The International Space Station allows astronauts to live in space for extended amounts of time, enabling them to explore the outside universe and conduct many experiments. However, nothing like that exists for our oceans, and thanks to the high water pressure, ocean researchers are able to explore what lies undersea for very short periods of time. They are therefore never able to fully explore the deep inside areas of our oceans. However, if French architect Jacques Rougerie has his way, that will change soon. Jacqucs has designed a ship that will allow researchers to spend a long period of time observing the sea life and conducting experiments. The huge 167ft ship, named "Sea Orbiter", consists of two areas-one above the water where the scientists and crew will live, and a lower pressurized deck (甲板), where scientists will be able to spend as much time as they wish. Since it is powered by sea currents and wind, he expects it to drift (漂流) along the oceans slowly, taking about two years to circumvent the globe. Jacques will make their life as comfortable as possible in the ship. Besides being equipped with the latest sailing tools and communication equipment, the ship will also have a gym, a television and a DVD player. And these guys will not be eating freeze-dried food like astronauts. Instead, Jacques, an accomplished chef, plans on cooking them delicious meals every day. The biggest problem to this giant ship is the cost, which is expected to be over $500 million-per ship! However, Jacques, who strongly believes that the secrets of our oceans may be the key to solving global warming and a vital supply for food and medicine in the future, is confident he will be able to convince governments all over the world to help out, and expects to start construction on not one, but four or five of these amazing ships soon! |
1. Why can"t ocean researchers explore the deep oceans for a long time? A. Because they can"t stand the high water pressure. B. Because it"s too cold in deep ocean. C. Because time for experiments is too limited. D. Because it"s dangerous to observe the sea life. 2. The underlined word "circumvent" probably means_____. A. fly away B. get around C. travel through D. move into 3. From the fourth paragraph we can learn that_____. A. Jacques intends to design the ship mainly for sightseeing and traveling B. living a comfortable life helps to do the ocean research quickly C. it"s much more expensive to eat freeze-dried food D. researchers on Jacque"s ship will live more comfortably than astronauts 4. Which of the following would be the best title for the text? A. Sea Orbiterthe ship of the future B. A new way to explore the deep oceans C. A great architectJacques Rougerie D. Travel around the globe in Sea Orbiter |

Money really can"t buy happiness. According to a new survey, lawyers and __1__ well-paid white-collar workers are more likely to suffer depression. A national survey of more than 7500 professionals has found that almost one __2__ ten reported moderate (中度) to severe depressive symptoms. The legal profession had the worst result, _ 3__ almost 16 percent reporting symptoms of clinical depression (临床抑郁症). Next __4__(be) accountants and insurance underwriters, both on 10 percent. People in IT services, architecture and engineering also had depression rates above the average. The survey __5__ (conduct) by Beyondblue, an organization devoted to fighting depression, also showed that __6__ under 30 who had the __7__ (high) rates of depression were the most likely to "self-medicate" with drugs and alcohol. Beyondblue deputy chief executive and _ 8__ (psychology), Dr. Nicole Highet, said the survey was first to reveal the extent of the problem. "We often associate depression with the most socially disadvantaged and people under financial pressure, __9_ here"s a whole different group." Dr. Highet said, She said while it was difficult to know exactly __10_ made some groups more prone to depression, it was likely to be driven by work pressures. |

Every year, earthquakes are responsible for a large number of deaths and vast amounts of destruction(破坏) in various parts of the world. There are about a million quakes a year. Fortunately, however, not all of them are destructive. The intensity (强度) of an earthquake is measured on the Richter Scale, which goes from zero upward. The highest magnitude recorded to date is 8.9Major damage generally occurs from quakes ranging upwards from 6.0. The actual cause of earthquake itself is the breaking of rocks at or below the breaking of rocks or below the earth"s surface. This is produced by pressure which scientists believe may be due to a number of reasons, two of which are the changed of the earth"s crust (外壳) and continental drift(漂流). In order to minimize the damage and to decrease some of the pain resulting from earthquakes, scientists are working on ways to improve accurate prediction. Two kinds of the instruments now in use to achieve this goal are seismograph(地震仪) and tilt (倾斜) meter. The former records any shaking of the earth. Seismologists ca accurately record the exact time, location and size of an earthquake. The latter, as the name suggests, is used to record any changes in the tilt of the land. |
1. Which of the following statements is NOT true, according to the passage? |
A. The highest magnitude of earthquake recorded is 8.9 B. Major damage usually happens when the intensity of an earthquake is below 6.0 C. Scientists usually use seismographs and tilt meters to predict earthquakes now. D. Continental drift may cause an earthquake. |
2. What"s the main idea of the passage? |
A. Earthquakes can cause a lot of damage. A.Scientists are working hard to predict the earthquakes. B.The reason why earthquakes happen. C.Introduce the earthquake and its prediction. |
3. Where does the passage mot likely come from? |
A. A newspaper. B. A report C. A science magazine. D. A history book. |

