第二部分、阅读理解：（共两节，每小题2分，共计30分）
第一节：(共10小题；每小题2分，满分20分)
阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。
A
My son ,Izzy, was a nine-year-old boy and had been begging me to please let him find his way home by subway, by himself. After all, we live in New York City,and getting around by public transportation is a basic part of life. It is also the first step toward feeling grown-up. So on that sunny Sunday，I gave him a subway map, a transportation card,$20 for emergencies, and a couple of coins so that he could call me if necessary.
I didn’t give him a cell phone because nine-year-olds lose things. A few days later, I wrote about his adventure，or non-adventure for a newspaper. Little did I realize the idea that a kid could tour the city on h is own, and that a mom would let him, was big news.
It turned out that many TV shows called me and asked for an interview. Bloggers were going crazy, so I started a blog, too, and letters came pouring in. Finally I found out why this was such a big story: we have become fearful for our children. Fear is hardly a new thing for parents ,of course. But the fear of letting our children out of sight for even a second-that’s new. How did this happen? How did it become too scary to let kids be kids? I asked the question when the reporter Trevor Butterworth interviewed me.
“News reports,”he answered .”News reports scare the pants off you. What is scarier than a kidnapped(绑架) kid-no matter how far away？Because there are so many such stories, it starts to feel as if kidnappings are happening all the time. That’s why the kid-on-the-subway story surprises the whole wo rld.”
Izzy probably did a good job. He simply proved that kids could leave home alone and return home safely !But he didn’t think it was a big deal .”It was fun,”he said. ”But I missed some classes because of the interviews.”Sometimes it really pays to be brave.
21．Why did the author let her son take the subway alone?
A. Because she always let her son do whatever he wanted.
B. Because she believed that her son had memorized the subway map.
C. Because she thought it would be big news around the whole world.
D. Because she felt traveling by subway in New York was a basic life skill.
22．The author gave her son all the following when he traveled alone EXCEPT_______.
A. a map.
B. a cell phone.
C. a transportation card
D. some money. 23．The author didn’t expect that after she wrote her son’s story for a newspaper, __________.
A. a blog would be started in her name
B. her son would receive so many letters
C. many TV shows would want to interview her
D. many TV stations would want to film her son’s story
B.
Several weeks ago, kidsPost did a story on “The Art of Video Games” at the Smithsonian American Art Museum. The exhibition has created debate with some people saying that as fun as video games are ,they are not works of art. Other people say that videos games may be a new form of art and that they belong to in museums. We asked readers for their opinions on the topic. Here are a few of the letters we received.
A video game is like a painting on a screen. In order to make a video game, you have to think of something original(新颖的)to reach the players. This is the point of Art.
---Mary Pottanat,13
I believe video games are not a form of art. Art should be a visual (视觉的)and creative expression of feelings. Although it is arguable that video games are visual ,they do not express feelings in any way.
---Prannab Kirshnan,12
However exciting video games are, they are not art. Painting is art, but not video games. Art has beauty and culture that no technology could ever compare to. Even though you can create art in some video games, the “Mona Lisa”wasn’t painted with Nintendo.
---Caroline Kaplan,10
Art is a way of communicating ideas to the public in a way that is fun to them. The “public”, who in this case are kids and adults, are finding these video games
from different time periods interesting. Video games would not have been ar t if it had not been for the kids and adults attracted by “the art of video games”.
---Ryan Puthumana,10
24．Who’s the author?
A. An artist.
B.A video game creator.
C. Someone who works at KidsPost.
D. Someone who works in a museum. 25．Ryan Puthumana holds the view that video games________.
A. aren’t fun enough to be art.
B. are so interesting that they are art.
C. can’t express feelings as well as art.
D. are not so popular with kids as before.
26．We can learn from the text that ______.
A. Caroline Kaplan disagrees with Mary Pottanat.
B. Only one kid thinks video games are similar to art.
C. Prannab Kir shnan doesn’t like playing video games.
D. The older the kids are ,the more they like video games.
27．The text mainly discusses____________.
A. the differences between video games and art.
B. why people like or hate video games.
C. whether video games are art or not.
D. what can be considered works of art.
C.
In the history of Hawaii, surfing is a serious thing. Ancient leaders used the sport as a training exercise to keep themselves strong. They also used surfing competitions instead of wars to solve conflicts between people. For a long time ,this tradition of surfing was known mainly to the people of Hawaii. Then Duke Kahanamoku came along and changed the world.
