A world-famous Canadian author，Margaret Atwood，has created the world’s first long-distance signing device(装置)，the LongPen.
After many tiring book-signing tours from city to city，Atwood thought there must be a better way to do them.She hired some technical experts and started her own company in 2004.Together they designed the LongPen.Here’s how it works：The author writes a personal message and signature on a computer tablet(手写板) using a special pen.On the receiving end，in another city，a robotic arm fitted with a regular pen signs the book.The author and fan can talk with each other via webcams(网络摄像机) and computer screens.
Work on the LongPen began in Atwood’s basement.At first，they had no idea it would be as hard as it turned out to be.The device went through several versions，including one that actually had smoke coming out of it.The investing finally completed，test runs were made in Ottawa，and the LongPen was officially launched at the 2006 London Book Fair.From here，Atwood conducted two transatlantic book signings of her latest book for fans in Toronto and New York City.
The LongPen produces a unique signature each time because it copies the movement of the author in real time.It has several other potential applications.It could increase credit card security and allow people to sign contracts from another province.The video exchange between signer and receiver can be recorded on DVD for proof when legal documents are used.
“It’s really fun，” said the owner of a bookstore，who was present for one of the test runs.“Obviously you can’t shake hands with the author，but there are chances for a connection that you don’t get from a regular book signing.”
The response to the invention has not been all favorable.Atwood has received criticism from authors who think she’s trying to end book tours.But she said，“It will be possible to go to places that you never got sent to before because the publishers couldn’t afford it.”

A.Bookstore owners don’t support the LongPen.
B.Critics think the LongPen is of little use.
C.Atwood doesn’t mean to end book tours.

解析 推理判断题。根据第六段最后一句“But she said，‘It will be possible to go to places that you never got sent to before because the publishers couldn’t afford it.’”可知，她发明这种签字笔可以给以前从来没有去过的地方的读者签字，而不是想结束book tours。故选C。
One of my favorite professors in college was a self-confessed(公开承认的) liar.
I guess that statement needs a bit of explanation.
The topic of Corporate Finance/Capital Markets is a very dry and boring subject matter.Dr K was memorable because of something he introduced at the beginning of his first class，“Between today and the class right before finals，I will put a lie into each of my lectures.Your job，as students，among other things，is to try and catch the Lie of the Day.”
And then began our 10-week course.
This was a brilliant way to focus our attention—by asking students to challenge his statements.Early in the quarter，the Lie of the Day was usually obvious—immediately causing raised hands to challenge it.
As the quarter went on，the Lie of the Day became more subtle(不易察觉的)，and many ended up slipping past most students unnoticed until a very alert person stopped the lecture to flag it.
Every once in a while，a lecture would end with nobody catching the lie.On those days，Dr K，looking quite pleased with himself，would say，“Ah ha!Each of you has one falsehood in your lecture notes.Discuss among yourselves what it might be，and I will tell you next Monday.”
Those lectures forced us to work in study groups so we could approach him with our theories the following week.
Brilliant...but what made Dr K’s technique genius was，during the most technically difficult lecture of the entire quarter，there was no lie.At the end of the lecture in which no lie was found，he offered the same challenge to work through the notes.On the following Monday，he heard our theories for what the falsehood might be for almost ten minutes before he finally said，“Do you remember the first lecture—how I said that every lecture has a lie?”
Tired from having our best theories shot down，we nodded.
“Well，THAT was a lie.My previous lecture was completely on the level.But I am glad you reviewed your notes carefully this weekend.Moving on...”
While my knowledge of the Economics of Capital Markets has faded in time，the lessons have stayed with me：“Experts” can be wrong and say things that sound right，so always evaluate new information and check it against things you already accept as fact.
