阅读理解。     A Low-Carbon Economy (LCE) or Low-Fossil-Fuel Economy (LFFE) is an economy
which has a smallest output of greenhouse gas (GHG) release into the atmosphere, but specifically
refers to the greenhouse gas CO2. Recently, most of scientific and public opinion has come to the
conclusion that there is such an accumulation of GHG (especially CO2) in the atmosphere due to
human-related activities that the climate is changing. The over-concentration of these gases is producing
global warming that affects long-term climate, with negative impacts on humanity in the foreseeable
future. Globally performed LCEs therefore, are proposed as a means to avoid catastrophic climate
change, and as a forerunner to the more advanced, zero-carbon society and renewable-energy economy.
    Some nations are low-carbon societies which are not heavily industrialized or populated. In order to
avoid climate change at any point in the future, all nations considered carbon-thick societies and societies
which are heavily populated, should become zero-carbon societies and economies. Several of these
countries have promised to become "low carbon" but not entirely zero carbon, and claim that release will
be cut by 100% by offsetting release rather than stopping all release. In other words, some release will
continue which will be offset, so they are not low-release.
     Nations seek to become low-carbon economies as part of a national global warming reduction
strategy. A comprehensive strategy to manage global warming is carbon neutrality , geoengineering
and adaptation to global warming .
     Nuclear power, or, the proposed strategies of carbon collection and storage (CCS) have been
proposed as the primary means to achieve a LCE while continuing to exploit non-renewable resources;
there is concern, however, with the matter of spent-nuclear-fuel storage, security and the uncertainty of
costs and time needed to successfully carry out CCS worldwide and with guarantees that the stored
release will notleak into the atmosphere. Alternatively, many have proposed  renewable energy should
be the main basis of a LCE, but, they have their associated problems of high-cost and inefficiency; this
is changing, however, since investment and production have been growing significantly in recent times.
Furthermore, regardless of the effect to the atmosphere by GHG releases, the growing issue of peak
oil may also be reason enough for a change to a LCE. 1. Low-carbon economy is encouraged for the following reasons except that ______. A. too much greenhouse gas CO2 is released
B. the over-concentration of greenhouse gases is producing global warming
C. it can avoid catastrophic climate change
D. low carbon and zero carbon nations and societies claim for it2. The underlined word in the first paragraph probably means ______. A. warning
B. pioneer
C. symbol
D. guide3. According to the passage, which of the following is NOT true?   A. Nuclear power could act as one of the primary means to achieve a LCE.
B. There"s worry about spent-nuclear-fuel storage, security and the uncertainty of costs.
C. The stored release will be likely to leak into the atmosphere.
D. Renewable energy tends to become the only means to achieve a LCE.4. From the last paragraph, we can infer that the writer"s attitude toward the proposal of adapting
renewable energy is ______.A. negative
B. positive
C. self-confident
D. doubtful

阅读理解     Each year there is an increasing number of cars as millions of new cars are produced in America.
Americans will not live without cars! However, some have realized the serious problem of air pollution
by cars. It is necessary to find ways to solve the problem of air pollution.
     One way to clean the air is to build a new kind of clean car. That’s what several of the large car
factories are trying to do. But to build a clean car is easier said than done. Progress in this field has been
slow.
     Another way is to take the place of the car engine by something else. Engineers are now working on
it. Many makers believe that it will take years to develop a practical model for us.
     To prevent the world being polluted by cars, Americans have to make some changes in the way of
their life. They have to cut down on the number of their cars and are encouraged to travel and go to work by bike. But this change does not come easily. Many workers may find themselves without jobs if a car
factory closes down. And the problem of their pollution would become less important than that of
unemployment.
     Americans may live a happy but sad life for a long time because of the car problem.

A growing number of health, hunger, and sustainable (可持续的) agriculture groups today announced plans for Food Day-a nationwide campaign to change the way Americans eat and think about food. Food Day will encourage people around the country to sponsor or participate in activities that encourage Americans to "eat real" and support healthy, affordable food grown in a sustainable, humane way. Organizers hope Food Day will inspire Americans to hold thousands of events in schools, college campuses, houses of worship and even in private homes aimed at fixing America"s food system. A Food Day event could be as small as a parent organizing a vegetable identification contest at a kindergarten class-or as massive as a rally (集会) in a city park, with entertainment and healthy food. Health departments, city councils and other policy makers could use Food Day to launch campaigns, hold hearings, or otherwise address communities food problems. The campaign will advocate progress toward five central goals: Reducing diet-related disease by promoting healthy foods. The American diet is too low in fruits, vegetables, and whole grains and too high in fatty meat, soft drinks and salty packaged and restaurant foods-contributing to hundreds of thousands of premature deaths each year. Supporting sustainable farms and stopping subsidies to agribusiness. Billions of federal dollars a year would be better spent helping environmentally conscious family farmers than hugeagri business operations. Expanding access to food and alleviating hunger. Far too many Americans don"t know where their next meal is coming from, or have access to fresh produce in their neighborhood. Reforming factory farms to protect animals and the environment. Farming of animals can and should be done without cruelty, and without degrading the quality of life. Curbing junk-food marketing to kids. Food companies should not be targeting children with foods that promote tooth decay, obesity and other health problems.
1.What is the best title of the text?
A. Food Day Campaign B. Eat Real and Keep fit C. How to Observe Food Day D. Food Problems in the USA
2.What can we learn from Paragraph 2?
A. Food problems are not easy to deal with. B. Food Day events should be held in public places. C. Kindergarten kids are unable to identify vegetables. D. People are invited to create their own Food Day events.
3.One of the aims of Food Day is to ____.
A. target children with junk food B. operate more agribusiness C. increase access to food D. cancel a series of events
4.The underlined word "curbing" in the last paragraph is closest in meaning to " ".
A. controlling B. enlarging C. evaluating D. providing
5.We can infer from the text that _____.
A. Food Day will not help preserve natural resources. B. Food Day can be an opportunity to solve food problems. C. Food Day has so far achieved all the central goals. D. there are different ideas and views about Food Day.

