     Climate scientists hit back at disbelievers yesterday with a new study which brought about the evidence
for man-made global war ming was"stronger than ever".
     After analyzing more than 100 scientific papers published in the last few years, a team of British
researchers say there is an"in creasingly small possibility" that the world is warming up because of natural
variations (變動) in climate.
     Instead, man-made global warming-caused by the burning of fossil fuels-is making its mark on every
continent and ocean, they say.
     The studies used computer models to see whether changes in air temperature, sea ice, sea temperature,
wetness, rainfall and ocean saltiness recorded in the last 50 years could be explained by nature.
     Since 1980,the average global temperature has increased by around0.5℃,they found. The same warming
pattern was also found deep in the world's oceans.
     Natural forces such as volcanic eruptions and returning chan ges in the brightness of the sun could not
explain what was happen- ing to the world's climate, Dr Stott said.
     The sun's output had actually fallen over the last 50 years, he said.
     Even if the sun had got warmer over the last few decades-as some skeptics say-both the upper and lower
layers of the atmos phere should have got hotter.
     However, in the last 50 years the lower atmosphere has warmed while the upper atmosphere has actually
cooled, Dr Stott said.
     Drier parts of the world are getting drier, while wetter areas are getting more rain-a finding in agreement
with man-made climate change, the report found.
     And the amount of mid summer sea ice in the Arctic is also declining over time-even with the natural
yearly variations, the study found.
     The study comes along with growing public doubt about climate change.
1. With enough evidence the climate scientists prove _____.
A. global warming is disappearing recently
B. mankind isn't to blame for global warming
C. mankind is to blame for global warming
D. global warming will disappear sooner or later
2. What caused the global warming according to the British researchers?
A. Frequent volcanic eruptions across the world.
B. The increase of the brightness of the sun.
C. The warming pattern of the world's oceans.
D. The burning of fossil fuels by the human being.
3. The underlined word "skeptics" in Paragraph 8 refers these people who_____.
A. believe that mankind is to blame for global warming
B. believe global warming will disappear sooner or later
C. doubt the global warming will disappear sooner or later
D. doubt the global warming is caused by humankind
4. What can we infer from the last sentence of the passage?
A. The study has made the public live in a terrible dream at present.
B. Many people don't believe the study of the British researchers now.
C. The public have been used to the climate changes these years.
D. The result of the study comes from the opinions of the public.

     Do you have a sore (痛的) throat, a running nose and a headache? Do you keep coughing and
sneezing? If you do, the chances are that you have a cold or perhaps flu-but which one? Although both
colds and flu are caused by viruses (病毒), they are very different illnesses.
     Colds, which usually last about a week, affect the nose most. They commonly cause a runny nose and
sneezing. Sometimes, they cause a headache, a cough and slightly aching muscles.
     Flu is much more serious illness and is caused by different group of viruses. People with flu usually get
all the symptoms (癥狀) described above. However, they also get a high fever, a dry cough and much
worse aching. Fever is one of the typical (典型的) symptoms of the flu for all ages. The symptoms also
last much longer. Sometimes they don't disappear for at least two weeks.
     Flu can be a deadly disease. The elderly, who are weaker and less healthy than most younger people,
can die from flu. This is one reason why old people are advised to have a flu injection (預(yù)防針) before
the start of winter when flu is most common. This injection is inexpensive and definitely worth it.
     If you have a cold or flu, you must always deal with used tissues carefully. Don't leave dirty tissues on
your desk or on the floor. Someone else has to pick these up and viruses could be passed on. And finally, remember to cover your nose and mouth when you sneeze!You don't want to see the small drop of
liquids blown out of your nose and mouth when you sneeze, do you? Disgusting (討厭的), eh? Now you
can undersdand why it's a good idea to cover your nose and mouth when you sneeze!

