A student newspaper reports that most students go to sleep at 1:30 am. Even if that’s an overstatement (夸張), it’s close to the truth. Scientists say teens should sleep nine hours each night. But that’s hard. Some are even “pulling all-nighters” (開夜車). These students must hand in their homework the next day but they haven’t done it. In the morning they don’t look healthy and you can tell who’s been doing it. One of my classmates did a survey on the topic. She found that most kids pull all-nighters to finish homework, but some do it for other reasons, such as playing computer games!
Maybe our lack(缺乏) of sleep is because of laziness — I think I’m a rather lazy student — or maybe it’s because we have too much to do in American high schools. I usually go to bed around midnight. If I stayed up past 1:30 am, I wouldn’t get any work done. I’d be falling asleep at my computer. My classes begin at 7:30 am. I’m partly awake in my first class. By the second, I’m a little sleepy. By my third class, I’m sleepy. By midday I’m finally fully awake. But by 3:00 pm, I’m slowing down again. Yet I get more sleep than usual students.
Most American high schools seem to have a similar(相似的) problem with sleepy students. High school classes start at 7:30 am, so students have to get up one and a half hours before that to get ready and catch the bus. It’s believed that lack of sleep can be bad for both grades and health. Some schools are paying attention. Classes in those schools start at 8:30 am.
小題1:What does the underlined sentence “it’s close to the truth” mean?
A.It doesn’t tell the truth. B.It is quite true.
C.It is impossible.D.I don’t think it’s right.
小題2:Why do most of the teens have to stay up late?
A.They play computer games.B.They watch videos late.
C.They have to do a lot of housework.D.They have to do a lot of homework.
小題3:When do students in most American high schools have to get up?
A.At 7:30 am.B.At 6:00 am.C.At 9:00 am.D.At about 7:00 am.
小題4:Which of the following is TRUE according to the reading?
A.The writer usually stays up past 1:30 am.
B.The writer usually goes to bed around midnight.
C.The writer usually does a survey.
D.Many American students don’t get enough sleep, so they can have high grades.
小題5:What’s the main idea of the passage?
A.Something has to be done to solve the problem of students’ lack of sleep.
B.Many American high school students are sleepy in class.
C.Many kids have too much homework to do.
D.Students can’t play computer games.

Answer the questions(根據短文內容回答下列問題)
Your Nose is Busy and Important
Your nose has many important jobs, and is always busy.
Smelling
Smelling helps you gather information about the world around you. A good scent (氣體),like flowers, brings you pleasure. A bad scent, like smoke or sour milk, warns you of danger. Most things around you release scent particles (微粒) into the air. These invisible chemicals enter the nose when you breathe. Nerves in the nose send information to the brain to identify a smell. You are able to recognize thousands of smells.
Breathing
Most of the air you breathe enters through your nose. The nose uses hair and mucus (粘液) to clean dust and germs (細菌) out of the air. The air that enters your nose contains oxygen. Your body uses oxygen to unlock the energy in the food you eat.  Even when you sleep, your body needs energy to keep your heart beating and your brain working.
Tasting
Your nose helps you enjoy food. Flavor is a mixture of taste and smell. The smell of the food helps you identify what you are eating. The sense of smell contributes more to (貢獻) food flavor than the sense of taste .When you are sick and have a stuffy nose, your food doesn’t taste as good because without smell, food loses most of its flavor.
Smell memory
Smells can bring back memories. Your brain uses a process to create a picture in your mind from the odors(氣味)you smell. Smells can affect your feelings because the part of the brain that helps you identify smells is close to the area that affects your emotions, mood and memory. More smell memories are collected as you get older.
Your nose has many important jobs, and is more than just a smeller!
小題1:How many important jobs does a nose do according to the passage? What are they?
小題2:Smelling helps you recognize thousands of smells, doesn’t it?
小題3:What does the nose use to clean dust and germs out of air?
小題4:What happens to your food if you are sick and have a stuffy nose?
小題5:How do smells bring back memories?
小題6:What do you think of your nose? Why do you think so?

Everyone needs friends. There is an old saying “Friends are God’s way of taking care of us.” But how do you find real friendship and keep it?
The American writer Sally Seamans tells young students some smart ways to find friends. Sally says finding friendship is just like planting a tree. You plant the seed and take care of it to make it grow.
First, you should choose a friend. What makes a Good friend? It is not because a person has money or good looks. A good friend should be kind and patient. For example, if you have a bad day, a good friend should listen to your complaints and do his or her best to help. To make a friend, you can not be too shy. You should make each other happy and share your lives. But things cannot always be happy. Even the best have fights. What should you do when you have a fight with your friend? You have to talk to him or her. When there is no one around, have an honest talk. If he or she doesn’t want to talk, you could write a letter.
There are three steps to being friends again:
Tell him or her how you are feeling ; say what your friend has done wrong, and explain why you did this or that. Remember that friendship is the most important thing in your life.
(   ) 1. Sally wants to tell students the ways to ________.
A. find friends    B. plant trees   C. get happy    D. keep fit

This is not a diet. It’s a simple way to lose weight. And you don’t even have to give up the food you love or join a gym (參加體育鍛煉). You just follow some habits that thin people have. Keep them, and you’ll become thin.
(1) Wake - up
When you wake up in the morning, sit up slowly without using your hands. With legs straight out, bend(彎曲) forward until you feel sore(酸痛) in your back. It will burn about 10 calories.

