6、es as small as 40 nanometers across。At present,engineers looking for defects in a chip have to peel off the layers and examine the circuits visually;this is one of the obstacles _3_。But the new magnetic microscope is sensitive enough to look inside chips and reveal faults such as short circuits，nick

7、s in the wires or electro migration where a dense area of current picks up surrounding atoms and moves them along.“It is like watching a river flow,”explains Xiao。As well as scanning tiny circuits，the microscope can be used to reveal the internal structure of any object capable of conducting electri

8、city。3 Fpr example,it could look directly at microscopic cracks in an aeroplanes fuselage，_4_.The technique cannot yet pick up electrical activity in the human brain because the current there is too small，but Xiao doesn t rule it out4 in the future。“I can never say never，”he says。Although the resear

11、s we require D to picture the progress of the currents E converting the information into a color picture showing the density F faults in the metal strip of a forged banknote or bacteria in a water 答案与题解：1.D manage to+v。是“设法做成”的意思。picture 在此是动词,“to picture the progress of the cuixents”意为“绘出电流运行图”。2。E

12、 by 在句中引导两个在句法结构上并列的分词短语：一个是measuring subtle changes in the magnetic field of an object,另一个是 converting the information into a color picture showing the density of current at each point。convert。into.。的意思是“把转变为”。3.B“obstacle to+名词性成分”的意思是“的障碍”。4.F faults in the metal strip of a forged banknote 和 bact

13、eria in a water sample 与前文中的 microscopic cracks in an aeroplane s fuselage 在意思上是并列的关系。5.A 这部分所说的体积的减小和所需时间的缩短恰好与前半句中提到的冰箱大小的体积和所需数分钟的时间形成了对比。内容进行仔细校对但是难免会有疏漏的地方但是任然希望完整版年职称英语理工类补全短文模拟习题及答案的内容能 辑可修改如果觉得对您有帮助请收藏以便随时查阅最后祝您生活愉快业绩进步以下完整版年职称英语理工类补全短文 及答案案完整版年职称英语理工类补全短文模拟习题及答案练习完整版年职称英语理工类补全短文模拟习题及答案答(完整版)2017 年职称英语理工类补全短文模拟习题及答案(8)5 内容进行仔细校对但是难免会有疏漏的地方但是任然希望完整版年职称英语理工类补全短文模拟习题及答案的内容能 辑可修改如果觉得对您有帮助请收藏以便随时查阅最后祝您生活愉快业绩进步以下完整版年职称英语理工类补全短文 及答案案完整版年职称英语理工类补全短文模拟习题及答案练习完整版年职称英语理工类补全短文模拟习题及答案答
