As we were eating our pepper and salt tofu, a young lady named Debra walked in. She wasn't aware that the place is vegan and was looking for some meat. My wife and I talked up the place and invited her over to try some of our tofu. Debra tried it, nodded and went out.‎ After a few minutes, she and her mother both walked back in. We were having the rest of our meal at that time, so we told her what we had ordered. Debra then asked the waitress to just repeat our order for them. Next, Debra said，“And we want to pay for their meal”， pointing to my wife and me. We tried to say no, but Debra wouldn't listen.‎ That was not the end of it. Hugs were in order. Debra came over to our table and my wife got up to hug her. Debra hugged my wife and put $100 into her hand. My wife firmly said NO, but Debra insisted. Debra kept talking about our kindness, and we did the same about hers and her mother's. With tears in the eyes, the workers were blown away by this whole exchange between four strangers. I left the waiters and waitresses a tip that would cover all of our meals and we were on our way.‎ I've been witnessing so much kindness, especially over the last few years, as I began to pay more attention. We now have a new favorite restaurant and every time we go there my plan is to pay for someone else's meal.‎ ‎4．Why did Debra go out after trying some tofu?‎ A．To bring her mother in.‎ B．To look after her mother.‎ C．To get away from the food.‎ D．To look for another restaurant.‎ ‎5．What did Debra insist on?‎ A．Hugging the author's wife.‎ B．Ordering a meal for the author.‎ C．Treating the author and his wife.‎ D．Tipping the waiters and waitresses.‎ ‎6．How did the workers feel when seeing the exchange between four strangers?‎ ‎　‎ A．Curious.

Freeloaders, they just sit around while their hardworking colleagues get things done. But might freeloaders actually be necessary for society to function efficiently? The answer could be yes — at least when it comes to fire ants and their efforts to dig nests underground.‎ Fire ants are highly social organisms. So, Goldman and his colleagues wanted to know how individual ants knew what to do without a central leader issuing orders. To find out, Goldman's team labeled individual fire ants with paint and then watched them dig their tunnels — only wide enough for two workers. It turned out that just 30 percent of the ants did 70 percent of the labor，“I was surprised that we ended up with so few workers actually doing the work at any one time.”‎ A quarter of the ants never even entered the tunnel. Others went inside, but left without digging out a single grain of dirt. These behaviors ensured the tunnels did not getclogged with insect traffic, which would make the construction process stop.‎ And when the scientists removed the five hardestworking ants from the tunnel, others immediately jumped in to compensate (补偿) — with no reduction in the group's productivity. It ‎ seems that it doesn't matter which ants are working or freeloading at a given time, as long as there is some division of labor to keep the tunnels flowing smoothly. The findings are in the journal Science.‎ The study could provide suggestions for the robotics. Imagine groups of robots sent to search for survivors from the ruins, or nanobots (微型机器人) coursing through our bodies to diagnose illness and deliver targeted medical treatment. Such robots will need to avoid getting jammed up in tight spaces. It might be necessary to program them so some just sit back and watch their colleagues work.‎ ‎8．How do fire ants get the work done when digging tunnels?‎ A．They all work under the order of their leaders.‎ B．Only the strong ants do the majority of the work.‎ C．They all cooperate together and spare no effort to do the work.‎ D．Some work efficiently while others just sit around and do nothing.‎ ‎9．What does the underlined word “clogged” in Paragraph 3 probably mean?‎ A．Covered. B．Crowded.