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 interest in cooking started when I was 11， partly thanks to my mother． She didn't really like cooking and when she did cook， I didn't like her food． Once I was watching something about cooking on TV and I thought I could do this， so I went to the bookstore and looked for the biggest cookbook I could find．
During a year， I had produced most of its recipes（食谱）and was ready for a bigger challenge（挑战）． I wanted to create my own dishes and I started cooking for more people than just my family． To my joy， my parents allowed me to build a test kitchen． I did much cooking to test my dishes in itand my skill improved quickly． Later， my mom and I set up a dinner club that organized monthly events inside my home． Now as a teen chef （主厨）， I have also cooked in top﹣class restaurants around the country． I am not doing it for the money， but because I love cooking．
Now I know that when you stop caring whether you'll be famous or do well， your dream will come to you．

According to a 2018 study from San Francisco State University， nearly 2． 4 billion people around the world used a smartphone in 2017． By the end of 2019， more than a third of the global population will be using a smartphone．
However ， smartphone technology can be a double ﹣ edged sword ．On the one hand， it sends us unlimited amounts of information． On the other hand， using a smartphone may become an addiction．
Erik Peper and Richard Harvey are both health education professors at San Francisco State university． They led the study． Peper explains that smartphone addiction forms connections in the brain that are similar to drug addiction． And these connections form slowly over time． Also， addiction to social media may affect our emotional state． The two professors asked 135 university students about their habit of smartphone use and their feelings． They found that students who used their phones the most reported higher levels of feeling lonely， depressed and anxious．
Peper and Harvey do not blame users for their technology addiction． They believe it is the tech industry's desire to make more money that is to blame for the technology addiction． The researchers warm that workers in the technology industry know how to control our brains and turn us into addicts．
But the researchers say that we can limit our brains to be less addicted to our phones and computers． Erik Peper suggests timing off our phones before we sleep or do something important． The researchers also suggest taking control of when and where you answer texts or emails． You do not need to answer them all． And you certainly don't need to answer them as soon as you get them． They also suggest putting limits on the time you spend on social media．If you want to catch up with friends on Facebook，set aside a small amount of time to it．you should focus on important tasks and do not allow technology to disturb you．
