Canada Canada"s multicultural environment is good for students" studies and careers. Good news: Students are allowed to take off- campus part-time jobs during their studies from last year. It"ll help pay living expenses. Students can get two-year work permits after graduation. Concerns: Only a limited number of scholar- ships are available. They rarely cover the full cost of a study programme. Useful link: www. studycanada. cn |
The UK Easier access to visas and international environment are the UK"s great attractions fox Chinese students. Good news: There many new scholarships this year, both from the government and universities, such as the Scotland International Scholarship. Concerns: Money. Money. Money. It"s expensive to study in the UK, with an average cost of 200,000 to 300,000 yuan a year. Useful link: www. educationuk. org. cn |
The US The US has always been on the top destination list for Chinese students, with its high education standards and enough scholarship. Good news:It"s easier to get a US student visa (签证) nowadays. Last year, the refusal rate was only 20 to 30 per cent, much lower than a few years before, according to US Embassy. Concerns: There"re a lot to prepare. The TOFEL, GRE... It"s longer time to apply to US universities than schools in the UK or Australia. Useful link: www. usembassychina. org. cn |

Suppose we built a robot to explore the planet, Mars.We provide the robot with seeing detector (探 测器) to keep it away from danger. It is powered entirely by the sun. Should we program the robot to be equally active at all time? No.The robot would be using up energy at a time when it was not receiving any. So we would probably program it to stop its activity at night and to wake up at dawn the next morning. According to the evolutionary (进化的) theory of sleep, evolution equipped us with a regular pattern of sleeping and waking for the same reason.The theory doesn"t deny that sleep provides some important restorative functions. It merely says that evolution has programmed us to perform those functions at a time when activity would be inefficient and possibly dangerous. However, sleep protects us only from the sort of trouble we might walk into; it doesn"t protect us from trouble that comes looking for us. So we sleep well when we are in a familiar and safe place, but we sleep lightly, if at all,when we fear that bears will nose into the tent. The evolutionary theory explains the differences in sleep among creatures.Why do cats,for instance, sleep so much,while horses sleep so little? Surely cats do not need five times as much repair and restoration as horses do.But cats can afford to have long periods of inactivity because they spend little time eating and unlikely to be attacked while they sleep. Horses must spend almost all their waking hours eating, because what they eat is very low in energy value. Moreover,they cannot afford to sleep too long or too deeply, because their survival depends on their ability to run away from attackers. |

It is hard to track the blue whale, the ocean"s largest creature which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio equipment to it is difficult and visual sightings are too unreliable to give real insight into its behavior. So biologists were delighted early this year when with the help of the Navy they were able to track a particular blue whale for 43 days monitoring its sounds . This was possible because of the Navy"s formerly top-secret system of underwater listening equipment spanning (估量) the oceans . Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies . Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures. The speed of sound in water is roughly one mile a second-slower than through land but faster than through air. What is most important , different layers of ocean water can act as channels for sounds focusing them in the same way a stethoscope (听诊器) does when it carries faint noises from a patient"s chest to a doctor"s ear. This focusing is the main reason that even relatively weak sounds in the ocean especially low frequency ones can often travel thousands of miles. |
1. The passage is chiefly about . |
A. an effort to protect an endangered marine species B. the civilian use of a military detection system C. the exposure of a U. S. Navy top-secret weapon D. a new way to look into the behavior of blue whales |
2. The underwater listening system was originally designed . A. to mark and locate enemy ships B. to monitor deep-sea volcanic eruptions C. to study the movement of ocean currents D. to replace the global radio communications network |
3. The deep-sea listening system makes use of . |
A. the complex technology of focusing sounds under water B. the capability of sound to travel at high speed C. the special quality of layers of ocean water in sending out sound D. low-frequency sounds traveling across different layers of water |
4. It can be inferred from the passage that . |
A. new radio equipment should be developed for tracking the endangered blue whales B. blue whales are no longer endangered with the use of the new listening system C. opinions differ as to whether civilian scientists should be allowed to use military technology D. military technology has great potential in civilian use |
5. Which of the following is true about the U. S. Navy underwater listening network ? |
A. It is now partly used by civilian scientists. B. It has been replaced by a more advanced system. C. It became useless to the military after the cold war. D. It is necessary in protecting endangered species. |

Some researchers claim that people"s personalities can be classified by their blood types. If you have blood type O, you are a leader. When you see something you want, you strive to achieve your goal. You are passionate, loyal, and self-confident, and you are often a trendsetter. Your enthusiasm for projects and goals spreads to others who happily follow your lead. When you want something, you may be ruthless about getting it or blind to how your actions affect others. Another blood type, A, is a social, "people" person. You like people and work well with them. You are sensitive, patient, compassionate, and affectionate. You are a good peacekeeper because you want everybody to be happy. In a team situation, you resolve conflicts and keep things on a smooth course. Sometimes type As are stubborn and find it different to relax. They may also find it uncomfortable to do things alone. People with type B blood are usually individualists who like to do things on their own. You may be creative and adaptable, and you usually say exactly what you mean. Also you can adapt to situations, you may not choose to do so because of your strong independent streak. You may prefer working on your own to being part of a team. The final blood type is type AB. If you have AB blood, you are a natural entertainer. You draw people to you because of your charm and easygoing nature. ABs are usually calm and controlled, tactful and fair. On the downside, though, they may take too long to make decisions. And they may procrastinate, putting off tasks until the last minute. |

With only about 1, 000 pandas left in the world, China is desperately trying to clone (克隆) the animal and save the endangered species(物种). That"s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called "Noah"s Ark". Noah"s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M"s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future. It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years. This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete. "The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available panda eggs could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it"s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort," adds Kraemer, who is one of the leaders of the Project at Texas A & M, the first-ever attempt at cloning a dog. "They are trying to do something that"s never been done, and this is very similar to our work in Noah"s Ark. We"re both trying to save animals that face extinction. I certainly appreciate their effort and there"s a lot we can learn from what they are attempting to do. It"s a research that is very much needed." |