     For Americans, a mosquito bite is an itchy (發(fā)癢的) bother. But for many in Africa, a tiny bite can be
deadly. One million people die each year of malaria, a disease spread by infected mosquitoes. Most of these
people live in Africa, and are under age 5.
     Malaria can be prevented and treated. However, many African nations don't have the funds (基金) to
fight it. Nothing but Nets (NBN) hopes to change that. The United Nations Foundation created the campaign
in 2006. The aim is to prevent malaria by covering sleeping areas with nets. Hanging bed nets treated with
insecticide (殺蟲劑) is the simplest way to stop mosquitoes from biting at night. The chemicals last four to
five years. For $10, anyone can send a net to Africa and help save a life.
     So far, NBN has raised $19 million and delivered 700 000 nets to seven countries. Families are taught how
to use the nets. Kids also get vaccines (疫苗) and vitamins. "Women line up for miles to get the medicine for
their kids," says NBN director Elizabeth McKee Gore. "They understand the importance." So do kids in this
country. "They get so excited thinking of ways to raise money," says NBN spokesperson and basketball star
Ruth Riley.
     NBN's biggest fund-raiser is Katherine Commale, a seven-year-old girl. She's been spreading the information
about bed nets for the past two years. To show how they work, she and her brother made a video. "We teach
that bed nets can save lives," she said.
     Katherine has raised $ 42 000 for NBN. "She just wants those who need a net to have one," says her morn,
Lynda. "It's pretty simple to her." To find out how you can help, visit nothingbutnets, net.
1. Why don't those African nations do something about malaria?
A. Because the disease cannot be prevented and treated.
B. Because those nations don't know what to do with it.
C. Because those nations don't have the money for it.
D. Because nothing but nets can change it.
2. The underlined word "they" here refers to "_____".
A. bed nets
B. fund-raisers
C. families who are taught to use the nets
D. Katherine and her brother
3. How does Katherine Commale raise money?
A. By visiting nothingbutnets, net.
B. By spreading information about bed nets.
C. By teaching people how to use bed nets.
D. By making video programs.

閱讀下列材料，從所給的六個選項(A、B、C、D、E和F)中，選出符合各小段的最佳的標(biāo)題選項。
選項中有一項是多余選項。
A. Illegal hunting has caused a decrease in the number of sea turtles.
B. Most turtles are eaten by Mexicans and Mexican Americans.
C. A campaign to protect sea turtles.
D. Many sea turtles are killed for people's eating turtles in a religious observance.
E. Government should prevent sea turtle hunting to increase the number of the species.
F. A letter was written to Pope to save endangered sea turtles.
1._____   
    Environmental groups in the United States are leading a campaign to save thousands of
endangered sea turtles. They have asked Pope John Paul the Second to ban turtle meat during
the Christian religious observance known as Lent. Christians observe Lent in preparation
for the holiday of Easter.
2._____
    Environmental groups say illegal turtle hunting is one of the major threats to
endangered sea turtles in southern California and Mexico. It has been illegal to harvest
and eat sea turtle meat in Mexico for more than ten years. However, demand for sea turtle
meat is widespread in both Southern California and Mexico. Biologists believe that illegal
hunting is one of the main reasons for the sharp drop in sea turtle population during the
past thirty years.
3._____
    The week before Easter Sunday is an especially deadly time for the turtles. As many
as 5000 turtles are killed during this time each year. Many Mexicans and Mexican
Americans eat turtle meat during the days before Easter. Many people do not eat meat during
this holy time in order to obey the rules of Lent. Because sea turtles swim, many people
consider them to be fish. Fish is permitted during Lent.
4._____
    The Sea Turtle Conversation Network is a union of fishermen, environmental activists
and researchers. They sent a letter to Pope John Paul, urging the Roman Catholic Church
leader to officially declare that sea turtle flesh is meat, not fish or seafood. They say
thousands of these endangered animals would be saved if people did not eat them during
this religious period. The letter also asked members of the Catholic Church to obey laws
banning the capture of turtles in Mexico and the United States.
5._____
    About 35,000 endangered sea turtles are killed illegally near the coasts of Baja,
California each year. Studies have shown a sharp drop in the numbers of females. They
travel from as far away as Japan to lay their eggs on local beaches. Environmental
activists say hunting sea turtles for their meat is the main barrier to the recovery of
the species. They have urged the governments of the United States and Mexico to improve
enforcement of the ban on sea turtle harvesting.

