2017届北京市海淀区高三上学期期末考试语文试题(word版)
2017届北京市海淀区高三上学期期末考试语文试题2017.1学校班级姓名成绩一、本大题共7小题，共22分。
阅读下面的材料，完成1—7题。
材料一：太空之家①我国成功发射入轨的天宫二号，是一个长10米、最大直径3米多、重约8吨的人造航天器。
天宫二号在离地球近400公里的近地轨道上运行，开展各种工作和实验；它既是一个真正的太空实验室，也是能供航天员居住的“太空之家”。
②高智能是天宫二号作为“太空之家”的一个突出特点。
天宫二号可以自主进行飞行轨道及姿态调整、运行状态的智能化诊断等工作。
科研人员整合了航天器十多个分系统的数据，把复杂、晦涩的专业数据浓缩成52组画面，为航天员执行任务提供了清晰、直观、舒适的显示界面。
③科幻电影中技术人员像插拔U盘一样快捷更换损坏部件的场景，将在天宫二号内真实上演。
天宫二号在供配电、热控、数据管理等系统方面采用了高集成化模块设计，打造出“插拔式”接口，航天员在几分钟内就能完成一次维修更换。
这是天宫二号作为“太空之家”的一个新亮点。
④两名航天员要在太空驻留．．30天，为避免出现“粮草不足”问题，科研人员研制了在轨补给系统。
天宫二号在太空可以边飞行边“加油”，而不必像天宫一号那样，起飞前必须把“油箱”加满，携带一吨多的推进剂。
天宫二号起飞前只加了半箱“油”，节省的重量．．产品和航天员的生活物资。
．．用来携带更多的载荷⑤科研人员还对天宫二号的居住环境进行了精心设计，使其更宜居。
航天员生活在由神舟十一号和天宫二号组成的组合体中，吃饭、睡觉在神舟飞船内，工作、娱乐和锻炼．．在天宫二号内，15立方米的空间被紧凑地隔成多个功能区。
工作区和生活区的噪音控制在50分贝以内：舱内空气温度控制在22—24摄氏度，相对湿度控制在45％—55％，这是人体感觉最舒适的温湿度。
⑥此外，科研人员在天宫一号基础上，对电子邮件传输、天地视频通话等系统进行了改进。
天宫二号增加了邮件下行能力；航天员能与地面视频互动，也能与家人私密通话。

So I went, feeling especiallyheroic. As far as I could see, I was risking my life to keep my 37 . Snow or no snow, Iwould be on time for my scheduled donation at the local 38 center.When I got there, I discovered I wasn’t 39 . Four more “hero-types” were alreadylying back in donor chairs with lines 40 to their veins, and machines quietly pumpingaway to 41 their lifesaving gifts.Seeing my fellow donors honoring their own commitments, I realized why I was there. I lay back in my donor chair, ready to make a difference in the life of someone I would never 42 .To be honest, I’d never really thought about why I donate. I just do it. But a few months ago, during one of my 43 donations I learned that my blood was specifically for a cancer patient and for a newborn baby—b oth patients needed what I would give in order to live. I’ve viewed my visits to the blood center 44 ever since.My wife Karen is a 45 , too. And more importantly, she has been on the bone marrow (骨髓) list for fifteen years, ever since she signed up to provide bone marrow to a kindergartner with leukemia(白血病). That little girl died before Karen’s bone marrow could help her, 46 Karen was called again recently. Her test results were still on file, and it turned out she was a potential 47 for someone else. The caller asked Karen if she would still be willing to become a bone marrow donor. “Yes,” she said and then immediately began answering questions on the pages of paperwork for further testing. It was a race48 time.I wish I could say that this 49 was won. It wasn’t. The caller later thanked Karen for her participation and asked a few more questions—including whethe r or not she’d 50 on the donor list. “Of course, “Karen answered.Last week Karen gave blood and next week I’ll make my usual donation. I’ll 51 an afternoon from my schedule and make an appointment. I don’t know whose life my donation may 52 . Most likely it will be a 53 , but on any day the person needing a blood product could be you or me or maybe a loved one. It is worthwhile to 54 our time to donate.I really do feel 55 every time I donate. And I like the feeling.36. A. appointment B. class C. meeting D. flight37. A. secret B. balance C. shape D. word38.

