Dear listeners,
Each month on Instagram, we suggest a photo assignment for our project Public Square. For this month’s assignm ent, we wanted to see your commute(通勤，上下班) —that perfectly average and ordinary part of the day that many of us share and 16 you to find beauty in it. Many of you rose to the 17 . And one photo 18 had a special story.
Amateur photographer Jabali Sawicki commutes by 19 from Brooklyn into New York’s Penn Station every morning. But on a recent return trip home he noticed something 20 with the assignment in mind:
―It was 21 all of New York City had vanished into the background,‖ he says. ―All the noise and chaos of the subway and commute had 22 . And all that was left was a mother and her son 23 .‖Sawicki captured the 24 , shared it, and then likely forgot about it.
The mother, it turns out, was Megan Freund, who commutes every day with her young son, Eli. Eli goes to day care near where his mother works as a teacher.
Shortly thereafter, Freund was scrolling through some of the Instagram commute photos we 25 here, when she saw the picture Sawicki had taken 26 her and her son on the train: ―I started crying 27 I was so overwhelmed,‖ she says. ―He’s sort of curled up next to me and I’m reading him a book about dinosaurs, actually, my father had given to me when I was 8 years old for Christmas. It was pretty 28 that somebody had noticed that moment.‖
She left a comment on the blog and also left a comment 29 Sawicki on Instagram.
―I probably read it four times30 I realized what was happening,‖ he says. ―The fact that 31 miraculously she had found this picture and that it 32 so much to her.‖
He mailed a 33 of the photo to Freund.
―It’s a really nice 34 ,‖ says Freund, ―especially when the days are long, the commutes are long ... we’re so fortunate to have this time together.‖
The photo is available on Instagram under the title ―Giving the gift of reading.‖, displaying a magical moment between mother and son. It may seem like just another subway ride, but with a book and a(n) 35 , the adventures are limitless.
Keep an eye out for the next Public Square assignment on Instagram!

三．阅读理解
A
The power of humor and laugher is numerous. They entertain us and make us feel good. But,
above all, we have discovered that humor and laughter are the best medicine. They relieve pain, reduce stress and anxiety, and are anti-aging and longevity facilitators（促进者）.
They are extremely necessary for helping us to find and maintain a balance between life and work. However, they are slipping away from us. We have become far too serious. The only ones who still enjoy humor, laughter, fun and play to the fullest are young children. Children tend to laugh an average of 200 times a day. For adults, however, it is a totally different story.
In the 1950s people laughed on average 18 times a day. Today, we are lucky if we average between 4-6 times a day.
As a matter of fact, a recent study found that people laugh 6 more times in the presence of one person but 30 more times in a group of people. You can get a chuckle(咯咯笑) from jokes you get on the Internet, but it is not the same as belly jiggling laughter (a deep laugh) you get when you interact with others.
Socializing(交际) with friends and relatives was much looked forward to. However, this is no longer the case. In fact, the majority of people can hardly find time, nor do they have the inclination towards socializing outside home. They turn to electronic media such as television, computers, the Internet, videos, CDs, and audio equipment, which can provide them with instant self-entertainment at the push of a button.
The workplace does not fare(进展) much better. Due to the pressures to produce more in the same or fewer hours available and to compete, for example, in a manufacturing field with cheaper labor elsewhere in the world, humor and laughter in the workplace have gradually eroded（逐渐毁坏）away.
I have developed a real appreciation, perhaps closer to a strong desire for the power of humor and laughter. This encouraged me to write my first book titled ―The Power of Humor‖ and subsequently my second book titled ―Kids Say the Goggonest Things‖ base d on the natural humor, laughter, play and fun that kids experience and they freely share with parents, grandparents and teachers.
From writing about humor and laughter, people start to ask me to speak up for them. To date, I have developed a number of humor-laughter topics that I use in my keynote presentations. You are invited to subscribe to my free monthly e-magazine ―The Humormeister’s Forum‖ by clicking on the Free Humor E-zine navigation button on the website.
