It was May 1945 when what would become one of America's most popular home cooking techniques first entered the English dictionary．In her cookbook，How to Cook and Eat in Chinese，55 year old Chinese immigrant (移民) Chao Yang Buwei described a process common in her homeland，where cooks would cut meat and vegetables into small bites and tumble (翻滚) them rapidly together over heat．“The Chinese term for the technique，ch'ao，cannot be accurately translated into English，” Chao complained．For short，she decided，“We shall call it ‘stir fry’．” The term soon made its way into the American language and has since taken on a life of its own．
Chao came to cooking unexpectedly．A doctor by profession，she gave up her medical career to move to the United States in 1921 after her husband，the famed linguist (语言学家) Chao Yuanren，was offered a job at Harvard．Bored at home and only able to speak a little English，she turned to cooking dishes that reminded her of China：soups with mushrooms and pork flavored with soy sauce．
She eventually agreed when a friend begged her to write a cookbook．Chao's eldest daughter helped her translate recipes from Chinese to English，before her husband put the finishing touches on the language，often adding phrasing that even Chao recognized as awkward．This stylistic conflict resulted in a cookbook that Chao was “ashamed to have written”， as she declared in an author's note．
The cookbook succeeded，going into multiple printings by the end of 1945，though critics largely overlooked the anger in Chao's words．English language Chinese cookbooks had been published as far back as 1911 in the United States，but Chao's was the first that refused to westernize Chinese cooking．She may have given America a well worn phrase，but she knew that some aspects of the immigrant experience resist translation．Chao's contribution to American food culture should have been enough to make her into headlines，but the New York Times did not even honor her with an obituary (讣告) upon her death．How many other cooking pioneers like Chao，immigrants who didn't silence their difference in order to gain broad approval，still await rediscovery
4．Which of the following is true about “ch'ao”？
A．It is a cooking technique used only in America．
B．It quickly found a place in the American language．
C．It was accurately translated into “stir fry” by Chao．
D．It means mixing together small pieces of materials．
5．What made Chao turn to traditional Chinese cooking
A．Her interest in cooking．
B．Her profession as a doctor．
C．Inadaptability to life in America．
D．Encouragement from her husband．
6．What is most special about Chao's cookbook
A．Consistency in writing style．
B．The refusal to westernize Chinese cooking．
C．Success in pleasing the American taste．
D．The reflection of western culture．
7．What can be inferred from the last paragraph
A．Chao's cookbook was largely overlooked by critics．
B．Chao followed the same trend as other cookbook writers．
C．Chao isn't the only immigrant that deserves giving credit to．
D．Chao gained popularity for her unwillingness to silence her differences．
C
Transportation and communication networks bring people together．Yet sometimes people themselves bring forth barriers to transportation and communication．In some countries，laws stop people from moving freely from place to place．
Over the centuries，many groups of people have been denied the freedom to travel because of their race，religion，or nationality．In the Middle Ages，for example，Jews were often forbidden to move about freely within certain cities．South Africa's government used to require black Africans to carry passes when they travelled within the country．Some governments required all civilians to carry identification papers and to report to government officials whenever they moved．
Countries set up customs posts at their borders．Foreign travellers must go through a customs inspection before they are allowed to travel in the country．Usually travellers have to carry special papers such as passports and visas(签证)．Some countries even limit the number of people who can visit their country each year．Others allow tourists to visit only certain areas of the country，or they may require that travellers be with an official guide at all times during their stay．Many of those barriers to travelling also act as barriers to communication．When two governments have divisions in important matters，they usually do not want their civilians to exchange news or ideas freely．Countries often try to keep military or industrial secret information．
Today，people have the ability to travel，to communicate，and to transport goods more quickly and easily than ever before．Natural barriers that were difficult or dangerous to cross a hundred years ago can now be crossed easily．The barriers that people themselves make are not so easy to overcome．But in spite of all the different kinds of barriers，people continue to enjoy travelling and the exchange of goods and ideas．
8．What are the examples in paragraph 2 used to tell the readers
A．People have been allowed to travel freely within the country．
B．People have not been permitted to travel freely for various reasons．
C．Travellers have to carry special papers such as passports and visas．
D．Customs posts are necessary at the borders of the countries．
9．Why do some governments limit the freedom of communication
A．Because they intend to keep their national secrets unknown to others．
B．Because they think such freedom will lead to wars．
C．Because they often disagree with each other on important matters．
D．Because they want to show their authority over communication．
10．What can be learned from the passage
A．People do not care about the removal of barriers between countries．
B．People can not remove the obstacles made by themselves．
C．Man made barriers are sometimes harder to overcome than natural ones．
D．Barriers should be taken for granted as they always exist．
11．Which of the following can serve as the best title of the passage
A．Barriers Made by People
B．Functions of Communication
C．Restrictions on Transportation
D．Progress of Human Society
D
Want to pick up that new best seller for your flight，but not sure you want to spend the money
This will change your mind．
If you've done a lot of travelling，you've probably noticed that the bookstores at airports all look pretty similar．They've all got familiar logos，the walls of inviting plane snacks，and，of course，the towers of new hardcover books．Chances are you've wanted to grab one of those books for the plane ride．However，those hardcover books are a little pricey．Is it worth it to splurge，just to relieve the midair boredom
Yes it is—because of a cool program that these bookstores have in place．These similar airport stores are all owned by the company Paradies Lagardère，and all of those stores take part in what's called the “Read and Return”program．It's exactly what it sounds like．Whenever you buy one of those books，you've got six months to finish it and bring it back to the same，or another，Paradies Lagardère location．When you do that，you get half your money for the original purchase back．
If you're going on a trip，buy that book you've been dying to read．When you go back to the airport for the return trip，bring the book back with you and get half the money back．While you're still in the bookstore，go ahead and get that other book you've been dying to read．Or the sequel to the book you read on the way there．Either way，your boredom on the flight back will be cured．And it gets better：the book you gave back will be re sold for half price! Here's what you can get for free at an airport．
There are two things you do need to make sure of．You have to bring back the receipt to get your money back．Also，the book needs to be in decent condition．But other than that，this program couldn't be easier．In a way，it's like a buy one get one half off deal for books．Or get two books for the price of one and a half．Either way，count us in．
12．What does the underlined word “splurge” in paragraph 3 mean
A．Spend the money．
B．Take the effort．
C．Take the trouble．
D．Spend the time．
13．How does the “Read and Return” program run
A．You can read books for free in any Paradies Lagardère store．
B．You can buy books for half price in airport bookstores．
C．You need to return the book to the same store where you buy it．
D．You can get half your money back if you return the book timely．
14．What can we learn from the last paragraph
A．It is difficult to take part in the program．
B．The receipt is necessary if you want to return the book．
C．The program is popular with readers．
D．The program runs successfully．
15．Why does the author write this passage
A．To encourage people to read on airplanes．
B．To introduce Paradies Lagardère company．
C．To advertise the “Read and Return” program．
D．To show the advantages of reading on airplanes．