Finally, with encouragement from my family and friends, I stuck with my __46__.As I entered my classroom that first morning, I chose a seat in the back, hoping to __47__ attention. For the rest of that day, I did what I saw the other students do, and gradually, my self-consciousness （embarrassment deriving from the feeling that others are critically aware of you）faded.

I am Li Hua, president of the Student Union and I am here to tell you something important.As you may have known from the weather report, there will be a heavy rain this Friday. Thus, the school has decided to show a movie then in place of the originally planned activity of 5km jogging in the park.The movie we’ll see is American Dreams in China. This movie will definitely help you knowmore about China as it is based on a real story that happened after the policy of Reform and Opening Up was introduced. How three ambitious young men built an English-tutoring empire clearly reflects China’s recent development. The attractive plot and outstanding performance won’t let you down and the theme will certainly give you some food for thought.To better enjoy the movie, please arrive at the school auditorium at 1:50 p.m. The film starts at 2:00p.m. sharp and will last for two hours.

Seeing it shivering in the freezing wind, I felt sympathetic for it and decided to help.Concerned that it might be sick, I rushed it to the neighborhood vet. On seeing the skinny dog with dirty hair, the vet recognized it as a stray dog. He praised me for my kindness and offered to examine it for free. Fortunately, the dog was fine except for being a little underweight. Since I couldn’t affor d the time and energy, the loving vet agreed to keep it until I found it a home.That night, I posted several pictures of the puppy with a description on a local website, hoping someone would adopt it. To my great surprise, within a few hours my post received hundreds of clicks and dozens of netizens applied to be the owner.After several telephone “interviews”, a couple became my final choice since they have rich experience in dog raising. We met the next day at the vet’s. For the couple, it was love at first sight. The puppy, as if aware of what was going on, kept on wagging its tail. As I waved the contented family goodbye, I felt a load off my mind and pride in my heart. If everyone can treat animals with love, the world will surely be a nicer place.第四部分：书面表达（共两节，35分）第一节（15分）一、评分原则：1．本题总分15分，按4个档次给分。
北京市海淀区2017届高三年级第一学期期末练习
北京市海淀区2017届高三年级第一学期期末练习语文一、本大题共7小题，共22分。
阅读下面的材料，完成1—7题。
材料一：太空之家①我国成功发射入轨的天宫二号，是一个长10米、最大直径3米多、重约8吨的人造航天器。
天宫二号在离地球近400公里的近地轨道上运行，开展各种工作和实验；它既是一个真正的太空实验室，也是能供航天员居住的“太空之家”。
②高智能是天宫二号作为“太空之家”的一个突出特点。
天宫二号可以自主进行飞行轨道及姿态调整、运行状态的智能化诊断等工作。
科研人员整合了航天器十多个分系统的数据，把复杂、晦涩的专业数据浓缩成52组画面，为航天员执行任务提供了清晰、直观、舒适的显示界面。
③科幻电影中技术人员像插拔U盘一样快捷更换损坏部件的场景，将在天宫二号内真实上演。
天宫二号在供配电、热控、数据管理等系统方面采用了高集成化模块设计，打造出“插拔式”接口，航天员在几分钟内就能完成一次维修更换。
这是天宫二号作为“太空之家”的一个新亮点。
④两名航天员要在太空驻留30天，为避免出现“粮草不足”问题，科研人员研制了在轨补给系统。
天宫二号在太空可以边飞行边“加油”，而不必像天宫一号那样，起飞前必须把“油箱”加满，携带一吨多的推进剂。
天宫二号起飞前只加了半箱“油”，节省的重量用来携带更多的载荷产品和航天员的生活物资。
⑤科研人员还对天宫二号的居住环境进行了精心设计，使其更宜居。
航天员生活在由神舟十一号和天宫二号组成的组合体中，吃饭、睡觉在神舟飞船内，工作、娱乐和锻炼在天宫二号内，15立方米的空间被紧凑地隔成多个功能区。
工作区和生活区的噪音控制在50分贝以内：舱内空气温度控制在22—24摄氏度，相对湿度控制在45％—55％，这是人体感觉最舒适的温湿度。
⑥此外，科研人员在天宫一号基础上，对电子邮件传输、天地视频通话等系统进行了改进。
天宫二号增加了邮件下行能力；航天员能与地面视频互动，也能与家人私密通话。
（取材于《人民日报》2016年9月16日）1．根据“材料一”，下列不是．．天宫二号作为“太空之家”的特点的一项是（）（2分）A．高智能B．更换损坏部件方便快捷C．更宜居D．增设天地视频通话系统2．下列对“材料一”中加点字词的解说，不正确．．．的一项是（）（2分）A．“驻留”中的“驻”是“停留”的意思。

