“Have a nice day!” may be a pleasant gesture or a meaningless expression. When my friend Maxie says “Have a nice day” with a smile, I know she sincerely cares about what happens to me. I feel loved and secure since another person cares about me and wishes me well.
“Have a nice day. Next!” This version of the expression is spoken by a salesgirl at the supermarket who is rushing me and my groceries out the door. The words come out in the same tone(腔调)with a fixed procedure. They are spoken at me, not to me. Obviously, the concern for my day and everyone else’s is the management’s attempt to increase business.
The expression is one of those behaviors that help people get along with each other. Sometimes it indicates the end of a meeting. As soon as you hear it, you know the meeting is at an end. Sometimes the expression saves us when we don’t know what to say. “Oh, you just had a tooth out? I’m terribly sorry, but have a nice day.”
The expression can be pleasant. If a stranger says “Have a nice day” to you, you may find it heart-warming because someone you don’t know has tried to be nice to you.
Although the use of the expression is an insincere, meaningless social custom at times, there is nothing wrong with the sentence except that it is a little uninteresting. The salesgirl, the waitress, the teacher, and all the countless others who speak it without thinking may not really care about my day. But in a strange and comfortable way, it’s nice to know they care enough to pretend they care when they really don’t care all that much. While the expression may not often be sincere, it is always spoken. The point is that people say it all the time when they like. How does the author understand Maxie’s words?
| A．Maxie shows her anxiety to the author. |
| B．Maxie really wishes the author a good day. |
| C．Maxie encourages the author to stay happy. |
| D．Maxie really worries about the author’s security. |
What does the underlined sentence in Paragraph 2 mean?
| A．The salesgirl is rude. |
| B．The salesgirl is bored. |
| C．The salesgirl cares about me. |
| D．The salesgirl says the words as a routine. |
By saying “Have a nice day,” a stranger may .
| A．try to be polite to you | B．express respect to you |
| C．give his blessing to you | D．share his pleasure with you |
According to the last paragraph, people say “Have a nice day” .

What is the best title of the passage?
| A．Have a Nice Day — a Social Custom |
| B．Have a Nice Day — a Pleasant Gesture |
| C．Have a Nice Day — a Heart-warming Greeting |
| D．Have a Nice Day — a Polite Ending of a Conversation |
The extraordinary Eastgate Building in Harare, Zimbabwe’s capital city, is said to be the only one in the world to use the same cooling and heating principles as the termite mound(白蚁堆).
Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building—the country’s largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size. The Eastgate’s owners saved $3.5 million on a $36 million building because an air-conditioning equipment didn’t have to be imported.
The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium(天井) open to the air. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通风口). As it rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys.
During summer’s cool nights, big fans blow air through the building seven times an hour to cool the empty floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents.
This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature changes—days as warm as 31℃commonly drop to 14℃at night. “You couldn’t do this in New York, with its hot summers and cold winters,” Pearce said.
The engineering firm of Ove Arup&Partners monitors daily temperatures. It is found that the temperature of the building has generally stayed between 23℃and 25℃, with the exception of the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night. And the air is fresh—far more so than in air-conditioned buildings, where up to 30% of the air is recycled.Why was Eastgate cheaper to be built than a conventional building?
| A．No air conditioners were fixed in. |
| B．It was designed in a smaller size. |
| C．Its heating system was less advanced. |
| D．It used rather different building materials. |
What does “it” refer to in Paragraph 3?
| A．Baseboard vent. | B．Heat in the building. |
| C．Hollow space. | D．Fresh air from outside. |
Why would a building like Eastgate Not work efficiently in New York?
| A．Its temperature changes seasonally rather than daily. |
| B．New York has less clear skies as Harare. |
| C．Its dampness affects the circulation of air. |
| D．New York covers a larger area than Harare. |
The data in the last paragraph suggests Eastgate’s temperature control system_____.
| A．allows a wide range of temperatures |
| B．can recycle up to 30% of the air |
| C．functions well for most of the year |
| D．works better in hot seasons |
My passion started decades ago as a kid on a flight to India. I was attracted by how such a large airplane was able to glide(滑翔）smoothly above the clouds. I made it a goal to become a pilot. I am now a pilot for American airlines. Though being a pilot consumes my life，it is a job worth doing.
My job is slightly different compared to that of a typical pilot. Most pilots have their routes they fly. They then familiarize（使…熟悉）themselves with the routes. However, in my case，I participate in any job where a pilot is immediately required. It is true that some days I might have a workday from nine in the morning to five in the afternoon. In fact，some days，I might even begin my work at three in the morning when I am needed to fly. Sometimes, as for the typical day，I do not have one.
Having been on the job for over two decades，I have learned some important life lessons. As I greet passengers boarding the airplane，I realize I，along with other airline pilots, have enhanced(提高)the lives of those who we are serving. In fact, there is one particular experience that I will never forget. A family was walking in from the gate, explaining that their beloved one was ill and had to be taken to a big hospital in another city immediately. It was at this point that I realized just how important my job was.
Therefore, my life as an airline pilot is definitely not for everyone. However，my job is something I enjoy thoroughly and will continue to do till I am old enough. As a pilot, I have been able to experience so many different types of situations in different places throughout the world. For anyone interested in piloting, I would recommend going for it.The author dreamed of being a pilot when _______.
| A．he was travelling in India |
| B．it was about 30 years ago. |
| C．he was flying to India as a kid |

