The scientists from the Lockheed Space Company (公司) work in Felton, California, with the help of a computer. But the computer is placed in Sunnyside, about 80 kilometers away. What the scientists input is sent by telephone lines to the computer, and after a time, copies of the designs are needed back in Felton as possible. Lockheed people have tried several ways of sending the prints (印刷品), but the most effective seems to be by pigeon (鴿子). Are pigeons really used to carry messages in these days? They are, and they send the prints faster and cheaper than any other way.
Human (人類的) messengers (persons carrying messages) are much more expensive and slower than the pigeons. The road to Felton goes through the mountains, and the driving is not easy. An electronic printout system(電子印刷系統) could do the work in Felton, but at a cost of 10 dollars a print. Pigeons carry the designs for about 1 dollar each.
Now Lockheed people have ten pigeon messengers. The pigeons do the work, and they have made Lockheed more famous. You can often read the news about the pigeons in the newspapers around the world.

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(供應)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.
Eating right
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.
小題1:The “freshman fifteen” is    ______.

閱讀下面短文,判斷正誤。(10分)
What a cold winter! How wonderful it would be if there were a fire! Fire keeps us warm. But fire is very dangerous, and can kill us. November 9 is National Fire Safety Day. It's a time for us to learn a lot more about fire, especially what to do if we are caught in a fire.
Call 119
Never try to put out a fire by yourself, even if it is a very small one. Get help from your parents or call 119. Tell 119 where you are and what is on fire. Listen to 119's instructions.
Keep down close to the floor
If there is a lot of smoke in your room, keep down close to the floor. There is less smoke down there, so it's easier to breathe(呼吸) and see where you are going. If you don't, the smoke may kill you before the fire does.
Don't use the elevator
Never use the elevator(電梯) during a fire. Always use the stairs. An elevator may stop at the floor where the fire is burning. It may also go wrong and keep you inside.
Don't go back
Never go back into a burning building. Even if you have left your pet or favorite toy inside, do not go back for it. Don't worry about your pets. Animals have a very good sense of smell(嗅覺). They often get out of the building before people.
