Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers.
Their study found that theobromine（可可堿）, 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 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 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 medicines are stopping coughs.
The team found that, when the volunteers were given theobromine, the capsaicin needed to produce a cough was around a third higher than in the placebo group. When they were given codeine they needed only slightly higher levers of capsaicin to cause a cough compared with the placebo.
The researchers said that theobromine worked by keeping down a nerve activity(神經(jīng)活動(dòng)), which cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness.
小題1: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
小題2:What was used in the experiment to cause coughing?
A．Theobromine. B．Codeine.C．Capsaicin.D．Placebo.
小題3: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
小題4: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

There was one thought that air pollution affected only the area immediately around large cities with factories and heavy traffic．At present, we realize that although these are the areas with the worst air pollution, the problem is really worldwide．On several occasions over the past decade，a heavy cloud of air pollution has covered the east of the United States and brought health warnings in distant areas away from any industrial cities．In fact，the very climate of the entire earth may be infected by air pollution．Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels(coal and oil)is creating a “greenhouse effect”—— keeping heat reflected from the earth and raising the world’s average temperature．If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York，Boston，Miami，and New Orleans will be in water．
Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth’s temperature—a result that would be equally disastrous．A drop of just a few degrees could create something close to a new ice age，and would make agriculture difficult or impossible in many of our top farming areas．Today we do not know for sure that either of these conditions will happen．Perhaps，if we are lucky enough，the two tendencies will offset each other and the world's temperature will stay about the same as it is now．Driven by economic profits, people ignore the damage on our environment caused by the “advanced civilization”．Maybe the air pollution is the price the human beings have to pay for their development．But is it really worth-while?
小題1:People used to think that air pollution_________ .
A．caused widespread damage in the countryside
B．a(chǎn)ffected the entire eastern half of the United States
C．had a very bad effect on health
D．existed merely in urban and industrial areas
小題2:As to the greenhouse effect, the author_________.
A．shares the same view with the scientists．
B．is uncertain of its occurrence
C．rejects it as being ungrounded
D．thinks that it will destroy the world soon
小題3:The underlined word “offset” in the second paragraph could be replaced by_______.
A．counter-actB．break fromC．get alongD．communicate
小題4:This passage is primarily about________ .
A．the greenhouse effect
B．the burning of fossil fuels
C．the potential effect of air pollution
D．the possibility of a new ice age

Since the 1970s, scientists have been searching for ways to link the brain with computers．Brain-computer interface（BCI） technology could help people with disabilities send commands to machines．
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated（展示）a small robotic wheelchair directed by a person’s thoughts．
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand．He could even talk as he watched the vehicle and guided it with his thoughts．
“Our brain has billions of nerve cells．These send signals through the spinal cord（脊髓）to the muscles to give us the ability to move．But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says．“Our system allows disabled people to communicate with external world and also to control devices．”
The researchers designed a special cap for the user．This head cover picks up the signals from the scalp（頭皮）and sends them to a computer．The computer interprets the signals and commands the motorized wheelchair． The wheelchair also has two cameras that identify objects in its path．They help the computer react to commands from the brain．
Prof．Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands．“The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices．One example is this wheelchair．”
He says his team has set two goals．One is testing with real patients, so as to prove that this is a technology they can benefit from．And the other is to guarantee that they can use the technology over long periods of time．
小題1:BCI is a technology that can         .
A．help to update computer systemsB．link the human brain with computers
C．help the disabled to recoverD．control a person's thoughts
小題2:How did Tavella operate the wheelchair in the laboratory?                                    
A．By controlling his muscles．B．By talking to the machine．
C．By moving his hand．D．By using his mind．
小題3:The team will test with real patients to         .
A．make profits from themB．prove the technology useful to them
C．make them live longerD．learn about their physical condition
小題4:Which of the following would be the best title for the text?
A．Switzerland, the BCI Research Center
B．New Findings About How the Human Brain Works
C．BCI Could Mean More Freedom for the Disabled
D．Robotic Vehicles Could Help to Cure Brain Injuries

I climbed Kilimanjaro with Lava Expeditions (探險(xiǎn)隊(duì)) during the rainy season.
I flew to Nairobi in Kenya and spent several days there. At my hotel in Nairobi I met the rest of the group with whom I would spend the next week. We all travelled on the bus together for a 6-hour journey into Tanzania and then Arusha , a quiet town.
After we arrived at our hotel in Arusha , we had dinner and a few drinks. Then we were introduced to more members including Taddeus Minja, the main guide, who was very experienced — climbing Kilimanjaro runs through the generations (代) of his family.
The next day the Lava Expeditions members checked if we had the correct and enough clothing for our expedition on Kilimanjaro. Only one person needed to bring more clothes.
After that we set off, walking in the rain through the beauty of the rainforest, all the way to the first camp. I was happy the next few days as the view was so wonderful and changed every day. I suffered a little during the trip and I felt so tired. But the members of Lava Expeditions provided me with lots of encouragement, which was one of the best memories. Finally we reached the top of Kilimanjaro in bright blue skies.

科目：高中英語(yǔ) 來(lái)源：不詳 題型：閱讀理解

In a world with limited land, water and other natural resources(資源), the harm from the traditional business model is on the rise. Actually, the past decade has seen more and more forests disappearing and the globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable(可持續(xù)的)ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the healthy while using its supply of natural resources.
Today, sustainable development is a popular trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decade. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy resolution. It is now trying hard to made full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil(棕櫚油), which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown more than 50%.
Governments can fully develop the potential of these new markets. First, they can set high  targets for reducing carbon emissions(排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge public expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from the traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of a growing population within the limits of this single planet. That is no small task, but it offers a large of new chances for sustainable product industries.
小題1:The traditional business model is harmful because of all the following EXCEPT that____.
A．it makes the world warmer
B．it consumes natural resources
C．it brings severe damage to future
D．it makes growth hard to continue
小題2:What can we infer from Paragraph2?
A．China lacks wind and solar energy
B．China is the leader of the low-carbon market
C．High-speed trains are a low-carbon development
D．Palm oil is made at the cost of valuable forests
小題3:To fully develop the low-carbon markets, governments can______.
A．cut public expensesB．forbid carbon emission
C．develop public resourcesD．encourage energy conservation
小題4:We can learn from the last paragraph that business have many chances to _______.
A．develop sustainable productsB．explore new natural resources
C．make full use of natural resourcesD．deal with the major challenge
小題5:What is the main purpose of the passage?
A．To introduce a new business modelB．To compare two business models
C．To predict a change of the global marketsD．To advocate sustainable development