36. According to the author, laughter is leaving us partly because ________.
A. the pace of change in our lives is becoming faster
B. we fail to reflect on fun times in our lives
C. we treat everything in a serious way
D. humor of situations lies beneath
37. The fourth paragraph mainly tells us that ________.
A. researchers have made a new discovery about the effect of laughter
B. people laugh more heartily when spending time with others
C. we can entertain ourselves with the help of the Internet
D. getting a deep laugh nowadays is difficult
38. The underlined word ―inclination‖ in Paragraph 5 most probably means ―________‖.
A. destination
B. tendency
C. attitude
D. approach
39. Which of the following articles can we most probably find in ―The Humormeister’s Forum‖?
A. The power of honesty.
B. Don’t be your own worst enemy.
C. Live life purposefully: The relationship within.
D. Funny Christmas stories to share with your loved ones.
B
Learning a foreign language is never easy --- but it’s a lot harder if you f all into these five common snares.（陷阱）
1. Not listening enough
There’s a school of linguistics（语言学）that believes language learning begins with a ―silent period‖. Just as babies learn to produce a language by hearing and repeating sounds, language learners need to practice listening in order to learn. This can improve learned vocabulary and structures and help learners see patterns in language.
2. Lack of curiosity
In language learning, attitude can be a key factor in how a student progresses.
Linguists studied attitude in language learning in the 1970s in Quebec, Canada, when tension was high between Anglophones (English-speaking people) and Francophones (French-speaking people). The study found that Anglophones holding prejudices against French Canadians often did poorly in French language learning, even after studying French for years as a mandatory school subject. On the other hand, culturally curious students will be more receptive to the language and more open to forming relationships with native speakers.
3. Rigid thinking
Linguists have found that students with a low tolerance of ambiguity tend to struggle with language learning. Language learning involves a lot of uncertainty –students will encounter new vocabulary daily, and for each grammar rule there will be a dialectic exception or irregular verb. Until native-like fluency is achieved, there will always be some level of ambiguity.
Learner who see a new word and reaches for the dictionary instead of guessing the meaning according to the context may feel stressed. Eventually, they might quit their language studies out of frustration.
4. A single method
Some learners are most comfortable with the listen-and-repeat drills of a language lab or podcast. Some need a grammar textbook to make sense of a foreign tongue. Each of these approaches is fine, but it’s a mistake to rely on only one.
Language learners who use multiple methods get to practise different skills and see concepts explained in different ways. What’s more, the variety can keep them from getting stuck in a learning rut （老一套）.
5. __________
It doesn’t matter how well a person can write in foreign script, conjugate a verb, or finish a vocabulary test. To learn, improve, and truly use your target language, we need to speak. This is the stage when language students can clam up, and feelings of shyness or insecurity hinder all their hard work. In Eastern cultures where saving face is a strong social value, EFL teachers often complain that students, despite years of studying English, simply will not speak it. They’re too afraid of bun gling the grammar or mispronouncing words in a way that would embarrass them.
40. The author mentions Anglophones and Francophones in order to show ________.
A. Canada is a mixed country.
B. interest in language learning is important
C. there is competition between Anglophones and Francophones
D. Anglophones held prejudices against Francophones
41. Learners with a curiosity in foreign cultures _________.
A. need a grammatical rules to understand a foreign language
B. are more willing to get exposed to relationships with native speakers
C. are not afraid of making pronunciation mistakes
D. would like to pracitse listening in order to achieve fluency
42. Which of the following can be used to fill in the blank?
A. Ignorance of cultural differences
B. Incorrect pronunciation
C. Improper use of language
D. Great fear for embarrassment
43. What’s the author’s purpose in writing this text?
A. To present the recent study on language learning
B. To explain why the five mistakes happen
C. To give us some advice on language learning
D. To offer some tips on self-study
C
I was born under the Blue Ridge, and under that side which is blue in the evening light, in a wild land of game and forest and rushing waters. There, on the borders of a creek that runs into the Yadkin River, in a cabin that was chinked with red mud, I came into the world a subject of King George
the Third, in that part of his realm known as the province of North Carolina.
