March 16 is World Sleep Day. This year’s slogan is “Breathe Easily, Sleep Well”. Its aim is to celebrate the *benefits of good and healthy sleep.
Fangfang, from Liaoning, just became a high school student last September. She gets up at 5:30 a.m. every day and goes to bed at about midnight. Fangfang feels sleepy all the time. “I want to finish all my homework first,” she said.
Sleep is like food for the brain. Enough sleep helps the body and brain grow and develop. According to the National Sleep *Foundation in the US, adults need seven to nine hours of sleep every night. For students who are 10 to 17 years old, a healthy amount is about eight to nine hours every night.
But many students don’t get enough sleep because of early school start time and heavy homework. About 80 percent of middle school students don’t get enough sleep, the China Youth and Children Research Center reported. For some students, they want to sleep early, but they keep worrying about their schoolwork and can’t fall asleep quickly. For others,they may even have insomnia, and usually they have to ask the doctors for help.
These sleeping problems greatly *affect people’s life. Some doctors found out that *lack of sleep for teenagers lead to poor grades. Students without enough sleep cannot pay attention in class or do well in sports. Also, they often become anxious easily.
Luckily, with good sleep habits, it is easier to fall asleep. Some of these good habits include *avoiding drinks that make people excited late in the day, going to sleep at the same time every night, and sleeping in a comfortable place that is dark, quiet, and neither too warm nor too cold.
More tips to get a good night’s sleep:
Exercising during the day. You’d better do sports three hours before going to bed.
Don’t eat big meals before bedtime. Drink a warm glass of milk.
If you stay awake worrying about things, try making a list of things that you need to do before you go to bed.

Have you ever wondered what goes through your mind when you choose where to sit in a new classroom? Or in a waiting room full of strangers? Or on a bus? Researchers have found out some interesting facts.
Perhaps unsurprisingly, we prefer to sit closer to people like ourselves. Girls sit by girls and boys sit by boys. Adults sit together and young people choose another young person to sit near. But it goes further than this. We even choose to sit near someone who looks like us. People with glasses are more likely to sit near other people with glasses. People with long hair sit closer to other people with long hair.
We seem to believe that people with similar habits or hobbies will share similar attitude and we are more likely to be accepted by people like ourselves or even, we think we may be safer with people who look like us. Sometimes that’s true but it's a pity if we always stick to the same people, the same group. The danger in always staying in our comfort zone (舒适区)is that we just recycle the same opinions, the same tastes and the same ideas. We lose the chance to learn something new, find out about interesting things, hear funny stories and discover difference.?
When we always stick to the same people, how can we ever break down the barriers which prevent us from getting to know people with different ideas? And how can we avoid the ignorance (无知),which too often leads to prejudice (偏见) and even fear? If instead you want to live in a society that opens to changes and new things and different opinions, be the cat among the pigeons.
Move out of your comfort zone. Go and sit next to someone different. And don't just sit there in silence. Say hello. Ask a question. Start a conversation. That’s how we make friends. That’s how we learn about people. That’s how we open our minds to new ideas. That's how we live an exciting life.
