【答案】1．wh/that 2．is viewed/has been viewed 3．are 4．changing 5．rughly 6．have prmised 7．whether/if 8．the 9．invitatin 10．t cntinue
【分析】这是一篇说明文。文章介绍了一个由学者团体发行的实践，目的是为了减少学术飞行以应对气候变化危机。
1．考查定语从句。句意：亚特兰大佐治亚科技研究院的教授Kim Cbb是一个少数但是不断增加的少数学者中的一员，因为气候变化，他们正在削减他们的飞机旅行。名词academics后为定语从句且在从句中作主语，应使用关系代词替代，故填that/wh。
2．考查被动语态。句意：对科学家而言，旅行去参加会议、讲座、工作室之类的地方来相聚并交流信息这件事被视为是重要的。描述人们普遍认知的事情用一般现在时，此处也可以表示强调人们从过去到现在的认知，动名词作主语与主谓之间存在被动关系，故填is viewed或has been viewed。
3．考查时态和主谓一致。句意：但是现在Cbb和其他人正在质疑那个想法，推动会议提供更多远程参加的机会以及为了尽自己的能力来应对气候变化危机，他们正在改变他们的个人行为。根据句意可知，此处也应使用现在进行时，主语为复数，故填are。
4．考查时态。句意：但是现在Cbb和其他人正在质疑那个想法，推动会议提供更多远程参加的机会以及为了尽自己的能力来应对气候变化危机，他们正在改变他们的个人行为。分析句子结构可知，此处and连接并列的动词questining和change，故填changing。
5．考查副词。句意：例如，在一个叫“无飞行科学家”的网站上，自从两年前成立以来，大约有200个学者，他们中很多人承诺尽可能少飞行。此处修饰数字用副词rughly“粗略地大约”，故填rughly。
6．考查时态。句意：例如，在一个叫“无飞行科学家”的网站上，自从两年前成立以来，大约有200个学者，他们中很多人承诺尽可能少飞行。根据时间状语“since+过去时间”可知主句应使用现在完成时，故填have prmised。
7．考查宾语从句。句意：对于她的出席，Cbb开始询问邀请她的组织者是否可以远程进行。显然ask后面出现了一个宾语从句，宾语从句句意不完整，whether/if“是否”符合语境，故填whether或if。
8．考查冠词。句意：大约有四分之三的时间，他们同意了。此处特指Cbb询问的时间范围内，故填the。
9．考查名词。句意：当答案是否定的时候，她拒绝了那个邀请。此处需填入名词作动词decline的宾语，故填invitatin。
10．考查动词不定式。句意：他打算继续这个实践。动词plan后面跟动词不定式，plan t d sth“计划做”，故填t cntinue。

Passage 1
（2023秋·湖南·高一长郡中学校考期中）Plastic-Eating Wrms
Humans prduce mre than 300 millin tns f plastic every year. Almst half f that winds up in landfills(垃圾填埋场), and up t 12 millin tns pllute the ceans. S far there is n effective way t get rid f it, but a new study suggests an answer may lie in the stmachs f sme hungry wrms.
Researchers in Spain and England recently fund that the wrms f the greater wax mth can break dwn plyethylene, which accunts fr 40% f plastics. The team left 100 wax wrms n a cmmercial plyethylene shpping bag fr 12 hurs, and the wrms cnsumed and brke dwn abut 92 milligrams, r almst 3% f it. T cnfirm that the wrms’ chewing alne was nt respnsible fr the plyethylene breakdwn, the researchers made sme wrms int paste(糊状物) and applied it t plastic films. 14 hurs later the films had lst 13% f their mass — apparently brken dwn by enzymes (酶) frm the wrms’ stmachs. Their findings were published in Current Bilgy in 2017.
Federica Bertcchini, c-authr f the study, says the wrms’ ability t break dwn their everyday fd — beeswax — als allws them t break dwn plastic. ＂Wax is a cmplex mixture, but the basic bnd in plyethylene, the carbn-carbn bnd, is there as well, ＂she explains, ＂The wax wrm evlved a methd r system t break this bnd. ＂
Jennifer DeBruyn, a micrbilgist at the University f Tennessee, wh was nt invlved in the study, says it is nt surprising that such wrms can break dwn plyethylene. But cmpared with previus studies, she finds the speed f breaking dwn in this ne exciting. The next step, DeBruyn says, will be t identify the cause f the breakdwn. Is it an enzyme prduced by the wrm itself r by its gut micrbes(肠道微生物)?
