Jerme Karle and Isabella Lugski met in their first physical chemistry class at the University f Michigan in 1940. Jerme Karle was in his first year f dctral wrk, and Isabella Lugski was in her last year as an undergraduate(大学本科生), and they were labratry partners. Hwever, they didn't get alng well at first.
Isabella Lugski lked back n the past, “I walked int the physical chemistry labratry and there was a yung man at the desk next t mine with his equipment all set up running his experiment. I didn't think I was very plite abut my questin. I asked him hw he gt there early and had everything all set up. He didn't like that. S we didn't talk t each ther fr a while.”
Their relatinship gt ging as they cmpeted fr the tp grade in that curse and they started t build a cnnectin because bth f them were interested in chemistry. They married in 1942. By 1946, bth f the Karles had earned dctrates in physical chemistry, and, after a perid f time at the University f Chicag wrking n the Manhattan Prject, they mved t Washingtn D.C. t jin the United States Naval Research Labratry.
Each specialized in a different aspect f X-ray crystallgraphy(X射线结晶学): Jerme fcused n develping equatins(方程式) that culd determine hw atms(原子) were arranged inside cmplex mlecules, while Isabella ran practical experiments t test hw well the equatins wrked. Wrking tgether, they created what is nw called the direct methd fr determining mlecular structures(分子结构), which has allwed scientists t effectively study and cpy cmplex rganic mlecules t cntinue further study.
Jerme Karle was awarded the Nbel Prize in Chemistry in 1985. Althugh he was disappinted that the Nbel Cmmittee had ignred Isabella's cntributin t that wrk, she was unfazed. At that pint, she had already wn mre awards and prize mney fr her experimental wrk than he had.

Fr decades, China had wanted a Nbel Prize. Tu Yuyu, a researcher wh helped t develp a malaria(疟疾)medicine, finally wn the cuntry that hnr.
In fact, Tu is nt the nly scientist in China wh is catching the wrld's attentin. In 2016, the jurnal Nature published a list f the tp 10 science stars in China. Ga Caixia and Cui Weicheng are tw f them.
Ga Caixia has been devted t genetic engineering fr her whle career. She is knwn fr using CRISPR-Cas9, the revlutinary gene-editing technique that is sweeping thrugh bilgy labs arund the wrld—in crps.
At first, Ga was unwilling t take up gene editing using CRISPR-Cas9 because her lab at the Institute f Genetics and Develpmental Bilgy, Chinese Academy f Sciences in Beijing had already created mutatins(变异)in 82 genes using an lder type f technlgy. But after thinking carefully abut it, she decided t give it a try.
After a year f hard wrk, her lab finally succeeded. Ga wrked n genetic engineering in wheat, a crp that is famus fr being difficult t wrk with. Nw she is cnsidered ne f the best scientists in the wrld at engineering wheat.
Cui Weicheng is the develper f China's recrd-setting Jialng submersible(潜水器). He is nw a prfessr at Westlake University. In 2012, Cui rde inside China's Jialng submersible and reached a depth f mre than 7,000 meters in the Pacific.
Thanks t Jialng and the 57-year-ld develper, China is nw ne f nly a few natins that can explre the deep sea. Jialng can travel deeper than any ther manned research submersible currently in use, which shws China's increasing ambitin and leadership in deep-sea research.

