15年的職稱英語理工類AB級考點重點復習筆記
15年職稱英語理工類AB級考點重點復習筆記
2008年教材上新增了大約17篇文章，詞匯選項，閱讀判斷， 概括大意完成句子， 閱讀理解， 補全短文， 完型填空各個題型上都有新增文章。理工類和衛生類新增的文章更體現專業性。新增文章的語言難度和問題考點設置情況在一定程度上反映了08年考題的出題趨勢。
The Tiniest Electric Motor in the World
1. Scientists recently made public the tiniest electric motor ever built. You could stuff hundreds of them into the period at the end of this sentence. One day a similar engine might power a tiny mechanical doctor that would travel through your body to remove your disease.
2. The motor works by shuffling(來回運動) atoms(原子) between two molten metal droplets(小滴) in a carbon nanotube(納米管). One droplet is even smaller than the other. When a small electric current is applied to the droplets, atoms slowly get out of the larger droplet and join the smaller one. The small droplet grows but never gets as big as the other droplet and eventually bumps into the large droplet. As they touch, the large droplet rapidly sops up (吸入)the atoms it had previously lost. This quick shift in energy produces a power stroke(動力行程).
3. The technique exploits the fact that surface tension -- the tendency of atoms or molecules to resist separating -- becomes more important at small scales. Surface tension is the same thing that allows some insects to walk on water.
4. Although the amount of energy produced is small -- 20 microwatts(百萬分之一瓦) -- it is quite impressive(給人印象深刻的) in relation to(與...相比) the tiny scale of the motor. The whole setup is less than 200 nanometers on a side, or hundreds of times smaller than the width of a human hair. If it could be scaled up to the size of an automobile engine, it would be 100 million times more powerful than a Toyota Camrys 225 horsepower V6 engine.
5. In 1988, Professor Richard Muller and colleagues made the first operating(工作的， 運行的) micromotor(微型發動機), which was 100 microns(微米) across, or about the thickness of a human hair. In 2003, Zettls group created the first nanoscale motor. In 2006, they built a nanoconveyor(納米傳送帶), which moves tiny particles along like cars in a factory.
6. Nanotechnology(納米技術) engineers try to mimic nature, building things atom-by-atom. Among other things, nanomotors could be used in optical circuits to redirect light, a process called optical switching. Futurists envision(預想) a day when nanomachines(納米機器), powered by nanomotors(納米發動機), travel inside your body to find disease and repair damaged cells.