Bertcchini agrees and hpes her team’s findings might ne day help emply the enzyme t break dwn plastics in landfills. But she expects using the chemical in sme kind f industrial prcess — nt simply ＂millins f wrms thrwn n tp f the plastic.＂
1．What can we learn abut the wrms in the study?
A．They take plastics as their everyday fd.
B．They are newly evlved creatures.
C．They can cnsume plastics.
D．They wind up in landfills.
2．Accrding t Jennifer DeBruyn, the next step f the study is t .
A．identify ther means f the breakdwn
B．find ut the surce f the enzyme
C．cnfirm the research findings
D．increase the breakdwn speed
3．It can be inferred frm the last paragraph that the chemical might .
A．help t raise wrms
B．help make plastic bags
C．be used t clean the ceans
D．be prduced in factries in future
4．What is the main purpse f the passage?
A．T explain a study methd n wrms.
B．T intrduce the diet f a special wrm.
C．T present a way t break dwn plastics.
D．T prpse new means t keep ec-balance.
【答案】1．C 2．B 3．D 4．C
【分析】本文为说明文。文章介绍了一种吃塑料的虫子大蜡螟，它胃中的酶能够降解塑料，这为解决塑料污染提供了新的途径。
1．细节理解题。根据文章第三段Federica Bertcchini, c-authr f the study, says the wrms’ ability t break dwn their everyday fd — beeswax — als allws them t break dwn plastic.可知，研究结果发现，蠕虫分解日常食物的能力让它们可以分解塑料，也就是说它们可以消费塑料。故选C。
22．细节理解题。根据文章第四段The next step, DeBruyn says, will be t identify the cause f the breakdwn. Is it an enzyme prduced by the wrm itself r by its gut micrbes(肠道微生物)?可知，下一步研究是辨清分解的原因，查明这种酶来源于哪里，是虫子自己产生的还是它肠道里的微生物产生的。故选B。
3．推理判断题。根据文章最后一段But she expects using the chemical in sme kind f industrial prcess — nt simply ＂millins f wrms thrwn n tp f the plastic.＂可以推断出，Bertcchini希望这种化学物质将来能在工业生产中使用，而不是仅仅依靠蠕虫来分解塑料。故选D。
4．写作意图题。根据文章第一段最后一句S far there is n effective way t get rid f it, but a new study suggests an answer may lie in the stmachs f sme hungry wrms.可知，有一种新的方法被用于分解塑料。再根据最后一段最后一句But she expects using the chemical in sme kind f industrial prcess — nt simply ＂millins f wrms thrwn n tp f the plastic.＂可知，Bertcchini希望将这种方法推广到工业中。由此可以推知写作意图为介绍一种分解塑料的方法。故选C。
点睛：根据不同文体，推断目的意图。不同的文章可能有不同的写作目的，通常作者的写作目的有以下三种：1) t entertain readers（娱乐读者，让人发笑），常见于故事类的文章。2) t persuade readers（说服读者接受某种观点），常见于广告类的文章。3) t infrm readers（告知读者某些信息），多见于科普类﹑新闻报道类﹑文化类或社会类的文章。阅读时要善于根据文章的文体来学会推断作者的情感态度和目的。本题的最后一题为写作意图题。文章为说明文，主要介绍了一项新的研究发现---蠕虫可以分解塑料。因此可以推着写作意图是告知、告诉读者一种新的分解塑料的方法。
Passag2 2
(河南省郑州外国语学校2022-2023学年高一上学期期中)Happiness is nt a warm phne, accrding t a new study explring the link between yung life satisfactin and screen time. The study was led by prfessr f psychlgy Jean M. Twenge at San Dieg State University (SDSU).
T research this link, Twenge, alng with clleagues Gabrielle Martin at SDSU and W. Keith Campbell at the University f Gergia, dealt with data frm the Mnitring the Future (MtF) study, a natinally representative survey f mre than a millin U. S. 8th-, 10th-, and 12th-graders. The survey asked students questins abut hw ften they spent time n their Phnes, tablets and cmputers, as well as questins abut their face-t-face scial interactins and their verall happiness.
