You may think that light pollution isn't something extraordinarily important. You may believe that every other type of pollution has a larger impact on the environment that light pollution does. But light pollution is serious.

    Light pollution, or “sky glow”, is the glow you can see at night above cities and towns. Light pollution is a problem that has been accompanying man ever since he started his first fire some 15,000 years ago. Light pollution is the light that comes from streetlights, buildings, parking lots and any other source of light that is reflected or directed into the atmosphere.

    Urban light pollution means that one-fifth of the world's population can no longer see the Milky Way(银河) with the naked eye(肉眼). Many city kids, even if they did look through the orange smog above their heads, would probably see only a handful of stars. We have lost our view of the stars, and we have mucked up our  night-time environment as well. Astronomers are calling for the dark places on Earth to be preserved as national parks.

    Lots of people find the ever-brightening night annoying, and animals that are programmed to prefer the dark may avoid a brightened habitat. Sea turtles can get lost searching for a beach to lay eggs, and their hatchlings(孵化的幼仔)may confuse over-lit beachfront resorts(度假胜地) for the ocean horizon, wasting precious energy needed to find the sea and escape predators(食肉动物). Because their necks aren't yet long enough to see things far away, baby turtles rely on the mirror image of the moon to guide them to the sea, to begin their new life. A car may even hit a particular turtle, which was thinking the light from a nearby city was moonlight reflecting off the ocean waves. Birds that live in and around cities can die because of sky glow, too. The bright lights can blind them, leading to countless collisions with buildings and other tall structures.

    On an individual level, people can help reduce much sky glow by using lighting only when necessary. The stars above us are priceless heritage— for not only for astronomers but for all humans. More of our children should be able to look up at night and see the Milk Way.

Dear Editor,

I'm the boy student in a key middle school in our city. I fond of play the piano. It is known by us that the college entrance examination is approaching. I must get good prepared for it. So I have only fifteen minutes to play the piano on every day. I don't want to give up my favorite, and my parents forbade me to continue playing it. They think it a waste of time to do it now. How do you think of it? Could you give me some advices on how to deal with the problem? I am looking forward to your early reply.

Thank you.

John

    I was from Detroit in the United States. During his senior year in high school I win a scholarship to study singing in London. I went there in summer, and I stayed with someone's home. People there were very sweetly, and it was a really fun summer. I got the inside view of that it's like to live there. I loved it but one thing that surprising me was that people had to go to such many different stores to do their shopping. There was also a lot of differences in language. They said things like “ring you up” instead of “give you a call.” It took me a little while figure out these differences. So it was fun.

I was so excited to get a match so soon.” He says. “6 I learned the boy was only born in 2008, I was silent. And I 7 I made the right decision. I must help him.”

    Some people 8 stem cell transplants to treat cancer. They must 9a donor with nearly the same genes(基因). It means the matched 10 must have the very similar gene. The possibility of the long-distance match between Jiang Yongfeng and the little boy is 11. It sounds like a 12miracle（奇迹）. “ The little boy receiving Jiang's donation is very 13, ” doctors said.

    Some donors were 14 to donate stem cells in out-dated ways because of poor health care systems years ago. It was a(n) 15 experience that many people couldn't stand. 16, Mr. Jiang was able to use a simpler and safer method.

    Usually donors and receivers do not meet, nor do they know each other's 17. Does Jiang Yongfeng mind that he doesn't even know the little boy's name? “ No,” he shakes his 18. “ I just want the operation to be done as soon as possible so that they can send my 19 to the UK and help the little kid 20 as soon as possible. I hope he can be brave and strong and that he can live a good life.

    I often read of incidents of misunderstanding or conflict. I'm left 1 .Why do these people create mistrust and problems, especially with those from other 2 ?

    I was growing up in Kuala Lumpur in the early 1960s, 3 children from different races and religions played and studied 4  in harmony. At that time my family lived a stone's 5 from Ismail's. And no one was bothered that Ismail was a Malay Muslim and I was an Indian Hindu-we just 6 our differences. Perhaps, our elders had not filled our heads with unnecessary advice, well 7 or otherwise.

    We were nine when we became friends. During the school holidays, we'd 8 the countryside on our bicycles, hoping to 9 the unexpected. At times Ismail would accompany my family as we made a rare shopping trip to town. We would be glad of his 10.

    When I was twelve, my family moved to Johor. Ismail's family later returned to their village, and I 11 touch with him.

    One spring afternoon in 1983, I stopped a taxi in Kuala Lumpur. I 12 my destination. The driver acknowledged my 13 but did not move off. Instead, he looked 14 at me. “Raddar?”he said, using my childhood nickname(绰号). I was astonished at being so 15 addressed(称呼). Unexpectedly! It was Ismail! Even after two 16 we still recognized each other. Grasping his shoulder, I felt a true affection, something 17to describe.

    If we can allow our children to be 18 without prejudice, they'll build friendships with people, regardless of race or religion, who will be 19 their side through thick and thin. On such friendships are societies build and20 we can truly be, as William Shakespeare once wrote, “we happy few, we band of brothers”.

    When I was about 12, I had an enemy. A girl liked to point out my1. Week by week her 2grew: I was very thin; I wasn't a good student; I talked too much; I was too 3 , always feeling superior to others, and so on. I tried to hear all these as long as I could. 4, I became very angry. I ran to my father with5 in my eyes.

    He listened to me 6, and then he asked, "" Are the things she says true or not? Janet, didn't you ever 7what you're really like? Well, you now have that girl's 8. Go and 9 a list of everything she said and mark the points that are 10. Pay no attention to the other things she said. "

I did 11 he told me. To my great 12, I discovered that about half the things were true. I couldn't 13some of them, but a good number I could — and suddenly I wanted to change. For the first time I had a fairly 14picture of myself.

    I brought the list back to Daddy. He 15 to take it." That's just for you, "he said. "You know the truth about yourself 16 than anyone else. But you have to learn to 17, not just close your ears in 18, feeling hurt when something said about you is true, and you'll find it of help to you. Our world is full of people who think they know your affairs. Don't 19 your ears. Listen to them all, but hear the truth and do what you know is the right thing to do."

    Daddy's advice has always 20me at many important moments. In my life, I've never had a better piece of advice.
