You may not have heard the words “freshman fifteen” before, but they are very important for students who are entering university. A freshman is a first-year college student. “Fifteen” refers to fifteen pounds—the fifteen pounds added to a student’s weight in his or her first year. There are a number of reasons why first-year university students gain (增力n) weight; but it’s encouraging to know that freshmen don’t have to add these harmful fifteen pounds.
Mistakes choosing food
University kitchens serve(供应）many kinds of food. Some students choose unhealthy food，because now their parents are not nearby to help them choose. Some students visit the kitchen many times while studying. Late at night, some students get harmful fast food such as fish and chips with Coke to drink. Students also have less time for walking, running, and doing sports because of their schoolwork.
If you，re careful, you don，t have to add fifteen pounds. Here are some ideas：
l Think more about what you eat.
l Eat plenty of vegetables and healthy meats.
l Don’t eat desserts full of sugar；have fruit after dinner.
l Try not to eat so much unhealthy food while you study.
l It，s all right to have a little fast food sometimes—but not often.
l Write down the foods you eat.
l Walk, run, do sports—move and you will feel better!
Remember that the “freshman fifteen” can happen to anyone. Talk to your friends about it. Together, try to eat healthy food and not to eat unhealthy food. Walking, running, and playing sports is always more fun with friends. Help each other and you can have a healthy and happy freshman year.

What would you do if you found a snake in your house? Many people might be afraid or try to kill it. However, if you live in North Carolina in the USA, one thing you can do is to call the Snake Catchers.
The Snake Catchers are four men who love snakes, even poisonous ones. Their newspaper advertisementsays, “Snake Catchers：free snake removal(除去）一Please do not kill them — Call us. ”
The Snake Catchers, who started their service in 1998, don’tcharge anything for helping people. “We do this as a hobby,” explained Fred Johnson, one of the Snake Catchers.
Because of their love of snakes, the Snake Catchers try to keep them alive. “One man asked us to kill a python(蟒蛇),so he could make a pair of boots from the skin. We refused, because we like snakes, and we don’t want to see them killed, ” said Fred.
Some of the snakes that they catch are kept as pets; some are given to the North Carolina State University. Most, including the poisonous snakes, are set free in the wild, usually in a national park.
Fred suggests that people should treat snakes with care. “Actually snakes are very shy and gentle creatures. They only attack if they are frightened. However, you have to know how to treat a snake properly!”
According to one happy family, the Snake Catchers are good. One day, the Greenwood family found a snake skin in the kitchen. They looked very carefully and saw a snake sleeping behind a cupboard. They thought about what to do. Then Steve Greenwood remembered the advertisement for the Snake Catchers. He called them.
“The Snake Catchers arrived within an hour and they finished the job quickly too,” said Steve Greenwood. “One of them went into the kitchen, found the snake and took it out alive. The Snake Catchers did a very good job.”
Last year, the Snake Catchers removed more than seventy snakes from houses in North Carolina.

In 1901, the citizens of Colorado Springs in the USA decided to collect everyday items and to seal (封住）them in a special box. The box was marked “To be opened after midnight, December 31st, AD 2000”，and was kept in the Colorado College Library.
One hundred years later, on the appointed(约定）day, 300 people gathered to watch the opening of the box. Many in the crowd were the descendants(后代）of people who had placed things inside the box.
When the box was opened after midnight, the things inside the box were in very good condition. There were newspapers, photos, diaries, name cards, family trees, books and lots of letters, includingone written by Theodore Roosevelt, who became the President of the USA later that year. One of Roosevelt’s friends lived in Colorado Springs at that time.
Many of the letters were written to their descendants. They describe the hopes that the people of 1901 had for the people of the next century. At that time, Colorado Springs had just a few thousand people. Now nearly half a million people live there.
Colorado College Library has scanned the materials and put them on a website. Cecil Muller, whose grandfather had placed a collection of postcards in the box, said that the time capsule was a great treasure. “This is a wonderful educational resource(资源）. We can learn so much about our history,”he said. “I never knew my grandfather, but now I feel very close to him. ”

TOKYO, JAPAN--What do you do when you see a cockroach (蟑螂）？Do you hit it with a newspaper? Do you step on it?
When researchers at Tokyo University see a cockroach, they take the remote control and make the cockroach turn around, run left or right, or go forward. These scientists are changing the cockroaches into robots. Each cockroach has a very small pack that has in it a microprocessor(微处理器）.Then researchers can send signals from the remote control to the pack. The signals control the movements of the cockroaches.
Why does anyone want to control a cockroach? “Insects can domany things that people can’t,” says Isao Shimoyama, head of robot research at Tokyo University. In a few years, he says, these robot insects will carry very small cameras. They will be able to move through earthquake rubble(瓦砾）to look for people or move under doors to find information about someone.
This may seem strange, but the Japanese government thinks the research is very important. The government is giving the scientists $ 5 million for this research.
First, the researchers breed (培育)hundreds of cockroaches. They use only the American cockroach because it is bigger and stronger than other cockroaches. Then they choose the best cockroaches and remove their wings and antennae(触须）. They put small packs where the antennae were. The packs weigh about three grams, or about two times the weight of the cockroaches themselves. “Cockroaches are very strong,” says Ralph Holzer, who is a researcher at Tokyo University. “They can lift 20 times their own weight. ”
With a remote control, the scientists send signals to the packs. When a cockroach gets the signal, it moves. The problem is that the cockroaches don71 always move in the right direction.