| A．The author’s working time is not regular. |
| B．The author has his regular route he flies. |
| C．The author has to get up very early every day. |
| D．The daily working time of the author is longer. |
The author realized how important his job was because he _______.
| A．could serve everyone as he does his daily work |
| B．could make his guests’ life more convenient |
| C．could take the ill patient to hospital in short time |
| D．had been to many advanced countries in the world |
What would be the best title for this passage?
| A．My pleasure in serving people |
| B．Difference in my job as a pilot |
| C．My interest in being a pilot as a boy |
| D．My job as an American airline’s pilot |
Everyone has some opinion about history, no matter how ill-informed．Walking through a parking lot in a university in Miami, I noticed a bumper sticker （车尾贴纸） that said, “Ruin a Liberal’s （自由派） Day—Recite Historical Fact!” But Marwick thinks this sort of opinion is just fine; it is unavoidable that we all feel a sense of ownership of history.
History never stands still, as Marwick says at the beginning of The Nature of History, “The shape and content of history, too, vary according to the methods and materials available to different generations.” Marwick’s goal is to explain, in plain language, the changes in the way history is done up to the present; one method is to connect history with advances in the physical sciences. Marwick examines a number of case studies toward the end of the book. He ends the book with a refreshing collection of aphorisms （格言） about history. History truly belongs to each and every man and we all belong to history; with the proper education, history can be made more accessible to everyone.
Marwick relates how inventions and the physical sciences have driven historical changes. Dropping a ball in a vacuum will reveal the same properties （性质） each time the experiment is conducted, providing the conditions are the same. But historians obviously do not have the luxury of reproducing such conditions; historians view the past through the present which depends on invention and science.
By looking at the changing nature of history, Marwick feels the study progressing. Although Marwick suspects some people would accuse a historian of creating job security with the endless views of the past, he insists it is imperative based on the philosophy, science, and new materials of the age. History, according to Marwick, must be for everyone and not remain locked behind the walls of academia.The author mentions the bumper sticker in order to ________.
| A．show his own opinion about history |
| B．introduce the readers to Marwick |
| C．explain the freedom of understanding history |

| A．Marwick explains the changes in the way history is done up to the present. |
| B．Marwick connects history with advances in the physical sciences. |
| C．He ends the book with a refreshing collection of aphorisms about history. |
| D．The shape and content of history vary according to the methods and materials available. |
In paragraph 3, Marwick gives the example of dropping a ball in a vacuum to prove ______.
| A．the changeable nature of history |
| B．the difficulty of historical study |
| C．changeable ways of historical study |
| D．the difficulty of scientific study |

