Are you short-sighted? If you are, your parents might have tried to do something to fix it, such as having you get an eye massage(按摩), take medicine or even get surgery(手术). People who offer these services or products often say that they can reduce or even cure short sight.

However, you will no longer see advertisements like this before long. The government has issued a notice to ban(禁止) businesses from using words like “recovery" or "short sight cure" in their advertisements.

The notice says that short sight cannot be completely cured with current medical technology. Therefore, these advertisements could mislead children and their parents.

Young people can prevent and control short sight by spending more time outside and less time in front of books or computers. People who have sight problems should first go to a hospital and let a doctor decide what to do.

More than 450 million Chinese have suffered from short sight since June 2018. Short sight rates are around 30 percent for primary school students, 60 percent for junior high school students and 80 percent for senior high school students. This is likely because students spend a lot of time reading books and using electronic devices.

To reduce short sight among young people, the government made a new plan last August. The plan is designed to limit the amount of time children spend playing video games, as well as limit the production of new video games.

    Timely and transparent(透明的) information is important when dealing with epidemics. In the fight against the novel coronavirus, China has impressed the world with its fast response(应对), transparency and close cooperation(合作) with the international society.

After the epidemic broke out in China at the end of Dec. 2019, the NHC immediately sent an expert team to Wuhan, the center of the outbreak, for a deep investigation(调查). On Jan. 8, the novel coronavirus was first identified(确认) as the cause of the epidemic. Three days later, China established a daily reporting system, updating the public every day. Both the central and local-level governments held daily news conference, giving detailed numbers of new cases, deaths, patients in serious condition and recoveries.

At the same time, China has been sharing relevant information with the whole world in a transparent and responsible manner. Soon after China worked out the genome sequence(基因序列) of the new virus, it gave the results to the WHO(世卫组织) so that other countries could use it to carry out research and develop medicine. China also provided WHO with a detailed paper about more than 44,000 confirmed cases, which offers “a better understanding about the age range of people affected, the severity(严重性) of the disease and the death rate,” said WHO director-general Tedros Adhanom Ghebreyesus.

Meanwhile, efforts and support from around the world are also being welcomed to fight the disease. At the moment, a WHO team is working in China to find more methods to better treat and prevent the disease.

“China has set a new standard for other countries to prevent and control the epidemic, while no other country has the scale(规模), speed, transparency and openness comparable(比得上的) to China,” said Margaret Chan, former director-genera of WHO.

How much sleep do we need? We are all different. Some people need only three hours of sleep a night. Others need ten hours of sleep a night.

About one in three Americans has a problem with sleep. Many of these people can not fall asleep. The name of this problem is insomnia.
