9、给的A、B、C、D四个选项中选出最佳选项。A“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 mo
10、re than three times as expensive as in China, it doesnt 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.”A Japanese netizen Kiro Kara said, “I think
11、 the emoji implies very complicated meanings. My dad will send it when he doesnt 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 emoji to tease one another on
12、 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
13、 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). In Everyday Use AbroadIts not the first time the Chinese emoji takes the world sta
14、ge. 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, Yaos 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
15、but are familiar with his emoji and nickname “Chinese Funny Face”.As a new online language, emojis have become a necessary part of peoples daily life, helping people express their views in a more vivid and precise way.

The main purpose of the text is to .A. promote the emoji worldwideB. teach us how to use the emojiC. explain the meaning of emojiD. show us the popularity of the emojiBGarbage often has negative associations with germs (细
18、菌),dirt and useless junk. However, a recent art exhibition proved that “useless” things can have practical significance.Dear Pretty Rubbish, an art event organized by the World Wide Fund for Nature (WWFN) and digital media art company Blackbow, was held in Beijing. It looked at wasteful consumption
19、(消耗) and asked questions about the relationship between our lifestyles and our garbage.“We hope that everyone who visited the show can think about how useless things are produced, why they are tossed out (扔走), and whether useless things are really useless,” said Cao Yujia, the design director of Bla
20、ckbow.The organizers said that all the raw materials for the exhibition were collected from community garbage cans.Artists Zhou Yuxuan and Liu Yifan collected nylon cable ties (尼龙扎带), LED lights and beverage bottles from designers workshops to create a work where plastics, in the shape of cells, “gr
21、ow” in a corner. There, the lights blink (闪烁) regularly to imitate (模仿) “breathing”. When people walk near it, the work responds by forming light patterns, as if communicating with the visitors.Speaking about the work, Zhou said: “Its like some kind of communication between humans and plastics.”Plas
22、tic has a life longer than almost any creature, taking centuries to decompose. Though people blame plastics for damage to the environment, they are a big part of our daily lives.“So we want to ask the question: Although the damage continues, whether there is a way for humans to reconcile (调和) with p
23、lastics,” said Zhou.Liu said that plastic waste can be used to make clothes and ornaments (装饰品). “Re-use of plastics will be a future trend,” he said.Cable ties are a useful and common material for fastening. Many people will buy a large bundle of them but only use a few pieces. The rest of cable ti
24、es could be re-used as a decoration in handicrafts.“This exhibition calls for everyone to re-think their wasteful lifestyle full of single-use plastics and make changes,” said Cao.24.