In the past decade, the use f scial media has grwn in a way that n ne culd have guessed. It has turned sme teenagers int celebrities(名人) and turned the famus int the infamus, vernight.
A key feature f scial media, hwever, is its vlatility. Trends cme and g, disappearing almst as quickly as they appeared. S, what were the key scial media trends f 2019?
Shrt vide apps such as TikTk and its Chinese equivalent Duyin, tk the wrld by strm. The Telegraph reprted that TikTk was ranked 8th n Apple's App Stre in April. And Duyin had mre than 300 millin dmestic mnthly active users in June, CNBC said.
Why are these shrt vides—which are rarely lnger than a few minutes—s ppular? Jiang Yige, a Singapre-based analyst at FengHe Fund Management, has a thery. “Shrt vides are ‘just right t fill in the little gaps in ur busy schedules’,” he tld CNBC.
These vides—apart frm being very cnvenient—are imprtant t teenagers because they allw them t express themselves, accrding t Teen Vgue.
The sense f cmmunity that users f shrt vide apps get is anther appealing feature. Liza Kshy, a user f the US app Musically wh has ver 2 millin fllwers, said that she was thrilled when anyne said that her vide had “inspired” him. “It's really I think as shrt vide creatrs that's what we all expect,” she added.
Live streaming is anther feature f ur scial media life that nw seems as natural as sunrise. It's a pretty neat idea: Yu can watch anyne, anywhere, live.
Hwever, China has taken live streaming t a whle new level. In China, mre than 100 millin viewers mnthly watch a live streaming vide. Frbes thught that a number f factrs had led t the ppularity f live streaming. Amng them is viewers' ability t interact while remaining annymus.
Hwever, the bm in scial media may be having side effects t. Fake news is ne serius prblem it arguably causes. Material shared n these platfrms is ften nt checked fr accuracy. The mst basic cntent can be false and can sway users ne way r anther. We use scial media all the time; that desn't mean that we understand the influence it is having n us. We shuld be mindful f bth the time we spend n it and its impact n ur minds.
12.The underlined wrd “vlatility” in Paragraph 2 pssibly means “being ”.
A.changeable B.steady
C.prmising D.vilent
13.Accrding t Liza Kshy, shrt vides are very ppular because .
A.they are very cnvenient
B.they help peple kill time
C.they prvide a sense f cmmunity
D.they allw peple t express themselves
14.What can we learn abut scial media frm the text?
A.The infrmatin frm scial media is highly reliable.
B.When it cmes t scial media, peple nly knw shrt vides.
C.Peple can't cmmunicate with each ther withut scial media.
D.There is still much rm fr scial media t make imprvement.
15.What is the best title fr the text?
A.Rapid Develpment f Scial Media
B.Key Scial Media Trends f 2019
C.Shrt Vides Taking the Wrld by Strm

Curisity
17 Scientists such as Thmas Edisn and Gerge Westinghuse discvered things mainly because they wanted t knw hw things wrked. If a scientist desn't have the drive t ask questins r even wnder, then he/she never gets t the first stage f the scientific prcess.
Patience
18 There are very few jbs that take lnger than this ne. Even if yu think yu have received sme educatin in science, yu still have a lt f scientific research t d. If yu're an instant-gratificatin(即时满足的)type f persn, this may nt be the best chice fr yu.
Ethical(道德的)qualities
In rder t truly discver and use knwledge fr the greater gd, a scientist must have a desire t imprve peple's life as well as the envirnment, since they are linked and they can affect each ther in the lng run. A scientist must reprt findings hnestly regardless f persnal r utside cmmercial(商业的)interests. Sticking t an ld belief cntradicted(反驳)by evidence is dishnest. 19
Wrking habits
An excellent scientist even takes ntes f the smallest bservatin, keeping it in mind and recrding it. 20 He/She als needs t cmmunicate thughts n paper and verbally. Netwrking skills cnnect him/her with clleagues wrking n similar prjects where he/she may discver smething new.
A.Becming a scientist takes a lng time.
B.An excellent scientist must be very curius abut things.
C.It als defines a scientist as smene wh uses scientific methds.
D.Hwever, that belief shuldn't be changed withut pwerful evidence.
E.He/She can wrk well alne r in grups, depending n what's needed.
F.T make discveries in human knwledge, yu have t think differently.
G.One f the main places that many scientists wrk in is the research labratry.

