Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers.
Their study found that theobromine, found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present.
The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. “While coughing is not necessarily harmful(有害的) it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem,” said Professor Peter Barnes.
Ten healthy volunteers(志愿者) were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicine are stopping coughs.
The team found that, when the volunteers were given theobromine, the capsaicin need to produce a cough was around a third higher than in the placebo group. When they were given codeine they need only slightly higher levers of capsaicin to cause a cough compared with the placebo.
The researchers said that theobromine worked by keeping down a verve activity(神经活动), which cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness.
According to Professor Barnes, theobromine ______.

A．cannot be as effective as codeine

B．can be harmful to people’s health

C．cannot be separated from chocolate

D．can be a more effective cure for coughs

What was used in the experiment to cause coughing?

A．Theobromine.

B．Codeine.

C．Capsaicin.

D．Placebo.

We learn from the text that volunteers in the experiment _____.

A．were patients with bad coughs

B．were divided into the three groups

C．received standard treatments

D．suffered little side effects

Which of the following would be the best title for the text?

A．Codeine: A New Medicine	B．Chocolate May Cure Coughs
C．Cough Treatment: A Hard Case	D．Theobromine Can Cause Coughs

Electricity shortage leaves Afghanistan in the dark. Electricity is in short supply in the Middle Eastern Nation of Afghanistan. Only 6 percent of the country’s residents have electric power, according to the Asian Development Bank, an organization that works to reduce poverty.
Some residents in Kabul received only 3 hours of electricity a day last fall. Others received none. Kabul is the capital of Afghanistan. “It’s dark everywhere,” says city resident Gul Hussein. “Some of our neighbours are using candles.”
Experts say water shortage is partly to blame. Water is used to make electricity. In Kabul, power becomes scarce in midsummer, when the region’s hydroelectric(水力发电的) dams dry up. Hydroelectricity is made by the force of falling water.
Kabul’s growing population is also a cause. Since the late 1990s, the city’s population has jumped from less than 1 million to more than 4 million people. Now even more electricity is needed.
Despite receiving millions of dollars in international aid, the country’s electricity shortages continue. Still, Afghans hope for a solution. One plan is to import, or bring in, power from the nearby country Uzbekistan. Afghan officials also spoke with U.S. president about the nation’s need to make its own electricity.
“ Life takes power,” says Jan Agha, a worker from Kabul. “If you have electricity, life is good; but if there’s no electricity, you go around like a blind man.”
1.One reason for electricity shortage is _________
A. the lack of international aid
B. the shortage of hydroelectric dams
C. the increase of population
D. the low temperature in midsummer
2. Which of the following will probably a solution for the problem of electricity shortage?
A. To build more hydroelectric dams.
B. To advise people to use less electricity.
C. To buy electricity from America.
D. To produce electricity on its own.
3. What does the underlined word “scarce” mean in paragraph 3?
A. not normal    B. not little    C. not effective   D. not enough
4. Which one should be the best title for the passage?
A. Water Shortage in Afghanistan       B. Population Lead to Lack of Electricity
C. Electricity Shortage in Afghanistan   D. Help Needed in Afghanistan

Remembering names is an important social skill．Here are some ways to master it．
Recite and repeat in conversation．
When you hear a person’s name，repeat it．Immediately say it to yourself several times without moving your lips．You could also repeat the name in a way that does not sound forced or artificial．
Ask the other person to recite and repeat．
You can let other people help you remember their names．After you’ve been introduced to someone，ask that person to spell the name and pronounce it correctly for you．Most people will be pleased by the effort you’re making to learn their names．
Admit you don’t know．
Admitting that you can’t remember someone’s name can actually make people relaxed．Most of them will feel sympathy if you say．“I’m working to remember names better．Yours is right on the tip of my tongue．What is it again?”

The year 2009 is the Year of Ox. The ox is a representative of the farming culture of China. In the farming economy, oxen are the major animals pulling plows (犁).
Of course, the good of oxen is not limited to plowing. In fact, they are seen as "boats on land" for their ability to carry loads. Besides, the whole body of an ox is full of treasures. Their meat and milk are food full of nutrition, and their skin can be used to make clothes and shoes. With all these qualities, oxen are regarded as generous creatures(动物) .
In the past, oxen played an important role in the spiritual life of the Chinese. Even today, oxen still play a special part in some folk activities. For example, some people who 1ive in southwest China will cook cattle bone soup and share it among family members when holding the ceremony for children who reach 13. They believe that the cattle bone soup represents the blood relationship among family members. In order to express their love for oxen, people in some other areas will run to shake off diseases on the 16th day of the first month by the lunar calendar (农历), and during their run they will take their oxen along, which indicates they regard the creature as human.