| B．argue against a historian |
| C．attract readers to study history |
| D．describe the story of a historian |
The U.S. government’s push to decrease the nation’s output of greenhouse gases by increasing the fuel efficiency of the cars Americans drive is arousing again an emotional argument Does driving a small, fuel-efficient car make you more likely to die on the road?
Engineers and statistical analysts can point to data that suggest more-efficient cars don’t necessarily put motorists at greater overall risk. But most of us care less about the “overall” risk than we do about ourselves. Driving a big Chevrolet Tahoe SUV makes many of us believe we are safer than we would be in a smaller car — even if statistical measures across a large population of vehicles and all kinds of car accidents suggest the advantage of safety isn’t quite as wide as SUV owners believe.
The Obama government has put the fuel-efficiency and safety question back on the front burner by calling for new-vehicle fuel economy to rise to an average of 35 miles per gallon （加仑） by 2020 from about 25 mpg today. That goal could move higher if the government decides to adopt California’s requirement to cut vehicle greenhouse-gas giving off, which would result in stricter mileage standards.
Those moves, and the effects of last summer’s gas-price shock, are driving auto makers to offer cars such as the Toyota Yaris, Honda Fit and Daimler AG’s Smart For Two — which get the kind of mileage today that law says should be the average in a decade. Beyond that, auto makers will launch a wide range of new compact （紧凑的） vehicles, and decrease production of large, body-on-frame SUVs.
That’s leading to new concerns about “green safety”, a term for managing the balance between reducing vehicle size for efficiency and adding safety and protection features that tend to make vehicles heavier and less efficient. Undoubtedly, further work has to be done before Americans make the choice.The U.S. government requires to improve the fuel efficiency in order to ________.
| A．push Americans to drive smaller cars |
| B．reduce the output of greenhouse gases |
| C．drive auto makers to produce fewer SUVs |
| D．cause Americans to make an argument |
According to Paragraph 2, engineers and analysts’ idea ________.
| A．fails to relieve people of their worry about safety |
| B．persuades people to purchase smaller cars instead of SUVs |
| C．is based on research and therefore persuasive enough |
| D．makes people think of their safety as well as others’ |
About the Obama government’s new moves, the auto makers are ________ and average Americans are ________.
| A．uncertain; positive | B．doubtful; uncertain |
| C．supportive; positive | D．positive; uncertain |
The best title for the text should be ________.

| B．Can Small Cars Overcome Accident Fears? |
| C．New Compact Cars Gets Popular in the U.S. |
| D．Do We Have to Follow the Government? |
On warm summer days with little or no wind, the air temperature in cities can be up to ten degrees higher than that of the surrounding countryside. This is a phenomenon commonly referred to as the “urban heat island” effect.
This phenomenon happens when pavement, buildings, and other infrastructure （基础设施） replace natural land cover. Large amounts of paved and dark colored surfaces—such as roofs, roads, and parking lots—absorb, rather than reflect, the sun’s heat, causing surface temperatures and overall ambient （周围的） air temperature to rise.Unlike soil, paved areas contribute to runoff, which means that as paved areas increase, the amount of water available for evaporation （蒸发） decreases. Moreover, urban areas have fewer trees and less natural vegetation which help to control the heat by providing shade and blocking solar radiation. The surfaces of leaves also provide water for evaporation which cools the air, further worsening the heat island effect.
In particular, during summer, more energy is required to cool the insides of building and for refrigeration, thereby creating additional heat output. This in turn leads to higher ambient air temperatures, which can also significantly increase the formation of urban smog in an area, degrading local air quality. Such a situation may directly affect public health with individuals more likely to suffer from heat exhaustion and the effects of asthma （哮喘）.The underlined part in Paragraph 2 means ________.
| A．Due to dark colored roads, urban areas are becoming hotter each year |
| B．Dark colored surfaces reflect the sun’s heat, causing air temperatures to rise |
| C．Because urban surfaces absorb heat, air and surface temperatures increase |
| D．Rising ambient air temperatures lead to urban surfaces absorbing more heat |
Which of the following is not a cause of the urban heat island effect?
| A．The lack of trees |
| B．The demand for refrigeration |
| C．The blocking of solar radiation |
| D．The construction of infrastructure. |
The underlined word “degrading” most probably means ________.
| A．ignoring | B．improving |
| C．highlighting | D．worsening |
The passage is mainly developed by ________.
| A．giving typical examples |
| B．following the time order |
| C．presenting the effect and analyzing the cause |
