3.The Israeli farmers who pioneered the revolutionary technology known as drip irrigation weren't trying to solve one of the world's most urgent problems.They were just trying to survive.They lived in the desert,and they didn't have enough water to grow their crops.In its simplest form,it was little more than a pipe with holes in it.But behind each hole was a hi-tech dripper that let out just the fight amount of water.Snaked along a row of crops so that the holes were positioned directly above the roots,the pipe could direct each precious drop of water directly to the plants,getting a bigger harvest while using a very small amount of the water.
Over time,the farmers improved upon the technology,perfecting the drippers that regulated the flow of water,and connecting the pipelines to computers that could determine exactly how much water each plant needed and when.
If the global population kept growing,the rest of the world would increasingly resemble their little community in the desert.So they began selling their irrigation systems in other parts of the world,eventually expanding to more than 110countries.Netafirm,the company says it's lifting people out of poverty and conserving water at a time when the importance of doing so has never been clearer.
The mass adoption of drip irrigation won't save the world by itself.To avoid the coming catastrophe,nearly everybody will,in some way,have to do more with less,perhaps through accepting and using other new technologies.Otherwise,it's going to get ugly.

分析 本文属于议论文阅读,作者通过这篇文章向我们介绍了以色列人们因为缺水而发明了一种"革命技术"--滴灌,他们用更少的水得到了更多的收获,因此这种技术造福了世界上所有缺水的地区,能节省很多的灌溉用水.
解答 32.C 细节理解题,根据第二段the pipe could direct each precious drop of water directly to the plants,getting a bigger harvest while using a very small amount of the water.可知滴灌用极少量的水得到更大的收获,使灌溉更有效,因此被称为"革命技术",故选C.
33.A 推理判断题,根据第一段They were just trying to survive.They lived in the desert,and they didn't have enough water to grow their crops.可知他们生活在沙漠中,没有足够的水灌溉庄稼,因此这个问题是缺水,故选A.
34.B 细节理解题,根据第三段Over time,the farmers improved upon the technology,perfecting the drippers that regulated the flow of water,and connecting the pipelines to computers that could determine exactly how much water each plant needed and when.可知滴灌可以通过调节水的流量来帮助农民种植庄稼,故选B.
35.A 推理判断题,根据第二段getting a bigger harvest while using a very small amount of the water.可知滴灌可以用更少的水获得更大的收获,故选A.
点评 考查学生的细节理解和推理判断能力.做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确选择.在做推理判断题时不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
