问题 单项选择题

一张软磁盘中已存有若干信息,当什么情况下,会使这些信息受到破坏

A.放在磁盘盒内半年没有用过

B.通过机场、车站、码头的X射线监视仪

C.放在强磁场附近

D.放在摄氏零下10度的房间里

答案

参考答案:C

解析: 磁盘是以盘表闻磁介质不同的磁化方向来存放二进制信息的,所以放在强磁场中会改变这种磁化方向,也就是破坏原有信息;磁盘放置的环境有一定的要求,例如:避免日光直射、高温和强磁场,防止潮湿,不要弯折或被重物压,环境要清洁、干燥、通风。一般的x射线监视仪由于射线强度较弱,也不会破坏磁盘中原有的信息。

The slavery drama “12 Years a Slave” won the Academy Award for best picture on Sunday, making history as the first movie from a black director to win the film industry's highest honor in 86 years of the Oscars.Can anyone tell me your ideas about this movie? —— GreatMartin

“12 Years a Slave is a surprisingly underwhelming movie.It is more of a string of picture about several heartless and evil white men(and women)who are just mean without the motivation of running a plantation on their minds.There is very little character development and most of the film relies on what the audience already knows and feels about slavery.” 一一GeminiJef

‘‘Never have I been stunned into an emotional silence after watching a film in the theater.I've come out of films before thinking” My god,that was unbelievable”,like when I saw The Lord of the Rings for the first time,but this film just hits you on another level entirely.You sit there after it’s over,wondering if what you’d just experienced was real.The day after.you feel the same.”一一Pauljohnson

“This movie is just an average movie about slavery.Are you kidding me,segregation movies are a dime a dozen and this movie beat out Gravity for Golden Globes? Gravity has never been done before.12 Years a Slave I watched once and will never watch again.I watched Gravity 5 times and still love it.’’一一Dominionator

“This movie was realistic and engaging at every second.Even the dramatic pauses were worthwhile and definitely not a waste of time.The script inferred and hinted at events rather than just plain saying them,and that was genius.Outstanding photography,amazing special effects and the acting is top notch.There were a few people that walked out during some scenes.What a shame!” 一一Apols
