In the last few years the Internet has become a widespread phenomenon  around the world. People have started to use the computers just like they used to watch TV. Whenever we get hungry, we simply order a pizza through the Internet and while we are waiting for the food, we can send an important business e-mail concerning some sales for tomorrow. It is, in fact, very comfortable to just simply sit down and have a chat with somebody from South Africa about fishing and get some important advice. Sometimes when you are sad and are feeling lonely, if you go on the Internet, you can find good entertainment that will keep you busy. To make a long story short, we just don't have the time to communicate with people in person anymore. Besides, there is so much information easy to get on the Internet that when we start surfing, we find it hard for us to get away from the computer. There are a lot of people who are addicted  to TV and watch it 5 to 7 hours a day, while recently addiction to the Internet has become a very serious problem. You might think that these kinds of things could never happen to you, but it is not really true. To prevent yourself from getting addicted, the most important thing is to make sure that you are not spending too much time in front of the screen. Although it might seem to be easy to pull yourself away from the Web, it is simply not the case. You might have to make an effort to place some limits  on yourself. To avoid getting addicted to the Internet, we should  _  . A) watch TV more hours a day instead B) limit our time in front of the screen C) communicate with people face to face D) entertain ourselves in other ways

When we talk about intelligence,we do not mean the ability to get a good score on a certain kind of test,or even the ability to do well in school. These are at best only indicators of something larger,deeper,and far more important. By intelligence we mean a style of life,a way of behaving in various situations. The true test of intelligence is not how much we know to do,but how we behave when we don't know what to do.  The intelligent person,young or old,meeting a new situation or problem,opens himself up to it. He tries to take in with mind and senses everything he can about it. He thinks about it,instead of about himself or what it might cause to happen to him. He grapples with it  ly,imaginatively,resourcefully ,and if not confidently,at least hopefully;if he fails to master it,he looks without fear or shame at his mistakes and learns what he can from them. This is intelligence. Clearly its roots lie in a certain feeling about life,and one's self with respect to life. Just as clearly,unintelligence is not what most psychologists seem to suppose,the same thing as intelligence,only less of it. It is an entirely different set of attitudes.  Years of watching and comparing bright children with the not-bright,or less bright,have shown that they are very different kinds of people. The bright child is curious about life and reality,eager to get in touch with it,embrace it,unite himself with it. There is no wall,no barrier,between himself and life. On the other hand,the dull child is far less curious,far less interested in what goes on and what is real,more inclined to live in a world of fantasy. The bright child likes to experiment,to try things out. He lives by the maxim that there is more than one way to skin a cat. If he can't do something one way,he'll try another. The dull child is usually afraid to try at a11. It takes a great deal of urging to get him to try even once;if that try fails,he is through.  Nobody starts off stupid. Hardly an adult in a thousand,or ten thousand,could in any three years of his... The writer believes that "unintelligence" is_. A) similar to intelligence B) 1ess than intelligence C) the common believes of most psychologists D) a particular way of looking at the world

If a noisy neighbor is blasting music at all hours of the day and night, drowning out your phone conversations and interrupting your sleep, you can call the police. But what is a whale to do? Natural noise from waves, wind, rain and even earthquakes is common in oceans. Unfortunately, man-made noise from oil and gas drilling, sonar, and ships is also present. Low frequency noise has doubled off the California coast every decade since the nineteen sixties. The main reasons are ships' propellers . They not only generate continuous low frequency sound, some propellers cavitate , which means they create air bubbles that collapse, creating loud popping sounds. Whales use low frequency calls to communicate across thousands of miles of ocean. They are threatened by noise pollution because it can prevent them from contacting each other and from locating their foods. Endangered humpback and right whales, which use fibrous baleen to strain food from the water, are the most at risk. Scientists studying right whales off Canada's east coast have discovered that whales are sending louder calls through the water to make themselves heard. Because they invest more energy in making calls, they have less energy available for finding food and mating. Other scientists measuring whale calls against background noise pollution have discovered that right whales have lost about eighty percent of their normal communication area. This could seriously affect survival of this already threatened species. Scientists don't have badges and guns, but they are trying to correct the noise pollution problem. By tracking ships and marine mammals and understanding how noise travels, they are creating sound maps. They hope to get shipping lanes moved so that the noise pollution ships create will not overlap with areas most important to the whales. According to the description of whales, we can know that   _  . A) The noise made by the ships has a bad effect on the area where whales live. B) Whales can communicate with each other by diving into the deep water. C) Whales cannot find mates because they don't have enough energy. D) The communication between whales is through low frequency calls

Competition between international universities is heating up, as China grows as one of the largest exporters of students aiming to study abroad. "Lots of universities are becoming more and more aggressive to attract Chinese students. Every day I receive contacts from universities in the  US expressing the desire to come to China to recruit students," said Frank Joseph, a commercial officer from embassy of the United States. One key reason why more Chinese students are able to study abroad is the economy: With China's boom within the past decade, more families have the financial wherewithal  to send their children to international universities. There will be a total of 200,000 family-funded Chinese students studying overseas in 2009, up 20 percent from last year, said Wu Zaofeng, deputy secretary general of China Education Association for International Exchange. International institutions, Joseph said, are also facing increasingly tough financial situation with a shortage of domestic students and a drop in government subsidies . Students, especially in the US are paying high tuition fees and living expenses. Chinese students with money to spend, according to experts, can fill up the gap. Students on average spend 150,000 yuan to 200,000 yuan every year studying in US, according to statistics from the US Institute of International Education. During 2007-2008, there were approximately 81,000 Chinese students studying in the US, up 19.8 percent from 2006. Representatives from approximately 60 universities from the United States are planning to arrive in Beijing this weekend to attract more Chinese students at this year's fair. Besides the US, many other countries are also vying  to enroll Chinese students. Post-study work visa put out by British government allows all international students completing a UK degree qualification to apply for a visa to stay on and look for work in UK for up to 2 years. Being the third most popular destination for international students next to the US and the UK, France has set up two... Why are more Chinese students able to study abroad? A) Because they can't go to the best universities at home. B) Because their families have enough money to send them to international universities. C) Because they want to win the scholarship of foreign universities D) Because the Chinese students enjoy following others and they want to be independent.
