American Classroom Rules
1. If the teacher asks a question, you should give an answer. If you do not understand the question, you should put up your hand and ask the teacher to repeat the question. If you don’t know the answer, it’s all right to tell the teacher that you don’t know. Then he or she knows what you need to learn.
2. There is no excuse for not doing your homework. If you can not go to school, you should call your teacher or your classmate and ask for the homework. It is your responsibility（責(zé)任）to find out what homework you have missed. It is not the teacher’s job to remind you of missed homework.
3. You must not be absent(缺席) on a test day. If you are badly ill, call and let the teacher know you will not be there for the test. If your teacher allows you to take a makeup, you should take the test within one or two days after you return to class. Bad illness is the only reason for missing a test.
4. Be on time! It’s not polite to be late. Also, it bothers other students. If you must come in late, be sure to do it quietly. Have your books out of your bag before you come into the classroom. Then go to your seat and sit quietly. In the US, it is not necessary to knock at the door before you come into the classroom.

I can’t remember when I started collecting litter（垃圾）. But it was when I got tired of seeing litter near my home and realized that no one else was going to pick it up.

I made my first trip to clean the forest that afternoon. I took a big black rubbish bag with me. Ten minutes after starting to pick up litter, my bag was full! It had cans, bottles, broken glass and newspapers in it.

The world itself is becoming much smaller by using modern traffic and modern communication. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution.
To pollute means to make things unfit or unclean to use. Pollution comes in many ways. We see it, smell it, drink it and even eat it. Pollution is beginning to threaten (威脅) our health, our happiness and our life.
Man has been polluting the earth from the time he first made fire, washed his clothes in the river and threw his waste on the ground. When land was used up or water became dirty, men moved on to another place. At first, the problem was not so serious because there was plenty of clean air, land and water. There weren’t so many people then and their wants fewer. All the dirty things could be absorbed(吸收) by nature and soon covered over. But this is no longer true. The increase of pollution and the development of industry(工業(yè)) have changed that. Man is slowly poisoning(毒害)not only his environment but also himself.
Through the use of poison, man has polluted the land, killing the animals. By putting dirty water and chemicals into rivers and lakes we have polluted our drinking water, killing the fish.
Our increasing population is part of the problem. More people, more waste.
Where is this all to end? Are we turning the world into a big rubbish dump(堆存處)，or is there any hope that we can get rid of (擺脫，除去) the pollution? Luckily, millions of people have been warned of the danger of pollution. Large numbers of people are now working hard to bring pollution under control.
The earth is our home. We must take care of it. This means keeping the land, air and water clean. And we must take care of the rise in pollution at the same time.
小題1:Which of the following is NOT true according to the passage?
A．We live on the earth, so we should look after it.
B．Man is fighting against different kinds of pollution.
C．To pollute means to make air, water and land unfit for use.
D．All the waste produced by modern industry can be absorbed.
小題2:In Paragraph4, the underlined word “chemicals” mean ____________.
A．化學(xué)物質(zhì)B．醫(yī)療器械C．污染源D．塑料制品
小題3:Through the uncontrolled use of poison man has___________.
A．made the drinking water dirtyB．polluted the land
C．killed the animals D．a(chǎn)ll of the above
小題4:From the sentences “More people, more waste.” We know that ___________
A．we need more people, not more waste
B．the increase of population caused more waste.
C．there isn’t any hope that we can get rid of the pollution
D．More people have been warned of the danger of more waste.
小題5:Which of the following is TRUE according to the passage?
A．Man begins to understand the pollution.
B．Man doesn’t know how to control pollution.
C．Man is doing something to control pollution.
D．Man still doesn’t realize how serious pollution is.

People are busy working every day, so they do not have enough time to do exercises. As a result, many people become too fat or too thin. To keep our bodies healthy, we have to do exercises every day.
There are many kinds of exercises. Bending (彎腰) and stretching (伸展) helps us move easily. Before we play ball games or swim, it is better for us to do bending and stretching exercises first. This kind of exercise is sometimes called warm-up exercise. Running is also a good exercise. If we cannot run fast, we can Jog. Jogging means running slowly. Again, before we run or jog, we must do warm-up exercises. Also, we should not run or jog in busy streets. The air there is often dirty. Some people like weight lifting (舉重)because it can make their bodies strong. Also, we need to do some warm-up exercises before weight lifting.

