1 . Are you facing a situation that looks impossible to fix?

In 1969,the pollution was terrible along the Cuyahoga River Cleveland, Ohio. It    1    (be) unimaginable that it could ever be cleaned up. The river was so polluted that it    2    (actual) caught fire and burned. Now, years later, this river is one of    3    most outstanding（杰出的）examples of environmental cleanup.

But the river wasn’t changed in a few days    4    even a few months. It took years of work     5    (reduce) the industrial pollution and clean the water. Finally, that hard work paid off and now the water in the river is    6    (clean) than ever.

Maybe you are facing an impossible situation. Maybe you have a habit    7    is driving your family crazy. Possibly you drink too much or don’t know how to control your credit card use. When you face such an impossible situation, don’t you want a quick fix and something to change immediately?

While there are    8    (amaze) stories of instant transformation, for most of us the    9    (change) are gradual and require a lot of effort and work, like cleaning up a polluted river. Just be     10    (patience).

2 . Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)—either recorded or real—may even prevent elephants from damaging farmer’s crops.

In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.

Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a tree close to each family.

From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.

Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn’t tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.

5 . Cold weather can be hard on pets, just like it can be hard on people. Sometimes owners forget that their cats are just as used to the warm shelter (住所) as they are. Some owners will leave their animals outside for a long period of time, thinking that all animals are used to living outdoors. This can put their pets in danger of serious illness. There are things you can do to keep your animal warm and safe.
Keep your pets inside as much as you can when the weather is bad. If you have to take them out, stay outside with them. When you’re cold enough to go inside, they probably are too. If you must leave them outside for a long time, make sure they have a warm, solid shelter against the wind, thick bedding, and plenty of non-frozen water.
If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye on your pet’s water. Sometimes owners don’t realize that a water bowl has frozen and their pet can’t get anything to drink. Animals that don’t have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them.
1. What do we learn about pets from Paragraph 1?

A．They are often forgotten by their owners.	B．They are used to living outdoors.
C．They build their own shelters.	D．They like to stay in warm places.

2. Why are pet owners asked to stay with their pets when they are out in cold weather?

A．To know when to bring them inside.	B．To keep them from eating bad food.
C．To help them find shelters.	D．To keep them company.

3. If pets are left on their own outdoors in cold weather, they may          .

A．be short of clean water	B．dig deep holes for fun
C．dirty the snow nearby	D．get lost in the wild

4. What is the purpose of this text?

A．To solve a problem.	B．To give practical advice.
C．To tell an interesting story.	D．To present a research result.

6 . 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 problems，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 food

2. The underlined word “modest” in Paragraph 3 most probably means ________.

A．relatively high	B．extremely low
C．relatively low	D．extremely high

3. 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

7 . 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 researchers 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 increase,” 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 main idea of Paragraph 1?

A．Plants’ reaction to weather could have damaging effects on ecosystems.

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 change

3. 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 before

4. What can be inferred from the last two paragraphs about the world’s temperature?

A．It needs to be controlled within 2℃ in this century.

B．Its change will lead to weather extremes.

C．It is 0.8℃ higher in 1979 than that of 1900.

D．It has risen nearly 0.2℃ since 1979.

8 . If man’s best friend is a dog, then who is a dog’s best friend? That would be Rover, Glow, Ivan or Raina. They recently donated (捐赠) blood to other dogs. And they did it without having to travel far from home: they visited an animal bloodmobile.
Like the Red Cross vehicles for humans, the University of Pennsylvania’s traveling vet lab goes to where the donors are to make it easier to give. The bloodmobile makes weekly rounds through Philadelphia and New Jersey.
Like humans, not every dog is qualified(合格的) to donate blood. The dogs are examined for health first. Dogs must have the correct blood type, weigh at least 55 pounds and be under 8 year old. About 150 dogs take part in the program. Each donates three or four pints(品脱) a year, which can help animals suffering from illness like cancer or an accident like being hit by a car.
Sandy Lucas brought her 7-year-old dog, Raina, to the bloodmobile last week. She said she wouldn’t have taken the dog to Penn Vet’s animal hospital in downtown Philadelphia, which is twice as far from her home. “I was very, very excited that she had the right blood that was needed to help another dog out,” said Lucas. “We’ll surely do it again.”
Just like people, the donors get a snack and a heart-shaped sticker immediately after giving. What’s more, they receive dog food to take home.
If dogs are doing what they can to save other dogs, why can’t we do it to save other people? Next time you hesitate(犹豫) over whether to donate blood or not, think of the dogs.
1. The writer mentions Rover, Glow, Ivan and Raina in Para. 1 mainly because _________.

