36 Finally, diversifying our diet away from heat sensitive wheat, corn, rice and other crops could also help "We've seen profound changes in the last decades in what we eat largely as a result of international trade, and I think that trend toward more diversification will continue," Jarvis says. "Depending on a greater number of plant species creates a more vigorous and less risky food system—and one that provides a broader range of nutritional requirements."36. One consequence of climate change is that some people may not have adequate access to certain foods.37. People around the world are eating foods more similar than what they used to eat.38. A recent news report talked about scientific efforts to help crops survive droughts through genetic engineering.39. It is predicted that climate change will affect the availability and price of quality chocolate.40. People wonder if certain crops and foodstuff could disappear like some animal species due to climate change.41. Although farms in the US can move a bit northward, crop yields may decrease.42. One possible solution to the food security problem is diversification of diet.43. It remains unsettled whether the global food supply problem can be solved by creating heat-tolerant through genetic engineering.44. Poor people may have to give up eating certain foods because of their high prices.45. A number of existing farming technologies could be used to reduce the negative effect of climate change on food production.

No card ever came with it. Calls to the flower shop were not helpful at all. After some time I stopped trying to find out the sender's name and was just pleased with the beautiful flower, in soft pink paper.I couldn't stop imagining who the giver might be. Some of my happiest moments were spent daydreaming(幻想)about the sender. My mother encouraged these daydreams. She'd ask me if I had been especially kind to someone. Perhaps it was one of my classmates. Perhaps it was the old man who I once helped. As a girl, I had more fun imagining that it might be a boy that I had met.A month before my high school graduation(毕业), my father died.

The triathlon is a sport that has three parts—swimming, bicycling and running. It is not an easy sport, but a man named Joe Salter is very good at it. A few months ago, he finished a special triathlon—he juggled(抛起接住)three balls all the time during the triathlon. That is to say, he kept on throwing and catching three balls while he was swimming, riding a bicycle and running.31-year-old Joe is from Florida, the USA. He loves juggling and he started at the age of 8. Joe did well in juggling. Later, he got the idea to do a triathlon and juggle at the same time to make it more fun. Many juggling fans laughed at his idea and thought it was just a joke. But Joe didn't give up and he kept practising it. Because of his hard work, he made it at last.Talking about his triathlon, Joe said swimming was the hardest part. "It was difficult and complex(复杂的)," he said. "I basically only used my legs, so it took quite a lot of work. Also, swimming in open water made it a little harder. It was not like in a pool."(1)According to the writer, the common triathlon ______.A.is a difficult sportB.is more famous than the marathonC.includes the three parts and jugglingD.includes the marathon and swimming(2)Joe's triathlon was special because ______ during the triathlon.A.he picked up three ballsB.he played jugglingC.he carried his bicycle on his shoulderD.he threw away all his balls(3)Many juggling fans thought Joe's idea ______.A.could not be realizedB.should not be laughed atC.should be realized as soon as possibleD.could make triathlon more exciting(4)The underlined part "made it" in the 2nd paragraph probably means ______.A.forgot B.failed C.succeeded D.left(5)Swimming was the hardest part for Joe mainly because ______.A.he swam in open waterB.his swimming skills were badC.he was very tired when swimmingD.he almost could only swim with his legs请仔细阅读下题中关于五个人旅游情况的描述,从A-G中选择出与之相对应的旅游建议,其中有两项为多余选项。A.

