Ellen Sims is an 18-year-old college student. She has an important history exam tomorrow morning. Ellen is going to study all night. She is not going to at all. Many college students, like Ellen, do this often. They think that in the morning, they will everything that they studied the night before. Ellen thinks that this is a good way to study, but many doctors . They say that sleep is very important for memory and brain development.

Scientists at Harvard Medical School in the USA studied sleep and memory. They studied 24 people. First, they asked the people to look at a picture and it. At night, they put the people in groups of 12. Group One went to sleep. Group Two did not. A few days later, scientists showed some to both groups. They asked the people to find the picture they before. The people in Group Two did not do so as those in Group One. It wasn’t for them to remember the picture. What happened? Scientists say that sleep our memory. After we learn something new, sleep helps us remember it. And when we don’t sleep, we can new things.

Scientists say that many teenagers, like Ellen, sleep too They go to school and work, too. They also time with their friends. They’re always and they think sleep isn’t important. But scientists say the brains of teenagers are still , and sleeping is a very important part of the development. When teens sleep less than six hours, they can’t think clearly. That is not very helpful for a student who is taking an exam.

When we travel from one country to another, we find people have quite different feelings about food. People often feel what they eat is normal, and what other people eat is strange or silly. In most part of Asia, for example, people like rice and meat. In England, people eat potatoes every day. In the Middle East, bread is the main part of every meal. Eating, like so many things we do, becomes a habit which is difficult to change. Americans like to drink a lot of orange juice and coffee. The English drink tea four or five times every day. Australians drink a great deal of beer, and the French drink wine every day.

The sort of meat people like to eat is also different from one country to another. Horse meat is thought to be delicious in France. In Hong Kong, some people enjoy eating snakes. New Zealanders eat sheep, but they never eat goat meat. The Japanese don’t like to eat sheep meat because of its smell, but they enjoy eating uncooked fish.

People everywhere enjoy eating what they have always eaten, and there is very little we can do to change our eating habits.