On average fund that teens wh spent mre time in frnt f screen devices — playing cmputer games, using scial media, texting and vide chatting — were less happy than thse wh invested mre time in nn-screen activities like sprts, reading newspapers and magazines, and face-t-face scial interactins.
"The key t digital media use and happiness is limited use," Twenge said. "Aim t spend n mre than tw hurs a day n digital media, and try t increase the amunt f time yu spend seeing friends face-t-face and exercising — tw activities reliably linked t greater happiness."
Lking at histrical trends frm the same age grups since the 1990s, it's easy t find that the increase f screen devices ver time happened at the same time as a general drp-ff in reprted happiness in U. S. teens. Specifically, yung pepled life satisfactin and happiness declined sharply after 2012. That's the year when the percentage f Americans wh wned a smartphne rse abve 50 percent. By far the largest change in teens' lives between 2012 and 2016 was the increase in the amunt f time they spent n digital media, and the fllwing decline in in-persn scial activities and sleep.
5．Which methd did Twenge's team use fr the study?
A．Calculating students' happiness.
B．Asking students certain questins.
C．Analyzing data frm a survey.
D．Ding experiments n screen time.
6．Hw des the authr develp the finding f the study in paragraph 3?
A．By making a cmparisn.
B．By giving an example.
C．By making an argument.
D．By intrducing a cncept.
7．What is the purpse f the last paragraph?
A．T draw a cnclusin frm the study.
B．T ffer sme advice t the readers.
C．T prve scial activities' imprtance.
D．T supprt the researchers' finding.
8．Which f the fllwing can be the best title fr the text?
A．Quitting Phnes Equals Happiness
B．Screen Time Shuld Be Banned
C．Teens' Lives Have Changed Sharply
D．Screen-addicted Teens Are Unhappier
【答案】5．C 6．A 7．D 8．D
【分析】本文是一篇说明文。一项探索年轻人生活满意度和屏幕时间之间关系的新研究表明，幸福不是一部温暖的手机，沉迷于屏幕的青少年更不快乐。
5．推理判断题。根据第二段中的“T research this link, Twenge, alng with clleagues Gabrielle Martin at SDSU and W. Keith Campbell at the University f Gergia, dealt with data frm the Mnitring the Future (MtF) study, a natinally representative survey f mre than a millin U. S. 8th-, 10th-, and 12th-graders. (为了研究这一联系，特文奇与圣地亚哥州立大学的加布里埃尔·马丁和乔治亚大学的W. Keith Campbell一起处理了来自“监控未来”（MtF）研究的数据，该研究是一项针对超过一百万名美国8年级、10年级和12年级学生的全国代表性调查)”可知，Twenge 的团队通过分析一项调查的数据的方式来进行这项研究。故选C。
6．推理判断题。根据第三段“On average fund that teens wh spent mre time in frnt f screen devices — playing cmputer games, using scial media, texting and vide chatting — were less happy than thse wh invested mre time in nn-screen activities like sprts, reading newspapers and magazines, and face-t-face scial interactins. (研究发现，花更多时间在屏幕设备前的青少年——玩电脑游戏、使用社交媒体、发短信和视频聊天——比花更多时间在非屏幕活动（如体育运动、阅读报纸和杂志以及面对面的社会互动）的青少年更不快乐)”可知，作者是通过作比较的方式来阐述研究结果的。故选A。
7．推理判断题。根据最后一段中的“Lking at histrical trends frm the same age grups since the 1990s, it's easy t find that the increase f screen devices ver time happened at the same time as a general drp-ff in reprted happiness in U. S. teens. Specifically, yung pepled life satisfactin and happiness declined sharply after 2012. (看看自上世纪90年代以来同一年龄组的历史趋势，我们很容易发现屏幕设备随着时间的推移而增加的同时，美国青少年报告的幸福感却普遍下降。尤其是2012年后，年轻人的生活满意度和幸福感急剧下降)”可知，最后一段中的这些内容主要是为支持研究发现服务的。故选D。
8．主旨大意题。根据第一段中的“Happiness is nt a warm phne, accrding t a new study explring the link between yung life satisfactin and screen time. (一项探索年轻人生活满意度和屏幕时间之间关系的新研究表明，幸福不是一部温暖的手机)”及对研究的具体介绍可知，文章主要介绍了一项研究发现——那些沉迷于电子屏幕的青少年明显更不快乐。故选D。
