My handiwork wasn't beautiful.But what I remember is the beauty of the offering：slipping something into a friend's hand and knowing it would always be with them.The experience was intoxicating — like the serious business of exchanging wedding rings，it was a symbol of an unbreakable bond.Those bracelets represented how much we meant to each other, at a time when our friends were becoming the center of our lives. I slept with my bracelets and showered with them.I wore them all summer long at camp.And I acquired new bracelets from friends there — friends who received carefully crafted bracelets from me in return，as we said our tearful end-of-summer goodbyes.I thought having them helped ease the pain of leaving my friends.But now I see that they were really helping me to leave behind childhood. My kids don't go to summer camp.They certainly don't exchange anything as uncool as bracelets with their friends.They hang out on social media in chats that only pause but never end.Our eldest son endlessly texts on his cellphone as he and his friends make one another talking emojis and videos. Their relationships with their phones leave no time or space for writing letters or making bracelets, and their gifts to one another leave no clear and definite traces.There will be no boxes of letters to sort years from now nor any hidden bracelets to find.They will have little to physically hold on to. 语篇解读：本文是一篇夹叙夹议文。作者发现了一条手链，这唤起了她童年时和朋友们交换礼物的回忆。作者觉得如今手机等电子设备的出现，让孩子们沉浸于虚拟世界和聊天软件，从而失去了过去这种充满情意的交流方式。 √ 1．Why does the author compare a bracelet to a time capsule? A．It is faded and worn. B．It is shaped like a capsule. C．It reminds her of her childhood. D．It was made by the author herself. 解析：细节理解题。根据第一段中“Faded and worn, it was a friendship bracelet (手链) — an important part of my teenage summers ... memories of childhood”可知，这串手链与作者的童年有着重要的联系，所以作者把手链比作时间胶囊。 √ 2．Which of the following words can best replace the underlined word “intoxicating” in paragraph 2? A．Exciting.　　　　　　 B．Terrible. C．Professional. 　 D．Strange. 解析：词义猜测题。根据画线词前面两句“My handiwork wasn't beautiful.But what I remember is the beauty of the offering ...”和后半句“like the serious business ...an unbreakable bond”可知，作者的手工艺品并不是很美，但是当把它送给朋友时意义变得深刻，所以这样的体验是令人兴奋的。由此推知，画线词intoxicating意为“令人兴奋的”。 √ 3．Why does the author think her kids' childhood is different from hers? A．They often send hand-made gifts to their friends. B．They make more friends at summer camp. C．They are unwilling to give bracelets to parents. D．They spend too much time on their cellphones. 解析：细节理解题。根据倒数第二段提到的“They hang out on ...friends make one another talking emojis and videos.”可知，作者之所以认为她孩子的童年与自己的不一样是因为现在的孩子们花在手机上的时间太多了。 4．What can be implied about the friendship bracelets? A．They proved the author's kids had much to physically hold on to. B．They gave meaning to the author's childhood in a way her kids will never know firsthand. C．They represented both the author and her kids' unforgettable childhood. D．They recalled the author's deep sorrow of leaving close friends at summer camp. √ 解析：推理判断题。根据最后一段内容可知，代表友谊的手链只有作者有，她的孩子没有。