Want a good night's sleep? Then turn off your computer, cell phone or PSP two hours before you go to bed.
These things have bright lights. When our eyes see bright lights just before sleep, our sleep patterns (模式) change, a study has found.
Our body clock starts shutting us down for bed at 9 or 10 pm. But bright lights make our minds think that it is still daytime. That wakes us up and leaves us sleepless, experts say.
But if you read a paper book before sleeping, you won't have this problem. This is because light from a bedside lamp (臺燈) does not go straight into our eyes.
Also, if you are watching a television from across the bedroom, you won't have problems falling asleep. The TV sends light to us from a distance, so the light won't be as strong.
小題1:The writer tells us to turn off the computer         before bed time.
A.half an hourB.an hourC.two hoursD.three hours
小題2:Which of the following may make us sleepless?
A.Reading a newspaper.B.Talking on QQ.
C.Reading a book.D.Watching TV.
小題3:Why can't we sleep well if we use a computer before bed time?
A.We think it is daytime if we leave computers on.
B.We feel too excited to sleep after using computers.
C.Lights from computers are brighter than other lights.
D.Lights from computers can change our sleep patterns.

小題1:C
小題2:B
小題3:D

In every school there is “top” crowd that sets the pace, while the others follow their lead. For example, if the crowd decides that it is smart to wear bright red sweaters, then very soon everybody is wearing bright red sweaters.
There is nothing wrong with that, except the fact that for some people bright red sweater is really unsuitable.
The situation can even become dangerous, if the top crowd decides that it is smart to drink and to drive cars at seventy miles an hour. Then the people who follow the lead are endangering their lives. They are like the sheep being led to the slaughter(屠殺).
Now it’s possible that you have come across situations like these more than once in your life. In fact you probably did something you knew to be wrong one time or another. You may have excused yourself by saying, “ Gee, the crowd does it.” Well, let the crowd do it, but don’t do it yourself. Learn to say “No”.
Develop your own standards(標準)and your own judgment. If you know the crowd is planning something you disagree to, you’d better take the courage to bow out in a polite way. You’ll have the satisfaction of standing on your own two feet.
小題1:The main idea of the passage is that _____________ .
A.in every school there is a “top” crowd that sets the pace
B.it’s a mistake to follow the “top” crowd blindly
C.people who follow the “top” crowd are endangering their lives

小題2:The author(作者)doesn’t think it good wearing red sweaters if _______.

Learn to relax. Overwork is the main reason why so many students feel tired. Cut down some of the jobs you need to do each day so that you only do the most important things well. Leave time for activities that are relaxing and fun. This might mean reading a good book, listening to the music, going for a walk or taking a relaxing bath. You will feel very good.
Get a good night’s sleep. Getting enough sleep will help you keep your body and mind﹡ in the best form﹡. If you stay up late and need to get up early for school the next day, you may not be able to pay attention﹡ to the things you need to do. You also feel tired.
Exercise regularly and eat well. Don’t rush through your meals. Eat less junk food or fast food. Eat healthy food instead. Fruits and vegetables are necessary.
Get to know pleasant people. Some people are optimistic, while others are not. Choose optimistic people as your friends and spend more time with them and you’ll be as happy as them. You’ll see everything with the optimism.
Learn to be calm when you face any problem. Find out the best option from those that are in your mind. Knowing that you are able to solve problems is a good way to build up your self-confidence﹡.

根據短文內容,判斷句子正(T)、誤(F)。
Most animals are helped by people. They can’t live without us. But sometimes people have made the environment worse. For example, in some parts of the world the forests are being cut down.
The animals in the forests have become fewer and fewer. People hope to grow more food on the land, but the wind blows the earth away. Now forests become smaller and smaller, the soil becomes poorer and poorer. Now there are fewer animals and plants in the world. Insects (昆蟲) are usually killed, but some plants need insects. Their seeds (種子) can’t spread without them. Birds eat insects, and without insects many kinds of birds will die.
There are hundreds and hundreds of plants and animals, and each plant is helped by another, so does each animal. If you hurt one, you will hurt another, then another. Scientists know this well. They don’t want people to break their environment.
小題1:It isn’t good for our environment to cut down forests.
小題2:Animals in the world are becoming fewer and fewer.
小題3:Animals and plants helped by each other.
小題4:After the wind blows, the earth becomes richer and richer.
小題5:This article tells us it is important to make our environment worse and worse.

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    ______.
A.weight that high school students gain
