[EX Q]: Article: The U.S. government may issue stronger regulations about the use of tobacco. Many governments and private buildings have "No Smoking" regulations. In airplanes, on trains and at cinemas, Golf courses are seriously thinking of keeping out smokers, so are schools, shopping malls and even football fields. So where do people go to fill their lungs with nicotine? The government is working on it. One suggestion is that the government set aside a piece of land somewhere in the United States where smokers could go when they want a cigarette. Yellow Stone Park has been in the list, but many people don't agree because they fear that second-hand smoking would make the bears there sick. The Mojave Desert in California is also being studied, and so are Las Vegas Casinos . The smokers were not too nervous about the government idea. They say they are not going to California just to light up. They have a right to smoke at home. To make life more pleasure for those who find it hard to give up smoking, the government is seriously thinking of getting somewhere for the smokers. The tobacco companies are fighting the idea like mad. They say nobody has proved that cigarettes are bad for you. They say as a matter of fact, the doctors have proved that a cigarette saved a person's life after that person was shot. Other places under consideration are: the cold areas in Alaska, the Rocky Mountain in Colorado and the Whitewater River in Arkansas.
Answer: are not so free
[EX A]: Smokers in the U.S. _ to light a cigarette now.

[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.
Answer: it can be effective in treating skin cancer
[EX A]: The information about Rose Bengal is wrong EXCEPT that _ .

[EX Q]: Article: There are many commonly held beliefs about eye glasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of vision if they have glasses inappropriate for their eyes. We have all heard some of the common myths about how eyesight gets bad. Most people believe that reading in dim light causes poor eyesight, but that is untrue. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bed, and watching too much television. However, although eyestrain may cause some pain or headaches, it does not permanently damage eyesight. Another myth about eyes is that they can be replaced, or transferred from one person to another. They are close to one million nerve fibers that connect the eyeball to the brain, so it is impossible to attach them all in a new person. Only certain parts of the eye can be replaced. But if we keep clearing up the myths and learning more about the eyes, some day a full transplant may be possible.
Answer: the structure of his eyes will keep the same as before
[EX A]:
If a child wears appropriate glasses, _ .
