Running like the wind, roaring like thunder, tigers have long been feared and respected as a king of the animal world. But last week a report said that there are no more than 30 wild tigers left in south China. This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund. The South China tiger, also known as the Chinese tiger, is native to southern China. In the 1950s, there were over 4,000 tigers found in mountain forests in the country. But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species. Sixty-six of the big cats can be found in the cages of a dozen zoos around China. But they are nothing like their wild cousins. They have lost their natural skills such as hunting and killing. If they were set free they could not look after themselves. "Breeding has damaged the quality of the species," said Pei Enle, deputy director of the Shanghai Zoo. To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa. Four of them have already arrived. Progress has been made as two elder tigers have recovered some of their instincts and can hunt wild animals by themselves at the African base. "South Africans are very experienced in reintroducing big animals to the wild. The country has very good natural conditions for the tigers to learn in," said Lu Jun, office director of the National Wildlife Research and Development Centre. "We tried in Fujian Province, but it was not successful as there was not a complete eco-chain and there was a lack of space." The tigers should return to China in 2009 when the reservations in Fujian are ready. By saying " but they are nothing like their wild cousins", the writer means that _ . A) they are no longer feared by other wild animals B) they don't know how to hunt or kill C) a complete change has resulted in the species because of breeding D) to reintroduce them into the wild has become an urgent task

(Question)
I usually doubt about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago.While any of these statements might be true, they are practically impossible to prove scientifically. Still, 1 was struck by a report which concluded that today's children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children between 9 and 17 have a higher level of anxiety today than children who were treated for mental illness 50 years ago. Why are America's kids so stressed? The report cites two main causes: increasing physical isolation brought on by high divorce rates and less involvement in community, and a growing perception that the world is a more dangerous place. Given that _ , adults can still do plenty to help the next generation to cope. At the top of the list,nurturing is a better appreciation of the limits of individualism. No child is an island. Strengthening social ties helps build communities and protect individuals against stress. To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your family will thank you later.They will then have more time for face-to-face relationships, and they will get more sleep. Limit the amount of virtual violence your children are exposed to. It's not just video games and movies; children see a lot of murder and crime on the local news. Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale. Make exercise part of your daily routine. It will help you deal with your own anxieties and provide a good model for your kids. Sometimes anxiety is unavoidable,but it doesn't have to ruin your life. What does the author thinks of the conclusion that people in America are unhappier than 50 years ago? A) Surprising B) Confusing C) Illogical D) Questionable

Ques: Have you ever imagined what human beings will look like in the future? Well, now you don't have to. According to AsapScience, a Canada-based video channel that touches on many different science topics, humans will be very different creatures 1,000 years from now. Artificial intelligence, genetic engineering and climate change will work together to change our bodies greatly, according to a video recently published by the channel. We could, for instance, develop red eyes as our DNA changes, and have darker skin because of global warming. The video painted a picture of a future world in which our bodies are part human, part machine. Nanobots, or tiny robots, will be put into our bodies, improving our abilities. "No longer will we be limited by our own physiology. We will truly become a mixture of biology and machine on the inside," says the video. Meanwhile, designer babies will cause future generations to grow into intelligent, attractive people. As global warming takes hold, humans will also be skinnier and taller, as this body shape deals with heat better. In fact, Cadell Last, a researcher at the Global Brain Institute located in Belgium, believes change may happen even faster than this. As he said in a paper recently published in Current Aging Science, mankind is already going through a major evolutionary change. In less than four decades, Last claims, we will live longer, have children in old age and need artificial intelligence to finish daily tasks. "Your 80 or 100 is going to be so radically different than your grandparents," Last said. Instead of living fast and dying young, he believes humans will live slow and die old. "The biological clock isn't going to be around forever," he added, and said that people could pause it for some time using future technology. Just a few hundred years ago, most humans were working in the fields, while nowadays more and more are getting an education. These are just predictions, and no one can be sure how human beings will evolve in the future. But with such large... Which of the following would Cadell Last probably agree with? A) Future babies will be designed according to their grandparents' wishes. B) Our increasing dependence on artificial intelligence will threaten our survival one day. C) Future technology will pause our biological clocks so that humans live slower and longer. D) In less than four decades, humans will have a sudden genetic change that will make us rely on artificial intelligence.
Ans: C
Ques:In the last fifty years, a lot of people have left Europe and gone to live in Australia. One of them was a Hungarian man. He lived in Australia for quite a long time, and he had a lot of good friends there. He always said to them, "Australia is beautiful, but Hungary is beautiful, too." Then one year he said to his friends, "I'm going to go back to Hungary to visit my home town." All his friends said to him, "We want to go with you, because you often say Hungary is a beautiful country, and we want to visit it." The Hungarian Australian took his friends from Sydney to Rome in a big plane, and then they went from Rome to Budapest in a train as they wanted to see the mountains, and the villages and the towns. They stayed in Budapest nearly a week, and they liked it very much. One day they went to the zoo in Budapest and saw two kangaroos there. These Australians were very happy because kangaroos were from their home town. They said to them, "Come here, old friends! Come and see your Australian brothers!" But the kangaroos did not move. But then the Hungarian Australian spoke to them in Hungarian, "Come here!" he said, and both of the kangaroos ran to him. The other Australians laughed and said, "Look at that. They're Australians, but they only know Hungarian!" Kangaroo is a kind of famous _ in Australia. A) animal B) tree C) language D) plant
