What makes a human being? Is it ur thughts? Our emtins? Our behavir?
All f these things make us wh we are，but at the center f the matter is the genme (基因组)—the genes inside ur bdies that may determine everything frm ur hair clur t ur intelligence．But if we culd change ur genme，what wuld it mean t us?
In an nline vide psted n Nv 26，He Jiankui，a bilgical researcher frm Suthern University f Science and Technlgy in China，said that he had helped t make the wrld's first genetically edited babies．
These are twin girls，brn in Nvember，with genes edited in an attempt t help them fight against pssible future infectin (感染) with the AIDS virus．
He said that he chse t d this because HIV infectins are a big prblem in China．“I feel such a strng respnsibility that it's nt just t make a first，but als t set an example，” He tld the Assciated Press(AP)．
The annuncement has caused an internatinal strm．Sme believe that success will benefit the families f HIV patients．Cnsidering that HIV is “a majr and grwing public health threat，” attempted gene editing fr HIV is justifiable，Harvard Medical Schl genetics prfessr Gerge Church tld AP．
Hwever，thers think that gene editing technlgy is still unsafe t attempt．
“Gene editing itself is experimental and is still assciated with unexpected mutatins (突变)，causing genetic prblems early and later in life，including the develpment f cancer，” Julian Savulescu，a specialist in ethics at the University f Oxfrd，tld CNN News．
Others fear that this culd pen the dr t using gene editing technlgy t make designer babies．It might give the parents the chices t chse everything frm their baby's eye clr t intelligence．
“Yu culd find wealthy parents buying the latest ‘upgrades’ fr their children，leading t even greater inequality than we already live with，” Marcy Darnvsky，directr f the San Francisc Center fr Genetics，tld CNN News．
Hwever，Merlin Crssley，a bilgist at the University f New Suth Wales，Australia，believes that's a lng way ff．Accrding t him，many genes prduce qualities like height and intelligence — nt t mentin envirnmental influences．
And he believes the technlgy will be better cntrlled in the future．
“It's hard t get genies (妖怪) back int bttles — but I'm ptimistic that this technlgy，which I think f as ‘genetic surgery’，culd be cntrlled quite effectively in the future，” Crssley tld ABC News．
【语篇解读】 本文讨论了对于基因重组这一话题不同的科学家的态度，有的支持这一方面的发展，有的提出担忧，认为对人类进化的干涉可能会导致意料之外的问题，有的相信此技术在未来会得到更好的控制。

C [词义猜测题。画线词句下一段“Hwever，thers think that gene editing technlgy is still unsafe t attempt．”语义转折，表示有人认为基因编辑技术是不安全的，说明前文是赞成基因编辑技术的，从而推断出画线词句“Cnsidering that HIV is ‘a majr and grwing public health threat，’ attempted gene editing fr HIV is justifiable，Harvard Medical Schl genetics prfessr Gerge Church tld AP．”中画线词语justifiable应是“正确的，可行的”的意思，选项C“可接受的”与之意义最为接近。故选C项。]

C [标题归纳题。通读全文可知，文章讨论了对于基因重组这一话题不同的科学家的态度，有的支持这一方面的发展，如第六段；有的提出担忧，认为对人类进化的干涉可能会导致意料之外的问题，如第八、九、十段。选项C“基因编辑：人类的希望还是恐惧”突出主题，强调了两种不同的观点，适合做标题。故选C。]

Why Is 2020 Called a Leap Year?
February 29 cmes up n the calendar nly every fur years．A year with a February 29 might be gd news if yu are paid by the day r the week．But it might be bad news if yu were brn n a February 29． 1 ！
American English has a term fr the unusual situatin．February 29 is called a leap day．And the entire 12­mnth perid with a February 29 in it is called a leap year．2020 is such a year．
In a leap year，the dates jump ver ne day f the week．Let me explain．In 2017，the last day f the year，December 31，fell n a Sunday．In 2018，it fell n a Mnday．In 2019，it fell n a Tuesday．But in 2020，December 31 fell n a Thursday． 2 ．
The reasn fr a leap day r a leap year is because ur calendar des nt fllw the Earth's rbit arund the sun exactly． 3 ．S every fur years，we put all that time tgether int an extra day—r，what is fficially called an intercalary(闰) day．
“Leap” is als an imprtant wrd fr tw ther cmmn American expressins． 4 ．If yu want smene t investigate a situatin cmpletely befre taking actin，yu might say，“Lk befre yu leap．” The ther expressin is a phrase f hpe．Urging smene t “take a leap f faith” means inviting the persn t take actin，even if nt everything abut a situatin is knwn．Interestingly，bth phrases are cmpletely reasnable t say t smene wh is abut t get married．On that nte，sme peple chse t marry n February 29 because it is an unusual date． 5 ．Leap years were believed t be difficult，and leap days unlucky and a bad time t begin anything new．Whatever yu think abut them，the change in the calendar will be gne sn enugh．Then we can return t nrmal，and leap ver February 29 as usual．
A．One is a kind f warning
B．That's why we called it a Leap Year
C．It just leaped right ver Wednesday
D．Each year，we have a little time left ver
E．Yu have t wait three years in between birthdays
F．As a verb，the wrd “leap” means t jump，r t mve quickly
G．Sme ancient peple wuld likely tell cuples nt t d it，hwever
【语篇解读】 本文主要介绍了闰年的情况：由来，习语，以及对其的新旧观点看法。
1．E [根据前文“But it might be bad news if yu were brn n a February 29．”可推知，设空句应是解释“坏消息”。选项E“Yu have t wait three years in between birthdays”提及得等三年才能过生日，这合理解释了为什么出生在2月29日是一个坏消息，与上一句话题一致，意思衔接紧密。故选E项。]
2．C [根据前文“In 2019，it fell n a Tuesday．But in 2020，December 31 fell n a Thursday．”可知，2019年是周二，但在2020年，12月31日是一个星期四。选项C “It just leaped right ver Wednesday”解释了“它正好跳过了星期三”与前两句意思衔接紧密，且呼应前文提及“In a leap year，the dates jump ver ne day f the week．”这一话题。故选C项。]
3．D [根据后文“S every fur years，we put all that time tgether int an extra day — r，what is fficially called an intercalary day．”提及所以每隔四年，会把所有的时间加在一起，变成额外的一天。由此推知，设空句应提及“有时间剩余”，由此才会出现后文的将所有剩余时间加在一起成为额外的一天。选项D呼应后文的“that time”，符合语境。故选D项。]
4．A [根据后文“If yu want smene t investigate a situatin cmpletely befre taking actin，yu might say，‘Lk befre yu leap．’”可知，这种说法是一种警告。选项A放在该句前可体现与该句之间的总分关系，即总说和解释的关系，符合语境。故选A项。]
5．G [根据后文“Leap years were believed t be difficult，and leap days unlucky and a bad time t begin anything new．”解释了为什么不让选择闰年结婚。因此设空句应涉及内容为“不能在闰年结婚”，选项G“Sme ancient peples wuld likely tell cuples nt t d it，hwever”符合语境分析，且句子“hwever”与前文“On that nte，sme peple chse t marry n February 29 because it is an unusual date．”形成对比转折关系。故选G项。]
