Ⅲ.阅读理解(共7小题；每小题2.5分，共17.5分) A (2024·浙江温州高二期末) Many popular modern board games were invented in the United States.But some of our favorite games came from other countries and have deep historic roots. Parcheesi Parcheesi came from India，where it is known as pachisi.The Mogul King Akbar，who ruled India in the 1500s，actually had a life-sized version of pachisi in his garden.Parcheesi came to America around 1870，and now has many variations of it—where each player has four pawns(兵) and races to be the first one to get them all safely to a home base. Checkers Though simpler than Chess，Checkers offers plenty of strategic considerations for its players.Developing from a Middle Eastern game called alquerque，Checkers was introduced to America in the 1930s and has a number of variations that have been played since at least 3000 BCE. Backgammon Backgammon originated in Mesopotamia around 3000 BCE.In the game，two players take turns rolling dice in a race to be the first one to get their 15 pieces off the board.Introduced to America in 1920，Backgammon became wildly popular then and remains so today，especially in its electronic version. Mancala Mancala means “to move” in Arabic.Players take turns to move pieces on its special board until all the pieces have been captured.Ancient game boards dating from the 6th and 7th centuries have been found carved in stone in Ethiopia.Mancala was brought into America in 1940 by immigrants from Cape Verde in Africa.And yes—it is played online! 1．Which of the following was first introduced to America? A．Parcheesi. B．Checkers. C．Backgammon. D．Mancala. 答案　A 解析　细节理解题。根据第二段中的“Parcheesi came to America around 1870”；第三段中的“Checkers was introduced to America in the 1930s”；第四段中的“Introduced to America in 1920”以及最后一段中的“Mancala was brought into America in 1940”可知，Parcheesi最先被引入美国。故选A。 2．What do Backgammon and Mancala have in common? A．Each game has four players. B．They have digital versions. C．Their boards were carved in stone. D．They date back to 3,000 years ago. 答案　B 解析　细节理解题。根据第四段中的“especially in its electronic version”以及最后一段中的“And yes—it is played online！”可知，Backgammon和Mancala的共同之处是都有电子版。故选B。 3．In which column of a magazine can this text be found? A．Health. B．Economy. C．Science. D．Entertain. 答案　D 解析　文章出处题。根据第一段内容并结合文章主要介绍了四款游戏的历史可推知，文章可能选自杂志的“娱乐”版面。故选D。 B If you visit the new “Mummies(木乃伊)” show at the American Museum of Natural History(AMNH)，in New York City，don’t miss the Gilded Lady.Scientists say she probably died of lung disease when she was in her 40s—about 2,000 years ago—in Egypt.They even have a model of her skull(头骨)．Based on that，an artist was sure how she may have looked when she was alive.And yet，the mummy’s coffin has never been opened.Instead，scientists used a machine called a CT scanner(扫描仪) to look inside. CT scanners were developed to help doctors examine patients.But the machines turned out to be perfect for studying mummies，too. “A hundred years ago，scientists would usually open mummies’ coffins.This did a great deal of harm to those mummies，” says AMNH president Ellen V．Futter.“We just don’t do that anymore.We can do so much better.By using CT scanners，scientists can know about an ancient person’s diet from some of a mummy’s hair.Pieces of bone can show who was related to whom.” Some mummies in Peru were buried with a skull hanging from their neck.Scientists thought these mummies wore the skull of an enemy.But DNA evidence showed that the mummies were buried with the skull of an ancestor(祖先)． The 19 mummies in the show are from Egypt and Peru.They had completely different reasons for mummifying the dead.The ancient Egyptians believed that mummification allowed an ancestor to live on in the next world.The people who prepared the Gilded Lady thought she would continue to see，hear，and smell.In ancient Peru，people practiced mummification to stay connected with their ancestors.Some families kept mummies in their home. Futter calls the mummies in the show “messengers from another time”．With the help of technology，scientists will continue to uncover mummies’ secret so we can understand it. 语篇解读　这是一篇说明文。本文通过介绍美国自然历史博物馆展出的来自埃及和秘鲁的木乃伊，指出现代科技在帮助科学家探索木乃伊的秘密上发挥的重要作用。 4．What did scientists find about the Gilded Lady? A．