Screens(屏幕) are an important part of our life. When you talk about “screen time”, do you know the screens have an effect(影响) on you, especially on (you) eyes?
In fact, spending a lot of time (look) at a screen isn't good for you.
But if you have to use a computer for work, what can you do to stay (health)?
Many eye experts say you should follow the “20-20-20 rule”. This means taking a 20-second break every 20 minutes to look at something about 20 (foot) away—that’s about 6 metres. This gives your eyes a break and makes them shift(改变) their focus from the nearby screen to something farther away.
Make sure the screen is the right brightness too. A screen that’s too bright ______ too dark will make your eyes tired. The idea is to ______ (great) reduce the blue light. And to help this, some companies ______ (begin) to sell blue light glasses a few years ago and they worked.
Sitting a little away the screen is also good idea: you should sit at least 50 centimetres away. If you find you’re moving close to the screen and straining(过度使用) your eyes to see, you could try making the words on your screen (large).

Your school days should be some of the best and happiest days of your life. How can you get the most 1 them, and make sure you do not waste this excellent chance to learn? Here is some advice.
Be active at school. Never say that things are difficult or 2 (bore). You should be 3 (interest) in school life and different subjects. Take part in as many 4 (activity) as possible.
Put your hands up 5 (quick) in class. Go around the school with 6 big smile on your face. Study hard, and don't waste your time at school. Teachers cannot make everything enjoyable for you, so try to do it by 7 (you).
Keep fit. 8 you do not have breakfast, you will be thinking about food in class. If you go to bed late and do not have enough sleep, you will be sleepy in class. 9 (play) sport over one hour every day can keep your body strong. At weekends, get together with your friends or join some clubs in order to make your life colourful.
Face the problems bravely. Do not say that you will do the things tomorrow. If you fall behind, you will have problems catching up with others. You can't finish the race if you rest all the time. Everyone fails in some exams, loses some matches and has bad days. Don't let a small problem 10 (seem) very big or important. Don't forget to ask for help. You are young. No one thinks you must do everything quite well.
Follow the advice, and you will have a happy school life!
