7．I have always known my kids use digital communications equipment 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 keep a summer job and complete a college course in between all that typing with 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 said．
     Some experts regret  that all  that  keyboard jabber（鍵盤閑聊） is making our  kids stupid，unable to read non-verbal 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 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，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 message 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 by means of text  message and responds with faithfulness and speed．
21．What is Mark Bauerlein's attitude to texting？D
A．It is convenient for teens to communicate with others．
B．It is likely to cause trouble in understanding each other．
C．It is convenient for teens to text and ca ll at the sam e time．
D．It will cause damage to the development of teens'intelligence．
22．What would be the best title for this passage？A
A．For Teens，Texting Instead of Talking
B．For Parents，Caring Much for Their Kids
C．Disadvantages of Texting
D．The Effect of Communication
23．What does the underlined word"distracted"in the fifth paragraph mean？B
A．Confused．
B．Absent-minded．
C．Comfortable．
D．Bad-tempered．

分析 很多專家認為發(fā)短信不利于孩子的身心發(fā)展，但是作者卻認為發(fā)短信不會讓孩子變笨，也不會影響孩子交流的能力．

解答 DAB
21．D 細節(jié)題 從第二段的句子：Unlike phones，text messaging doesn't even allow transmission of tone of voice or pauses，says Mark Bauerlein，author called The Dumbest Generation：How the Digital Age Stupefies Young Americans and Jeopardizes Our Future．可知 Mark Bauerlein 認為短信會對青少年的智力發(fā)展不利，選D
22．A 標題確定題 從文章的最后三段的內(nèi)容：可知作者認為和通話比起來，年輕人還是發(fā)短信好，選A
23．B 猜詞題 從后面的內(nèi)容：when buzzing text message interrupt efforts to noodle out a math problem or finish reading for school．可知當學(xué)生在做數(shù)學(xué)題目和閱讀的時候，短信的聲音會讓他們分神，選B．

點評 考查學(xué)生的細節(jié)理解和推理判斷能力．做細節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確選擇．在做推理判斷題時不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷

16．To forgive is a virtue（美德），but no one has ever said it is easy．When someone has deeply hurt you，it can be extremely difficult to let go of your hate．However，forgiveness is possible，and it can be surprisingly beneficial to your physical and mental health．People who forgive show less sadness，anger and stress and more hopefulness，according to a recent research．
（26）B．Try the following steps：
Calm yourself．（27）F．You can take a couple of breaths and think of something that gives you pleasure：a beautiful scene in nature，or someone you love．
