3.Professor David Agus,one of leading scientists at the medical revolution,says that he believes that with our current technology humans have the potential to regularly live into their ninth or tenth decade.
Craig Venter,co-founder and CEO of Human Longevity Inc.,says there might be no supposed limit to how long we can live,but that"we need to make sure we can support extra long life on this planet."Huge advancements at the intersection (交叉领域) of medicine and technology,such as big data,are making these kinds of developments in aging possible.
Venter explained that when he first studied the human genome (基因组) 15years ago,there was nothing for him to compare it to.For example,we now know that we vary about 3% from the 6.4billion letters of DNA that we get from our parents.Ten years ago,Venter said he wouldn't have thought that we'd be able to predict someone's age from their genetic code.We also now know that our genetic code is constantly changing,he says.Men,for example,start losing Y chromosomes (染色体) in their 40s and 50s."To help crack (破解) the big data code in medicine,my team have hired the engineer who designed Google Translate,"says Venter."We're using machine learning to try to understand and translate all that data,"he explains."We now have the ability to produce a photo of someone straight from their genetic code."
Therefore,will all this data automatically extend our lifespan?That's a bit more complicated."We're learning new things every six months,"Agus says."These new things make us more complex.That means we're never going to totally understand disease,"he adds."But we don't need to understand it to control it."
32.What is the belief that David Agus holds?B
A.There will be no disease in the future.
B.Our life expectancy will slowly increase.
C.Everyone can live a long life in the future.
D.Advance in technology can make us stop aging.
33.According to Paragraph 3,Venter tries to stressC.
A.the discovery of DNA
B.the secret of the genetic code
C.the progress in technology and medicine
D.the intelligent machine used in research
34.By cracking someone's genetic code,we canC.
A.change his DNA
B.break the big data code
C.guess his appearance
D.stop him from aging
35.Where is the passage most probably taken from?A
A.A science magazine.
B.A research report.
C.A book review.
D.A travel guide.
分析 本文是一篇讲述两位科学家认为由于科技人类寿命更长的科技文.科学家们认为,随着科学技术的发展,人类有可能活到八旬或九旬.此外,通过破解基因密码,我们可以猜出某些人的长相.
解答 BCCA
32.B细节理解题.根据第一段的"…with our current technology humans have the potential to regularly live into their ninth or tenth decade."可知随着科学技术的发展,人类有可能活到八旬或九旬.由此可知,大卫•阿古斯博士认为我们预期寿命会缓慢增加.故选B.
33.C推理判断题.根据第三段的"…15 years ago …","Ten years ago …","We also now …","We now …"几处时间及内容,可知文特尔主要强调了在科技和医学上的进步.故选C.
34.C细节理解题.根据第三段"We now have the ability to produce a photo of someone straight from their genetic code."可知我们现在有能力从人们的遗传密码子直接得出他们的相片.由此可知,通过破解基因密码,我们可以猜出他们的长相.故选C.
35.A推断文章出处题.根据文章内容首先可以直接排除B、D选项,本文是一篇科技文而不是研究报告,所以A选项为正确答案.故选A.
点评 本文考察学生的理解推断能力以及细心程度,只要抓住文章的关键词,采用寻读的方法查找细节,就能找到正确答案.
