Too many cars have created a lot of serious problems in our world. Besides congestion , accidents and fast fuel consumption , cars are responsible for a good part of air pollution in big cities. All the time, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, causing disease and even death. Last winter, car fumes formed heavy smog over Beijing, making the sky gloomy for weeks and deteriorating people's health. One possible solution is to design and develop clean cars and clean fuels. In Tsinghua University, campus buses are driven by electricity. In Beijing some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars to completely replace the traditional ones. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not use private cars. And the total number of cars in big cities will reduce greatly. On the whole, the elimination of air pollution needs the co-efforts from the government, the public and the environments. This problem will be solved only with the help of science and technology. What is the best title of this passage? A) Air Pollution and Cars B) Air Pollution C) the Cause of the Pollution D) Ways to Solve the car Problem

One August afternoon, Richard Allen dropped off his last passenger, Mrs. Carey. Lifting two grocery bags, he followed her across the yard and stood on the step of her house. Glancing up, he saw a large wasp nest under the roof. Allen had heard that wasps can become more likely to sting(sting, stung, stung)in summer. He mentioned this to Mrs. Carey, who had opened the door. "Oh, they don't bother me," she said lightly. "I go in and out all the time." Anxiously, Allen looked at the nest again-to see the wasps flying straight at him. "Hurry!" he shouted to Mrs. Carey. "Get in!" She stepped quickly inside. Allen ran for his mini-bus. Too late; they were upon him. Just as he jumped aboard, half a dozen red spots showed on his arm, and he felt more on his back and shoulders. As he was driving down the road, Allen felt as if something was burning at the back of his neck, and the "fire" was spreading forward toward his face. An immediate anxiety took hold of him. Allen knew that stings could cause some persons to die. But he had been stung the previous summer and the after-effects soon passed. However, what he didn't know was that the first sting had turned his body into a time bomb waiting for the next to set off an explosion. Miles from the nearest medical assistance, Allen began to feel his tongue thick and heavy and his heartbeat louder. Most frightening, he felt his breathing more and more difficult. He reached for the radio mike ,trying to call the mini-bus center, but his words were hardly understandable. Signals were also poor that far out. He knew a rescue team was on 24-hour duty at the Amherst Fire Department's north station. So his best chance was to make a run for it. Rushing down the mountain, Allen tried not to panic, focusing his mind on each sharp turn. He was almost through the last of them when he felt sure he was going into shock .Just then he reached for the radio mike again. "Call fire station," he shouted, concentrating to form the words. "Emergency. Bee sting. Emergency. There in ten... Allen failed at his first attempt to send his message to the mini-bus center because _ . A) he was in a state of shock B) his radio equipment was poor C) he was unable to speak clearly D) no one was on duty

Ques: Most people are afraid of bees. Anyone who's been stung by one quickly learns to avoid bees whenever possible. I learned that lesson when, as a child, I ran into a beehive. Dozens of bees attacked, stinging me all over my body. It was a painful incident, but I was lucky. Those bees weren't Africanized, or "killer" bees. Killer bees are extremely aggressive . When they become upset, they attack. And just about anything like noises, shiny objects, dark clothes can all cause killer bees to attack. When one killer bee stings a victim, it gives off a chemical. Other bees smell this and go into attack mode. The whole hive will aggressively attack the unfortunate victim. Killer bees will also run their victims for up to a quarter of a mile. Some victims have tried to keep away from the bees by jumping into water. But killer bees will wait for them to come up and then continue their attack. Killer bees can be found in South America and the southern prefix = st1 /United States. They were created when, in 1956, scientists brought African bees toBrazil. African bees were known to increase coffee production. Some scientists thought that these bees might increase honey production, too. So inBrazil, they tried crossbreeding the African bees with European honeybees. The results were _ The new Africanized bees actually decreased honey production and were very aggressive. Scientists tried to separate the bees, but some of them escaped and began rapidly spreading north. Since then, killer bees have been causing damage to humans, animals and the American honey industry. Over the years, these aggressive killer bees have caused nearly 10,000 people to die. What's the best thing to do if you are attacked by killer bees? Fortunately, killer bees don't fly very fast. Most healthy adults can outrun them. Experts advise you to cover your face and run! We can infer from the passage that _ . A) killer bees will take the place of European bees before long B) killer bees are sure to increase the production of coffee C) it is difficult to get rid of killer bees D) killer bees have caused great harm to the people there

Ques: American culture is unique because it is formed and developed under certain conditions. The major factors contributing to the making of this new nation and the forming of a new culture are the hard environment, ethnic diversity (;) and plural religion, which is quite different from other nations in the world. What is more, these elements are still influencing the American culture. The early immigrants who were English Puritans settled down in northeast part of America from 1607 to 1892. Frontiers were pushed further west. The frontiersmen looked for a land of rich resources and a land of promise, opportunity and freedom. Actually they looked for a better life. So individualism , self-reliance, and equality of opportunity have perhaps been the values most closely associated with the frontier heritage of America. In history, people from different countries in the world rushed to America three times. They brought their own culture to America and later on, different cultures were mixed together. Thus the unique American culture was formed, a common cultural life with commonly shared values. The fundamental American belief in individual freedom and the fight of individuals to practice their own religion is at the center of religious experience in the United States. The great diversity of ethnic backgrounds has produced religious pluralism ; almost all of the religions of the world are now practiced in the United States. Nowadays, we can see the continual influence of the three elements in the current American society. American family is typically parents and their unmarried children. Middle-aged and elderly people generally do not live with their married children. The people in America have a very strong desire to start a new life in a new place. Quite a number of people change residences every year. The average American moves fourteen times in his lifetime. We can learn from this article that _ . A) the population of the United States includes a large variety of ethnic groups B) the early immigrants brought about the unique American culture C) people in the world once rushed to America because of its unique culture D) the American family members don't get along well with each other
