1、課時提能練(十四).閱讀理解(2019長沙測評)Scientists found gravitational waves as they watched the effects of two black holes running into each other and forming a much bigger one，a century after Albert Einstein predicted that such an event would send ripples(波紋) through spacetime.Scientists“heard”the wave with the h

2、elp of laser beams(激光束) sent through two pipes which form an angle of 90 between each other and are nearly 2，000 miles apart in the US.That equipment let them glimpse the nature of black holes.Together they made up the Laser Interferometer GravitationalWave Observatory(LIGO)Gravitational waves were

3、first observed in September 2015 and the second detection(發(fā)現(xiàn)) occurred three months later.The third detection，which the astronomers called GW170104，was made on January 4，2017.The astronomers believed their latest finding“provides clues about the directions in which the black holes are spinning”“Blac

4、k holes are beautifully simple.You just need two numbers to describe them completely：mass，how much they bend spacetime，and a spin，how much spacetime moves about them，”said Dr. Christopher Berry of the University of Birmingham，one of the researchers in the project.“But it takes lots of hard work to m

5、easure these from our data.We now have wonderful mass measurements，and are starting to uncover details about the spins of these black holes，which could give evidence for how they formed.”The researchers said their discovery added further evidence to support Einsteins general theory of relativity and

6、 confirmed the existence of previously unknown black holes.More than 1，000 scientists from the LIGO Scientific Collaboration were involved in the project along with an additional 280 researchers from the Europeanbased Virgo Collaboration.Scientists hope gravitational waves will offer a completely di

7、fferent view of the universe，allowing them to study events that might be hidden from traditional telescopes.“We have further confirmation of the existence of stellar(恒星的)mass black holes that are larger than 20 solar masses.We didnt know they existed before LIGO detected them，”MIT researcher David S

8、hoemaker said.【語篇解讀】本文是一篇科普說明文?？茖W(xué)家們第三次探測到引力波，相對論再獲證實，促進(jìn)了黑洞研究。1Who pioneered gravitational waves?ADavid Shoemaker. BChristopher Berry.CScientists from LIGO.DAlbert Einstein.D細(xì)節(jié)理解題。根據(jù)第一段中的“a century after Albert Einstein predicted that such an event would send ripples(波紋) through spacetime”可知，科學(xué)家們的這一發(fā)

9、現(xiàn)發(fā)生在愛因斯坦預(yù)測此事件的一個世紀(jì)后，因此愛因斯坦是引力波的先行者。2How did scientists discover gravitational waves?ABy using laser beams.BBy joining vertical pipes.CBy using traditional telescopes.DBy following the orbit of black holes.A細(xì)節(jié)理解題。根據(jù)第二段第一句話“Scientistsheardthe wave with the help of laser beams(激光束) sent through two pip

10、es which form an angle of 90 between each other and are nearly 2，000 miles apart in the US”可知，科學(xué)家們是通過使用激光束來探測到引力波的。3What can we learn from the last three paragraphs?AMore than 2，000 scientists took part in the event.BScientists have already discovered spins of black holes.CGravitational waves contri

11、buted to black holes research.DThere is no way to find out how black holes are formed.C推理判斷題。根據(jù)第三段中的“The astronomers believed their latest findingprovides clues about the directions in which the black holes are spinning”和第四段中的“We.are starting to uncover details about the spins of these black holes，w

12、hich could give evidence for how they formed”可知，科學(xué)家們第三次發(fā)現(xiàn)引力波給黑洞的旋轉(zhuǎn)方向提供了線索，黑洞的旋轉(zhuǎn)細(xì)節(jié)可能為它們的形成方式提供證據(jù)。即引力波對黑洞的研究有作用。故選C。4What do the scientists think of the application of gravitational waves?AIts controversial. BIts promising.CIts limited.DIts demanding.B觀點態(tài)度題。根據(jù)最后一段中的“Scientists hope gravitational waves

13、 will offer a completely different view of the universe，allowing them to study events that might be hidden from traditional telescopes”可知，科學(xué)家們希望引力波會提供一個完全不同的宇宙觀，使得他們能研究使用傳統(tǒng)望遠(yuǎn)鏡可能發(fā)現(xiàn)不了的事情，即他們認(rèn)為引力波的運用很有前景。故選B項。.閱讀七選五(2019石家莊模擬)How to Be a Good Team LeaderTeamwork is essential in school，sports，and group

