An important scientific report announced ¡°irrefutable£¨²»ÄÜ·´²µµÄ£© proof¡± that climate change is happening and it¡¯s all our fault. How long has it been before people are against the global warming idea? But here¡¯s a funny thing. Last year there was a very bad hurricane season in the Caribbean when, among other disasters, New Orleans was all but wiped off the map. We were wisely informed by the experts at the time that this was owing to global warming.
I remember watching a BBC science programme and hearing a learned professor with a beard tell us, ¡°The increased frequency and strength of hurricanes is what we shall have to learn to expect given global warming.¡±
This year there have been far fewer hurricanes and those there have been were relatively mild. Why£¿Global warming again of course. Professor Bjorn Lomborg, author of The Skeptical Environmentalist, writes, ¡°In the constant media reports of possible greenhouse related disasters, almost any event is now linked to climate change.¡± He adds, ¡°We should not spend vast amounts of money to cut a tiny slice of the global temperature increase when this leads to a poor use of resources and when we could probably use these funds far more effectively in the developing world.¡± For saying this, Lomborg has had death threats.
Other scientists who do not toe the global warming-is-happening-and-it¡¯s-all-our-fault line have received the same. There are plenty of people who count against global warming. A world of senior climatologists and meteorologists wrote to the Times last year to complain that they couldn¡¯t get their research findings published ¡ª because they disagreed to it. We have had a warm autumn. The experts,  fanatics£¨¿ñÈÈÕߣ© all of them, put it down to global warming. If we have an extra cold winter, they will tell us it¡¯s a result of global warming. If my big toe feels cold or hurts badly, it will be owing to global warming.
52. The purpose of this passage may be to ____.
A. support the idea of global warming  
B. organize a debate about global warming
C. speak out against the global warming idea
D. encourage people to use money effectively
53. What happened to New Orleans last year?
A. It was badly destroyed.                          B. It disappeared in the world.
C. It witnessed global warming.               D. It experienced several disasters.
54. From the passage, we can infer that ____.
A. people are taking too many efforts to stop global warming
B. people have realized the side effect of development
C. a different idea sometimes may cost one his life
D. the majority usually stand for the correct opinion
55. The main idea of the last paragraph may be ____.
A. global warming may lead to toe¡¯s catching cold in a sense
B. the Times refuses to publish articles on global warming
C. a warming autumn is not related to global warming at all
D. it is certainly incorrect to owe everything to global warming

   For the people living in the Nile Basin, the river is their life:. This 6,825 km waterway, whose watershed£¨Á÷Óò£© covers three million square kilometers, flows through mountains ,woodlands, lakes and deserts. Its potential for fishing, tourism and shipping is great¡ªbut so are its challenges.
Water shortage , already serious in Egypt and Sudan , will soon influence several other countries in the watershed as well. Today, about 160 million people depend on the Nile River for their living. Within the next 25 yeas ,the district's population is expected to double, adding to the demand brought about by growth in industry and agriculture. The frequent drought£¨¸Éºµ£©adds to the urgency.
Water quality is also a problem. Precious soil is washed out to sea. Wastes from industry and agriculture create pollution. Higher concentrations of salt influence irrigated soils. Water-borne diseases continue unchecked. In areas where it's hot and damp, water hyacinths choke off lakes, dams and other sections of the river, making it difficult for fishing and other businesses to move forward.
Native people along the narrow area of farmland have watched the sand move closer day by day. They¡¯ve seen the river change course, and their only source£¨À´Ô´£© of water thickened with mud. They¡¯re very poor and have few choices.
But a new program, the Nile Basin Initiative £¨NBI£©£¬is offering very practical assistance. The program is more than just a water-management project. It¡¯s a plan for the social and economic development of a vast district: it concentrates on the needs of the poorest of the poor and the environment that supports them.
These are whole ecosystem problems, calling for united solutions£¨½â¾ö°ì·¨£©. Half the Nile Basin's countries are among the world's poorest nations£»yet, somehow, they must find the  resources, skills and political will to overcome these challenges.
68. What are the great challenges the Nile Basin faces£¿
A. The development of .shipping industry.
B. Overfishing of native people.
C. Water shortage and water quality.
D. Increasing population and tourism.
69. The underlined word ¡°hyacinths¡±£¨in Paragraph 3£© refer to ¡°          ¡±.
A. animals                           B. plants                     C. rocks                                D. salts
70. The program NBI is mainly aimed at           .
A. preventing water pollution                             B. changing the river course
C. improving living condition of the poor
D. preventing land from becoming desert
71. What would be the best title of this passage£¿

