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．

Dear Fang,
How are you these days? I have been in England for two months. It’s not a long time for a newcomer, and there are still a lot of things to do. Sorry for not being able to write to you soon.
London is an old but beautiful city. There are lots of places of interest to visit. Last weekend I went along Thames River with some friends from Japan, Korea and some other countries. The modern skyscrapers(摩天大楼) among the old buildings impressed(给…留下印象) us deeply. The classes started two weeks after I arrived here alone. Besides the language, I’m trying to learn about the culture as well. British people are quite different from the Chinese. Do you know the people here do not shake hands as much as we do in China? And it’s never a good habit to make noise when you eat. They think it’s impolite.
There is so much to say, but I have to stop.
I will write to you soon again.
Love,