手链让作者想起了美好的童年经历，而这种感受是当今的孩子们无法体会的，因为他们大多数沉浸在虚拟世界中。因此，她的孩子们永远体会不到手链给作者的童年赋予的意义。 (二)完形填空 For the past 18 years, my daughter has been around me all the time. Now that she is in college, the 5 of our relationship has totally changed and our relationship is completely 6 . I'm not going to be there every morning to have breakfast with her. I won't know when she's mad or when she's happy. Here's a little story of our new 7 . A week ago, my daughter wanted to 8 so she called me during the day as I was in meetings. I 9 her later on, but she was in class. At midnight, she reached out 10 to ask if we could talk. Well, guess what? I was 11 . I thought we would talk the next day, but she was not 12 . Research shows that parents are 13 when their children are grown up, but for me that is when I start to get concerned. I am always left to 14 ， how can I, as a parent, remain 15 to my daughter to guide, support and love her through life's changes? We may have to 16 the way we communicate. My daughter encouraged me to go digital. That's how I ventured into the world of social media, following her updates and occasionally sharing my own experiences. Through this 17 presence, the physical gap is 18 and I feel I still have an active role in her life. This experience serves as a reminder that 19 , however scary, holds the promise of growth in our shared journey. 语篇解读：本文是一篇记叙文。女儿上大学后，作者与女儿的关系发生了变化，作者开始感到不安。在女儿的鼓励下，作者通过使用社交媒体重拾了与女儿的关系。通过这次经历，作者意识到无论变化多么可怕，它都承载着成长的希望。 √ 5．A.problem　　　　　　 B．progress C．goal 　 D．context 解析：在过去的18年里，作者的女儿一直在作者身边，而现在她上大学了。由此可知，作者与女儿的关系背景完全改变了。 6．A.cold 　 B．special C．different 　 D．casual 解析：上文讲“作者与女儿的关系背景完全改变了”；下文讲“作者现在不能每天早上和女儿一起吃早餐，也不知道她什么时候生气、什么时候开心”。由此可知，作者和女儿的关系也完全不同(different)了。 √ 7．A.normal 　 B．idea C．approach 　 D．solution 解析：根据第二段的描述可知，作者讲述了一个关于自己与女儿相处的新常态的小故事。normal在此作名词，意为“常态”。 √ 8．A.catch up 　 B．take over C．check out 　 D．break away 解析：根据空后的“she called me”并结合常识可知，女儿想了解作者近期的动态，所以给作者打电话。 √ 9．A.visited 　 B．touched C．tried 　 D．emailed 解析：上文讲女儿给作者打电话时，作者正在开会。由此可推知，作者过后试图联系女儿。 √ 10．A.by taxi 　 B．by text C．in private 　 D．in person 解析：根据上文的“At midnight”并结合常识可推知，女儿在午夜给作者发短信问是否可以谈一谈。 √ 11．A.stupid 　 B．angry C．excited 　 D．asleep 解析：根据上文“At midnight”和下文“I thought we would talk the next day”可推知，女儿给作者发短信时，作者已经睡着了。 √ 12．A.available 　 B．interested C．ready 　 D．guilty 解析：根据上文“I thought we would talk the next day” 和 but表示转折关系可推知，作者想第二天再和女儿交流，但是女儿没空。available“有空的”；guilty“内疚的”。 √ 13．A.saddest 　 B．busiest C．happiest 　 D．best 解析：根据下文“but for me that is when I start to get concerned”可知，空处描述的状态与下文的“concerned”相反。再结合常识可知，当孩子长大时，父母是最高兴的。 √ 14．A.decide 　 B．wonder C．investigate 　 D．distinguish 解析：根据上文“I start to get concerned”和下文“how can I ...changes”可知，作者开始感到不安，总是在想：作为父母，在生活发生变化时如何始终与女儿保持联系，引导、支持并关爱她。 √ 15．A.kind 　 B．appreciative C．sensitive 　 D．relevant 解析：此处呼应第一段中的“For the past 18 years, my daughter has been around me all the time”，表示作者想知道在女儿上大学的情况下，自己如何才能像过去的18年里一样，一直和女儿紧密相连。 √ 16．A.voice 　 B．ignore C．shift 　 D．continue 解析：根据下文“My daughter encouraged me to go digital ...sharing my own experiences”可知，作者开始改变自己和女儿之间的交流方式。 √ 17．A.human 　 B．virtual C．