The cabin smelt very strongly of corn-pone and bacon, and the odor of pelts. It had two shakedowns(临时床铺), on one of which I slept under a bearskin. A rough stone chimney was raised outside, and the fireplace was as long as my father was tall. There was a crane in it, and a bake kettle; and over it great buckhorns held my father’s rifle when it was not in use. On other horns hung jerked bear’s meat and venison hams, and gourds for drinking cups, and bags of seed, and my father’s best hunting shirt; also, in a neglected corner, several articles of woman’s clothing. These once belonged to my mother. Among them was a gown of silk, of a fine, faded pattern, which I always wondered. The women at the Cross-Roads, twelve miles away, were dressed in coarse butternut wool and huge sunbonnets. But when I questioned my father on these matters he would give me no answers.
My father was—how shall I say what he was? To this day I can only surmise many things of him. He was a Scotchman born, and I know now that he had a slight Scotch accent. At the time of which I write, my early childhood, he was a frontiersman and hunter. I can see him now, with his hunting shirt and leggins (绑腿) and moccasins（莫卡辛鞋）; his powder horn, engraved with wondrous scenes; his bullet pouch and tomahawk and hunting knife. He was a tall, lean man with a strange, sad face. And he talked little except when he drank too many ―horns,‖ as they were called in t hat country. These little bad behaviors of my father’s were a permanent source of wonder to me—and, I must say, of delight. They occurred only when a passing traveler who hit his fancy chanced that way, or, what was almost as rare, a neighbor. Many a winter night I have lain awake under the skins, listening to a flow of language that held me spellbound, though I understood scarce a word of it.
―Virtuous(有德行的) and vicious(罪恶的) every man must be,
Few in the extreme, but all in a degree.‖
The chance neighbor or traveler was no less struck with wonder. And many the time have I heard the query, at the Cross-Roads and elsewhere, ―Whar Alec Trimble got his larnin’?‖
44. The mention of the dress in the second paragraph is most likely meant to _____.
A. show the similarity between its owner and other members of the community
B. show how warm the climate was
C. show the dissimilarity between its owner and other members of the community
D. give us insight into the way most of the women of the region dressed
45. Judging by the sentences surrounding it, the underlined word ―surmise‖ in the third paragraph most nearly means _____.
A. to form a negative opinion
B. to praise
C. to desire
D. to guess
46. Why did the narrator enjoy it when his father drank too many ―horns,‖ or drafts of liquor?
A. The father spoke brilliantly at those times.
B. The boy was then allowed to do as he pleased.
C. These were the only times when the father was not abusive.
D. The boy was allowed to sample the drink himself.
47.What is the meaning of the lines of verse (诗句) quoted in the passage?
A. Men who pretend to be virtuous are actually vicious.
B. Moderate amounts of virtuousness and viciousness are present in all men.
C. Virtuous men cannot also be vicious.
D. Whether men are virtuous or vicious depends on the difficulty of their circumstances.

Old Behrman was a painter who lived on the ground floor of the apartment building. For years, he had always been planning to paint a work of art, but had never yet begun it. He earned a little money by serving as a model to artists who could not pay for a professional model. He was a fierce, little, old man who protected the two young women in the studio apartment above him.
Sue found Behrman in his room. In one area was a blank canvas (画布) that had been waiting twenty-five years for the first line of paint. Sue told him about Johnsy and how she feared that her friend would float away like a leaf on the old ivy vine(常青藤) climbing hopelessly up the outside block wall.
Old Behrman was angered at such an idea. "Are there people in the world with the foolishness to die because leaves drop off a vine? Why do you let that silly business come in her brain?"
"She is very sick and weak," said Sue, "and the disease has left her mind full of strange ideas."
"This is not any place in which one so good as Miss Johnsy shall lie sick," yelled Behrman. "Some day I will paint a masterpiece, and we shall all go away."
Johnsy was sleeping when they went upstairs. Sue pulled the shade down to cover the window. She and Behrman went into the other room. They looked out a window fearfully at the ivy vine. Then they looked at each other without speaking. A cold rain was falling, mixed with snow.
The next morning, Sue awoke after an hour's sleep. She found Johnsy with wide-open eyes staring at the covered window. "Pull up the shade; I want to see," she ordered, quietly. Sue obeyed.
After the beating rain and fierce wind that blew through the night, there yet stood against the wall one ivy leaf. It was the last one on the vine. It was still dark green at the center. But its edges were colored with the yellow. It hung bravely from the branch about seven meters above the ground.
