[EX Q]: Article: Australian scientists say an organic compound used by Indian women to paint dots or bindi on their foreheads could hold the key to a breakthrough in cancer treatment. Rose Bengal was first used in the early 1900s as a dye for food, textiles and cosmetics. But now it is proving to be a useful weapon in the fight against skin cancer. Television advertisements constantly warn of the dangers of overexposure to the fierce sun. Among them is the possibility of the disease melanoma , a type of skin cancer. More than 1,200 Australians die every year from the disease. Initial trials of a solution of Rose Bengal injected into some melanoma cells have had a 75 percent success rate in controlling the disease. Professor John Thompson, the director of the Melanoma Unit at the University of Sydney, says this organic dye could become a powerful cancer-fighting treatment. "We believe it works by getting into the tumor cells and causing them to self-destruct. But the exact mechanism by which it works is not totally clear. It's not useful for people who have a primary melanoma. The treatment of primary melanoma is surgical excision ,"he said. "It's useful to inject tumors for people who have recurrences; when the primary treatment has failed and when recurrence in the area, or at more distant sites has occurred." About 90 percent of Australians who develop melanoma survive thanks to early diagnosis and treatment. If left untreated, however, the disease can be fatal. Convincing younger people in Australia about the dangers of overexposure to the sun is a battle campaigners are constantly waging. Veronica Manock, a 21-year-old student, had two major operations to remove a cancerous tumor from her leg. "I've had a lot of friends who just said 'I thought it was just, you know, I'll get a mole cut out and that's it', whereas I don't think people realize how much danger they're putting themselves into and how easy it is to stop something like this happening to you just from doing little things,"said Marock. Other researchers in Australia are investigating genetic treatments to skin cancer. There is a pressing need for such research to produce effective treatments. Australians, the majority of whom are fair-skinned , are four times more likely to develop a melanoma than people in Canada, the United States or Great Britain.

[EX Q]: Article: Students in many countries are learning English. Some of these students are small children. Others are teen-agers. Many are adults. Some learn at school, others by themselves. A few learn English by learning the language over the radio, on TV, or in film. One must work hard to learn another language. Why do all these people want to learn English? It is difficult to answer this question. Many boys and girls learn English at school because it is one of their subjects required for study. They study their own language and maths and English: Some people learn it because it is useful for their work. Many people learn English for their work. Many people learn English for their higher studies, because at college or university some of their books are in English. Other people learn English because they want to read newspapers or magazines in English.
Question: People learn English _ .
Options: (A) at school (B) over the radio (C) on TV (D) not all in the same way
Asnwer: A
[EX A]: No

[EX Q]: Article: It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can't fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain. Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain. Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, and then he operated on them. He made the monkeys' blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys' brains. When the brain's temperature was 10degC, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.
Question: The biggest difficulty in operating on the damaged brain is that _ .
Options: (A) the time is too short for doctors (B) the patients are often too nervous (C) the damage is extremely hard to fix (D) the blood-cooling machine might break down
Asnwer: A
[EX A]:
Yes