Most people believe they don’t have much imagination. They are 1 . Everyone has imagination, but most of us, once we become adults, forget how to 2 it. Creativity isn’t always 3 with great works of art or ideas. People at work and in their free time 4 think of creative ways to solve problems. Maybe you have a goal to achieve, a tricky question to answer or you just want to expand your mind! Here are three techniques to help you. Making connections. This technique involves taking 5 ideas and trying to find links between them. First, think about the problem you have to solve or the job you need to do. Then find an image, word, idea or object, for example, a candle. Write down all the ideas/words 6 with candles: light, fire, matches, wax, night, silence, etc. Think of as many as you can. The next stage is to relate the 7 to the job you have to do. So imagine you want to buy a friend an original 8 ; you could buy him tickets to match or take him out for the night. NO limits! Imagine that normal limitations don’t 9 . You have as much time /space / money, etc. as you want. Think about your goal and the new 10 . If your goal is to learn to ski, 11 , you can now practise skiing every day of your life (because you have the time and the money). Now 12 this to reality. Maybe you can practise skiing every day in December, or every Monday in January. Be someone else! Look at the situation from a 13 point of view. Good businessmen use this technique in trade, and so do writers. Fiction writers often imagine they are the 14 in their books. They ask questions: What does this character want? Why can’t she get it? What changes must she make to get what she wants? If your goal involves other people, put yourself in their 15 . The best fishermen think like fish! |

Batteries can power anything from small sensors to large systems.While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves.University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient. “To provide enough power, we need certain methods with high energy density (密度) .”said Jae Kwon,assistant professor of electrical and computer engineering at MU.“The radioisotope (放射性同位素)battery can provide power density that is much higher than chemical batteries.” Kwon and his research team have been working on building a small nuclear battery,presently the size and thickness of a penny,intended to power various micro/nanoelectromechanical systems(M/NEMS) .Although nuclear batteries can cause concerns,Kwon said they are safe. “People hear the word‘nuclear"and think of something very dangerous.”he said.“However, nuclear power sources have already been safely powering a variety of devices, such as pacemakers,space satellites and underwater systems.” His new idea is not only in the battery"s size, but also in its semiconductor(半导体) .Kwon"s battery uses a liquid semiconductor rather than a solid semiconductor. “The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构)of the solid semiconductor.”Kwon said.“By using a liquid semiconductor, we believe we can minimize that problem.” Together with J .David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery.In the future, they hope to increase the battery"s power,shrink its size and try with various other materials.Kwon said that the battery could be thinner than the thickness of human hair. 1 .Which of the following is true of Jae Kwon?________ A. He teaches chemistry at MU. B .He developed a chemical battery. C .He is working on a nuclear energy source. D .He made a breakthrough in computer engineering.
2 .Jae Kwon gave examples in Paragraph 4________. A .to show chemical batteries are widely applied B .to indicate nuclear batteries can be safely used C .to describe a nuclearpowered system D .to introduce various energy sources
3 .Liquid semiconductor is used to________. A .get rid of the radioactive waste B .test the power of nuclear batteries C .decrease the size of nuclear batteries D .reduce the damage to lattice structure
4 .According to Jae Kwon,his nuclear battery________. A .uses a solid semiconductor B .will soon replace the present ones C .could be extremely thin D .has passed the final test | 完形填空 | If you wear socks on your ears, you won’t be punished. Crossing a street against a red light is another matter - it’s against the law. Laws are __ 1____ rules made by governments.

They lived together, followed the same ____3____, and worshipped the same gods. There were no formal laws. ____4____, people were guided by their customs, morals, and religion. Over time, cities began to form. Laws became more formal and were written down in legal codes. In about 1750 BC, the king of Babylon ____5_____ one of the first legal codes, the Code of Hammurabi. It listed certain crimes and told how they should be punished. The ancient Romans helped shape our modern view of law. In the 600s BC, citizens of Rome wrote down all of their basic laws on twelve bronze tablets. The Romans declared that no citizen, ____6___ the ruler, was above the law. Modern law codes are root ed in the Roman system. Such law codes are statutory, meaning they are created and changed by legislatures, not by courts. Another system of law ___7___ later in England. Before the 12th century AD., each part of England had its own rules and customs. From the 12th century onward, England became a single nation.
