        景清倜傥尚大节，领乡荐①，游国学。时同舍生有秘书，清求而不与。固请，约明日还书。生旦往索。曰：“吾不知何书，亦未假书于汝。”生忿，讼于祭酒。清即持所假书，往见，曰：“此清灯窗所业书。”即诵辄卷。祭酒问生，生不能诵一词。祭酒②叱生退。清出，即以书还生，曰：“吾以子珍秘太甚，特以此相戏耳。”             
【注释】①领乡荐：古代称乡试中试为领乡荐。②祭酒：国子监的主管官员。

  The Dress That Turns into a Coca Cola Machine 

    This specially designed dress looks like a normal dress，but if you unfold it and cover yourself，you may look like a Coca Cola vending machine（自动售货机）. Because there are many vending machines like that on the street，it must be easy for you to hide．If you feel that someone is following you or there is some danger，you can disappear within five seconds．But don't use it to scare your classmates．That'll be rude.
                                  

    The M-Dress is a nice black dress．It is also a mobile phone．It accepts a standard SIM card and allows the wearer to receive calls without carrying an actual(真实的) phone in their pocket or purse．You just need to bring your hand to your ear when you want to answer a phone call．When you finish talking and release your hand，the call will close．It is fashionable and useful．But it will certainly be an embarrassing moment when your dress rings in public．
  Air Conditioned Jackets 

    You will love these air-cooled jackets in summer time when it is very hot outdoors．The jacket has fans that draw air in．The fan is powered by an inside battery．Now it is possible to spend nearly every second of your day with cool air．
