For most Chinese people, rice is just an important part of almost every meal. 1for Yuan

Longping, rice was more than that. It was his life-long career(事业)。

Yuan, known as China's "Father of Hybrid Rice(杂交水稻之父)", created hybrid rice that helps2 the world. On May 22, Yuan died at 91. 3around the world were sad to hear of his passing.

In the 1960s, people in China didn't have 4 food to eat. Many people even died because of this. Yuan was5to see this. He decided to work on a kind of hybrid rice. He thought this rice could feed more people.

At the time, other scientists didn't think hybrid rice was6. But Yuan wanted to try anyway. He spent four years7 wild rice that could be crossed(杂交)with other plants. In 1964, he found it!

In 1973, he grew the world's first hybrid rice strain(品种). It could reach a yield of over 500 kg per mu, 8than the 300 kg yields of other kinds of rice. Farmers can grow it on many different kinds of land. It can fight bad 9and disease, too.

This kind of hybrid rice has been grown all over the 10 since then. It has helped China feed nearly one-fifth of the world's population with only about 7 percent of the world's farmland.

As we all face the novel coronavirus(新型冠状病毒), protecting yourself is the same as protecting others. Here are some safety suggestions based on the Handbook for the Prevention and Treatment of

COVID-19, which was released by WeDoctor Digital General Hospital.

Stay away from crowds and wear masks

If you have to go to crowded places, remember to mask up. Keep at least one meter of distance between yourself and other people, particularly those who are coughing or sneezing. Why? Most crowded places are poorly ventilated(通风的). The novel coronavirus can be transmited (传播)via mucus droplets(粘液飞沫)and travel one to two meters in the air before falling to the ground. The droplets can be transmitted farther by sneezing or coughing than by speaking. If you are too close, you can breathe in the virus. Wearing a mask can prevent droplets from reaching your face or mouth. _________▲_________

Keep proper indoor ventilation(通风) while at home. Open windows to let in fresh air during the day. It's best to do this three times a day for 15 minutes to half an hour each time. Why? The virus can only infect(感染) you when it builds up to a certain amount. Proper ventilation can stop the virus from gathering into a greater amount.

Keep up good habits

Keep healthy habits such as eating a balanced diet and exercising regularly, as well as getting enough sleep. Why? Doing these things can strengthen your immune system(免疫系统), making it less likely for you to become infected.

Wash hands properly

Remember to wash your hands before eating, after going to the bathroom, coming home, coming into contact with garbage and touching animals. Avoid touching your eyes, nose and mouth before washing your hands. Why? Your hands might touch surfaces that can be contaminated(污染) by the virus. Washing your hands frequently(频繁地) can stop the virus from entering your body.

Pollution inside homes and other buildings kills more than 4 million people each year.

Many people die as a result of breathing smoke or from cooking over wood-powered of coal-powered stoves(炉子）.

One way to reduce the number of deaths is through cooking equipment powered by the sun.

Crosby Menzies, a solar power(太阳能)expert in a South African company, described his latestsolar cooker(厨灶)called the"Sol-4". "It is four square meters of mirrors, six to eight meters in length. It isquite a large cooker. "

The "Sol-4" works by reflecting(反射)light from the sun off large mirrors. The mirrors direct(把…对准)the light at a cooking pan. Then the light heats the pan with solar energy. Within two minutes, the pan is hot enough to cook sausages and onions. In just four minutes, water can be boiled. That is as fast as cooking with natural gas or electricity.

The cooker is also much "friendlier" than other models because people do not have to stand in the sun to use it. And people can prepare meals without having to collect firewood or spend money on coal. Such individuals would be less likely to have breathing illnesses from harmful smoke.

At present, the cooker only works when the sun is shining. But engineers are working on a way to make it work without sunlight.

Each cooker costs about $2, 000, which is a large amount of money for most Africans. To deal with that problem, Crosby Menzies has crated a non-governmental (非政府的，非官方的) organization called Solar Cookers for Africa. It plans to raise money through donations(捐赠) to provide poor people with solar cooking equipment.

There are some easy things you can do to protect the environment and the earth.  Choose ideas from the list or come up with a few of your own.

● Plant flowers, grass or trees.

●Whenever you visit a park or beach, take away what you bring there—keep rubbish in a bag until you can put it in a dustbin.

●Turn off the lights and TV sets when you leave the room. This can save a lot of electricity.

