Task 1 Read the passage. Write True or False for the statements.Television can make you hungryWatching T.V. can be hungry work, especially nowadays when there are more and more programmes about food: cooking competitions, cake baking shows the choice is huge!In the U.K., the Great British Bake off is a television competition where people bake cakes every week. If your cake isn’t good enough you leave the show! The people who win the competition are famous all over the country.Bake off is one of the most popular shows on television at the moment and at least twenty other countries around the world now show similar programmes.It’s no surprise that we all love to watch people make cakes. The question is: do we love to spend time in the kitchen ourselves? It seems that although more and more people watch television shows about cooking, fewer people cook or bake on a daily basis. Most British people buy their meals and cakes readymade from the supermarket. Perhaps they are too bus watching television to spend time cooking...1. There are a lot of programmes about food on the T.V.A 正确B 错误
3. Every citizen all cares about national _ ，but the level is limited ，the superiority and limitation both lie in it .A. assets B. races C. assess D. asset
Task 3 Read the passage. Fill in the blanks with no more than 3 words.Are you meeting a British person for the first time? Here's what to do to get off to a good start...1. Smile! If you look friendly and interested, people will want to talk to you.2. British people usually shake hands when meeting for the first time, saying "Nice to meet you".3. Ask questions. Find out something you both have in common. Maybe you and your new friend both love pizza or cats or have the same favourite computer game. You won't know until you ask!4. If you can't think of anything to say, then talk about the weather. Everyone knows that British people enjoy talking about this topic. There is always something to say!1. It's important to smile and look _________ when you meet people for the first time.2. When British people meet for the first time they usually _________.3.

