The Supreme Court justices ruled states cannot deny gay men and women the same marriage rights. The decision means the 13 states with bans on same-sexm

11、arriage are no longer able to enforce them.Same-sex couples“ ask for equal dignity in the eyes of the law” . Justice Anthony Kwrote in the majority opinion:“ The Constitution grants them that right.”The decision came after decades of litigation(诉讼)and activism. It set off celebrationsacross the US.

12、In affected states including Georgia, Michigan, Ohio and Texas, same-sex couplesrushed to wed, while officialsin Mississippiand Louisiana said marriages had to wait untilprocedural issues were addressed, reported the BBC.According to“ The New York Times” , the ruling came against the backdrop -ofmov

13、ingfastchanges in public opinion in the US, with polls indicating that most Americans now approve ofsame-sex marriage.US President Barack Obama welcomed the ruling,saying it “ affirms what millionsofAmericans already believe in their hearts.”“ Today, ” he said in a press release,uncertain terms, tha

14、t we have made our union a little more perfect.”Another win.This was the second time the Supreme Court took up same-sex marriage, according to anarticle in“ Business Insider” . The first time, in June 2013, the court made a decision that allowedthe US federal government to recognize same-sex marriag

15、es in states where they were already legal.But at that time, the Supreme Court declined to rule on the broader question about gay marriage: Is there a constitutional (宪法的) right to same-sex marriage? The June 26 ruling gave a positive answer to that question.Justice Kennedy wrote in the majorityopin

16、ionthat the Constitutionshould evolve withsocietal changes.“The nature of injustice is that we may not always see it in our own times, ” he wrote.“ Thegenerations that wrote and ratified the “ Bill of Rights” andthe “ FourteenthAmendment (修正案) ” did not exactly know the extent of freedom in all of i

17、ts dimensions, and so they hoped the future generations can protect the ri ght of all persons to enjoy liberty as we learn its meaning.The Fourteenth Amendment addresses citizenship rights and equal protection of the law. In the June 26 ruling, the Supreme Court declared that the equal protection cl

18、ause of the amendment requires marriage rights be extended to same-sex couples, too.21. According to the passage, which of the following is true?A. The majority of Americans now object to same-sex marriage.B. Gay men and women did not care about the ruling.C. All the US states did not ban same-sex m

19、arriage before the ruling.D. The US president believes the country will be less perfect after the ruling.22. It can be inferred that _.A. before June 26, most Americans have doubt about same-sex marriage.B. this is the first time the Americans have got the same-sex marriage right.C. thanks to the am

20、endment, all the Same-sex couples can get married immediately.D. Americans struggled for decades to win the same-sex right.23. Why does the author refer to Justice Kennedy s “ the nature of injustice is that we may notalways see it in our own times” ?A. The author thinks that it is unfair for same-s

21、ex marriage not to have the marriage right.B. The author wants to show that it is difficult for same-sex marriage couple to get the right.C. The author thinks that in our own times we can not see the justice.D. The author shows his dissatisfaction with the delayed approval of the legal same-sexmarri

22、age.BIf you could change your child s DNA in thetoprotectfuture them against diseases, wouldyou? It could be possible because of technology known as CRISPR-Cas, or just CRISPR. CRISPR involves a piece of RNA, a chemical messenger, designed to work on one part ofDNA; it also uses an enzyme (酶 ) that

23、can take unwanted genes out and put new ones in, according to The Economist. There are other ways of editing DNA, but CRISPR will do it very simply, quickly, and exactly.The uses of CRISPR could mean that cures are developed for everything from Alzheimerto cancer to HIV. Byallowingdoctors to putjust

24、 the right cancer-killinggenes into a patient simmune system, the technology could help greatly.In April scientists in China said they had tried using CRISPR to edit the genomes (基因组 )of human embryos. Though the embryos would never turn into humans, this was the firsttimeanyone had ever tried to ed

25、it DNAfrom human beings. Withthis in mind,the US NationalAcademy of Sciences plans to discuss questions about CRISPR伦理问题s).ethics (For example, CRISPR doesn t work properly yet. As well as cutting the DNA it is lookingfor, it often cuts other DNA, too. In addition, we currently seem to have too litt

26、le understanding ofwhat DNA gives people what qualities.There are also moral questions around “ playingGod” .Ofcourse, medicine already stopsnatural things fromhappening forexample, it savespeoplefrominfections.Theopportunities to treat diseases make it hard to say we shouldn t keep going.A harder q

27、uestion is whether it is ever right to edit human germ-line (种系 ) cells and makechanges that are passed on to children. This is banned in 40 countriesand restrictedinmanyothers. However, CRISPR means that if genes can be edited out, they can also be edited back in. Itmay be up to us as a society to

