第二节完形填空（共20小题；每小题1.5分，满分30分）
Enjoy your own life without comparing it with that of another
——Marquis de Condorcet
If you took the strengths of others, and compared them to your weaknesses, do you think this would make you feel good? The funny thing is, this is 36 most of us do at one time or another—and some of us do pretty 37 .
It’s surely a practice for a(n) 38 in self‐confidence and for unhappiness. Let’s say I take a
look at someone who creates 39 artwork on their website and I look at my art, and realize I don’t come _40 _ to being matched with him. In fact, I look pretty pitiful. But it’s not a fair 41 . If I looked at my strengths—writing useful and honest posts—I can see that I have a lot to offer, a lot to be happy about.
That’s so important—being able to look at your own strengths, and see your true 42 . It’s actually one of the 43 to success and happiness.
I want to talk about this issue 44 an email from a reader recently: I have some teammates
from very rich families, I can’t stop myself comparing my lifestyle with 45 . I must say that my 46 planning is sound enough to take care of my existing family; and I can take care of new
family members also, at least for 47 even if I lose my current job. But 48 I see or hear them spending so much money after possessions, I start comparing 49 . How can I stop this habit, without changing jobs?
This is an excellent but tough 50 . I think it’s 51 to compare ourselves to others, but it often makes us unhappy even if we have enough and 52 be happy with what we have. My quick advice: try to be aware of when you start comparing yourself to others… once you’ve
developed this 53 , stop yourself and tell yourself, “Stop that!” And then 54 thinking about
all the things you do have, the things you love, the people you have and the blessings that 55 has given you. Make this a regular practice, and you’ll start to be happier with your life.
36. A. why B. what C. that D. how
37. A. often B. seldom C. usually D. always
38. A. rise B. increase C. drop D. failure
39. A. astonished B. disappointing C. shocked D. amazing
40. A. up B. close C. down D. closely
41. A. comparison B. communication C. competition D. connection
42. A. strengths B. shortcomings C. values D. weaknesses
A. reasons
B. keys
C. causes
D. means
44. A. because of B. regardless of C. in spite of D. in case of
45. A. them B. their C. themselves D. theirs
46. A. financial B. annual C. special D. beneficial
47. A. sometime B. some time C. some times D. sometimes
48. A. however B. whatever C. wherever D. whenever
49. A. then B. later C. again D. thus
50. A. question B. person C. phenomenon D. reader
51. A. strange B. natural C. difficult D. important
52. A. must B. can C. may D. should
53. A. awareness B. hobby C. tradition D. custom
54. A. stop B. help C. come D. start
55. A. happiness B. life C. success D. confidence

A thief who dropped a winning lottery ticket at the scene of his crime has been given a
lesson in honesty. His victim, who picked up the ticket, then claimed the $25,000 prize, managed to trace him, and handed over the cash. The robbery happened when maths professor Vinicio
Sabbatucci, 58, was changing a tire on an Italian motorway. Another motorist, who stopped “to
help”, stole a suitcase from his car and drove off. The professor found the dropped ticket and put it in his pocket before driving home to Ascoli in eastern Italy.
Next day, he saw the lottery results on TV and, taking out the ticket, realized it was a winner. He claimed the 60 million lire(里拉)prize. Then he began a battle with his conscience. Finally, he
decided he could not keep the money despite having been robbed. He advertised in newspapers and on the radio, saying, “I’m trying to find the man who robbed me. I have 60 million lire for him—a lottery win. Please meet me. Anonymity(匿名)guaranteed.”
Professor Sabbatucci received hundreds of calls from people hoping to trick him into
handing them the cash. But there was one voice he recognized and he arranged to meet the man in a park. The robber, a 35‐year‐old unemployed father of two, gave back the suitcase and burst
into tears. He could not believe what was happening. “Why didn’t you keep the money?” he
asked. The professor replied, “I coul dn’t because it’s not mine.” Then he walked off, spurning the thief’s offer of a reward.