Designs on life Even if you’’re thinking big, you usually have to start small. It is especially true for a group of Swiss students who found that big means counting to infinity. The team was drawing up a blueprint for the world’’s first counting machine made entirely of biological parts. Although they had their sights on loftier numbers, they opted to go no higher than two. If the plan worked, it would be a proof-of-principle for a much larger tallyingdevice(计算装置). The group, from the Federal Institute of Technology (ETH) in Zurich, was one of 17 teams presenting their projects at the first international Intercollegiate Genetically Engineered Machine (IGEM) competition, held at the Massachusetts Institute of Technology (MIT) in Cambridge on 5 and 6 November. The event attracted students from all over the world to design and build machines made entirely from biological components such as genes and proteins. They drew up grand designs for bacterial Etch-a-Sketches, photosensitive t-shirts, thermometers and sensors. And if none of the designs succeeded completely, that was more because of the limitations of the new-born science of synthetic biology than any lack of enthusiasm, creativity or hard work.Synthetic biology Synthetic biology aims to merge engineering approaches with biology. Researchers working at the most basic level are copying simple biological processes, such as the production of a protein from a gene. They break the process down into its component elements, such as a gene and the pieces of DNA and other molecules that control its activity. They then string these elements together to build a module they know will behave in a particular way ― say, oscillate between producing and not producing a protein, or produce a protein that can switch another module on or off. It is these kinds of components― oscillators (震荡器) and switches― that engineers order from suppliers and link together to build more complex electronic circuits and machines. Synthetic biologists are trying to develop a similar armoury of biological components, dubbed BioBricks, that can be inserted into any genetic circuit to carry out a particular function. Scientists at MIT have established a Registry of Standard Biological Parts, a catalogue of BioBricks that theoretically can be ordered and plugged into a cell, just as resistors and transistors can be ordered and plugged into electronic circuitry. But it is hard to find scientists who are trained and interested in both biology and engineering to fuel the development of this new science. So, like true engineers, the founding synthetic biologists are trying to build their future colleagues from the ground up. To do so, they have commandeered a time-honoured engineering tradition: the student competition. The IGEM event began life as a project class for MIT students in 2003. Last year, it was thrown open to other US universities, and this year it went international. The organizers hope to attract 30 to 50 teams next year, including some from Asia.Competitive culture Much like the robot competitions that tap into students’’ desire to build something cool, the IGEM jamborees (国际性少年大会) fire the participants’’ natural curiosity ― hopefully encouraging biologists to learn something from engineers, and vice versa. "If you want to make something in this field, you can’’t just get some glue out and stick two cells together," says Randy Rettberg of MIT, who organized the competition. "You have to learn some biology to do it, and it’’s easy to do that during the competition because you know exactly why you’’re doing it."This year, the teams presented an eclectic selection of designs. Students from the University of Cambridge, UK, tried to make a circuit that could control the movement of Escherichia coli bacteria. They aimed to engineer the bacteria to contain a switch governing their sensitivity to the sugar maltose. With the switch off, the microbes would ignore the sugar. Tripping the switch would make the bacteria sensitive to the sugar and induce them to move towards it. In the end, the group ― like almost every other entrant ― had trouble completing assembly of its genetic parts in time. Many of the other students also tackled problems related to bacterial communication and motion. The team from Pennsylvania State University designed a bacterial relay race, which it hoped would bring synthetic biology into the realm of sports ― an innovation that won it an award for the Best New Sport at the end of the competition. A team from the University of Oklahoma’’s Advanced Center for Genome Technology in Norman tried to exploit the sugar arabinose as an engine to drive bacterial motion. Teams from the University of Toronto and the University of California, San Francisco, built concepts for bacterial thermometers; and groups from Harvard, Toronto and Princeton designed bacterial illustrators and Etch-a-Sketches. Detection and sensing were also popular, with groups from Davidson College and MIT focusing in this area. And a lab at the California Institute of Technology tackled a problem raised at last year’’s event: designing biological memory. Students from the University of Texas demonstrated the world’’s first bacterial photography system. The team engineered a plate of E. coli so that they would respond to light and has since used the invention to take numerous photos, including shots of the group’’s adviser, Andrew Ellington.Piece by piece As well as helping students to bridge the divide between disciplines, the competition gave them firsthand experience of life in the lab. All hit obstacles assembling their parts into coherent devices. It is still difficult to dissect the different genetic components of the circuits, stitch them together and get them to work in live cells. As Emanuel Nazareth reported, the students all learned one hard truth: "You can never allocate enough time for assembly." This hints at a larger problem in synthetic biology. The field aims to build up a library of parts that can be interchanged in circuits with minimal effort. But that goal is not yet a reality as DNA sequencing and assembling technologies are still a bit too expensive and complex. "We’’re not organized at the community level around fabrication," says MIT’’s Drew Endy, one of the founders of the field and of the Registry of Standard Biological Parts. These difficulties need to be overcome before biological components will be as easy to deploy as their engineering counterparts. Another learning experience was the reminder that, even stripped down to its basic components, biology can be complex and unpredictable. A team from the University of California, Berkeley, for instance, tried to design an entirely new way for cells to communicate. This is a potentially important because it would enable cells to send and receive information, forming interlocking cell circuits instead of relying on simple gene circuits built in single cells. The team hoped to exploit a natural method used by bacteria to exchange genetic information. In this, two bacteria connect their respective cell walls together using a structure called a pilus(菌毛). The group managed to trigger the connection response with synthetic circuits. But the bacteria turned out to be so eager to join up that they did so in huge bunches― and once they did, it was hard to separate them. "They don’’t really conjugate one at a time," said team spokeswoman Melissa Li. "They can go, but they can’’t stop."The living end As Rettberg points out, there are a lot of sceptics. "There’’s a big question, which is: can you build simple biological systems out of interchangeable parts and make them work in living cells " he says. "We think you can, but there’’s a lot of people who think the other way and say biology is simply so complex you can’’t do it." Given these concerns, it is no surprise that researchers have decided to keep things as simple as possible. As Robin Künzler said in introducing the project: "In the beginning we talked about counting to infinity, but we thought maybe we’’d start by counting to two." Despite this narrowed scope, the students faced a formidable challenge. They designed a series of devices: the first takes in a signal, which is then passed to an event processor. This processor ― a genetic circuit ― splits the signal into two components. A third circuit does the counting and generates a read-out.A group of Swiss students designed the world’’s first counting machine made entirely of biological parts. A．YB．NC．NG