‎ C．Destroyed. D．Spotted.‎ ‎10．When the hardestworking ants were taken away by the scientists, ________.‎ A．the rest of them didn't know what to do B．the leaders had to do the work by themselves C．other ants took their place and continued to do the work D．other ants were in panic and escaped from the tunnel immediately ‎11．According to the passage, the research findings can be applied to ________.‎ A．robot technology ‎ B．social communication C．underground construction ‎ D．scientific observations D ‎[2020·重庆第一次调研]A shirt, tie and blazer may not be my favorite, but if I were given the choice, I wouldn't throw away the idea of school uniform. Wearing a uniform is a badge of pride, creates an identity for a school and is an important part of being a school student.‎ My school is one of many that seem to be shifting to a more formal uniform — this September I will be wearing a shirt and blazer instead of my old jumper and polo shirt. A number of students have complained about the change, but some people believe that a school uniform can improve learning by reducing distraction, sharpening focus on schoolwork and making the classroom a more serious environment, allowing students to perform better academically. Perhaps most importantly, a uniform means students don't have to worry about peer pressure when it comes to their clothes. When everyone is dressed the same, worrying about what you look like isn't so important. There is no competition about being dressed in the latest trend, which would put a great deal of financial pressure on students and parents. Potential bullies have one less target for their insults; it's hard to make fun of what someone is wearing when you're dressed exactly the same.‎ In America, where a majority of schools do not have a uniform, roughly 160,000 children miss school every day due to fear of attack or intimidation by other students. This might not be directly linked to what they're wearing, but having a uniform can be a safety net for many students who might otherwise suffer from bullying. A uniform gives the impression that rules are strict, perhaps helping maintain a sense of order at school.‎ My uniform might not be what I would wear in my own time, but it gives me a sense of belonging, takes away the pressure of what to wear and stops the bullies. School uniform isn't fashionable, but that's exactly why I think it should be here to stay.‎ ‎12．Why does the writer mention American children without uniforms in the passage?‎ A．To show pity for American kids.‎ B．To raise the government's attention.‎ C．To prove the benefits of school uniform.‎ D．To inform readers of American kids' uniforms.‎ ‎13．What is the writer's attitude towards school uniforms?‎ A．Disapproving. B．Confused.‎ C．Suspicious. D．Favorable. ‎ ‎14．Which is the advantage of wearing school uniforms for school kids?‎ A．It sharpens concentration on outdoor tasks.‎ B．It removes the teachers' financial pressure.‎ C．It satisfies students' dressing tastes and favorites.‎ D．It helps students maintain a sense of order at school.‎ ‎15．What is the best title for the passage?‎ A．My Cool School Uniform B．The Point of School Uniform C．The Idea of Dressing Properly D．The Way of Guarding Kids' Safety 第二节　(共5小题；每小题2分，满分10分)‎ 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。‎ ‎[2019·成都第二次诊断]Twentyfive years of experience in the field have convinced me that many people who consider themselves to be highly intelligent are not necessarily good thinkers. __1__ There are many aspects of this trap but I shall mention just two.‎ A highly intelligent person can take a view on a subject and then use his or her intelligence to defend that view. __2__ When a person has a better defence of the view, he or she is less likely to seek out alternatives or listen to anyone else. __3__ As a result, many highly intelligent minds are trapped in poor ideas because they can defend them so well.