Will it matter if you don't take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfast, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effort than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains. If a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention in class. Contrary to what many people believe , people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce other meals.

    Can you imagine the world full of crying and shouting, covered in darkness? However, it's not just a joke. It's a real  (describe) of a world without happiness and laughter.

    If you compare our life to a pie, what would you put in if you were in charge of making the pie? (obvious), many people would add as much happiness as possible. Do you know why? It's  happiness stands for sweetness in most people's minds.

    Don't think of it just as a comparison. Happiness is a flower  (live) in the sunshine, and it is not difficult to reach for it. We have a variety of  (emotion) like sadness, anger, fear, enthusiasm and happiness, and they all appear naturally when something (affect) our feelings. So, if we can change our attitude things in the world, we can certainly adjust our emotions. It means that we can choose to be happy if we want to, as long as we view everything in  positive way.

    If we can be happy, why not (choice) to be? Let's try together to create a world (fill) with smiling faces and sunshine.

Things You Should Know About COVID-19

COVID-19, a cousin of the SARS virus, has infected more than ten million people since the outbreak began in Wuhan, China in December, 2019. Scientists think it likely started in an animal and spread to humans. The World Health Organization offered guidance to countries on how they can prepare for it. Here are four things you should know about it.

What are the symptoms?

It's from a family called the corona viruses. The symptoms of this illness are pretty ordinary on the face of it: it's a dry cough fever and then breathing problems. But we also know about the more severe cases, which is where people have gone on to develop viral pneumonia（病毒性肺炎）, and those people obviously end up in hospital, and all the deaths have been among those people.

How is this virus transmitted?

It was hoped at first actually that it just came from animals as all corona viruses do. But now it looks as though it is actually passed from one human being to another. We've got people to people transmission, because the market has been closed for sometime, and there are cases in people who've never been near it.

So there actually isn't any treatment at the moment at all, because this is a virus. Antibiotics（抗生素）won't work. So really you want to know antiviral treatment, but none of the flu drugs that we've got works effectively on this now. A corona virus is different from a flu virus, so there actually isn't any treatment at the moment at all.

Should we be panic about this outbreak?

Though there have been so many cases so far, it is possible for us to largely reduce the risk of infection if we can take preventive measures, including regularly washing our hands, covering our sneezes, and wiping down surfaces. Good news is that in the months since, we've seen the social distancing measures taking effect, too.
