His first successful fight was for the equal rights of black people in South Africa. Then, as the first black president, he fought to unite the country and organize the government. Now Nelson Mandela has set his sights on a new enemy, AIDS.
On March 19 the 82-year-old, former president, hosted his second AIDS-awareness concert. He warned that 25 million people in Africa were already infected with the fatal disease.
Mandela was born in a small village in South Africa in 1918. He was adopted by the chief of his tribe and could have been a chief himself and lived a happy country life.
But he refused to be a chief when his people lived under racial discrimination(歧視). He decided to fight for equal rights for all the people in South Africa. Before 1990, under the country’s Racial Segregation Law, colored and white people lived separately. Black people were treated unfairly even when taking a bus. Blacks had to stand at the back of the bus to make room for white people even when there were only a few of them on board.
For his opposition to the system, Mandela was arrested and spent 27 years in prison. He was freed in 1990 and became the president of the country after the first election were held in which everyone could vote.
Mandela was not only a political fighter who attacked with speeches. He was also a trained boxer and fought in the ring when he was young.
“Although I did not enjoy the violence of boxing, I was interested in how one moved one’s body to protect oneself, how one used a strategy both to attack and retreat”, he wrote in his autobiography.
As a skillful fighter, he chose music as his weapon against AIDS. He hopes to win another victory against AIDS.

第二節(jié)讀寫(xiě)任務(wù)(共1小題，滿(mǎn)分25分)
閱讀下面的短文，然后按照要求寫(xiě)一篇150詞左右的英語(yǔ)短文。
Doctors say anger can be an extremely harmful emotion, unless you learn how to deal with it. They warn that angry feelings can lead to heart disease, stomach
problems, headaches, emotional problems and possibly cancer.
Anger is a normal emotion that we all feel from time to time. Some people
express anger openly in a calm, reasonable way. Others burst with anger, losing
control of themselves. But still other people control their anger. They cannot or will not express it.
Recently some doctors have found that people who express anger too often and
violently become, in fact, more and not less angry. This can cause medical problems.
Some doctors say that both controlling and expressing anger can be dangerous. They
believe that those who express anger strongly may be more likely to develop heart
disease, and they believe that those who deep their anger inside may face a greater
danger of high blood pressure.
Doctors say the solution is learning how to deal with anger. They say the first
step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, "Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably. "

Anger is a natural reaction which comes out when we feel that we have not been given a fair treatment. The positive side of this negative emotion is that it has helped us to evolve（逐步形成）as humans and cope in a better manner with our surroundings. However, it tends to become a problem when we fail to control it. Many a time it happens that your anger has hurt others or has spoiled one of your relationships for which you regret later. It has some bad effects on the health, too.
We should control anger so that it does not cause harm to us or to those around us whom we love. One of the best ways to control anger is to get help from others. If you feel that you are unable to manage your anger, it can make you more upset. So tell someone that is close to you, a friend or your father and mother, about your problem. When you discuss a matter with others, there is a better chance of finding a solution to your problem. Besides, there are no better stress relievers than humor. When you feel that it is because of stress that your anger is becoming unmanageable, you can use humor. It can help you look at difficult things in a lighter way and you will feel better about the things around you.
Anger tends to make us have a lot of negative thoughts. Therefore, we have to change the negative thoughts into positive ones. For this you have to first turn all the negative thoughts down that are in your mind one by one. This can be done with a lot of practice. Once you are successful in that, you have to maintain your focus only on the positive things of life.
Meditation (冥想) is an excellent anger management technique. In addition, what we do is disconnect ourselves from the outer world and focus all our attention into the inner world. This helps us develop a sense of controlling our thoughts that tend to cause anger.

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (BCI) technology could help people with disabilities send commands to machines.

Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated a small robotic wheelchair directed by a person's thoughts.

In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.

“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles.” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.

The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (頭皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.

Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”

He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

1.BCI is a technology that can ________.

A. help to update computer systems

B. link the human brain with computers

C. help the disabled to recover

D. control a person's thoughts

2.How did Tavella operate the wheelchair in the laboratory?

A. By controlling his muscles.

B. By talking to the machine.

C. By moving his hand.

D. By using his mind.

3.Which of the following shows the path of the signals described in Paragraph 5?

A. scalp→computer→cap→wheelchair

B. computer→cap→scalp→wheelchair

C. scalp→cap→computer→wheelchair

D. cap→computer→scalp→wheelchair

4.Which of the following would be the best title for the text?

A. Switzerland, the BCI Research Center

B. New Findings About How the Human Brain Works

C. BCI Could Mean More Freedom for the Disabled

D. Robotic Vehicles Could Help to Cure Brain Injuries

Most people think their time problems are outer, and that they are caused by the telephone, meetings, visitors, and delayed information or decisions. Although these problems often have a bad effete on them, as when people call or drop in, we usually contribute to them. We fail to have calls screened by a skillful secretary or assistant, or we leave our door open, actually assuring constant interruptions.

In almost all cases, it is possible to influence, if not control, it usually can cause problems, such as, slowness and indecision, lack of self-discipline, the inability to delegate, or the tendency to fight fires, to act without thinking, and to jump from task to task without finishing any of them.

Time is constant that cannot be changed. The clock cannot be slowed down or speeded up. Thus we cannot manage time itself. We can only manage our activities with respect to time.

The same skills are needed as those used in managing others—the abilities to plan, organize, delegate, direct, and control. Time management is simply self-management. It is impossible to be effective in any position without controlling one’s time effectively.

Successful time management does not mean working harder, but working smarter. All kinds of management skills must be used in the home and office to get most value from time.
