Univeraities Branch Out
As never before in their long story, universities have become instruments of national
competition as well as instruments of peace. They are the place of the scientific discoveries that
move economies forward, and the primary means of educating the talent required to obtain and
maintain competitive advantages. But at the same time, the opening of national borders to the flow
of goods, services, information and especially people has made universities a powerful force for
global integration, mutual understanding and geopolitical stability.
In response to the same forces that have driven the world economy, universities have become
More self-consciousy global: seeking students from around the world who represent the entire
range of cultures and values, sending their own students abroad to prepare them for global careers,
offering courses of study that address the challenges of an interconnected world and collaborative
（合作的）research programs to advance science for the benefit of all humanity.
Of the forces shaping higher education none is more sweeping than the movement across borders. Over the past three decades the number of students leaving home each year to study abroad has grown at an annual rate of 3.0 percent, from 8000,000 in 1975 to 2.5 million in 2994. Most travel from one developed nation to another, but the flow from developing to developed countries id growing rapidly. The reverse flow, from developed to developing countries, is on the rise, too. Today foreign students earn 30 percent of the doctoral degrees awarded in the United States and 38 percent of those in the United Kingdom. And the number crossing borders for undergraduate study is growing as well, to 8 percent of the undergraduates at America’s best institutions and 10 percent of all undergraduates in the U.K. In the United States, 20 percent of the newly hired professors in science and engineering are foreign-born, and in China many newly hired faculty hired faculty members at the top research universities received their graduate education abroad.
Universities are also encouraging students to spend some of their undergraduate years in another country. In Europe, more than 140,000 students participate in the Erasmus program each year, taking courses for credit in one of 2, 2000 participating institutions across the continent. And in the United States, institutions are helping place students in summer internships（实习）abroad to prepare them for global careers. Yale and Harvard have led the way, offering every undergraduate at least one international study or internship opportunity and providing the financial resources to make it possible.
Globalization is also reshaping the way research is done. One new trend involves sourcing portions of a research program to another country. Yale professor and Howard Hughes Medical Shanghai’s Fudan University, in collaboration with faculty colleagues from both schools. The Shanghai center has 95 employees and graduate students working in a 4,300-square-meter laboratory seminars with scientists from both campuses. The arrangement benefits both countries;
Xu’s Yale lab is more productive, thanks to the lower costs of conducing from a word-class scientist and his U.S. team.
As a result of its strength in science, the United States has consistently led of the world in the world in the commercialization of major new technologies, from the mainframe computer and integrated circuit of the 1960s to the internet infrastructure(基础设施)and applications software of
the 1990s.The link between university-based science and industrial application is often indirect but sometimes highly visible: Silicon Valley was intentionally created by Stanford University, and
Route 128 outside Boston has long housed companies spun off from MIT and Harvard. Around the world ,governments have encouraged copying of his model, perhaps most successfully in Cambridge, England, where Microsoft and scores of other leading software and biotechnology companies have set up shop around the university.
For all its success, the United States remains deeply hesitant about sustaining the research university model. Most politician recognize the link between investment in science and national
Economic strength, but support for research funding has been unsteady. The budget of the National Institutes of Health doubled between 1998 and 2003,but has risen more slowly than inflations since then. Support for the physical sciences and engineering barely kept pace with inflation during that same period. The attempt to make up lost ground is welcome, but the nation would be better served by steady, predictable increases in science funding at the rate of long-term GDP growth, which is on the order of inflation plus 3 percent per year.
American politicians have great difficulty recognizing that admitting more foreign students can greatly promote the national interest by increasing international understanding. Adjusted for inflation, public funding for international exchanges and foreign-language study is well below the levels of 40 years ago. In the wake of September 11,changes in the visa process caused a dramatic decline in the number of foreign students seeking admission to U.S. Universities, and a corresponding surge in enrollments in Australia, Singapore and the U .K. Objections from Americans university and business leaders led to improvements in the process and a reversal of the decline ,but the United States is still seen by many as unwelcoming to international students.
Most Americans recognize that universities contribute to the nation’s well-being through their scientific research, but many fear that foreign students threaten American competitiveness by taking their knowledge and skills back home. They fail to grasp that welcoming foreign students and like immigrants throughout history-strength the nation; and second, foreign students who study in the United States become ambassadors for many of its most cherished(珍视) values when they return home. Or at least they understand them better. In America as elsewhere, few Instruments of foreign policy are as effective in promoting peace and stability as welcoming international university students.

