题目内容

While ________ in the countryside, he made many friends with the native there．

[　　]

A．worked

B．working

C．he works

D．he is working

答案：B
解析：

从结构上分析，while为连词，可以引导时间状语从句，C、D两项虽可以构成从句，但时态与主句不一致，若把A用于该空格，只能考虑为过去分词，而不是过去式，显然work的动作与主语he之间是主动关系，故应用现在分词形式表示主动，也可看作省去了he was的形式。

Sorry to say,our brains naturally start slowing down at the Cruelty young age of 30.It used to be thought that this couldn’t be helped,but new studies show that people of any age can train their brains to work faster.“Your brain is a learning machine,”saying University of California scientist Dr. Michael Merzenich.Given the right tools,we can train our brains to act like they did when we were younger.All that’s required is the practice designed just for the purpose:a few exercises for the mind.

Merzenich has developed a computer-based training method to speed up the process(过程) in which the brain deals with information (positscience.com).Since much of the data we receive comes through speech,the Brain Fitness Program works with language and hearing to better speed and accuracy(准确性).

Over the course of training,the program starts asking you to distinguish(辨别) sounds (between“dog”and“bog”,for example) at an increasingly faster speed.It’s a bit like tennis instructor,says Merzenich,hitting balls at you—faster and faster to keep you challenged(受到挑战).You may start out slow,but before long you’re pretty quick.

The biggest finding in brain research in the last ten years is that the brain at any age is highly plastic.If you ask your brain to learn,it will learn.And it may even speed up while in the process.

To keep your brain young and plastic you can do one of a million new activities that challenge and excite you:playing table tennis or bridge,doing crossword puzzles,learning a language...“When it comes to preventing ageing,you really do ‘use it or lose it’,”says Barbara Sahakian,professor at Cambridge University.

Dr.Merzenich’s training method mainly depends on ______.

A.speech training

B.computer languages

C.the activities one joins in

D.the information being dealt with

By saying “the brain at any age is highly plastic”,the writer probably means the brain can be ______.

A.used                                                            B.mastered

C.developed                                                     D.researched

What can we learn from the text?

A.Practice makes a quick mind.

B.Brain research started ten years ago.

C.Dr. Merzenich is a scientist in computer.

D.People believed nothing could stop the brain slowing down.

Which of the following agrees with the writer’s idea?

A.The training methods work better for the old.

B.People should use the brain to stop it from ageing.

C.The training of the brain should start at an early age.

D.It’s necessary to take part in as many activities as possible.

Recently, a study was carried out to determine who was the greatest American president．Sixty-five presidential historians took part in it, and they judged the past forty-two American leaders based on ten leadership qualities, including public persuasiveness (信服), crisis leadership, management of the economy, moral leadership, and conduct of international relations．The historians also looked at administrative (管理) ability, relations with Congress, ability to set goals, and the pursuit of equal justice for all．Finally, the experts took into consideration the historical period in which the president lived．

The historians chose Abraham Lincoln as American’s greatest president．He had also been named best president in a similar study in 2000．Abraham Lincoln was the president who led the nation through the Civil War in the 1860s, and was able to unite it in the end．He also took the first steps to abolish slavery in America．

Edna Medford, a professor of history at Howard University in Washington, D.C., was an adviser on this study and the earlier one．She says Abraham Lincoln is seen to represent the values the nation most honors, such as truthfulness, moderation, and respect for human rights．

The historians put American’s first president, George Washington, second on the list, while Franklin D．Roosevelt, Theodore Roosevelt, and Harry Truman follow in that order．John   F．Kennedy, the country’s first Roman Catholic president, is sixth on the list．Like Lincoln, Kennedy was murdered while in office．

Among recent presidents, Ronald Reagan was named the tenth best and Bill Clinton rated fifteenth, while the historians put former president George W．Bush at number thirty-six．His father, George H.W．Bush, did much better, being placed at number eighteen．

We learn from the text that ___________．

      A．this is the second time that Abraham Lincoln has been chosen as America’s greatest president

      B．Edna Medford didn’t take part in the study conducted in 2000．

      C．George H.W．Bush was thought to have done worse in office than George W．Bush

      D．Harry Truman was rated the fourth-best president by the study

Which of the following belong to the ten leadership qualities considered?

      a．Being able to persuade the public

      b．Taking effective measures during a financial crisis．

      c．Balancing home life and career．

      d．Pursuing equal justice for all．

   A．a,b,c             B．b,c,d        C．a,b,d        D．a,c,d

Who is rated worst among the following four presidents?

     A．John F．Kennedy                B．George Washington

     C．Bill Clinton                     D．George W．Bush

The text is mainly about ________．

     A．the ten qualities a great president needs

As more students begin to use computers for longer periods of time, more of them are suffering from eyestrain （视疲劳）．Just a few hours in front of a computer screen can make a person’s eyes feel tired and painful．A number of eye doctors have studied this growing problem and have found ways to deal with it．Following their advice will help keep computer users more comfortable．Here is some of the advice．
The light in a room shouldn’t be brighter than the computer screen itself．In many classrooms, however, the lights are far brighter than they should be．．Students can block some of this light by wearing baseball caps if they’re allowed at school．
A special computer screen should be used to cut down on bright light because it is especially tiring to the eyes．Another problem to avoid is the wrong kind of contrast．It is best to have dark letters on a light background．This causes less eyestrain than light letters on a dark background．
Students should be seated so that they are looking down at the computer screen rather than straight ahead, which is a far more tiring angle．The top of the monitor should be slightly lower than the top of the head．
The length of time students spend in front of a computer screen leads greatly to eyestrain．Students should take frequent breaks by looking away from the screen every fifteen or twenty minutes．During that time they should either close there eyes or focus on an object at a distance. Long – term computer use can dry out the eyes, so students should remember to blink frequently while in front of the screen.

China news, Beijing, Feb. 9 – Housing price in China has always aroused heated discussions among property developers（房产开发商）and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8,000 yuan per square meter, while in China, it is even higher than in the United States. This shows that there are some bubbles(泡沫) in Chinese real estate market, the International Finance News reported.

Although the average price of residential houses in the United States, after converted（转换）to Renminbi, is about 8,000 yuan per square meter, the houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. If US property developers sell their houses according to the building area, then the housing price will be even lower than 8,000 yuan per square meter. In most big Chinese cities, such as Beijing, Shanghai, and Shenzhen, houses are sold a t a price even higher than those in the US.

The high housing sales price in large cities in China proves that Chinese real estate（房地产）market does have some bubbles. Moreover, Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people’s average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in US?

At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate (控制) the real estate market by raising tax on property industry and controlling the release of loans（贷款）and lands to property developers. At the same time, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple means, it is expected that the high housing prices can be lowered.
