[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: More than a century ago, the composer and bandleader John Philip Sousa warned that technology would destroy music, who said, "These talking machines are going to ruin the artistic development of music in this country. When I was a boy ... in front of every house in the summer evenings you would find young people together singing the songs of the day or the old songs. Today you hear these terrible machines going night and day. We will not have a vocal cord left." Music has greatly changed in the past hundred years, which has been everywhere in our world: rivers of digital melody flow on the Internet or on disc; MP3 players with forty thousand songs can be put in a back pocket or a purse. Yet, for most of us, music is no longer something we do ourselves, or even watch other people do in front of us. It has become a radically virtual medium, an art without a face. Ever since Edison invented the phonograph cylinder , people have been assessing what the medium of recording has done for and to the art of music. Sousa was a spokesman for the party of doom; in the opposite corner are the utopians , who argue that technology has not imprisoned music but liberated it. Before Edison came along, Beethoven's symphonies could be heard only in select concert halls. Now the recordings carry the man from Bonn to the corners of the earth. Glenn Gould, after renouncing live performance in 1964, predicted that within the century the public concert would disappear into the electronic air. Having discovered much of my favorite music through LPs and CDs, I am not about to join Sousa's party. Modern urban environments are often so soulless or ugly that I'm grateful for the humanizing touch of electronic sound. But neither can I accept Gould's slashing futurism. I want to be aware of technology's effects, positive and negative. Fortunately, scholars and critics have been methodically exploring this _ for many decades, trying to figure out exactly what happens when we listen to music with no musicians in the room.
Question: The author's attitude towards the recorded music may best be described as _ .
Options: (A) dissatisfied (B) defensive (C) optimistic (D) objective
Asnwer: C
[EX A]: No

[EX Q]: Article: Americans often say that there are only two things a person can be sure of:death and taxes.Many people feel that the United States has the worst taxes in the world. Taxes are the money that people pay to support their government.There are generally three levels of government in the United States:federal,state,and city;therefore,there are three types of taxes. Salaried people who can earn more than four to five thousand dollars per year must pay a certain part.It depends on their salaries.The federal government has a two-level income tax:that is,15 or 28 percent.$17 850 is the cut off.The tax rate is 15 percent below $17 850 and 28 percent above. The second tax is for the state government:New York,California,or any of the other forty-eight states.Some states have an income tax similar to that of the federal government.Of course,the percentage for the state tax is lower.Other states have a sales tax,which is a percentage charged to any item which people buy in the state.Some states use income tax and sales tax to raise their revenues(=annual income). The third tax is for the city.This tax comes in two forms:property tax(people who own a home have to pay taxes on it) and excise tax ,which is collected on vehicles in a city.The cities use this money for education,police,public works,etc. Since Americans pay such high taxes,they often feel that they are working one day each week just to pay their taxes.People always complain about taxes.They often say that the government misuses their tax dollars.They all believe that taxes are too high in this country.
