   The winter of 2019 seemed longer and colder than that in any other year because of COVID-19（新冠肺炎）. By Thursday, March 5th, 2020, over 30,000 medical workers have gone to Wuhan. They were fighting in a special “war”. Not only the patients but also the doctors and nurses faced the risk of life.

One of them is Dong Jie, a doctor. He did a good job during the 2003 SARS, so he went to this new war. He said he could share his experience in SARS with the doctors and give them confidence. He often showed the medical workers how to wear special clothes properly and better protect themselves. He also taught them how to treat patients.

In order to prevent the illness from spreading, all the public services must be closed. There were three special barbers with masks （口罩） in Hefei. They have helped hundreds of people cut hair since February 15th. They were busy visiting different places in the city as well as the countryside and offering free service from 2 p.m. till evening every day.

Zheng Wenyu and Ye Qiangiu are students. They tried their best to call on everyone to raise money for Wuhan. Many teenagers gave away their pocket money and lucky money. They raised about 120,000 yuan after two days. They used it to buy 60 tons of vegetables from local farmers and sent them to Wuhan.

All the Internet people called them heroes and they set a good example.

   Mobile phone used among school kids has become a problem for the school years, so one of the rules in our country says that school kids are not allowed to bring mobile phones to school.

It is a good rule because it is hard for school kids to resist the temptation（诱惑）of mobile phones. Mobile phone was a distraction（分心事）to students during school hours and it also brought teachers so much trouble in class before. Sometimes students might use mobile phones to cheat during exams.

However, some parents feel unhappy because they can’t get in touch with their children. Many people say that they understand why these parents would want their children to have phones, but all of them think schools should let the students know when they can use their mobile phones. So in lots of schools, if a student needs to bring a phone to school, his or her parents will have to write a statement and make sure that the phone is turned off during class. If the student breaks the rule and uses his or her phone during class, the student will be warned.

This is a reasonable rule, isn’t it? Under such a rule, students still have some freedom, and they learn how to improve self-discipline（自律能力）and live with new technologies. So rules do not necessarily mean there will be no freedom. In my opinion, freedom is based on good rules, so students should obey school rules.

   Have you ever heard of satellites（卫星）? What are they used for?

Satellites are helping to forecast（预报）the weather now. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere, where the weather forms. They send these pictures to the weather stations. So meteorologists（气象学家）can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change so that it can work better for people.

Nowadays, more and more countries have weather satellites. Nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive the new pictures, the meteorologists compare them with the earlier ones. Perhaps they may find the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say the weather will change soon. So the weather satellites are a great help to the meteorologists. Before satellites were invented, the meteorologists could only forecast the weather for about 24 or 48 hours. Now they can make good forecasts for about two weeks. Soon they may be able to forecast the weather for more than two weeks or more ahead.

With the development of the society, weather satellites will work better and better in people’s life.