Passage One
Questions 57 to 61 are based on following passage.
By almost any measure , there is a boom in Internet-based instruction . In just a few years , 34 percent of American universities have begun offering some form of distance learning (DL), and among the larger schools , it’s closer to 90 percent . If you doubt the popularity of the trend, you probably haven’t . It enrolls 90,000 student , a statistic used to support its claim to be the largest private university in the country.
While the kinds of instruction offered in these programs will differ, DL usually signifies a course in which the instructions post syllabi(课程大纲), reading assignments , and schedules on Websites , and students send in their assignments by e-mail . Generally speaking , face-to-face communication with an instructor is minimized or eliminated altogether.
The attraction for students might at first seem obvious . Primarily , there’s the convenience promised by courses on the Net: you can do the work, as they say , in your pajamas(睡衣). But figures indicate that the reduced effort results in a reduced commitment to the course . While dropout rates for all freshmen at American universities is around 20 percent , the rate for online students is 35 percent . Students themselves seem to understand the weaknesses inherent in the setup . In a survey conducted for eCornell , the DL division of Cornell University , less than a third of the respondents expected the quality of the online course to be as good as the classroom course.
Cleary form the schools perspective , there’s a lot of money to be saved . Although some of the more ambitious programs require new investments in servers and networks to support collaborative software , most DL courses can run on existing or minimally upgraded(升级)systems . The more students who enroll in a course but don’t come to campus , the more the school saves on keeping the lights on in the classrooms , paying doorkeepers , and maintaining parking lots , And there’s evindence that instructors must work harder to run a DL course for a variety of reasons , won’t be paid any more , and might well be paid less.

Passage Two
Questions62 to 66 are based on the following passage.
In this age of Internet chat, videogames and reality television, there is no shortage of mindless activities to keep a child occupied. Yet, despite the competition, my 8-year-old daughter Rebecca wants to spend her leisure time writing short stories. She wants to enter one of her stories into a writing contest, a competition she won last yes.
As a writer I know about winning contest, and about losing them. I know what it is like to work hard on a story only to receive a rejection slip from the publisher. I also know the pressures of trying to live up to a reputation created by previous victories. What if she doesn’t win the contest again? That’s the strange thing about being a parent. So many of our own past scars and dashed hopes can surface.
A revelation（启示）came last week when I asked her, “Don’t you want to win again?” “No,” she replied, “I just want to tell the story of an angel going to first grade.”
I had just spent weeks correcting her stories as she spontaneously（自由地）told them. Telling myself that I was merely an experienced writer guiding the young writer across the hall, I offered suggestions for characters, conflicts and endings for her tales. The story about a fearful angel starting first trade was quickly “guided” by me into the tale of a little girl with a wild imagination taking her fist music lesson. I had turned her contest into my contest without even realizing it.
Staying back and giving kids space to grow is not as easy as it looks. Because I konw very little about farm animals who use tools or angels who go to first grade, I had to accept the fact that I was co-opting（借用）my daughter’s experence.
While stepping back was difficult for me, it was certainly a good first step that I will quickly follow with more steps, putting myself far enough away to give her room but close enough to help if asked. All the while I will be reminding myself that children need room to experiment, grow and find their own voices.

Part III Listening Comprehension
11. W: I ran into Sally the other day. I could hardly recognize her. Do you remember her from high school?
M: Yeah, she was a little out of shape back then. Well, has she lost a lot of weight?
Q: What does the man remember of Sally?
12. W: We don’t seem to have a reservation for you, sir. I’m sorry.
M: But my secretary said that she had reserved a room for me here. I phoned her from the airport this morning just before I got on board the plane.
Q: Where does the conversation most probably take place?
13. W: What would you do if you were in my place?
M: If Paul were my son, I’d just not worry. Now that his teacher is giving him extra help and he is working hard himself, he’s sure to do well in the next exam.
Q: What’s the man’s suggestion to the woman?
14. M: You’ve had your hands full and have been overworked during the last two weeks. I think you really need to go out and get some fresh air and sunshine.
W: You are right. That’s just what I’m thinking about.
Q: What’s the woman most probably going to do?
15. W: Hello, John. How are you feeling now? I hear you’ve been ill.
M: They must have confused me with my twin brother Rod. He’s been sick all week, but I’ve never felt better in my life.