physical 　 D．permanent 解析：根据上文可知，作者开始进入社交媒体的世界，关注女儿的动态，偶尔分享自己的经历。由此可知，作者通过这种虚拟的存在，弥合了现实中的距离，觉得自己仍然在女儿的生活中扮演着积极的角色。 √ 18．A.widened 　 B．formed C．broken 　 D．bridged 解析：作者通过这种虚拟的存在，弥合了现实中的距离，觉得自己仍然在女儿的生活中扮演着积极的角色。widen“(使)变宽”；form“(使)形成”；bridge“弥合(差异)，消除(分歧)”。 √ 19．A.college 　 B．relationship C．change 　 D．communication 解析：通读全文可知，作者通过改变与女儿的交流方式重拾了与女儿的关系。所以作者通过这次经历，意识到无论变化(change)多么可怕，它都承载着成长的希望。 √ (三)语法填空(15分) Life in the 2050s will be different from what it is now, because many changes will take place. What will the changes be? The population 20 (grow) fast now. There will be too many people 21 (live) in the world by 2050. Some people will go to the moon and other planets. They can travel to Mars and back 22 just three days. Computers will be much smaller and 23 (use) more widely, and there will be at least one in every home. And computer study will be one of the popular 24 (subject) in schools. People will work fewer hours than we do now 25 they will have more free time for sports, TV and traveling. Traveling will be much cheaper and 26 (easy). And many people will go to other countries for holiday. There will be changes in our food, too. Because more and more people know the 27 (important) of healthy diet. Maybe they will eat less meat but more vegetables and fruit. So people will be healthier. Work in the future will be different, too. 28 (danger) and hard work will be done by robots. We will have robots to help clean, cook and do our home shopping, because of 29 many people won't have enough work to do. This will be a problem. 语篇解读：本文是一篇说明文。文章主要设想21世纪50年代生活的样子，它将不同于现在的生活。 20．is growing　考查动词时态和主谓一致。根据时间状语now可知，描述正在发生的事情，所以用现在进行时态，主语population为不可数名词，所以be动词为is。故填is growing。 21．living　考查非谓语动词。句中已有谓语动词，所以空处用非谓语动词形式。live和它所修饰的词people之间是主动关系，所以用现在分词作后置定语。故填living。 22．within　考查介词。此处表示“在……之内”，后跟名词，所以用介词within。 23．be used　考查动词语态。use和主语Computers之间是被动关系，所以用被动语态，前面有will，所以用动词原形。故填be used。 24．subjects　考查名词复数。前面有one of，所以用名词复数。故填subjects。 25．but　考查连词。前后是转折关系，所以用转折连词but连接。故填but。 26．easier　考查形容词比较级。和cheaper并列，所以用形容词比较级形式作表语。故填easier。 27．importance　考查名词。作宾语，所以用名词importance，其为不可数名词。 28．Dangerous　考查形容词。作定语修饰名词work，所以用形容词，位于句首，单词首字母应大写。故填Dangerous。 29．which　考查非限制性定语从句。此处指代前面句子，在非限制性定语从句中作介词的宾语，所以用关系代词which引导。 (四)主题微写作(15分) [教材原句] 　A bunch of us kids would frequently drop by the store after school. We'd look at the new books, or just chat with Old Casey. He knew every book in the store and would always pick the perfect one for us from a dusty shelf. We spent hours reading, seated on the store's old but comfortable furniture. [分析]　这段文字运用了一系列的动作描写，如drop by, look at, chat with, pick, spent hours reading等，生动地再现了孩子们在书店里的日常活动场景。这些动作描写不仅展现了孩子们对书店的喜爱和依赖，也体现了老凯西对孩子们的关爱和对书店经营的用心，使读者能够感受到书店曾经充满活力和温馨的氛围，增强了文章的感染力。 [仿写]　在篮球场上，球员们会在球场上飞奔，熟练地运球，然后把球传给队友。教练会站在边线，吹响哨子，快速打手势指挥球员们的动作。 参考范文： In the basketball court, the players would run quickly across the floor, handle the ball skillfully, and throw it to their teammates. The coach would stand on the sidelines, blow the whistle, and make fast hand movements to guide the players' actions. 本课结束 更多精彩内容请登录：www.zghkt.cn $