+项的取值相同，不妨设121M i i i a a a +==⋅⋅⋅=此时有：111M i a M M ++=+>，矛盾.故对于任意的正整数M ，必存在*k ∈N ，使得k a M >. ………….. 8分（Ⅲ）充分性：当11a =时，数列{}n a 为1，1，2，1， 3，1，4，…，1，1k -，1，k ，… 特别地，21k a k -=，21k a =故对任意的*n ∈N（1）若n 为偶数，则21n n a a +==（2）若n 为奇数，则23122n n n n a a +++=>= 综上，2n n a a +≥恒成立，特别地，取1m =有当n m ≥时，恒有2n n a a +≥成立 ………….11分必要性：方法一:假设存在1a k =（1k >），使得“存在m N *∈，当n m ≥时，恒有2n n a a +≥成立”则数列{}n a 的前21k +项为k ，1， 1，2，1， 3，1，4，…，1，1k -， 1，k2，2，3，2，4， …，2，1k -，2，k3，3，4，…，3，1k -，3，k⋅⋅⋅2k -，2k -，1k -，2k -，k1k -，1k -，kk后面的项顺次为1k +，1，1k +，2，…，1k +，k2k +，1，2k +，2，…，2k +，k3k +，1，3k +，2，…，3k +，k…… 对任意的m ，总存在n m ≥，使得n a k =，21n a +=，这与2n n a a +≤矛盾，故若存在m N *∈，当n m ≥时，恒有2n n a a +≥成立，必有11a =………….. 13分 方法二： 若存在m N *∈，当n m ≥时，2n n a a +≥恒成立，记{}12max ,,,m a a a s =. 由第（2）问的结论可知：存在k N *∈，使得k a s >（由s 的定义知1k m ≥+） 不妨设k a 是数列{}n a 中第一个．．．大于等于1s +的项，即121,,,k a a a -均小于等于s .则11k a +=.因为1k m -≥，所以11k k a a +-≥，即11k a -≥且1k a -为正整数，所以11k a -=. 记1k a t s =≥+，由数列{}n a 的定义可知，在121,,,k a a a -中恰有t 项等于1. 假设11a ≠，则可设121t i i i a a a ====，其中1211t i i i k <<<<=-， 考虑这t 个1的前一项，即12111,,,t i i i a a a ---， 因为它们均为不超过s 的正整数，且1t s ≥+，所以12111,,,t i i i a a a ---中一定存在两项相等，将其记为a ，则数列{}n a 中相邻两项恰好为（a ，1）的情况至少出现2次，但根据数列{}n a 的定义可知：第二个a 的后一项应该至少为2，不能为1，所以矛盾！ 故假设11a ≠不成立，所以11a =，即必要性得证！ ………….. 13分 综上，“11a =”是“存在m N *∈，当n m ≥时，恒有2n n a a +≥成立”的充要条件.。

In her other hand, she holds a paper carrier bag.I know this lady. It is not her first visit. She is the boy’s grandmother, and her daughter bought the house next door last October.Her daughter, Nicole, speaks fluent English. But she is now in Shanghai, and her parents are here with the little boy. Nicole has obviously told her mother that I am having heart surgery soon, so her mother has decided I need more nutrients. (56题)I know what is inside the bag—a thermos with hot soup and a stainless-steel container with rice, vegetables and either chicken, meat or shrimp, sometimes with a kind of pancake. This has become an almost-daily practice.(57题) Communication between us is somewhat affected by the fact that she doesn’t speak English and all I can say in Chinese is hello. Once, she brought an iPad as well as the food. She pointed to the screen, which displayed a message from her daughter telling me that her mother wanted to know if the food was all right and whether it was too salty. I am not used to iPads, so she indicated I should go with her to her house. Then, she handed the iPad to her husband and almost immediately I found myself looking at Nicole in Shanghai and discussing her mother’s cooking and salt intake. Instantly, tears welled in my eyes.“Your mother just can’t be bringing me meals like this all the time,” I insisted. “I can hardly do dishes in return.”“Oh, no, Lucy.” Nicole said. “Mum doesn’t like western food. Don’t worry about it; she has to cook for the three of them anyway, and she wants to do it.”The doorbell keeps ringing and there is the familiar brown paper carrier bag, handed smilingly to me.I am now working on some more Chinese words—it’s the least I can do after such a display of kindness.“Thank you” is, of course, the first one. Somehow, it seems inadequate. (58题)56. The elderly Chinese lady visits Lucy regularly because______.A. Lucy pays her to deliver foodB. Lucy likes cooking Chinese foodC. she cares about Lucy’s state of healthD. she wants to make friends with Lucy57. Nicole’s mum took an iPad to Lucy’s home for_________.A. displayingB. communicatingC. cookingD. chatting58. In this passage Lucy mainly expresses her ______.A. preference for the Chinese foodB. gratitude to the Chinese familyC. love of the advanced technologyD. affection for the Chinese languageBChinese Emoji (表情符号) Circles Globe (62题)“Funny”, a made-in-China emoji, seems to have recently moved beyond China. Now, it is more than an emoji, but a cultural expansion.●Reaching Global MarketsA series of “funny” emoji-based bolsters (抱枕) have attracted the attention of Japanese customers. Even if one bolster is more than three times as expensive as in China, it doesn’t kill their desires to buy it. One Japanese customer Miki said, “They are just so cute and I bought three bolsters at one time for my family. And every time I see them, my mood just brightens suddenly.” (59题)A Japanese netizen Kiro Kara said, “I think the emoji implies very complicated meanings. My dad will send it when he doesn’t agree with someone but he has to say something and behave politely.”