1、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.By the end of summer 2007 the ice cover in the Arctic was ______【单选题】

A.38 million square kilometers

B.4.2 million square kilometers

C.1.13 million square kilometers

D.11.4 million square kilometers

正确答案:B

答案解析:本题难度不大，答案依据比较明显，文章第四段第二句谈到了，到2007年夏季结束时，冰层缩减至仅覆盖420万平方公里，所以答案是B。

2、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, ａｎｄ　the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds ａｎｄ　storm surges(风暴潮). The storm surges ａｎｄ　heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, ｏｒthe Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia ａｎｄ　in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding ａｎｄ　huge waves crashing on to the shore. During a hurricane, homes, businesses ａｎｄ　public buildings may be damaged ｏｒdestroyed, roads ａｎｄ　bridges can be washed away. A powerful hurricane can kill more people ａｎｄ　destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives ａｎｄ　not be able to get to a safe harbｏｒif they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm ａｎｄ　find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane ａｎｄ　go to a safer place near the center of your home. Cover yourself with a blanket ａｎｄ　be sure to keep away from windows ａｎｄ　glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.Paragraph 4 ______【单选题】

A.Where do hurricanes usually happen?

B.What damages can a hurricane cause?

C.What should you do during a hurricane?

D.What is a hurricane?

E.What are different names of hurricanes?

F.How do you know a hurricane is coming?

正确答案:C

答案解析:本题难度不大，段落主旨句比较明显，在文章第四段的第一句：If a hurricane is coming in your area, the most important thing is to stay calm ａｎｄ　find shelter immediately.回来看选项，C项简单概括了第一段的主要意思，是答案。

3、A Bad IdeaThink you can walk, drive, take phone calls, e - mail ａｎｄ　listen to music at the same time 7 Well, New York\'s new law says you can\'t. _____. The law went into force last month, following research ａｎｄ　a shocking number of accidents that involved people using electronic gadgets (小巧机械) when crossing the street.Who\'s to blame? Scientists say that our multitasking (多任务处理) abilities are limited. "We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist (神经科学家) in Tennessee. "But a core limitation is the inability to concentrate on two things at once."The young people are often considered the great multitaskers. However, an Oxford University research suggests this perception is open to question. Aｇｒｏｕｐof 18 to 21 years old ａｎｄ　aｇｒｏｕｐof 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. The youngerｇｒｏｕｐdid 10 percent better when not interrupted. But when both groups were interrupted by a phone call ｏｒan instant message, the olderｇｒｏｕｐmatched the youngerｇｒｏｕｐin speed ａｎｄ　accuracy.It is difficult to measure the productivity lost by multitaskers. Jonathan Spira, chief analyst at Basex, a business - research firm, estimates that the cost of interruptions to the American economy is nearly $ 650 billion a year. The estimate is based on surveys with office workers. The surveys conclude that 28 percent of the workers\' time was spent on interruptions ａｎｄ　recovery time before they returned to their main tasks.【单选题】

A.Talking on a cell phone while driving brings you joy anyway.

B.The estimate is based on surveys with office workers.

C.The youngerｇｒｏｕｐdid 10 percent better when not interrupted.

D.However, an Oxford University research suggests this perception is open to question.

E.Scientists say that our multitasking (多任务处理) abilities are limited.

F.ａｎｄ　you\'ll be fined $ 100 if you do so on a New York city street.

正确答案:F

答案解析:本题难度不是很大。可用排除法和代入法。本题的上文谈到纽约新的法律规定在走路开车时不能打电话，发邮件，听音乐，下文转到谈新法律发生效力时间，所以可以推断此处会继续跟着上文展开阐述，应该讲如果你做了会导致什么结果，回来看选项，把F代入文中，符合逻辑，答案是F。

5、Meet Your Memory1. Memory is something that cannot be seen, touched ｏｒweighed. It is thought to be abstract. It is a ｓｅｔof skills rather than an object. Neither is there a single standard fｏｒjudging a good ｏｒpoｏｒmemory. There are a number of different ways in which a person may have a good memory.2. Memory is generally viewed as consisting of three stages: (1) acquisition refers to learning the material; (2) storage refers to keeping the material in the brain until it is needed; (3) retrieval (提取) refers to getting the material back out when it is needed:3. Memory consists of at least two different processes: short - term memory ａｎｄ　long - term memory. Short - term memory has a limited capacity ａｎｄ　a rapid forgetting rate. Its capacity can be increased by chunking (组成大块), ｏｒgrouping separate bits of information into larger chunks. Long - term memory has an almost unlimited capacity.4. One measure of memory is recall, which requires you to produce information by searching the memory fｏｒit. In aided recall, you are given cues (提示) to help you produce the information. In free - recall learning you recall the material in any order. In serial learning you recall it in the ｏｒｃｅｒit was presented ａｎｄ　in paired - associate learning you learn pairs of words so that when the first word is given you can recall the second word. A second measure of memory is recognition, in which you do not have to produce the information from memory, but must be able to identify it when it is presented to you. In a third measure of memory, relearning, the difference between how long it took to learn the material the first time ａｎｄ　how long it takes to learn it again indicates how much you remember. Relearning is generally a more sensitive measure of memory than is recognition because relearning shows retention (保持) while recognition does not. Recognition is generally a more sensitive measure than recall.Grouping bits of information into larger chunks helps improve the capacity of our ______.【单选题】

A.short - term memory

B.relearning

C.needed

D.coded

E.recognition

F.slow forgetting rate

正确答案:A

答案解析:本题难度不大，答案依据比较明显，主要在第三段第三句：Its capacity can be increased by chunking…其中，Its capacity指的就是short - term memory的容量，回来看选项，A项short - term memory符合原文句意，是答案。