Have you ever been labeled a “perfectionist”？Or do you consider yourself to be one？It's attractive to see perfectionism as a positive quality—it shows that we pay close attention to detail and get things right! And，it is often viewed as a strength that helps people to produce high quality work． 16 It can damage self esteem，cause relationship problems，and，in extreme cases，it may even lead to serious health problems．If you think that you have a problem with perfectionism，the following strategies can help you to lessen its negative effects．
Set realistic goals． 17 Instead，learn to think about your most important life and career goals．Then，break them down into smaller steps．Not only will this make it easier to reach your objectives，but you'll also experience the thrill of achieving them．
18 If you're feeling anxious or unhappy about a task，they may be telling you that you're trying to achieve the impossible．And adjust your targets accordingly! Perfectionists are often likely to start negative self talk．If you catch yourself doing this，stop! Try using thought awareness to question your negative thoughts and add some positivity!
Focus on the bigger picture．Perfectionism can cause “tunnel vision”—when you focus on one small part of something but ignore the rest．You might，for instance，focus on getting a minor part of a presentation right，like the special effects，instead of concentrating on the meaning that you are trying to deliver．Remember to keep your focus on the bigger picture． 19
Relax and go with the flow．The pursuit of perfection can make it extremely difficult to relax．And perfectionists prefer to maintain focus and to stick to their carefully laid plans．But relaxation isn't just necessary for a healthy life．It can also improve your productivity and well being．And you'll be better at keeping perfectionism under control if you're feeling rested，clear headed and happy． 20 Get outside，be open to new experiences and new people，make use of relaxation techniques，and recognize when you need to switch off．
Most of all，don't allow perfectionism or fear of failure to stop you from experiencing new things．Be open to new ways of thinking，new people，and new experiences．You might just find that letting go actually boosts your well being，your relationships，and your performance．
A．Listen to your emotions．
B．So，take regular breaks at work．
C．Seek advice from qualified health professionals．
D．Your failings will seem less significant and you'll reduce the urge to be perfect．
E．However，when perfectionism gets out of control，it can do more harm than good．
F．Perfectionists often set objectives so high that there's little hope of ever achieving them．
G．If you're afraid to make mistakes，it's difficult to generate new ideas and seize opportunities．

阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
When a tornado hit a small town nearby, many families were left homeless． Afterwards, all the local newspapers carried stories of the families who suffered the hardest to appeal to people's attention and assistance．
One Sunday, a particular picture especially touched me． A young woman stood in front of a mobile home, a depressed expression on her face． A young boy, seven or eight years old, stood at her side, eyes downcast． Hiding behind her skirt was a tiny girl who stared into the camera, wide eyes with confusion and fear． The article below gave clothing sizes closely matched ours． This would be a good opportunity to teach my seven year old twins, Brad and Brett, and three year old Meghan to help those less fortunate than themselves．
“We have so much． And these poor people now have nothing，” I said． “We'll share what we have with them．” I brought three large boxes down from the room upstairs and placed them in the living room． Meghan watched seriously, as the boys and I filled one of the boxes with canned goods and foods． While I sorted through our clothes, I encouraged the boys to go through their toys and donate some of their less favorite things． The boys were pleased to join． Brad rose and went to his room fast． He came back bringing his action figures that he played with not so frequently． Brett also jumped up and ran to fetch some of his Matchbox cars and airplane models． Meghan watched quietly as the boys piled up abandoned toys．
The boys placed the objects they had chosen to donate into one of the boxes while I filled the third box with clothes． Meghan walked up with Lucy, her worn, faded, best loved rag doll hugged tightly to her chest． “I'll help you find something for the little girl, too，” I said to the little Meghan．
注意：1．续写词数应为150左右；
2．请按如下格式作答。
“Mommy，I will give Lucy to them，”Meghan turned to me．___________

“Mommy, I will give Lucy to them，” Meghan turned to me． “Oh, honey，” I said． “You don't have to give Lucy． You love her so much．” Meghan nodded seriously, eyes glistening with tears． “Lucy makes me happy, Mommy． Maybe she'll make that little girl happy, too．” She paused in front of the box that held the toys, pressed her round little face into Lucy's flat face, gave her a final kiss, and then laid her gently on top of the other toys． The boys watched, openmouthed, as their baby sister placed her favorite doll in the box．
Recognizing what little Meghan's gesture meant, I removed my old jacket from the box of clothes． I replaced it with the new hunter green jacket that I had bought on sale last week． I believed the young woman in the picture would like it and fit it as much as I did． The boys had also been inspired by our behavior and carried their beloved things． We all wished the family could pass the difficult period as soon as possible and that they would love the things we gave them with all our heart．

17．F　[根据段落主旨句“Set realistic goals．”可知，本段讲述的是要想减少完美主义的负面影响，可以通过设定现实的目标。根据下文“Instead，learn to think about your most important life and career goals．”可知，下文说的是如何设定现实的目标。F项意为“完美主义者往往把目标定得太高，以至于实现目标的希望渺茫。”选项内容符合段落主旨，说出了完美主义者在设定目标时出现的问题，下文针对这个问题给出了解决方法。]
18．A　[根据下文“If you're feeling anxious or unhappy about a task，they may be telling you that you're trying to achieve the impossible．And adjust your targets accordingly！”可知，本段介绍了我们情绪的变化会告诉我们所制定的目标是否合理。A项意为“倾听你的情绪。”选项内容能够概括段落主旨，告诉我们倾听情绪的重要性，下文中的“anxious or unhappy”是对选项中的“emotions”的举例。]

20．B　[根据上文“But relaxation isn't just necessary for a healthy life．It can also improve your productivity and wellbeing．And you'll be better at keeping perfectionism under control if you're feeling rested，clearheaded and happy．”可知，本段告诉我们放松有助于提高工作效率，可以让你更好地控制完美主义。B项意为“所以，在工作中定时休息。”选项内容与上文为因果关系，正因为放松有助于提高工作效率，所以应该在工作中定时休息。]
【语篇解读】　本文是一篇记叙文。作者讲述了自己作为联合国维和人员在中非共和国工作的经历。
21．B　[在此之前，“我”是一名飞行员，“我”喜欢“我”的工作。根据下文的转折“However，I felt it was my duty to help innocent people”可知，前后是转折关系，作者之前是一名飞行员，喜欢这份工作，但是作者觉得自己有责任去帮助别人，所以成了联合国的维和人员。]
22．B　[然而，“我”觉得这是“我”的责任，帮助陷入困境的无辜的人，所以“我”和联合国签约了。根据文章首句“I've been working as a UN Peacekeeper in the Central African Republic for the past two years．”可知，作者一直在中非共和国担任联合国维和人员，由此可知，作者觉得有责任帮助陷入困境中的人，所以和联合国签约，成了维和人员。]
23．D　[自从20世纪50年代从法国独立以来，政府和叛军之间发生了许多暴力冲突。根据下文“between the government and rebels”和常识可知，中非共和国在20世纪50年代获得了独立，之后内乱不断，政府和叛军发生了许多暴力冲突。]
24．A　[解析同上题，故选A。]
25．A　[2012年，一场内战爆发，100多万人被迫逃离家园，造成多人伤亡。根据上文“a civil war began”可知，内战爆发，人民逃离家园，造成多人伤亡。]
26．B　[作为回应，联合国在该国开展了维和行动。根据下文“the United Nations launched a peacekeeping in the country”以及上文提到的内战爆发，人们被迫逃离家园可知，作为对中非共和国内战的回应，联合国开展了维和行动。]