Q: What do we learn about the man?
16. M: Did you really give away all your furniture when you moved into the new house last month?
W: Just the useless pieces, as I’m planning to purchase a new set from Italy for the sitting room only.
Q: What does the woman mean?
17. M: I’ve brought back your Oxford Companion to English Literature. I thought you might use it for your paper. Sorry not to have returned it earlier.
W: I was wondering where that book was.
Q: What can we infer from that conversation?
18. W: To tell the truth, Tony, it never occurs to me that you are an athlete.
M: Oh, really? Most people who meet me, including some friends of mine, don’t think so either.
Q: What do we learn from the conversation?
Conversation One
M: Mary, I hope you are packed and ready to leave.
W: Yes, I’m packed, but not quite ready. I can’t find my passport.
M: Your passport? That’s the one thing you mustn’t leave behind.
W: I know. I haven’t lost it. I’ve packed it, but I can’t remember which bag it’s in.(19)
M: Well, you have to find it at the airport. Come on, the taxi is waiting. (21)
W: Did you say taxi? I thought we were going in your car.
M: Yes, well, I had planned to, but I’ll explain later. You’ve got to be there in an hour.
W: The plane doesn’t leave for two hours. Anyway, I’m ready to go now.
M: Now you are taking just one case, is that right?
W: No, there is one in the hall（客厅、门厅）as well. (22)
M: Gosh, what a lot of stuff! You’re taking enough for a month instead of a week. (20)
W: Well, you can’t depend on the weather. It might be cold.
M: It’s never cold in Rome. Certainly not in May. Come on, we really must go.
W: Right, we are ready. We’ve got the bags. I’m sure there is no need to rush. (21)
M: There is. I asked the taxi driver to wait two minutes, not twenty. (21)
W: Look, I’m supposed to be going away to relax. You’re me nervous.
M: Well, I want you to relax on holidays, but you can’t relax yet.
W: OK, I promise not to relax, at least not until we get to the airport and I find my passport.

W: Oh, I’m fed up with my job. (23)
M: Hey, there is a perfect job for you in the paper today. You might be interested.
W: Oh, what is it? What do they want? (24)
M: Wait a minute. Er, here it is. The European Space Agency is recruiting translators. (24)
W: The European Space Agency?
M: Well, that’s what it says. They need an English translator to work for French or German. (24)
W: So they need a degree in French or German, I suppose. Well, I’ve got that. What’s more, I have plenty of experience. What else are they asking for?
M: Just that. A university degree and three or four years of experience as a translator in a professional environment, They also say the person should have a lively and enquiring mind, effective communication skills and the ability to work individually or as a part of the team.
W: Well, if I stay at my present job much longer, I won’t have any mind or skills left. By the way, what about salary? I just hope it isn’t lower than what I get now.
M: It’s said to be negotiable. It depends on the applicant’s education and experience. (25) In addition to basic salary, there is a list of extra benefits. Have a look yourself.

Section B
Passage One
When couples get married, they usually plan to have children. Sometimes, however, a couple can not have a
child of their own. In this case, they may decide to adopt a child. In fact, adoption is very common today. There are about 60 thousand adoptions each year in the United States alone. Some people prefer to adopt infants, others to adopt older children. Some couples adopt children from their own countries, others adopt children from foreign countries. In any case, they all adopt children for the same reason——they care about children and want to give their adopted child a happy life. (26)
Most adopted children know that they are adopted. Psychologists and child-care experts generally think this is a good idea. However, many adopted children or adoptees have very little information about their biological parents. As a matter of fact, it is often very difficult for adoptees to find out about their birth parents because the birth records of most adoptees are usually sealed.(27) The information is secret so no one can see it.(27) Naturally, adopted children have different feelings about their birth parents. Many adoptees want to search for them, but others do not. The decision to search for birth parents is a difficult one to make. Most adoptees have mixed feelings about finding their biological parents. (28) Even though adoptees do not know about their natural parents, they do know that their adopted parents want them, love them and will care for them. (29)
