阅读理解。     Plants are flowering faster than scientists predicted (预测) in reaction to climate change, which could
have long damaging effects on food chains and ecosystems.
    Global warming is having a great effect on hundreds of plant and animal species around the world,
changing some living patterns, scientists say.
    Increased carbon dioxide(CO2)in the air from burning coal and oil can have an effect on how plants
produce oxygen, while higher temperatures and changeable rainfall patterns can change their patterns of
growth.
    "Predicting species" reaction to climate change is a major challenge in ecology," said the researches of
several U.S. universities. They said plants had been the key object of study because their reaction to
climate change could have an effect on food chains and ecosystem services.
    The study, published on the Nature website, uses the findings from plant life cycle studies and experiments across four continents and 1,634 species. It found that some experiments had underestimated (低估)
the speed of flowering by 8.5 times and leafing by 4 times.
    "Across all species, the experiments under-predicted the speed of the advance - for both leafing and
flowering - that results from temperature increases," the study said.
    The design of future experiments may need to be improved to better predict how plants will react to
climate change, it said.
    Plants are necessary for life on the Earth. They are the base of the food chain, using photosynthesis
(光合作用) to produce sugar from carbon dioxide and water. They let out oxygen which is needed by
nearly every organism on the planet.
    Scientists believe the world"s average temperature has risen by about 0.8? since 1900, and nearly 0.2?
every ten years since 1979.
    So far, efforts to cut emissions(排放)of planet-warming greenhouse gases are not seen as enough to
prevent the Earth heating up beyond 2? this century - a point scientists say will bring the danger of a
changeable climate in which weather extremes are common, leading to drought, floods, crop failures and
rising sea levels.1. What is the key information the author wants to give in Paragraph 1?A. Plants" reaction to weather could have damaging effects on ecosystem.
B. The increasing speed of flowering is beyond scientists" expectation.
C. Climate change leads to the change of food production patterns.
D. Food chains have been seriously damaged because of weather.2. We can learn from the study published on the Nature website that ______.A. plants" flowering is 8.5 times faster than leafing
B. there are 1,634 plant species on the four continents
C. scientists should improve the design of the experiments
D. the experiments failed to predict how plants react to climate change3. Scientists pay special attention to the study of plants because _______.A. they can prove the climate change clearly
B. they are very important in the food chains
C. they play a leading role in reducing global warming
D. they are growing and flowering much faster than before4. What can be inferred from the last two paragraphs about the world"s temperature?A. It has risen nearly 0.2? since 1979.
B. Its change will lead to weather extremes.
C. It is 0.8? higher in 1979 than that of 1990.
D. It needs to be controlled within 2? in this century.

     Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is
another factor that can cause your heart problems more immediately: the air you breathe.
     Previous studies have linked high exposure (暴露)to environmental pollution to an increased risk of heart problem,
but two analyses now show that poor air quality can lead to heart attack or stroke (中风)within as little as a few hours
after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物)were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate
study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of "moderate" (良好)quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14
hours of exposure.
     The authors of both studies stress that these risks are relatively small for healthy people and certainly modest
compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware
of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation
by the EPA of pollutants may not only improve environmental air quality but could also become necessary to
protect public health.


1. The text mainly discusses the relationship between          .A. heart problems and air quality
B. heart problems and exercising
C. heart problems and smoking
D. heart problems and fatty food2. The underlined word "modest" in Paragraph 3 most probably means         .A. relatively high
B. extremely low
C. relatively low
D. extremely high3. What can we learn from the text?A. Eating fatty food has immediate effects on your heart.
B. The EPA conducted many studies on air quality.
C. Moderate air quality is more harmful than smoking,
D. Stricter regulations on pollutants should be made.4. The author"s purpose of writing the text is most likely to       .