26、portant for everyone.B. A communitys garbage is full of hidden treasures.C. Creativity can change your life.D. Plastics could be reused to reduce pollution.27. What does the article mainly talk about?A. An art exhibition held in Beijing.B. The rise of a new lifestyle.C. The many uses of plastics.D.
27、An introduction of two artists and their works.CHeart disease is one of the major killers in the world today. Many who suffer from it must have heart transplants (移植). However, its difficult to get a suitable heart donation, and even if a patient survives the wait, his or her body often rejects (排斥)
28、 the heart.But there is now new hope for sufferers of heart disease. According to a study published in the journal Advanced Science, researchers from Israels Tel Aviv University printed a 3D human heart on April 15.“This is the first time anyone anywhere has successfully engineered and printed an en
29、tire heart,” professor Tal Dvir told CNN.Unlike the previous 3D-printed heart structure, the new heart is complete with cells, blood vessels (血管), chambers (心室) and other structures a heart needs to function normally. But scientists still have more to figure out before the 3D-printed heart can be fi
30、tted into the body. For one thing, the experimental heart is only the size of a thumb (拇指). And, although it can contract (收缩) like a muscle, it cannot pump out blood like a real one. At present, the heart prototype (样品) is like a tiny airplane that has all of the right parts, but cant fly.However,
31、the development is still regarded as a major breakthrough in medicine.In the experiment, the researchers turned human fat tissue (脂肪组织) into human heart tissue with stem cell (干细胞) technology. The tissue was then turned into “bio-ink” for a 3D printer to ensure that tissue in the heart came from the
32、 patients themselves. So ideally, if it were to be placed in the body of someone in need of a transplant, there would be less risk of organ rejection.“Patients will no longer have to wait for transplants or take medications to prevent their rejection,” researchers told USA Today. “Instead, the neede
33、d heart will be printed, fully personalized (个性化的) for every patient.”But the scientists think that 3D printing can be used to create other human organs. They foresee a time when the 3D printing of organs will be an everyday medical practice.“Maybe, in 10 years, there will be organ printers in the f
34、inest hospitals around the world and these procedures will be conducted routinely,” Dvir said.28. Why is the 3D-printed heart important?A. It will be used on a patient.B. It is the first 3D-printed heart.C. It will replace a heart donation.D. It has a complete heart structure.29. What problem do 3D-
35、printed hearts have?A. They cost too much.B. They are too small.C. They cant contract.D. They are hard to produce.30. Why would there be less risk of organ rejection with the 3D-printed heart?A. It would be made with stem cell technology.B. It would be made from human fat tissue.C. It would come fro
36、m a patients body.D. It would be printed according to the patients condition.31. What attitude does Tal Dvir hold toward the future of 3D printing of organs?A. Confident. B. Doubtful.C. Worried. D. Confused.DMy love for libraries blossomed when I joined the public library.From the age of 8, I was al
37、lowed to walk from my home to the downtown library, housed above the police station.Once the librarian (图书管理员) gave me my first membership card, I could enjoy a range of books, which started with Little House in the Big Woods.I was addicted instantly, and this love of libraries and reading would cha
38、nge my life, allowing me to one day create a safe space for high-school kids, too.By the time I was in high school, I could read the authors that we were studying in class, including Charles Dickens, Mark Twain and Emily Bronte. During the summer months, I got caught up in Gone with the Wind and Ann
39、a Karenina.When I studied English literature at university, I thought it was time to build my own library. For the next 40 years, I continued to collect books. Until one day, I realized that all my books had become a part of the house, like wallpaper.Toward the end of my teaching career, I became a
40、teacher-librarian at my old high school, where I had first learned English literature. This position resumed (恢复) my love and appreciation for libraries. I never forgot how wonderful it was to be surrounded by books.I had a generous budget (预算) for my classes, so I searched for novels that would int
41、erest my teenage audience and hopefully spark (激发) a love of books. Fantasy, science-fiction, graphic novels I bought almost any type of book that my students wanted to read.I bought sofas and comfortable chairs, turning the library into an inclusive (包容的) public space, safe for everyone.In doing so
42、, I realized that the library isnt just a place to do research. They are, in fact, places that offer an opportunity to engage with the past, present and future. All that is required is a tiny bit of curiosity. Libraries are places that should be full of life. They help us adjust to the world, and th
43、eir doors must be kept open to everyone for free!32.What can we learn about the author during her school time?A. She enjoyed literature very much.B. She didnt have money to buy books.C. She didnt get along well with her parents.D. She usually stayed home during the summer holidays.33. Which of the f

They are places mainly used for research.B. They help people to connect with the world.C. They should be profitable.D. They should be set
45、up mainly in high schools.35. What is the writers main purpose in writing the article?A. To tell readers how to make full use of libraries.B. To tell readers what she learned from books.C. To show her love for reading and libraries.D. To show how much she missed being a teacher.第二节(共5小题;每小题2.5分,满分12

63、y years ago a man rented a store upon a street appropriately named Market Street. While very busy getting barrels, boxes and other things inside, he happened to see a boy of eleven years standing by, and called to him, “See here, boy, if you help me today,Ill pay you well.” The boy looked at him but
64、 made no answer.“Dont you want to work?” The boy made some sort of gesture, but remained silent.“Oh! Youre some lazy, I guess. Well, if you dont work or even speak,just go away.” He thought the boys lazy attitude and continued silence meant disrespect and defiance (蔑视), and soon began to feel angry
65、over it. “Some young thief, I guess, watching his chance to steal something and run,” thought he. Soon he advanced toward the boy with threatening look, when, to his amazement, the boy performed some strange gesture, and strange play of features, as he moved backward.“Ill teach you how to make faces
66、 and mock(嘲笑)me; youve acted the behaviour long enough.” And without further delay he raised his hand, when the boy,instead of running off, started, and fell in a heap (蜷缩)upon the sidewalk.

89、h is certainly not a small sum of money for most people. (18) The collar uses map guiding technology to allow owners to “draw” a line anywhere, including their home, the homes of family and friends, a camp site or a park. If the dog crosses the line, the collar alerts the owner via a mobile phone ap
90、p and helps him track and find the dog, (19) even in remote areas like forests. The collar makes two noises, followed by a mild electric shock to tell the dog to go back. Products which give shocks to pets are sometimes unpopular. Electric collars used for training are illegal in the UK, but the maker of this invention hopes to put it on sale in the US in around a years time. (20)
