21、at Britain，the third season of the year usually has only one name: autumn.But if you travel across the Atlantic，youll find that people use both fall and autumn interchangeably when referring to this time of year，making it the only season in the English language with two widely accepted names. _2_Acc

22、ording to D，fall isnt a modern name that followed the more traditional autumn.The two terms are actually first recorded within a few hundred years of each other，with the term fall being used even a bit earlier._3_ The word is of Germanic origin and meant “picking” or “collecting”，a nod to the act of

23、 gathering and preserving crops in the field before winter.In the 1500s，English speakers began referring to the season separating the hot and cold months as either the fall of the leaf or the spring of the leaf，or fall and spring for short._4_By the end of the 1600s，autumn，from the French word “auto

24、mne” and the Latin “autumnus”，had overtaken fall as the standard British term for the third season.Around the same time England adopted autumn，the firstever British American colonists(殖民者)were voyaging to North America._5_While the former fell out of fashion overseas，it established itself in the loc

25、al vocabulary by the time America won its independence.Today，using both words to describe the season before winter is still a unique American behavior.AThe Americans prefer using fall to using autumn.BWith them they brought the words fall and autumn.CSo what is it about the season that makes it so s

26、pecial?DBut for some reason，only spring had staying power in Britain.EIt is time to gather apples，rice and other things for the farmers.FHowever，what exactly you should call that season depends on where you are.GBefore either word appeared，the season between summer and winter was known as harvest.语篇

27、类型说明文主题语境人与社会文化秋天在英语中的叫法语篇解读文章介绍了秋天在英语中两种不同的叫法及其历史渊源。1解析：考查细节支撑句。空前提到了a new season，空后讲大不列颠和大西洋彼岸对这一季节叫法的不同，故F项符合语境，选项中的that season和depends on where you are分别与文中内容对应。答案：F2解析：考查承上启下句。空前提到秋天有两种叫法，下文是对此的解释，C项“那么是什么让这个季节变得如此特别”连接上下文，符合题意。答案：C3解析：考查段落主旨句。上文提到了一个季节的两种叫法，结合下文的the word可知，空处所填句中应用一个有关秋季另一种叫法的

28、单词，G项“在两个词出现之前，夏季和冬季之间的季节被称为harvest”符合题意。答案：G4解析：考查细节支撑句。上文讲到在16世纪，以英语为母语的人开始用树叶的落下(简称fall)或生长(简称spring)来指代炎热和寒冷的月份之间的那个季节，空后提到了17世纪末，autumn取代fall成为指代第三个季节的标准英国用词，由此推断，空处应说明spring该词的情况，故选D。答案：D5解析：考查细节支撑句。空前讲大约在英格兰采用autumn来指代秋天的同一时间，第一批去美国的英国殖民者开始漂洋过海到了北美，空后提到前一个词虽然在大洋彼岸不再流行，但却在美国独立后站稳了脚跟。B项中的them、t

29、hey对应了空前的the firstever British American colonists，B项中的fall对应了空后的the former。答案：B难句分析：In the 1500s，English speakers began referring to the season separating the hot and cold months as either the fall of the leaf or the spring of the leaf，or fall and spring for short.(Para.3)分析：本句主干是“English speakers b

30、egan referring to the season as either the fall of the leaf or the spring of the leaf.”。现在分词短语separating the hot and cold months作后置定语修饰the season。for short意为“简称”。译文：在16世纪，以英语为母语的人开始用树叶的落下(简称fall)或生长(简称spring)来指代炎热和寒冷的月份之间的那个季节。更上层楼破解长难句之“插入、同位和分割”插入语：从命题角度来看插入语的两个逗号或两个破折号就相当于两个括号，表示对插入语前面的解释和说明。从长难句

31、的处理角度来看，插入语扮演的角色就是可以作为整体提出来放到一边最后处理，例如：She，I think，has no feeling for your trouble.我想，她对你的遭遇无动于衷。同位语：一般情况下，跟在某些名词后表示该名词内容或身份的词或句都叫同位语。例如：People here，men and women，old and young，supported the project.这儿的男女老少都支持这项工程。分割：在句子本该连在一起的成分中间加入其他成分，常见的分割有：主谓分割、动宾分割、定语(从句)分割等。例如：The theory，formed thousands of y

32、ears ago，which people believed in，is now proved to be wrong by many scientists.分析：formed thousands of years ago是过去分词短语作后置定语修饰the theory；which people believed in是非限制性定语从句，也修饰the theory。本句主干是“The theory is now proved to be wrong by many scientists.”。译文：几千年前人们深信不疑的理论现在被很多科学家证明是错误的。“After improving the

33、pointing accuracy of telescope through a neural network，space debris with a cross sectional area of one square meter(10 square feet)and a distance of 1，500 kilometers(932 miles)can be identified，” Tianming Ma，an author of the study from the Chinese Academy of Surveying and Mapping，Beijing and Liaoni

34、ng Technical University，Fuxin，said in a statement.(阅读理解Para.1)分析：直接引语部分是一个复杂的简单句，主语是space debris，谓语是can be identified，with介宾短语with a cross sectional area of one square meter(10 square feet)and a distance of 1，500 kilometers(932 miles)作后置定语修饰主语，after介宾短语为时间状语。an author of the study from the Chinese Academy of Surveying and Mapping，Beijing and Liaoning Technical University，Fuxin是Tianming Ma的同位语。句意：位于北京的中国测绘科学研究院和位于阜新市的辽宁工程科技大学进行了联合研究，该研究的作者之一马天明在一份声明中说，“在通过神经网络提高望远镜的指向精度之后，我们可以探测到横截面积1平方米(10平方英尺)和1，500千米(932英里)远的空间碎片。”