"It is the last one," said Johnsy. "I thought it would surely fail during the night. I heard the wind. It will fall today and I shall die at the same time."
"Dear, dear!" said Sue, leaning her worn face down toward the bed. "Think of me, if you won't think of yourself. What would I do?" But Johnsy did not answer.
The next morning, when it was light, Johnsy demanded that the window shade be raised. The ivy leaf was still there. Johnsy lay for a long time, looking at it. And then she called to Sue, who was preparing chicken soup.
"I've been a bad girl," said Johnsy. "Something has made that last leaf stay there to show me how bad I was. It is wrong to want to die. You may bring me a little soup now."
An hour later she said: "someday I hope to paint the Bay of Naples."
Later in the day, the doctor came, and Sue talked to him in the hallway. "Even chances. With good care, you'll win," said the doctor. "And now I must see another case I have in your building. Behrman, whose name is some kind of an artist, I believe, has Pneumonia (肺炎), too. He is an old, weak man and his case is severe. There is no hope for him, but he goes to the hospital today to ease his pain."
The next day, the doctor said to Sue:" She's out of danger. You won. Nutrition and care now –that's all."
Later that day, Sue came to the bed where Johnsy lay, and put one arm around her. "I have something to tell you, white mouse," she said, "Mister Behrman died of pneumonia today in the hospital. He was sick only two days. They found him the morning of the first day in his room downstairs helpless with pain. His shoes and clothing were completely wet and icy cold. They could not imagine where he had been on such a terrible night.
―And then they found a lantern, still lighted, and a ladder that had been moved from its place. And art supplies and a painting board with green and yellow colors mixed on it.
―Look out the window, dear, at the last ivy leaf on the wall. Didn't you wonder why it never moved when the wind blew? Ah, darling, it is Behrman's masterpiece – he painted it there the night that the last leaf fell."
48. We can learn from the first two paragraphs that Behrman ________.
A. was ambitious and always wanted to paint a masterpiece
B. didn’t have any works and was a failure in art
C. was protective of the two girls but mostly sensitive and fierce.
D. was a professional model waiting for his great opportunity.
49. What was in Johnsy's mind all the time when she was very sick?
A. The old ivy leaves have little to do with my getting well.
B. When the last leaf falls from the ivy vine I must go.
C. I am such a bad girl as to make everything messy.
D. Sue must feel lonely if I’m not with her.
50. One can safely assume after reading the story that _____.
A. the relationship between the two girls was based on material comfort
B. Behrman was infected with Pneumonia by Johnsy
C. Behrman showed great sympathy for the two youth
D. Johnsy knew clearly why Behrman painted the ivy leaf for her.

A. The doctor indicated that Johnsy was sure to die.
B. The doctor thought that they should let her go.
C. The doctor believed that Johnsy had every chance of recovery.
D. The doctor put her chances at fifty-fifty.

Plastic cards are growing in popularity with increased demands in the advertising and marketing industry. Plastic cards are powerful tools that help connect an individual to civilization. These cards serve as an attractive promotional method by which one can reflect the business services and help represent an individual or a company uniquely and professionally.

Loyalty cards(会员积分卡) will help you keep your customers as possible customers.

Another use of plastic cards is confirming membership in an organization. These types of cards can help connect tangible(实际的) features to organizations.

Thanks to Maria Sibylla Merian, we know the truth about these winged insects. She began collecting, studying, and drawing them when she was 13. She was one of the few naturalists of her time to actually study live insects. It was through her study of caterpillars that she discovered the truth about their life cycles. Lucy Stone If you know a woman who keeps her own surname after marriage, she is continuing a tradition started by Lucy Stone. She initially changed her name, but decided to change it back a year later. She held the belief that "a wife should no more take her husband's name than he should hers." She became the first American married woman to keep her own family name for her entire life. Both she and her husband also fought the popular idea that husbands had legal control over their wives. Nellie Bly. Famous journalist Nellie Bly, was born in 1864 in Pennsylvania. When a Pittsburgh Dispatch journalist wrote an article claiming that working women were unacceptable. Bly wrote an argument that got her a job offer from the paper, Pittsburgh Dispatch. In her most famous assignment, she spent ten days living in a mental institution to expose the conditions the patients faced. Alice Coachman Alice Coachman was the first African-American woman to win Olympic gold. She grew up in Georgia, where prejudice prevented her from joining sports teams. So she trained on her own. Finally, Coachman competed in the 1948 Games in London, where she not only won a gold medal but set a record in the high jump. 21. What’s Maria Sibylla Merian’s contribution? A. She studied and drew live insects. B. She was the first woman to study insects. C. She found out the life cycles of caterpillars. D. She discovered the truth of several winged insects. 22. What can we know about Lucy Stone according to Paragraph 2? A. She never changed her family name all her life. B. She asked her husband to take her name.

