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.

Options: (A) it is no longer used as a dye (B) it is used to cure skin cancer (C) it is a special kind of rose planted in Australia (D) it can be effective in treating skin cancer

Q: Article: The laptop is a machine which can be a mobile office;it can be used to entertain us and people can play computer games on them.One machine can perform many tasks at the same time.As technology grows,the size of the new laptop machines is _ .Now laptops are lighter,have smaller screen sizes,and perform better.Smaller screen laptops,which are more convenient to take along with,have been specially designed for professionals.Huge display screen laptops are still used by graphic designers and those who like playing computer games. Laptops are advanced machines,and they can be very expensive.When we spend much money on something,we should take good care of it.I know some people who buy a new laptop every year.The reason they do this is that the old one either is broken or has some problems which cannot be fixed.Common problems are the breaking of the screen,the breaking of joints of the laptop,display problems,and keyboard problems. Different problems will always come up with machines,and they cannot be avoided .Old machines will always have to be replaced by new ones.However,if we are more careful and handle our laptops with care,they will last for a longer period of time,and they will perform better.This is not a hard thing to do,but it will greatly increase the life and performance of laptops.
Question: We infer that graphic designers still use huge display screen laptops most probably because _ .
Options: (A) huge display screen laptops are very cheap (B) small display screen laptops are not on sale yet (C) they can see their drawings more clearly (D) they also want to play computer games

A: C

Q: Article: Ashlyn Blocker could break her arm and not know it. That's because Ashlyn, 13, can't feel pain. That might sound like a cool superpower. But without pain, everyday activities can be hazardous for Ashlyn. In fact, they could kill her. When Ashlyn was born, no one knew that she couldn't feel pain. But soon there was hints that something was wrong. When Ashlyn's teeth grew in, she almost chewed off part on her tongue. Ashlyn's parents took her to doctor for tests. The doctors discovered that Ashlyn couldn't feel pain, a condition called congenital insensitivity to pain(CIPA). Fewer than 100 people in the United States have it. There is no cure. . "Sometimes it's frustrating," she admits. But Ashlyn doesn't let anything stop her from doing things she wants to do. "I just have to be careful," she says. For years, Ashlyn didn't know anyone else who had CIPA. That made it harder to deal with her condition. "I felt alone," she says. One night she dreamed that there was a camp for kids like her. In 2011, Ashly's mom made the dream come true. She started Camp Painless But Hopeless. The camp is for children who have CIPA. Every November, they and their families spend four days together. The campers get to do daring activities like rock climbing--wearing safety equipment. Someday, Ashlyn wants to be a director at the camp so she can help others who can't feel pain. In fact, Ashlyn is already helping others. Since 2004, she has let scientists study her to learn more about her condition. What they are finding out could one day help people who suffer from the same disease. That makes her feel great. "I believe there is a reason for everything, " she says, "There is a reason for me."
Question: What can we learn about Ashlyn's illness?
Options: (A) She was born that way. (B) It is a common disease (C) It is sometimes helpful to her (D) She is getting better and better now.
