Question: 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.

Question: Article: The class teacher thought that hobbies were very important for every child.She encouraged all her pupils to have one, and sometimes arranged for their parents to come and see the work they had done as a result. One Friday morning the teacher told the class that those of them who had a hobby could have a holiday that afternoon to get the things they had made as parts of their hobbies ready for their parents to see the following afternoon. So on Friday afternoon, while those of the pupils who had nothing to show did their usual lessons, the lucky ones who had made something were allowed to go home, on condition that they returned before five o'clock to bring what they were going to show, and to arrange them.

"What are you doing, Tommy?" She asked."Those things must remain here until tomorrow afternoon.That's when the parents are coming to see them." "I know they are coming then, " answered Tommy, " and I will bring them back tomorrow, but my big brother doesn't want them to be out of our house at night in case they are stolen." "But what has it got to do with your big brother?" asked the teacher, "Aren't the butterflies yours?" "No, " answered Tommy."They belong to him."
