In order to reduce the waste in your classroom. Make a goal to form new classroom habits. The new habits you form can protect the environment. Check out these new habit ideas for reducing the waste in your classroom.
Recycling Cut back on the rubbish you throw away. Get a large box or bin. Place the bin next to the garbage can. Throw the paper into the bin instead of throwing the paper here and there. Take the bin to a recycling center once the bin is full of paper. Many schools earn money for the waste paper they are able to collect and recycle. Help your school by recycling paper.
Reducing Reduce the paper you use. Make it a habit to write on both sides of your notebook paper. Also try writing your words smaller so you can fit more on the paper. The more words you can fit on both sides of your paper, the less paper you will need. Do not write too small, because others need to be able to read your handwriting.
Saving Turn off the lights when you are not in the classroom. Also, turn off computers when they are not being used. Closing the window blind will also help save energy.
Reusing Use paper from the recycling bin. Create art projects or paper for math problems. Turn your classroom waster into treasures!
By doing these over and over again, the habits will become part of what you do without even thinking about doing them.

The earth is our home. We must take care of it. Life today is easier thanit was
1 years ago, but it has brought some new problems. One of the biggest problems
is pollution（污染）. We can see it, smell it, drink it andeven 2 it. Man has polluted
the 3 . The more people, the more pollution.Many years ago, the problem was not so serious because there were not so 4people. When the land was used up (用光), the
river was not clean in a place,man went to 5 place. Now man is slowly polluting
the whole world.
6 pollution is still the most serious, it’s bad for 7 things in the world.Many
countries don’t let people burn 8 for air in houses and factories in the city. Pollution
by SO2 is now the most dangerous kind of 9 pollution. It’s caused by heavy traffic.
People say it’s 10 to ride bikes. When you are11, there is no pollution. But even in
developed countries, most people don’t go to work by bike. It’s not 12 bikes are expensive or people are tired if they ride to work. It’s because the number of cars on the roads becomes larger. So more people 13 their bikes and go to work by cars, then
things are getting 14 . We should have special roads only for bikes and make it 15
difficult and expensive for drivers to take their cars into the city that they will go back to use their bikes.

If you watch the sky for about an hour after the sun goes down, you may see some “moving stars”. But they’re not real stars. They’re man-made satellites(人造卫星). And the biggest of all is the International Space Station (ISS). From May to July is the best season to watch the ISS flying over the earth. And people can see it with their eyes.
The ISS is the biggest satellite and scientists want to live on it. They think that the best way to learn more about space is to live there.
When the space station is finished, it will be like a city in space. People will stay and study there with many of the things they have at home. Laboratories, living rooms and power stations are being built. The ISS is the most expensive space program. Billions of dollars are being spent on it every year.
Scientists hope that the ISS will be a stepping stone for future space exploration(探测). “The ISS will help us understand the human body better, explore space and study the earth. It can help us make life on the earth better,” said Kathryn Clark, an ISS scientist.
Sixteen countries are part of the program: the US, Russia, Canada, Japan, Brazil and 11 European countries. China isn’t an ISS country, but it has helped with some of the experiments. In 2003, China sent some rice up to the ISS to find out what space would do to it.

There are eighteen kinds of bats in Britain and all of them are endangered（濒临绝种的）. The greater horseshoe bat is one of them. There are few of them because people pull down old buildings and cut down trees. They have no place to live in. There are only about 5,000 bats in the UK now.
The Amur tiger（东北虎）is in danger. People kill them for their meat and fur. They also cut down trees and make them homeless. In the 1930s, there were only 20 of them. Then people began to realize that they should protect the Amur tiger. Now there are about 360 Amur tigers in the world. About 20 of them are in China.
People may see the mandarin duck（鸳鸯）on pools and lakes in Britain, but its native home is across Eastern Asia, in Russia, China, Korea and Japan. The mandarin duck is on water near forests. However, forests and rivers are disappearing (消失). It makes the mandarin duck fewer and fewer.

