1、DietPersons who are overweight should watch their diet carefully in ｏｒｃｅｒto lose pounds. The best way to do this is to start a weight control program. At first it is wise to talk with your doctor. He can advise you of the number of calories you should have in your meals each day. He can tell you about exercising while on your diet. A good rule is to lose slowly. A loss ofa pound ｏｒtwo is plenty. Plan meals around foods you know. This means that it is wise to include foods that you are used to ａｎｄ　that are part of your regular eating habits. When you have lost the weight you wish, simple items can be added to your diet so that you can maintain the weight you want. While you are dieting, try to build a pattern of eating that you can follow later to maintain your desired weight. When dieting, choose low-calorie foods. Avoid such items as fats, fried food, sweets, cakes, cream ａｎｄ　soft drinks. Try to take coffee ａｎｄ　tea without sugar ｏｒcream. Snacks can be part of your diet. Fｏｒexample, a piece of fruit ｏｒa simple dessert saved from mealtime can be eaten between meals. Keep busy! This way you will not be tempted to go off the diet. Make full use of opportunities to exercise. Try walking instead of riding whenever possible. Happy dieting !If you want to start a weight control program, you should ____. 【单选题】

2、Dung to DeathFields across Europe are contaminated with dangerous levels of the antibiotics given to farm animals. The drugs, which are in manure sprayed onto fields as fertilizers, could be getting into our food ａｎｄ　water, helping to create a new generation of antibiotic-resistant "superbugs". The warning comes from a researcher in Switzerlａｎｄ　who looked at levels of the drugs in farm slurry His findings are particularly shocking because Switzerlａｎｄ　is one of the few countries to have banned antibiotics as growth promoters in animal dead.Some 20,000 tons of antibiotics are used in the European ｕｎｉｏｎａｎｄ　the US each year. More than half are given to farm-animals to prevent disease ａｎｄ　promote growth. But recent research has found a direct link between the increased use of these farmyard drugs ａｎｄ　the appearance of antibiotic-resistant bugs that infect people. Most researchers assumed that humans become infected with the resistant strains by eating contaminated meat. But far more of the drugs end. up in manure than in meat products, says Stephen Mueller of the Swiss Federal Institute fｏｒEnvironmental Science ａｎｄ　Technology in Dubendorf. ａｎｄ　manure contains especiaily high levels of bugs that are resistant to antibiotics he says.With millions of tons of animals manure spread onto fields of crops such as wheat ａｎｄ　barley each year, this pathway seems an equally likely route fｏｒspreading resistance, he said. The drugs contaminate the crops, which are then eaten. ______Mueller is particularly concerned about aｇｒｏｕｐof antibiotics called sulphonamides. They do not easily degrade ｏｒdissolve in water. His analysis found that Swiss farm manure contains a high percentage of sulphonamides; each hectare of field could be contaminated with up to 1 kilogram of the drugs. This concentration is high enough to trigger the development of resistance among bacteria. But vets are not treating the issue seriously. There is growing concern at the extent to which drugs, including antibiotics, are polluting the environment. Many drugs given to humans are also excreted unchanged ａｎｄ　are not broken down by conventional sewage treatment.【单选题】

A.They do not easily degrade ｏｒdissolve in water.

B.ａｎｄ　manure contains especiaily high levels of bugs that are resistant to antibiotics he says.

C.Animal antibiotics is still an area to which insufficient attention has been paid

D.But recent research has found a direct link between the increased use of these farmyard drugs ａｎｄ　the appearance of antibiotic-resistant bugs that infect people.

E.His findings are particularly shocking because Switzerlａｎｄ　is one of the few countries to have banned antibiotics as growth promoters in animal dead.

F.They could also be leaching into tap water pumped from rocks beneath fertilized fields.

正确答案:F

答案解析:选项F中的also 一词说明前面应讲到过一个类似的内容。这句讲的是这些药物可能从施过肥料的农田下面的岩石沥滤到自来水里去；前面一句讲的是受到这些药物污染的谷物被人食用，这两句讲的都是这些药物如何对人类造成威胁。

3、Arctic MeltEarth\'s North ａｎｄ　South Poles are famous fｏｒbeing cold ａｎｄ　icy. Last year, however, the amount of ice in the Arctic Ocean (北冰群) fell to a record low.Normally, ice builds in Arctic waters around the North Pole each winter ａｎｄ　shrinks(缩小) during the summer. But fｏｒmany years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent ｄｒｅｐin end of summer ice cover. Between 1981 ａｎｄ　2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.Last summer, Arctic sea ice reached its thinnest levels. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. ａｎｄ　it\'s a very large 23 percent below the previous record low, which was ｓｅｔjust 2 years ago. This continuing trend has made scientists concerned to.There may be several reasons fｏｒthe ice melt, says Jinlun Zhang, an oceanographer (海洋学家)at the University of Washington in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice ａｎｄ　open water.Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water ａｎｄ　the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.57 Celsius warmer than the average ａｎｄ　1.5c warmer than the previous record.With both air ａｎｄ　water getting warmer, the ice is melting from both above ａｎｄ　below. In some parts of the Beaufort Sea, north of Alaska ａｎｄ　western Canada, ice that measured 3.3 meters thick at the beginning of the summer was measured just 50 cm by season\'s endThe new measurements suggest that melting is far more severe than the thinking of scientists. Some scientists fear that the Arctic is stuck in a warming trend.The Beaufort Sea mentioned in paragraph 7 is an example to show ______.【单选题】

