上海1115大火让我们再度认识气压原理的延伸的烟囱原理．具体的说，烟囱上方的空气流动造成烟囱出口处的气压减小，而烟囱底部与周围大气压相同，即比烟囱口处的气压大些，于是即使是冷空气也会从烟囱底部周围被压入烟囱里面，再从高处的出口跑出去．这也就是我们看到的“抽”的表象了．烟囱效应造成的现象解释或应用错误的是（　　）

A．高楼一旦起火，火焰通过楼梯间、电梯井等竖向井道从一楼烧到顶楼只需要几分钟，往往很难扑救

B．从底部到顶部具有通畅的流通空间的建筑物、排风道、排烟道中，空气（包括烟气）靠密度差的作用，沿着通道很快进行扩散或排出建筑物

C．在建筑设计中，可利用热空气上升的原理，在建筑上部设排风口可将污浊的热空气从室内排出，而室外新鲜的冷空气则从建筑底部被吸入

D．对于已采暖的建筑物，尽量要使低层部分的室内温度高于高层部分

     Each term. Andrew Tom receives a term bill, tuition (学费), student center recreation fee, resident activity

fee, health insurance. If only the rest of his expenses were as easy to quantify (确定数量).

     "It' s like you start out the term With plenty of money and then $ 20 for dinner out here and $100 at the

department store there, it' s gone," said Tom, a third-year student."And there are so many daily necessary

things that you don' t think about until you get there and need it."

     From the books to the fashionable clothes, college students say~ the expenses of a college education go

well beyond tuition and a dining hail meal plan. Many say they arrive on campus only to be frightened by

unexpected costs from sports fees to the actual price of a slice of pizza.

     Balancing a job with schoolwork, especially at colleges known for their heavy workloads like Harvard and

MIT, can be tough. So can the pressure that students of- ten feel in order to financially go along with their

friends.

     "When you get dragged along shopping, you're going to spend money; if you, get dragged to a party and

everyone wants to take a taxi but you are cheap and wantto take a bus, chances are you' 11 end up sharing

the fee for the taxi," said Tom."Iguess you could say no, but no one wants to be the only one eating in the

snack bar while our friends are out to dinner."

      Max Cohen, a biology major at MIT, said he is used to watching fellow students spend $ 40 a night to

have dinner delivered or $ 50 during a night out at a bar. During the school' s recent spring break, friends on

trips for the week posted away messages that read like a world map-Paris, Rome, Tokyo."Meanwhile I

stay at home and work," said Cohen."I didn't realize when I came here how much money I would spend or

how hard I would have to work to get by."

     It is a lesson some younger students learn quickly. Others, surrounded by credit card offers, go into debt,

or worse, are forced to leave school. 

     "A lot of people don' t think twice about how much they spend," said a first year student at M1T,"and you

feel the pressure sometimes to go along with them."

“教师不在于他教了多少年书，而在于他用心教了多少年书。有一些人，他教一年，然而重复五年十年乃至一辈子；有一些人，实实在在地教了五年。一个实实在在教五年的人，与一个教了一年却重复了一辈子的人，他的成就是不一样的。”
