The disease malaria(疟疾) has caused trouble to mankind throughout history. In the 1860s as the drug called chloroquine began to lose its effectiveness, malaria began to appear again in Southeast Asia. Every country in the world then poured huge amounts of human resources into discovering another anti-malaria drug In 1964, China put forward the plan to seek a breakthrough from among traditional Chinese medicinal drugs. There was no great discovery until 1981. When Chinese scientist Tu Youyou gave a speech titled" Chemical Research into Artemisinin(青蒿素)”. at an international conference of the WHO. The speech was regarded as a lifeline for malaria sufferers.
Tu Youyou graduated from the Medical College of Peking University. In 1969, just as the research into treating malaria had reached dead end, the 39 year-old Tu, in order to overcome this terrible problem, took on the job as head of a research team into this problem. The first thing Tu did was interview experienced doctors of Chinese medicine. Then she and her colleagues conducted various kinds of experiments on hundreds of kinds of Chinese medicinal herbs, including artemisinin. However, the results were disappointing: even those involving artemisinin, which had been universally well regarded, were less than satisfactory.
But later, when Tu found a relevant passage written by Ge Hong of the Eastern Jin Dynasty (317-420), it occurred to her that high temperatures destroy artemisinin's effectiveness: it needs a low temperature to work properly. The discovery pointed to a brand-new direction for Tu and her research team. Finally, in 1972, an extract(# R40) of it was found to be one hundred percent effective against the disease!
In 2000 the WHO announced artemisinin was a leading anti-malarial drug, and promoted it worldwide. So far, it has been playing a great role in the battle against malaria. Beginning at the age of 39, Tu devoted her fife-te-her reseach. In 2015, at the age of 85 and as the first Chinese scientist, she received a Nobel Prize in Physiology or Medicine. How did Tu manage to accomplish such a great achievement? You probably have the answer to that already.
1.What can be learnt about “chloroquine”from paragraph1?
A.It contributed to Tu’s great discovery.
B.It was discovered by experts in Southeast Asia.
C.It was a breakthrough out of Chinese medicine.
D.It used to be effective against the disease of malaria.

Malaria, the world’s most widespread parasitic (寄生虫引起的)disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can’t) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect. They can also attach themselves to blood vessels in the brain. If it doesn’t kill you, malaria can happen again and again for years. The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.

Just as mankind has always had a desire to fly, the human race has wanted to swim under the water since prehistoric times. Pictures of primitive devices to enable people to breathe underwater have been found dating from 3000 years ago, but our dream of moving freely beneath the ocean waves for long periods of time was only realized about 60 years ago, when French diving legend Jacques Cousteau developed the first practical Self Contained Underwater Breathing Apparatus(SCUBA). Since then the sport of SCUBA diving has gone from strength to strength.
Lovers of SCUBA diving like the feeling of weightlessness, the peace and quiet under the water, the ability to move in three dimensions and the sense of adventure they get while on a dive. SCUBA divers often travel to some of the most beautiful and remote places in the world in the search for rare underwater flora and fauna(动、植物). Palau, The Red Sea, The Maldives and Hawaii have many of the most popular diving sites, but recreational divers often have to make do with less exotic local destinations, like the North Sea in Britain.
SCUBA diving is not without its dangers, however. The mixture of nitrogen and oxygen divers breathe underwater, combined with the pressure under the water can be deadly if a diver rises too quickly to the surface, causing a condition called ‘the bends’. Divers can also get lost or trapped when diving on wrecks, and fatalities(死亡)are particularly common in cave diving, where divers add to the dangers of diving by swimming through underground caves filled with water. Diving can also be harmful to the underwater environment. However with proper precautions diving can open up a whole new world, far from the stresses of daily life.
63. What is the writer trying to do in the text?
A. Advertise some popular diving sites.
B. Describe how to dive underwater.
C. Warn people against diving in the sea.
D. Give information about SCUBA diving.
64. What can the reader learn from the text?
A. There is uncertainty about SCUBA diving safety.
B. Divers have caused a lot of damage to the environment.
C. SCUBA diving is an old sport with a long history.
D. Divers always face the pressures in their life.
65. How might the writer describe SCUBA diving?
A. Interesting. B. Relaxing. C. Frightening D. Unpleasant.
66. What do you think the author is most likely to suggest if he continues to write?
A. Getting out to dive underwater. B. Stopping damaging environment.
C. Making better use of SCUBA. D. Getting over the troubles of daily life.

Long-time exposure to air pollution can lead to physical changes in the brain and cause trouble in learning and memory, and even anxiety. This is suggested by the results of new research on mice.
While other studies have shown the harmful effects of polluted air in the lungs and heart, this is the first to show the negative effect on the brain.
The team of Laura Fonken, Randy Nelson, from the Ohio State University, USA, has spread to the brain a previous line of research which found that fine particulate (微粒) matter floating in the air mainly because of air pollution caused by humans, causes swelling in much of the body, and may be related to high blood pressure problems, and some other diseases.
In the research Fonken and his colleagues exposed mice to polluted air for six hours each day, five days a week, over a period of 10 months, almost half the average life length of mice.
Polluted air contains fine particles created by cars, factories and natural dust. Fine particles of this kind are tiny, about 2.5 micrometers in diameter, or about one-thirtieth the width of a human hair. These particles can go deep into lungs and other organs.
The concentration of this particulate material to which they exposed mice is equal to the concentration at which people can be exposed in some polluted urban areas.
After a period of 10 months, the researchers got the animals to have a series of behavioral tests. Both the behavior of mice and the results of neurological(神经的) tests done to them show that those within the polluted air had more problems in learning and memory, and higher levels of anxiety.
The results suggest that long-time exposure to polluted air can have measurable negative effects on the human brain and can cause a variety of mental health problems. This could have important consequences for those living and working in polluted urban areas.
1.The results of new research on mice first suggest that polluted air mainly does harm to ________.
A. normal organs B. lungs and heart
C. mental health D. blood pressure
2.The bad effects of tiny particles in polluted air are those except ________.
A. high blood pressure problems
B. making human hair thinner
C. different kinds of diseases
D. swelling in much of the body
3.From the last sentence we can infer that people living in polluted urban areas ________.
A. are likely to suffer from mental problems
B. can measure the negative effect on them
C. show little concern for air pollution
D. can be exposed to polluted air longer
4.Which of the following is the best title for the passage?
A. Long-time Exposure to Air Pollution
B. Evidence and Concern of Air Pollution
C. Measurable Effect on Human Brain
D. Mental Problems Caused by Air Pollution
