该移动会造成南亚地区降水丰富，因为北移的东南信风越过赤道，受地球自转影响，风向右偏形成西南季风，西南季风掠过暖湿的印度洋洋面，带来丰沛的降水。

该移动会导致澳大利亚北部干旱少雨，因为该区在这一期间转为受干燥的东南信风控制，所以干旱少雨。

（十六）（本题16分）36．位于非洲大陆最南部，东、南临印度洋，西濒大西洋。

优：地处两大洋间的航运要冲，西南部的好望角航线是世界上最繁忙的海上通道之一。

（任答一点即可）劣：好望角的航线长，交通运输成本较高；好望角航线航线有风浪危险。

（任答一点即可）37.南非南部沿海有本格拉寒流和厄加勒斯暖流交汇，西部沿海出现甬升流，为西部、南部沿海带来大量营养物质，有利于浮游生物的生长，浮游生物又为鱼类提供了丰富的饵料，吸引大批鱼群。

38.甲地为地中海型农业；农作物以小麦、大麦等冬季谷物为主；规模相对较小；或以抗旱耐热的经济作物为主，如葡萄、油橄榄等（任答一点即可）。

39.分布特点：耕地主要分布在沿海和东北部地区，而西部地区耕地少。

原因：沿海平原地势低平，东北部高原地势平坦，且降水量大多在500毫米以上，适合耕作；而西部地区降水少，荒漠化严重，不适合耕作。

The latest __41__ on superfast broadband delivered by fiber to the home (FTTH) show 18% growth over the last survey compiled in late 2008.The continued growth suggests that the __42__ economic decline has not hit plans to build fiber networks.

Karel Helsen, president of Europe’s Fiber-To-The-Home Council, said the growth matched predictions that were __44__ when the credit crisis started to make itself felt. “The numbers in 2009 are in line with the latest forecasts,” said Mr. Helsen.By 2012, the FTTH Council expects that 13 million people across 35 European nations will have their broadband delivered by fiber.

So companies turn to public, inviting people to lend them money, or take a share in the business in __53__ for a share in future profits. This they do by __54__ stocks and shares in the business through the Stock Exchange. By doing so they can put into circulation the savings of __55__ and organizations, both at home and overseas. When the saver needs his money back, he does not have to go to the company with whom he originally placed it. __56__, he sells his shares through a stockbroker to some other saver who is seeking to __57__ his money.Many of the __58__ needed both by industry and by each of us are provided by the government or by local authorities.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)A voyaging ship was wrecked during a storm at sea and only two of the men aboard were able to swim to a small, desert-like island. Not knowing what else to do, the two survivors agreed that they had no alternativethan to pray to God.However, to find out whose prayers were more powerful, they agreed to divide the territory between them a nd stay on opposite sides of the island.The first thing they prayed for was food. The next morning, the first man saw a fruit-bearing tree on his side of the island, and he was able to eat its fruit. But the other man’s parcel of land remained barren.After a week, the first man became lonely and decided to pray for a wife. The next day, another ship was wrecked and the only survivor was a woman who swam to his side of the island. But on the other side of the island, there was nothing.Soon thereafter the first man prayed for a house, clothes and more food. The next day, like magic, all of these things were given to him. However, the second man still had nothing.Finally, the first man prayed for a ship so that he and his wife could leave the island, and in the morning he found a ship docked at his side of the island.The first man boarded the ship with his wife and decided to leave the second man on the island, considering the other man unworthy to receive God’s blessings since none of his prayers had be enanswered.As the ship was about to leave, the first man heard a voice from Heaven booming, “Why are you leaving your companion on the island?”“My blessings are mine alone since I was the one who prayed for them,” the first man answered. “His prayers were all unanswered and so he doesn’t deserve an ything.”“You are mistaken!” the voice rebuked him. “He had only one prayer, which I answered. If not for that, you would not have received any of my blessings.”“Tell me,” the first man asked the voice, “what did he pray for that I should owe him anything?”“He prayed that all your prayers would be answered.”For all we know, our blessings are not the fruits of our prayers alone, but those of another praying for us. So what you do for others is more important than what you do for yourself.65.