‎ A second aspect of the intelligence trap is that a person, who has grown up with the notion that he or she is more intelligent than those around, wants to get the most satisfaction from that intelligence. __4__ Such a strategy gives you an immediate result and also establishes your superiority. Being constructive is much less rewarding. It may take years to show that a new idea works. __5__ So it is obvious that being critical and destructive is a much more appealing use of intelligence. This is made even worse by the absurd Western notion that critical thinking is enough.‎ A．They get caught in the intelligence trap.‎ B．But why are intelligent people not good thinkers?‎ C．Intelligent people always enjoy arguing with others.‎ D．You also have to depend on the listener liking your idea.‎ E．A person with higher intelligence always defends one's view better.‎ F．The quickest and most reliable way is to prove someone else wrong.‎ G．If you know that you are right, why should you do either of those things?‎ ‎课时练(二)　语言知识运用·组块专练——练准度 ‎(限时：30分钟)‎ 语言知识运用(共两节，满分45分)‎ 第一节　完形填空(共20小题；每小题1.5分，满分30分)‎ 阅读下面短文，从短文后各题所给的四个选项(A、B、C和D)中，选出可以填入空白处的最佳选项。‎ ‎[2019·新疆第二次适应性测试]What I have learned with my three teens is this: when they are testing me and pushing the limits in a way that feels more aggressive than normal teenage behavior, this is when they need some extra love and __1__.‎ When our kids are young and aren't able to __2__ how they are feeling, they typically behave in a way that makes it obvious that they are sad, __3__， or not feeling like themselves. We parents try __4__ to help them feel better, whatever it __5__. We won't __6__ even though we can't quite understand.‎ As they get __7__ and are able to talk and communicate, I think we raise our expectations a little bit too __8__ — I've realized although they can talk and communicate and let us __9__ whether something is wrong, it doesn't mean they will.‎ Not because they don't always want to, __10__ teenagers seem to think they can __11__ it on their own; they think their __12__ won't understand, or they are too embarrassed to come to us with their __13__ or talk about certain situations. But I've also had to realize when my teens are disrespectful, they might not know how to __14__ themselves. Even as a 43yearold woman I still __15__ with finding the words or putting a name to my feelings. I mean my teens need me to __16__ them to tell me what's wrong.‎ Teens, like all of us are looking for bonding, so make sure we are __17__ time with them. This has to be face to face. If connecting with your teen by text messages feels easier, then start there, but don't __18__ there. Put down your __19__ and look at your teen in the eyes to communicate too, and __20__ will take you and your teen's relationship to another level.‎ ‎　‎ ‎1．A.complaint B．punishment C．praise D．attention ‎2．A.sing B．explore C．communicate D．build ‎3．A.uncomfortable B．delighted C．excited D．energetic ‎4．A.something B．everything C．nothing D．anything ‎5．A.offers B．takes C．makes D．calls ‎6．A.give in B．give up C．give off D．give out ‎7．A.smaller B．stronger C．older D．younger ‎8．A.high B．low C．fast D．slow ‎9．A.ask B．say C．debate D．know ‎10．A.because B．since C．though D．but ‎11．A.handle B．hide C．present D．expose ‎12．A.friends B．parents C．teachers D．teammates ‎13．A.worries B．possibilities C．explanations D．assumptions ‎14．A.push B．determine C．express D．urge ‎15．A.argue B．work C．struggle D．dream ‎16．A.force B．encourage C．refuse D．forbid ‎17．A.wasting B．killing C．spending D．losing ‎18．A.stand B．hang C．leave D．stop ‎19．A.magazines B．newspapers C．books D．phones ‎20．A.connections B．adjustment C．service D．disappointment 第二节　(共10小题；每小题1.5分，满分15分)‎ 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。‎ ‎[2020·潍坊高考模拟]The Hong KongZhuhaiMacau Bridge (HZMB), a 55kilometer bridgetunnel system, __1__ (consist) of a series of three cablestayed bridges, an undersea tunnel, and four artificial islands.

