Squishy Cellphones Add a Buzz to Calls
Vibrating rubber could be the next big thing in mobile communications.They allow people to communicate by squishing the phone to transmit_______(51)along with their spoken words. According to a research team at the MIT Medical Lab in Cambridge,Massachusetts,the idea will make_______(52)more fun.
Many mobile phones can already be made to vibrate（振动）_______(53 ) ring when you do not want people to know you are getting a call. But these vibrations,_______(54)by a motor spinning an eccentric（离心的、偏离的）weight inside the device, are too crude for subtle com-munication,says Angela Chang of the lab's Tangible Media Group.“They're_______(55)on or off,”she says.
But when you grip Chang's prototype（样机）latex（橡胶）celiphone,your fingers and thumb wrap around five_______(56)speakers. They vibrate_______(57)your skin around 250 times per second.Beneath these speakers sit pressure sensors,so you can transmit vibration as well as_______(58)it. When you squeeze with a finger,a vibration signal is transmitted _______(59)your caller's corresponding finger. Its_______(60)depends on how hard you squeeze.
She says that within a few minutes of being given_______(61)the phones,students were using the vibration feature to add emphasis to what they were saying or to interrupt the other speaker. Over time, people even began to transmit their_______ (62) kind of ad hoc（特别的）“Morse code”,which they would repeat back to show they were following what the other person was saying.“It was pretty easy to communicate,though we didn't specifically pre-arrange _______(63),”says David Milovich,one of the students who tried out the device.
Chang thinks“vibralanguages”could_______(64)for the same reason as texting:some-times people want to communicate something_______(65)everyone nearby knowing what they are saying.“And imagine actually being able to shake someone's hand when you close a business seal,”she says.

Some robots are equipped with______(54)and lights and can send images back to surgeons and others have surgical tools attached that can be controlled______(55).
"We think this is going to replace open surgery," Dr. Dmitry Oleynikov said at a news ______(56).Oleynikov is a specialist in computer-assisted surgery at the University of Nebraska Medical Center in Omaha.
Officials hope that NASA will teach______(57)to use the robots soon enough so that surgeries could one day be performed in space.
On earth,the surgeons could control the robots themselves from other locations.For example, the robots could enable surgeons in other places to work on injured______(58)on the front line. Researchers plan to seek federal regulatory approval early next year. Tests on______(59)have been successful,and tests on humans in England will begin very soon.

the camera-carrying robots are better than the naked eye,because they send back color images that are______(62).Because several robots can be inserted through one incision,they could reduce the amount and______(63)of cuts needed for surgery,which would decrease______(64)time.
