Read the article and select the best answer. Article: 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. Question: Which of the following is TRUE according to the passage? Options: A: New models of clean cars will soon replace the traditional cars B: Public transportation should replace all the private cars C: In some university, electricity is used in school buses D: It is only the government's efforts that can help solve air pollution caused by cars

Read the article and select the best answer. Article: My first performance in front of an audience was coming up soon. I tried as hard as I could to keep calm, but my heart was racing. I stared down at my sweat-covered, shaking hands. I looked up again at the audience, realizing that these were real people. They were not just my mum and dad, who would say, "Good job!" even if I missed up the whole piece. What if I had the wrong music? What if I played the wrong notes? As it turned out, I was never able to answer these questions because the spotlight   was waiting for me. I grasped my hands tightly together, drying off the sweat. Slowly I walked to the mud-brown piano in the centre of the room. It had 88  _ keys, which were waiting impatiently to be played. _ in my throat   and sat down. Slowly, I opened the music. Next, I rested my still shaking hands on the keys. As my fingers played across the keys, I was becoming more unsure of my preparation for this moment. But the memory of my year of training came flooding back. I knew that I had practised this piece so many times that I could play it backwards if asked. Although at one point I accidently played two keys instead of the intended one, I continued to move my fingers automatically . My eyes burned holes into the page in front of me. There was no way that I was going to lose my concentration. To keep this promise to myself, I leaned forward and concentrated carefully on the music. When I came to the end of the page, a warning went off inside my head: don't make a mistake when you turn the page! Needless to say, I obeyed myself with all my heart and mind, and was proud of my "page-turning" feat . I finished the rest of the piece without making a single mistake. I had finished. I had mastered the impossible. Question: Before the writer gave her first performance,   _  . Options: A: she could see nothing but her own shaking hands.

Read the article and select the best answer. Article: Zoo elephants don't live as long as those in the wild, according to a study sure to cause debate about keeping the giant animals on display. Researchers compared the life spans of elephants in European zoos with those living in Amboseli National Park in Kenya and others working on a timber enterprise in Buma. Animals in the wild or in natural working conditions had life expectancies twice than or more of their relatives in zoos. Animal care activists have urged in recent years to discourage keeping elephants in zoos, largely because of the lack of space and small numbers of animals that can be kept in a group. The researchers found that the _ life span for African elephants in European zoos was 16.9 years, compared with 56 years for elephants who died of natural causes in Kenya's Amboseli Park. Adding in those elephants killed by people in Africa lowered the median life expectancy there to 35.9 years. For the more endangered Asian elephants, the median life span in European zoos was 18.9 years, compared with 41.7 years for those working in the Burma Timber Enterprise. Median means half died younger than that age and half lived longer. There is some good news, though. The life expectancies of zoo elephants have improved in recent years, suggesting an improvement in their care and raising, but "Protecting elephants in Africa and Asia is far more successful than protecting them in Western zoos." There are about 1,200 elephants in zoos, half in Europe, researchers concentrated on female elephants, which make up 80 percent of the zoo population. One amazing thing was that Asian elephants born in zoos had shorter life spans that those brought to the zoos from the wild. Zoos usually lack large areas that elephants are used to in the wild, and that zoo animals often are alone or with one or two other unrelated animals, while in the wild they tend to live in related groups of 8 to 12 animals. In Asian elephants, baby death rates are two to three times higher in zoos than in the Burmese logging camps, and then, in... Question: Who are expected to pay more attention to the issue addressed? Options: A: Zoologists. B: Animal care activists. C: Zoo visitors. D: The public.
