Between 2 and 3 pounds of wonder，it controls everything we say，do or think，who we are and what we care about. The way we walk or laugh or figure out things. What we like and the talents we possess. How we see and talk and run and jump and process our food.
The brain uses 20 percent of our body"s oxygen and 20 percent of its blood. Somewhere within its protein，fat, 100,000 miles of blood vessels and 100 billion nerve cells，it helps us remember where we put our gym shoes. Change our temperature so we don"t die because of the heat or cold. Speed us up or slow us down. Help us choose between orange juice or orangeflavored drinks.
Its intricacies(复杂性)are stunning，far beyond anything most of us can imagine. To keep this work of art as polished(有光泽的) as possible we need to eat right，exercise and keep mentally stimulated(刺激)．
Good nutrition helps brain cells communicate with each other. Exercise stimulates a hormone(荷尔蒙)in our brain that improves memory. Mental stimulation keeps you sharp even as you age.
“It"s very important that we tell people to be physically active and mentally active，” said neurologist Malcolm Stewart.
“People cannot stop aging，but you"re able to reduce the damage；you"re able to keep the function up.”
Following are Dr.Stewart"s advice for improving brain health：
| Nutrition | Avoid fast food. Follow the old adage(格言，谚语)：For breakfast，eat like a king；for lunch，like a queen；for supper，like a beggar. |
| Exercise | Do a combination of stretching aerobic and musclestrengthening every day. |

I tried to mind my manners and 45 listen, but usually I am too busy thinking about my day. On this day, 46 , her conversation was worth listening to.
“My father’s sick,” she said to no one in particular (专门) , I could see the 47 and fear in her eyes. “What’s wrong with him?” I asked. With her eyes wet and her voice tight from 48 the tears, she answered, “Heart trouble.” Her eyes 49 as she continued. “I have already lost my mum, so I don’t think I can stand losing him.”
I was 50 . My heart ached for her. And this reminded me of the great 51 that my own mother was thrown into when her father died. I saw how hard it was, and 52 is, for her. I wouldn’t like anyone to 53 that.

Not all children communicate well with their fathers．Communication is often left to mothers, while fathers dispense advice as and when necessary．Don’t expect all conversations to centre around the dinner table．Go to your children’s bedrooms and talk to them about school, their teachers or their friends．Remember that the conversation cannot be one-sided．When your children open up to you, you also need to open up to them．
If your children come home from school feeling upset, go up to them and ask them what is the matter．And if it is something which seems to you to be a silly reason to be upset, don’t voice your opinion．It may be silly to you, but to your children it is important enough．S

Al Herpin was 90 years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day, they never saw Herpin sleeping. In fact, he did not even own a bed. He never needed one.
The only rest that Herpin sometimes got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by his strange continuous sleeplessness. They asked him a lot of questions, hoping to find an answer. They found only one answer that might explain this question. Herpin remembered some talk about his mother having been injured several days before he was born. But that was all. Was this the real reason? No one could be sure.
Herpin died at the age of 94.

Although the long, cold winter has already started in South Korea, the annual (一年一度的) national exams have made the atmosphere very heated.
More than 675,000 South Korean high school graduates took the college entrance exam last Wednesday. They usually take exams in Korean, maths, sociology (社会学), history and foreign languages.
Officially there is one college place for every 1.33 students. But because all the students want to go to the top universities in the country, the competition can reach one place for 10 students. The students want to attend these colleges for both their famous names and better job opportunities.
Because students face fierce competition, they have to study very hard to realize their dreams. Park Seung said he and his classmates often go to school before 7:30 a.m. After school has finished at 6:30 p.m., most of them go to the library to continue their study instead of returning home. Since many libraries in South Korea are open 24 hours a day, they often stay long into the night. Many of the Senior 3 students only sleep for three to four hours a day. “I feel a lot of pressure, but I have to study very hard in order to make my dream come true. This is my lifetime goal and it will be a turning point in my life which could decide my future,” Park said.
The exam day is a very serious day for the whole of South Korea. Vehicles are not allowed within a 200-metre radius (范围) of all the test sites to make sure the students have quiet surroundings. Tooting (吹奏) of horns is forbidden, even airplanes are ordered to avoid landing and take-off near the test sites during listening comprehension test hours.
Students are told their scores in December before they apply for college. This is followed by face-to-face oral tests. There are public and private universities in South Korea. Many private universities are well-known, but their fees can be 18, 000 yuan each term. This has made a lot of students think again.
小题1:What do we know about South Korean annual national exams?
| A．Senior 3 students have to compete fiercely because there is only one place for 10 students. |
| B．Senior 3 students have to stay long into night at school. |
| C．Many of the Senior 3 students can’t have enough sleep. |
| D．Airplanes are ordered to avoid landing and take-off during national exams. |
| A．675, 000 | B．507, 520 | C．500, 000 | D．600, 000 |
| A．they can succeed more easily in future | B．they can learn more |
| C．they can make more money | D．it is interesting to study there |
| A．they will be interviewed | B．they will ask questions of colleges |
| C．they will not be tested any more | D．first they will pay all the education fee at all |
Over two million people have joined the Search for Extraterrestrial Intelligence（SETI）project. Based in California, the SETI project analyzes information taken from a giant radio telescope based in South America. Its task is to look for signals from outer space that might prove that life exists on other planets.
Processing this information is far too big a job for one computer. So the SETI project workers divide the work among volunteers who visit their website. Each computer gets some information to work out from the SETI network through the Internet. This process is often known as “meta-computing”.
It is a wonderful thought. You are sleeping, eating a meal or going out with friends. All this time, your computer is searching the stars for signs that might show something is out there trying to get in touch. Volunteers are proud of being involved in the SETI project. It shows that they understand the potential (潜能) of computing. They know that it is more than just a way of working or playing games.
Meta-computing may also be creating intelligence as well as looking for it. This idea is based on the theory that human intelligence is created by the way in which different parts of the brain communicate with each other. As the saying goes, “The whole is more than the sum of its parts.” People who join the SETI project sometimes wonder whether their computer will become part of a huge network that has learned to think for itself.
小题1:According to the writer, meta-computing may be creating intelligence .
| A．because human beings are intelligent | B．because a computer works as the brain does |
| C．because of a network of many computers | D．because of the number of computers |
| A．Radio telescope→SETI website→Volunteers’ computer→SETI base |
| B．Radio telescope→SETI base→SETI website→Volunteers’ computer |
| C．SETI base→SETI website→Volunteers’ computers→Radio telescope |
| D．SETI base→Radio telescope→SETI website→Volunteers’ computers |
| A．extra-terrestrial intelligence | B．human intelligence |
| C．the SETI project | D．meta-computing |
| A．a new way to work on the computer |
| B．a new way to work and play games |
| C．a new way to search for life outside the earth |
| D．a new way to make computers learn to think for itself |