Questions 26 to 29 are based on the passage you have just heard
26. According to the speaker, why do some couples adopt children?
27. Why is it difficult for adoptees to find out about their birth parents?
28. Why do many adoptees find it hard to make the decision to search for their birth parents?
29. What can we infer from the passage?
Passage Two
Catherine Gram graduated from the University of Chicago in 1938 and got a job as a news reporter in san Francisco. Catherine’s father used to be a successful investment banker. In 1933, he bought a failing newspaper, The Washington Post.(30)
Then Catherine returned to Washington and got a job, editing letters in her father’s newspaper. She married Philip Gram, who took over his father-in-law’s position shortly after and became a publisher of The Washington Post. But for many years, her husband suffered from mental illness and he killed himself in 1963. After her husband’s death, Catherine operated the newspaper. In the 1970s, the newspaper became famous around the world and Catherine was also recognized as an important leader in newspaper publishing. She was the first woman to head a major American publishing company, the Washington Post company. (31) In a few years, she successfully expanded the company to include newspaper, magazine, broadcast and cable companies.
She died of head injuries after a fall when she was 84. More than 3 thousand people attended her funeral, including many government and business leaders. Her friends said she would be remembered as a woman who had an important influence on events in the United States and the world. Catherine once wrote, “The world without newspapers would not be the same kind of world.” After her death, the employees of the Washington Post wrote, “The world without Catherine would not be the same at all.”(32)
Questions 30 to 32 are based on the passage you have just heard
30. What do we learn from the passage about Catherine’s father?
31. What does the speaker tell us about Catherine Gram?
32. What does the comment by employees of The Washington Post suggest?
Passage Three
Obtaining good health insurance is a real necessity while you are studying overseas. It protects you from minor and major medical expenses that can wipe out not only your savings but your dreams of an education abroad. (33) There are often two different types of health insurance you can consider buying, international travel insurance and student insurance in the country where you will be going.
An international travel insurance policy is usually purchased in your home country before you go abroad. It generally covers a wide variety of medical services and you are often given a list of doctors in the area where you will travel who may even speak your native language. The drawback might be that you may not get your money back immediately, (34) in other words, you may have to pay all you medical expenses and then later submit your receipts to the insurance company.
On the other hand, getting student heath insurance in the country where you will study might allow you to only pay a certain percentage of the medical cost at the time of the service and thus you don’t have to have sufficient cash to pay the entire bill at once. (35) Whatever you decide, obtaining some form of health insurance is something you should consider before you go overseas. You shouldn’t wait until you are sick with a major medical bills to pay off.
Questions 33 to 35 are based on the passage you have just heard
33. Why does the speaker advise the overseas students to buy health insurance?
34. What is the drawback of the students, buying international travel insurance?
35. What does the speaker say about students’ getting health insurance in the country where they will study?
Section C Compound Dictation
More and more of the world’s population are living in towns or cities. The speed at which cities are growing in the less developed countries is alarming (36). Between 1920 and 1960 big cities in developed countries increased (37) two and a half times in size, but in other parts of the world the growth was eight times their size.
The sheer (38) size of growth is bad enough, but there are now also very disturbing (39) signs of trouble in the comparison (40) of percentages of people living in towns and percentages of people working in industry, During the nineteenth century, cities grew as a result of the growth of industry. In Europe the proportion (41) of people living in ci8ties was always smaller than that of the workforce (42) working in factories. Now, however, the reverse (43) is almost always true in the newly industrialized world: The percentage of people living in cities is much higher than the percentage working in industry.(44)
Without a base of people working in industry, these cities cannot pay for their growth; There is not enough money to build adequate houses for the people that live there, let alone the new arrivals. (45) There has been little opportunity to build water supplies or other facilities. So the figures for the growth of towns and cities represent proportional growth of unemployment and underemployment, (46) a growth in the number of hopeless and despairing parents and starving children.