Ricky Gervais’s new film, The Invention of Lying, is about a world where lying doesn’t exist, which means that everybody tells the truth, and everybody believes everything everybody else says. "I’ve always hated you," a man tells a work colleague. "He seems nice, if a bit fat," a woman says about her date. It’s all truth, all the time, at whatever the cost. Until one day, when Mark, a down-on-his-luck loser played by Gervais, discovers a thing called "lying" and what it can get him. Within days, Mark is rich. famous, and courting the girl of his dreams. And be cause nobody knows what "lying" is, he goes on, happily living what has become a complete and utter farce. It’s meant to be funny, but it’s also a more serious commentary on us all. As Americans, we like to think we value the truth. Time and time again, public-opinion polls show that honesty is among the top five characteristics we want in a leader, friend, or lover; the world is full of woeful stories about the tragic consequences of betrayal. At the same time, deception is all around us. We are lied to by government officials and public figures to a disturbing degree; many of our social relationships are based on little white lies we tell each other. We deceive our children, only to be deceived by them in return. And the average person, says psychologist Robert Feldman, the author of a new book on lying, tells at least three lies in the first 10 minutes of a conversation. "There’s always been a lot of lying," says Feldman, whose new book, The Liar in Your Life, came out this month. "But I do think we’re seeing a kind of cultural shift where we’re lying more, it’s easier to lie, and in some ways it’s almost more acceptable." As Paul Ekman. one of Feldman’s longtime lying colleagues and the inspiration behind the Fox TV series "Lie To Me," defines it, a liar is a person who "intends to mislead," "deliberately," without being asked to do so by the target of the lie. Which doesn’t mean that all lies are equally toxic: some are simply habitual ―"My pleasure! "―while others might be well-meaning while lies. But each. Feldman argues, is harmful, because of the standard it creates. And the more lies we tell, even if they’re little white lies, the more deceptive we and society become. We are a culture of liars, to put it bluntly, with deceit so deeply ingrained in our mind that we hardly even notice we’re engaging in it. Spam e-mail (垃垃圾邮件), deceptive advertising, the everyday pleasantries we don’t really mean―"It’s so great to meet you! ""I love that dress"― have. as Feldman puts it, become "a while noise we’ve learned to neglect." And Feldman also argues that cheating is more common today than ever. The Josephson Institute, a nonprofit focused on youth ethics, concluded in a 2008 survey of nearly 30,000 high school students that "cheating in school continues to be spreading, and it’s getting worse." In that survey, 64 percent of students said they’d cheated on a test during the past year, up from 60 percent in 2006. Another recent survey, by Junior Achievement, revealed that more than a third of teens believe lying, cheating, or copying can be necessary, to succeed, while a brand-new study, commissioned by the publishers of Feldman’s book, shows that 18-to 34-year-olds―those of us fully reared in this lying culture―deceive more frequently than the general population. Teaching us to lie is not the purpose of Feldman’s book. His subtitle, in fact, is "the way to truthful relationships." But if his book teaches us anything, it’s that we should sharpen our skills― and use them with abandon. Liars get what they want. They avoid punishment, and they win others’ affection. Liars make themselves sound smart and intelligent, they attain power over those of us who believe them, and they often use their lies to rise up in the professional world. Many liars have fun doing it. And many more take pride in getting away with it. As Feldman notes, there is an evolutionary basis for deception: in the wild, animals use deception to "play dead" when threatened. But in the modern world, the motives of our lying are more selfish. Research has linked socially successful people to those who are good liars. Students who succeed academically get picked for the best colleges, despite the fact that, as one recent Duke University study found, as many as 90 percent of high-schoolers admit to cheating. Even lying adolescents are more popular among their peers. And all it takes is a quick flip of the remote to see how our public figures fare when they get caught in a lie: Clinton keeps his wife and goes on to become a national hero. Fabricating author James Frey gets a million-dollar book deal. Eliot Spitzer’s wife stands by his side, while "Appalachian hiker" Mark