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．

The seed vault（种子地窖）

A lot of countries need different kinds of seeds so that they can plant them again． There is an important reason for this， Sometimes plants can't grow in a country because of bad weather or disease， so farmers need new seeds．

You can keep seeds in a "seed vault"． It's a place at a special temperature． The seeds don't grow，but they can live for a long time． Norway has the biggest seed vault in the world ﹣the Svalbard Global Seed Vault﹣and it has seeds from a lot of different countries．

The vault is on the island of Spitsbergen． The island is about one thousand kilometers from the North Pole． It's a very cold place so it's good for seeds． Above the ground， the doorway is small， but inside， the building is huge． You walk down a long corridor （走廊）， which is one hundred and thirty meters inside a mountain．At the end of it， there are three large areas with seeds．

There are about half a million kinds of seeds inside the vault． For example， there are kinds of seeds for rice from Asia and Africa， 32 kinds of seeds for potatoes from Ireland and seeds for different tomatoes from the USA．

The seed vault has space for a lot more seeds． You can put about 2.2 billion（十亿）seeds inside． The seeds can live here for thousands of years because of the cold temperature of ﹣18℃． So in the future， humans can grow any seed they want． In other words， the seed vault is the difference between life and death．