1.某大学团队研究了“干细胞间竞争”在小鼠尾部皮肤老化中的作用。结果表明，“干细胞间竞争”由胶原蛋白COL17A1驱动。他们发现，COL17A1的表达在不同干细胞间存在差异，COL17A1表达水平较高的干细胞会牢固地锚定于基底膜，且对称，并将附近COL17A1表达水平较低的细胞排挤出去。这样的细胞间竞争有助于维持皮肤的整体结构和完整性。研究同时显示，COL17A1的表达会随年龄增长而下降，也会因为应激(如氧化或紫外线辐射)而下降。最终，所有干细胞中的COL17A1表达水平都下降，皮肤随之老化。
根据这段文字，下列说确的是：
A年龄与性别因素都会影响COL17A1的表达水平
BCOL17A1表达水平较低的细胞在竞争中更具优势
C完备的防晒措施能有效提高COL17A1的表达水平
DCOL17A1的表达水平与皮肤组织的老化程度负相关
2.关于“天鹅都是白色的”这一假说，通常我们应该一只一只地调查天鹅的颜色。这种通过积累个别观察来验证假说或推导出定律的方法称为“归纳法”。但基于归纳法的推论不能带来可靠的正确性，哲学家波普提出了不依赖于归纳法的科学方法。他认为，试图证明假说是错误的才是科学的研究。例如，即使只找到了一只黑天鹅，也能证明“天鹅都是白色的”这一假说是错误的。虽然基于归纳法的验证通常是不可靠的，但如果证伪的话，则是可靠的。通过反复“设定一个用来解决问题的假说，寻找其反例来证伪假说，再设立新的假说······”，就可以进行科学的研究。
哲学家波普认为：
A科学的方法应是“可归纳”
B科学的方法应是“可证伪”
C科学的方法应是“不可证伪”
D科学的方法应是“不可归纳”
3.2020年12月，德尔黑和三位同事在《当代生物学》上发表了文章，他们认为葛洛格将温度和湿度混为一谈了。潮湿的环境使植物生长茂盛，这为动物躲避捕食者提供了荫蔽。因此，动物在潮湿的地方往往颜色更深，以伪装自己。德尔黑说，许多温暖的地方是潮湿的，但潮湿又凉爽的森林也是有的，比如塔斯马尼亚的森林，那里也有最黑的鸟类。
从这段文字可推断出：
A德尔黑的观点，动物的颜色在温度低的地方会是浅色的
B葛洛格的观点，温暖而潮湿的地区，鸟的羽毛颜色会是深色的
C葛洛格的观点，阳光充足的赤道地区，鸟的羽毛颜色会是深色的
D德尔黑的观点，阳光充足的赤道地区，鸟的羽毛颜色会是浅色的
4.大象是大型食草动物，一头成年象每天要消耗100-300公斤食物和80-200升水。亚洲象以100多种植物为食。中国野生亚洲象上世纪六、七十年代不到150头，由于政府的保护，2020年有近300头。西双版纳过去40年和最近5年气候和土地利用变化的时间数据显示，20世纪90年代后期以来，当地年平均气温稳步上升，2019-2020年比1981-2010年高1.6℃。最近两年年均降水量明显下降，高温缺水导致2020年极端干旱，西双版纳2020年3月发生严重干旱，植被生产力深度下降，这也正是亚洲象开始向北迁徙的月份。
这段文字意在说明：
A本次迁徙是亚洲象离开栖息地最远的一次
B此次亚洲象的长距离北迁超出了正常范围
C过去30年里，中国的野生大象数量翻一番
D高温干旱，植被生产力下降，导致亚洲象北迁
5.书法创作不外乎两种：一是有意识创作，二是无意识创作。有意识创作，即作者在艺术构思上以明显的主观追求为目的，或设境或立意，或以原蓝本风格为尺规，或集字等，时时想着自己在创作，以及为什么在创作，如何创作。因此，这种创作出来的作品不可能具有超脱和个性鲜明的风格与境界，即使他的技能含量再高、再精湛，也属于初级创作阶段。而无意识创作，即作者的技能含量已经高度纯熟，学识修养相当丰富，获得了创作上的大自由，将自己与创作物件融为一体，进入无意识状态、无自我之境界，任性所之，自然流露。这是书法艺术创作的高级阶段，书法艺术贵求自然，自然也即是真。
这段文字意在说明：
A书法艺术创作贵在“内心自由”
B求真才能达到创作上的大自由
C纯熟的技能是一切书法创作的基础
D无意识状态是书法创作的高级阶段
政道教育参考答案：