We each have a memory. That¡¯s why we can still remember things after a long time. Some people have very good memories and they can easily learn many things by heart, but some people can only remember things when they say or do them again and again. Many of the great men of the world have got surprising memories.
A good memory is a great help in learning a language. Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages as easily as one because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the pupils have so little time for it, and they are busy with other subjects, too.
But your memory will become better and better when you do more and more exercises.

Sometimes we cry because we are sad and sometimes because we are extremely happy£®An irritant(´Ì¼¤Îï)£¬such as onion(Ñó´Ð) smell or grains of sand in the eye£¬can also make cry£®In this case tears perform an obvious role in getting rid of substances that might harm the surface of the eye£®
Dr£®William Frey of the Dry Eye and Tear Research Center at St£®Paul in Minnesota£¬USA£¬believes that tears from emotional causes may perform a similar role£®He thinks that crying could get rid of emotional stress by washing away a chemical in the blood caused by strong emotions. To prove his theory, he hopes first to identify this chemical and then see if it is found in tears of sadness or happiness£®  
So far, Dr£®Frey has failed to find out the difference between emotional tears and tears caused by an irritant in the eye£®This may be because these substances themselves cause a degree of stress and emotion£®What he has identified in all tears is a variety of biochemicals(Éú»¯Îï)which are one of the causes of stress£®A more detailed study may help us understand why sufferers from stress-related disorders cry less often than healthy people£®Dr£®Frey is also very interested to see if there are any physiological(ÉúÀíѧµÄ)explanations for why women£¬in general£¬cry five times more often than men£¬on average£®
64. The main purpose of Dr£®Frey¡¯s study of tears is to           
A. show that there are two types of tears£¬caused by irritants and by emotions

The earth is getting warmer. The planet is suffering. But what can you do about it? Reduce the amount of waste you generate. Use cleaner energy sources and go greener today, starting with these steps:
1. Get a reusable water bottle
Americans buy about 25 billion single-serving plastic water bottles each year. That's an average of 83 bottles per person per year. Plastic bottles take plenty of resources to produce, including fuel for transportation and petroleum to make the plastic. Even recycling bottles uses energy.
2. Eat less meat
You don't need to become a vegetarian to help save the planet. Eating meat just one day less a week can reduce your negative impact on the environment. More water, energy and land are required to produce meat than to produce grain.
3. Switch to energy-efficient light bulbs
Most households use standard incandescent (°×³ãµÄ) bulbs. But compact fluorescent (Ó«¹âµÄ) light bulbs, or CFLs, use 66 percent less energy than standard bulbs, produce just as much light, last up to 10 times longer and don't need to be replaced as often. If every household in the United States replaced just one incandescent light bulb with a CFL bulb, it would equal removing one million cars from the road.
4. Buy organic and local food
Did you know that only 1 percent of pesticides (ɱ³æ¼Á) applied to crops reach the pests they target? The rest enter the environment. Organic food is grown without the use of pesticides. Organic farming can use 50 percent less energy than traditional farming methods. Buying local food saves on the fuel used to transport food grown elsewhere, thousands of miles across the country or around the world.
5. Recycle your electronics
Everyone knows the importance of recycling glass and plastic, but what about cell phones, computers, CDs and batteries? Electronics are responsible for about 40 percent of toxic (Óж¾µÄ) heavy metals such as lead and mercury. Check with your city's recycling facilities to see if they take electronics.
72. The readers of this passage are called on to ______.
A. help reduce global warming               B. use water in a wise way               C. donate money for charity                      D. keep a balanced diet
73. What is an advantage of CFLs according to the passage?
A. They use more energy but produce more light.                                   B. They can last longer so don't need to be replaced often.                                        C. They cost less than standard incandescent bulbs.                                         D. They are as energy-efficient as incandescent bulbs.
74. Which of the following figures is correct according to the passage?
A. Every year an American buys 63 plastic water bottles on average.                   B. Eating meat one day less a week helps cut environment costs.                                   C. 99 of the pesticides used on crops is effective in practice.                                         D. Electronics account for half of poisonous heavy metals on the earth.
75. Which can be the best title for this passage?
A. Why is the earth getting warmer?           B. What can we do about pollution?              C. How can you lead a greener life?          D. Who is to blame for global warming?