第三部分：阅读理解（共20小题；每小题2分，满分40分）
Put yourself in these tourists’ position. You are walking an icy mountain path in the Alps in Europe. Suddenly you spot a body on the ground, face downward and stuck to the ice. You think someone may have been murdered or in a fatal accident. So you rush back and call the police. The police, however, quickly realize that this body is different from others they’ve found on the mountain. For one thing, it is mostly undamaged. For another, its skin is dried out, like a mummy’s（木乃伊）. And there is an old small stone knife beside the body.
The body turned out be much older than the tourists could have guessed. When specialists（专家）had a chance to examine it, they discovered it had been there for about five thousand years!
How could a body stay preserved for all this time? Two things probably helped. First, the place where the man died was somewhat sheltered, so animals couldn’t get at it. Then he was quickly covered by falling snow. Wind blowing through the snow probably “freeze-dried” his body, removing all moisture(水分) from it.
Objects found with the body told something about the Iceman’s life. He wore a well-made fur jacket and trousers. He clearly had been hunting, because he carried arrows, and animal bones were nearby. He also had a grass cushion for sitting or sleeping on. Perhaps he was tired when he lay down for the last time.
The body was found in 1991, when some of the ice on the mountain melted. Searching for the cause of the Iceman’s death, scientists put the body back into cold conditions---and hoped.
1. What does the underlined word “spot” in the first paragraph probably mean?
A. lay       B. dig          C. find         D. carry
2. Which of the following is NOT the reason that the police realize that the body is different from others?
A. The body’s skin is like a mummy’s.    B. Beside the body is an old small stone knife.
C. The body is much older than others.   D. The body is mostly undamaged.
3. At what time of a year was the Iceman probably died?
A. Early fall.   B. Late spring.    C. Summer.    D. Winter.
4. This passage is mainly to _____________
A. tell us what life was like 5, 000 years ago.
B. warn us not to go to the Alps.
C. introduce a mysterious Iceman to us.
D. explain the mystery of the Alps.

Jamie Oliver has been invited by Gordon Brown to prepare a banquet at No. 10 for President Barack Obama and other leaders of the G20, offering a cut-price menu to reflect times when trade and industry are far from prosperous and the rate of employment is decreasing.
Downing Street sources say Oliver, the well-known chef, will cook using “honest high-street products” and avoid expensive or “fancy” ingredients.
The prime minister is trying to avoid a repeat of the embarrassment last year when he sat down to an 18-course banquet at a Japanese summit to discuss world food shortages.
Obama, President Nicolas Sarkozy of France, Chancellor Angela Merkel of Germany and other leaders will be served by apprentices (学徒) from Fifteen, the London restaurant Oliver founded to help train young people in poverty in order to make a living by mastering a skill.
Brown wants the dinner to reflect the emphasis of the London summit, which he hopes will lead to an agreement to lift the world out of recession. “To be invited to cook for such an important group of people, who are trying to solve some of the world’s major problems, is really a privilege,” said Oliver.
“I’m hoping the menu I’m working on will show British food and produce is some of the best in the world, but also show we have pioneered a high-quality apprentice scheme at Fifteen London that is giving young people a skill to be proud of.”
The chef has not yet finalized the menu, but is expected to draw inspiration from his latest book, Jamie’s Ministry of Food, which has budget recipes for beef and ale stew (啤酒炖菜) and “impressive” chocolate fudge cake.
1. The underlined word “recession” in Paragraph 5 is closest in meaning to “____________”.
A. business B. opposition C. discussion D. depression

3. The menu of the banquet for the leaders of the G20 is supposed to _________.
A. include all delicious British food
B. use inexpensive produce with special characteristics
C. be rich, varied and of high quality
D. imitate the menu of last Japanese summit
4. Which of the following is TRUE according to the text?
A. Oliver is honored to be invited to cook for the G20 leaders.
B. Altogether three presidents are mentioned in the text.
C. President Barack Obama offers the cut-price menu.
