14.The government of Norway is planning to build an unusual storage center on an island in the Arctic Ocean.The place would be large enough to hold about two million seeds.The goal is to present all crops known to scientists.The British magazine New Scientist published details of the plan last month.The structure will be designed to protect the world's food supply against nuclear war,climate change and other possible threats.It will be built in a mountain on the Norwegian island of Spitsbergen.The mountain is less than one thousand kilometers from the North Pole,the northernmost position on earth.
An international group called the Global Crop Diversity Trust is working on the project.The director of the group,Cary Fowler,spoke to New Scientist.He said the project would let the world rebuild agriculture if,in his word,"the worst came to the worst".Norway is expected to start work next year.The project is expected to cost three million dollars.Workers will drill deep in the side of a sandstone mountain.Temperatures in the area never rise above 0°C.The seeds will be protected behind walls a meter thick and high-security door.
The magazine report says the collection will represent the products of ten thousand years of farming.Most of the seeds at first will come from collections at seed banks in Africa,Asia and Latin America.To last a long time,seeds need to be kept in very low temperatures.Workers will not be present all the time.But they plan to replace the air inside the storage space each winter.Winter temperatures on the island are about eighteen degrees below 0°C.The cold weather would protect the seeds even if the air could not be replaced.
Mr.Fowler says the proposed structure will be the world's most reliable gene bank.He says the plant seeds would only be used when all other seeds are gone for some reason.Norway first proposed the idea in the 1980s.But security concerns delayed the plan.At that time,the Soviet Union was meeting in Rome of the Food and Agriculture Organization.
67.The project is meant toC.
A.increase the world's food output in the future
B.carry out some scientific experiments on plant genes
C.protect crop seeds from dying out in case of possible disasters
D.build an exhibition centre of the world's plant seeds
68.Which of the following statements is TRUE according to the above passage?D
A.The government of Norway will perform the project alone.
B.Seeds to be collected there were produced ten thousands years ago.
C.Spitsbergen is chosen because it is free of the threat unclear war forever.
D.Temperature is a major consideration when choosing the storage place.
69.We can infer from the text thatC.
A.People will get newly-developed seeds from the center every year.
B.The storage center will greatly promote world agriculture
C.Norway had meant to build the storage centre about 30years before.
D.There haven't been any seed storage centers in the world before.
70.What is probably the best title of the passage?B
A.The Best Place to Store SeedsB.Noah's Ark(諾亞方舟)of Plant Seeds in Plan
C.Concerns of World Food SupplyD.A New Way to Feed the Worl.
分析 挪威政府正在計(jì)劃在北冰洋的一個(gè)小島上建立一個(gè)不尋常的存儲(chǔ)中心.地方足夠大可以容納約二百萬(wàn)顆被科學(xué)家認(rèn)識(shí)的種子,英國(guó)新科學(xué)家雜志發(fā)表了這項(xiàng)計(jì)劃的細(xì)節(jié).該建筑是為保護(hù)世界糧食免受核戰(zhàn)爭(zhēng)、氣候變遷及其它可能性威脅而設(shè)計(jì)的.它將建在挪威的斯匹次卑爾根島的一座山上,這座山是距北極點(diǎn)不足一千公里,是地球上最北的位置.
解答 CDCB
67 C 細(xì)節(jié)理解題.根據(jù)第一段的"The structure will be designed to protect the world's food supply against nuclear war,climate change and other possible threats."可知,該建筑是為保護(hù)世界糧食免受核戰(zhàn)爭(zhēng)、氣候變遷及其它可能性威脅而設(shè)計(jì)的.所以這個(gè)項(xiàng)目的目的是保護(hù)農(nóng)作物種子,防止因可能發(fā)生的災(zāi)難而滅絕.故選C.
68 D 推理判斷題.根據(jù)第二段的"To last a long time,seeds need to be kept in very low temperatures."可知,為儲(chǔ)存長(zhǎng)點(diǎn)時(shí)間,種子需要在極低的溫度下儲(chǔ)藏.所以在選擇存儲(chǔ)位置時(shí),溫度是一個(gè)主要的考慮因素.故選D.
69 C 推理判斷題.根據(jù)最后一段的"Norway first put forward the idea in the 1980s."可知挪威最早是在八十年代提出這個(gè)議案的.所以迄今已有二十年左右的歷史了.故選C.
70 B 主旨大意題.文章主要講述了如何通過(guò)建立"種子儲(chǔ)存中心"來(lái)儲(chǔ)存農(nóng)作物的種子,故B項(xiàng)計(jì)劃中的種子的諾亞方舟最合適.
點(diǎn)評(píng) 做閱讀理解時(shí)要快速的瀏覽全文,把握文章主旨大意,帶著問(wèn)題回到原文,尋找細(xì)節(jié)或概括相應(yīng)的答案,最后要理清作者寫作思路.
