[课时作业评价]　　　　主题阅读集群训练 Ⅰ.阅读理解 A Sun Yi finally received an email she had long been waiting for, which contained her final wedding plan.The plan, which had been revised nearly ten times, offered the 29­year­old girl a “new Chinese­style”wedding in March.She described it as “traditional but old­fashioned” and “ritualistic (仪式的) but stylish”． In recent years, traditional Chinese weddings have won popularity again among the country's newly­married.Many of them no longer consider western­style dresses and words of“I do”as important parts of weddings.Instead, they now prefer wearing Tang Dynasty­style clothes and performing traditional rituals at weddings the same way their ancestors did hundreds, even thousands of years ago. In traditional Chinese weddings, couples usually wear red.Red is always a symbol of fortune in Chinese culture, and the hall of the ceremony is also richly decorated in red.Couples will perform a three­step ritual, namely to heaven and earth, to their parents and to each other. In Lanzhou, several wedding planning companies are sparing no effort to promote their“Chinese­style wedding packages”， which offer a wide range of choices for wedding plans.“Chinese­style weddings make up nearly 40 percent of our orders.Customers often need to make reservations six months in advance，” said Zhang, a wedding planner. Wang Yiru, another wedding planner in Lanzhou, Xinxin Wedding Service Company, said the preparation for a Chinese­style wedding is usually very time­consuming and costly. “Wedding ceremonies reflect social and cultural changes.With people's living standards improved, they go for more individual choices，”said Wang Zongli, a professor at Northwest Normal University. 语篇解读：本文是一篇说明文。文章介绍了越来越多的中国新人开始选择传统的中国式婚礼。这一趋势反映了社会文化价值的变化，人们越来越追求个性化的选择。 1．What do the newly­married usually do in a traditional Chinese wedding? A．Perform western rituals. B．Memorize their ancestors. C．Say “I do” to each other. D．Wear Chinese­style clothes. 解析：选D　细节理解题。根据第二段最后一句可知，在中国传统的婚礼上，新婚夫妇通常穿中式服装。 2．Why is red always used in traditional Chinese weddings? A．Red is a symbol of fortune. B．Red is a symbol of money. C．Red is a symbol of heaven. D．Red is a symbol of health. 解析：选A　细节理解题。根据第三段中的“Red is always a symbol of fortune in Chinese culture”可知，红色是好运的象征。 3．What can we infer about Chinese­style weddings? A．People can make a Chinese­style wedding reservation easily. B．More than half couples choose to hold Chinese­style wedding. C．A Chinese­style wedding needs a lot of time and money to hold. D．Some wedding companies think little of Chinese­style wedding. 解析：选C　推理判断题。根据倒数第二段中的“very time­consuming and costly”可知，中国式婚礼需要大量的时间和金钱来举办。 4．What's the best title of this text? A．Some Skills to Hold a Great Traditional Chinese Wedding B．Traditional Chinese Weddings and Old Western Weddings C．Dream to Have a Nice Traditional Chinese Wedding D．Traditional Chinese Weddings Have Regained Popularity 解析：选D　标题归纳题。通读全文可知，文章介绍了越来越多的中国新人开始选择传统的中国式婚礼，包括穿着唐装和进行传统的仪式。故D项“传统的中国婚礼重新流行起来”适合作文章标题。 B In this period of anxiety about the size of our waists and what we consume, simple dietary rules are appealing.“Eat like our ancestors” is a particularly catchy slogan (口号) to live by. But who are these ancestors we are supposed to follow？Are they our great­great­grandparents, cooking healthy things？Or are they hairy animals we imagine “cavemen” to be？