On May 22, 2021, the whole nation was saddened by the news that Chinese scientist Yuan Longping died.
Dr Yuan Longping worked most of his life growing better rice. As a result of his research, the Chinese people are no longer worried about getting starved. His great work also helped the world produce more and more rice.
Yuan, born on Sept. 7, 1930. After graduating (毕业.) from Southwest Agriculture College, he worked as a teacher at an agriculture school in Hunan.
Several natural disasters (天灾) hit China in the 1960s. Yuan, saw many people die of hunger every day. Since then, he has researched how to grow much better crops.
In 1964 , he happened to find a natural hybrid rice (杂交水稻) plant that had great advantages over others. Yuan was excited about his discovery. He then began to study the parts of this unusual plant.
In 1973, he started to develop a type of hybrid rice species (种类) . It produced 20% more rice per unit than common ones. The seeding (种植) was very successful in the following year. This progress made China the world's leader in rice production.
More than 50% of China's total rice fields grow Yuan's hybrid species. People call him the "Father of Hybrid Rice".
Yuan once said he had two dreams — to "enjoy the cool under the rice crops taller than men" and that hybrid rice could be grown all over the world to help solve the food problem of the whole world.
A myth(传说) is something that is not correct, but many people believe. There are a lot of myths about the human brain. One of the biggest myths is that we only use 10 percent of our brains. The next part of the myth is that if we can learn to use the rest of our brains, we'll be much smarter. People say this all the time, but it's not true! Tho truth is that although we don't know everything about the human brain, we know that each part of it has an important function(功能). Modern scientists think the"10 percent myth" ridiculous(荒谬的). The other most popular myth is about being" right brained" or" left brained". According to this myth, people who use the right side of their brains are more artistic and creative. People who use the left side of their brains are better at math and science. This is as popular as the 10 percent myth, and it's also wrong. In 2013, a study at an American university examined the right brain and left brain myth. According to the study, we use both sides of our brains equally. It's true that we use different parts of our brains for different things. We use our left side for language more, and our right side when we need to pay attention. But there is no evidence (证据) that creative people use the right side more, or that scientific people use the left side more. We've talked about myths, so let's look at a few interesting facts about the brain. First of all, the brain feels no pain. Second, about 75 percent of the brain is made of water. It's also the fattest organ(器官) in your body. Here's one more interesting fact about the brain. Around the time you turn 18 years old, it stops growing. |