原句 Wrking tgether, they created what is nw called the direct methd fr determining mlecular structures(分子结构), which has allwed scientists t effectively study and cpy cmplex rganic mlecules t cntinue further study.
分析 本句为主从复合句。Wrking tgether是现在分词短语作状语;what is nw called the direct methd fr determining mlecular structures是一个宾语从句,what在从句中作主语;which has study是一个非限制性定语从句,which在从句中作主语。
句意 他们共同努力,创造了现在所谓的测定分子结构的直接法,这使得科学家们能够有效地研究和复制复杂的有机分子,以便继续深入研究。
C
◎语篇解读 本文是一篇说明文,本文讲述了屠呦呦并不是中国唯一一个引起世界关注的科学家。2016年,《自然》杂志发布了中国十大科学明星名单,高彩霞和崔维成就是其中的两位。
8.D 细节理解题。根据第二段内容可知,下文主要讲的是中国科学家高彩霞和崔维成的主要贡献,故D项“介绍更多中国顶尖科学家”为正确答案。A项“为了展示中国长期以来的一个梦想”;B项“为了强调诺贝尔奖的重要性”;C项“为了表扬屠呦呦的贡献”。
9.A 本题询问什么是CRISPR-Cas9。根据文中第三段中的She is knwn fr using CRISPR-Cas9, the revlutinary gene-editing technique...可知CRISPR-Cas9是一种基因编辑技术。故选A。B项“一个科学家在其中工作的实验室”;C项“一种在世界上广泛种植的农作物”;D项“一个从事遗传工程学的研究团队”。
10.B 细节理解题。本题题干询问崔维成对中国最大的贡献是什么?根据第六段第一句Cui Weicheng is the develper f China's recrd-setting Jialng submersible(潜水器).以及最后一段崔维成的发明对中国的影响来看,B项“他研制了中国的蛟龙号潜水器”为正确答案。A项“他在一所大学教有关海洋的课程”;C项“他致力于基因工程”;D项“他到达了海底”。
11.A 主旨大意题。本题题干询问文章最好的标题是什么?本文点出了屠呦呦并详细讲述了中国的高彩霞和崔维成两位科学家及其成就,所以A项“中国的科学明星”为正确答案。 B项“中国的诺贝尔奖梦”是扩大了主题;C项“高彩霞——中国的农作物工程师”和D项“崔维成——中国的深水潜水员”都只是提到了一个科学家,不能概括文章内容,属于以偏概全。
【高频词汇】 1.be devted t 致力于…… 2.be knwn fr因……而出名 3.take up开始从事;占据;着手处理 4.wrk n从事 5.explre v.探索
长难句分析
原句 At first, Ga was unwilling t take up gene editing using CRISPR-Cas9 because her lab at the Institute f Genetics and Develpmental Bilgy, Chinese Academy f Sciences in Beijing had already created mutatins(变异)in 82 genes using an lder type f technlgy.
分析 本句是一个主从复合句,其中because引导原因状语从句,主句中using CRISPR-Cas9是现在分词短语作状语;从句中的主语是her lab,谓语动词是had created,using an lder type f technlgy是现在分词短语作状语。
句意 起初,高不愿意使用CRISPR-Cas9进行基因编辑,因为她在北京的中国科学院遗传与发育生物学研究所的实验室已经使用一种老式技术在82个基因中制造了突变。

◎语篇解读 本文是一篇说明文。文章主要讲述了社交媒体的发展速度惊人,短视频、直播流媒体给人们的生活带来了便利,能够让人们展现自我,并带来认同感。但是,社交媒体的兴起也可能产生副作用,我们应该客观地看待它。
12.A 词义猜测题。根据第二段中的Trends cme and g, disappearing almst as quickly as they appeared. 可知,发展趋势来得快消失得也快。这句话是在解释画线词语,因此该词意为“易变”,故选A。B项“稳定的”,C项“有希望的”和D项“猛烈的,暴力的”均不符合语境。
13.C 细节理解题。根据第六段中的The sense f cmmunity that users f shrt vide apps get is anther appealing feature. Liza that she was thrilled when anyne said that her vide had “inspired” him.可知,按Liza Kshy所说,短视频非常受欢迎在于它的另一个吸引人的特点:短视频应用程序的用户获得了社区意识。故选C。A项“它们很方便”和D项“它们允许人们来表达自己”是第五段中Teen Vgue的观点;B项“它们帮助人们消磨时间”是第四段中Jiang Yige的观点。
14.D 推理判断题。根据最后一段中的Hwever, the bm in scial media may ne way r anther.可知,社交媒体上传播的虚假新闻是一个严重问题,这会影响用户。因此社交媒体还存在问题,仍旧有很大的改进空间。故选D。A项“社交媒体上的信息都是高度可信的”,与最后一段第二句提到的“Fake news(假新闻)”相矛盾,B项“当谈到社交媒体时,人们只知道短视频”与文中七、八段介绍的“直播流媒体作为一种社交媒体而流行”相矛盾,C项“没有社交媒体,人们就无法交流”的说法太绝对,故不选。
15.B 主旨大意题。根据第二段内容社交媒体的主要特征是它的易变性。发展趋势来得快消失得也快。2019年社交媒体的主要趋势是什么?可知,文章接下来回答了这个问题。因此B项“2019年的主要社交媒体趋势”作文章标题最合适。A项“社交媒体的迅速发展”,C项“短视频风靡世界”和D项“直播流媒体——社交媒体的新特征”均不符合题意。