Later he met individually with Democratic and Republican House and Senate leaders and spoke to a bipartisan leadership gathering. In comments to reporters early on Monday, he emphasized the urgency of finalizing economic legislation (立法). “We have got an extraordinary econ omic challenge ahead of us,” he said, “Weare expecting a sobering job report at the end of the week. Nancy Pelosi and her staff have been extraordinarily helpful in working with our team so that we can shape an economic recovery and reinvestment plan that starts putting people back to work.”Mr. Obama wants tax cuts for individual Americans and businesses to make up a significant portion of expected legislation. This could involve as much as $300 billion of a bill that is likely to go beyond $700 billion and include aid to cash-poor U.S. states, and money for alternative energy and a range of infrastructure (基础设施) projects. Later, Mr. Obama said he expects to be able to sign legislation as soon as the end of this month, adding that quick action is necessary to “break the drive of the U.S. econo mic depression”.Emerging later from bipartisan talks with Mr. Obama, Nancy Pelosi said lawmakers discussed with the president how to pass a stimulus package as quickly as possible. “An economic recovery package that will create jobs immediately and will grow the economy and that is what we talked about today,” said Nancy Pelosi. “How we could do this fast, deliberatively and to act upon it soon.” Just how soon that would be, Pelosi would not say.How much support Democrats can obtain from Republicans will depend on the details. But the severity of the U.S. economic depression has created considerable bipartisan backing for quick action. Senate Majority Leader, Harry Reid said: “There are investments that we need to make on behalf of the American people to turn around this economy. We felt very good about the meeting; we ar e confident that we can do this and we have to do this.”“I think the best thing I can do is to decline to comment on what they are going to do going forward,” said Dana Perino. “Obviously, we think that tax cuts were the right way to help our economy get out of the economic depression that this president inherited and we know that tax cuts can stimulate innovation.” Asked by reporters how large the economic stimulus package might be, Senate Majority Leader Reid said Obama indicated that all but one of some 28 economists advising him had said it should range from $800 billion to $1.3 trillion.72.

There is one extra heading which you do not need.A. Factors that influence reactions to pollutantsB. Possible sources of indoor air pollutionC. Ways to identify diseases with similar symptomsD. Long-term effects after repeated exposureE. A commonly-ignored health threatF. Immediate symptoms and regular treatment76.Most people are aware that outdoor air pollution can damage their health, but many do not know that indoor air pollution can also have significant health effects. Environmental Protection Agency studies indicate that indoor levels of pollutants may be 2-5 times, and occasionally more than 100 times, higher than outdoor levels. These levels of indoor air pollutants may be of particular concern because most people spend about 90％of their time indoors.[来源:]77.There are many sources of indoor air pollution in any home. These include combustion sources such as oil, gas, coal, wood, and tobacco products; building materials and furnishings as diverse as deteriorated asbestos-containing insulation, wet or damp carpet, and cabinetry or furniture made of certain pressed wood products; products for household cleaning and maintenance, personal care, or hobbies; central heating and cooling systems and humidification devices; and outdoor sources such as radon, pesticides, and outdoor air pollution.78.Immediate effects may show up after a single exposure or repeated exposures. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Such immediate effects are usually short-term and treatable. Sometimes the treatment is simply eliminating the person's exposure to the source of the pollution, if it can be identified. Symptoms of some diseases, including asthma, hypersensitivity and fever, may also show up soon after exposure to some indoor air pollutants.[来源:]79.The likelihood of immediate reactions to indoor air pollutants depends on several factors. Age and pre-existing medical conditions are two important influences. In other cases, whether a person reacts to a pollutant depends on individual sensitivity, which varies tremendously from person to person. Some people can become sensitized to biological pollutants after repeated exposures, and it appears that some people can become sensitized to chemical pollutants as well.80.Certain immediate effects are similar to those from colds or other viral diseases, so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution. For this reason, it is important to pay attention to the time and place the symptoms occur. If the symptoms fade or go away when a person is away from the home and return when the person returns, an effort should be made to identify indoor air sources that may be possible causes.Section DDirections: Read the passage carefully. Then answer the questions or complete the statements inthe fewest possible words.Children and adolescents who watch a lot of television are more likely to have antisocial and criminal behavior when they become adults, according to a new University of Otago, New Zealand, study published online in the journal Pediatrics. The study followed a group of around 1,000 children born in the New Zealand city of Dunedin in 1972-1973. Every two years between the ages of 5 and 15, they were asked how much television they watched. Those who watched more television were more likely to have a criminal conviction and were also more likely to have antisocial personality traits in adulthood.The study found that the risk of having a criminal behavior by early adulthood increased by about 30% with every hour that children spent watching TV on an average weeknight.The study also found that watching more television in childhood was associated, in adulthood, with aggressive personality, an increased tendency to experience negative emotions, and an increased risk of antisocial personality disorder; a psychiatric disorder characterised by persistent patterns of aggressive and antisocial behavior.The researchers found that the relationship between TV viewing and antisocial behavior was not explained by socio-economic status, aggressive or antisocial behavior in early childhood, or parenting factors.A study co-author, Lindsay Robertson, says it is not that children who were already antisocial watched more television. “Rather, children who watched a lot of television were likely to go on to manifest antisocial behavior and personality traits.”Other studies have suggested a link between television viewing and antisocial behavior, though very few have been able to demonstrate a cause-and-effe ct sequence. This is the first ‘real-life’ study that has asked about TV viewing throughout the whole childhood period, and has looked at a range of antisocial outcomes in adulthood. As an observational study, it cannot prove that watching too much television caused the antisocial outcomes, but the findings are consistent with most of the research and provides further evidence that excessive television can have long-term consequences for behavior.Antisocial behavior is a major problem for society. While we’re not saying that television causes all antisocial behavior, our findings do suggest that reducing TV viewing could go some way towards reducing rates of antisocial behavior in society,” says Associate Professor Hancox.The American Academy of Pediatrics recommends that children should watch no more than 1 to 2 hours of quality television programming each day. The researchers say their findings support the idea that parents should try to limit their children's television use.(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)81.
