Can you imagine astronauts' everyday life in space? They also need to eat,  sleep, exercise and relax. They do the same things as us, but they do them differently.
On Earth, we put food on a plate. Gravity holds the food down and keeps it on a place. But there is almost no gravity in space, so food can float （漂�。゛way, and astronauts must eat carefully.
Sleeping is very different in space. Some astronauts like to float in the air, but most like to be in a sleeping bag. They tie the bag to a wall so that they won't float away at night.
Exercise is very important in space. On Earth,  your legs carry your body,  but in space, astronauts float, so they do not use their legs often. This is very bad for their legs, so they must exercise for thirty minutes every day.
After a day's work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families on the radio. Sometimes they just enjoy floating in the air.
【小題1】What does the underlined word "gravity" mean in Chinese?

Dolphins are not fish. They are mammals (哺乳動物).They live in groups and speak to each other in their own language. But they are quite different from almost all land animals. Their brain(大腦)is as big as men's and they live a long life at least 20 or 30 years.
Like some animals, dolphins use sounds to help them find their way around. They also use these sounds to talk to each other and to help them find food. They do not use their ears to receive sounds,but use the jaw--the lower part of the mouth.
It is strange that dolphins are friendly to men, and for thousands of years, there are many stories about dolphins and men. In the 19th century, in a dangerous part of the sea near New Zealand,there was a dolphin. The seamen liked him very much and gave him a very good name, Jack. From 1871 to 1903 ,Jack met every boat in the area and showed it the way. In 1903 a passenger on a boat with the name of The Penguin shot and hurt Jack. Luckily the dolphin didn't die, and after a long time he was well again. He guided the ships through the area for nine more years, but he refused to help the boat of the Penguin.
Today, some people still kill dolphins, but many countries in the world now protect them. In these places, people are not allowed to kill them.
【小題1】The word "jaw" means_________in Chinese.

The sea looks very beautiful when the sun is shining on it. But it can be very terrible when there is a strong wind. The sea is very big. It covers three quarters of the earth. The sea is also very deep in some places. In one place, the sea is about 11 kilometres deep. The highest mountain(山) in the world is about nine kilornetres high. If that mountain was put into the sea at that place, there would still be two kilometres of water above it!
In most parts of the sea,there are plenty of fishes and plants (植物). Some live near the top of the sea.Others live deep down. There are also a lot of small living things,and lots of fish live by eating them. The sea can be very cold. When people go down, the sea becomes colder and colder. Only some men can go down into the deep sea. But,in 1970,five women scientists lived in the deep sea for fourteen days.
【小題1】This writing is ________.

Germs(細菌) are everywhere. You can’t see them, but they are on your desk, on your computer, and even in the air!
Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.
Warmer Weather Brings Germs  
The world’s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people.
Under Your Skin
Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
Fighting Germs
Your immune system(免疫系統(tǒng)) protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells(細胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies(抗體). Antibodies help your body find and stop germs.
What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.

Cats are the most popular pets among Americans. So it is not surprising there are many expressions about cats. Do you know any of them? Now let me introduce some to you.
Some cats like to catch small birds, like canaries. If someone looks very proud or satisfied with himself, we say he looks like the cat that ate the canary.
Sometimes, a cat likes to play with a small animal it catches. So if you play cat and mouse with someone, you change between different kinds of behavior when dealing with another person. For example, a child might offer something sweet to her little brother, and then take it away when reaches for it.
A cat will often catch a small animal and present it to its owner. The saying “that looks like something the cat dragged in (把…拖進來)” describes something in bad condition.
A fat cat is a person with a lot of money.
There are many other expressions about cats in America. How interesting! Which kind of cat are you, or which kind would you like to be?
【小題1】Americans don’t like cats as pets very much.
【小題2】The canary is a kind of bird.
【小題3】If you have much money, we can call you a sad cat.
【小題4】We can say he looks like the cat that ate the canary if someone is very pleased with himself.
【小題5】The passage introduces us four expressions about cats.

Which animal do you think is "the king of the animals", the elephant, the lion or the tiger? They are all large and strong. But I think the tiger is "the king of the animals". If you watch carefully, you can find some black lines on the tiger's forehead(前額). The lines look like the Chinese word "WANG". The word means "the king of the world" in Chinese.
Most of the tigers come from China and India. Tigers are dangerous animals. They look scary(嚇人的). They like eating meat. They have yellow fur with black lines. They usually weigh about 200 to 300kg. Tigers can run fast. They run at a speed of 20 meters per second.
Some people think they are dangerous. But they don't know tigers are in danger now. There are only 20 to 30 wild South China Tigers in China and less than 300 in the world. Lots of people kill them for their fur. We should take action to protect them.
【小題1】Which animal does the writer think is "the king of the animals" ?

The human body is a living machine, and, like all machines, it needs “fuel” to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?
The energy value of food is usually measured in calories(卡). A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.
The energy in food is in the form of three kinds of chemical materials—carbohydrate（碳水化合物）, protein（蛋白質(zhì)） and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show.
(P= protein      C= carbohydrate    F=fat)
【小題1】How many calories are needed to raise the temperature of 5kg of water from 35℃ to 90℃?

Why do we need to throw less away? There are two reasons. One is that some resources（資源）are nonrenewable（不可再生的）. That means there is only a certain amount of that resource in the world. One example of these resources is oil. When we use up all the oil in the world, there will be no more.
There is a second reason for throwing less away. All of our trash has to be put somewhere. Often, it is put into garbage dumps（垃圾場）. Much of that trash will be there for hundreds of years. The dumps ill be filled up with all this trash.
There are three ways to cut down on trash.
One way is to recycle. When you recycle something, it means it is made into another shape and used again. Old newspapers may become paper bags. A glassware can be melted（熔化）and made into a bottle.
Another way to cut down on trash is to reuse things. You can wash and use a bottle again that can hold mustard（芥末醬）or something else.
The third way to cut down on trash is to reduce the amount of trash you make, for example, stopping buying things that you don’t need in the first place. That reduces the amount of the earth’s resources.

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 live close to a forest in Ohio, America. I can walk there in three minutes! I used to love going there to play with my dog. But one day there was so much litter there that I became very unhappy. I decided to clean up the forest. I wanted to feel happy going there again.
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.
Since that first trip three years ago, I’ve gone to the forest four times a year to pick up litter. I’m often there for three hours. It makes me feel great to do something for the environment.
After each trip, I look at all the litter I’ve found. If any of it is recyclable（可回收的）, I keep it. I can’t understand why people drop litter. But I will keep picking it up until they stop dropping it.
I know I can only do a small bit to help the earth, but I still think it is important.
