Science has told us so much about the moon that it is quite easy to form an idea of what it would be like to go there. It is certainly not a friendly place. As there is no air or water, there can be no life of any kind. Mile after mile there are only plains(平原) of dust with mountains around them. Above, the sun and stars shine in the black sky. If you step out of the mountains shadows, it will mean moving from terrible cold into great heat. The moon is also a very silent(安静的) world, for sound waves (声波)can only travel through air. But from the moon, you can see a friendly sight(景色). Our earth is shining more brightly than the stars. It looks like a large ball, coloured blue and green and brown.

“Millions of young people will lose their hearing in five years if they listen to MP3 or MP4 players at a too high voice every day,” scientists say recently.
Do you often listen to MP3 players at a too high voice? Are you frightened to hear this?
The sizes of MP3 players are very small, but small MP3 players make it easy to take hundreds of songs with you. So many young people carry them and listen to music every day. MP3 players are very popular among students. 
The scientists say teenagers should be far from high volume (音量), including mobile phones’ noise. A study says, “High volume and long listening time can cause hearing problems.” They think if young people listen at more than 89 decibels (分贝) every day, they will lose their hearing in five years. A scientist said, “So many young people often use personal music players and mobile phones at a high voice. I am afraid that they may be losing their hearing.
So let’s turn our MP3 players down!

【小题5】What’s the best title of this passage?

Now, are you changing your living habits to have a low carbon life? Here are some strategies (策略) for you.
Strategy One
●Each week, choose one day when you don’t eat meat. Meat takes up lots of energy because it takes a long time to produce. And animals must be fed on farmed plants, which could be used to feed many more people.
Strategy Two
●Only buy the amount of food you need. When you buy food, go local rather than imported (进口的), and get fresh vegetables instead of frozen.
Strategy Three
●Make sure you keep the things such as paper and plastic bottles separate (独立) so that they can be recycled. There are places where you can recycle batteries. Make sure you find them.
Strategy Four
●Take showers rather than baths and reduce your shower time by two minutes. This will save water and give you an extra two minutes in bed.
Strategy Five
●Buses and trains are better than cars, but walking or cycling is better still. It’s also better for your health and cheaper. It can even be quicker than sitting in a car at rush hours in a busy city. For long distances, coaches are better than trains.
Strategy Six
●Try to buy good, long-lasting products even though they may cost a little more. A small screen TV is better than a big screen. Keep your electronic products one year longer than you would usually have.
【小题1】What does the underline phrase “low carbon” in paragraph one mean?

In the 13^th century, the famous Indian traveller, Marco Polo, travelled a long way to China. He saw many wonderful things. One of the things he discovered was that Chinese used paper money. In western countries, people did not use paper money until the 15^th century. However, people in China began to use paper money in the 7^th century.
A Chinese man called Cai Lun invented paper almost 2,000 years ago. He made it from wood. He took the wood from trees and made it into paper. He then put these pieces of paper together and made them into a book.
Now paper still comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. If there are no trees, there will be no paper. Every day, people throw away about 2,800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting nearly 48,000 trees every day. Since it takes more than 10 years for a tree to grow, we must start using less paper now. If we don’t, we will not have enough time to grow more trees to take the place of those we use for paper.
So how can we save paper? We can use both sides of every piece of paper, especially when we are making notes. We can also use cotton handkerchiefs（手帕） and paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant does give us a paper bag, we can save it and refuse (拒绝) it later.
Everyone can help to save paper. If we all think carefully, we can help protect trees. But we should do it now, before it is too late.
【小题1】When he was in China, Marco Polo __________ .

Have you ever stayed in a hotel? Most Chinese hotels often provide guests(客人) 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 dining-room, use your own bowl and chopsticks instead of disposable ones.
To protect our environment and our home, it is very necessary and important for us to save natural resources.
(  ) 11. Why do many hotels provide guests with some disposable things?

Do you kow that animals have love for each other and their children just like us humans? Let me tell you some moving stories of great animal parents.
Several years ago a heavy rain hit a town and made the river go up. When the rain stopped, people found that a dog swam to an island in the river twice a day for two weeks. Why did she do so? Her four children were there. The mother swam there every day to feed her babies. This true story moved many people.
Another story is about chimpanzees(猩猩). A scientist named Jane Goodall spent 4 years living with chimpanzees in Africa. She found that chimpanzees also cared for those that were hurt or got lost. “It is not only humans who have duties, animals also do,” she said.
Two birds in Chengdu also showed their parental(父母的) love. Their baby was hurt and fell on the street in the center of the city. Cars were driving past but the brave parents rushed down to the road and took the little bird away with their claws(爪子).
【小题1】After the heavy rain, the mother dog swam to the island ________.

Can plants eat people? Probably not，but there are many plants that eat meat．Some of them are big．And they can eat small animals．One famous meat-eating plant is the Venus flytrap(捕蝇草)．
The Venus flytrap is a very strange plant．It grows in dry parts of the United States．Its leaves are like the pages of a book．They can open and close very quickly．Inside the leaves，there are three small hairs．If a fly touches one of the hairs，the leaf closes quickly．The fly cannot get out．In about half an hour，the leaf presses the fly until it is dead．Then，the plant covers the fly．Slowly，the plant eats the fly．
Why do plants do it? Most plants get what they need from the sun，the air，and the ground．In some places，the ground is very poor．It doesn’t have all these important things，
especially nitrogen(氮)．Animal meat has a lot of nitrogen， so some plants eat meat to get what they need．Let’s hope that some of the bigger plants don’t get the same idea !
【小题1】The Venus flytrap is a kind of_________．