●Addition to Domestic Social MediaCompared with Japanese impressions of the “funny” emoji, Chinese netizens prefer to use the emoji to tease one another on social media.One commonly seen online comment is, “We strongly suggest stopping the usage of the emoji. Because every time other people send me the emoji, I feel very uncomfortable and consider myself as a fool.”Regarded as the most popular emoji, the “funny” emoji has received much attention since its release in 2013. In fact, the “funny” emoji is the updated version of its original one; “funny” has a smiley mouth, two eyebrows and a naughty look. All these characteristics present users a sense of satire (讽刺). (60题)●In Everyday Use AbroadIt’s not the first time the Chinese emoji takes the world stage. Earlier this year, one emoji from the Chinese basketball celebrity Yao Ming has been spread through the Middle East region. In a city in southern Egypt, Yao’s smiling emoji has appeared frequently in local traffic signs to remind people the road ahead is one-way. Many locals do not know Yao Ming but are familiar with his emoji and nickname “Chinese Funny Face”.As a new online language, emojis have become a necessary part of people’s daily life, helping people express their views in a more vivid and precise way. (61题) Also, it can help foreigners learn about Chinese culture. But how to properly use “the fifth innovation in China” without hurtingothers and turn them into commercial advantages still needanswers.59. Why do the bolsters attract Miki’s attention?A. They are inexpensive.B. They helpreach an agreement.C. They help brighten the mood.D. They are helpful to express desire.60. According to the passage, which of the following is the latest “funny” emoji?A. B. C. D.61. Emojis are so popular worldwide mainly because people use them to ______.A. express their views more vividlyB. present their sense of satire directlyC. imply very complicated meanings properlyD. tease one another on social media purposely62. The main purpose of the text is to ______.A. promote the emoji worldwideB. teach us how to use the emojiC. explain the meaning the emojiD. show us the popularity of the emojiCEvery year billions of pounds are spent on hair loss treatment. If we succeed in curing hair loss with 3D printed hair follicles(⽑囊), it will be a huge revolution.L’Oreal, the cosmetics firm is partnering with a French bio-printing company called Poietis, which has developed a form oflaser(激光) printing for cell-based objects. Poietis’ technique begins with the creation of a digital map that determines where living cells and other tissue components should be placed to create the desired biological structure. This involves how the cells are expected to grow over time. The on the digital map is then turned into instructions for the printing equipment, so that it can lay down tiny droplets made out of the cell-based "bio ink" one layer at a time. The printing process involves bouncing a pulsing laser off a mirror and through a lens, so that when it hits a ribbon(⾊带) containing the bio ink, a droplet of the matter falls into place. About 10,000 of these micro-droplets are created every second. (63题)It typically takes about 10 minutes to print a piece of skin 1cm wide by 0.5mm thick. However, since hair follicles are complex and consist of 15 different cells in a structure, they may take longer.Poietis is not the only company working on bio-printing, but most others use another way, which involves pushing a bio-ink through a nozzle(喷嘴), rather than lasers to build their tissue.Poietis suggests its technique puts less stress on the biological matter, meaning there is less risk of causing it damage. (64题)Alopecia UK—a charity that provides support and advice about hair loss—has mixed feelings about the development. “It is encouraging to know that (66题)companies such as L’Oreal are investing in technology that may help those with hair loss in the future,” said spokeswoman Amy Johnson.