It used to be a matter of fact when Peter Pan—a character from James Matthew Barrie's 1911 book—said:“All children,except one,grow up.”1.
According to the NPD Group,a US market research company,sales of toys to adults in the UK increased by more than 20 percent in 2016,three times the pace of the children's toy market itself.These toys ranged from puzzles and Lego building sets（乐高积木）to vehicle models and action figures.And more than half of the sales came from millennials—people born between the 1980s and 2000s.“Adults of the 21st century are channeling their inner child, one toy at a time,”commented website Koreaboo.2.According to Frederique Tutt,all analyst at NPD,the motivation of these grown-ups is to escape the stress of today's fast-paced world.3.“It reminds me of the playful side of life,”Rob Willner,a 25-year-old PhD student in the UK,told The Telegraph when talking about his love for Lego,which he said brings him both comfort and entertainment.
4.To Frank Furendi,a professor at the University of Kent in The UK,the fact that so many adults are pursuing "the thrills of youth" is the evidence that "adulthood has got nothing attractive about it anymore",he told The New York Times."That's actually quite sad."
5.According to Canadian comic book artist Todd McFarlane,collecting toys could simply be a way for people to express their individuality."It's just pop culture stuff.It's stuff that says,I like a little of this and I like a little of that,"he told ABC,News."It's no big deal."So now that over 100 years have passed since Peter Pan,perhaps it's time to introduce a new "fact",as stated in the tagline of the UK fashion brand KIDULT:"Growing old is mandatory（强制性的）,but growing up is optional."
A.But scientists are probably just worrying too much.
B.Why do these kidults turn to toys for pleasure and comfort?
C.This is also why these adults are sometimes referred to as "kidults".
D.They are driven toward the more immediate pleasures brought by toys than those brought by,say, getting a promotion,which is far less easy to achieve.
E.The scientists are concerned that those kidults show roo much individuality.
F.But this "fact" doesn't seem to apply to today's world anymore.
G.Despite this,some social scientists see the trend as disturbing.
Peter Thiel,the billionaire co-founder of PayPal,plans to live to be 120.Compared with some other tech billionaires,he doesn't seem particularly ambitious.Dmitry Itskov,the “godfather” of the Russian Internet,says his goal is to live to 10.000;and Sergey Brin,co-founder of Google,hopes to someday "cure death.
They aren't being ridiculous.Their search is based on real science that could fundamentally change what we know about life and about death.It’s hard to believe,though,since the human search for immortality is both ancient and filled with disastrous failures.Around 200 B.C.,the first emperor of China,Qin Shi Huang,accidentally killed himself trying to live forever;he poisoned himself by eating mercury（水银）pills.Centuries later, the search for eternal life wasn't much safer: In J492,Pope Innocent VIII died after blood transfusions from three healthy boys whose youth he believed he could absorb.
But historical examples haven't discouraged some of the biggest names in Silicon Valley.Thiel,for example,has given $3.5 million to the Methuselah Foundation.Aubrey de Grey,Methuselah's co-founder,says SENS,the nonprofit's main research is devoted to finding drugs that cure several types of age-related damage:"Loss of cells, excessive（过多的）cell division,inadequate cell death,garbage inside the cell,garbage outside the cell,...The idea is that the human body,being a machine,has a structure that determines all aspects of its function,so if we can restore that structure—at the molecular（分子的）and cellular（细胞的）level—then we will restore function too,so we will have comprehensively renewed the body."
But SENS,which has an annual operating budget of $5 million,is small,compared with the Brin-led Project Calico,Google's attempt to “cure death,”which is planning to pump billions into a partnership with medicine giant AbbVie.Google is secretive,but it's said to be building a drug to copy a gene associated with exceptional life span.
Then there's the Glenn Foundation for Medical Research,started by Paul F.Glenn in 1965.Since 2007,the foundation has distributed annual "Glenn Awards,"$60,000 to independent researchers doing promising work on aging.The Glenn Foundation also works closely with the Ellison Medical Foundation,a far younger institution (founded in 1997).Ellison's passion project gives out hundreds of thousands of dollars each year to scholars seeking research on aging.Their decision to fund independent research may be paying off.Research projects funded by Ellison and Glenn appear to be developing into a testable means to stave off old age—for lab mice.The question is: Can those lab results be repeated in humans?
1.Which of the following statements about those billionaires is true?
A. They are determined to dream big.
B. What they are doing is silly and unreasonable.
C. Their plan will end up in failure just like the Chinese emperor.
D. They feel let down by those examples that happened in the past.
2.Which of the following DOESN'T explain the theory behind the project of SENS?
A. Something wrong happens at the molecular and cellular level.
B. Repairing the damage is the key to bringing back the function.
C. Cell death should be prevented and then our body will function well.
D. Structure decides how our body works.
3.According to the context,the underlined word "immortality"is close in meaning to the following expressions (also underlined) except .
A. eternal life B. renewing the body
C. life span D. staving off old age
4.Which of the following is NOT true?
A. Probably the Glenn Foundation with the Ellison Medical Foundation will continue their efforts.
B. The Glenn Foundation with the Ellison Medical Foundation has supported people and projects devoted to the research of aging.
C. The Glenn Foundation with the Ellison Medical Foundation has proved the way of delaying aging in mice.
D. The Glenn Foundation with the Ellison Medical Foundation has wasted their time and money since it cannot be applied to human beings.
