单项选择题

The next time you try for a high-ranking post,you could let your possible boss listen to a recommending(推荐)phone call "made" by US President George W.Bush or British Prime Minister Tony Blair.
Of course ,neither of them could really do that for you--you would just "borrow" their voices.
AT & T labs will start selling speech software that it says is so good at reproducing the sounds of a hmnan voice that it can recreate voices and even bring the voices of long-dead famous people back to life.
The software, which turns printed text into speech, makes it possible for a company to use recordings of a person' s voice to say things that the person never actually said.
Possible customers for the software, which is priced in the thousands of dollars, includes telephone call centers, companies that make software that reads digital (数字的)flies aloud, and makers of automated voice devices(装量).The advances raise several problems.Who ,for example, owns the rights to a famous person's voice? Some experts even believe that new contracts(合同) will be drawn that include voice-licensing clauses.
And although scientists say the technology is not yet good enough to commit fraud (假冒), would the synthesized (合成的)voices at last be able to trick people into thinking that they were getting phone calls or digital audio recordings from people they know?
Even Mr.Fruchterman,one of AT & T labs' possible first customers,said he wondered what the new technology might bring."Just like you can't trust a photograph any more." he said,"you won't be able to trust a voice either."
If the speech software were widely used,_______.

A.peoplewouldnolongerbelieveeachother
B.itwouldnotbenecessarytogoforaspeechbyafamousperson
C.noradioorTVbroadcasterswouldbeneeded
D.recordingofavoicealonewouldnotbetakenasaproofinthecourt

单项选择题Lisa was running late.Lisa,25, had a lot to do at work, plus visitors on the way : her parents were coming in for Thanksgiving from her hometown.But as she hurried down the subway stairs, she started to feel uncomfortably warm.By the time she got to the platform,Lisa felt weak and tired--maybe it hadn't been a good idea to give blood the night before,she thought.She rested herself against a post close to the tracks.
Several yards away,Frank,43, and his girlfriend,Jennifer, found a spot close to where the front of the train would stop.They were deep in discussion about a house they were thinking of buying.
But when he heard the scream, followed by someone yelling, " Oh, my God, she fell in!" Frank didn't hesitate.He jumped down to the tracks and ran some 40 feet toward the body lying on the rails."No!
Not you!" his girlfriend screamed after him.
She was right to be alarmed.By the time Frank reached Lisa, he could feel the tracks shaking and see the light coming.The train was about 20 seconds from the station.
It was hard to lift her.She was just out.But he managed to raise her the four feet to the platform so that bystanders could hold her by the arms and drag her away from the edge.That was where Lisa briefly regained consciousness ,felt herself being pulled along the ground,and saw someone else holding her purse.
Lisa thought she'd been robbed.A woman held her hand and a man gave his shirt to help stop the blood pouring from her head.And she tried to talk but she couldn't, and that was when she realized how much pain she was in.
Police and fire officials soon arrived, and Frank told the story to an officer.Jennifer said her boyfriend was calm on their 40-minute train ride downtown--just as he had been seconds after the rescue,which made her think about her reaction at the time. "I saw the train coming and I was thinking he was going to die," she explained.
How did Frank save Lisa?

A.Byliftinghertotheplatform
B.Byhelpingherrisetoherfeet
C.Bypullingheralongtheground
D.Bydraggingherawayfromtheedge
