On May 22, China's "father of hybrid rice" Yuan Longping died at 91. People in China and around the world felt1. Yuan was devoted to creating hybrid rice, which 2hunger of millions of people not only in China, but around the world.
3Yuan's graduation in college, he worked as a teacher at an agriculture school in Hunan. After seeing many people die of hunger during a serious famine(饥荒) that lasted from 1959 to 1961,he felt 4it. Then he decided to study hybrid rice 5. Back then, people thought 6 couldn't be crossed with other plants. But Yuan didn't believe this and 7 face the challenge. In 1973, he succeeded in growing the world's first high-yield of over 500 kg per mu, 8 than the 300-kg yields from normal rice. In 2020, hybrid rice developed by Yuan's team achieved a yield of 22. 5 tons per hectare in two growing seasons. Later, his 9 also started to research growing salt-tolerant rice, which is known as seawater rice.
Yuan once said he had two 10. One was to enjoy the shade under rice crops that were taller than men. The other was that hybrid rice would be grown all over the world. One day his dreams might come true!
Last weekend, I took Lucy to a park, where she discovered a track with large bumps (凸块) and sharp turns. At first, I thought Lucy was able to ride her bike along the track, but she quickly found that her bike was too low to the ground and kept getting stuck on top of the bumps.
Lucy looked at me with fear because she was still a biking newbie. I tried to encourage her, too, but really, I was thinking — this is going to be a disaster. Not because I thought she would get hurt. More because I thought she wouldn't be able to pick up enough speed to balance, then get really discouraged, and give up quickly. I imagined her throwing her bicycle to the ground and then crying all the way home.
But I was only half right. Lucy did have a lot of trouble riding the bike. She couldn't find her balance. She fell many times. At one point, she almost started crying because other younger kids were getting angry that she was slowing everyone else down. But she did not give up. She kept picking herself up and trying again. She even took the bike off the track and into the main park to practise pushing off and picking up speed on a flat ground. When she felt more confident, she came back. Then she did it over and over again until she finally reached her goal of going around the whole track without falling once. Then she didn't want to leave and everyone was cheering her on.
This was not a day that ended in a disaster. It was a day when Lucy learnt that perseverance (坚持不懈) pays off.
a. Lucy fell and got up lots of times.
b. Lucy picked up speed on a flat ground.
c. Lucy found her bike was too low for the bumps.
d. Lucy rode her bike around the whole track without falling once.
As children patients sometimes require long hospital stays, they often miss school or have little communication with their friends. This can lead to a sense of loneliness. That's why the global nonprofit(不盈利的) organization, TEACH, which stands for Together Educating All Children in Hospitals, has appeared.
For the past seven years, students from 15 universities have volunteered in about 30 hospitals worldwide to bring an educational program to sick children, which helps develop their interest in science and nature. And most importantly, they have raised the spirits and improved the confidence of thousands of sick children.
Isaac Snyder, TEACH Executive Director, said that it's heartwarming to watch the older students help the younger patients with some of the more advanced activities, such as engineering experiments. Unlike other programs, the program of TEACH makes children experience more than just reading coloring books, watching movies or playing online games. It teaches kids how science can be used for their own illness. Besides inspiring kids to see science in a new light, it helps kids understand the diseases that are putting them in the hospital. "It has a great effect on kids. And it can reduce their fears and help them have a positive attitude towards science," Isaac explained.
Isaac knows TEACH can also inspire volunteers to start a career in medicine. Take Isaac as an example. Though Isaac started out as just a volunteer, he finally studied medicine and made a difference to the lives of children patients. When people asked Isaac what he had seen in the patients' spirits as those patients joined in the program of TEACH, he shared, "The parents told the volunteers that this was the first time their children had smiled in days, and they were so happy. "
When we hear the word "virus", we naturally think of something dangerous. However, some viruses coexist (共 ) with us and we can even make good use of some of them, according to recent studies.
Biologists suggest that 380 trillion viruses are living on and within your body right now. These viruses are collectively known as the human virome (病毒组). Some can cause illness, but many simply coexist with you.
It appears that our viromes begin to accumulate when we are born. Studies have shown different viruses in the babies' bodies shortly after birth, suggesting that they probably come from the babies' mothers. The viromes grow in number as the kids grow up. They are not likely to change during adulthood.
"The virome looks like a partner that can influence our daily lives positively as well as negatively. We could even use the virome to improve our own health," said David Pride, an expert from the US.
One way is to use parts of viruses to cure diseases. Researchers in the US have got a chemical from a virus that kills bacteria (细菌) found in patients.
The other way is to develop viruses' value. Many viruses in our viromes infect bacteria. When the viruses move around the body, some arrive at the surfaces of our bodies such as the nose, throat and stomach. Viruses cannot divide and produce exact copies of themselves there, but they can wait for a bacteria to arrive. This process makes it possible to prevent us from getting certain diseases.

Last Monday I went to West Hollywood for a business trip. Upon my arrival, I looked somewhere to park my car and then found a new parking garage there.

I was doubtful, so I did not leave (immediate). I watched there. Soon a machine came, which lifted my car and transport (运送) it somewhere in the parking garage. When
I (return) later that day, the robot found my car, got it back and returned it to me. After I came back from West Hollywood, I searched about the parking garage online and learned better about it.