1.A项，“性别因素”文段未涉及，无中生有，排除;
B项，根据“COL17A1表达水平较高的干细胞会······并将附近COL17A1表达水平较低的细胞排挤出去”可知，COL17A1表达水平较高的细胞更具优势，与文意相悖，排除;
C项，根据“COL17A1的表达会······也会因为应激(如氧化或紫外线辐射)而下降”可知，文段只是介绍了紫外线辐射可以使COL17A1表达水平下降，但并未提到防晒可以提高COL17A1的表达水平，无中生有，排除;
D项，根据“所有干细胞中的COL17A1表达水平都下降，皮肤随之老化”可知，COL17A1的表达水平越低，皮肤组织的老化程度越高，即二者呈负相关，表述正确，当选。
故正确答案为D。
2.文段开篇通过“天鹅都是白色的”这一假说引出“归纳法”的定义，随后通过转折关联词“但”强调归纳法的局限，紧接着指出哲学家波普提出了另一种科学方法，即“试图证明假说是错误的”，后文对该观点进行具体的解释说明。故“哲学家波普”对于科学研究的观点是证明假说是错误的，即“可证伪”，对应B项。
A、D两项，均围绕“归纳法”展开，偏离文段重点，排除;
C项，表述与哲学家波普的观点相悖，排除。
故正确答案为B。
3.根据文段“2020年12月，德尔黑和三位同事在······以伪装自己”可知，德尔黑认为动物颜色深和湿度有关，德尔黑认为葛洛格将温度和湿度混为一谈，因此葛洛格认为动物颜色深和温度有关。由“德尔黑说，许多温暖的地方是潮湿的，但潮湿又凉爽的森林也是有的······最黑的鸟类”进一步确定，德尔黑认为动物颜色深和温度无关，与湿度相关。
A项，与文段最后一句话德尔黑的观点相悖，排除;
B项，文段中提到葛洛格将温度与湿度混为一谈，选项提到”温暖而潮湿“体现二者有区别，不符合葛洛格的观点，排除;
C项，“阳光充足的赤道地区”代表温度高，符合葛洛格的观点，当选;
D项，“阳光充足的赤道地区”没有提到湿度，和德尔黑的观点无关，排除。
故正确答案为C。
4.文段开篇介绍大象是大型食草动物，对食物和水的消耗量较大，接着介绍近些年来，中国野生亚洲象数量增长了一倍，随后介绍近年来西双版纳地区年平均气温稳步上升并引发了干旱。最后通过指代词“这”引导尾句，强调2020年3月西双版纳地区出现高温干旱，植被生产力深度下降，该时间与亚洲象北迁时间重合，即高温干旱，植被生产力下降导致数量增长的亚洲象缺乏食物，被迫北迁，故文段为分总结构，强调高温干旱，植被生产力下降，是亚洲象北迁的原因，对应D项。
A项，“亚洲象离开栖息地最远的一次”文段并未提及，无中生有，排除;
B项，“长距离北迁超出了正常范围”文段并未提及，无中生有，排除;
C项，根据“中国野生亚洲象上世纪六、七十年代不到150头······2020年有近300头”可知，“过去30年里，中国的野生大象数量翻一番”表述错误，且数量增长不是文段重点，文段重点在分析其北迁的原因，排除。
故正确答案为D。
5.文段开篇指出书法创作有两种：有意识创作和无意识创作，接着对有意识创作进行了解释，并通过“因此”指出这种在构思规则内的有意识创作属于初级创作阶段。随后文段又指出无意识创作有着创作上的大自由，并通过尾句指出这种获得自由的无意识创作是书法艺术创作的高级阶段，故文段通过对比有意识创作与无意识创作，重点强调当人处于无意识创作，也就是获得创作自由时，才能够创作出更好的书法艺术作品，对应A项。
B项，缺乏主题词“书法创作”，排除;
C项，文段强调的并非“纯熟的技能”，选项偏离文段核心话题，排除;
D项，“无意识状态”是无意识创作中的一部分内容，表述片面，排除。
故正确答案为A。

嫦娥五号回来了！带着月壤回来了！恰似一部追了23天的宇宙大片，人们期待着、盼望着，昼夜不息。
这是21世纪人类首次月球采样返回任务，标志着中国航天向前迈出一大步。作为我国复杂度最高、技术跨度最大的航天系统工程，嫦娥五号首次实现了我国地外天体采样返回，将为深化人类对月球成因和太阳系演化历史的科学认知作出贡献。
探月第三步 中国航天一大步
