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（封闭的）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（层）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 本文是一篇科教类阅读，文章主要讲述了几位研究者所研究的一种未来农业的模式：不需要阳光和下雨的室内农业，它不同于温室农业，是一种节能、节水和环保的农业方式，适应性强，无论是都市还是沙漠均可．

解答 CACBD
66．C细节理解题．根据第二段的内容可知，本段主要是列举了世界在满足人类食品需求方面的问题，如城市人口挨饿问题、物价上涨和不稳定问题以及人口增长所带来的问题．选项A、B、D只是世界供应粮食这一大问题中的几个小问题．故选C．
68．A词意猜测题．根据第二段的内容可知，食品的物价在上涨，而后面提到的dryness、floods、the cost of energy可知是物价的影响因素．因此，"buffeted"的意思是"受影响很大"．故选A．
69．C细节判断题．根据第四段"the temperature is kept constant"可知这个温度不会经常变化，故A不对；根据最后一段"sunlight is not only unnecessary"可知这儿的阳光使不需要的，故B不对；根据第一段"controlled light，temperature，wetness，air quality and nutrition"可知这儿的空气质量是需要控制的，但不一定是依靠植物，故D不对；根据第四段"creating similar day and night，but according to the rhythm of the plant"可知这儿的日夜是由植物所"决定的"．故选C．
70．B推理判断题．根据最后两段，Meeuws的农业能够节省大量的水（但不是海水），其工作原理并不同于温室农行，把不利于生产占据大面积的作物，如"corn"和"potatoes"．而根据第一段It could be in a New York high-rise or a complex in the Saudi desert．可知这种农业可以存在许多环境下，适应力是很强的．故选B．
71．D标题概括题．本文主要讲述了几位研究者所研究的一种未来农业的模式：不需要阳光和下雨的室内农业，它不同于温室农业，是一种节能、节水和环保的农业方式，适应性强，无论是都市还是沙漠均可．故选D．