28、decide when and where editing the genome is wrong.Also, according to The Economist, gene editing may mean that parents make choices thatare not obviously in the best interests of their children:“ Deaf parents may prefer theirbe deaf too; parents might w ant to make their children more intelligent at

29、 all costs.”In the end, more research is still needed to see what we can and can t do with CRstill a huge mystery how we work,” Craig Mello, a UMass Medical School biologist and NobelPrize winner, told The Boston Globe.“ We re just trying to figure out this amazingly complicatedthing we call life.”2

30、4. What is the article mainly about?A. How CRISPR was developed by scientists. B. What we can and can t do with CRISPR.C. Chinese scientistsimentexperofusing CRISPR to edit human embryos.25. According to the article, the technology of CRISPR _.A. is very safe because it only cuts the DNA it is looki

31、ng forB. is banned in 42 countries and restricted in many othersC. could cause parents to make unwise choices for their childrenD. could help us discover the link between DNA and the qualities it gives people26. It can be concluded from the article that CRISPR _.A. could be helpful in the treatment

32、of cancer and HIVB. allows scientists to edit genomes for the first timeC. is a technology that uses an enzyme to work on RNA and DNAD. has proven to be the most effective way to protect children against diseases27. What is the author s attitude toward CRISPR?A. Supportive.B. Worried.C. Negative.D.

33、Objective.CMy mother believed you could be anything you wanted to be in America. America waswhere all my mother s hopes lay. She had come here in 1949 after losingeverything in China. Butshe never looked back with regret. There were so many ways for things to get better.“ Of course you can be a prod

34、igy , too,” my mother told me when I was nine.“ You can bbest at anything.We” didn immediately pick the right ki nd of prodigy. At first my motherthought I could be a Chinese Shirley Temple. We d watch Shirley s old movies on TV as tthey were training films. My mother would poke my arm and say,You “

35、watchNikan.And”Iwould see Shirley tapping her feet, or singing a sailor song, or pursing her lips into a very round Owhile saying,“ Oh my goodness.”Soon after my mother got this idea about Shirley Temple, she took me to a beauty trainingschool and put me in the hands of a student who could barely ho

36、ld the scissors without shaking. Instead of getting big fat curls, I emerged with an uneven mass of crinkly black fuzz. My mother dragged me off to the bathroom and tried to wet down my hair.“ You look like Negro Chinese,” she lamented, as if I had donepurposethison.In fact, in the beginning, I was

37、just as excited as my mother, maybe even more so. I picturedthis prodigypart of me as many different images, trying each one on for size. I was a daintyballerina girl standing by the curtains, waiting to hear the right music that would send me floatingon my tiptoes. I was Cinderella stepping from he

38、r pumpkin carriage with sparkly cartoon musicfilling the air.In all of my imaginings, I was filled with a sense that I would soon become perfect. Mymother and father would adore me. I would be beyond reproach. I would never feel the need tosulk for anything.But sometimes the prodigy in me became imp

39、atient.“ If you don t hurry up and get mof here, I m disappearing for good,” it warned.“ And then you ll always be nothing.Every night after dinner, my mother and I would sit at the Formica kitchen table. She would present new tests, taking her examples from stories of amazing children she had read

40、and a dozen other magazines she kept in a pile in our bathroom. My mother got these magazines from people whose houses she cleaned. She would look through them all, searching for stories about remarkable children.The first night she brought out a story about a three-year-old boy who knew the capital

41、s of all the states and even most of the European countries. A teacher was quoted as saying the little boy could also pronounce the names of the foreign cities correctly.“ What s the capital of Finland?” my mother asked me, looking at the magazine story.All I knew was the capital of California, beca

42、use Sacramento was the name of the street welived on in Chinatown.“ Nairobi!” I guessed, saying the most foreign word I could thinkShe of.checked to see if that was possibly one way to pronouncebefore“Helsinkishowng”me theanswer.The tests got harder multiplying numbers in my head, finding the queen

43、of hearts in a deckof cards, trying to stand on my head without using my hands, predicting the daily temperatures inLos Angeles, New York, and London.And after seeing mymother s disappointed face once again, something inside of me beganto die. I hated the tests, the raised hopes and failed expectati

44、ons. Before going to bed that night, Ilooked in the mirror and when I saw only my face staring back and that it would always be thisordinary face I began to cry. Such a sad, ugly girl!I made high pitched noises like a crazedanimal, trying to scratch out the face in the mirror.And then I saw what see

45、med to be the prodigy side of mebecause I had never seen thatface before. I looked at my reflection, blinking so I could see more clearly. The girl staring back atme was angry, powerful. This girl and I were the same. I had new thoughts, willful thoughts, orrather thoughts filled with lots of won ts
