Question

【題目】 A successful experiment (實驗) 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 (公頃). At the same time, the world average (平均數(shù)) 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 (確保) 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

【答案】

【1】B

【2】C

【3】A

【4】D

【解析】

中國科學(xué)家在迪拜沙漠中實驗培植一種生長在咸水中的水稻，如果這項實驗在迪拜惡劣的耕作氣候中取得成功，迪拜有可能在全國10%的土地種植鹽水稻，這個產(chǎn)量可以養(yǎng)活整個阿拉伯世界。

【1】細節(jié)理解題。根據(jù)第一段“A team of Chinese scientists has tried to develop a kind of rice that grows in salt water.”可知，中國科學(xué)家在迪拜沙漠中實驗培植一種生長在咸水中的水稻。故選B。

【2】大意概括題。根據(jù)第三段“They hope to plant saltwater rice on more farms in 2020.”可知，中國科學(xué)家希望在2020年種植更多的鹽水稻。故選C。

【3】詞義猜測題。根據(jù)they的這句話“…then the farms could “feed the whole Arab world and they help to ensure food security.”可知，這是一個并列句，they指的是第一個句子的主語the farms。故選A。

【4】推理判斷題。根據(jù)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，袁隆平認為鹽水稻的成功能夠帶來巨大的價值。這對有著超過一百萬平方公里的土地因為含鹽量過多而閑置的中國來講是充滿希望的一個消息。故選D。