She was a great artist. B．She died a natural death. C．She lived in ancient Egypt. D．She had an amazingly long life. 答案　C 解析　细节理解题。根据第一段中“Scientists say she probably died of lung disease when she was in her 40s—about 2,000 years ago—in Egypt.”可知，科学家发现她生活在两千年前的古埃及，故选C。 5．What do Futter’s words suggest? A．Pieces of bone show a person’s diet. B．CT scanners do great harm to mummies. C．Mummies usually wore the skull of an enemy. D．Technology plays an important role in mummy studies. 答案　D 解析　推理判断题。根据第三段中“By using CT scanners，scientists can know about an ancient person’s diet from some of a mummy’s hair.Pieces of bone can show who was related to whom.”可知，Futter指出科技在研究木乃伊中起到重要作用，故选D。 6．Why did the ancient Peruvians make mummies? A．To do traditional medical research. B．To keep close ties with their relatives. C．To help their families live a better life. D．To let their ancestors live in another world. 答案　B 解析　细节理解题。根据倒数第二段中“In ancient Peru，people practiced mummification to stay connected with their ancestors.”可知，古代秘鲁人制作木乃伊是为了和自己的祖先保持联系，故选B。 7．What does the underlined word “it” in the last paragraph refer to? A．The technology. B．The message. C．Their family. D．The show. 答案　B 解析　代词指代题。根据最后一段可知，Futter称展览中的木乃伊是另一个时代的信使，在科技的帮助下，科学家会继续揭示木乃伊的秘密以便我们更好地理解它们传递的信息，故选B。 Ⅳ.七选五(共5小题；每小题2.5分，共12.5分) Overcoming Fear of Failure Have you ever been so afraid of failing at something that you decided not to try at all? Or has fear of failure meant that，subconsciously，you undermined(逐渐削弱) your own efforts to avoid the possibility of a larger failure？ 1 It’s important to realize that in everything we do，there’s always a chance that we’ll fail.Facing that chance and embracing it give us a more rewarding life.Here are a few ways to reduce the fear of failing. Analyze all potential outcomes. 2 Remove that fear by considering all of the potential outcomes of your decision.You can map possible outcomes visually. Set small goals.Imagining how life will be after you’ve reached your goal is a great motivator to keep you moving forward.So start by setting a few small goals. 3 Don’t focus on the end picture.Just focus on the next step.Taking one small step at a time will help build your confidence and keep you moving towards your final goal. Learn to think more positively.Every coin has two sides. 4 Learn to change your thoughts and focus more on the bright side of the situation，making you like yourself.Positive thinking is an incredibly powerful way to build self-confidence. 5 In some cases，the toughest situation may be genuinely disastrous(灾难性的) and it may be perfectly reasonable to fear failure.In other cases，however，this worst case may actually not be that bad，and recognizing this can help. A．Look at the worse-case situation. B．It is up to you to decide which one to look at. C．Failing at something can help you discover your truest friends. D．Many of us have probably experienced this at one time or another. E．If you are afraid of failure，you might be uncomfortable setting goals. F．These should be goals that are slightly，but not overwhelmingly，challenging. G．Many people experience fear of failure because they fear the unknown. 1．答案　D 解析　上文“Have you ever been so afraid of failing at something that you decided not to try at all？...larger failure？”讲述了人们害怕失败的两种心理状态，再结合下文“It’s important to realize that in everything we do，there’s always a chance that we’ll fail.”可知，该空应该讲许多人可能都经历过这两种心理状态，D选项切合语境，故选D项。 2．答案　G 解析　由本段主旨句“Analyze all potential outcomes.”可知本段主要讲减少人们对失败的恐惧的方法之一——分析事情将产生的所有(好坏)结果，结合本段下文可知，该空应该要分析人们害怕失败的原因——对未知结果的恐惧，G选项切合语境。故选G项。 3．答案　F 解析　由本段主旨句“Set small goals.”可知本段主要讲减少人们对失败的恐惧的另一个方法——设定小目标，再结合上文“So start by setting a few small goals.”可知，该空应该讲具体如何设置小目标，F选项切合语境。故选F项。 4．答案　B 解析　由本段主旨句“Learn to think more positively.”可知本段主要讲第三个方法——学会更积极地思考，再结合上文“Every coin has two sides.”可知，该空应该讲积极思考事物两面性后应该怎么做，B选项切合语境。故选B项。 5．答案　A 解析　该空为本段主旨句，需总结下文。由下文“In some cases，the toughest situation may be genuinely disastrous...and recognizing this can help.”可知，本段在谈论最坏的情况，A选项“看看更糟糕的情况”切合语境。故选A项。 Ⅴ.语法填空(共10小题；每小题1.5分，共15分) (2024·山东菏泽高二下期末) In Chinese culture，long noodles are thought to symbolize long life，which 1.

In northern China，noodles are a popular Lunar New Year custom，where the traditional custom is 2.
