Cell Phone Lets Your Secret Out

Your cell phone holds secrets about you. Besides the names and【51】 that you've programmed into it, traces of your DNA linger on the device, according to a new study.

DNA is genetic material that【52】 in every cell. Like your fingerprint, your DNA is unique to you【53】 you have an identical twin. Scientists today routinely analyze DNA in blood, saliva, or hair left【54】 at the scene of a crime. The results often help detectives identify【55】 and their victims. Your cell phone can reveal more about you【56】 you might think.

Method J. McFadden, a scientist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the【57】. This made her wonder whether traces of DNA lingered on cell phones—even when no blood was involved.【58】she and colleague Margaret Wallace of the City University of New York analyzed the flip-open phones of 10 volunteers. They used swabs to collect【59】 traces of the users from two parts of the phone: the outside, where the user holds it, and the【60】 , which is placed at the user's ear.

The scientists scrubbed the phones using a solution made mostly【61】alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones【62】for another week. Then the researchers collected the phones and repeated the swabbing of each phone once more.

The scientists discovered DNA that【63】to the phone's speaker on each of the phones. Better samples were collected from the outside of each phone, but those swabs also picked up DNA that belonged to other people who had apparently also handled the phone.【64】, DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won't remove all traces of evidence from a criminal's device. So cell phones can now be added to the【65】of clues that can clinch a crime-scene investigation.

第2题

Your mobile phone rings, and instead of the usual electronic signals, it’s playing your fa

vorite music. A friend sends your favorite song to cheer you up. One day, a record company might forward new records and music videos to your phone.

The mobile business is getting into the music business. For the moment, the interest is in pleasant ring tones, but some companies are hoping to take full advantage of the next generation of mobile phones ― all – purpose gadgets(小玩意儿)that blend phone, personal stereo, video player and Internet browser into one.

Finally, record companies might send new records and videos to fans who register(注册)their cell phone numbers.

The fans could pass music or songs along to friends― a kind of musical trading card. Unlike Internet tracks, mobile downloads would be easy for record companies to control, said former record industry official Ralph Simon, who is now chairman of Yourmobile, based in Santa Monic, California.

“If you pass a song along to other phones through a network, each phone can be charged,” said Simon. “It’s like going through a toll gate(收费站). There’s more possibility for copyright control than there is on the Internet.”

Massachusetts – Based Converse is offering a service in Portugal and the Netherlands that lets people record tunes on their voice mail or send music as presents to friends. Finally, people might be able to sing karaoke and pass them along. The company is sure that people will want to use music to reach out and touch someone.

“A mobile phone is not a listening machine, and you’ll be disappointed if you think you can change it to a radio,” said Ohad Ouziel, a creative manager for Converse in Israel. “But if someone sends you a phone while you’re on vacation, you appreciate the feedling.”

The underlined word “blend” in the second paragraph most probably means________.

A.send

B.become

C.mix

D.compare

“Massachusetts – based Converse”in the sixth paragraph probably refers to_________.A.a person

B.a city in Israel

C.a state of the USA

D.a company

Record companies __________ the idea of passing songs and music along mobile phones.A.are worried about

B.are interested in

C.try hard to stop

D.take no notice of

According to Ralph Simon it would be easier to _________ through mobile phone network than through the Internet.A.protect copyright of music works

B.send personal messages

C.pass along songs and music

D.send voice mail
