Years ago, I owned the very best dog in the world. I was a child when we got her. She grew up with me, and was always there when I needed her. She died during one of my college vacations. My heart broke then, and I knew that there would never be another dog like her.

However, I was wrong. My next dog came into my life when I was married. My husband traveled for a living, and I was often lonely. This dog taught me to be patient. He always stayed at my side until the children were born, and then he became their guardian (±£»¤Õß), too. When he passed away, my heart broke. I was sure I would never love another dog as much as I loved him.

I was wrong again. We got the next one when the children were little. When he played with the children, he made them laugh. These days he spends more time with me since the children aren¡¯t around so much. He is, of course, the very best dog in the world.

I wonder if that¡¯s part of the lessen: to teach us that love has a spirit that returns again and again and never really dies.

It¡¯s amazing. They make room for one another. And they fit into our families, our lives, and our hearts, because they always have been and will be the best dogs in the world.

Opened in 1883, the Brooklyn Bridge was the first long?span bridge to carry motor traffic, and it quickly became the model for the great suspension bridges of the following century. Spanning New York's East River, it provided the first traffic artery £¨ÒªµÀ£©between Manhattan Island and Brooklyn. Before that, the only transportation was by ferries, which were slow and could be dangerous in winter.

The construction of a bridge over the EastRiver had been discussed since the early 19th century, but the outbreak of the Civil War in 1861 deflected all consideration of the project. When the war ended in 1865, the bridge became an important issue once more. In 1867, the New York State passed an act setting up the New York Bridge Company for the purpose of constructing a bridge between Manhattan Island and Brooklyn.

John Augustus Roebling was chosen to design the bridge. Born in Germany in 1806, he held aggressive views as a student and was listed by the German police as a dangerous figure. He emigrated to America in 1830 to escape political discrimination.

Roebling proposed a bridge with a span of 1,500 feet (465 m), with two towers in the East River serving as the main piers. The bridge that was actually built is longer¡ª1,597 feet (486 m), the longest suspension bridge at that time.

1.What was the purpose of building the Brooklyn Bridge?

A£®To replace an old bridge.

B£®To set up a model for bridge construction.

C£®To build a long?span bridge for the Civil War.

D£®To provide faster and safer transportation than boats.

2.Which of the following is closest in meaning to ¡°deflected¡± in the second paragraph?

A£®blocked B£®developed

C. deserved D£®indicated

3.Which of the following is TRUE about the Brooklyn Bridge?

A£®It was built in 1865.

B£®It is shorter than originally planned.

C£®It was first proposed after the Civil War.

D£®It was built by the New York Bridge Company.

4.According to the passage, which of the following correctly describes John Augustus Roebling?

A£®He participated in the Civil War and was seriously wounded.

B£®He was the first person to propose the construction of the bridge.

C£®He was chosen to design the bridge because of his aggressive views.

D£®He moved to America because he was discriminated against in his home country.

Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

__1.___ Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.

For years many doctors thought that repressing anger was more dangerous to a person¡¯s health than expressing it. They said that when a person is angry, the brain releases the same hormones (ºÉ¶ûÃÉ). They speed the heart rate, raise blood pressure, or sugar into the blood, etc. ___2.___

Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep anger inside may face a greater danger of high blood pressure.

__3.__ 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, ¡°___4.___ Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.¡±

Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. __5.__

A. In general the person feels excited and ready to act.

B. They said that laughter is much healthier than anger.

C. Expressing anger violently is more harmful than repressing it.

D. Anger may cause you a cancer.

E. Do not express your anger while angry.

F. Anger is a normal emotion that we all feel from time to time.

G. Doctors say the solution is learning how to deal with anger.

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (½çÃæ) (BCI) technology could help people with disabilities send commands to machines.

Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated£¨Õ¹Ê¾£©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 (¼¹Ëè) 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(ͷƤ) 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. Milan, 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¡úcomputer¡úcap¡úwheelchair

B. computer¡úcap¡úscalp¡úwheelchair

C. scalp¡úcap¡úcomputer¡úwheelchair

D. cap¡úcomputer¡úscalp¡úwheelchair

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

A. BCI Could Mean More Freedom for the Disabled

B. New Findings about How the Human Brain Works

C. Switzerland, the BCI Research Center

D. Robotic Vehicles Could Help to Cure Brain Injuries
