I’ve always known my kids use digital communications gear (装置) a lot.But my cellphone bill

I’ve always known my kids use digital communications gear (装置) a lot.But my cellphone bill last month really grabbed my attention.My son had come up to nearly 2,000 incoming text messages，and had sent nearly as many.Of course，he was out of school for the summer and communicating more with friends from a distance.Nevertheless，he found time to hold down a summer job and complete a college course in between all that typing with his thumb.
I was even more surprised to learn that my son is normal.“Teenagers with cellphones each send and receive 2,272 text messages a month on average，” Nielsen Mobile says.
Some experts regret that all that keyboard jabber is making our kids stupid，unable to read non­verbal cues such as facial expressions，gestures，posture and other silent signals of mood and attitude.Unlike phones，text messaging doesn’t even allow transmission of tone of voice or pauses，says Mark Bauerlein，author of a book called The Dumbest Generation：How the Digital Age Stupefies Young Americans and Jeopardizes Our Future.
Beyond that，though，I’m not sure I see as much harm as critics of this trend.I’ve posted before on how I initially tried to control my kids’ texting.But over time，I have seen my son suffer no apparent ill effects，and he gains a big benefit，of easy，continuing contact with others.
I don’t think texting make kids stupid.It may make them annoying，when they try to text and talk to you at the same time.And it may make them distracted，when buzzing text messages interrupt efforts to noodle out a math problem or finish reading for school.
But I don’t see texting harming teens’ability to communicate.My son is as accustomed to nonverbal cues as any older members of our family.I have found him more engaged and easier to communicate with from a great distance，because he is constantly available via text message and responds with faithfulness and speed.

(答案→)B 解析：【小题1】　B解析　词义猜测题。文章倒数第二段最后一句指出，手机信息的响声会在他们试图去解数学题或读完阅读材料时打扰他们，所以手机信息的响声会令他们“分心”。【小题2】　A解析　主旨大意题。文章通过第一段作者讲述自己的儿子用手机发短信的事引出全文，所以全文主要讲述的是青少年通过收发短信与人沟通，所以正确答案为A项。【小题3】　C解析　细节理解题。依据文章倒数第二段第一句“我不认为发短信会使小孩变笨”和最后一段第一句“我没有发现短信会损害青少年的沟通能力”可知，作者对小孩使用手机发短信持支持态度。【小题4】　C解析　细节理解题。由文章倒数第二段第二句可知，有时候孩子讨厌边发短信边和他人说话。