For people who are interested in space, nothing is more exciting than the idea of life on other planets(行星). At first, when Mars showed signs of having life, everyone was excited. The idea has produced many films and stories including The Martian (《火星救援》), which shows a man tried his best to live on Mars. But would it actually be possible to live there?
Although the idea of living on Mars is great, the reality does not look as good. Mars does not have a friendly atmosphere (大气) for humans. There is very little oxygen (氧气) there, and because it is farther away from the sun than the earth, it is also very cold. The temperature on Mars can be -62℃on average. This is much too cold for humans.
However, scientists say it might be possible to live there without an atmosphere. The daytime of Mars is similar to the earth’s, which means there’s enough sunlight to grow plants inside safe buildings. However, they would have to grow in soil(土壤) from the earth. Mars does not have a strong enough atmosphere to stop the radiation (辐射) from space, which makes it dangerous to grow things in the soil.
Also, the radiation causes problems for our health. One way we could live with the radiation and cold temperatures would be to build homes under the ground or within the rocks on the planet. These would give humans the heat and protection the planet doesn’t have.
Although it’s a long time before we would be able to live on Mars, NASA is hoping to make some progress within the next 20 years.

Zhalong is a nature reserve in Heilongjiang in northeast China. It is one of the world’s most important wetlands. The area provides food and shelter for wildlife. It is an ideal home for different kinds of plants, fish and birds.
Many birds live comfortably in Zhalong Nature Reserve all year round, while some only stay for a short time. There are many fish in the wetlands, and the birds can easily catch them for food. Zhalong Nature Reserve is an important living area for the rare red-crowned cranes. There are not many red-crowned cranes in the world. Some of them live in Zhalong.
Some people want to change the wetlands to make more space for farms and buildings. This means that there will be less and less space for wildlife.
More and more birds are in danger because they do not have enough living space. Many of them died. The Chinese government wants to protect these endangered birds, and they can be safe in Zhalong.
Every year a lot of tourists go to Zhalong to watch birds. This year members of our Bird watching Club are going to study the different kinds of birds in Zhalong and the changes in their numbers. The study begins next month.
We do a bird count once a year. We are now inviting secondary school students to help. We need more people to help us count and do something to help the birds. Many people do not understand the importance of the wetlands. We hope this information will help them understand and make them actively take action to protect wildlife.

The moon travels around the earth. Most nights, the moon is the brightest thing in the sky. This is because it reflects(反射) light from the sun. It's hot during the day on the moon. When the sun is overhead, the temperature is 243℃. At night, the temperature drops. The temperature at night maybe -163℃．A sunny day on the moon could kill you. But then, so could the night.

There are many wetlands（湿地）in China and some of them have become the world’s important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home for many different kinds of birds and
(milu deer) animals. The world’s largest Milu Deer Nature Reserve（自然保护区）in them. More than 700 milu deer live freely there. There are not many red-crowned cranes in the world, but every winter you can see some in the Red-Crowned Cranes Nature Reserve in the Yellow Sea Wetlands.
The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine, too. They are really good places for wildlife(野生生物). Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.
Luckily, more and more people are beginning to realize the importance of wetlands and wildlife. Every year, on February 2nd, many activities are held to tell people more about wetlands. (red-crowned crane)

