"For example, Ainu, a language in Japan, is now seriously threatened, with only 10 native speakers left," said lead study author Tatsuya Amano at the University of Cambridge in England. The scientists found that 25 percent of the world's languages are threatened. After identifying where the endangered languages were, they looked for any environmental and social or economic factors those languages might have in common, such as rugged terrain or rapid population growth. "We found that at the global scale, language speaker declines are strongly linked to economic growth-that is, declines are particularly occurring in economically developed regions," Amano said. One important implication of this new study "is that languages in the tropics and Himalayan region are likely to be increasingly threatened in the near future, because these regions still have many local indigenous languages with a small number of speakers, and at the same time are experiencing rapid economic growth," Amano said. Economic growth may endanger languages for a variety of reasons. For instance, speakers of endangered languages may view another more dominant language as offering economic opportunities, and thus forego their own languages. There are other important factors that might endanger languages, the researchers said. For instance, policies regarding how languages are used and taught in schools can be very different among countries and even within each country, and these factors may explain more detailed patterns in language endangerment. Amano suggested it could be possible to forecast future threats to linguistic diversity. "There exists detailed information on projected future changes in the environment, economies and climates," Amano said. "Using such information, together with the findings of this study and further analysis, we would like to understand what will happen to the world's languages, where it will happen and which languages will be... Question: What may endanger the languages most according to Amano? Options: A: The diversity of society. B: The decline of the population. C: The development of economy D: The improvement of the environment.

Most of the teachers are young and sociable,and there are a lot of parties there. Korea is usually the place most people go,because they have the most benefits and highest salaries by working only twenty hours a week. Japan is also a good choice,but only if you stay there for a long time will you save some money. China is a new rising star and lots of people are going there. Like Japan,the pay is quite good,but the cost of living in China is much cheaper. You can save a sizable amount and complete all your loans back home. Besides,Chinese people are enterprising and you can learn a lot from them. In China,Taiwan is a good place to go,especially for females who want to earn much,but there are not many adult classes offered. The Middle East offers very high salaries and great packages for teachers,all of which is tax free. However,you must be a certified teacher and have a few years' experience if you want to teach there. Most of the people who tend to teach there are older and more conservative,so they don't expect a party scene. Italy and Spain are two beautiful countries where you can try your fortune. Fashion industry in Milan would love to hire wellknown Englishspeaking people to work with international models and designers. Tourism is another industry in these countries,where English knowledge is useful. Moreover,by teaching in Europe you have the ability to travel every weekend to a new country and visit a new culture besides a good salary. Europe has a lot to offer.

Q: Read the article and select the best answer. Article: In the past ten years, many scientists have studied the differences between men and women. And they all got the same answer: The sexes are different, because their brains are different. And this, the scientists say, makes men and women see the world in different ways. Boys, for example, generally are better than girls at mathematical ideas. Boys also generally are better than girls at the kind of hand and eye movements necessary for ball sports. Girls, on the other hand generally start speaking earlier than boys. And they generally see better in the dark than boys and are better at learning foreign languages. What makes men and women better at one thing or another? The answer is the brain. The brain has two sides connected by nerve tracks. The left side generally is used for mathematics, speech and writing. The right side is used for artistic creation and the expression for emotions . In men and women, different areas in each side of the brain develop differently. In boys, for example, it's the area used for mathematics. In girls, it is the area used for language skills. Another interesting difference is that the two sides of a man's brain are connected by a smaller number of nerves than the two sides of a woman's brain are. Question: 60. The number of nerves connecting the two sides of the brain in men _ . Options: A: is the same as women's B: is different from women's C: is larger than women's D: is twice as large as women's
A: B

Q: Read the article and select the best answer. Article: "How lucky you are to be a doctor..." Anyone who's a doctor is right out of luck, I thought. _ You may think I want to change my job. Well, at the moment I do. As one of my friends says-even doctors have a few friends-it's all experience. Experience! I don't need such experience. I need a warm, comfortable, undisturbed bed of my own. I need it badly. I need all telephones to be thrown down the nearest well, that's what I need. All these thoughts fly round my head as I drive my Mini through the foggy streets of East London at 3:45 a.m. on a December morning. I am a ministering angel in a Mini with a heavy coat and a bag of medicines. As I speed down Lea Bridge in the dark at this horrible morning hour, the heater first blowing hot then cold, my back aching from the car-seat, I do not feel like a ministering angel. I wish I were on the beach in southern France. Call me a bad doctor if you like. Call me what you will. But don't call me at half past three on a December morning for an ear-ache that you have had for two weeks. Of course, being a doctor isn't really all bad. _ . Once in a while people are ill, once in a while you can help, once in a while you get given a cup of tea and rock-hard cake at two o'clock in the morning-then you worry if you have done everything. But all too often 'everything' is a repetitious rule: look, listen, feel, tap, pills, injection, phone, ambulance, away to the next. And then there is always the cool, warm voice of the girl on the switchboard of the emergency bed service who will get your patient into hospital for you-the pleasant voice that comes to you as you stand in the cold, dark, smelly, dirty telephone box somewhere in a dangerous section of town. Oh, it has its moments, this life does. Question: According to the sentence "Anyone who's studying medicine should have his head examined," we know that _ . Options: A: a medical student should have a very good memory B: a doctor must be mentally strong so that he can meet any difficult situation C: the writer thinks that those who want to be doctors are crazy D: to be a doctor is a challenge for people's mental health