A.how accurate the new measurements are

B.how thick the ice is in it

C.how serious the problem of the ice melt in the Arctic is

D.how dangerous it is to travel to it

正确答案:C

答案解析:本题难度不大，答案依据比较明显，文章第七段和第八段谈到，夏天冰层以超出科学家预料的速度迅速融化，答案是C。

4、Cell Phones1. Believe it ｏｒnot, cell phones have been around fｏｒover a quarter of a century. The first commercial cell phone system was developed by the Japanese in 1979, but cell phones have changed a lot since that time. The early cell phones were big ａｎｄ　heavy but they have developed into small ａｎｄ　light palm sized models. There are huge developments in their functions, too. We have had call forwarding, text messaging, answering services ａｎｄ　hands - free use fｏｒyears, but now there are new facilities, such as instant access to the Internet ａｎｄ　receiving ａｎｄ　sending photos.2. Cell phones have become very common in our lives. Recent statistics suggest one in three people on the planet now have cell phone, ａｎｄ　most of them say they couldn\'t live without one, Cell phones are used in every area of our lives ａｎｄ　have become a necessary tool, used fｏｒessential arrangements, social contact ａｎｄ　business. It easier to call fｏｒhelp on the highway. It possible to keep in touch with people "on the move" when people are traveling.3. Cell phones have made communication easier ａｎｄ　have reduced the need fｏｒfamily arguments f We can use cell phones to let our family know we\'ll be late ｏｒif there\'s a sudden change of plan ｏｒan emergency. Cell phones have eased the worries of millions of parents when their teenagers are out late. They can now contact their children at any time.4. This does not mean that cell phones are all good news. Cell phones have brought with them a number of new headaches fｏｒtheir owners. It costs a lot to replace stolen phones, It is becoming a frequent occurrence, ａｎｄ　have you ever seen such a huge phone bills? More serious, however, Cell phones bring the potential health problem. There are fears that radiation from the phones may cause brain tumｏｒ肿瘤). This may be a time bomb waiting to happen to younger people who have grown up with cell phones. They simply can\'t live without cell phones!Paragraph 5 ______【单选题】

A.Cell phones ａｎｄ　the family

B.Commercial cell phone systems

C.Cell phones in everyday life

D.Cell phones fｏｒteenagers

E.History of cell phones

F.Problems with cell phones

正确答案:F

答案解析:本题难度不大，主旨句比较明显，就是第四段的第一句：这并不意味着手机带来的都是好消息。后面谈到了手机带来的问题，F项Problems with cell phones是本段主旨句的近义解释，是答案。

5、The Threat to KiribatiThe people of Kiribati are afraid that one day in the not-too-distant future, their country will disappear from the face of the earth-literally. Several times this year, the Pacific islａｎｄ　nation has been flooded by a sudden high tide. These tides, which swept across the islａｎｄ　ａｎｄ　destroyed houses, came when there was neither wind nｏｒrain. "This never happened before," say the older citizens of Kiribati.What is causing these mysterious high tides? The answer may well be global warming. When fuels like oil ａｎｄ　coal are being burned, pollutants (污染物) are released. These pollutants trap heat in the earth\'s atmosphere. Warmer temperatures cause water to expａｎｄ　ａｎｄ　also create more water by melting glaciers (冰川) ａｎｄ　polar (极地的) ice caps.If the trend continues, scientists say, many countries will suffer, Bangladesh, fｏｒexample, might lose one-fifth of its land. The coral (珊瑚) islａｎｄ　nations of the Pacific, like Kiribati ａｎｄ　the Marshall Islands, however, would face an even worse fate-they would be swallowed by the sea. The loss of these coral islands would be everyone\'s loss. Coral formations are home to more species than any other place on earth.The people of these nations feel frustrated. The sea, on which their economies have always been based, is suddenly threatening their existence. They don\'t have the money fｏｒexpensive technological solutions like seawalls. ａｎｄ　they have no control over the pollutants, which are being released mainly by activities in large industrialized countries. All they can do is to hope that industrialized countries will take steps to reduce pollution.The heat released by burning oil ａｎｄ　coal is the direct cause of global warming.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:题干大意：燃烧石油和煤放出的热量是全球变暖的直接原因。文章第二段提到：When fuels like oil ａｎｄ　coal are being burned, pollutants (污染物) are released. These pollutants trap heat in the earth\'s atmosphere. 当燃料（如石油和煤）被燃烧，释放污染物，这些污染物圈住地球大气层中的热量。这是引起全球变暖的一个原因。而题干把它范围缩小，说成直接原因，故答案选B。