When he was 21years old, Duke broke two world swimming records. Not surprisingly, Duke easily made the Olympic swimming team in 1912.During his Olympic career, Duke won three gold medals and two silver medals in swimming.
When Duke finished winning medals at the Olympics, he toured the world. He also brought along his surfboard. Duke had been surfing ever since he was a little boy. In 1917,he rode
a single wave for more than a mile! Duke amazed people by riding his 16-foot-long board. He is considered the father of modern surfing.
Since Duke was handsome and strong, people loved to watch him. His next career move was clear. Duke headed for Ho llywood. From 1925 to 1955,he made more than 30 movies.
One day in 1925, Duke and a few other surfers were hanging out on the beach when a boat turned over not far from them. The surfers hit the waves with their big boards and saved 12 of the passengers. Duke alone saved eight of them! After that, lifeguards at beaches started using surfboards to save swimmers. Helping others was a big thing in Duke’s life.
In 1932,Duke became sheriff(治安官)of Honolulu, Hawaii, holding the position for almost 30 years. As sheriff, in fact, his job was to greet visitors who came to the city .From the Olympics to Hollywood, Duke Kahanamoku had put Hawaii on the map when it was still a little known island.
When he was 75 years old, Dukes name was added to both the Swimming Hall of Fame and the Surfing Hall of Fame. He died in 1968 at the age of 78.
28．The first paragraph serves as a(an)_______.
A. explanation
B. introduction
C. comment
D. background 29．What can we infer about Duke according to paragraph 5?
A. He was modest and honest.
B. He was clever and confident.
C. He was brave and kind-hearted.
D. He was generous and open-minded. 30．What is the text mainly about?
A. The development of Hawaii.
B. The achievements of Duke.
C. T he personal life of Duke.
D. The history of surfing.

三、完型填空（共20小题；每小题1分，共计20分）
Each of us has goals for life. Some of these may be long-term (长期的) or 36 lifetime ones, and other dreams or wishes for more immediate satisfaction.
Just as you 37 great pleasure when you’re trying to 38 short-term goals, there’s also power in having long-term and lifetime goals. Both 39 are valuable and serve each other. In order to be 40 in achieving a short- or long-term wish or goal, you must place your focus on the 41 result and train your mind on either a moment-to-moment, day-to-day, month-to-
month, or year-to-year level.
For example, 42 a farmer is to plow (耕地) a straight line, he must keep his eye on a faraway point. If his attention is 43 just a few feet in front of him, he will not plow straight. So, in order for his field to be plowed straight, he must 44 and focus on his long-term goal.
Focusing on a long-term goal can 45 the energy to get things done in the 46 . For instance, when a runner sets a(n) 47 to run a mile, he’ll 48 be tired when he 49 the one-mile mark. 50 if this same runner sets a goal to run ten miles, he
probably won’t even be sweating (出汗) upon 51 this same one-mile mark. If this very same runner was to set a goal to run 26 miles and keep his mind on the completion of this long 52 , not only wouldn’t he be sweating, but most likely he wouldn’t even be out of breath as he ran by the 53 mark.
Long-term goals, 54 , can’t be achieved without first achieving 55 goals. We may have a goal to climb a ladder (梯子), but we have to take one step at a time in order to reach the top.
