Batteries Built by Viruses　　Not everyone runs from the tiny disease carriers, though3.In Cambridge, Massachusetts4, scientists have discovered that some viruses can be helpful in an unusual way.They are putting viruses to work, teaching them to build some of the worlds smallest rechargeable batteries.　　Belchers team includes Paula Hammond，who helps put together the tiny batteries, and Yet-Ming Chiang， an expert on how to store energy in the form of a battery.Were working on things we traditionally dont associate with nature. says Hammond.　　The ideal battery will store a lot of energy in a small package.Right now，Belchers model battery，a metallic disk completely built by viruses，looks like a regular watch battery.But inside，its components are very smallso tiny you can only see them with a powerful microscope.　　詞匯：　　microorganism n.微生物　　collaborator n.合作者，協(xié)作者　　注釋：　　2.steer clear of：避開，繞開　　4.Cambridge，Massachusetts：馬薩諸塞州的劍橋市。本文第三段提到的the Massachusetts　　5.came up with：提出　　7.These microbatteries may change the way we look at viruses：這些微型電池可能會改變我們看待病毒的方式。作者想表達的意思是：人們一直認為病毒有害無益，現在病毒可用來制作電池，人們對病毒的看法可能會因此而發(fā)生變化。