Apples are full of fiber(纖維) and water, so your stomach will want less. The study shows that people who eat at least three apples a day lose weight.

We often give our personal information to stores. That     86     our birth date, personal ID number, and home address. When we apply for a store membership, we give our information to a stranger. When buying something online, we do the same thing.
87    work hard to get that information. They- steal receipts(收據) and     88     computers. They also try to steal our passwords. They can use that information to become" another person. That’s identity theft.
One common crime is to apply for a credit card using     89     else’s name. The thief buys expensive things but doesn’t pay the bill. That can hurt a victims credit. With bad credit, it’s harder to get bank or car loans.
90     can you prevent identity theft? First, be careful about giving away personal information.    91    give someone your birth date and personal ID number when necessary. Second, tear up old credit card receipts and bank statements if you don’t want them. Finally, some experts recommend paying in cash as much as possible.

It was the last day of final examinations at a large college. On the steps of one building, a group of engineering students were discussing the exam that was ahout to begin. On their faces was confidence. This was their last exam before they graduated(畢業)and found jobs.
Some talked of jobs they already had,others of jobs they would get. With four years of college study,they felt ready and able to conquer(征服)the world.
The coming exam,they knew,would be easy. The professor(教授)had said they could bring any books or notes they wanted,but they couldn’t talk to each other during the test.
They walked into the classroom. The professor passed out the papers. The students’ smiles became wide as they saw that there were only five essay-type questions.
Three hours passed and the exam came to an end. Then the professor began to collect the papers. The students no longer looked confident. They seemed worried. No one spoke as the professor faced the class with the papers in her hand.
She looked at all the worried faces in front of her, and then asked,“How many students completed all five questions?”
Not a hand was put up.
‘‘How many of you answered four?” Still no hands.
“Three?Two?”The students moved restlessly in their seats.
“One,then. Certainly somebody finished one.”But the class stayed silent. The professor put down the papers.“That is just what I expected,”she said.
“I just wanted to make sure you realize that even though you have studied engineering for four years, there are still many things about the subject you don’t know. Instead of testing you on what you learned in this class, I’ve given you questions that skilled engineers face in the world outside the classroom. You can’t expect to be an expert(專家)on the day you graduate. You have to learn as you go.”
Then,smiling, she added,“You will all pass this course, but remember that your education has just begun.’’
小題1:What does the underlined word“restlessly”mean in the passage?
A.confidentIyB.proudlyC.excitedlyD.nervously
小題2:Why did the professor design the final exam in such a way?
A.To make the students realize that they still had much to learn after graduation.
B.To find out whether the students could put what they had learned into practice.
C.To show that she had much more knowledge than her students in engineering.
D.To examine whether the students learned what they had been taught in her class.
小題3:What can be the best title of the passage?
A.A Playful JokeB.A Lucky Chance
C.A Strange ProfessorD.A Special Exam

Swimming and English Learning
Can you swim? Do you like swimming? Yes? Well, how can you learn to swim? I think the best way is to go into the water and learn. I’m afraid you’ll never learn to swim just by reading books about swimming or looking at others swimming. It’s the same with the English study. We must practice, practice and practice.
Listening and speaking are very important for beginners. The children in English-speaking countries first listen to others. Then they try to imitate and speak. We can listen to English programs on radio. You may just understand a few words. It doesn’t matter. Just be relaxed, try to catch every word.
Somebody may be a good listener. But he dare not speak. He’s afraid of making mistakes. You know we sometimes make mistakes when we speak Chinese. Don’t be afraid. We must be brave(勇敢). If you really want to learn English well, you must try to speak with everyone so long as he knows English. Whether you know him or not is not important when there’s nobody to talk with, you can talk to yourself in English. It’s interesting and also a good way to practice your spoken English. Remember, the more you speak, the fewer mistakes you’ll make.
Reading and writing are more important for senior school students. First we must choose the books we’re interested in. A lot of reading will improve your language sense. This is the most important.
Keep writing English diaries. We can also write English articles. You may even post them to English magazines. Don’t be afraid of failure. Failure is the mother of success.
Easier said than done. Well, let’s do more practice from now on. I’m sure you’ll learn English well in this way.
(   ) 6. You can learn to swim by_______.
A. reading books about it  B. looking at others swimming
C. having lessons on it    D. going into the river and learning
(   ) 7. We should learn English by _______.
A. listening and speaking       B. reading and writing
C. A and B                  D. swimming
(   ) 8. What will you do with mistakes when you speak?
A. Don’t make mistakes.          B. Study hard
C. Try not to speak English        D. Don’t be afraid.
(   )9. What’s more important for senior school students?
A. listening    B. speaking    C. reading and writing   D. learning
(   ) 10. We can listen to English ______, according to the passage.
A. by train     B. on the radio   C. every minute   D. now and then
