Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.     The total amount of packaging has increased by 12% between 1999 and 2005. It now makes up a third of a typical household"s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.     Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for burying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.       But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it is also applied to a wide range of consumer products, which often have far more packaging than necessary.      There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary materials are collected. We need to face the wastefulness of our consumer culture, but we have a mountain to climb. 1. What does the underlined phrase "that over-consumption" refer to? A. Using too much packaging.           B. Recycling too many wastes.  C. Making more products than necessary.   D. Having more material than is needed. 2. The author uses figures in Paragraph 2 to show ___________.  A. the tendency of cutting household waste     B. the increase of packaging recycling C. the rapid growth of supermarkets             D. the fact of packaging overuse 3. According to the text, recycling ___________.  A. helps control the greenhouse effect         B. means burning packaging for energy C. is the solution to gas shortage               D. leads to a waste of land 4. What can be inferred from Paragraph 4? A. Unpackaged products are of bad quality.   B. Supermarkets care more about packaging.  C. It is improper to judge quality by packaging.  D. Other products are better packaged than food. 5. What can we learn from the last paragraph? A. Fighting wastefulness is difficult.       B. Needless material is mostly recycled.  C. People like collecting recyclable wastes.  D. The author is proud of their consumer culture.

I suppose that having been brought up in the countryside and close  to animals,it wasn"t remarkable (不平常的)when I decided  to become a vet(兽医). Luckily I was also good at all the necessary science subjects. So after the college entrance examination I found myself at a veterinary college,training to look after animals in all kinds of situations. I hoped that I would be able to work in the research field so that I could find cures for animal diseases.       Much to my surprise,I found public health care was a very important aspect of my course. This is an area of animal medicine where a vet"s work has many things in common with the work of a doctor of human diseases. I particularly liked it because I recognized that the study of animal diseases can help human medicine. As we know,many infectious diseases come from animals-including SARS and bird flu. Some of the infections have only been understood after carefully analytical work in labs by animal doctors. They helped identify the animal source for diseases such as SARS. They were also the first to identify various kinds of viruses. Sometimes vets are also able to suggest a cure for human illnesses. When I found this out I was determined to make public health medicine my chosen career.       After graduation,I applied for a job in public health. Soon I found myself concerned with the problem of bird flu. This is  an illness that attacks birds,but humans can catch the disease  if they are in close contact with infected birds. Though the job  is dangerous,it makes me proud that vets and other animal   disease researchers are in the front line helping to fight these  unknown human diseases. 1. The writer wanted to become a vet mainly because______. A. he did well in all necessary subjects B. he wanted to help animals C. he was close to animals in his early life D. he wanted to find cures for human diseases 2. What made the writer particularly like the course of public health care was that________. A. it was both important and interesting B. it could help him connect many human diseases with animals C. it made a vet"s work very much like a doctor"s D. it could help human medicine by studying animal diseases 3. What can be followed if this passage continues? A. The writer"s happy family life. B. How the writer did research work in studying bird flu. C. How the writer dealt with the relationship with other workmates. D. What difficulty the writer met in the research work. 4. Which of the following is implied in the passage? A. Animals with infectious diseases should be killed. B. Keeping animals is dangerous to humans. C. Dangerous as a vet"s job is,it is significant to the human race. D. Animal researchers work in the same way as human doctors. 5. Which of the following statements is NOT true? A. Being a vet is helpful to both animals and humans. B. Vets can cure both animals and humans. C. Vets helped identify animal resources for SARS. D. Both SARS and bird flu are infectious diseases coming from animals.

Sir Richard Branson today offered a $25,000,000 prize for scientists who find a way to save the planet from the effects of climate change.     Supported by the former US vicepresident Al Gore and other environmentalists, the boss of Virgin Atlantic airlines called for scientists to come up with a way to take greenhouse gases out of the atmosphere.      "What we are doing is making sure we get the most carbon dioxidefriendly planets.We promise that 100% of profits we make from our transportation business are put into things like the prize we"ve offered today.We shall convince people that we are facing a threat which is urgent and there"s no superhero.We have no hope of a meaningful solution unless we find a way to work together."he said.     Mr Gore said global warming was manmade and was like the planet suffering from a"fever". He said, "Humans had slipped into a way of thinking that was centered on"short term satisfaction", and now meet the challenge of "transforming ourselves and changing the structures of everything we do"".      Reacting to the launch of the prize, Tony Jupiter, the Friends of the Earth"s director, warned against wasting time waiting for new inventions.He said, "Sir Richard"s initiative (初衷) may encourage inventors to develop a wonder technology to deal with carbon dioxide of the atmosphere.But many of the ways, such as energy efficiency and renewables, already exist, and it is essential that these be put into practice as soon as possible.Moreover, Sir Richard must also look at his business activities and the contribution they make to climate change.The world will find it very difficult to settle climate change if air travel continues to expand and space tourism is developed." 1.

What would you think if I told you I could eat 40 percent more food than other people-eating boxes of ice cream, bowls of noodles and plates of meat-all while losing weight?      You might hate me, thinking I have one of those annoyingly good metabolisms(新陈代谢)that just burn up fat the instant it enters my body.You might wonder if I have an intestinal(肠的)worm, or perhaps an eating disorder.Or maybe you"d just shrug your shoulders and figure I have a rich fantasy life.      You"d be wrong.      For my body to finish such a surprising task, I would have to be a mouse.Not just any mouse, but one lucky enough to be involved in a new study at Baylor College of Medicine in Houston.      After identifying an enzyme(酶)that allows fat to be stored in the body, scientists fed mice without those enzymes, and found those mice were able to consume far more food than other mice-and still weigh 10 to 15 percent less.      Best of all, the mice that had no enzymes were in very good health, producing baby mice with no problem and generally acting like any other mouse.That"s great news for obesity researchers, who think that scientists may figure out a way to prevent the fat?metabolizing(脂肪代谢)enzyme in humans and control weight gain.And such a pill would be very exciting for many people who are struggling to get rid of dangerous extra pounds.      But don"t start planning any big dinner just yet. At this point, of course, any pill for humans is but a twinkle(闪烁) in the eye of every medicine company"s CEO.More tests are to be made, and eventually humans will be introduced in the test.      But for now,unfortunately,control in diet is still the key. 1. What does "such a surprising task" in Paragraph 4 refer to? A. Eating a lot of food while losing weight. B. Burning up fat very quickly. C. Controlling the diet. D. Having a rich fantasy life. 2. Why did the author say he/she had to be a mouse in Paragraph 4? A. Because a mouse can lose weight no matter how much it eats. B. Because the weight losing tests were made on the mouse. C. Because the mouse has a very good metabolism. D. Because the author wants to try the food without the enzyme. 3. In the experiment, the mice without those enzymes_______. A. were in good condition   B. put on weight C. became weak   D. could not have baby mice 4. What does the author want to show through the last two paragraphs? A. You can be free of guilt when having big dinners. B. Scientists cannot find the key to identifying theenzyme. C. Don"t overeat before the test is made on humans. D. It is unnecessary to control weight at present.