The popular ancient diet blames modern health problems on the birth of agriculture, claiming that we should stick to eating meat, nuts and berries. This kind of stone age trend is based on the false assumption that palaeolithic (旧石器时代的) peoples all ate the same food, regardless of their location.Nevertheless, England's 9,000­year­old Cheddar Man would not have eaten the same foods as his contemporaries on the Kenyan plains.The amount of meat peoples ate, and how much was obtained by hunting, are also up for debate. Moreover, the stone age trend focuses on what's perceived to be good for our bodies, without any concern for the rest of nature, including other humans whose livelihoods are threatened by western overconsumption.Were I to eat like my Punjabi farming great­grandparents, my diet would be based on the wheat and milk products that people in the Punjab have relied on for probably at least the last two thousand years.But delicious and “original” as it might be for me to follow its lead, the morals of industrially farmed milk products in the 21st century make the situation more confusing and complicated. Now, probably more than ever before, what we eat connects us to the fate of other beings, human and non­human, and to the fate of our planet.A dogmatic (武断的) approach to this would be a mistake.Better to preserve what's worth keeping and remain clear­eyed about our cooking past, much of which is unknowable, immoral and impossible to follow in any case. 语篇解读：本文是一篇议论文。文章讨论了“像我们的祖先一样吃饭”这一普遍看法，从不同角度驳斥了这一观点，最后明确论点——保留值得保留的东西，并对我们的饮食历史保持清醒的头脑。 5．What does the text concern? A．An ancient study.　　 B．An immoral case. C．A balanced diet. D．A popular belief. 解析：选D　主旨大意题。文章第一段表明，“像我们的祖先一样吃饭”是人们的普通看法。然后下文是从不同角度对这一普遍看法的驳斥。由此可知，本文主要是围绕一个作者不认同的“普遍认识”展开的。 6．Why does the author mention the Cheddar Man in Paragraph 3? A．To illustrate an opinion. B．To present a fact. C．To clarify a concept. D．To introduce a theory. 解析：选A　推理判断题。第三段提到9 000年前的Cheddar Man不会和肯尼亚平原上的同时代人吃相同的食物。文中提到这一点是作为论据来进行驳论，证明“像我们的祖先一样吃饭”这一看法的错误性。因此，文章提到Cheddar Man是为了阐述作者的观点。 7．What does the author focus on in Paragraph 4? A．The eating behavior of our great­grandparents. B．The connection between the food choice and nature. C．The relationship among eating, hunting and farming. D．The impact of food overconsumption on the environment. 解析：选B　段落大意题。分析段落的结构可知，衔接副词Moreover引出“像我们祖先一样吃饭”这个看法的第二处错误——这种石器时代的饮食趋势只关注对我们身体有益的东西，却不考虑大自然的其他方面。再结合下文内容可知，该段分析的是食物的选择与大自然的关系。 8．What is a suitable title for the text? A．Punjabi diet: popular again B．Should we eat like our ancestors? C．Is the fate of the planet in our hands? D．Our cooking past: a complicated history 解析：选B　标题归纳题。首段中的“‘Eat like our ancestors’ is a particularly catchy slogan to live by.”引出人们对饮食习惯的一种普遍认识，接下来作者对这种饮食观点提出异议，从不同方面进行分析论证，并在文章结尾表达了作者的观点。纵观全文，整篇文章都在讨论“我们要不要像我们的祖先那样吃饭”这一问题。所以B项适合作文章标题。 Ⅱ.阅读七选五 Learning doesn't have to stop at the schoolhouse door.In fact, it shouldn't. __9__ It's one thing to read a book about a foreign country; it's quite another to go there and befriend its people, eat its foods and learn its language. __10__ My husband Gabriel and I use it to engage with our love of history.We can't travel to the past in exactly the same way we would go to a foreign country, but we can bring history to us by including as many of its details as possible into our daily lives. __11__ Our house was built in 1888 and 1889.Very little had been added over the past century — although many things had been removed or replaced.Settling in was a long, slow process of bringing back systems and appliances which would have been standard at the end of the nineteenth century. Years ago, we started collecting everyday items from the past.We love things people like us were interacting with on a daily basis back in the Victorian (维多利亚时代的) era.Most textbook history focuses on extreme cases: politics, war, and great names.We've never been privileged to keep company with kings and presidents in the modern world, so we've always been drawn far more strongly to people we ourselves can relate to.We love simple stories of approachable people. __12__ __13__ When we get them, most are worn out.Some people wouldn't think twice about getting rid of such low­quality items.We fix them up and put them back to the use for which they were originally intended.As we interact with them, they become our teachers. A．