3．Every year in late April，students at Renmin University of China become the subjects of admiration and jealousy of their peers on other campuses in Beijing．Why？（36）F It has been a unique tradition of Renmin University for a decade．
Having fun is just one dimension of the spring break．Field trips，voluntary work，and social projects are all on students'to-do lists．Experts say the spring break is not just for students to enjoy a few days off，but for them to gain new experiences beyond the campus walls．
Push them out
The traditional Chinese belief of the exploration of knowledge and truth emphasizes"reading 10，000 books and travelling 10，000 miles"．（37）E But while Chinese universities have the tradition of spring outings，what's the benefit of making spring break an institution？
Qin Jianguo，from Shenzhen University，thinks the idea of the spring break in some universities in China comes from the intention of pushing students out of the ivory tower to experience more diversity in their lives．He said，"Take traveling for example．A week traveling is a very different experience to a one-or two-day outing．When put out in an unfamiliar context，students are expected to acquire the spirit of teamwork and compromise．（38）D"
Diverse approaches
Many countries have similar vacations in the middle of the semester for students to do things out of their own interest．Taking Japan as an example，instead of partying like their US counterparts，many Japanese students choose to work as interns or engage in study-related projects．
（39）C Pan Yingzhao，22，majoring in finance at Renmin University of China，participated in a social project on the theme of"The Chinese Dream"．She and her teammates interviewed people on the street to see how they understood"The Chinese Dream"．"Through this activity，I learned how to communicate with strangers appropriately，"Pan said．
（40）B
Apart from Renmin University，only a few other universities，have a spring break for their students．The concept in China is still far from the culture and norms built around it in the US．
Wei Xiang，a professor specializing in holiday economics at Beijing International Studies University，said that the spring break is a good experiment for universities to make study schedules smoother in order to give students more options to arrange their own leisure and study activities．

A．Not a legend
B．Not a trend yet
C．As for Chinese students，many tend to do volunteer work
D．They have to learn survival and communication skills as well
E．It does indicate the importance of experience as much as theory
F．Because they get a week off in the middle of term，the so-called spring break
G．To sum up，a spring break helps students expand their horizons and improve ability．

2．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 （白蟻堆）．
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 3.5millionona36 million building because an air-conditioning plant 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 （通風口）．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 swings-days as warm as 31℃commonly drop to 14℃at night．"You couldn't do this in New York，with its fantastically hot summers and fantastically 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．
47．Why was Eastgate cheaper to be built than a conventional building？B
A．It was designed in a smaller size．
B．No air conditioners were fixed in．
C．Its heating system was less advanced．
D．It used rather different building materials．
48．What does the underlined"it"in Paragraph 3 refer to？A
A．Fresh air from outside．B．Heat in the building．
C．Hollow space．D．Baseboard vent．
49．Why wouldn't a building like Eastgate work efficiently in New York？D
A．New York has less clear skies as Harare．
B．Its dampness affects the circulation of air．
C．New York covers a larger area than Harare．
D．Its temperature changes seasonally rather than daily．
50．The data in the last paragraph suggests Eastgate's temperature control systemB
A．allows a wide range of temperatures
B．functions well for most of the year
C．can recycle up to 30% of the air
D．works better in hot seasons．

14．Do we really know our best friends？
I like my close friends a lot，and yet，on an almost daily basis，they shocked me．I have a friend who thinks voting is a waste of time； I have another friend who never takes any arrangement to meet at a given time and place seriously．
It's generally held that friends are people with whom we choose to develop relationships because we find their personalities agreeable，or similar to our own，and yet experience regularly contradicts this．What is a friend，really？All that one can safely say is that a friend is someone one likes and wishes to see again．
The truth is that we don't know our friends．Numerous studies show that we tend to assume our friends agree with us more than they really do．The striking part is that the problem doesn't appear to lessen as a friendship deepens．When the researchers Michael Gill and Bill Swann questioned students sharing rooms，they found that，as time passed，people became even more confident in the accuracy of their judgments about the other，and yet，in reality，the judgments grew no more accurate．Two people might become dear friends，yet remain ignorant about vast areas of each other's inner lives．
This seems strange，until you consider，that many of the benefits that friendship provides don't necessarily depend on perfect familiarity； they come from something closer to reliability．Friendship may be less about being drawn to someone's personality than about finding someone willing to keep you company，or lend an ear．A friend provides the"social-identity support"we desire．You needn't be a close match with someone，nor deeply familiar with their mind．And once a friendship has begun，you want to like it，if only to confirm that you made the right decision．We don't want to know everything about our friends．We don't base friendships on what we learn about people； we decide what to learn about people，and what to ignore，based on having decided to be friends．
Perhaps there's something moving aboun ways tht viewing friendship as an agreement to keep each other company，ignore each other's faults and not probe （刨根問底） too deeply iat might weaken the friendship．Perhaps a true friend is someone who doesn't ask many awkward questions．

A．To provide background information．
B．To introduce the topic of the passage．
C．To stress the importance of friendship．

A．close friends usually know each other in depth
B．real friends are people you like but don't wish to see often
C．we do not necessarily share personalities with close friends
D．the longer we stay with friends，the more accurately we judge them