61. The sentence “Then he began a battle with his conscience.” in Paragraph 2 implies all of the following except that _________.
A. he knew what he should do as soon as he saw the lottery results
B. he hesitated about keeping the money for some time
C. he thought for a moment of avenging himself on the robber
D. he came to realize that honesty is more important than money
62. Hundreds of people phoned Professor Sabbaturcci because they _________.
A.wanted to make fun of him
B. hoped to get the money
C. knew who the robber was
D. lost the lottery ticket
63. How did the robber feel when the victim wanted to find him?
A. Excited
B. Frightened
C. Ashamed
D. Incredible
64. The word “spurning” in the last sentence can be replaced by __________.
A. accepting
B. claiming
C. rejecting
D. cancelling
65. If the story appears in a newspaper, the best title might be __________.

Styrofoam, or polystyrene, is a light-weight material, about 95 percent air, with very good insulation(隔热) properties, according to https://www.doczj.com/doc/4911169743.html,. It is used in products from cups that keep your drinks hot or cold to packaging material that protects items during shipping.
With the above good features, Styrofoam still enjoys a bad reputation. It cannot be recycled without releasing dangerous pollution into the air. The U.S. Environmental Protection Agency says it is the fifth-largest creator of harmful waste.
But now the common worms which are usually disgusting can come to the rescue, specifically, mealworms. Scientists from the U.S. and China have discovered that mealworms can
digest plastic. One mealworm can digest a pill-sized amount of plastic a day. Study co-author Wei-
Min Wu says that in 24 hours, the plastic is turned into carbon dioxide.
Since Styrofoam has no nutrition at all, are the worms hurt by eating plastic? Much to the scientists’ surprise, the study found that worms eating Styrofoam were as healthy as worms eating
bran(谷糠).
The researchers will study the worm’s eating habits and digesting system, looking to copy the
plastic breakdown but on a larger scale. Once the way can be put into practice, it will make a revolutionary difference to the disposal of plastic.
“Solving the issue of plastic pollution is important”, says Wu, a Stanford University environmental engineering instructor. After all, our earth is small and landfill space is becoming limited with too much garbage waiting to be dealt with, he says.
About 33-million tons of plastic are thrown away in the United States every year. Plastic plates, cups and containers take up 25 percent to 30 percent of space in America’s landfills. One
Styrofoam cup takes more than 1 million years to recycle in a landfill, according to Cleveland State University.
66. What do we know about Styrofoam?
A. It can be used to cool drinks.
B. It is a weightless material.
C. It is harmful when recycled.
D. It is usually used on ships.
67. What can we infer from the third paragraph?
A. Mealworms have amazing digesting power.
B. Mealworms are not bad in their nature.
C. Mealworms can rescue people’s lives.
D. People misunderstood mealworms in the past.
68. Why will researchers study the worm’s eating habits and digesting system?
A. To find ways to help mealworms grow larger.
B. To imitate their ways of breaking down plastic.
C. To help develop their digesting ability.
D. To make sure of their safety after eating plastic.
69. In the future, plastic may be recycled ________.
A. by raising amounts of mealworms
B. by environmental engineering instructors
C. using a method inspired by eating mealworms
D. without sending out dangerous pollution
70. What’s the main idea of this passage?
A. Styrofoam is widely used in daily life.
B. Mealworms are genius at eating plastic.
C. Plastic recycling may be no more a problem.
D. Plastic can be turned into carbon dioxide.
D
I can tell you from experience, both private and public schools have one thing in common. Look arou nd your school. What do you see? Beautiful buildings? Good teachers? I’ll tell you what
I see: the need to have the most expensive clothing, newest phone, most expensive car, etc. Think
about it. Do you find yourself wanting to one-up(胜过)your friends? Be honest. I know I have at
some point in time.
