Question

9．The Future Body Network
Are you tired of wires that spread all over your desk and make your tea pour onto your keyboard？If so，you may consider using devices（设备）that use technologies like Wi-Fi or Bluetooth．Neither of them sends information through wires．It sounds perfect，doesn't it？But this is not the end of the story．
Scientists are now trying to use the human body to do a similar job．They have come up with the idea of sending information over the small electric field on the surface of the skin．To do this，a transmitter（传送器）could be built into your pocket or a portable device like an MP3 player．This transmitter would then use your skin's electrical field to send information to a receiving device．Since this kind of transmission can only go as far as 20cm，the receiver would have to be close to some part of your body．
By using this body network，you wouldn't need a wire to link your MP3 player in your pocket to the headphones in your ears，or to send to your computer the pictures from a digital camera hanging around your neck．Moreover，you can exchange electronic cards or share music files with others by shaking hands，dancing cheek（脸颊）to cheek，or kissing each other．
Now，here comes a question．Why would anyone want to use their body as a network when Wi-Fi and Bluetooth already exist？The answer lies in the fact that with Wi-Fi or Bluetooth，it is hard to limit the signals only to your own use．In a busy place，you can never know who might steal your information．However，body networking is safer．It is hard for other people to pick up signals sent over the surface of your skin since this body network only has a limit of 20cm from your body．Thus，no one else can easily pick up and interpret your signals．
Moreover，the most important use of body networking in the future may well be communication within the body rather than just on its surface．Imagine having a number of small devices implanted under your skin and using them to control your own nervous system．In other words，imagine that you have a powerful in-body computer．What do you think of this idea？Does it sound cool，like being a character in the movie RoboCop？Or would you prefer to be just an ordinary human being？
40．What's the main idea of the passage？D
A．Technology is causing us to be lazy
B．Technology is doing harm to our body．
C．Technology is advancing too quickly
D．Technology is making our life easier．
41．Which of the following is NOT the way to exchange information over the skin？B
A．Shaking hands
B．Looking into one's eyes．
C．Kissing each other
D．Dancing cheek to cheek．
42．The body network is safer becauseC．
A．the information is only important to you
B．the information is stored inside your body
C．the information is sent out only 20cm from your body
D．the information is controlled by your nervous system
43．The movie RoboCop is most likely aboutA．
A．a man that is controlled by a computer
B．a computer that turns into a man
C．a robot that catches a thief
D．a thief that steals a robot．

Answer 1

分析 本文属于说明文阅读，作者通过这篇文章主要向我们描述了科技使我们的生活更便捷，科学家们正在致力于研究可以使我们通过皮肤来传递信息．

解答 40．D．主旨大意题．根据第一段Are you tired of wires that spread all over your desk and make your tea pour onto your keyboard？If so，you may consider using devices（设备）that use technologies like Wi-Fi or Bluetooth可知文章主要讲了科技使我们的生活更便捷；故选D．
41．B．细节理解题．根据第三段Moreover，you can exchange electronic cards or share music files with others by shaking hands，dancing cheek（脸颊）to cheek，or kissing each other可知握手，亲吻彼此，面对面跳舞都是在皮肤上交换信息的方法；故选B．
42．C．细节理解题．根据第四段However，body networking is safer．It is hard for other people to pick up signals sent over the surface of your skin since this body network only has a limit of 20cm from your body可知身体网络更安全因为个人信息只从你的身体向外发送20厘米；故选C．
43．A．推理判断题．根据最后一段In other words，imagine that you have a powerful in-body computer．What do you think of this idea？Does it sound cool，like being a character in the movie RoboCop可知电影机械战警是一个由计算机控制的男人；故选A．

点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