     Some years ago industries had more freedom than they have now, and they did not need to be as careful
as they must today. They did not need to worry a lot about the safety of the new products that they developed.
They did not have to pay much attention to the health and safety of the people who worked for them. Often
new products were dangerous for the people who used them; often conditions in the work place had very bad
effects on the health of the workers.
     Of course sometimes there were real disasters which attracted the attention of governments and which
showed the need for changes. Also scientists who were doing research into the health of workers sometimes
produced information that governments could not ignore. At such times, there were inquiries into the causes
of the disasters or the problems. New safety rules were often introduced as a result of these inquiries; however,
the new rules came too late to protect the people who died or who became seriously ill.
     Today many governments have special departments that protect customers and workers. In the U.S., for
example, there is a department that tests new airplanes and gives warnings about possible problems. It also
makes the rules that aircraft producers must follow. Another department controls the foods and drugs that
companies sell. A third department looks at the places where people work, and then reports any companies that
are breaking the laws which protect the health and safety of workers. Of course, new government departments
and new laws cannot prevent every accident or illness, but they are having some good results. Our work places
are safer and cleaner than before. The planes and cars that we use for travel are better. Producers are thinking
more about the safety and health of the people who buy and use their products.
1. It can be inferred from the passage that in the past ____.
A. workers often got ill because of the poor working conditions
B. companies were free to put out any products they wanted to
C. many people were killed by dangerous products
D. industries were as careful in management as they are today
2. As can be seen in the passage ____.
A. governments and companies had different opinions about the safety of products
B. scientists also helped improve the safety and health of workers and customers
C. government officials often did not listen to scientists
D. governments paid no attention to the safety of products at all 
3. From the passage, we know that some years ago safety rules ____.
A. were put forward due to scientists' recommendations
B. came into being as a result of the workers' demands
C. were introduced because quite a number of people were killed or seriously injured
D. were effective enough to protect workers and customers
4. The special departments protect customers and workers in many ways EXCEPT by ____.
A. testing new products
B. designing new products
C. controlling the sale of products
D. inspecting work places

     China's giant panda shows the achievement of the international effort to save animals that are now in danger. In television programmes we often see pandas playing funny games. Children have panda toys and beautiful
cards with pictures of lovely pandas in them. They often visit the giant pandas in the zoo on their holiday and
have a good time there.
     However, scientists are worried about the future of giant pandas. They know only about 1,000 giant pandas
remain alive today. They think the giant panda will die out in 30 years if the present conditions are not improved.
      It is reported that the giant pandas have a very low birthrate. About 115 pandas live in zoos and research
centers mainly in China, but during the past ten years they produced only 34 young pandas that are still alive.
Survival rate for giant pandas in the wild are probably the same or lower. There are several reasons for the low
birthrate. The main reason is that male pandas can make love with females in a very short season, only a few
days a year. When they do have babies, females often produce two pandas, but the mother is usually not able to care for both of them. The new-born pandas weigh only a few grams each. They are too weak to live without
special care. In the zoo, scientists can help the mothers care for the young pandas, but those living in the wild
do not get enough help. It is very difficult for mother pandas to bring up their young pandas.
     Conditions for the giant pandas have been worse in recent years. Pandas in China continue to reduce in
number. We know pandas live on bamboos. But sometimes all the bamboos in one area die. The pandas there
have nothing to eat and die of hunger.
     Giant pandas now live in thirteen separate protected areas in China. Several years ago the Chinese
government and the International Wild Life Organization agreed on a project of protecting giant pandas in the
wild. We hope it could be helpful.
1. What does the writer think of the giant pandas?
A. They are funny.
B. They are dirty.
C. They are lovely.
D. They are naughty.
2. According to this passage we know most of the giant pandas live _____.
A. in the wild all over the world
B. in the zoos and research centers
C. in the area where there are plenty of bamboos for them to eat
D. in thirteen separate protected areas in our country
3. Scientists are worried about the future of the giant pandas because _____.
A. sometimes all of the bamboos die in the area where the giant pandas live and they have nothing to eat
B. giant pandas that still live in the wild can not get enough help from humans
C. only a small number of giant pandas remain alive today and their birth rate is too low
D. male and female giant pandas often refuse to make love in the right season
4. The low survival rate of young giant pandas has much to do with the fact that ______.
A. mother pandas are usually unable to take care of both young pandas born
B. female pandas are able to have baby pandas only in a special time
B. young pandas weigh only a few grams each and they are too weak
D. male and female pandas often refuse to have babies in the right time
5. If the present conditions are not improved, giant pandas in the world will disappear _____.
A. in less than a few years
B. in thirteen years
C. in thirty years
D. in the twenties

