【题目】Man still has a lot to learn about the most powerful and complex part of his body — the brain.

It may be surprising to learn that it isn’t age that makes you lose your memory. The reason could be that you have a "lazy" memory, not an old one. Like your body your memory improves with exercise. Once given plenty of exercise, the brain keeps its power. Before discussing how to improve the memory, let’s look at how the brain works. There are two sides to the brain, the left and the right. The right side deals with the senses (what we see, hear, feel and smell). It's the creative and imaginative side. The left side is concerned with logic. It analyzes information and puts it in order.

Some recent research suggests that we remember everything that happens to us. The problem most of us has is recalling events. Most forgetting takes place immediately after learning. An hour after learning something new, more than 50% has been forgotten. After a month, 80% has been forgotten, and so on.

This shows revision is very important. If you revise new material you have learnt, you remember much more. So it's of vital importance to revise newly learned material often, and have frequent breaks. We best remember what we learn at the beginning of a learning period and at the point where we stop. After the break, revise what was learned before the break and then continue learning the new material. These breaks should happen every 20 or 45 minutes.

Other experiments have shown the brain needs time to "digest" what has been learned. The time necessary for this is 5 to 10 minutes. After the break, the memory will have absorbed what it has just learned, and more will be remembered. During this period it is important to exercise the right side of the brain, because the left side is used during the learning period. Therefore you should relax. Listening to music, breathing in fresh air, and looking at a picture are all ways of using the other side of the brain. So when you are studying alone, make a plan which shows when to have breaks and to revise newly learned material immediately before you begin studying again. If you do in this way, your memory will improve.

【题目】The following is the story of a SARS patient named Wang and his fight with the disease.

【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

【1】_______________

Safety in the highway is not totally out of our hands. Here are four ways we can protect ourselves when we travel.

2__________ people in small cars are injured more often and more severely than people traveling in large cars. Factories of small cars are strengthening their products’ safety, which helps. But the mix of large cars and small cars on the road is the main reason of the problem.

Being thrown into glass and mental cars parts, or being thrown from the car can really hurt or even kill you.

3_______The safety belt’s main purpose is to pull you back if your car has a sudden crash with another vehicle or object, or if it rolls over. A belt can reduce the chance of deadly injury by 45% and the chance of serious injury by 50%.

Air bags are important. More than half of all new cars sold have air bags. Air bags provide protection in frontal crashes—the type of crash that kills the most drivers—when they are also wearing safety belts. Most people are demanding air bags in the cars they buy.4_______________ Effective as they are, they can’t take the place of safety belts.

Drunk driving crashes are less likely to happen if you don’t drink.5____________Many people have realised that drunk driving can lead to death and injury, prison time and other results. There are movements to strengthen penalties(处罚) for drinking and driving.

A. How to drive safely?

C. How to protect ourselves in the highway?

D. Air bags are not installed in all cars.

E. That’s why safety belts should be worn.

F. Drunk driving is the most serious problem.

G. But the protection provided by air bags is limited in side or rear crashes.

【题目】It was once common to regard Britain as a society with class distinction. Each class had unique characteristics.

In recent years, many writers have begun to speak of the ‘decline of class and ‘classless society in Britain. And in modern day consumer society everyone is considered to be middle class.

But pronouncing the death of class is too early. A recent wide-ranging study of pubic opinion found 90 percent of people still placing themselves in a particular class; 73 percent agreeed that class was still a vital part of British society.; and 52 percent thought there were still sharp class differences. Thus, class may not be culturally and politically obvious, yet it remains an imprtant part of British society. Britain seems to have a love of stratification.

One unchanging aspect of a British person’s class position is accent. The words a person speaks tell her or his class. A study of British accents during the 1970s found that a voice sounding like a BBC newsreader was viewed as the most attractive voice. Most people said this accent sounds ‘educated and ‘soft ’. The accents placed at the bottom in this study, on the other hand, were regional(地区的) city accents. These accents were seen as ‘common and ‘ugly ’. However, a similar study of British accents in the US turned these results upside down and placed some regional accents as the most attractive and BBC English as the least. This suggests that British attitudes towards accent have deep roots and are based on class prejudice.

In recent years, however, young upper midder-class people in London, have begun to adopt some regional accents, in order to hide their class origins. This is an indication of class becoming unnoticed. However, the 1995 pop song Common People puts forward the view that though a middle-class person may want to live like common people they can never appreciate the reality of a working class life.

【1】A recent study of pubic opinion shows that in modern Britain_________.

A. it is time to end class distinction

A. regional B. educated

C. prejudiced D. unattractive

【4】British attitudes towards accent_________.

A. have a long tradition

B. are based on regional status

C. are shared by the Americans

D. have changed in recent years

【5】What is the main idea of the passage?

A. The middle class is expanding.

B. A person’s accent reflects his class.

C. Class is a key part of British society.

D. Each class has unique characteristics.

【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely(绝对地) terrifying.1. However, most deaths result from fear, without a plan or understanding what is happening to the car in the water. By adopting a brace(支撑) position, acting decisively and getting out fast, you can save yourself from a sinking vehicle.Brace yourself for impact (撞击力). As soon as you're aware that you're going off th e road and into a body of water, adopt a brace position. The impact could set off the airbag system in your vehicle, so you should place both hands on the steering wheel(方向盘) in the "ten and two" position.Undo your seatbelt. 2. Release the children, starting with the oldest first. Forget the cell phone call. Your car isn't going to wait for you to make the call.3. Leave the door alone at this stage and concentrate on the window. A car's electrical system should work for up to three minutes in water, so try the method of opening it electronically first. Many people don't think about the window as an escape choice either because of fear or misinformation about doors and sinking.Break the window. If you aren't able to open the window, or it only opens halfway, you'll need to break it with an object or your foot. It may feel counter-intuitive (有悖常理的) to let water into the car. 4.Escape when the car has equalized. If it has reached the stage where the car has been filled with water and it has become balanced, you must move quickly and effectively to ensure your survival. 5. While there is still air in the car, take slow, deep breaths and focus on what you're doing.

A. Open the window as soon as you hit the water.

B. This is the first thing to do, yet it often gets forgotten.

C. Surviving a sinking car is not as difficult as you think.

D. In short, if you know what to do in the water, you will be safe.

E. It takes 60 to 120 seconds for a car to be filled with water usually.

F. Such accidents are particularly dangerous to the risk of drowning(淹死).

G. But the sooner the window is open, the sooner you can escape directly through it.
