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.

I came to the United States from Africa to live with my uncle Jim in Maryland.One year later,I lost my sight because of a serious illness.
Jim told me not to go out.He worried I would get lost or hit by a car.But I was dogged.I told him I'd pay attention.I believed I'd succeed.I must succeed.I must put my will into action.I dreamed of being a broadcaster.
Then a neighbor told me that a public library in Washington D.C.was offering a free course,specially designed for blind people,This was an important chance for me.
But how would I map my way?I knew that the American singer Ray Charles,also blind,got around on his own without a cane (手杖).His secret was to count steps.But I couldn't seem to do that way.Instead I developed my imagination.sensing the layout (布局)of places I Visited and taking notes of landmarks in my mind.
At first,I would have to stop to imagine and map a new space in my mind,The next time I visited that place,I'd use that to find the way.Today.I am used to doing it,But I've still lost my way many times.I'd have to swallow my pride to ask for help,not thinking what others think or say about me.
Sometimes I'd be down and I'd consider giving up.Perhaps my uncle was right.Maybe I'd stay home and wait until someone came to help.On those days when I lost my way,I'd go to bed with a bad feeling.▲.I had e strong wish 10 bear blindness and be successful,and that was usually enough to get me out of bed the next day and try again.
Along the way I learned to be patient with myself and realized that asking for help didn't diminish (贬低)me in any way,I've got three academic degrees so far.
Today,I'm a reporter and broadcaster.I've achieved my dream.
Yes,I've lost my way many times and found it again.Yes,I've come close to being hit by a car but never bee hit by one.When people ask, "Aren't you afraid to be out alone?" the answer to me is clear;I would face danger and find happiness instead of staying home and being unhappy.

Marianne Carus,who started Cricket(蟋蟀)magazine in 1973 and served as Editor﹣in﹣Chief(总主编)until 2012,died on March 3 at the age of 92 this year.
Marianne believed that "only the best of the best is good enough for the young.

Over the years,Cricket has been read by millions of children and given many writers and artists their start.Marianne kept a special box of "love letters" to the magazine.She treasured these letters from Cricket readers,including long﹣ago readers.They told her that their interest in reading had begun with Cricket.
▲She considered other names,such as Troubadour or Taliesin,the singers and storytellers of old who traveled from one place to another to share their songs and stories.Then,one night,she was reading Isaac Bashevi Singer's memoir(回忆录)A Day of Pleasure,about his childhood in Warsaw.In it he wrote:There was a stove in Shosha's apartment behind which there lived a cricket.It chirped the nights through all winter long I imagined the cricket was telling a story that would never end. "That's exactly what Marianne wanted her children's magazine to do-to tell stories that would never end!So the name Cricket became her best choice.

Boyan Slat has been dreaming of cleaning up the world's oceans for a long time.
In 2010,he went on a diving (潜水)vacation in Greece and was shocked."I saw more plastic bags than fish in the water," he said.

Eight hundred years ago,a man in southern Turkey invented an amazing clock.It was more than 7 meters high.At is base(基座)was a life﹣size model elephant.Every half hour,something amazing happened.The whole clock came alive Model birds,dragons,and people started to move.

A bowl with a small hole floats(浮)in a water tank(水箱)inside the elephant's body.As the bowl slowly sinks(下沉),it pulls a rope that moves a human figure.His moving pen shows the number of minutes past he hour.
Every half hour,the water bowl becomes full and sinks completely. Thiscauses a ball to fall from the top of the clock.The movement of the ball causes a phoenix to move and make a sound.
The ball then drops out of a falcon's mouth into the mouth of a Chinese dragon.The weight of the ball causes the dragon's head to move down and the dragon's tail pulls the water bowl back up.
Finally,the ball drops out of the dragon's mouth and into a vase.As the ball lands in the vase,the elephant driver moves and makes a sound.The cycle begins again until there are no more ball in the top of the clock.
