CHICAGO(Reuters)—Smking nt nly can wrinkle(皱纹)the face and turn it yellw—it can d the same t the whle bdy, researchers reprted n Mnday.
The study, published in the Archives f Dermatlgy, shws that smking affects the skin all ver the bdy-even skin prtected frm the sun.
“We examined nn-facial skin that was prtected frm the sun, and fund that the ttal number f packs, f cigarette smked per day and the ttal years a persn has smked were linked with the amunt f skin damage a persn experienced.”Dr. Ylanda, wh led the study, said in a statement.
“In participants lder than 65 years, smkers had significantly mre fine wrinkling than nnsmkers. Similar findings were seen in participants aged 45 t 65 years.” Ylanda’s team added in their reprt.
The researchers tested 82 peple, smkers and nnsmkers, taking pictures f the inner right arms. They ranged, in age frm 22 t 91 and half were smkers. In dependent judges decided hw wrinkled each persn’s skin was.
When skin is expsed t sunlight, especially the face, it becmes carse(粗糙的). Wrinkled and disclred with a pale yellw tint, Ylanda’s team wrte.
Several previus studies have fund that cigarette smking led t premature(过早的)skin aging asmeasured by facial wrinkles, the study said, but little has been dne t measure the aging f skin nt expsed t light.
The reprt did nt discuss die mechanism invlved but previus research has fund that cigarette smke, amng ther things, causes bld vessels(血管)beneath the skin t cnstrict(紧缩), reducing bld supply t the skin.
Smking can als damage the cnnective tissue(组织)that supprts bth die skin and the internal rgans.
28. It can be inferred frm the study .
A. smking wn’t affect skin prtected frm the sun
B. smking will d damage t skin rather than ther rgans
C. smkers ver 65 usually wn’t wrry abut their skin

Until recently, vice clning—r vice banking, as it was then knwn—was a custmized industry which served thse at risk f lsing the pwer f speech t cancer r surgery. Synthesizing(合成) a vice was a lng and expensive prcess. It meant recrding many phrases, each spken many times, with different the histry f the KidPass blg emtinal emphases(重音) and in different cntexts(statement, questin, cmmand and s frth), in rder t cver all pssible prnunciatins.A vice-banking cmpany ften charges a lt and requires a speaker t spend days in a sund studi.
Nt any mre.Sftware exists that can stre pieces f recrded speech which is merely five millisecnds lng, each marked with a precise pitch(音高). These can be put tgether t make new wrds, and adjusted individually s that they fit harmniusly int their new snic hmes. This is much cheaper than cnventinal vice banking, and permits nvel uses t be develped.
This year Viv Text plans t release an app that lets users select the emphasis, speed and level f happiness r sadness with which individual wrds and phrases are prduced. Mr. Silbert refers t the emtive quality f the human vice as “the ultimate instrument”. Yet this pwer als trubles him. Viv Text licenses its sftware t Hasbr, an American tymaker keen t sell increasingly interactive playthings. Hasbr is aware, Mr. Silbert ntes, that withut safeguards a naughty child might, fr example, type implite wrds n his mther’s smartphne in rder t see a yunger sibling burst int tears n hearing them spken by a ty using mum’s vice.
Mre trubling, when tested against vice-bimetrics sftware like that used by many banks t blck unauthrized access t accunts, mre than 80% f the fake vices tricked the cmputer. Alan Black, ne f Festvx’s develpers, thinks systems that rely n vice-ID sftware are nw “deeply, fundamentally insecure”.
Dr. Saxena and his clleagues asked vlunteers if a vice sample belnged t a persn whse real speech they had just listened t fr abut 90 secnds. The vlunteers recgnized clned speech as such nly half the time(ie, n better than chance). The utcme, accrding t Gerge Papcun, an expert witness paid t detect fake recrdings prduced as evidence in curt, is the appearance f a technlgy with “enrmus ptential value fr disinfrmatin”.
As might be expected, cuntermeasures t recgnize such deceptin(欺骗) are being develped.
Nuance Cmmunicatins, a maker f vice-activated sftware, is wrking n algrithms(算法) that detect tiny skips in frequency at the pints where slices f speech are stuck tgether. Adbe, best knwn as the marker f Phtshp, an image-editing sftware suite, says that it may add digital watermarks t speech synthesized by a vice-clning sftware called VC it is develping. Such technlgy may help cmputers recgnize suspicius speech. Even s, it is easy t imagine the chas that might be created in a wrld which makes it easy t put authentic-sunding wrds int the muths f ppnents—be they clleagues r heads f state.
32. Paragraphs 1 and 2 are mainly abut .
A. significant elements influencing vice clning
B. pssible applicatins f vice clning in reality
C. cmplexities f creating a synthetic cpy f a vice
D. differences between traditinal and existing vice banking
33. What’s Hasbr’s attitude twards Viv Test’s new app?
A. Optimistic.B. Cnservative.C. Uncncerned.D. Subjective.
34. The experiment carried ut by Dr. Saxena and his clleagues shws that vlunteers .
A. identified clned speech in abut 45 secnds
B. preferred a real speech t a vice sample
C. prved nly a little harder t fl than sftware
D. fund it hard t use the sftware t recrd their vices
35. What can we infer frm the last paragraph?
A. Investments shuld be increased t advance vice clning.
B. Lng-term measures shuld be taken t ppularize the idea f vice clning.
C. Disagreements amng firms abut the way t treat vice clning are getting serius.
D. Prblems f vice clning are unavidable despite the effrts that have been made.