●Turn off the tap when you brush your teeth. You can save some water by not letting it run. Also, use a glass cup instead of a paper cup because this saves paper.

●Keep the doors and windows closed in winter to keep warm air in.

●Give your old books and magazines to a library instead of throwing them away.

●Give your old clothes to poor children you know instead of throwing them away.

●Use both sides of paper.

●Stop pouring dirty water into the rivers or lakes nearby.

●Encourage all your friends to do the same things you do to help protect the earth.

You don't have to wait until Earth Day to do these things. Make every day Earth Day. If everyone makes a contribution to protecting the environment, the world will become much more beautiful.

Wang Fengqin, a 61-year-old woman in Beijing, volunteers to sort(分类)rubbish in her livingarea in Beijing Chaoyang District.

At 6: 30 every morning, while half of Beijing is still in sleeping dreams in bed or enjoying a delicious breakfast, Wang rushes through her busiest hours in the day. She gets up, gives her face a quick wash, takes a simple breakfast and rushes to the four rubbish dustbins beside the gate of her living area. There she checks the waste left by her neighbours to make sure it is sorted correctly.

"Sorting rubbish will improve the environment for all of us and it only takes a minute," Wang said. "I want to help my neighbours develop good habits."

As Wang spoke, an old man came by and threw a plastic bag full of rubbish into the dust-bin marked "recyclable".

"Hey, please there are some orange peels(皮)and fish bones in your bag, so they are supposed to be put into the dustbin marked ' kitchen waste ', " Wang told him.

Learning the old man was in a hurry, Wang let him go, opened the bag herself, picked out the kitchen waste and threw it in the right dustbin.

Wang has been doing this every day from 7∶30 a. m. to 9 a. m. and from 6 p. m. to 8 p. m. since March 10. She says people usually go downstairs and throw out rubbish at this time.

"Most people had no idea about sorting rubbish at first, but now 90 percent can put rubbish in the correct dustbin," Wang says. However, she plans to keep doing this job until all her neighbours sort correctly.

In China, three- child policy has come out. That is to say, all couples are allowed to have up to three children.

A Chinese Communist Party statement gave a number of reasons for the change in policy. The statement said the change is meant to balance(平衡)population development. It said the move also tries to stop a declining(下降的)birth rate and strengthen the country's work force.

China's annual number of newborns has fallen for four years to around 12 million in 2020, according to the National Bureau of Statistics.

The declining birthrate has also brought a sharp increase in the proportion of the population aged 60 or above, rising from 10. 3 percent to 18. 7 percent in the past decade(十年). The population of those 14 or younger dropped from about 23 percent to 18 percent during the same period.

China—the world's most populous country launched the one-child policy in 1980. It began relaxing its decades long family planning policy for urban couples in 2002 and carried out the two-child policy in 2016.

"After the second-child policy took effect, a large number of families wanted to have a second child but feared the difficulty in child-rearing(养育子女), " the National Health Commission said. Therefore, to carry out the three-child policy, China has planned to take some support measures to lower fertility and child-raising costs. Projects in the short term include setting up public community centers in 150 cities and adding 500, 000 public nursery care slots.

Huang Kuangshi, a researcher at the China Population and Development Research Center, said:

"The new policy will cater to(迎合)the demand of most couples to have more children, so the three-child policy is likely to remain for a relatively long time."

We often believe our parents are always there for us, but this is not true for "left-behind" children. They can see their parents usually once a year. Parents have to ask the to look after the young, leave them behind in the countryside, and go to big cities to work.

In China, there are about 21 million children from the countryside, and one third of them are left behind. At the end of each year, these parents will gohome to stay with their kids for a few days.

In fact, these children will have manywith schoolwork and health. For example, the old may not be able to help them with homework or look after them well. This will make these children lose parents' love and keep themselves away  other people.

The government(政府)is now trying their best to take good care of the left-behind children, such as sending volunteers to the countryside. They will report to the government they find something wrong with any left-behind child. However, the best way to solve the problems is to bring parents and children back together. The government tried to ask these parents to go back to hometowns to for work and business. way is to make it easier for the children to go to school in big cities. Then their parents can both work and see them every day.

Many governments showed great improvement in  the problems. Thanks to them, the number of left-behind children has decreased by (减少了) 22. 7 percent according to the latest report.