Sanford still gets to keep his post. If everyone else is being rewarded for lying, don’t we need to lie, too, just to keep up But what’s funny is that even as we admit to being liars, study after study shows that most of us believe we can tell when others are lying to us. And while lying may be easy, spotting a liar is far from it. A nervous sweat or shifty eyes can certainly mean a person’s uncomfortable, but it doesn’t necessarily mean they’re lying. Gaze aversion, meanwhile, has more to do with shyness than actual deception. Even polygraph machines are unreliable. And according to one study, by researcher Bella DePaulo, we’re only able to differentiate a lie from truth only 47 percent of the time, less than if we guessed randomly. "Basically everything we’ve heard about catching a liar is wrong." says Feldman, who heads the College of Social and Behavioral Sciences at the Universily of Massachusetts. Amherst. Ekman, meanwhile, has spent decades studying micro-facial expressions of liars: the split-second eyebrow arch that shows surprise when a spouse asks who was on the phone; the furrowed nose that gives away a hint of disgust when a person says "1 love you." He’s trained everyone from the Secret Service to the TSA, and believes that with close study, ifs possible to identify those tiny emotions. The hard part. of course, is proving them. "A lot of times, it’s easier to believe," says Feldman. "II takes a lot of cognitive effort to think about whether someone is lying to us." Which means that more often than not, we’re like the poor dumb souls of The Invention of Lying, hanging on a liar’s every word, no matter how untruthful they may be.Junior Achievement has found that more than one third of the teenagers believe that ______. A．most teachers are trustworthyB．the issue of ethics is out-of-dateC．deceiving is essential for successD．personality is related to education

An outright ban on plastics could cause even more harm to the environment and lead to triple the amount of greenhouse gas emissions.That's the finding of experts from Herriot-Watt University in Edinburgh，who say that replacing plastic with alternate materials such as metal and glass won't help the environment.The team say this is because the manufacturing of these replacements could double global energy consumption.Resources required to process these replacement materials would lead to more energy consumption and more greenhouse gas.Campaigners have called for reductions or bans，with recent programs such as the BBC's Blue Planet highlighting the impact of plastics on the world's oceans. But the learn of forty academics said surrounding a reduction or ban are often shortsighted and not based on facts.The waste products produced when making metal and glass are all bad for the environment.The major environmental impact of glass and metal production is caused by atmospheric emissions from melting activities.The burning of natural gas or fuel oil and the decomposition of raw materials during the meting lead to the edition of CO.Professor David Blackall，who led the research，said that transportation of consumer goods in plastic packaging means fewer vehicles because plastic is lightweight.Therefore burning less fuel and greatly reducing greenhouse gas emissions. The academics draw expertise from engineering，science，economies and social science，said there needs to be a "circular economy" for plastic usage. "Almost everything we touch or interact with on a daily basis is made of or contains a plastic of some description， " said Professor David Bucknall，chairman in materials chemistry from the university's Institute of Chemical Sciences. "Banning or reducing their use would have a massive impact on the way we live. "So whilst some people may wish for plastics to be reduced or banned altogether，we need to ensure we are replacing them with materials that are better for the planet.In many cases there is no credible alternative to using a plastic so we need to move towards a "circular economy" for plastics，rather than the largely "make-use-dispose" model we currently adopt.（1）What might be the best title for the text？ ____ A.Plastics Can Cause More Harm to the EnvironmentB.We Need to Replace Plastic with Alternate Materials such as Metal and GlassC.We Need to Move Towards a "Circular Economy" for PlasticsD.Banning Plastic Won't Help the Environment（2）What can we learn about the program of BBC's Blue Planet？ ____ A.It stresses the importance of plastics on the world's oceans.B.It explains the effect of plastics on the world's oceans.C.It promotes reductions or bans of plastics.D.It opposes replacing plastics with materials that are better for the planet.（3）According to Professor David Bucknall，what seems to be the best solution？ ____ A.