高中语文基本功—— “非常6+1” 系列训练一 训练时间：第十一周本次训练得分：所用时间： 一篇美文(22分) 你家在哪里 贾丽君 “你家在哪里?” 某一个从热热闹闹的梦中醒来的清晨，我看着身边的亲人，看着周围熟悉的一切，突然就忍不住自己问自己：“我此时所身处的地方，是我自己的家吗?” 问完这个问题的时候，忽然自己就先乐了。 我想如果此刻唤醒尚在睡梦中的爱人，告诉他刚才的想法和疑问，他肯定会嘟囔一句：“神经病又犯了，睡觉吧。”然后转过身，继续他未完的梦。 而这个从梦中醒来的清晨，这个忽然而来的问题，就那么固执地悬在那里，挥之不去。 那个出生的地方或者说居住的地方就是我们的家么?那为什么还有人天天呆在家里却闷闷不乐，郁郁寡欢呢?为什么还有人不停地吟唱“人人都说没有爱，心中没有家”呢?为什么有的人要抛妻舍子、削发出家呢?那暮鼓晨钟的青灯古庙，就是僧人真正的家吗? 不久前看过一篇文章，一个拿到某国绿卡的华人女作家写的。她不远万里风尘仆仆回到国内看望父母，而已经在都市居住多年的父亲想去看看故乡。可等他们千里迢迢赶回故乡时，却发现父亲小时候居住的三间老房子，已经被流浪到此无家可归的一家三口占据。作家和父亲只能站在曾经的自家门口，进不去屋子。父女二人很感伤地回到城市的家中时，身为人母的作者却因为惦记远在国外的女儿，又要匆匆返回大洋彼岸的那个家了。 颇有意味的是，文章的题目是《回家》。 读这篇文章的时候是一个寂静的寒冬的夜晚。女儿在她的房间做作业，爱人在办公室加班。我一个人，安安静静地呆在书房，从这篇《回家》中读出了浓浓的伤感，也把自己搞到了一种浓浓的化解不开的伤感之中。 什么是家?哪里是家?为何离家?如何离家?何处安家? 我想，会有不少人在深夜寂静处，独自沉思的时候问一问自己这个看似简单、也许是“犯傻”的问题吧? 这样一个从热热闹闹的梦中醒来的安静的清晨，我坐在自己的家中，并不安静地思考着关于家的话题。我想，当人在某一个清晨或者黄昏，安然独坐、心神归一、超然物外的时候，不就是一种到家的感觉吗?家，在明确的地理位置所示意义之外，更多的，该是一种心魂所处神思所归吧?不是有句话说，心顺处，便是天堂吗?如果说家是漂泊所向，孤单所依，那么天堂就更是众望所归了。而天堂，不在身后，也不在他乡，只在心中。仅仅就这点上说，一个完整的家的概念，就应是身心所归、心灵所依之处吧? 对于远游的孩子，慈母的怀抱就是心中的故乡；对于相爱的对方，彼此的相知相守就是灵魂的喜悦；对于坚心求道的人们，青灯古卷就是心之向往；对于笃信上帝的信徒，教堂的钟声就是心灵的安顿。家从这个意义上来说，其实本不是一个具体的地方所在，只是某时某刻在某地有了安心的感觉，就算是到家了。我们可以做应该做的，只是使这种“心安”、这种“身心合一”、这种“神魂归一”的感觉尽可能的常在，那么不论一个人身居何地，都不算是离家很远，或者干脆说就是身在家中了。
