17．Scientists Announce Age of Tailored Cancer Care-Thanks to Your DNA
A decade ago it took tense of millions of pounds and many years to sequence the complete genome of one individual．Now it takes a few hundred pounds and a couple of days to decode the entire DNA of a cancer cell．
The rapid pace of change in DNA sequencing is leading to a transformation in the diagnosis and treatment of cancer．In the coming decade every cancer patient will receive a genetic profile of their disease，scientists predict．
An age of personalized medicine where patients receive tailored treatments based on their DNA rather than just their symptoms could end the one-drug-treats-all approach to cancer treatment，which has failed many patients in the past，they said．
The revolution will also mean that the classic method of testing new drugs and treatments based on large scale of clinical trials with thousands of patients will be replaced by more targeted approach focused on a smaller number of individuals with known genetic profiles．
Rapid DNA sequencing will signal an age where cancer drugs will be made for patients based on the type of DMA mutations （转变） carried within their tumor（肿瘤），scientists said．"In part it might signal a significant shift in the way medicine is performed for cancer in the 21^st century，"said Professor Alan Ashworth，chief executive of the Institute of Cancer Research of London．
"This is not science fiction．It's happening in a number of places around the world but we feel it will be absolutely routine within the next five to ten years for every cancer patient，"said Professor Ashworth，adding that it could mean drugs designed for one type of cancer will be used in the treatment of quite different cancers，as scientists uncover common biochemical pathways that link one disease to another．
"It opens up the possibility of using drugs in a context in which they were not originally developed，"Professor Ashworth said．It could also change the whole approach to drug development and clinical trials．He added，"In the past，drugs have been developed with large clinical trials involving thousands of patients and working out what is best for the average patient．What we are saying now is to look at what is best for the individual patient．It may be that in certain rare cancer types，a drug may be considered effective，even though there may well never be clinical trial evidence to prove it．"

51．The underlined word"tailored"in Para.3probably meansA．

B．well designed
C．conveniently made
D．aiming at common people
52．Compared with the new approach，the old method of drug developmentB．
A．is focused on a small number of patients
B．is based on a large number of tests on patients
C．works out what is best for one particular patient
D．cannot produce trial evidence to prove a drug's effect
53．It can be inferred from the passage thatC．
A．A decade ago patients with unknown genetic profiles cannot be treated．
B．Cancer treatment in the future will be mainly based on the symptoms of the patients．
C．the revolution in cancer treatment is a result of the rapid change in DNA sequencing．
D．Up to now the one-drug-treats-all approach to cancer treatment has been working properly．

17．Tom Brennan was working in a Philadelphia office building when he noticed a black bag．The bag contained a book．
This chance discovery ended a 12-day search by the Library Company of Philadelphia for a historical treasure-a 120-page diary kept 190years ago by Deborah Logan，"a woman who knew everybody in her day，"James Green，the librarian told the magazine American Libraries．
Most of the diary is a record of big events in Philadelphia．It also includes a description of British soldiers burning Washington D．C．in the war of 1812．She describes President James Madison on horseback as"perfectly shaking with fear"during the troubled days．George Washington，she writes，mistook her for the wife of a French man and praised her excellent English．
The adventure of the lost book began on September 4when Cory Luxmoore arrived from England to deliver the diary of his ancestor（祖先）to the Library Company，which he and his wife considered to be the best home for the diary．
Green told American Libraries he had the diary in his possession"about five minutes"when Luxmoore took it back because he had promised to show it to one other person．On returning to his hotel after showing the precious book to Green，Luxmoore was shocked to realize that he had left it in the taxi．
Without any delay，Green began calling every taxi company in the city，with no luck，"I've felt sick since then，"Luxmoore told reporters．According to Green，no one has yet learned how the diary came to the office building．
Tom Brennan received a reward（奖励）of 1，000，Philadelphia gained another treasure for its history，and Luxmoore told reporters，"It's wonderful news．I'm on high"．
