题型：吉林省同步题难度：来源：
Dutch men in which deaths from heart disease were more than 50 percent lower among those who
consumed at least an ounce (盎司)of salt water fish per day compared to those who never ate fish.
The Dutch research is one of three human studies that give strong scientific support to the long
held belief that eating fish can provide health benefits, particularly to the heart.
Heart disease is the number-one killer i
n the United States, with more than 550,000 deaths occurring from heart attacks each year. But previous research has shown the level of heart disease
is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths,
for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and
among the Japanese, whose daily fish consumption(消费量) averages more than 3 ounces.
For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish.
At the start of the study, average fish consumption was about two-thirds of an ounce each day, with
more eating lean fish than fatty fish.
During the next two decades, 78 of the men died from heart disease. The fewest deaths were
among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos.
This relationship was true regardless of other factors such as age, high blood pressure, or blood
cholesterol(胆固醇) levels.
B. People who regularly eat fish never suffer from heart disease.
C. Heart disease causes more deaths in America than any other disease.
D. There is a low level of heart disease in such countries as Japan and Greenland.
B. fresh fish
C. fish that live in salt water
D. fish that have little fat
B. the effect of fish eating on people"s health
C. the changes in people"s diet
D. the daily fish consumption of people in different cultures
B. in America
C. in the countries with high consumption of fish
D. in the countries with good production of fish

| 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 w  e are doing is making sure we get the most carbon dioxidefriendly planets.We promise that100% 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.Wehave 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.
