A successful experiment (实验) in the deserts of Dubai (迪拜) may deal with hunger around the world. A team of Chinese scientists has tried to develop a kind of rice that grows in salt water. Not only that, it produces far more rice than you can imagine.
Back in January, 2018, the researchers were invited to plant some of the saltwater rice in different areas of the desert. Usual water is too expensive to waste on rice in those desert areas. After five months of growth, they produce up to 7.8 tons of rice a hectare (公顷). At the same time, the world average (平均数) stands at 3.3 tons a hectare.
The researchers from China are continuing the experiment by setting up a 100-hectare salt-water rice farm in 2019. It will show the costs of production and different farming skills. They hope to plant saltwater rice on more farms in 2020.
Their dream is to cover up to 10% of the country with the saltwater rice fields—and if the skills are successful in Dubai’s bad farming weather, then the farms could “feed the whole Arab world and they help to ensure (确保) food security (安全)”.
Yuan Longping is the “father of hybrid rice” and leader of the research group. He says that there are over l million square kilometers of land in China that is not used because there is too much salt in the soil. By planting saltwater rice on just one-tenth of this land, we hope it will feed over 200 million more people.
1.What kind of water do the researchers use to grow rice?
A.Usual water. B.Salt water. C.Hot water. D.Cold water.

D.The experiment won’t show any different farming skills.
3.What does the underlined word “they” refer to?
A.The farms. B.The skills. C.The scientists. D.The Arab world.
4.What does Yuan Longping think of saltwater rice?
A.It’s terrible. B.It’s impossible. C.It’s unnecessary. D.It’s hopeful.