A. inform
B. persuade
C. describe
D. entertain

阅读理解。     On a grassy plain in South Africa, thousands of miles from home,two pairs of zoo-bred South China
tiger cubs-one-year-old Hope and Cathay and six-month-old Tiger Woods and Madonna are learning to
hunt in the wild. The hope is that they will one day pass on their skills to their young, allowing the next
generation to get back to wildlife reserves (保护区) in China.
       A survey shows that the tigers are in more danger of dying out than China"s most famous animal,the
giant panda. Forty years ago, about 4,000 South China tigers lived in the wild. Today there are only
about 30. An additional 64 live in 19 zoos in China,which are all descendants(后代) of six wild animals
seized in 1956.
     The cubs were born in zoos in China and removed from their mothers when they were three months
old. Their first home in South Africa was a one-acre camp where they stayed for a month. Their next
home was a ten-acre area,where they lived for three months to help them gradually get used to life
outside a cage.
     When the cubs first arrived in South Africa,they didn"t even want to leave their cages. It took weeks
to get them to eat chicken, used as they were to being fed beef at the zoo in China where they were born.
It took months of practice to hunt a live animal and then make the link between the kill and food. Now
just a few months on, and living in a 150-acre camp,they have become remarkably skilled hunters.
      All four animals will finally return to zoos in China while the pioneering pairs" cubs will grow up
completely wild. The aim is for the first rehabilitated tigers to go to reserves developed in China by 2008 ,when the Olympic Games will be held in Beijing.1. The tigers are sent to South Africa so that____.   A. their young can live in the wild
B. their young can have a better environment
C. they can get used to wildlife reserves
D. they can live a free life in the wild2. What does the fourth paragraph mainly talk about?   

A. The food the tigers ate.
B. The place where the tigers were trained.
C. The process(过程) to train the tigers.
D. The time it took to train the tigers.


3. The underlined part" the first rehabilitated tigers" refers to _____.   A. the tigers sent to South Africa
B. the pioneering pairs
C. the tigers" next generation
D. the zoo-bred tigers4. Which of the following is TRUE?   A. There are about 100 South China tigers at the zoos in China.
B. South China tigers at the zoos in China usually eat chicken.
C.In the hunting practice cubs didn"t eat what they hunted at first.
D. The four tigers will appear in the Olympic Games.

阅读理解。     I first met Richard Sandor around 10 years ago when discussions about creating a global carbon
market began. He"s been extremely important to the development of the emissions-trading (排污权交易
)industry since its beginnings. As chief economist for the Chicago Board of Trade in the 1970s, he had
helped develop the financial futures (期货) market, and in the late 1980s and early 1990s he all but
invented cap-and-trade programs for sulfur dioxide (SO?) emissions, the pollutant that causes acid rain.
The methodology was simple: the government puts a cap, or an upper limit on SO? emissions and then
the market takes over, with companies that can economically reduce SO? on their own allowed to sell
emissions fights to those that can"t. Doing the same thing with greenhouse emissions was the logical next
step, and from the 1992 Earth Summit on, Sandor was at the forefront of those efforts, launching the
Chicago and the European Climate Exchanges, where companies could meet to trade carbon.
     Sandor is a creator and a great promoter of new markets, and he has the vision, to create something
out of nothing. He doesn"t just work at the level of theory, but encourages others to get involved. And
he"s always been good at making money. He realized that if we built enthusiasm in a market for actually
valuing the reduction of carbon emissions-and the global carbon market is already worth more than
$30 billion-we"d remember for decades to come as a true pioneer-a man who used the power of
financial incentives (激励)as a force for change.1. The first paragraph is developed________.A. by space
B. in order of importance
C. by time
D. by comparison  2. According to Para. 1, who will buy emission rights?A. The government.
B. The market.
C. Companies that can reduce SO? emission.
D. Companies that can"t reduce SO? emission.3. We can learn from the passage that Richard Sandor _______.A. is trying to make the reduction of carbon emissions profitable
B. always works in a way that is not practical
C. is a man of imagination rather than action
D. is strongly against developing industry4. The author writes the passage in a tone of_______.A. praise
B. sympathy
C. doubt
D. regret
