16.It's long been known that dogs and cats,with their well developed sense of smell,can be trained to identify the chemicals released by human illnesses.In some cases,researchers have even trained household pets to detect or predict epilepsy(癫痫病).But what if we could put the sense into a microchip(芯片),allowing us to create a breathalyzer(呼吸分析器) for diseases?For Dr.Andrew Koehl,the inventor of the microchip technology at the heart of this digital nose,the technology that will allow us to do just that is already here."We can detect down to parts per billion levels,"Koehl says."To give you a similarity that's equal to one drop in an Olympic size swimming pool."The sensor(感应器) identifies each chemical's make-up in the air.If the sensor is set to a certain level,it will set off an alarm.
Work continues to make it smaller and makes it able to enter the healthcare market.Within several years,the company hopes to develop it as a diagnostic(诊断) tool"What's amazing is that there really are chemicals on your breath that indicate illness.That's been shown though a number of studies and we can detect those,"he said."There have already been a number of research papers published suggesting we can detect many disease."
At the beginning,the technology had been developed for defense purposes.He said the terror caused by the events of September 11had got him thinking about the application of this type of sensor in safety check."Originally it was aimed at detecting things like explosives,poisonous chemicals and other terrors that might occur,"said Dr Koehl.
Eventually the sensor could become a part of many everyday instruments,warning users of which foods are going bad in the fridge or even the best moment to take the roast out of the microwave oven.
You could even,one day,have a digital nose that you could carry in your pocket."More recently we've been looking at user spaces so we're talking to a number of producers of mobile phones and mobile phone parts,"he said."We want to develop a module small enough to put into mobile devices(装置) like phones."
24.It can be inferred from the passage thatC.
A.This type of sensor was designed to prevent disease at first
B.The digital nose can be put into mobile phones at present
C.Users might take the mobile devices with them in near future
D.The new invention has alreay entered the healthcare market
25.The underlined word"detect"(Paragraph1)is closest in meaning toB.
A.protect B.discover C.settle D.remove
26.What does the passage mainly want to tell readers?D
A.Dogs and cats have a strong sense of smell.
B.A new sensor is used to identify chemicals.
C.Modern technology is developing very fast.
D.Digital noses on a microchip can smell diseases.
