1、Meet Your MemoryMemory is something that cannot be seen, touched or weighed. It is thought to be abstract. It is a set of skills rather than an object. Neither is there a single standard for judging a good or poor memory. There are a number of different ways in which a person may have a "good" memory.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 blain until it is needed; and (3) retrieval (提取) refers to getting the material back out when it is needed.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), or grouping separate bits of information into larger chunks. Long-term memory has an almost unlimited capacity.One measure of memory is recall, which requires you to produce information by searching the memory for it. 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 order it 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:根据题干线索词Grouping bits of information into larger chunks定位原文至第三段第三句：Its capacity can be increased by chunking (组成大块), or grouping separate bits of information into larger chunks，句中的its即指前句中的short-term memory，题干将该句由被动语态转变为主动语态。由此推知，句中画线部分即为所需添加成分，即short-term memory，A选项short-term memory属于原文复现，故A为正确答案。

2、Man cannot exit without water. 【单选题】

A.expand

B.rise

C.live

D.quit

正确答案:C

答案解析:exist:存在，和live（生活、活着）意思相近；expand:拓展；rise:升起；quit:退出、放弃。

3、Houses of the FutureWhat will houses be like in thirty years\' time? No one really knows, but architects are trying to predict. _____Future houses will have to be flexible. In thirty years\' time even more of us will be working from home. So we will have to be able to use areas of the house for work for part of the day and for living for the rest. Families grow and change with children arriving, growing up and leaving home. The house of the future will have to grow and change with the family. Nothing will be as fixed as it is now. The house will always be changing to meet changing needs.Everyone agrees that in thirty years\' time we will be living in "intelligent" houses. We will be able to talk to our kitchen machines and discuss with them what to do. Like this, "We\'ll be having a party this weekend. What food shall we cook?" And the machine will tell us what food we will have to buy and how to cook it. We will be able to leave most of the cooking to the machines, just tasting things from time to time to check.The house of the future will be personal, each house will be different. You will be able to change the color of the wall easily.You won\'t have to paint them-you\'ll be able to tell the wall to change the color! And if you don\'t like the color the next day, you will be able to have a new one. The only thing you won\'t be able to do is move the house somewhere else!【单选题】

A.You will be able to change the color of the wall easily.

B.The only thing you won\'t be able to do is move the house somewhere else!

C.And the machine will tell us what food we will have to buy and how to cook it.

D.What will our home be like then?

E.The house of the future will have to grow and change with the family.

F.The kids might take their bedrooms with them as they leave.

正确答案:D

答案解析:本题的难度较大。需要认真阅读文章，特别是第一段和第二段，可用排除法和代入法。本题的上文谈到了没有人会知道30年后房子是什么样子，但建筑家们正在努力地预测。开头第一句用的是疑问句，下文的第一句就谈到未来的房子要十分灵活，用的是陈述句，可以推测此处很可能继续对未来房屋进行发问来展开文章的叙述，回来看选项，可以先排除A，B，C，F项，把D，E代入文章里，可以发现，D更能符合上下文语境和逻辑，是最佳答案。

4、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 nor rain. "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, for example, 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 for expensive 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 people of the coral island nations are unable to do anything substantial about the problem of global warming.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:题干大意：珊瑚岛国家的人对全球变暖问题无能为力。文章没有提到任何有关珊瑚岛国家的人的看法，故答案选C。

5、Stress Lessen CourseDoreen Sykora is now a junior at McGill University. She had a difficult time when she first began college. She said, "I was always well prepared for my examinations. But I would go in to class to take the exam, and I would fall apart. I could not answer the questions correctly-even though I knew the answers! I would just blank out because of nervousness and fear". Histoshi Sakamoto, an anthropology student at Temple University in Tokyo reports similar experiences. These two young students were experiencing something called test anxiety. Because when a student worries and is stressed about a test, his or her mind does not work as well as it usually does. The student cannot write or think clearly because of the severe tension and nervousness. Now there are special university courses to help students. In these courses, advisors and psychologists try to help students by teaching them to manage test anxiety. Such a course helps students learn to live with stress and not fail because of it. First students take a practice test to measure their worry level. If the tests show that their stress level is high, the students can take a short course to manage the fear. These courses teach students how to relax their bodies. They get training to become calm in very tense situations. By controlling their nervousness, they can let their minds work more easily. Learned information then comes out without difficulty on a test. Doreen Sykora saw immediate results after taking such a course. She now has enthusiasm about the relaxation methods. "Mostly, what I do is imagine myself in a very calm place. Then I imagine myself picking up a pencil. I move slowly and carefully. I breathe easily and let all the tension out. With each breath, more worry leaves me. It really works too. My grades have improved greatly! I\'m really doing well at McGill now. This relaxation method works not only on examinations, but it has improved the rest of my life as well". For Histoshi in Tokyo, the results were much the same. He is enjoying school a lot more and learning more. What\'s the meaning of "blank out" in Paragraph one?【单选题】

A.To be like a blanket.

B.To be sure of an answer.

C.To be relaxed.

D.To be unable to think clearly.

正确答案:D

答案解析:根据前后句，即使知道答案也不能正确回答问题，由于紧张和恐惧就会blank out，因此它的意思一定是不能够清楚地思考。因此选D。
