Salt in the soil has always made it impossible to grow crops.But that's now changing.
Famous agriculturalist （农学家）Yuan Longping said they would grow a special rice.They would turn 100 million mu of saline﹣alkali （盐碱的）land into farmland in the country over the next 10 years.
In 2017，Yuan's team successfully grew rice on the saline﹣alkali land in Jiangsu Province.It is called sea rice.Now they have made great progress.Both China and many other countries around the world have large saline﹣alkali land.If all of it can be used to grow rice and grain，it is very important for food security（安全）.And it will help the UN zero﹣hunger goal come true.
Yuan Longping was named as"Father of Hybrid Rice".He helped China make a great wonder—feeding nearly 20% of the world's population with less than 9% of the world's farmland.Then Yuan had a much bigger dream—to save the world from hunger.The world is seeing China's sea rice as a way to fight food insecurity.
"I had a dream.Rice was as high as sorghum （高粱）；ears （穗）were as long as brooms；grains were as big as peanuts （花生）.I could actually enjoy the cool under the rice crops." Yuan said of his childhood dream.And he was one step closer to his dream.
"I'm confident in the future of my country，and I want to do more for my motherland." said Yuan.

Many people go to school for a good education. They learn languages ,history, maths and other subjects. School education is very important and useful, yet no one can learn everything from school. No matter how much a teacher knows, he can’t teach his students everything they want to know. His work is to show his students how to learn.He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves.
It is always more important to know how to study by oneself. It is quite easy to learn something in language or formula (公式 )in maths, but it is difficult to use a formula to find the answer to a maths problem. Great inventors do not get everything from school, but they can invent many things and change the world a lot. Though Thomas Edison invented many things, he didn’t have much school education. How do they do all this ? A lot of things are not taught in the classroom. They get knowledge( 知识 ) from books outside school.