Astronauts¡¯ meals have come a long way from the free-dried powders and semi-liquid pastes of decades ago, now US scientists want to grow vegetables in mini-greenhouses on the moon.
Scientists say they are looking forward to a time when residents of future lunar or even Martian outsteps will be able to dine on fresh vegetables. Paragon Space Development Corporation has unveiled what it called the first step toward growing flowers¡ªand eventually food-oh the moon.
This is a sealed greenhouse that looks like a bell jar encased in a 46-cm triangular aluminum frame. It is designed to safely land a laboratory plant on the lunar surface, and protect it while it grows.
The miniature greenhouse is to be launched into space by Odyssey Moon Ltd, a participant in the Google Lunar X Prize. This competition offers $20 million to any entrant who can launch, hand and operate a rover on the lunar surface.
Paragon officials say future testing of the ¡°Lunar Oasis¡± will be driven by Odyssey¡¯s flight schedule, which will not happen until 2012 at the earliest.
When it does lift off the greenhouse will contain the seeds of Brassica, a hardy plant related to Brussels sprouts and cabbage. Because Brassica goes from seed to flower in just 14 days, it can complete its life cycle in single lunar night.
¡°Coloizing the Moon or Mars seems so far away, but it is important that we do this research now, ¡± Paragon president Jane Poynter said.
¡°It takes a long time to get a lot of research, and to get integrated, reliable efficient systems before colonists move in,¡± she said.

A£®predict the astronauts¡¯ meals in the future
B£®introduce an experiment ¡°Lunar Oasis¡±
C£®tell us the future development of astronomy
D£®focus on the human¡¯s great progress

B£®Paragon and NASA will carry out the test separately
C£®Lunar Oasis is a series of experiments carried out in space
D£®the earliest testing of the Lunar Oasis may be in 2012

The journey two divers made some time ago to the deepest point on the earth makes us realize how much of the world still remains to be studied. The two men went down seven miles to the bottom of the Pacific Ocean inside a small steel ball to find out if there are any ocean currents(Ë®Á÷) or signs of life.
It was necessary to set out early, so that the ball would come to the surface in daylight, and be easily found by the mother ship which would be waiting for it. The divers began preparations early in the morning and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.
The divers felt as if they were going down steps as they passed through warm and cold layers (²ã) of water. In time the temperature dropped to the freezing point. They kept in touch with the mother ship by telephone telling how they felt. Then, at a depth of 3,000 feet, the telephone stopped working and they were quite cut off from the outside world. All went well until some four hours later at 30,000 feet, the men were frightened by a loud, cracking noise. Even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer windows that had broken. Soon afterwards, the ball touched the soft ocean floor raising a big cloud of "dust" made up of small dead sea creatures. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite untroubled by the great water pressure. But they did not dare to leave the lights on for long, as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the faint but clear voices of the divers were heard on the mother ship seven miles away. After a stay of thirty minutes the men began their journey up, arriving three hours later, cold and wet through, but none was worse for their experience.
65. The purpose of the divers' journey to the deepest point on the earth was to find
A. if there are water currents, and life in the great depths
B. if people can stand the severe cold in the great depths
C. if there are steps in the great depths
D. if the telephone works well in the great depths
66. The divers set out early in the morning so that                .
A. they could return to the surface during the day
B. they could see at the bottom of the ocean
C. they could avoid the cold at night
D. they could stay long at the bottom
67. As the divers went down to the ocean floor, the telephone              .
A. kept working all the time
B. stopped working at a depth of 3,000 feet and began working again after they reached the bottom
C. stopped working at a depth of 3,000 feet and began working again at 30,000 feet
D. stopped working at a depth of 3,000 feet and began working again when they returned to the same depth
68. On the ocean floor, the divers found that               .
A. there was no life but some small dead sea creatures
B. fish were swimming as freely as they do near the surface
C. fish were not swimming freely in the dark water
D. fish were not swimming freely under the high water pressure