     There's no doubt that fast food has become an important part of modern life, especially among teenagers.
According to research, in the UK 80% of meals are eaten outside the home. And more than 50% of teenagers
eat, on average, more than one hamburger every three days. The percentage is high and nutritionists (營養(yǎng)專
家) are worried, but is fast food really as harmful as they say it is?
     Here is what two experts, Jake Hyde and Ursula Birkbeck, have to say on the subject. " Fast food is junk
food," says Jake Hyde.
     "Fast food is of very little nutritional value. It is full of fat, especially the harmful type, which is found in
meat, butter, cheese and mayonnaise. We need to cut down on fat if we want to stay healthy. Another thing
is that fast food contains too much salt and sugar and too many additives (添加劑 ). It is also low in vitamins
and fiber, because it includes hardly any vegetables. As a result, it doesn't provide us with enough nutrients,
just lots of calories. Most teenagers who have made fast food an important part of their diet are overweight.
This, along with the fact that they hardly ever take any exercise, puts their health at risk. It can lead to serious
health problems like heart disease or diabetes."
     "People shouldn't feel guilty every time they have a burger," says Ursula Birkbeck." What is in it not that
bad. Don't forget that red meat is a good source of iron and cheeseburgers (干酪漢堡包 ), for instance,
contain calcium. Chips, which most people think are unhealthy, are not so bad after all, because potatoes are
rich in Vitamin C. However, we shouldn't eat too much sauce or mayonnaise. Nowadays, fast food restaurants
pay attention to health matters and nutrition. They have improved the quality of their food, use fewer additives,
vegetable oil for cooking and some even use low-fat products. Also, most places offer salad bars, which give
people the chance to balance fast food with vegetables that contain other nutrients. So, people don't need to
prevent fast food from their diet completely. It's all a matter of what type of fast food they choose to eat, how
often and what else they eat during the day."
1. From the first paragraph we know that _____.
A. it's doubtful that fast food has become an important part of modern life
B. most meals in the UK are eaten inside the home
C. over half of the British teenagers average over one hamburger every three days
D. nutritionists are sure that fast food is very harmful
2. The underlined word "mayonnaise" in Paragraph 3 is a type of ______.
A. fat
B. food
C. meat
D. additive
3. The difference of the two experts' opinions lies in ______ .
A. whether fast food has little nutritional value
B. whether fast food is full of fat
C. whether fast food has improved its quality
D. whether fast food restaurants pay attention to health matters
4. What would be the best title for the passage?
A. Fast food-junk food
B. Fast food-friend or enemy?
C. Which expert is right?
D. The fast food restaurants are improving

     A new weapon is on the way in the fight against smoking in Europe. Soon when smokers buy cigarettes,
they might see a shocking photo of a blackened lung or a cancer patient staring back at them from the packet.
     Some boys may think of smoking as cool and sexy. Their friends won't agree when they see their packets
of cigarettes lying on the table. The European Union announced on October 22, that it had chosen 42 photos
that showed the damage cigarettes could do to the body. It called on member nations to put these pictures on
packets to discourage young smokers. To catch the attention of teenagers, the special packets warn of
long-term medical dangers, like cancer. Short-term effects, like bad skin, are also on the list.
     "The true fact of smoking is disease, death and horror. That is the message we should send to the young,"
said David Byrne, an EU health official. "Hopefully these pictures will shock students out of their love for
cigarettes."
     The EU head office hoped the pictures would work better than current written warnings on packs of
cigarettes. The warning included "smoking kills" and "smoking can lead to a slow and painful death."
     So far, Ireland and Belgium have shown interest in the photos. Canada has used similar pictures and
warnings on cigarette packs since 2000. The country has recently seen a fall in the number of smokers.
According to studies, smoking is the single biggest cause of avoidable death in EU. Every year more than
650,000 smokers die, more than one person a minute.
1. What would be the best title for the text?
A. New Ways to Stop Smoking.