36. A. even B. just C. also D. rather
37. A. understand B. experience C.
explain D. welcome
38. A. set B. keep
C. prevent
D. achieve
39. A. terms B. dreams C. types D. thoughts
40. A. successful B. special C. interested D. different
41. A. important B. certain C. final D. happy
42. A. if B. when C. although D. because
43. A. received B. attracted C. dir ected
D. paid
44. A. correct B. forget C. believe
D. know
45. A. choose B. influence C. report D. provide
46. A. dark B. present
C. end
D. future
47. A. date B. story C. goal
D. example
48. A. probably B. person ally C. partly
D. quietly
49. A. remembers B. reaches C. discovers
D. records
50. A. And B. But C. So
D. Or
51. A. waiting for B. searching for C. preparing
D. passing
52. A. race B. game C. drive
D. flight
53. A. twenty-six-mile B. thirteen-mile C. ten-mile D. one-mile
54. A. however B. besides C. instead D. therefore
55. A. lifetime B. short-term C. common
D. big

银川一中高一期末考试语文试卷 班级＿＿＿姓名＿＿＿学号＿＿ 一、现代文阅读 阅读下面的文字，完成1～3题。（9分，每小题3分） 茶文化源远流长。据传茶的发现约于公元前2700多年的神农时代。最早祖先们利用的是野生茶树，人工栽培约在3000多年前，巴蜀地区是中国茶树的起源地之一。东晋史书《华阳国志·巴志》记载，周武王伐纣时，巴蜀一带已用当地所产茶叶作贡品，说明当时茶叶生产已有一定规模。而后茶的栽培从巴蜀地区南下云贵，东移楚湘，转粤赣闽，入江浙，北移淮河流域，形成广阔的产茶区。 原始社会人类在对植物的长期食用中发现茶树叶有解渴、提神和治疗某些疾病的作用，就把它熬煮成茶水作饮料。长期以来，茶只是用来治病，大约到西周初期，茶叶才发展为茶食，即“生煮羹饭”，后又成为祭品，最终从煮水清饮改进到泡饮。 秦以前，各地语言文字不统一，茶的名称众说纷纭。商周时茶叶首次有了名字，叫“荼”，因其苦涩，又叫“苦荼”。据唐代陆羽《茶经》载，唐以前，茶有“荼”、“贾”等名，自《茶经》问世后，正式将“荼”字减去一横，称之为“茶”。 春秋战国时期，茶叶已传至黄河中下游地区。清代顾炎武在《日知录》中说：“自秦人取蜀而后，始有茗饮之事。”到了汉代，茶的保健作用日益受到重视。西汉王褒在《僮约》中提到“武阳买荼”，说明当时已有了专卖茶叶的茶叶市场。魏晋南北朝时期，饮茶的风气传播到长江中下游，茶叶已成为待客、宴会、祭礼的饮料。南齐武帝临终遗诏说：“灵座上慎勿以牲为祭，惟设饼、茶饮、干饭、酒脯而已。天下贵贱，咸同此制。”从此茶叶成为祭祀时必备的祭品。 唐代中期，饮茶之风盛行全国。各地制茶技术日益提高，出现很多名茶。有关茶的诗歌众多，据统计，李白、杜甫等100多人写了400多篇涉及茶事的诗歌，唐代还首次出现描绘饮茶场面的绘画。宋代，茶成为普及的饮料，特别是上层社会嗜茶成风。制茶的技术达到了精巧奢华的地步，如龙凤团饼茶的制作技术就非常复杂，有蒸茶、榨茶、研茶、造茶、过黄、烘茶等工序。1391年，明太祖下诏“罢造龙团，惟采茶牙以进”。皇室提倡饮用散茶，民间蔚然成风，并将煎煮法改为冲泡法，这是饮茶方法史上的一次革命。明代茶的加工炒制方法和品饮都有了创新，出现了炒青技术和功夫茶艺，从而推动了名茶发展和许多茶类的创新。 茶自发现以后，通过各种渠道传向国外。目前世界上50多个产茶国的茶种、饮茶风尚都来自中国。中国茶叶约在汉代就传入日本，唐代又有大批日本僧人来华，回国时带回茶种。中国茶叶传入欧洲是在1607年。东印度公司成立的第二年，荷兰船首次将茶由澳门转运到爪哇。1669年，英国印度公司把14万磅茶叶运到英国，当时只在伦敦咖啡馆中供应少量中国茶。17世纪初明神宗万历年间，中国大使将少量茶叶运入俄国，大量输入是在1689年签订《尼布楚条约》后，1893年，俄国聘请中国茶工发展茶叶生产。此后中国茶叶又从欧洲和中国传入了东南亚各国。 1. 下列选项与原文意思不相符的一项是（） A. 西周时，作为中国茶树的起源地之一的巴蜀地区的茶叶生产已有一定规模，所产茶叶已作为贡品。 B. 西周初年，茶叶的功用由治病发展为泡饮，其间经历茶食、煮水清饮和祭品三个发展阶段。 C. 西汉时已有了专卖茶叶的茶叶市场，茶的保健作用日益受到重视。 D. 魏晋南北朝时，饮茶的风气已传至长江中下游，茶叶成为祭祀时必备的祭品。 2. 中国茶“通过各种渠道传向国外”，对“各种渠道”表述正确的一项是（）