18、lds a lot of weight.EAfter all，they all want to contribute in some way.FShow your team that the task is possible，even if difficult.GBut this may not always be what everyone in your team wants.【語篇解讀】本文是一篇說明文，介紹了四條成為優(yōu)秀領(lǐng)導(dǎo)的原則。1G根據(jù)空處前一句“As a leader，you will sometimes have to make a decision in a hurry”可知

19、，作為一個領(lǐng)導(dǎo)者，你有時不得不迅速做出決定；結(jié)合空處后一句“Youd better explain clearly why you made the decision and ask for feedback from your team，which shows that you are a leader with respect”可知，你最好解釋清楚你為什么做出這樣的決定；根據(jù)空處前后兩句的句意可以判斷，空處與前一句形成轉(zhuǎn)折關(guān)系，表示這么做并非團(tuán)隊每個成員想要的，并引出后一句，故G項正確。2A根據(jù)空處所在的位置可知，空處是該段標(biāo)題；由該段第二、第三句“Be patient and spend

20、 some time with the individual to assess why there is an issue.In addition，find a task for everyone no matter what their skill or level is”可知，要有耐心，花些時間和個人討論為什么會有這樣的問題；此外，要給所有人找到任務(wù)。據(jù)此可以判斷，該段主要陳述要關(guān)注每個成員，故A項正確。3E根據(jù)空處前一句“In addition，find a task for everyone no matter what their skill or level is”可知，要給所有

21、人找到任務(wù)，不管他們的技能或水平是什么樣的；據(jù)此可以判斷，空處解釋此舉的原因，故E項(畢竟每個團(tuán)隊的成員都想以某種方式做出貢獻(xiàn))符合語境。4F根據(jù)該段的標(biāo)題“Encourage your team”可知，要鼓勵你的團(tuán)隊成員；結(jié)合空處后一句“Its more likely that your team will get motivated and have the job done at last”可知，你的團(tuán)隊成員很有可能被激勵，從而最終完成工作；據(jù)此可以判斷，空處承上啟下，陳述激勵的方式，故F項(向團(tuán)隊成員證明，即使任務(wù)很困難，也是可能完成的)符合語境。5D根據(jù)空處前一句“You dont

22、have to reward good work with a pay raise”可知，你無需為良好的工作表現(xiàn)加薪；據(jù)此可以判斷，口頭表揚會起到很大的作用，故D項與此處匹配。.語法填空(2019貴陽適應(yīng)性考試)Franklins life is full of charming stories which all young men should know1._ he sold books in Boston，and became the guest of kings in Europe；how he was made Major General Franklin，only to quit

27、n”呼應(yīng)，此處表示事情進(jìn)行的方式，故用副詞how。2became考查動詞時態(tài)。根據(jù)下文的and never stopped可知，此處是并列結(jié)構(gòu)，故用一般過去時。3studying考查動名詞。stop doing sth.意為“停止做某事”，故用動名詞作賓語。4received考查動詞時態(tài)。根據(jù)語境可知，此處和conquered，made，became是并列關(guān)系，故用一般過去時。5political考查形容詞。修飾名詞用形容詞，故用形容詞political修飾名詞leader，在句子中作定語。6to考查介詞。give sth.to.意為“給某物”，故用介詞to。7ability考查詞性轉(zhuǎn)換。根據(jù)

28、冠詞the和介詞of以及上文的management，forethought和wisdom可知，此處用名詞ability表示抽象概念。8especially考查副詞。副詞修飾形容詞、副詞、動詞、介詞短語，甚至整個句子，在句子中作狀語。此處副詞especially修飾整個句子。9as考查介詞。regard.as.意為“把看作”，為固定搭配，故用介詞as。10hearts考查名詞復(fù)數(shù)。heart作“心，內(nèi)心”時為可數(shù)名詞，根據(jù)空前的peoples可知，此處表示復(fù)數(shù)概念，故用復(fù)數(shù)名詞hearts。.短文改錯(2019太原模擬)Do you believe love is the most import
