worlds 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 2020.Together they designed the LongPen.Heres 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 Atwoods basement(地下室).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 inventing finally completed,test runs were made in Ottawa,and the LongPen was officially launched at the 2020 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.“Its really fun,”said the owner of a bookstore,who was present for one of the test runs.“Obviously you cant shake hands with the author,but there are chances for a connection that you dont get from a regular book signing.”The response to the invention hasnt been all favorable.Atwood has received criticism from authors who think shes 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 couldnt afford it.”1.Why did Atwood decide to invent the LongPen?A.To set up her own company.B.To win herself greater popularity.C.To write her books in a new way.D.To make book signings less tiring.答案：D解析：细节理解题。从第二段第一句“Aftermanytiringbook-signingtoursfromcitytocity.”可知她发明这种笔的主要原因是想使签名变得轻松。2.How does the LongPen

know about the invention of the LongPen?A.It has been completed but not put into use.B.The basement caught fire by accident.C.Some versions failed before its test run.D.The designers were
