Be at your best!
What does your brain need to work well? Here are some things it needs.
Good food
Experts say that breakfast is much more important than any other meal. 1.. So don’t miss breakfast — especially before an exam! But you need to eat a good breakfast — junk food won’t work.
A regular supply of energy
Your brain needs a regular supply of energy, so you need to eat carbohydrates. They’re found in bread, rice, pasta and beans. 2.. They work more quickly than bread and rice, so they give you a short burst (爆发) of energy, but afterwards you feel more tired.
A continuous supply of oxygen (氧气)
Your brain needs oxygen, which it gets from exercise. 3.. You also need a good supply of iron because iron helps your blood to carry oxygen round your body.
Water
4.. Not getting enough water will stop your brain from working well. And remember, water isn’t as expensive as sweet drinks!
5.
Your brain needs several hours’ sleep, so it can ‘update’ itself, just like a computer. Experts say that when you study for a test or an exam, you should get some sleep as quickly as possible after you’ve finished studying. This helps you to remember what you’ve learnt.
A. A short break
B. A good night’s sleep
C. It works best in the morning
D. Exercise improves your memory too
E. Water is much better than sweet drinks
F. Your brain works better when you have eaten
G. Chocolate, biscuits and sweets are not good for your brain
Back in April 1939 and armed with $5,000 provided by the Rockefeller Foundation, Columbia University Teachers College professor Frank Cyr took a tour of ten states to make a research about school transportation problems. What he found was that many students had no dependable way to get to school and the ones who did often traveled in unsafe buses in the over 100,000 school areas.
Seeing a need to fix this problem, Cyr organized a meeting- one that would change the future of school buses forever. School officials and transportation experts met to set much-needed standards for buses, including those for color, height and width as well as safety rules that hadn’t been set before or that were different in every state.
There were many different bus colors in the US before this meeting; several areas even planned to have red, white and blue buses as a way of encouraging students to love their country. Cyr presented his new choices to education officials, a reported “50 shades(色度) changing from lemon yellow to deep orange-red”. The matter was settled quickly. Yellow, or “National School Bus Glossy Yellow”, was chosen because it was quite striking, making the school bus easy to be seen. Besides, it made the bold(黑体的), black writing on the side of each bus clear. (The bold, black writing gives information about each school area, telling students which school bus they could take during early morning and late afternoon hours.) Thirty-five states made the changes quickly, and every state was on board by 1974.
Being recognized as the “father of the yellow school bus”, Frank Cyr has surely influenced your life if you ever rode a school bus or saw that noticeable color pulling up to your stop on a dusky morning.

When we are young we are taught that it’s wrong to lie and we should always tell the truth. Unfortunately, most children lie even if they’re told not to. Research carried out at the Institute of Child Study at Toronto Univercity has shown that this might not be such a bad thing. Apparently (显然地), children who tell lies when they’re two years old have a good chance of becoming successful adults (成年人).
According to the research, at the age of two, 20 per cent of children lie. At the age of three, 50 per cent lie, and at four almost 90 per cent lie. By the age of 12 almost every child tells lies.
Lying needs much brain work, and the better the lie is, the more work the brain has to do. By training the brain early, researchers believe children will be able to think more clearly when they are adults.
Recent research, carried out by the Science Museum in London, has shown some interesting facts about the way we lie as adults. According to the research, the average British man tells three lies every day; that’s over 1,000 lies a year. However, the average woman apparently only lies twice a day.
Most people think women are better liars (说谎者) than men although in fact they tell fewer lies. Popular women’s lies include ‘Nothing’s wrong, I’m fine’, ‘I don’t know where it is, I haven’t touched it’, and ‘It wasn’t that expensive’.
Some people say you can lie as long as it’s a white lie. A white lie is a lie told to avoid hurting someone’s feelings. One of the most common lies for both men and women is ‘It’s just what I’ve always wanted’, said after opening a present from their partner.
1.What will happen to young children who lie?

3.What did the research by the Science Museum find out?
A.Men lie more than women. B.Women are better liars than men.
C.Women’s lies are usually not serious. D.Men sometimes have to lie to women.
4.What’s the true feeling behind the underlined part in the last paragraph?
A.You know me so well. B.I don’t like the present.
C.You are good at picking presents. D.I haven’t received a present I really like.
In the summer of 1885, nine-year-old Joseph Meister was very ill. He had been wounded by a sick dog that had rabies(狂犬病), a very dangerous disease. His parents were told that there was probably only one man who could save Joseph’s life——Louis Pasteur.
When Pasteur was a young boy in France, he spent many hours every day with the chemist (药剂师) who lived in his small town. At that time, the chemist had to make all the medicines himself. Young Louis enjoyed watching the chemist as he worked and helped those people who came to him each day.
As a school boy, Pasteur worked slowly and carefully. At first, his teachers thought that young Louis might be a slow learner. Through elementary school, high school, and college, Pasteur worked in the same thoughtful way. Then he became a college professor and a scientist , and he continued to work very carefully.
Pasteur was studying about the germs(细菌)that cause rabies when Joseph Meister became ill.In fact, Pasteur believed he had a medical treatment for rabies, but he had never given it to a person before. At first, Pasteur was afraid to treat Joseph, but the poor child was dying. Pasteur gave Joseph an inoculation(预防接种)every day for ten days. Slowly, the child became better.
During his lifetime, Pasteur studied germs and learned how they cause diseases in animals and people. He developed vaccinations(疫苗)that prevent many of these diseases. On September 28,1895, Louis Pasteur passed away, at the age of 72. The work of this great man has been of great help to modern medicine.

Kenya’s long-distance runners are among the best in the world. Is their food and daily routine (常规) a key to the secret of their success? We spent a week at a training camp with ten top athletes (运动员) to find out. This is what we discovered.
They eat five times a day:
08:00 Breakfast
10:00 Mid-morning snack
13:00 Lunch
16:00 Afternoon snack
19:00 Supper
The Kenyan runners’ food is based on bread, rice, potatoes, porridge, cabbage, beans and ugali (balls of cornmeal). Ugali is usually eaten with vegetables.
Meat is eaten in fairly small amounts, just four times a week. The athletes drink a lot of tea with milk and sugar. They get all the vitamins (维生素) they need from their food — they never take vitamin pills.
They usually train as a group twice a day. The first run is at 6 o’clock in the morning and the afternoon run is at 5 o’clock. They run 10 to 15 kilometres in the morning and 6 to 8 kilometres in the afternoon. Once a week, the two 1,500-metre runners in the group run shorter distances at higher speeds.
An amazing part of the Kenyan food is its richness in carbohydrates (碳水化合物). Every 24 hours, they have about 600 grams of carbohydrates to give them energy for their training. They only eat a little fat, most of it coming from the milk they have in their tea. They drink about a litre (升) of water every day. Surprisingly, they drink more than a litre of tea every day, too. They always eat soon after training.
Rest and sleep are also an important part of the athletes’ programme. They are always in bed early and they always get a good night’s sleep.
1.Why did the author go to the training camp?
A.To improve his running. B.To report who are the best runners.
C.To learn from the athletes’ good habits. D.To find out why the athletes do so well.
2.What do we know about the first group run of the day?
A.It starts at midmorning. B.It happens before breakfast.
C.It is shorter than the second run. D.It is led by two 1,500-metre runners.
3.What surprised the author about the athletes?
A.They drink a lot of tea. B.They eat five times a day.
C.They never take vitamin pills. D.They take in a lot of milk and sugar.