A．they are man’s best friends.

B．they are common names for dogs.

C．they get along well with other dogs.

D．they have donated blood to other dogs.

2. What do we know about the traveling vet lab?

A．It is a Red Cross vehicle.

B．It collects dogs’ blood for other dogs.

C．It travels through Philadelphia every day.

D．It was donated by the University of Pennsylvania.

3. What can we learn from Para.4?

A．Sandy Lucas is unwilling to let her dog donate blood.

B．The bloodmobile welcomes dogs from anywhere in the city.

C．Penn Vet’s animal hospital in downtown Philadelphia is popular.

D．The animal bloodmobile has made it easier for dogs to donate blood.

4. By writing the last paragraph, the author wants to ________.

A．ask us to help dogs.

B．show the importance of dogs.

C．encourage us to donate blood.

D．compare humans with dogs.

9 . A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover，these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns，potentially causing certain natural disasters all over the world.
In the past hundred years，humans have begun destroying rainforests in search of three major resources（资源）：land for crops，wood for paper and other products，land for raising farm animals. This action affects the environment as a whole. For example，a lot of carbon dioxide（二氧化碳）in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.There are two main reasons for this. Firstly，when people cut down trees，generally they can only use the land for a year or two. Secondly，cutting large sections of rainforests may provide a good supply of wood right now，but in the long run it actually reduces the world’s wood supply.
Rainforests are often called the world’s drug store. More than 25％ of the medicines we use today come from plants in rainforests. However，fewer than l％of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.
1. Rainforests can help to adjust the climate because they      

A．reflect more heat into the atmosphere

B．bring about high rainfall throughout the world

C．rarely cause the temperature to drop lower than l6℃

D．reduce the effect of heat from the sun on the earth

2. What does the word “this” underlined in the third paragraph refer to?

A．We will lose much more than we can gain.

B．Humans have begun destroying rainforests.

C．People have a strong desire for resources.

D．Much carbon dioxide comes from burning rainforests.

3. It can be inferred from the text that

A．we can get enough resources without rainforests

B．there is great medicine potential in rainforests

C．we will grow fewer kinds of crops in the gained land

D．the level of annual rainfall affects wind patterns

4. What might be the best title for the text?

A．How to Save Rainforests

B．How to Protect Nature

C．Rainforests and the Environment

D．Rainforests and Medical Development

10 . Last Friday a storm swept through two villages in the south China, destroying fourteen homes. Seven others were so badly damaged that their owners had to leave them, and fifteen others had broken windows or broken roofs. One people was killed, several were badly hurt and taken to hospital, and a number of other people received smaller hurt. Altogether over two hundred people were homeless after the storm.
A farmer, Mr. Tan, said that the storm began early in the morning and lasted for over an hour. “I was eating with my wife and children,” he said, “When we heard a loud noise. A few minutes later our house fell down on top of us. We tried our best to climb out but then I saw that one of my children was missing. I went back inside and found him, safe but very frightened.”
Mrs. Woo Mei Fong said that her husband had just left for work when she felt that her house was moving. She ran outside at once with her children. “There was no time to take anything,” she said, “A few minutes later, the roof came down.”
Soldiers helped to take people out of the flooded area and the welfare department (福利机构) brought them food, clothes and shelter.
1. How many homes altogether were damaged in the storm?

A．Fourteen	B．Twenty-one
C．Twenty-nine.	D．Thirty-six
