Going Green

Green is no longer just a color. It is a new way of thinking about the world and a way of living your life. It's catching on all over the world. More and more people decide to "go green" because they know that we only have one planet to live on. We won't be able to live on it much longer if we keep wasting energy, and destroying(破坏) our home with air, land, and water pollution.

"Green Living" means:

    Understanding that your choices affect(影响) not just you, but everybody everywhere.

    Understanding that your choices affect not just today, but the future.

Understanding that when we talk about "saving the planet" or "saving the environment," we are actually talking about saving ourselves!

You may be thinking: "Hey, I'm just one person, on a planet with billions. I can't really make a difference." Well, have you ever seen a group of people do "the wave(波浪)"? It always starts off with one or two people, jumping up and down like crazy. Soon thousands of people are joining in. "Going green" is just like that. It starts with small, simple actions. It can soon build into a wave that will change the whole planet and lead us all to healthier, happier lives.

    Many students have already shared with us their efforts to help the environment:

Gabrielle, 12, writes, "I have helped my community plant a garden and I ride my bike or skateboard to school."

Kaitlyn, 10, says, "Lots of paper towels are thrown away, so I use a reusable cloth towel to dry my hands instead."

"I always recycle(重复利用)" says Natalie, 13. "You can call me a recycler! I always look at the bottom of things. I want to see whether they have the little sign that tells you it can be recycled. So I almost recycle everything!"

Now it's your turn to think about how you can "go green". Make important choices and take actions to improve the environment right around you and the health of the whole world.

    Many wild animals, such as pandas, are in d{#blank#}1{#/blank#}. Often there is not e{#blank#}2{#/blank#} land or forests, so the animals do not have a safe place to live.

    There are only about 1,600 pandas in the wild today. Pandas do not have many babies, and baby pandas often d{#blank#}3{#/blank#}. The situation is getting more and more difficult. We need to p{#blank#}4{#/blank#} them.

    The government is s{#blank#}5{#/blank#} up nature parks and the pandas live in peace there.

    Only humans speak using words. But all kinds in the animal world can communicate in one way or another. Maybe you have heard about the way bees dance around to send messages to each other and the way dogs bark in different ways to give warnings, to be friendly or to be playful. But did you know about infrasonic communication used by elephants? This is how it works:

    Humans hear low sounds like thunder rumbling in the sky. But we don't hear sounds lower than this. However, animals such as elephants and hippos can hear much lower sounds than humans can. And what's more, they can make those low sounds as well, and they use them to communicate with each other. This is known as infrasound.

    The amazing thing about infrasound is that it travels over several kilometers. Higher-level sounds like the one people can hear, don't travel well through walls, leaves, trees and so on, which is why we can't hear sounds from more than 100 meters away. But infrasound is much stronger and things like grass and trees have no influence on it. Therefore, it can travel much further. Elephants can hear infrasonic calls from four kilometers away!

    There have been reports of people watching groups of elephants feeding or resting and then the elephants suddenly all stopped what they were doing for no reason at all. They obviously heard a warning call from a long way away, but the people didn't hear a sound. In places like a zoo or wildlife park where you can get nearer to animals, it is a bit easier to sense when infrasonic sounds are made. When you stand near mother elephants with their babies in a zoo, you may notice a slight rumbling in the air every few minutes—not loud or strong, but clearly noticed. This is infrasonic communication—the mother elephants “talking” to their babies.

Early to bed, early to rise, makes a man healthy, wealthy and wise.

This is an old English saying. Have you heard of it before? It means that we must go to bed early and get up early in morning. Then we shall be healthy. We shall also be rich (wealthy) and clever (wise).

This is true. The body must have enough sleep to be healthy. Children of young age should have ten hours' sleep every night. Children who do not have enough sleep cannot do their work very well. They will not be wise and they may not become wealthy!

The body also needs exercise. Walking, running, jumping, swimming and playing games are all exercise. Exercise keeps the body strong.

Exercise also helps the blood (血液) to move around inside the body. This is very important. Our blood takes food to all parts of our body. The head also needs blood. Exercise helps us to think better!

Watching short videos（视频）is becoming more and more popular among students, 1 they are easy to watch and kind of interesting. However, there are some 2 when they watch the videos. 

Some short videos are not for the young. They are just 3 making people laugh and sometimes not good for young people. Another problem is that kids are spending too much time watching the videos. The 4 time they spend watching such videos, the less time they will have for their studies and home lives. What will 5 to these children in the future if they don't study hard? Can they find a good job? It is said that if children watch short videos for an hour or two each day, slowly they would not 6 their schoolwork. At the same time, this can be bad for 7 eyes. 

So I 8 young people can stop spending too much time on short videos and take their school and home lives 9 . They can spend some time doing sports to keep 10 or listening to music to relax after finishing schoolwork. 

What topic do more than 13 million American kids like? Soccer! The Soccer Industry Council of America reported in 1999 that all those kids were playing organized soccer. Add adults into the number, and you come up with more than 18 million Americans playing soccer. {#blank#}1{#/blank#}

First, I think there's the international interest. {#blank#}2{#/blank#} The excitement must be catching. 

Another reason is that soccer takes less equipment (设备) than some other spoils. So it's not very costly for a kid to join a soccer team. 

{#blank#}3{#/blank#} Though accidents may happen, body touching usually isn't part of the game. Therefore, fewer injuries are caused. 

Soccer attracts both boys and girls. Though soccer was at first only a male sport ( just like all other sports), soccer has caught on with girls. {#blank#}4{#/blank#} Interest in the sport extends to whole families, so there are more players, more fans, more coaches, and so on. 

Finally, I think there is the running factor. {#blank#}5{#/blank#} Kids love it, and few parents can say no to it.