The best way to learn about something is to live it. B．This technique can be applied to a variety of subjects. C．By doing so we've created a life which is uniquely beautiful. D．Currently I'm working on a novel set in the 1880s and 1890s. E．Using the things they used helps us connect with their culture. F．The antiques which make up our home are a working collection. G．When people visit our home they say it's like walking into a museum. 语篇解读：本文是一篇夹叙夹议文。文章主要介绍了从旧物中学习历史不失为一种好方法。 9.解析：选A　根据下文中的“it's quite another ...learn its language”可知，学习一些东西的最好方法是亲身体验，故A项衔接下文，符合语境。 10．解析：选B　根据下句“My husband Gabriel ...love of history.”可知，这种亲身体验的方法可以应用到很多学科上，故B项衔接下文，符合语境。 11．解析：选G　根据下文可知，作者他们的房子建于1888年和1889年，在过去的一个世纪里，几乎没有什么东西被添加进老屋。据此可知，参观他们房子的人说他们如同进入了一个博物馆，故G项衔接下文，符合语境。 12．解析：选E　根据空处上文可知，在现代社会，他们无法和国王与总统结交，所以他们寻找的是平易近人的人。据此可知，空处说明其原因：使用他们用过的东西，有助于人们与他们的文化建立联系，故E项承接上文，符合语境。 13．解析：选F　根据该段最后两句“We fix them up ...become our teachers.”可知，作者他们修复了这些旧物并使它们回归原用，这时这些旧物就成了他们学习历史的老师。据此可知，该段主要陈述作者他们家的这些旧物都是有用的，故F项符合本段主旨。 Ⅲ.完形填空 (2024·长沙模拟)One day Christopher Columbus was at a party that a Spanish gentleman gave in his honor.People were saying，“What a great __14__ you have made！” However, several people present were envious of him.They began to try to make Columbus __15__. “You have discovered new __16__ beyond the seas，” they said, “but what of that? Anybody can __17__ across the ocean and anybody can coast along the islands on the other side.It is the __18__ thing in the world.All you need to do is sail west.That's not a(n) __19__ feat (功绩)．” Columbus made no __20__， but after a while he took an egg from a dish and said to the company, “Who among you, gentlemen, can make this egg __21__ on end？” “That's impossible，” the host replied.“You would need to be a __22__ to do that.” One by one, those at the table __23__ the experiment.__24__， none of them succeeded. After a short silence, Columbus took the egg and struck its small end __25__ upon the table so as to __26__ the shell (壳) a little.After that, there was no __27__ in making it stand upright.“Gentlemen，” said he, “what is easier than to do this which you said was impossible? It is the simplest thing in the world.Anybody can do it — AFTER HE HAS BEEN __28__ HOW！” 语篇解读：本文是一篇记叙文。文章讲述了哥伦布竖鸡蛋的故事，告诉我们要勇于实践、敢于创先，由平凡的小事中也能做出非凡的壮举。 14．A.decision　　　　　　　 B．schedule C．discovery D．statement 解析：选C　根据常识可知，哥伦布发现新大陆是一个伟大的发现。 15．A.unhurt B．uncomfortable C．unfortunate D．unafraid 解析：选B　根据空前的内容可知，有些在场的人嫉妒哥伦布，因此他们想方设法使哥伦布感到不自在。 16．A.substances B．oceans C．lands D．treasures 解析：选C　哥伦布发现新大陆是不争的事实。 17．A.sail B．run C．walk D．hike 解析：选A　根据常识可知，要想从大洋中穿过，必须航行过去。 18．A.greatest B．worst C．hardest D．simplest 解析：选D　根据最后一段中的“It is the simplest thing in the world.”可知，此句应指他们认为这是最简单的事情。此处为原词复现。 19．A.small B．useless C．remarkable D．ordinary 解析：选C　根据上文内容可知，他们认为发现新大陆不足为奇，这是世界上最简单的事情，因此这不是什么非凡的壮举。 20．A.apology B．answer C．mistake D．secret 解析：选B　根据下文的“but after a while he took an egg from a dish and said to the company”中的“but”可知，此处应指哥伦布未作回答，但过了一会儿，他从盘子里拿了一个鸡蛋，问了大家一个问题。 21．A.roll B．sit C．fall D．stand 解析：选D　根据空后的“on end”可知，此处指哥伦布的问题是谁能将鸡蛋立起来。 22．A.magician B．sailor C．planner D．doctor 解析：选A　根据语境可知，聚会的主人认为将鸡蛋竖立起来是不可能的事。根据常识可知，他认为要想做到这件事，需要找一个魔术师。 23．A.evaluated B．finished C．tried D．designed 解析：选C　根据语境可知，此处指坐在桌子旁边的人一个挨一个地做这个实验。 24．A.Above all B．At last C．For instance D．In addition 解析：选B　根据语境可知，此处指最终没有一个人成功。 25．A.gently B．helplessly C．heavily D．critically 解析：选A　根据常识可知，鸡蛋要轻轻敲打否则会打碎的。 26．A.find B．change C．hide D．break 解析：选D　哥伦布轻轻敲打鸡蛋的目的是将鸡蛋壳打破一点。 27．A.trouble B．instruction C．reaction D．point 解析：选A　根据上文内容并结合常识可知，将鸡蛋壳打破一点之后，鸡蛋就可以毫不费力地立起来了。There is no trouble in doing sth.为固定句型，意为“做某事毫不费力”。 28．A.HIT B．SHOWN C．EXPLODED D．SET 解析：选B　前面提到，哥伦布通过轻轻敲打将鸡蛋壳打破一点的方式将鸡蛋轻松竖立起来说明一切皆有可能。由此可知，此处指的是任何人都能做到——只要有人教过他怎么做。 学科网（北京）股份有限公司 $$
