There are some easy things you can do to protect(保护) the environment and the earth. Choose ideas from the list or come up with a few of your own.

●Plant flowers grass or trees.

●Whenever you visit a park or beach, take away what you bring there—-keep rubbish in a bag until you can put it in a dustbin.

●Turn off the lights, TV sets when you leave the room. This saves a lot of electricity.

    Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑战) a world famous scientist!
Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸碱指示剂). They want it to take the place of litmus (石蕊) paper.
    "We've learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."
    British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.
But when the kids did some experiments in class last winter, they saw that the litmus paper didn't turn very blue with base matter. It's hard to get a clear result.
    Will there be a better indicator than litmus paper? The three kids decided to try and find out!
How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨) leaves, flowers and stems (茎) to get the pigments (色素) from them.
    The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper!
    "It's our first scientific journey, Huang said, "But it makes me want to try harder."

"If you want to see a thing well, reach out and touch it!"
That may seem a strange thing to say. But touching things can help you to see them better.
Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music.
All children soon learn what "Don't touch!" means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things we might buy: food, clothes. To see something well, we have to touch it. The bottoms of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All feel different under your feet.
There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them!
Most museums are just for looking. But today some museums have some things to touch. Their signs say, "Do touch!"There you can feel everything on show.
If you want to see better, reach out and touch. Then you will really see!

     How do you remember the way to your house? Where do dreams come from? It is your brain (大脑) that does these things. A British scientist showed that “sleep can improve one's memory.” It's not a dream for students to study when they sleep. In fact, your brain is working day and night. If you learn words before bed, a certain part of the brain may help you to remember the words while you sleep. What's more, another scientist in the USA found that there was a “talent button (天才按钮)” in the human brain. It might make a person more talented.
    There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning (打哈欠) keeps our brains “cool”, which makes us think quicker.
     Here are some pieces of advice to keep a good brain:
     Eat healthy food.
     Get a lot of playtime or exercise.
     Don't drink or smoke.
     Use your brain a lot.

Chinese scientists called on all over the country to fight against serious water pollution in China yesterday.Following days of heavy haze(雾霾)that influenced most parts of China earlier this year polluted water is becoming another big worry among people on popular social Internet

Websites have called for cutting down water pollution in necessary ways.

“We should not only protect water,but also pay attention to water pollution,”said Xue Manzi,a well-known investor(投资人)on Sina Weibo.“Dead pigs are found in rivers and waster is poured into rivers and underground.”said Xue.The Huangpu River provider 22 percent of Shanghai's drinking water.But earlier this momth,thousands of dead pigs were found in it.This made people scared and worried,although local government tried to showthat the water was safe.

In February,some factories in Weifang in Shandong had put waste water underground,polluting the local drinking water.“Clean water and air are necessary for people to live. A responsible government will strictly protect the environment from being polluted,”said a microblogger.

Isn't it time for us to have a better thinking about our living environment?Do we want to kill ourselves by serious pollution? All the companies should have a serious sense of responsibility.The health of people is far more important than money!

How much do you know about air pollution? When people talk about air pollution, they usually think about outdoor air 1. But do you know that there is also 2 pollution inside homes, offices, hotels and other buildings? The air in your home can be 2 to 100 times more polluted than the air outdoors! In fact, some American doctors say that 50％ of illnesses have something to do with 3 indoor air.

A lot of pollution comes from 4 activities such as smoking and cooking. As most people 5 about 80％-90％of their time inside buildings, it is important to take indoor air pollution seriously too.

Air pollution influences our health in many ways. When the air is polluted, not only 6 children and old people suffer from it, but people with 7 problems suffer as well. Indoor air pollution can 8 people's eyes, noses and throats. Air pollution, both indoor and outdoor, can also lead to lung cancer and heart disease! In the Great Smog of London in 1952, 4,000 9 died in a few days because of the pollution! It is 10 that half a million young children and women die each year in India because of indoor air pollution!

Caterpillars (毛虫) are often used as fish bait (鱼饵). However, the creatures may get a better life — they are now setto join the war on plastic wastes.

Federica Bertocchini isa Spanish scientist. When she's not working in her lab, Bertocchini keeps bees.One day, when she looked at her hives(蜂箱), she found dozens of caterpillars called waxworms(蜡虫). These insects are often used to feed fish. In the wild, however,they live in beehives, feeding on the wax that bees use to build theirhoneycombs(蜂巢). Bertocchini picked out the caterpillarsand put them in a plastic bag. Surprisingly, when she returned to the bag aftercleaning out the hives, she found it full of holes. The worms had eaten theirway out.

Bertocchini came up withan interesting question: Were the waxworms digesting(消化) the plastic? Then she got in touch with peersat the University of Cambridge, Paolo Bombelli and Christopher Howe. Accordingto their paper in Current Biology, some chemical or combination of chemicalswithin the insects can really break down plastics.

Bertocchini and hercolleagues discovered that it took a waxworm about 12 hours to eat up amilligram of plastic shopping bag. However, the scientists warned that it wouldbe at least several years before they release(释放) waxworms into the environment. They want to know if the insectsare using the plastic as a food, or just because they want to escape. If theyjust want to escape, they are going to get fed up very soon. But if they'reusing it as an energy source, it's a completely different game. Anotherquestion lies in the insects' feces(粪便). If the fecesturn out to be poisonous, then there will be little point in pursuing(追究) the matter.

"It's certainly notgoing to be the case that within six months we've solved the world's plasticproblem," said Howe. "l wouldn't want people to think that within afew months, they can start throwing away plastic bags without worrying aboutit."