In my school parking lot, for example, there are more BMW’s and Mercedes than one
could possibly imagine. When I look at my 2006 Honda CRV, the butterflies in my stomach start flapping their wings wildly. Do people look at me differently because my car is old?
What about my phone? What about text messaging? Earlier this year in my statistics class my teacher asked our class how many texts each student received in the past 24 hours. My count
was twelve. Twenty minutes later, people started to come up with the answers of 200 or more. I
firmly believe that people were in competition with each other. Who could get the most texts? Having only twelve texts sent to me made me feel terrible. Was it bad that hardly anyone had texted me? My teacher would never have thought that his question which intended a better understanding of the course made me uncomfortable.
How about the difference between grade levels in high school? Come on. There is a distinct difference from being a senior and a freshman. At gatherings, the senior class boos(喝倒
彩)every other grade, sometimes causing fights. Being a senior, I don’t want to make negative comments on people in other grade levels. High school is hard enough as it is. Freshmen, sophomores and juniors don’t need four hundred students to remind them.
Trying to impress everyone is hard. Most of the stress we have as teens is living up to everyone else’s expectations. The only people we need to impress are ourselves. Be in competition
with yourself and you’ll live a happier life.
71. What is the comon thing beteen private and public schools according to the writer?
A. Good teaching resourses.
B. Great need for advanced technology.
C. Students’ competition for material things.
D. Having a beautiful environment.
72. How does a person feel if he has a butterfly in his stomach?
A. Proud.
B. Nervous.
C. Confident.
D. Angry.
73. Why did the teacher ask the students about the number of the texts they received?
A. It was connected with what he was teaching.
B. He wanted to learn about their social habits.
C. He wanted to make his class interesting.
D. He tried to stop them texting in his class.
74. We can learn from the fourth paragraph that _________.
A. the writer finds it hard to get on well with others
B. the writer is a considerate person
C. students in lower grades should be reminded to behave well
D. fights and quarrels are common between different grades
75. To live a happier life, teens are advised _________.
A. to stop buying expensive things
B. to do things as they are expected
C. to leave a good impression on others
D. to stop competing with others
第II卷（非选择题，共35分）
第一节阅读表达（共5小题；每小题2分，满分10分）
阅读下面短文，并根据题目要求用英语回答问题（请注意问题后的字数要求）。
I’m not an athlete, but I am a lover of the Olympics. My biggest sports moment ever didn’t require me to be the fastest, the highest, or the strongest. It just required me to be in the right place at the right time, and catch the opportunity when it came to me. It was to carry our national flag for the Olympic Torch Relay.
As a part of the celebration, flag bearers(旗手)were needed. I served in the army at that
time and the Olympic organizers asked for volunteers to help carry some of the flags. Although it
demanded that I give up part of my weekends and get up early, I thought that it was the chance of a lifetime.
There were several different groups that took part in the event as flag bearers. We
soldiers were going to be out in front leading them. On the day of the event, we arrived early at the Los Angeles Memorial Coliseum. Many people arrived to see the flame arrive from Greece, and the beginning of the Olympic Torch Relay. It was exciting to wait for our turn to enter the coliseum.
As a flag bearer, I was supposed to run out in front. Though the flag was fairly heavy, I picked it up and ran with it. I ran past rows of people. I ran through television cameras. It was one of the most amazing experiences of my life, being able to carry our national flag in an international event like the Olympics. I was very proud of it.
I had never been able to attend the Olympics, and I might never be important enough to carry an Olympic torch or anything like that, but I did get to carry our national flag in the torch relay, although I will no longer have the opportunity to carry the flag in the Olympics, and that would be one sports experience that would be difficult to forget.
76. What was the author when the Olympics were hosted in Los Angeles?
(no more than 6 words)
_________________________________________________________________________ 77. What was the author asked to do as a volunteer? (no more than 10 words)
__________________________________________________________________________ 78. What’s the meaning of the underlined sentence in Paragraph 2? (no more than 10 words)
__________________________________________________________________________ 79. How many times has the author carried the flag in the Olympics?
