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.

How quickly can you count from one to ten？Do you use ten different words to do it？Can you do it in English，or do you have to use your first language？Do you count on your fingers？Many people think that numbers and math are the same all over the world．But scientists have discovered that it is not true．
People in different parts of the world use different ways to count on their fingers．In the United States，people begin counting with their first finger，which they extend or stick out．They then extend the rest of their fingers and finally the thumb(拇指)to count to five．Then they repeat this with the other hand to get to ten．In China，people count by using different finger positions．In this way，a Chinese person can easily count to ten on only one hand．
Besides ways of finger counting，scientists have found that cultures and languages are also different when it comes to numbers．Some languages have only a few words for numbers，and others have no words for numbers．A group of scientists studied aboriginal(土著的)people in Australia．There people don’t have hand movements to stand for numbers．They don’t even have words for numbers．However，they are still able to understand different ideas about numbers．
In a similar study，researchers from the Massachusetts Institute of Technology discovered that people of the Piraha tribe(部落)in northwestern Brazil don’t have words for numbers such as“one”or“three”．They are not able to say“five trees”or“ten trees”but can say“some trees”．“more trees”．or“many trees”．Professor Edward Gibson said that most people believe that everyone knows how to count，“but here is a group that does not count．They could learn，but it’s not useful in their culture，so they’ve never picked it up．”
Although all humans are able to understand quantities(数量)，not all languages have numbers and not all people use counting．Number words in a certain language are a result of people needing numbers in their daily lives．Now we know that people have different ideas about numbers and math，too．The writer begins with the four questions in order to________．
| A．make a survey |
| B．interest readers |
| C．tell a story |
| D．solve math problems |
What do we learn from the difference in finger counting between the US and China？

| D．People of different cultures use the same way of finger counting． |
Which of the following is true about aboriginal Australians？
| A．They have only a few words for numbers． |
| B．They have hand movements to stand for numbers． |
| C．They can only count to five on their fingers． |
| D．They can understand different ideas about numbers． |