(66题) “However, we would suggest it’s still very early to be getting excited about what this potentially could mean for those with medical hair loss. At this point it is unclear as to whether this technology could benefit those with all types of hair loss.”(65题)“Also, if this new technology does lead to a treatment option, given the high costs of existing hair transplant procedures, how many people will be able to realistically afford any new technological advances that may become available? (65题) As with any other research and development into processes that may be able to help those with hair loss, we watch with great interest.”63. What does Paragraph 2 mainly tell us?A. How the printing process is carried out.B. Where the living cells should be placed.C. How long the cells are expected to grow.D. What the printing equipment is made up of.64. What does the underlined word “it” in Paragraph 4 refer to?A. hair follicleB. biological matterC. nozzleD. bio-ink65. The passage implies that the new technology may ______.A. meet some practical challengesB. help people with hair loss at presentC. offer solutions to all problems of hair lossD. cost a large sum of money to transplant hair66. What is Amy Johnson’s attitude towards the new technology?A. Disapproving.B. Optimistic.C. Cautious.D. Negative.DThere is no doubt eCommerce is growing, and it will continue to grow. However, physical stores would not die as a result of the rise of eCommerce, at least not in the near future. The idea that eCommerce is taking over physical stores has already misguided many people. Physical stores are far from vanishing, and there are some solid reasons for it. (69题)The projections for online spending is optimistic with $150 billion expected to be spent in the coming three years, yet we are also expecting (67题) $300 billion in spending at physical stores in the same duration. Do you still think that physical-store shopping is too small to sustain the eCommerce blow?Even though consumers are staying away from physical stores that follow older concepts, yet we are seeing the rise of fresh concept stores all around the US. We are seeing innovative and attractive success stories of physical stores, ranging from clothes stores to restaurants to health spas. It would be easy to assume that this trend will continue.Indeed, many shopping malls are dying, yet there are still those shopping centers that areperforming well. You can see this for yourself by visiting shopping malls near you. What I want to emphasize here is that not all shopping centers are made equal, just like not all eCommerce retailers are made equal. Both shopping malls and eCommerce sites can lose business if they fail to maintain productivity through improvements and innovations. (68题) When you visit shopping centers that are serious about their business, you would see their shops and parking lots packed.On the other hand, even e -tailers like Amazon have experimented with pop -up shopping concepts. It is important to bear in mind that consumers prefer face -to -face interactions instead of online interactions during shopping, meaning that physical stores are going to stay there.Still, eCommerce retailers are seeing all of their excitement disappear as they settle the sales tax problem associated with e -tailing. As of now, five states of America have already imposed sales tax on purchases through eCommerce sites, and e -tailers in those states have already witnessed 6 to 12 percent decrease in sales.This reinforces the fact that physical stores are here to stay, and if you are still undervaluing their growth, you are omitting a huge chunk of the retail representation.

