What is the sky? How high is it? What color is it? What birds can live above it? These questions are difficult to answer, aren't they? In fact, the sky has no color. Then why does the sky look blue?

    We know that there is air around the world. When planes fly, they need air to lift their wings. Planes can't fly very high. That is because the air gets thinner when they go higher. The same will happen to us if we go high enough. If we go up about 1,200 kilometers from the earth, we'll find no air there. Some birds can fly into the sky as high as a plane, but they cannot fly or live without air.

    Looking up above us, you will see the blue sky with white clouds. It is usually light blue. The color would be bluer when you see on the top of a high mountain. And you will see fewer clouds in the sky between you and the sun. Sometimes the sky doesn't look blue. When the sun rises and falls, you will see red, orange and other colors in the sky, such are the most beautiful moments of the day.

    Who can see the colors of the sky high above the earth? The astronauts! They can see those beautiful colors of the sky from the outer space. However, before flying into the outer space, they sit in a spaceship high above the earth and there is no air at all. The sky would be that dark and its color would be black.

    Now you may understand that we see colors because the air scatters (使散射) the sunlight. Light travels through the air. Without air there would be no colors.

My favourite animal

One year, a college in the Unites States announced that it would offer a lot of money for the pure white marigold(金盏花). The high reward attracted so many people, but in the nature, besides golden, the marigold is brown, and it is not easy to get the white one. So after they were excited for a time, many people had forgotten the announcement.

One normal day after 20 years, the college received a letter and 100 seeds of pure white marigold. It turned out to be anold woman of over 70 years old. Some experts in the college doubted it , but in order not to let her down, those seedsfinally took root(根) in the earth. The miracle appeared after one year: the field was covered by pure white marigold.

Therefore, the old woman who was always unknown to the public became a newfocus.

The old woman was a flower-lover. When she read the announcement 20 years ago, she got very excited like others. But her right children were totally against her decision. After all, a woman who never knew the seed genetics(遗传学)  couldn't complete what the experts could never do, so her thought was only a daydream.

Still, the old woman didn't change her mind and went on working. She planted some of the most common seeds and took good care of them. A year later, when the marigold came out, she chose one faintest(最暗淡的) from those golden and brown flowers and get the best seed. The next year, she again grew them and chose…. Day after day, year after year, through many seasons, the old woman's husband died, her children flew far and high, a lot of things happened in her life, but only the desire to grow the pure white marigold took root in her heart.

Finally, after 20 years on the day we all know, in the gardenshe saw a marigold which was not nearly white, but as white as sliver or snow.

A problem even experts couldn't deal with was solved by an old woman who didn't understand genetics. Wasn't it a miracle?

To take root in the heart, even the most common seed can grow into a miracle!

Reading Outside Class

As we all know, reading has a lot of advantages. 

……

Mrs. Brown will go to see her daughter in New York. She wants to take some of her favorite books. She finds an old-book in her bookcase. It's a book about art. Mrs. Brown finds a library card in it. "Oh, it's from the library," says Mrs. Brown. She finds the due date on the library card. The due date is November 20th, 1985, but it's 2023 now! "Oh, I must pay a fine (交付罚款) for it," thinks Mrs. Brown. She doesn't know what to do. She thinks about it. "I can just throw the book out (扔掉). No one will know," thinks Mrs. Brown. So she throws the book into the trash can (垃圾桶). "No, that's not the right thing to do," says Mrs. Brown. Then she takes the book out of the trash can.

" Am I an'I' person or an 'E' person?" It is a popular topic among young people around China today. Many people are crazy about it so that they take a personality test named MBTI to find out the answer.

Many people find the test useful. It groups people into 16 types, which start with the letter"I"or" E", such as" ENTJ" and"INFP"." E" is short for" Extroversion" while"I" is short for" Introversion". After testing, some say," I'm extroverted; I should go to parties and make friends," while others think," I'm introverted; I prefer working alone, and maybe I' ll be a writer someday." They believe knowing their type can help them make quicker choices about activities, careers, and life paths.

However, there are some problems with the test. Some get different results when they retake it, and some find it hard to answer certain questions. For example," I like watching TV alone, but I also enjoy hanging out with friends. Am I an'I' person or an'E' person?"

When you take a personality test, you may think," Oh, that's me." That's because the descriptions are generic. They can be used to describe many people. Research has found that over50% of people got a different score when they retook the MBTI test just five weeks later. Personalities can change with time, and they are not black- or- white, scientists say. You may be introverted now but become extroverted when you get older. Or, you can be both an"I" person and an"E" person. Don't label(贴标签) yourself! Studies have also shown that the test is not real at telling people's success in different jobs. So, don't take it too seriously.