Imagine a mass of floating waste is two times the size of the state of Texas. Texas has a land area of more than 678 000 square kilometers. So it might be difficult to imagine anything twice as big. All together, this mass of waste flowing in the North Pacific Ocean is known as the Great Pacific Ocean Garbage Patch. It weighs about 3 500 000 tons. The waste includes bags，bottles and containers—plastic products of all kinds.The eastern part of the Great Pacific Ocean Garbage Patch is about l 600 kilometers west of California. The western part is west of the Hawaiian Islands and east of Japan. The area has been described as a kind of oceanic desert，with light winds and slow moving water currents. The water moves so slowly that garbage from all over the world collects there.In recent years，there have been growing concerns about the floating garbage and its effect on sea creatures and human health. Scientists say thousands of animals get trapped in the floating waste，resulting in death or injury. Even more die from a lack of food or water after swallowing pieces of plastic. The trash can also make animals feel full，lessening their desire to eat or drink.The floating garbage also can have harmful effects on people. There is an increased threat of infection of disease from polluted waste，and from eating fish that swallowed waste. Divers can also get trapped in the plastic.Its existence first gained public attention in l997. That was when racing boat captain and oceanographer Charles Moore and his crew sailed into the garbage while returning from a racing event. Five years earlier，another oceanographer learned of the trash after a shipment of rubber duckies got lost at sea. Many of those toys are now part of the Great Pacific Ocean Garbage Patch.In August，2009，a team from the University of California，San Diego became the latest group to travel to it. They were shocked by the amount of waste they saw. They gathered hundreds of sea creatures and water samples to measure the garbage patch’s effect on ocean environment.【小题1】How did the writer introduce the topic of the passage?A．By giving an example.B．By listing the facts.C．By telling a story.D．By giving a comparison.【小题2】What do we know about the Great Pacific Ocean Garbage Patch?A．It is made up of various kinds of plastic products.B．It is a solid mass of floating waste materials.C．It lies l60 000 kilometers east of California.D．It is described as a kind of oceanic land.【小题3】Why do people pay attention to the Great Pacific Ocean Garbage Patch?A．Because it may prevent the flow of ocean water.B．Because the polluted plastic products will affect the food chain.C．Because it maybe form an island in the pacific.D．Because ships may be trapped in the floating waste.

The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.

question or statement.Hot pot is a traditional dish in China. It is believed to date back more than 1,000 years to the time of the Jin Dynasty. Hot pot's origins can be found in the dining practices of Mongolian horsemen who rode across the steppe and into northern China. Legend has it that the Mongols used their helmets as pots to simmer (炖) broth (汤底) over open fires, and cooked chunks of meat in the broth.Hot pot cooking seems to have spread to northern China during the Tang Dynasty. In the regional variations developed with different ingredients such as seafood. In the centuries that witnessed the growth of the Song Dynasty, hot pot moved — and changed — further south, with each successive region adapting it to their local ingredients and tastes.The ingredients in a hot pot vary a lot from region to region. Perhaps the most famous hot pot is the Chongqing or Sichuan hot pot. It features a dark red broth chock-full (塞满了的) of spices, chili peppers, and the uniquely mouth-numbing Sichuan peppers. In Beijing and elsewhere in the north, hot pot broth tends to be mild and, compared to its racy southern "cousins", a little light. In the northeast of China, a kind of local sauerkraut (酸菜) is used to add some tang (强烈的味道), making the broth a bit sour. People can choose a version of hot pot according to their taste.1 Hot pot is believed to date back more than 1,000 years to the time of _______.A. the Jin Dynasty B. the Tang DynastyC. the Song Dynasty D. the Yuan Dynasty

The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.