More than 50, 000, 000 people live in the rainforests of the world and most of them do not hurt the forest they live in. They eat the fruits that grow on the forest trees, but they do not cut them down. They kill some animals to eat, but they do not destroy them.
When we cut down the rainforests, we destroy these forest people, too. In 1900, there were 1, 000, 000 forest people in the Amazon forest. In 1980, there were only 200, 000.
The Yanomami live along the rivers of the rainforest in the north of Brazil (巴西). They have lived in the rainforest for about 10, 000 years and they use more than 2, 000 different plants for food and for medicine. But in 1988, someone found gold in their forest, and suddenly 45, 000 people came to the forest and began looking for gold. They cut down the forest to make roads. They made more than a hundred airports. The Yanomami people lost land and food. Many died because new diseases came to the forest with the strangers.
The Yanomami people tried to save their forest, because it was their home. But the people who wanted gold were stronger.
Many forest people try to save their forests. Chico Mendes was famous in Brazil because he wanted to keep the forest for his people. “I want the Amazon forest to help all of us—forest people, Brazil, and all the Earth,” he said. A few months later, in December 1988, people who wanted to cut down the forest killed Chico Mendes.
In Borneo, people were cutting down the forest of the Penan people to sell the wood. The Penan people tried to save their rainforest. They made blodtades（障碍）across the roads into the forest In 1987, they closed fifteen roads for eight months. No one cut down any trees during that time.
In Panama, the Kuna people saved their forest. They made a forest park which tourists pay to visit.
The Gavioes people of Brazil use the forest, but they protect it as well. They find and sell the Brazil nuts (坚果) which grow on the forest trees.

HAVE you ever thought of being able to fly around the world in a few hours though it is about 40,000 kilometers? Now, maybe you can. Last Saturday, the American X-43A airplane made its first flight. It reached a speed of 8,000 kilometers an hour. This makes it the fastest plane in the world. X-43A is only three to four meters long, but it’s very heavy: it weighs 1,270 kilos.
HOW old can an insect be? 400 million years! Last Wednesday, scientists found the world’s oldest insect fossil(化石) in Britain. The fossil shows that the body of the insect was as big as a piece of rice and had wings(翅膀). In the past, people thought the earliest insect was 380 million years old.
THERE will be a new “star” in the sky soon. China plans to send a satellite(卫星) into space be September 2009. It will stay in space for one year. It will go around the moon and take pictures. It must be very expensive, right? That’s for sure －1.4 billion yuan!
YUAN Longping, the father of hybrid rice, won the World Food Prize on Monday. Yuan developed the world’s first popular and widely grown hybrid rice. Hybrid rice plants can make more rice than the ones people grew before.

Noise pollution is doing much harm to our health now．Noise is a kind of invisible(无形的)killer．More and more students enjoy listening to music very much．When they listen to MP3 players，they like to turn up the volume(音量)．While watching TV，they keep the volume up．But they haven’t realized that the noise is weakening(减弱)their hearing．In fact，the noise not only influences each member in the family，but also influences the neighbors．
Noise pollution is a source of misery to people in our society．If people are often disturbed by it，they may feel uncomfortable or sad．What’s worse，the noise can make people mad sometimes．If a worker works in a printing factory for too long，his hearing loss is much faster than a common person working in a quieter environment．So everybody must pay attention to noise pollution．

★Try to use less noisy equipment(设备)(e．g．washing machines)．
★Keep the volume of TV，radio and music as low as possible，especially late at night．
★If your dog barks when left alone，make sure to leave it with a friend．
★If you have a party，tell your neighbors in advance(提前)and keep the noise a little lower．
I think the local environment protecting department(部门)will take measures to control the noise levels．But it’s everybody’s duty to keep a quiet environment．
1．Why do people call noise a kind of invisible killer?
A．Because we can’t see it with our own eyes．
B．Because it’s harmful to our health，but people don’t realize it．

In most parts of the world，many students help their schools make less pollution．They join “environment clubs”．In an environment club，people work together to make our environment clean．
Here are some things students often do．
No-garbage（垃圾） lunches．How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again．Every week they will choose the classes that make the least garbage and report them to the whole school．
No --car day．On a no-car day，nobody comes to school in a car—not the students and not the teachers! Cars give pollution to our air，so remember：
Walk，jump，bike or run．Use your legs! It’s lots of fun．
Turn off the water! Did you know that some toilets can waste twenty to forty cubic（立方）meters of water an hour? In a year，that would fill a small river! In environment clubs，students mend those broken toilets．
We love our environment．Let’s work together to make it clean．

