     For well over a thousand years,smallpox was a disease that everyone feared.The disease killed much of the native population in South America when the Spanish arrived there in the early sixteenth century.By the end of the eighteenth century,smallpox was responsible for about one in
ten deaths around the world.Those who survived the disease were left with ugly scars on their sjun.
It had long been well known among farmers that people who worked with cows seldom caught smallpox;instead,they often caught a similar but much milder disease called cowpox (牛痘) .A Bridsh doctor called Jenner was extremely interested in this,and so he studied cowpox He believed that,by vaccinating (给接种疫苗) people with the disease,he could protect them against the much worse disease smallpox.In 1796,he vaccinated a boy with cowpox and,two months later,with smallpox.The boy did not get smallpox.In the next two years,Jenner vaccinated several children in the same way,and none of them got the disease.
News of the success of Jenner’s work soon spread.Vaccination soon became a common method to protect people against other diseases caused by virus,such as rable (狂犬病),and vaccines (疫苗) were sent across the world to the United States and India.
It took nearly two centuries to achieve Jenner’s dream of getting free of smallpox from the whole world.In 1967,the world Health Organization (WHO) started a great vaccination program,and the last known case of smallpox was recorded in Somalia in 1977.The story of vaccinations does not end there,however.There are many other diseases that kill more and more people every year.Besides,many new diseases are being discovered.The challenge for medical researchers will,therefore,probably continue for several more centuries

Geniuses amaze us,impress us and make us all a little jealous. How do they differ from the average person?Scientists are working hard to figure out that answer. Tune in to the National Geographic Channel to find out about the discoveries they’re making in the series My Brilliant Brain.
When Marc Yu was only two years old,he began to play the piano. After a year, he started learning pieces by Beethoven. Now he’s a world-famous concert pianist at age eight. He learns newer and more difficult pieces with ease and can identify any note he hears. He seems to be specially designed for music. In Born Genius, National Geographic looks at the science behind child prodigies (神童) to explain why some children seem to be born without limits.
Geniuses didnt come naturally to Tommy McHugh. His came only after he nearly died from bleeding in his brain. After recovering, McHugh’s head was filled with new thoughts and picture. So, he began to express them in the form of poetry and art. Now, he’s a seemingly unstoppable creative machine. Suffers of brain injury have shown that great mental ability can sometimes come from damage or disease. Accidental Genius explores this puzzling relationship.
Can normal people be trained to be geniuses? Susan Polger has shown no sign of extraordinary intelligence. Yet, during her childhood, she studied thousands of chess patterns and learned to recognize them immediately. As a result, she was able to beat skilled adult players by age 10 and can now play up to five games at the same time without even seeing the boards. Make Me a Genius examines what is takes to turn an ordinary brain into that of a genius.
If becoming a genius were easy, we’d all be done. Yet, there is much more to super intelligence than simply being born lucky. Learn more about amazing brains this month on National Geographic’s My Brilliant Brain.

As a boy, Charles Robert Darwin collected anything that caught his interest: insects, coins and interesting stones. He was not very clever, but Darwin was good at doing the things that interested him.
His father was a doctor, so Darwin was sent to Edinburgh to study medicine, and was planned to follow a medical career. But Charles found the lectures boring. Then his father sent him to Cambridge University to study to be a priest. While at Cambridge, Darwin’s interest in zoology and geography grew. Later he got a letter from Robert Fitzroy who was planning to make a voyage around the world on a ship, the Beagle. He wanted a naturalist to join the ship, and Darwin was recommended(推荐). That voyage was the start of Darwin’s great life.
As the Beagle sailed around the world, Darwin began to wonder how life had developed on earth. He began to observe everything. After he was home, he set to work, getting his collection in order. His first great work The Zoology of the Beagle was well received, but he was slow to make public his ideas on the origin of life.
Later Darwin and Wallace, another naturalist who had the same opinions as Darwin, produced a paper together. Darwin’s great book, On the Origin of Species by Means of Natural Selection (《物种起源》) appeared. It attracted a storm. People thought that Darwin was saying they were descended from monkeys. What a shameful idea! Although most scientists agreed that Darwin was right, the Church was still so strong that Darwin never received any honors for his work.
Afterwards, he published another great work, The Descent of Man. His health grew worse, but he still worked. “When I have to give up observation, I shall die,” he said. He was still working on 17, April, 1882. He was dead two days later.
Which of the following would be the best title for the passage?

A.Charles Darwin’s ideas
B.Charles Darwin’s works
C.Father of modern biology: Charles Darwin
D.The greatest scientist: Charles Darwin

In the United States, 30 percent of the adult (成年人) population has a “weight problem”. To many people, the case is clear: we eat too much. But scientific evidence(证据)does little to support the idea. Going back to the America of 1910, we find that people were thinner than today. Yet they ate more food. In those days, people worked harder physically, walked more, used machines much less, and didn’t watch TV.
Several modern studies, moreover, have shown that fat people do not eat more on average (平均) than thinner people. In fact, some investigations (调查), such as a 1990 study of 3,545 London office workers, show that fatter people eat less than slimmer people.
Studies show that slim people are more active than fat people. A study by a research group of Stanford University School of Medicine found the following interesting facts:
The more the men ran, the more fat they lost.
The more they ran, the more they ate.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
What kind of physical problem do many adult Americans have?

A.They are too thin. B.They work too hard.
C.They are too fat. D.They lose too much fat.

Which of the following words can take the place of the word “slim” in this passage?

A.poor B.thin C.healthy D.rich

Your body, which has close relations with the food you eat, is the most important thing you own, so it needs proper treatment and proper nourishment (营养).The old saying “An apple a day keeps the doctor away” is not as silly as some people think. The body needs fruit and vegetables because they contain vitamin C. Many people take extra vitamins in pill form, believing that these will make them healthy.
But a good diet is made up of nourishing food and this gives all the vitamins you need. The body doesn’t need or use extra vitamins, so why waste money on them?
In the modern western world, many people are too busy to bother about eating properly. They throw anything into their stomachs, eating hurriedly and carelessly. The list of illnesses caused or made worse by bad eating habits is frightening,
