Question

    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.

2.What can we learn from Paragraph 3?

A.The researchers from China won’t plant saltwater rice on farms in 2020.

B.The experiment of setting up saltwater rice farm will cost much money.

C.Chinese researchers hope to plant saltwater rice on more farms by doing experiments.

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.

Answer

1.B

2.C

3.A

4.D

【解析】

中国科学家在迪拜沙漠中实验培植一种生长在咸水中的水稻，如果这项实验在迪拜恶劣的耕作气候中取得成功，迪拜有可能在全国10%的土地种植盐水稻，这个产量可以养活整个阿拉伯世界。

1.细节理解题。根据第一段“A team of Chinese scientists has tried to develop a kind of rice that grows in salt water.”可知，中国科学家在迪拜沙漠中实验培植一种生长在咸水中的水稻。故选B。

2.大意概括题。根据第三段“They hope to plant saltwater rice on more farms in 2020.”可知，中国科学家希望在2020年种植更多的盐水稻。故选C。

3.词义猜测题。根据they的这句话“…then the farms could “feed the whole Arab world and they help to ensure food security.”可知，这是一个并列句，they指的是第一个句子的主语the farms。故选A。

4.推理判断题。根据最后一段“By planting saltwater rice on just one-tenth of this land, we hope it will feed over 200 million more people.”可知，袁隆平认为盐水稻的成功能够带来巨大的价值。这对有着超过一百万平方公里的土地因为含盐量过多而闲置的中国来讲是充满希望的一个消息。故选D。