Americans d nt mean that everyne shuld be 50 equal when they say they believe in equality f pprtunity. 51, they d mean that each persn shuld have an equal chance fr success. Abraham Lincln nce said, “We wish t 52 the humblest(最微贱的) man an equal chance t get rich with everybdy else. When ne starts pr, free sciety is 53 that he knws he can 54 his cnditin.”
Hwever, cmpetitin is the price t be 55 fr his equality f pprtunity. Americans match their energy and intelligence against that f thers in a cmpetitive cntest fr success, because they believe cmpetitin 56 the best in any persn. Indeed, the pressure f cmpetitin causes an American t be 57, but it als places a cnstant emtinal stress n him. In fact, in a sciety that gives s much 58 t thse “winners”, 59 des nt cmpete successfully fr whatever reasn never 60 int it as well as thse wh d.

Until recently, vice clning—r vice banking, as it was then knwn—was a custmized industry which served thse at risk f lsing the pwer f speech t cancer r surgery. Synthesizing(合成) a vice was a lng and expensive prcess. It meant recrding many phrases, each spken many times, with different the histry f the KidPass blg emtinal emphases(重音) and in different cntexts(statement, questin, cmmand and s frth), in rder t cver all pssible prnunciatins.A vice-banking cmpany ften charges a lt and requires a speaker t spend days in a sund studi.
Nt any mre.Sftware exists that can stre pieces f recrded speech which is merely five millisecnds lng, each marked with a precise pitch(音高). These can be put tgether t make new wrds, and adjusted individually s that they fit harmniusly int their new snic hmes. This is much cheaper than cnventinal vice banking, and permits nvel uses t be develped.
This year Viv Text plans t release an app that lets users select the emphasis, speed and level f happiness r sadness with which individual wrds and phrases are prduced. Mr. Silbert refers t the emtive quality f the human vice as “the ultimate instrument”. Yet this pwer als trubles him. Viv Text licenses its sftware t Hasbr, an American tymaker keen t sell increasingly interactive playthings. Hasbr is aware, Mr. Silbert ntes, that withut safeguards a naughty child might, fr example, type implite wrds n his mther’s smartphne in rder t see a yunger sibling burst int tears n hearing them spken by a ty using mum’s vice.
Mre trubling, when tested against vice-bimetrics sftware like that used by many banks t blck unauthrized access t accunts, mre than 80% f the fake vices tricked the cmputer. Alan Black, ne f Festvx’s develpers, thinks systems that rely n vice-ID sftware are nw “deeply, fundamentally insecure”.
Dr. Saxena and his clleagues asked vlunteers if a vice sample belnged t a persn whse real speech they had just listened t fr abut 90 secnds. The vlunteers recgnized clned speech as such nly half the time(ie, n better than chance). The utcme, accrding t Gerge Papcun, an expert witness paid t detect fake recrdings prduced as evidence in curt, is the appearance f a technlgy with “enrmus ptential value fr disinfrmatin”.
As might be expected, cuntermeasures t recgnize such deceptin(欺骗) are being develped.
Nuance Cmmunicatins, a maker f vice-activated sftware, is wrking n algrithms(算法) that detect tiny skips in frequency at the pints where slices f speech are stuck tgether. Adbe, best knwn as the marker f Phtshp, an image-editing sftware suite, says that it may add digital watermarks t speech synthesized by a vice-clning sftware called VC it is develping. Such technlgy may help cmputers recgnize suspicius speech. Even s, it is easy t imagine the chas that might be created in a wrld which makes it easy t put authentic-sunding wrds int the muths f ppnents—be they clleagues r heads f state.
32. Paragraphs 1 and 2 are mainly abut .
A. significant elements influencing vice clning
B. pssible applicatins f vice clning in reality
C. cmplexities f creating a synthetic cpy f a vice
D. differences between traditinal and existing vice banking
33. What’s Hasbr’s attitude twards Viv Test’s new app?
A. Optimistic.B. Cnservative.C. Uncncerned.D. Subjective.
34. The experiment carried ut by Dr. Saxena and his clleagues shws that vlunteers .
A. identified clned speech in abut 45 secnds
B. preferred a real speech t a vice sample
C. prved nly a little harder t fl than sftware
D. fund it hard t use the sftware t recrd their vices
35. What can we infer frm the last paragraph?
A. Investments shuld be increased t advance vice clning.
B. Lng-term measures shuld be taken t ppularize the idea f vice clning.

Hwever, cmpetitin is the price t be 55 fr his equality f pprtunity. Americans match their energy and intelligence against that f thers in a cmpetitive cntest fr success, because they believe cmpetitin 56 the best in any persn. Indeed, the pressure f cmpetitin causes an American t be 57, but it als places a cnstant emtinal stress n him.