In recent years，the Earth has been getting warmer．Average temperatures have risen．Possibly this is natural，but probably we are causing it．Modern people use a lot of electricity and drive a lot of cars．This puts carbon dioxide（二氧化碳）into the air and helps to make the planet warmer．When we hear this news，we may smile．No one likes long，cold winters，but，unluckily，there are many bad points about a warmer Earth．
First，the ice at the Poles melts and becomes water．The result is that the sea level becomes higher．Low islands will disappear．Cities on the coast will be in danger from the sea．Will Tokyo，Bangkok，Hong Kong and Shanghai become like parts of Holland – lower than the sea? Possibly we will have to build walls to keep the water out．Typhoons will become even more dangerous and frightening．
Sadly，the second point is that storms will become bigger．Super-typhoons will be born in the Pacific and do great damage to East Asia．The same will happen to the Eastern United States．
As the weather changes，some places that now have rain will become dry．The farmers will not be able to grow plants．Maybe some dry places will become wet – we don’t know，but we will soon find out，and the change will cause many problems．There might be wars because of it．

April 22 is Earth Day. Everyone on earth should care about and protect the earth.
The earth has warmed by 1(华氏) over the past 100 year, but why and how ? well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own .But many scientists say that people are doing many things which make the earth warmer.
First，green house effect is a very important reason for the change of the earth .People give out too much energy into the air every year. It makes the earth warmer .Climate change is another important reason. Sometimes it becomes too hot and sometimes too cold. Sometimes there is too much rain and sometimes too little. The change of the climate makes the earth warmer .In turn, the warmth of the earth changes the climate, too.
When the earth becomes warmer, there may be more rain and a rise in sea level. It will affect the growth of plants, animals and people .On a pacific island ,100 people have to move to higher ground because the sea is rising. These people can no longer live on the coast. Before that , two islands without people went underwater in 1999. Scientists say that the sea can rise by nearly one metre by 2100.
People can affect the earth’s air ,land and water. As for us, we can do many things to protect the earth. For example, we can use fridges less. We can tell more people about protecting the earth.

Have you ever recycled? To recycle is to take rubbish and make it into something new. Recycling is good for our planet because it makes junk into something that we can use again. Recycling also helps to clean up the litter that makes our streets look dirty.
All kinds of things can be recycled. The most common materials like glass, plastic, paper, metals, cloth are all recyclable. Sometimes these products are broken down to make the same kinds of products(产品). An example of this type of recycling is using paper to make more paper. Garbage can also be broken down to make completely new items as well!
Some items, like glass, can be recycled forever! We can use glass items, then break them down and use them again and again. Aluminum(铝)cans are one of the most successful recycled metals. They can be recycled again and again and nearly 60% of all cans have been recycled.
The average family of four can produce nearly 2,000 pounds of garbage each year. As time goes on, we have fewer places to put all of this garbage in. Recycling is one way to limit（限制）the amount of garbage we need to put into the land.
The next time you toss a can or bottle into the garbage can, look to see if there is a recycling triangle on the label. It is the international sign for recycling. It means that the item you are going to throw in the dustbin could be recycled .

Have you ever stayed in a hotel? Most Chinese hotels often provide guests with things like disposable (一次性的) toothbrushes, toothpaste, shampoo and slippers. Many guests like the idea because they don't have to bring their own. But, if you travel to Beijing, remember to bring your own things. Starting from June, some hotels in Beijing will no longer provide guests with these disposables. They want to ask people to use less disposable things.
Many disposable things are made of plastic. People throw them away after only using them once. It is a waste of natural resources (资源) and is very bad for the environment. Do you know, one Chinese person makes as much as 400kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw away about 19,000 tons of plastic bags and 1,320 tons of plastic lunch bowls every year! Plastic can take between 100 and 400 years to break down. So the less plastic we throw out, the better. So, wherever you travel, bring your own things and use them again and again.
Back at home and school, you can also do something to make our world a better place. Try to do these things in your daily life: Use cloth shopping bags, not plastic ones. After using a plastic bag, wash it out and let it dry. Then you can use it over and over again. Do not use paper cups. At your school canteen（食堂）, use your own bowl and chopsticks instead of disposable ones.