北京市海淀区2017届高三年级第一学期期末练习语文一、本大题共7小题，共22分。
阅读下面的材料，完成1—7题。
材料一：太空之家①我国成功发射入轨的天宫二号，是一个长10米、最大直径3米多、重约8吨的人造航天器。
天宫二号在离地球近400公里的近地轨道上运行，开展各种工作和实验；它既是一个真正的太空实验室，也是能供航天员居住的“太空之家”。
②高智能是天宫二号作为“太空之家”的一个突出特点。
天宫二号可以自主进行飞行轨道及姿态调整、运行状态的智能化诊断等工作。
科研人员整合了航天器十多个分系统的数据，把复杂、晦涩的专业数据浓缩成52组画面，为航天员执行任务提供了清晰、直观、舒适的显示界面。
③科幻电影中技术人员像插拔U盘一样快捷更换损坏部件的场景，将在天宫二号内真实上演。
天宫二号在供配电、热控、数据管理等系统方面采用了高集成化模块设计，打造出“插拔式”接口，航天员在几分钟内就能完成一次维修更换。
这是天宫二号作为“太空之家”的一个新亮点。
④两名航天员要在太空驻留30天，为避免出现“粮草不足”问题，科研人员研制了在轨补给系统。
天宫二号在太空可以边飞行边“加油”，而不必像天宫一号那样，起飞前必须把“油箱”加满，携带一吨多的推进剂。
天宫二号起飞前只加了半箱“油”，节省的重量用来携带更多的载荷产品和航天员的生活物资。
⑤科研人员还对天宫二号的居住环境进行了精心设计，使其更宜居。
航天员生活在由神舟十一号和天宫二号组成的组合体中，吃饭、睡觉在神舟飞船内，工作、娱乐和锻炼在天宫二号内，15立方米的空间被紧凑地隔成多个功能区。
工作区和生活区的噪音控制在50分贝以内：舱内空气温度控制在22—24摄氏度，相对湿度控制在45％—55％，这是人体感觉最舒适的温湿度。
⑥此外，科研人员在天宫一号基础上，对电子邮件传输、天地视频通话等系统进行了改进。
天宫二号增加了邮件下行能力；航天员能与地面视频互动，也能与家人私密通话。
（取材于《人民日报》2016年9月16日）1．根据“材料一”，下列不是．．天宫二号作为“太空之家”的特点的一项是（）（2分）A．高智能B．更换损坏部件方便快捷C．更宜居D．增设天地视频通话系统2．下列对“材料一”中加点字词的解说，不正确．．．的一项是（）（2分）A．“驻留”中的“驻”是“停留”的意思。
B．“重量”中的“重”字，第七画是“l（竖）”。
C．“载荷”与“下载”中的“载”，读音不同。
D．“锻炼”不可以写作“锻练”。
材料二：天官二号守护者——伴随卫星①天宫二号的伴随卫星（以下简称“伴星”）重约47千克，体积相当于一台普通打印机。
在发射时，伴星由一个微型的释放机构牢牢连接在天宫二号上，进入轨道后才会被释放到太空中，围绕着天宫二号或远或近不同角度地伴随飞行。
它带有一台2500万像素的高分辨率全画幅可见光相机，当神舟十一号载人飞船与天宫二号交会对接时，伴星将在旁边拍下这极其重要的一刻。
科研人员将它戏称为“天宫和神舟大婚的摄影师”。
②除了为“大婚”摄影，伴星另一个重要任务是对天宫二号表面状态进行检查。
随着人类发射航天器数量的增多，太空中的碎片也在增多，而空间站等身躯庞大的航天器在轨时间也越来越长，万一和微小的空间碎片有个磨擦，就可能形成漏热的裂缝，带来巨大的危险。
伴星的红外相机，就好比一个非接触式的医疗热像仪，天宫二号哪里“体温”出现异常，它都可以及时发现并报警。
③与神舟七号伴飞小卫星相比，天宫二号伴星看上去“瘦”了一圈，体积减小了1/4。
