) science “Just because we can, does it mean we should?”  The closer we come to being able to clone a human, the hotter the debate over it grows. For all the good things cloning may achieve, opponents say that it will do just as much harm. Another question is how to governing cloning process.
There is federal official law banning cloning in the United States, but several states have passed their own laws to ban the practice. The US Food and Drugs Administration(FDA), has also said that anyone in the United States attempting human cloning must first get its permission. In Japan, human cloning is a crime that is punished by up to 10 years in prison.
While laws are to ban cloning at this time, some scientists believe that the technology is not ready to be tested on humans. Ian Wilmut, one of the co-creators of Dolly, has even said that human cloning projects would be an irresponsible crime. Cloning technology is still in its early stages, and nearly 98% percent of cloning efforts end in failure. The embryos are either not suitable for implanting into the uterus(子宮) or they die shortly after birth.
The clones that do survive end up suffering from deadly or problematic genetic abnormalities(畸形). Some clones have been born with faulty heart, lung problems and blood vessel problems. One of the most famous cases was a cloned sheep that was born with but malformed arteries(畸形動(dòng)脈) leading to the lungs.
Opponents of cloning will point out that we can enthanize(安樂死) these faulty clones of other animals, but they ask what if a human clone is born with these same problems. Advocates of cloning respond that it is now easier to pick out faulty embryos even before they are implanted into the mother. The debate over human cloning is just beginning, but as science advances, it could be the biggest moral dilemma of the 21st century.
68. Which word in the text is the opposite of the underlined word “opponents”?
A. critics        B. advocates          C. scientists           D. co-creators
69. The writer writes this passage mainly to ________________.
A. support passing laws to ban human cloning
B. list problems with human cloning
C. introduce critics’ ideas about human cloning
D. state the debate over human cloning
70. Which of the following will Ian Wilmut probably NOT agree with?
A. Cloning technology is in its early stages.
B. Human cloning should be made illegal.
C. Very few cloning efforts are successful.
D. Cloning technology is ready to be tested on humans
