A girl in gray sat upon a bench in the park, reading a book. She had come there at the same hour on the day previous, and on the day before that; and there was one who knew it.

The young man who knew it hovered near. His devotion was rewarded, for, in turning a page, her book slipped from her fingers. The young man ran upon it immediately, returning it to its owner.

The girl looked him over leisurely at his ordinary, neat dress. “You may sit down, if you like，” she said, in a deliberate contralto(女低音)．

“Do you know，” he said, “that you are the most charming girl I have ever seen? I had my eye on you yesterday. Didn’t know somebody was obsessed by those pretty lamps of yours, did you, honeysuckle？”

“Whoever you are，” said the girl, in icy tones, “you must remember that I am a lady. I will

excuse the remark you have just made because the mistake was, doubtless, not an unnatural one—in your circle.”

“I seriously beg your pardon，” said the young man. His expression of satisfaction had changed to regret and shame.

“Abandon the subject, if you please. Now, tell me about these people passing and crowding. Where are they going? Why do they so hurry？Are they happy？”

The young man had promptly abandoned his air of coquetry(嬉皮笑脸). “It is interesting to watch them，” he replied, “It is the wonderful drama of life. One wonders what their histories are.”

“I do not，” said the girl, “I am not so curious about others’ stories. I come here to sit because here, only, I can be near the great, common, beating heart of humanity. Can you guess why I spoke to you？”

The girl, held up a slender finger, and smiled slightly. “Because I wanted to talk, for once, with a natural man—one unspoiled by the dirty gloss of wealth. Oh! You do not know how tired I am of it—money, money, money! I am sick of jewels, of travel, of society, of luxuries，of all kinds. Sometimes the very tinkle of the ice in my champagne glass nearly drives me mad.”

“I have always liked to read and hear about the ways of wealthy and fashionable folks. Now, I had formed the opinion that champagne is cooled in the bottle and not by placing ice in the glass，” The young man said.

The girl gave a musical laugh of genuine amusement. “You should know，” she explained, “that just now it is a fad to put ice in champagne. The idea was originated by a visiting Prince of Tartary while dining at the Waldorf.”

“I see，” admitted the young man, humbly.

“Sometimes，” continued the girl, “I have thought that if I ever should love a man, it would be one of lowly station. One who is a worker and not a lazy bone. By the way, what is your occupation？”

“A very humble one. Were you serious when you said that you could love a man of lowly position？” “Indeed I was.”

“I work in a restaurant.”

The girl shrank slightly and asked, “Not as a waiter? Labor is noble, though.” “I am not a waiter. I am a cashier in that restaurant.”

The girl consulted a tiny watch upon her left wrist, and rose, hurriedly. “Why are you not at work？”

“I am on the night turn，” said the young man. “May I not hope to see you again？” “I do not know. Perhaps—but I must go quickly now. There is a dinner—and, oh! Perhaps you noticed an automobile at the upper corner of the park as you came. Pierre waits for me there. He supposes me to be shopping in the department store across the square. Goodbye.” Passing down the sidewalk, she entered a restaurant. There a redhead girl glanced pointedly at the clock, leaving the cashier’s desk. The girl in gray took her place.

The young man walked slowly back along the sidewalk and stepped into the automobile and said two

words to the driver：“Club, Henri.”

【解题导语】 本文为记叙文， 改编自欧·亨利的短篇小说《汽车等候的时候》。 小说描述了一个来自底层社会的女出纳员与一个来自上层社会的富家公子之间的故事。

C 解析：细节理解题。 由文中的“champagne is cooled in the bottle and not by placing ice in the glass” 可知， 香槟酒是整瓶冰镇， 而不是倒在杯子里放冰块冰镇。 而灰衣女孩却说香槟酒杯中叮当作响的冰块有时让她抓狂。 很明显， 女孩在撒谎， 她对上层社会生活的不熟悉也暴露无遗。 故答案选C。

7．What tone did the author adopt in developing the story? A．Humorous. C．Pitiful.

B．Ironic. D．Doubtful.

A

Next time you are blamed for bad behavior, mainly blame it on the whole apple, pear or any other uncut food that your parents packed in your lunch box. That’s because biting into anything that requires the use of the front teeth, is likely to cause rude behavior in kids! At least that’s the conclusion some researchers from Cornell University have made, after observing the behavior of 12 students at a summer camp.

The researchers began by dividing the students into two groups. On the first day, one group was given chicken on the bone. The other was provided with the same chicken cut into delicious, bite－size pieces so that the only way to eat it was with a fork. The following day, the food was exchanged, so that the first group received the small pieces and forks, while the second, enjoyed the chicken on the bone. Each day the camp counselors also gave the kids strict instructions to let them stay within a circle with a 9－foot radius.

The researcher recorded both the meal time and then asked behavioral experts to evaluate what happened. They agreed that the kids that were required to bite the food were twice as likely to show aggressive behavior and disobey the adults, as those that focused on eating their food with forks. Of course, the latter also showed some rude behavior. If that isn’t bad enough, the former group was also more likely to leave their special circle and even, stand and jump on the picnic tables!