With the American’s Midterm Elections over, and a new Commander-in-Chief about to step in, some Americans are a little nervous about the nation’s future. But others feel secure, knowing that the man they consider the most powerful person in the world isn’t going anywhere. Just who is this behind-the-scenes guy they think has more power than George W. Bush ever will He’s Alan Greenspan, a 74-year-old expert economist who heads the Federal Reserve, commonly known as the Fed. Unlike the president, who has to please the voters and compromise with Congress, Greenspan doesn’t have to answer to anyone. But that doesn’t mean his job is easy. Basically, Greenspan is in charge of keeping the nation’s economy stable. The economy is sort of like a balloon: blow in too much air, and it pops. But with too little air, it falls to the floor. Greenspan helps decide when to blow more air into the economy. In this case, the air in a balloon is. the amount of money in the economy. Greenspan can make the economy grow by increasing the money supply, or keep the economy from inflating too much by decreasing the money supply. His goal is for the economy to grow and contract gradually. Rapid changes can harm businesses and consumers. In a speech lately, Greenspan hinted the Fed was concerned the economy might be slowing down too fast. What Greenspan actually said was that the Fed should "remain alert to the possibility that greater caution and weakening asset values in financial markets could signal or precipitate(促成) an excessive softening in household and business spending. "But what investors heard was: "I may lower interest rates which will make it easier for the companies you are investing in to borrow money. That means they’ll expand and their stock will be worth more in the future." Within hours of Greenspan’s remarks, so many investors bought stocks that the Dow Jones and the NASDAQ rose by three percent and ten percent that day. The value of some companies went up by millions of dollars, just because investors had confidence in Greenspan’s words. But Greenspan doesn’t just work magic by talking. He was educated at New York University and Columbia and appointed to his job in 1987 by President Ronald Reagan. And he’s credited with steering the country through some difficult times since then, including a serious stock market crash just after he took the job. Another reason Greenspan has become almost a celebrity in America, is that more people are paying attention to the stock market than ever before. It used to be that only rich people and powerful corporations had the extra money to invest in stocks. But the U.S. economy has done so well in recent years, that more and more ordinary people are investing in stocks. He’s a native New Yorker. His first focus was music: He attended New York’s Julliard School and toured the country for a year in the early 1940s, playing in the Henry Jerome swing band(摇摆乐队). If nothing else, friends believe, this experience of US travel gave him the ability to connect dispassionate(不带感情的) economic theories with the individuals they affect. "The most outstanding thing about his is he knows the American economy…," says friend Herbert Stein, an economist. A swing into economics carried him straight into moderate Republican politics. He advised Richard Nixon in his 1968 campaign, and served briefly in the Bureau of the Budget. Seven years later, he returned to government service, replacing Mr. Stein as chair of the Council of Economic Advisers in the final days of Nixon presidency. He agreed only after being assured that Vice President Ford would keep him. In that role, he helped formulate the inflation―fighting blueprint of the 1970s that reduced inflation from 11 to 6.5 percent. Greenspan is also known for taking hot morning baths that last as long as an hour, with his inbox within reach. The practice began years ago to counter a bad back. That has not kept him off Washington’s tennis courts, where he is renowned competitor. "I found his intensity remarkable and his approach shot serious," says one of Greenspan’s partners. Married to NBC newswoman Andrea Mitchell, Greenspan is also famous for his syntax(句法), or rather, the way it conceals virtually anything that could be said to be an opinion. This is partly the result of the natural silence of Fed officials, who understand that markets hang on their every word. But it is also part of Greenspan’s personality. One friend remembers encountering him in an airport, after violent storms had almost shut down air traffic on the East Coast. Asked about the weather, the Fed chairman said hesitantly that is was "OK." "He couldn’t even bring himself to be conclusive about the weather!" says’ the friend. After years of very high growth, the American economy is starting to slow down. Recently, corporations have been making less money and people are starting to have a harder time finding jobs. Greenspan is hoping to ease the economy into a soft landing―to make the car come to a gentle stop instead of hitting a brick wall. If he succeeds, the country will avoid two possible problems: rising prices and high unemployment. At the Fed’s meeting, Greenspan and the other members decided that the economy was growing at an OK rate, but that there is a possibility of a serious slowdown. If they are worried that the whole economy is starting to sink, they could lower interest rates at the next meeting in an attempt to encourage people to borrow and spend. While there’s no way to know what they will decide, one thing is certain: the decisions that Greenspan and the Federal Reserve Board make will affect everyone who earns, borrows or spends money.Why did Greenspan answer the question about weather hesitantly A．Because he needed to see clearly what the weather was like.B．Because he has a habit of being careful with his words.C．Because he was thinking about something important.D．Because he didn’t know the person who asked him the question.
