[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: "Wake up. Alicia is waiting for you outside," my mother called from the kitchen. My mother didn't like me going for this weekend to my friend's house in the mountains. "I trust you, but I don't trust the people out there," she said seriously. "I'm going to be fine," were my last words before closing the door of the Jeep. The vehicle went along the dusty road and my mother grew smaller in the distance. The trip over the rough road was uncomfortable. It was scary to climb the steep hills surrounded by great pines. After a long trip we finally arrived at the house. From the moment I got there I knew I would forever love the house. It was decorated like an old country home. My room was small, yet set up nicely. That night I went to sleep early, not because I didn't want to continue my search, but because I was tired after the long trip. In the morning, the singing of the birds woke me up. The light was just getting through the window. A strong smell of baking and fresh coffee came from the kitchen. I wandered around looking for a living soul, but the house was empty. I had the whole day to myself; my friend had gone hiking. I didn't want to go with her. The main reason for this trip was to spend some time alone to think about the events happening in my life. After an icy shower, my energies were at their fullest. With basket in hand, I started my hunt. I did not mind walking alone; it was a wonderful feeling to be in contact with nature for the first time. The sound of the water running through the rocks gave me great peace. I never felt such independence in my soul before.
Question: How did the author find the trip to her friend's house?
Options: (A) Interesting and impressive. (B) Interesting and comfortable. (C) Easy and exciting. (D) Rough but very exciting.
Asnwer: B

[EX Q]: Article: Australia is the largest island in the world. It is a little smaller than China. It is in the south of the earth. Australia is big, but its population is small. The population of it is nearly as large as that of Shanghai. We cannot believe it is such a big country with so small population! Enough laws have been made to fight against pollution. The cities in Australia have little air or water pollution. The sky is blue and the water is clean. You can clearly see fish swimming in the rivers. Plants grow very well. Last month we visited Perth, the biggest city in Western Australia, and went to a wild flowers. Exhibition In spring every year Perth has the wild flower exhibition. After visting Perth, we spent a day in the countryside. We sat down and had a rest near a path at the foot of the hill. But what we saw made us pick up all our things and run back to the car as quickly as we could--there were about three hundred sheep coming towards us down the path! Australia is famous for its sheep and kangaroos. After a short drive from any town, you will find yourself in the middle of white sheep. Sheep ,sheep, everwhere are sheep.
