Question

4．Farming is moving indoors，where the sun never shines，where rainfall is irrelevant and where the climate is always right．The perfect crop field could be inside a windowless building with controlled light，temperature，wetness，air quality and nutrition．It could be in a New York high-rise or a complex in the Saudi desert．It may be an answer to the
The world already is having trouble feeding itself．Half the people on Earth live in cities，and nearly half of those-about 3 billion-are hungry or ill-fed．Food prices，currently increasing，arebuffetedby dryness．Hoods and the cost of energy required to plant，harvest and transport it．And prices will only get more unstable．Climate change makes long-term crop planning uncertain．Fanners in many parts of the world already are using water available to the last drop．And the world is getting more crowded：by mid-century，the global population will grow from 6.8 billion to 9 billion．
To feed so many people may require expanding farmland at the expense of forests and wilderness，or finding ways to completely increase crop output．
Gertjan Meeuws has taken the concept of a greenhouse a step further，growing vegetables and house plants in enclosed（封閉的）and regulated environments．In their research station，water flows into the pans when needed，and the temperature is kept constant．Lights go on and off，creating similar day and night，but according to the rhythm of the plant．
A building of 100 square meters and layers（層）of plants could provide a daily diet of 200 grams of fresh fruit and vegetables to the entire population of Den Bosch，about 140，000 people．Their idea isn't to grow foods that require much space，like corn or potatoes．
Here sunlight is not only unnecessary but can be harmful．Plants need only specific wavelengths of light to grow．Their growth rate is three times faster than under greenhouse conditions．They use about 90 percent less water than outdoors agriculture．And city fanning means producing food near the consumer，and there's no need to transport it long distances．
66．What can we mainly learn from Paragraph 2？C
A．The climate is worse and worse．
B．The city people live a hard life．
C．The world has difficulty feeding its people．
D．The world's population is increasing fast．
67．The underlined word"buffeted"in Paragraph 1 meansA．
A．badly affected        B．prevented      C．demanded      D．well achieved
68．Which of the following is true of the environments in the research station？C
A．The temperature is often changed．
B．Sunshine is in great need for plants．
C．Day and night depends on plants．
D．Air quality is controlled by plants．
69．It can be inferred from the text that Gertjan Meeuws's farmingB   
A．helps save sea water a lot                              
B．is highly adaptable
C．resembles greenhouse agriculture                        
D．suits the production of corn
70．What is the text mainly about？D
A．Development of indoor farming．                         
B．Great Revolution in farming．
C．Advantages of indoor farming．                          
D．Sunless，rainless indoor farming．

Answer 1

分析 本文是一篇科教類閱讀，文章主要講述了幾位研究者所研究的一種未來農(nóng)業(yè)的模式：不需要陽光和下雨的室內農(nóng)業(yè)，它不同于溫室農(nóng)業(yè)，是一種節(jié)能、節(jié)水和環(huán)保的農(nóng)業(yè)方式，適應性強，無論是都市還是沙漠均可．

解答 CACBD
66．C細節(jié)理解題．根據(jù)第二段的內容可知，本段主要是列舉了世界在滿足人類食品需求方面的問題，如城市人口挨餓問題、物價上漲和不穩(wěn)定問題以及人口增長所帶來的問題．選項A、B、D只是世界供應糧食這一大問題中的幾個小問題．故選C．
68．A詞意猜測題．根據(jù)第二段的內容可知，食品的物價在上漲，而后面提到的dryness、floods、the cost of energy可知是物價的影響因素．因此，"buffeted"的意思是"受影響很大"．故選A．
69．C細節(jié)判斷題．根據(jù)第四段"the temperature is kept constant"可知這個溫度不會經(jīng)常變化，故A不對；根據(jù)最后一段"sunlight is not only unnecessary"可知這兒的陽光使不需要的，故B不對；根據(jù)第一段"controlled light，temperature，wetness，air quality and nutrition"可知這兒的空氣質量是需要控制的，但不一定是依靠植物，故D不對；根據(jù)第四段"creating similar day and night，but according to the rhythm of the plant"可知這兒的日夜是由植物所"決定的"．故選C．
70．B推理判斷題．根據(jù)最后兩段，Meeuws的農(nóng)業(yè)能夠節(jié)省大量的水（但不是海水），其工作原理并不同于溫室農(nóng)行，把不利于生產(chǎn)占據(jù)大面積的作物，如"corn"和"potatoes"．而根據(jù)第一段It could be in a New York high-rise or a complex in the Saudi desert．可知這種農(nóng)業(yè)可以存在許多環(huán)境下，適應力是很強的．故選B．
71．D標題概括題．本文主要講述了幾位研究者所研究的一種未來農(nóng)業(yè)的模式：不需要陽光和下雨的室內農(nóng)業(yè)，它不同于溫室農(nóng)業(yè)，是一種節(jié)能、節(jié)水和環(huán)保的農(nóng)業(yè)方式，適應性強，無論是都市還是沙漠均可．故選D．

點評 本文考察學生的理解推斷能力以及細心程度，只要抓住文章的關鍵詞，采用尋讀的方法查找細節(jié)，就能找到正確答案．
