The novel coronavirus pneumonia (新型冠状病毒肺炎) broke out in Wuhan in 2019, Hubei province in December 2019. Later, it spread to other parts of China. Many people got ill. This year the city was locked down from January to April to prevent the virus from spreading further to other places.

The city built two hospitals for the people with the novel coronavirus. They are Leishenshan Hospital and Huoshenshan Hospital. Builders worked hours a day and they worked very fast. They built the hospitals in two weeks. The two hospitals have a big capacity (容量) and one of them has room for 1,600 beds.

More than 120,000 people, including engineers, construction workers, volunteers, and over 30,000 medical workers, came to help the city. They worked without breaks.

In China, each year we produce about 150 million tons of city waste according to a report. Where does the waste go? People usually burn or bury (埋) it. We also receive waste from some developed countries. We get useful materials from it. What about the useless part? Still burned or buried. But is it a proper way?

Waste pollutes the environment, harms people’s health and causes animals to die. It also gets in the way of green and sustainable development. We can’t make money at the cost of the environment. We should leave clean water and green mountains to our next generations (一代，一辈).

China is getting really serious about waste now.

We are taking less waste from developed countries. From January 2018, China started to stop 24 kinds of waste coming into our country. And more laws and rules about dealing with waste have been made. Anyone who breaks the law will be punished.

China also tries to put waste into good use. One example is the waste electricity factories. They burn waste to make electricity in a green way. No harmful gases or water will get into the environment.

The Chinese government is encouraging people to do waste sorting (分类). Cities like Shanghai, Chongqing and Beijing have their own sorting systems. More will join them soon. More and more people are forming the habit of separating their waste.

Remember when you were a little child trying to learn to walk?

First, you had to learn how to balance yourself and stand.     41     You laughed sometimes and cried at other times. After much practice, you finally learned how to balance yourself.     42     You’d stand everywhere you could. It was a happy time—you did it!

Now the next step—walking.     43     It didn’t look that hard—just move your legs while you were standing. Wrong—more difficult than you ever imagined. But after you tried again and again and again, you understood how to walk.

If people found you walking, they cheered, “Oh, look at what the kid is doing.”     44     But look back on those days when you were the little child. how many times did you try when no one was watching, or when no one was cheering? You couldn’t wait for someone to encourage you to take the next steps.     45     So, keep trying and encouraging yourself if you want to succeed in doing something.