〔1〕Secondhand smoke is a byproduct of cigarette, cigar or pipe smoking. Secondhand smoke occurs when tobacco burns or when smokers exhale, and it is inhaled involuntarily by non-smokers. 〔2〕Secondhand smoke___________________.The first is called side stream smoke, which is the smoke released from the burning end of a cigarette or cigar, or from tobacco burning in the bowl of a pipe. The second is called mainstream smoke, which is exhaled by a smoker. 〔3〕When nonsmokers are exposed to secondhand smoke, they inhale many of the same cancer-causing chemicals that smokers inhale. According to the U.S. Surgeon General, cigarette smoke contains more than 4,000 chemical compounds, including more than 50 cancer-causing chemicals, and at least 250 chemicals that are either toxic or carcinogenic. 〔4〕Both side stream and mainstream smoke are dangerous to nonsmokers. Side stream smoke is generated at lower temperatures and under different conditions than mainstream smoke. As a result, it contains higher concentrations of many of the toxins found in cigarette smoke. 〔5〕Secondhand smoke has been designated as a known human carcinogen by the U.S. Environmental Protection Agency, the National Toxicology Program, and the International Agency for Research on Cancer. Secondhand smoke also is listed as an occupational carcinogen by the National Institute for Occupational Safety and Health. 〔6〕According to the 2006 report by the U.S. Surgeon General, there is no risk-free level of exposure to secondhand smoke: even small amounts of secondhand smoke exposure can be harmful to people"s health. Separating smokers from nonsmokers, cleaning the air, and ventilating buildings can help. However, they cannot eliminate the exposure of nonsmokers to secondhand smoke.
1.What is the main idea of the text? (no more than 10 words) _______________________________________________________________________ 2.Which sentence in the text is closest in meaning to the following one?

The rising costs of health care have become a problem for many countries in the world. To deal with this problem, it is recommended that a big part of the government"s health budget be used for health education and disease prevention instead of treatment. Actually, many kinds of diseases are preventable in many ways and preventing a disease is usually much cheaper than treating it. For example, people could avoid catching a cold if they dressed warmly when the weather starts getting cold. But many people get sick because they fail to do so, and have to spend money seeing a doctor. Daily habits like eating more healthy food would have kept millions of families from becoming bankrupt if the patients had taken measures for early prevention. For instance, keeping a balanced diet, such as not consuming too much animal fat and insuring a steady intake of vegetables and fruits, seems to be quite important. One very effective and costless way of prevention is regular exercise, which is necessary for a healthy mind and body. Regular exercise, such as running, walking, and playing sports is a good way to make people feel better or reduce stress. In addition, health education plays a key role in improving people"s health. By giving people more information about health, countries could help people understand the importance of disease prevention and ways to achieve it. For example, knowing one"s family medical history is an effective way to help keep healthy. Information about health problems among close relatives will make them aware of what they should do to prevent certain diseases through lifestyle changes, which will work before it is too late. However, stressing disease prevention does not mean medical treatment is unimportant. After all, prevention and treatment are just two different means toward the same effect. In conclusion, we could save money on health care and treat patients more successfully if our country spends more money on health prevention and education.
1. What"s the best title of the passage?
A. Prevention or Education? B. Prevention or Treatment? C. Health or Illness? D. Exercise or Illness?
2. Which of the following can replace the underlined word "bankrupt"?
A. Unable to be cured B. Unable to pay one"s debts C. Stronger than ever before D. More successful than ever before
3. We learn from the passage that ______.
A. dressing warmly can prevent diseases B. a balanced diet is cheaper than regular exercise C. the more health education, the better D. the government"s health budget should be increased

The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colour in meats and other food additives (添加剂) caused cancer. Yet, these additives remain in our food, and it is difficult to know which things on the wrappings (包装) of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar tings are supplied to animals not for their health, but just to make a profit. The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.
1. Which food is the healthiest at present?
A. chocolate B. alcohol C. fresh vegetables D. French fries
2. According to this passage, we can know .
A. perhaps most of human illness is caused by what we eat B. perhaps most kinds of cancer are related to what people eat C. cancer was discovered in 1945 D. science has made food unfit to eat
3. Things that are used to keep colours in meats are .
A. harmful B. useless C. helpless D. dangerous
4. All the additives __ .
A. are bright and colourless B. are not bright and colourful C. have indirect effects on our health D. have direct effects on our health
5. Which of the following is not true?
A. Some wrappings of food are harmful. B. Farmers try to make more money on the market by fattening their animals. C. "The practice continues" means "things are still going on like that". D. We needn"t take care of what we eat.