We tried to say no, but Debra wouldn't listen”和第三段中的“Debra hugged my wife... but Debra insisted”可知，Debra坚持要为作者夫妇买单。‎ ‎6．D　考查推理判断。根据第三段中的“With tears in the eyes, the workers were blown away... between four strangers”信息可知，餐厅的服务员看到这一幕，他们眼睛都湿润了，说明他们很感动。‎ ‎7．C　考查细节理解。根据第三段中的“between four strangers”信息可知，作者夫妇与Debra和Debra的妈妈是第一次见面，由此可知本题选C。‎ ‎【语篇解读】　本文是一篇说明文。研究发现，火蚁群体的生产力高，在建穴过程中，只有极少部分的火蚁参加完成大部分的工作，而其他火蚁不作为。这一发现可以应用于机器人技术。‎ ‎8．D　考查细节理解。根据第一段第一、二句“Fire ants tunnels got dug efficiently by only a small percentage of the group doing most of the work. Freeloaders, they just sit around while their hardworking ‎ colleagues get things done”可知，火蚁的大部分建巢工作都是由一小部分蚁群来完成的，但挖掘效率却很高；其他的火蚁却什么都不做，故D项正确。‎ ‎9．B　考查词义猜测。根据第三段第二句“Others went inside, but left without digging out a single grain of dirt”可知，其他蚂蚁进去了，但没有挖出一粒泥土就离开了；结合该段第三句中的“which would make the construction process stop”可知，这样的举动可能会使工作停止；据此可推知，该处表示这些行为能确保洞穴不发生交通堵塞，故画线词意为“堵塞”，故B项正确。‎ ‎10．C　考查细节理解。根据第四段第一句“And when the scientists removed the five hardestworking ants from the tunnel, others immediately jumped in to compensate (补偿) — with no reduction in the group's productivity”可知，当科学家们把五只工作最勤奋的蚂蚁移开时，其他蚂蚁就会立刻来补偿，组织的生产力没有减少，故C项正确。‎ ‎11．A　考查细节理解。根据尾段的内容尤其是第一句“The study could provide suggestions for the robotics”可知，这一研究成果可以应用于机器人技术，故A项正确。‎ ‎【语篇解读】　本文是一篇议论文。在学校“我”选择穿校服，因为校服是学校的标志，学生统一穿校服能使教室成为严肃的场所，让学生更加专注于学习；此外，穿校服还能减少校园欺凌事件的发生。‎ ‎12．C　考查推理判断。根据第三段的内容可知，在美国，大多数学校没有统一的校服，每天大约有16万名儿童因为害怕受到其他学生的攻击或恐吓而缺课。这可能与他们的穿着没有直接的联系，但是对于许多可能遭受欺凌的学生来说，校服是一种保护措施，而且也帮助维持了学校的秩序。据此可推知，作者在此提及美国儿童没有穿统一的校服旨在说明校服的好处，故C项正确。‎ ‎13．D　考查推理判断。根据尾段中的“it gives me a sense of belonging, takes away the pressure of what to wear and stops the bullies. School uniform isn't fashionable, but that's exactly why I think it should be here to stay”可知，“我”的校服给了“我”一种归属感，消除了穿什么衣服的压力，阻止了那些欺负我的人；虽然校服并不时尚，但这正是“我”认为它应该留在这里的原因。据此可推知，作者对校服持赞同的态度，故D项正确。‎ ‎14．D　考查细节理解。根据第三段最后一句“A uniform gives ‎ the impression that rules are strict, perhaps helping maintain a sense of order at school”可知，校服也会给人留下规章制度严格的印象，有助于维持学校的秩序，故D项正确。‎ ‎15．B　考查主旨大意。通读全文可知，在学校里“我”选择穿校服，因为校服是学校的标志，学生统一穿校服能使教室成为严肃的场所，让学生更加专注于学习；此外，穿校服还能减少校园欺凌事件的发生。故B项最适合作本文的标题。‎ 第二节 ‎【语篇解读】　本文是一篇说明文，主要介绍了两个常见的高智商误区。‎ ‎1．A　承接上文中的“highly intelligent”并和空后一句中的“trap”呼应可推知，自以为高智商的人会陷入智商误区，故选A项。‎ ‎2．