(2021全国甲卷,阅读理解D)——天才的标准Wh is a genius?This questin has greatly interested humankind fr centuries.Let’s state clearly: Einstein was a genius.His face is almst the internatinal symbl fr genius.But we want t g beynd ne man and explre the nature f genius itself.Why is it that sme peple are s much mre intelligent r creative than the rest f us?And wh are they?
In the sciences and arts,thse praised as geniuses were mst ften white men,f Eurpean rigin.Perhaps this is nt a surprise.It’s said that histry is written by the victrs,and thse victrs set the standards fr admissin t the genius club.When cntributins were made by geniuses utside the club—wmen,r peple f a different clr r belief—they were unacknwledged and rejected by thers.
A study recently published by Science fund that as yung as age six,girls are less likely than bys t say that members f their gender(性别) are “really, really smart.”Even wrse,the study fund that girls act n that belief: Arund age six they start t avid activities said t be fr children wh are “really, really smart.”Can ur planet affrd t have any great thinkers becme discuraged and give up?It desn’t take a genius t knw the answer: abslutely nt.
Here’s the gd news.In a wired wrld with cnstant glbal cmmunicatin,we’re all psitined t see flashes f genius wherever they appear.And the mre we lk,the mre we will see that scial factrs (因素) like gender,race,and class d nt determine the appearance f genius.As a writer says,future geniuses cme frm thse with “intelligence,creativity, perseverance (毅力),and simple gd frtune,wh are able t change the wrld.”
真题再做32.What des the authr think f victrs’ standards fr jining the genius club?A.They’re unfair.　B.They’re ’re bjective.D.They’re strict.答案 A解析 推理判断题。根据第三段的“When cntributins were made by geniuses utside the club—wmen,r peple f a different clr r belief—they were unacknwledged and rejected by thers.”可知,俱乐部之外的天才所作出的贡献,包括女人、不同肤色或信仰的人,都不被他人承认并遭他人拒绝,即胜利者对加入天才俱乐部的标准是不公平的,故选A项。
33.What can we infer abut girls frm the study in Science?A.They think themselves lk up t great see gender differences earlier than are likely t be influenced by scial beliefs.答案 D解析 推理判断题。由第四段的“Even wrse,the study fund that girls act n that belief: Arund age six they start t avid activities said t be fr children wh are ‘really,really smart.’”可知,研究发现女孩们会按照这种观念行事:在六岁左右,她们开始避免参加那些所谓“非常非常聪明”的孩子才会参与的活动,说明女孩们可能会受社会观念的影响,故选D项。
34.Why are mre geniuses knwn t the public?A.Imprved glbal discriminatin against f victrs’ in peple’s scial psitins.答案 A解析 细节理解题。根据最后一段的“In a wired wrld with cnstant glbal cmmunicatin,we’re all psitined t see flashes f genius wherever they appear.”可知,在一个全球通信不断的有线世界里,我们随时随地都能看到天才的闪耀。由此可知,是改进后的全球通信让更多天才为公众所知,故选A项。
35.What is the best title fr the text?A.Geniuses Think AlikeB.Genius Takes Many FrmsC.Genius and IntelligenceD.Genius and Luck答案 B解析 标题归纳题。通读全文可知,本文主要介绍了“天才”的定义标准及其演变,因此B项“天才的多种表现形式”最能概括本文的内容和主题,故选B项。
语言能力1.掌握构词知识
3.积累高频词块(1)set a standard 　　　　　　　　　 (2)even wrse 　　　　　　　 (3)act n sth 　　　　　　　　　　　 (4)affrd t d sth 　　 　　　　　　　 (5)be psitined t d sth 　　　　　　　　　　　　 
制定标准　更糟糕的是　依据某事行事　 承担起做某事(的责任)　 已准备好做某事
4.赏析续写佳句As a writer says,future geniuses cme frm thse with “intelligence,creativity,perseverance (毅力),and simple gd frtune,wh are able t change the wrld.”　　　　　　 　　,未来的天才来自那些具有“智慧、创造力、毅力和简单的好运气,能够改变世界的人。” 
5.破解复杂句式And the mre we lk,the mre we will see that scial factrs like gender,race,and class d nt determine the appearance f genius.分析:此处是“the+比较级,the+比较级”结构。 在第二个“the+比较级”中,that引导　　　　从句,从句中的主语是scial factrs;“like gender,race, and class”是介词短语作　　　　语修饰　　　　　　　　　。 译文:
scial factrs
我们看得越多,就越会发现社会因素,比如性别、种族和阶级,并不能决定天才的样子。
