Q: Read the article and select the best answer. Article: Every year there are changes in climate in different parts of the world.Some of these changes are due to natural causes.However,some climate changes are caused by air pollution and these changes may increase. If the pollution affects the level of carbon dioxide in the atmosphere,the results are likely to be serious.There is only a small part of carbon dioxide in the atmosphere.But it has an important function in keeping the balance between radiation from the sun entering the atmosphere and radiation leaving the Earth.Some of the radiation is absorbed by the Earth and some is radiated back into the atmosphere.The carbon dioxide in the atmosphere prevents some of the radiation from leaving the atmosphere.Thus the heat remains in the atmosphere and carbon dioxide helps to prevent the temperature of the Earth from falling. If the proportion of carbon dioxide in the atmosphere is increased as a result of air pollution,the temperature of the atmosphere may rise.This might cause the ice in the North and South to melt.If this happened,the sea level could rise and parts of the Earth would be flooded.This is not quite likely but the possibility exists. There is also a fairly strong possibility that the dust level in the atmosphere will rise as a result of industrial pollution.This dust pollution will reflect sunlight back onto space.If this happens,less sunlight will reach the Earth and the temperature will fall. Another danger comes from the destruction of the Earth's vegetation such as the forest of Brazil,which is being cleared away for farmland and cities.Trees use carbon dioxide and their destruction may upset the balance of carbon dioxide in the atmosphere. Question: The main purpose of the passage is to tell us that _ . Options: A: the climate of the earth is always changing B: air pollution has greatly affected the climate of the world C: carbon dioxide has something to do with climate changes D: the climate of the world is subjected to dangers from air pollution
A: D

Q: Read the article and select the best answer. Article: Cleveland has won the distinction of being the worst city in the United States, according to a new survey. The city has high unemployment, terrible weather, heavy taxes, and ordinary sports teams, all of which have pushed it to the No. 1 position in the Forbes.com list. "Cleveland was the only city that fell in the bottom half of rankings in all nine categories. And it has been entitled with a less than endearing nickname: the Mistake by the lake," Forbes said on its website, The economic downturn hit cities across the United States last year particularly in the mid-west section of the country. Crime and unemployment secured the No. 2 spot for Stockton, which held the top position in last year's ranking. Memphis got third place thanks to its violent crime rate and the number of officials who are guilty, while the poor auto industry drove the Michigan cities of Detroit and Flint into the top five. "A lot of the cities that showed up on our list are going through hard times fight now, dealing with high unemployment, with declining producing bases. Many have experienced strong movement out of the city over the last 20 and 30 years." Despite its fine weather, Miami scored in the bottom 10 percent in commuting time, and violent crime which sent it into sixth place. "One of the biggest surprises is Miami. The good weather and no state income taxes _ some of the severe problems that Miami has related to crime as well as long commutes," Badenhausen added. Florida was followed in the poor ranking by St Louis, Buffalo, Canton, Ohio and Chicago, which has the country's highest sales tax at 10.25 percent.

Q: Read the article and select the best answer. Article: Loved and hated, but never boring. That is what people say of American writer Norman Mailer, who died late last year at the age of 84. He was the author of some of the greatest books of the 20th century. But Mailer will be remembered as much for his personality as for his writing. He was rude and bad-tempered. He violently attacked other authors and even wounded one of his six wives. However, this never stopped Mailer from being successful. People always wanted to read his books. His provocative writing style and willingness to deal with difficult subjects made his books bestsellers. "He was willing to take risks with just about everything," says the author Gore Vidal. "He had a radical imagination, a way of approaching subjects that was never boring." In a career that lasted six decades, Mailer wrote about a wide variety of subjects from history and politics to sport and celebrities. But he was most famous for writing novels and he twice won the Pulitzer Prize. His best book was The Naked and the Dead, a story about the tensions between American soldiers fighting Japan in World War II. Drawn on his own experiences as a soldier, it is a study of men at war examining their cruelty and bravery. Mailer's brilliance as an author was his ability to capture human behavior. He did so through interesting characters, realistic dialogue and rich descriptions. The author William F. Buckley said, "He created the most beautiful metaphors in the English." Mailer leaves behind more than 40 books as his literary legacy . However, he never achieved his life's goal. He wanted to write what he called the "big one", the greatest novel ever written about America. Well, at least it wasn't for a lack of trying. Question: According to the passage,_. Options: A: Norman Mailer was loved by all people B: Norman Mailer wounded other authors C: Norman Mailer wasn't successful D: Norman Mailer wrote many great books

Q: Read the article and select the best answer. Article: As late as 1800, women's only place was in the home. The idea of woman in the business world was unthinkable. Men were certain that no woman could do a good job outside her home. This was such a widely accepted idea that when the well-known Bronte sisters began writing books in 1864, they had to sign their books with men's names instead. Teaching was the first profession open to women soon after 1800. But even that was not an easy profession for women to enter because most schools and colleges were open only to men. Oberlin College in Ohio was the first college in America to accept women. Hospital nursing became respectable work for women only after Nightingale became famous. Seeing that she was not only a nurse but also a rich and well-educated woman, people began to believe it was possible for women to nurse the sick and still be "ladies". Miss Nightingale opened England's first training school for nurse in 1860. The invention of the typewriter in 1867 helped to bring women out of the home and into the business world. By 1900, thousands of women were working at real jobs in schools, hospitals and offices in both England and America. Some women even managed to become doctors or lawyers. The idea that women could work in the business world had been accepted. Question: The article is mainly about _ . Options: A: women are in the business world B: the famous Bronte sisters C: schools and colleges in America D: rights for American women
A: A