E　根据空前一句“A highly intelligent person can take a view on a subject and then use his or her intelligence to defend that view”可知，高智商的人会更好地维护自己的观点，与下文中的“When a person has a better defence of the view”呼应，故选E项。‎ ‎3．G　根据空前的“he or she is less likely to seek out alternatives or listen to anyone else”可知，当一个人能更好地维护自己的观点时，其就不会去找其他方法或去聆听别人，故G项符合语境。‎ ‎4．F　根据空后一句“Such a strategy gives you an immediate result and also establishes your superiority”可推知，这种策略立竿见影，与选项F中的“The quickest and most reliable way”呼应，故F项符合语境。‎ ‎5．D　根据空后的“So”可推知，空处与空前一句“It may take years to show that a new idea works”为顺承关系，继续说明建设性观点的劣势所在，故选D项。‎ 课时练(二)‎ 语言知识运用 第一节 ‎【语篇解读】‎ ‎　本文是一篇说明文。孩子小的时候，他们不能向父母表达自己的感受，就会通过明显的方式来表达自己的难过或不舒服，当他们长大时，他们又不愿意表达自己的感受。因此，父母要关注孩子的成长，及时有效地和孩子沟通。‎ ‎1．D　根据语境和前面的“when they need some extra love and”可知，此处表示当他们需要特别的爱和关注时，故选D项。‎ ‎2．C　根据语境可知，当孩子小的时候，他们不能表达自己的感受。communicate“传达；传递”，故选C项。‎ ‎3．A　根据该句中的“they are sad, __3__， or not feeling like themselves”，并结合语境可知，此处表示他们伤心、不舒服，故选A项。‎ ‎4．B　根据后面的“whatever it __5__”可知，我们父母尽一切可能去帮助他们感觉好些，无论付出什么，故选B项。‎ ‎5．B　参见上题解析，选B项。‎ ‎6．B　根据下文的“even though we can't quite understand”可知，尽管我们不是很明白，但我们不会放弃，故选B项。‎ ‎7．C　根据下文的“are able to talk and communicate”可推知，当他们年龄大一点时，他们能表达和交流，故选C项。‎ ‎8．A　根据前面的“we raise our expectations”并结合语境可知，此处表示我们把期望提得有点过高，故选A项。‎ ‎9．D　根据语境可知，他们能表达和交流，能让我们知道是否事情出了差错，故选D项。‎ ‎10．D　根据上文“Not because they don't always want to”和下文的“teenagers seem to think they can __11__ it on their own”可知，空处表转折，此处表示并不是因为他们不想，而是青少年认为他们能自己应付它，故选D项。‎ ‎11．A　参见上题解析，故选A项。‎ ‎12．B　根据语境可知，他们认为他们的父母不会理解，故选B项。‎ ‎13．A　根据该句中的“they are too embarrassed to come to us with their __13__”可知，他们羞于带着担忧找父母，故选A项。‎ ‎14．C　根据语境可知，他们也许不知道怎样表达自己，故选C项。‎ ‎15．C　根据上文可知，孩子们也许不知道怎样表达自己，并结合该句可知，作为一个43岁的成人，找到合适的话语表达自己的感受对“我”来说仍然很难，故选C项。‎ ‎16．B　根据语境可知，此处表示“我的意思是孩子们需要我鼓励他们告诉我出了什么差错”，故选B项。‎ ‎17．C　根据该句中的“we are __17__ time with them”可知，此处表示确保花费时间和他们在一起，故选C项。‎ ‎18．D　根据该句“If connecting with your teen... don't __18__ there”可知，如果用手机信息和你的孩子沟通感觉更简单，就从那儿开始，但不能停留在手机交流上，故选D项。‎ ‎19．D　根据上文用手机短信和孩子沟通可知，此处表示放下你的手机，看着孩子的眼睛进行沟通，故选D项。‎ ‎20．A　根据下文的“take you and your teen's relationship to another level”可知，联系能让你和孩子的关系更加深一层，故选A项。‎ 第二节 ‎【语篇解读】　本文是一篇说明文，介绍了港珠澳大桥的构成、造价以及开通时间等。‎ ‎1．consists　考查动词的时态。句意：港珠澳大桥，是一座55千米的桥隧工程桥，由三座斜拉桥、一条海底隧道和四个人工岛屿组成。此处介绍的是港珠澳大桥的组成，属于对事物的客观描述，应用一般现在时；分析句子结构可知，该空作谓语，主语为“The Hong KongZhuhaiMacau Bridge (HZMB)”，谓语动词应为单数，主语与consist是主动关系，故填consists。‎ ‎2．significant　考查形容词。