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 (交叉領(lǐng)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 (基因組) 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 (染色體) 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 本文是一篇講述兩位科學家認為由于科技人類壽命更長的科技文.科學家們認為,隨著科學技術(shù)的發(fā)展,人類有可能活到八旬或九旬.此外,通過破解基因密碼,我們可以猜出某些人的長相.
解答 BCCA
32.B細節(jié)理解題.根據(jù)第一段的"…with our current technology humans have the potential to regularly live into their ninth or tenth decade."可知隨著科學技術(shù)的發(fā)展,人類有可能活到八旬或九旬.由此可知,大衛(wèi)•阿古斯博士認為我們預(yù)期壽命會緩慢增加.故選B.
33.C推理判斷題.根據(jù)第三段的"…15 years ago …","Ten years ago …","We also now …","We now …"幾處時間及內(nèi)容,可知文特爾主要強調(diào)了在科技和醫(yī)學上的進步.故選C.
34.C細節(jié)理解題.根據(jù)第三段"We now have the ability to produce a photo of someone straight from their genetic code."可知我們現(xiàn)在有能力從人們的遺傳密碼子直接得出他們的相片.由此可知,通過破解基因密碼,我們可以猜出他們的長相.故選C.
35.A推斷文章出處題.根據(jù)文章內(nèi)容首先可以直接排除B、D選項,本文是一篇科技文而不是研究報告,所以A選項為正確答案.故選A.
點評 本文考察學生的理解推斷能力以及細心程度,只要抓住文章的關(guān)鍵詞,采用尋讀的方法查找細節(jié),就能找到正確答案.