Children can spend hours a day looking at computer screens and other digital devices. Some eye doctors say this leads to an increase in “computer vision syndrome(電腦視力綜合癥).”
Nathan Bonilla-Warford is an optometrist（驗光師）in Tampa, Florida. He has seen an increase in problems in children. “A lot more children come into the office either because their parents have noticed that they have headaches or red or watery eyes or discomfort, or because their nearsightedness appears to be increasing and they’re worried,” he says.
Dr. Bonilla-Warford says part of the problem is that children may be more likely to pay no attention to early warning signs than adults. “Even if their eyes start to feel uncomfortable or they start to get a headache, they’re less likely to tell their parents, because they don’t want to have the game or the computer or whatever taken away,” he explains.
He says another part of the problem is that people blink（眨眼）less often when they use digital devices. He says, “A person who uses an electronic device blinks about one third as much as we normally do in everyday life. And so that can result in the front part of the eye drying and not staying protected like normal.”
Eye doctors offer suggestions like following which is known as the 20/20/20 rule. That means every twenty minutes look away twenty feet or more for at least twenty seconds from whatever device you’re using.
Other suggestions include putting more distance between you and the device and using good lighting. Of course, another way is to spend less time looking at screens. Many experts say children should spend no more than two hours a day using digital devices—with no screen time for children under two.
But not all eye doctors have noticed an increase in problems in children. Dr. David Hunter, from Children’s Hospital Boston, has not seen an increase in his practice. “While it is possible to develop fatigue looking at screens for a long period of time, there’s certainly no proof that it actually causes any damage（傷害）to the eyes.” he says.
小題1:Which of the following is true according to the passage?
A．Dr. Bonilla-Warford thinks using computers causes nearsightedness.
B．People keep their eyes protected against drying by blinking normally.
C．Children under two can watch TV for less than two hours a day.
D．Dr. David Hunter says headache causes an increase in eye problems.
小題2:What does the underlined word “fatigue” mean?
A．InterestB．AbilityC．Tiredness.D．Difficulty.
小題3:What can be the best title for the passage?
A．Looking at Screen: Two Hours or More
B．How Can Children Use Their Eyes Properly
C．Using Digital Devices: Advantages and Disadvantages
D．How Much Screen Time Is Too Much for Children

Earthquakes happen without warning(前兆). They can happen any time of a day, at any point during the year. When an earthquake is happening, you should know what you should do or not do.
Do NOT go outside. You could get injured from falling glass or parts of buildings. If you are outside, stay away from buildings and power lines(輸電線).

Keep away from windows, pictures or advertisements on the wall or the building, and anything else that could fall and hurt you. Most people get injured by falling things during an earthquake, not by the shaking itself.
Also keep away from a fire. You could fall down and burn yourself on the fire.

We talk every day. When we have good news, we like to share it with our good friends and when something terrible happens, we tell it to others soon. But can you imagine that a tree can talk and share news too ? Of course, no tree moves lips and says words just as people do. Strange as it may sound, though, some trees do manage to communicate with each other.
Willow (柳樹) trees are the best-known of these trees. When insects begin nibbling (叮咬) a willow tree, the tree sends out a special smell at once. This smell tells the other willows that harmful insects are coming near. All of them quickly make a chemical (化學(xué)物質(zhì)) in their leaves. This chemical is bad to the insects. The insects do not like it and they fly away soon. In this way, the willow trees protect themselves from the insects.
The next time when you take a walk in the woods, maybe the trees are “talking” to each other quietly. And when someone says that trees cannot “talk”, please tell them that even trees give messages to each other, too.
小題1:Willow trees send messages with_____________.
A．wordsB．movementsC．smellsD．sounds
小題2:The underlined word “l(fā)ips” in the first paragraph means _____________.
A．樹干B．嘴唇C．枝條D．手勢
小題3:The passage tells us that some of the trees can _____________.

C．communicate with each otherD．kill insects in the woods