(no more than 2 words)
__________________________________________________________________________ 80. Do you want to be a flag bearer? Why or why not? (no more than 20 words)
__________________________________________________________________________

Dear He Fei，
I’ve received your letter and deeply understand how you feel now. However, don't be disappointed or even doubt yourself as you are not the only one who finds it difficult to
write well. I suppose the following suggestions might be of some help to you.
To begin with, it is essential to memorize some words, phrases as well as sentence structures, because they are the basis of language learning, just like bricks in a building. Additionally, read English article?such
as possible and recite the good ones so that you may know how to put them to use whenever possible. Last but not least, keep in mind that
there are many things that can't be learnt immediately, so never be frustrated when you fail in one or two exams.
Anyway, just keep going with a strong belief that you can improve your written English
as long as you never give up. Just as the saying goes: “Practice makes perfect.”
Yours,

炎德?英才大联考长沙市一中2017届高三月考试卷（三） 命题人：欧鹏举成特立蓝黄审校：周玉龙黎奕娜本试卷分第Ⅰ卷（阅读题）和第Ⅱ卷（表达题）两部分，时量150分钟，满分150分 第Ⅰ卷（阅读题，共70分） 一、现代文阅读（9分，每小题3分） （一）论述类文本阅读（本题共3小题，共9分） 阅读下面的文字，完成1-3题。 近几年网络文艺异军突起，网络小说、网络自制剧、网络大电影、网络综艺、网络游戏、网络动漫的呈现巨大的市场生命力，正抢占传统文艺市场。。 然而，相对于发展了几十年甚至上百年的传统文艺，网络文艺还是一个新概念，无论是业界还是学界仍未给出一个权威的统一清晰的界定，更别提系统科学的研究了。有学者从广义上归纳网络文艺的内涵，认为网络文艺是指具有网络精神的文艺作品，因此只要具备一定互联网因素的文艺作品都可以称为网络文艺，其中包括在互联网上传播的传统文艺作品；也有学者把网络文艺狭义地理解为以数字化形式进行生产创作，并在互联网上进行传播的文学和艺术作品。对于网络文艺与传统文艺之间的关联更是仁者见仁，智者见智。一种说法认为，网络文艺是传统文艺在网络上的延伸，旨在强调传统文艺与网络文艺都为文艺，即文艺本质论；另一种说法认为，网络文艺是传统文艺的补充，旨在强调网络文艺能够传达传统文艺之外的内容，丰富文艺的表现方式；还有一种说法认为，网络文艺完全独立于传统文艺之外，旨在强调网络文艺是一种基于网络技术语言的多媒介因素相互渗透而形成的新型文艺，与传统文艺有着天然的鸿沟。这些观点尽管具有一定合理性，但仍有失偏颇。因为网络文艺和传统文艺之间既存在天然的有机联系，又具有本质区别。 网络文艺既不是传统文艺在网络上的延伸，也不仅仅是传统文艺的补充。网络文艺与传统文艺就像两个有交集的集合，既有藩篱也有突破，既交融又交汇。从本质看，网络文艺与传统文艺只是媒介载体不同而已，那些经历过无数前辈提炼和检验的传统文艺创作和传播的基本规律、审美价值和文艺理论依然适用于网络文艺。由于技术带来的文艺内在特征和审美方式的质变，网络文艺突破了传统文艺内容和形式的限制，拥有传统文艺无法比拟的优势，隐含符合新媒体时代要求的内在规律。但必须承认的是，网络文艺尚处于发展初级阶段，形态和特征并未完全展现，很难完全厘清与传统文艺之间的内在关联。因此，对两者关系的认知和把握应采取辩证的、长远的眼光和态度：一方面肯定两者的天然联系，但又不能将两者混为一谈；一方面承认两者的本质区别，但又不能将网络文艺视为独立的文艺类型；一方面