天宫二号伴星采用了高集成化设计，如在伴星所携带的单机中，有一个微型测控应答机，在传统卫星上常重达5千克，现在被压缩成长110毫米、重量不足100克的小家伙。
此次伴星的功能密度要求更高，科研人员严格采用了很多宇航级的高可靠元器件，并进行了大量安全可靠的试验。
④为减轻整星重量，研发团队要求所有电子学供货单位把传统的单机外壳全部去掉，只留下电路板，并根据微纳卫星的尺寸特点和接口形式，严格制定统一标准，重新设计标准电路板模块。
伴星的结构设计师是两位女性，她们用特有的细腻，为伴星设计了镂空刻槽的减重结构板，星体最薄处仅有0.5毫米，其精美程度让装配师惊讶不已。
⑤这样，省出的空间可以使天宫二号伴星搭载更多载荷，提高主星应用效率，扩大新技术的空间验证平台。
（取材于《文汇报》2016年9月18日）3．根据“材料二”，下列不能．．说明天宫二号伴星“采用了高集成化设计”的一项是（）（2分）A．降低了微型测控应答机重量B．进行了大量安全可靠的试验C．重新设计了标准电路板模块D．使用镂空刻槽的减重结构板4．根据“材料二”，用简明的语言解释什么是“伴随卫星”。
（5分）材料三：中国载人航天工程“三步走”发展战略①20世纪90年代初，中国正式启动载人航天工程，并确立“三步走”发展战略。
②第一步为载人飞船阶段。
主要任务是研制裁人飞船，将航天员送到太空，开展空间应用实验并返回。
2003年，神舟五号飞船完成首次载人飞行任务；2005年，神舟六号飞船完成多人多天飞行试验任务。
至此，中国载人航天工程实现了第一步战略目标。
③第二步是空间实验室阶段。
2008年，神舟七号飞行任务圆满完成，航天员出舱活动，标志着中国掌握了太空行走的关键技术。
2011年，天宫一号出场，这个目标飞行器先后与神舟八号、神舟九号和神舟十号开展了交会对接试验并取得成功，自动及手动控制交会对接技术得到验证。
同时，天宫一号经过对接后，被改造成为太空中一个短期有人照料的空间实验平台，多名航天员短期驻留太空，参与完成多项科学实验，载人航天工程取得关键性进展，第二步第一阶段任务圆满收官。
④建造空间站要突破四项关键技术。
前两项分别为太空行走技术和空间交会对接技术，已分别于2010年前后实现；其余两项是在轨补给技术和再生式生命保障技术，需要天宫二号空间实验室来实现，这也是第二步第二阶段的任务。
天宫二号搭载的再生生命保障系统，能够把人体排出的体液进行物理、化学的处理，让它循环再生，从而持续稳定地维持航天员的生命健康。
这一技术得到验证之后，还将突破航天员在空间站长期驻留的技术。
天宫二号将首次实现与货运飞船天舟一号的对接，以验证货物运输和推进剂在轨补加等空间站建造与运营的关键技术。
在以后的空间站建造和运营中，货运飞船将担负重要的任务。
⑤空间站是中国载人航天工程战略的第三步，计划2020年左右建成。
届时，中国将成为继俄罗斯、美国之后，第三个拥有空间站技术的国家。
中国空间站2022年全面运行，其质量超过90吨，至少包括一个核心舱、两个科学实验舱；能与各种实验舱、载人飞船和货运飞船进行对接。
核心舱要求长期有人驻守。
⑥由16国建成的国际空间站使用期限到2025年，而中国空间站将在轨运行至少10年。
那时，中国空间站将是人类唯一的太空家园。

故近者歌讴而乐之，远者竭蹶而趋之，四海之内若一家，通达之属莫不从服，夫是之谓人师。
《诗》曰：“自西自东，自南自北，无思不服。
”此之谓也。
夫其为人下也如彼，其为人上也如此，何谓其无益于人之国也？”昭王曰：“善！”若夫论德而定次，量能而授官，使贤不肖皆得其位，能不能皆得其官；万物得宜，事变得应，言必当理，事必当务，君子之所长也。
