【语篇解读】 本文是一篇科普说明文。
科学家们第三次探测到引力波,相对论再获证实,促进了黑洞研究。
1.Whopioneeredgravitationalwaves?
A.DavidShoemaker.
B.ChristopherBerry.
C.ScientistsfromLIGO.
D.AlbertEinstein.
D [细节理解题。
根据第一段中的“acenturyafterAlbertEinsteinpredictedthatsuchaneventwouldsendripples(波纹)throughspacetime”可知,科学家们的这一发现发生在爱因斯坦预测此事件的一个世纪后,因此爱因斯坦是引力波的先行者。

2.Howdidscientistsdiscovergravitationalwaves?
A.Byusinglaserbeams.
B.Byjoiningverticalpipes.
C.Byusingtraditionaltelescopes.
D.Byfollowingtheorbitofblackholes.
A [细节理解题。
根据第二段第一句话“Scientists‘heard’thewavewiththehelpoflaserbeams(激光束)sentthroughtwopipeswhichformanangleof90°betweeneachotherandarenearly2,000milesapartintheUS”可知,科学家们是通过使用激光束来探测到引力波的。

3.Whatcanwelearnfromthelastthreeparagraphs?
A.Morethan2,000scientiststookpartintheevent.
B.Scientistshavealreadydiscoveredspinsofblackholes.
C.Gravitationalwavescontributedtoblackholes'research.
D.Thereisnowaytofindouthowblackholesareformed.
C [推理判断题。
根据第三段中的“Theastronomersbelievedtheirlatestfinding‘providescluesaboutthedirectionsinwhichtheblackholesarespinning’”和第四段中的“We...arestartingtouncoverdetailsaboutthespinsoftheseblackholes,whichcouldgiveevidenceforhowtheyformed”可知,科学家们第三次发现引力波给黑洞的旋转方向提供了线索,黑洞的旋转细节可能为它们的形成方式提供证据。
即引力波对黑洞的研究有作用。
故选C。

4.Whatdothescientiststhinkoftheapplicationofgravitationalwaves?
A.It'scontroversial. B.It'spromising.
C.It'slimited.D.It'sdemanding.
B [观点态度题。
根据最后一段中的“Scientistshopegravitationalwaveswillofferacompletelydifferentviewoftheuniverse,allowingthemtostudyeventsthatmightbehiddenfromtraditionaltelescopes”可知,科学家们希望引力波会提供一个完全不同的宇宙观,使得他们能研究使用传统望远镜可能发现不了的事情,即他们认为引力波的运用很有前景。
故选B项。