2020年11月24日4时30分，中国文昌航天发射场。人们欢呼、庆祝，目送长征五号全力托举嫦娥五号向着月球飞驰而去。
23天后的12月17日凌晨，内蒙古四子王旗。历经重重考验的嫦娥五号返回器携带月球样品，成功返回地面。
嫦娥五号探测器重达8.2吨，由轨道器、返回器、着陆器、上升器四部分组成，任务实施由工程总体和探测器、运载火箭、发射场、测控与回收、地面应用等五大系统共同完成，是我国探月工程“绕、落、回”三步走规划中“回”的主任务，是中国科技创新能力和决心的集中体现。
探月工程总指挥、国家航天局局长张克俭表示，嫦娥五号任务实现了我国首次月面采样与封装、月面起飞、月球轨道交会对接、携带样品再入返回等多项重大突破，其成功实施标志着我国探月工程“绕、落、回”三步走规划如期完成，中国航天向前迈出一大步。
与月亮相约 我们是认真的
就在嫦娥五号归来之际，细心的网友通过对比发现，原来10多年前，世界上的主要航天国家都纷纷出台了自己的探月规划：有的想发射探测器到月球、有的想载人登月、有的想去月球建科研站……
时至今日，能够实现自己当年定下的探月目标的，并不在多数。
经过16年努力，中国探月工程取得了“六战六捷”的优异成绩，不超预算、不降指标、不拖时间，如期完成三步走规划，圆满完成我国首次地外天体采样返回任务，在月球探测领域向全世界交出了一份亮丽的答卷。
“与月亮相约，我们无疑是认真的！”探月工程总设计师、中国工程院院士吴伟仁说，中国探月的每一个大胆设想、每一次成功实施，都是为了兑现对人民的庄严承诺，都是一棒接着一棒干、一步一个脚印走出来的逐梦之旅。
“整个嫦娥五号的研制可谓‘十年磨一剑’，一次次苦尽甘来、一次次闯关夺隘，终于将嫦娥‘五姑娘’顺利嫁了出去。”中国探月工程三期总设计师胡浩说。
“待到四子王旗会，工程大计好收官。16年来，我们完成了‘绕、落、回’三步走的目标，使我们国家在深空探测领域进入到能够从月球返回的一个先进国家的行列。”探月工程首任总指挥、中国工程院院士栾恩杰说。
牧星耕宇追梦人
从嫦娥三号、玉兔号到嫦娥四号、玉兔二号，再到嫦娥五号，一个个中国探测器成功到访月球所勾勒描绘的，是中华民族走向伟大复兴的逐梦足迹。
“那一刻，我仿佛和‘嫦娥’化身为了一体，在太空中转啊转、转啊转……”当探月工程首任首席科学家欧阳自远院士回忆起嫦娥一号被月球引力捕获时的场景，他形容自己快乐得“就像忘掉了身边的一切”。
当嫦娥五号带着月球样品返回地球，已经80多岁的欧阳自远，最牵挂的还是科研。他说：“嫦娥五号肩负着对月球科学发展的一个重大任务，我们将搞清楚更多关于月球演化历史的问题。”
半个世纪前，苏联月球16号将101克月壤样本带回地球，这是人类历史上第一个实现月球无人自动取样并送回地球的探测器。整整50年后，在地球的东方，一群追月逐梦的华夏儿女，上演了一出“月宫取宝、月轨对接、太空投递”的壮举。
所谓壮举，皆因奋斗。自嫦娥五号轨道器立项起，中国航天科技集团有限公司八院探月工程负责人张玉花就带领团队“白手起家”，展开了攻坚研制之旅。
嫦娥五号轨道器是张玉花探月之路上经历时间最长、研制最为艰苦的一个航天器。如今，历经七年研制、三年贮存，终于一朝成功梦圆。
“十年妆成始出阁，驾金车，过天河，寂寥蟾宫，新影更婀娜。玉镜为台舒秀臂，撷仙土，回故国。”网络上，一阕航天人所作的《江城子》刷屏了。
“中国人是不是离登月不远了？”刷屏后，一位网友留下这样一行问题。
正如嫦娥一号卫星系统总指挥兼总设计师、“人民科学家”叶培建院士所言：“人类在地球、太阳系都是很渺小的，不走出去，我们注定难以为继。”
展望未来，我国探月工程四期将构建月球科研站基本型，这一基本型由运行在月球轨道和月面的多个探测器组成。嫦娥七号将对月球南极地形地貌、物质成分、空间环境等进行综合探测。嫦娥八号除继续开展科学探测试验外，还将进行关键技术的验证。
“探索浩瀚宇宙是我们义不容辞的历史使命，让我们的思想跨过恒星的距离，遥望未来的美丽家园，牧星耕宇。”吴伟仁说。（据新华社北京12月17日电记者胡喆彭韵佳陈凯姿）
