He didnt like that. So we didnt talk to each other for a while.”Their relationship got going as they competed for
10、the top grade in that course and they started to build a connection because both of them were interested in chemistry. They married in 1942. By 1946, both of the Karles had earned doctorates in physical chemistry, and, after a period of time at the University of Chicago working on the Manhattan Proj

19、created mutations(变异)in 82 genes using an older type of technology. But after thinking carefully about it, she decided to give it a try.After a year of hard work, her lab finally succeeded. Gao worked on genetic engineering in wheat, a crop that is famous for being difficult to work with. Now she is

He is now a professor at Westlake University. In 2012, Cui rode inside Chinas Jiaolong submersible and reached a depth of more than 7,000 meters
21、in the Pacific.Thanks to Jiaolong and the 57-year-old developer, China is now one of only a few nations that can explore the deep sea.

As long as I followed that rule, I could use Dads old cellphone to shoot my movie.“Lets try this again,” I said.This time, Chewy ran the entire length of the backyard.

That is, you can decide to pay for wha
63、t you want or can afford可知PWYD指你可以决定支付你想要或能负担得起的东西,而四项活动中只有Introduction to Waves有PWYD,故选B。2.C细节理解题。根据Science in the Field 活动中的This storytelling night features a scientist sharing his favourite memories of gathering first-hand data on various field trips.以及Join Mark Samuels to find out more in this f
64、un-filled workshop.可知Mark Samuels会分享他最喜欢的收集各种实地考察第一手数据的回忆。故选C。3.B推理判断题。根据Walk on the Wild Side活动中的“Join storyteller Sarah Law to hear science stories about animals.”Introduction to Waves活动中的“Subjects range from sound waves to gravity waves, and from waves of light to crashing waves on the ocean.”Sci
65、ence in the Field活动中的“This storytelling night features a scientist sharing his favourite memories of gathering first-hand data on various field trips.”与Festival Dinner活动中的“Whether you want to explore more about food, or just fancy a talk over a meal, join us to mark the first science festival in Lon
66、don.”可知这四项活动的共同点是它们都是以科学为主题的,故选B。【高频词汇】1.in advance 预先;提前2.all sorts of 各种各样的3.accompany v.陪伴4.range from.to. 包括从到之间的各类事物5.fundamental adj.基本的;根本的6.various adj.各种各样的B语篇解读本文是一篇记叙文,主要叙述了Jerome Karle和Isabella Lugoski这两位科学家在化学领域取得卓越成就的故事。4.C细节理解题。根据第二段中I didnt think I was very polite about my question.
67、I asked him how he got there early and had everything all set up. (我觉得我的问题不太礼貌。我问他怎么这么早到那儿,并且把一切都安排好了。)可知应选C。由第二段中的I asked him how he got there early可知A项错误;由第二段中的there was a young man at the desk next to mine with his equipment all set up可知B项错误;D项“她默默地看着他的实验”,文中未提到这件事情,故D项错误。5.A细节理解题。根据第三段中Their rel
68、ationship got going.were interested in chemistry. (在竞争那门课的最高分时,他们的关系开始发展,他们开始建立联系,因为他们都对化学感兴趣。)可知应选A。B项是他们建立了联系之后才发生的事情;C项“他们在实验室的第一次令人愉快的谈话”,由第二段内容可知他们在实验室的第一次谈话并不愉快;D项“他们在课程上成功的合作”,文中并未提到相关信息。6.B推理判断题。根据第四段中Working together,.to continue further study.可知第四段主要描述了夫妇俩在化学方面的良好合作。故选B。7.D词义猜测题。让步状语从句Alth
69、ough he was disappointed that the Nobel Committee had ignored Isabellas contribution to that work(尽管他对诺贝尔奖委员会忽视了Isabella对那项工作的贡献感到失望)说明画线词所在的主句与从句在感情色彩上是不同的,因此推断尽管Isabella的贡献被忽视了,但是她很平静。故画线单词意思是“平静的,冷静的”。故选D。A项“慷慨的”;B项“感动的”;C项“震惊的”。【高频词汇】1.get along well(with.)(与)相处融洽2.look back on 回顾;回忆3.run v.进行;运
70、行;经营;跑4.while n.一段时间;一会儿 conj.当的时候;而;虽然pete v.竞争;对抗6.specialize v.专门研究(或从事)7.focus on. 全神贯注于8.award v.授予;给予 n.奖项长难句分析原句Working together, they created what is now called the direct method for determining molecular structures(分子结构), which has allowed scientists to effectively study and copy complex or
71、ganic molecules to continue further study. 分析本句为主从复合句。Working together是现在分词短语作状语;what is now called the direct method for determining molecular structures是一个宾语从句,what在从句中作主语;which has allowed.further 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
72、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 known for using CRISPR-Cas9, the revolutionary gene-editing technique.可
73、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 developer of Chinas record-setting Jiaolong 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。
74、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 devoted to 致力于2.be known for因而出名3.take up开始从事;占据;着手处理4.work on从事5.explore v.探索长难句分析原句At first, Gao was unwilling to take up gene editing us
75、ing CRISPR-Cas9 because her lab at the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences in Beijing had already created mutations(变异)in 82 genes using an older type of technology.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,
76、using an older type of technology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。D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 come and go, disappearing almost as quickly as they
77、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 of community that users of short video apps get is another appealing feature. Liza Koshy.said that she was thrilled when anyone said that her video had “inspired” him.可知,按Liza Koshy所说,短
78、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 Vogue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However, the boom in social media may be.users one way or another.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 ne
79、ws(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。【高频词汇】1.feature n.特征;特色2.trend n.趋势;倾向3.take.by