This has made Mr. Wansink, who led the research and his team, conclude that for some reasons, kids that bite into their food are more likely to exhibit bad behavior than those forced to eat with forks. Therefore, he advises parents to cut up the food they serve to their kids to enjoy a peaceful meal!

【解题导语】 本文是一篇说明文。研究表明，孩子吃东西的方式可能会影响他们的行为举止。 1．What probably results in kids’ bad behavior? A．The way kids bite into food. B．The way food is cooked. C．The unhealthy food kids eat. D．Their attitude toward the food.

A 解析：细节理解题。根据第一段第二句“That’s because biting into anything that requires the use of the front teeth, is likely to cause rude behavior in kids！”可知，孩子表现粗鲁和吃东西的方式有关。故选A。

2．Paragraph 2 mainly shows ________． A．the result of the research B．the time on the research C．the way the research went on D．the difficulties the research faced

C 解析：段落大意题。根据第二段的内容可知，研究者做了一个实验，主要是为了研究孩子的粗鲁表现是否和吃东西的方式有关。在实验中孩子们被分成两组，然后在两天里分别用不同的方式吃东西。故本段主要写的是实验方式。故选C。

3．What can we learn about the students at the summer camp? A．They enjoyed the food there very much.

B．They exhibited different levels of rude behavior. C．They were asked to bite the food with care. D．They were likely to behave badly frequently.

B 解析：细节理解题。根据第三段第二句“They agreed that the kids that were required to bite the

food were twice as likely to show aggressive behavior and disobey the adults, as those that focused on eating their food with forks.”可知，因吃饭方式的不同，两组孩子粗鲁的行为出现的次数明显不同。故选B。

4．What does Mr. Wansink advise parents to do? A．To eat with their kids often. B．To teach their kids how to eat food.

C．To serve their kids with small pieces of food. D．To show their kids good behavior often.

C 解析：细节理解题。根据最后一段最后一句“Therefore, he advises parents to cut up the food they serve to their kids to enjoy a peaceful meal！”可知，Wansink先生建议家长把孩子吃的食物切成小块。故选C。

B

In its early history，Chicago had floods frequently，especially in the spring，making the streets so muddy that people，horses and carts got stuck.An old joke that was popular at the time went like this：A man is stuck up to his waist in a muddy Chicago street.Asked if he needs help，he replies，“No，thanks.I’ve got a good horse under me.”

The city planner decided to build an underground drainage(排水) system，but there simply wasn’t enough difference between the height of the ground level and the water level.The only two options were to lower the Chicago River or raise the city.

An engineer named Ellis Chesbrough convinced the city that it had no choice but to build the pipes above ground and then cover them with dirt.This raised the level of the city’s streets by as much as 12 feet.

This of course created a new problem：dirt practically buried the first floors of every building in Chicago.Building owners were faced with a choice：either change the first floors of their buildings into basements，and the second stories into mainfloors，or hoist(吊起) the entire buildings to meet the new street level.Small wood­frame buildings could be lifted fairly easily.But what about large，heavy structures like the Tremont Hotel, which was a six­story brick building?

That’s where George Pullman came in.He had developed some house­moving skills successfully.To lift a big structure like the Tremont Hotel，Pullman would place thousands of jackscrews(螺旋千斤顶) beneath the building’s foundation.One man was assigned to operate each section of roughly 10 jackscrews.At Pullman’s sign each man turned his jackscrews by the same amount at the same time，thereby raising the building slowly and evenly.Astonishingly，the Tremont Hotel stayed open during the entire operation，and many of its guests didn’t even notice anything was happening.Some people like to say that every problem has a solution. But in Chicago’s early history, every engineering solution seemed to create a new problem.Now that Chicago’s waste water was draining efficiently into the Chicago River，the city’s next step was to clean the polluted river.

【解题导语】 本文主要介绍了芝加哥为了应对洪水泛滥的问题而实行了一些解决方案的故事。 5．The author mentions the joke in Paragraph 1 to show________．

A．horses were fairly useful in Chicago B．Chicago’s streets were extremely muddy C．Chicago was very dangerous in the spring D．the Chicago people were particularly humorous

B 解析：推理判断题。根据第一段第一句“In its early history，Chicago had floods frequently，especially in the spring，making the streets so muddy that people，horses and carts got stuck.”可推知，作者提及这个笑话是为了表明芝加哥的街道非常泥泞，故选B。

6．The city planners were convinced by Ellis Chesbrough to________． A．get rid of the street dirt B．lower the Chicago River C．fight against heavy floods D．build the pipes above ground

D 解析：细节理解题。根据第三段第一句“An engineer named Ellis Chesbrough convinced the city that it had no choice but to build the pipes above ground and then cover them with dirt.”可知，Ellis Chesbrough 让城市规划者相信在地上建管道才能解决洪水泛滥所带来的问题，故选D。

7．What can we conclude about the moving operation of the Tremont Hotel? A．It went on smoothly as intended.

B．It interrupted the business of the hotel. C．It involved Pullman in turning ten jackscrews. D．It separated the building from its foundation.