句意：它既是地球上最长的跨海大桥，又是最长的海洋固定运输通道，是另外一个意义重大的工程。设空处修饰名词project，应用形容词，故填significant。‎ ‎3．which　考查定语从句。句意：连接了珠江三角洲的三大主要城市香港、澳门和珠海的港珠澳大桥，跨越了伶仃洋和九洲洋。设空处引导非限制性定语从句，先行词为The HZMB，指物，故填which。‎ ‎4．to last　考查非谓语动词。句意：设计寿命长达120年的港珠澳大桥花费了1 269亿人民币才被建成。be designed to do sth.固定短语“被设计来做某事”，故填to last。‎ ‎5．constructing　考查非谓语动词。句意：建设主体大桥的费用估计为511亿元……。由空前的of可知，设空处应填名词或动名词形式，再由空后作宾语的“the Main Bridge”可知，此处只能用动名词形式，故填constructing。‎ ‎6．to/at　考查介词。句意见上一题解析。be estimated to/at...固定短语“估计为……”，故填to/at。‎ ‎7．Initially　考查副词。句意：最初准备在2016年底通行的大桥最终于2018年2月6日完工，随后记者们乘车经过大桥。设空处后的“set to be opened to traffic”属于分词作状语，修饰状语时应用副词，故填Initially。注意首字母大写。‎ ‎8．journalists　考查名词的数。句意见上一题解析。journalist意为“记者”，是可数名词，设空处后的谓语动词是were，此处应用复数形式，故填journalists。‎ ‎9．the　考查冠词。句意：2018年10月24日，在开幕式之后，港珠澳大桥向公众们开放……“the＋形容词”表示一类人，故填the。‎ ‎10．earlier　考查形容词。a day earlier表示“提前一天”，故填earlier。‎ 课时练(三)‎ 写作 第一节　短文改错 To increase the of protecting the environment, last Saturday we, some volunteers, carried out environmental protection activity in the Civil Square.‎ In the morning, we gathered at the school gate at 7：00.

It was getting late we knew it and the square looked more . as I was, I was very happy because we did do something to protect the environment.‎ ‎①aware改为awareness　此处意为“‎ 为了增强保护环境的意识”，根据前面的the和后面的of可知，此处应用aware的名词形式，故将aware改为awareness。‎ ‎②在environmental前加an　此处泛指“一次环境保护活动”，且后面的activity是单数，故在environmental前加an，因为environmental的发音以元音音素开头。‎ ‎③删除have　这次活动的时间为上文提到的“last Saturday”，所以“In the morning”是指上周六的早上，是表示过去的时间状语，应用一般过去时，故删除have。‎ ‎④when改为where　此处是定语从句，先行词为the square，从句中缺地点状语，故将when改为where。‎ ‎⑤rubbishes改为rubbish　rubbish意为“垃圾”，是不可数名词，故将rubbishes改为rubbish。‎ ‎⑥another改为others　根据语境可知，此处应表示“一些人捡广场上的垃圾，一些人清理墙上的旧海报，其他的人扫地”。another意为“另外一个”，不能表示剩下的全部，故将another改为others。‎ ‎⑦introduces改为introduce　这句话中，系动词is之后是由and连接的两个并列的表语，即to deliver environmental protection brochures和(to) introduce the importance of environmental protection，故将introduces改为introduce。‎ ‎⑧after改为before　根据语境可知，此处应表示“转眼之间，天就黑了”，before sb. know it是一种固定用法，表示“转眼之间，一下子”，故将after改为before。‎ ‎⑨beautifully改为beautiful　此处looked为系动词，后面应加形容词作表语表示状态，故将beautifully改为beautiful。‎ ‎⑩Tiring改为Tired　此处是as引导的让步状语从句。把表语形容词提到句首，后面句子用倒装，此处的形容词应该是修饰I的状态，故将Tiring改为Tired。注意句子开头首字母大写。‎ 第二节　书面表达 ‎【参考范文】‎ Dear William，‎ I am delighted to know that you are coming to China, and especially excited that you will stay in my house.
