There are many ways to help improve your health like eating healthy food, taking exercise and getting medical help. But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night. The general sleeping rule is that the younger you are, the longer sleep you need.

The problem with sleep is that more and more people in the world are not sleeping enough. According to the World Health Organization over half the people in the world may be sleep-deprived. Having less sleep not only makes people feel tired but also causes accidents. In the United States alone, sleepy drivers cause at least 100,000 traffic accidents a year. Also sleep problems can cause medical problems such as high blood pressure.

How do we teach these people to learn the value of sleep? Perhaps they may listen to the advice of Dr. James Maas an expert(专家)in sleep. He says, “Sleep is like a credit card(信用卡). When you sleep less. You are only borrowing time. You always have to pay it back. The more hours you don’t sleep, the more hours you should sleep to ‘pay back’ the hours on your ‘sleep credit card.’”

For those who value work more than sleep, they should listen to what a famous person once said. “Don’t think you will be doing less work because you sleep during the night. That is a foolish idea which is held by people who have no imagination. You will be able to do more.”

In order to prevent the spread of COVID-19. the Ministry of Education has decided to put off the start of the spring term for schools. To make sure that students could keep studying, most schools began to offer online courses for them at home. However, you may met all kinds of difficulties while taking online classes for the first time. I hope you can get some ideas from the following examples of four students who tried to improve their online studies.

Ensure a good connection

Zhao Yuchen, 13, Beijing

For me, the biggest headache about studying online is the poor quality of my Internet connection. This almost made me mad. During one of my online classes, I couldn't hear my English teacher's voice and I had to reconnect. It wasted lots of time. Since then, I checked my network before class every day, and I asked my family members not to use the Internet while I was having a class.

Plan your time properly

Lin Xiyu, 14, Shanghai

I had a hard time planning my course timetable at first. Planning ahead with a study calendar is very important for effective (有效的) online learning. Creating a study calendar will help you remember important dates like online exams or deadlines (最后期限) for your tasks. Making a to-do list is also useful. These are all good ways to help us learn better online.

No distractions (分心)

Zhang Penghui, 5, Heilongjiang

Online learning needs strong self-control and willpower (意志力). There are lots of distractions while studying at home.

My mom likes to offer me snacks and drinks, which sometimes distracts me from listening during my classes. I have asked her to stop entering my room while I'm studying. A quiet room and a clean desk can help me concentrate (聚精会神).

Focus on your studies

Wang Ruixue, 14, Hebei

The Internet is new to us children in the countryside. Many online games are very attractive to me, and they may take a lot of time away. I have used a timer (计时器) to record time spent on non-course websites and limit myself to five minutes at a time. When you feel yourself losing concentration, consider taking a short break, but make sure that the time you spend on your breaks won't take too much of your study.
