　　Ⅳ.阅读理解

　　A

　　(2012·南昌模拟)

　　A 17­year­old boy, caught sending text messages in class, was recently sent to the vice principal's office.

　　The

　　vice

　　principal,

　　Steve Gallagher, told the boy he needed to focus

　　on

　　the

　　teacher,

　　not

　　his cellphone. The boy listened politely and nodded, and that's when Mr. Gallagher noticed the student's fingers moving on his lap. He was texting while being scolded for texting.“It was a_subconscious_act，” says Mr. Gallagher, who took the phone away. “Young people today are connected socially from the moment they open their eyes in the morning until they close their eyes at night. It's compulsive.”

　　A study this year by psychology students at Covenant College in Lookout Mountain, Ga. , found that the more time young people spend on Facebook, the more likely they are to have lower grades and weaker study habits. Heavy Facebook users show signs of being more sociable,

　　but they are

　　also

　　more

　　likely

　　to

　　be

　　anxious,

　　hostile

　　or depressed.

　　(Doctors,

　　meanwhile,

　　are

　　now

　　lamingaddictions to

　　‘night texting’

　　for disturbing the sleeppatterns of teens.)

　　Almost a quarter of today's teens check Facebookmore than 10 times a day, according to a 2009 survey by

　　Common Sense Media, a nonprofit group that monitors

　　media's impact on families. Will these young people get rid of

　　this habit once they enter the workforce, or will employers

　　come to see texting and ‘social­network checking’ as accepted

　　parts of the workday?

　　Think back. When today's older workers were in their

　　20s, they might have taken a break on the job to call

　　friends and make after­work plans. In those earlier eras,

　　companies

　　discouraged

　　non­business­related

　　calls,

　　and

　　someone who made personal calls all day risked being

　　fired. It was impossible to imagine the constant back­and­forth texting that defines interactions among young people

　　today.

　　Educators are also being asked by parents, students

　　and educational strategists to reconsider their rules. “In

　　past generations, students got in trouble for passing notes

　　in class. Now students are good at texting with their

　　phones

　　still

　　in

　　their

　　pockets，”

　　says

　　40­year­old

　　Mr. Gallagher, the vice principal，“and they' re able to

　　communicate with someone one floor down and three rows

　　over. Students are just fundamentally different today. They will

　　take suspensions rather than give up their phones.”

　　文章大意：现在的孩子发短信成瘾。

　　1．The underlined words “a subconscious act” in the first Paragraph refer to an act ________.

　　A．on purpose

　　B．without realization

　　C．in secret

　　D．with care

　　答案：B　猜测词义题。由上下文可知，这个孩子在挨训时，手指的抖动是下意识的动作，所以选B。

　　2．Young people addicted to the use of Facebook ________.

　　A．are good at dealing with the social relationships and concentrate on their study

　　B．have high spirits and positive attitudes towards their life and work

　　C．have been influenced mentally in the aspects of behaviors and habits

　　D．are always in a bad mood and have poor performance in every respect

　　答案：C　细节理解题。由第二段可知，使用Facebook上瘾会给人的各个方面造成影响。

　　3．Through the situation of today's older workers in their 20s, it can be inferred that ________.

　　A．the employers will not accept young people's sending text messages

　　B．a cellphone is a must for today's older workers instead of young people

　　C．the employers prefer older workers to young people

　　D．the employers will find it hard to control the interaction among young people today

　　A．like to break rules and have the same means of sending messages

　　B．are always the big problem for the education and their parents

　　C．like sending text messages but those today do it in a more secret and skillful way

　　(2011·上海春招)

　　They like using the Internet.They have lots of pocket money to spend.And they spend a higher proportion of it online than the rest of us.Teenagers are just the sort of people an online seller is interested in, and the things they want to buy—games, CDs and clothing—are easily sold on the Web.

　　But paying online is a tricky business for consumers who are too young to own credit cards.Most have to use a parent's card.They want a facility that allows them to spend money.

　　That may come sooner than they think: new ways to take pocket money into cyber(网络的)space are coming out rapidly on both sides of the Atlantic.If successful, these products can stimulate online sales.

　　In general, teenagers spend huge amounts: $153bn (billion) in the US last year and ￡20bn annually in the UK.Most teenagers have access to the Internet at home or at school—88 percent in the US, 69 percent in the UK.According to the Jupiter Research, one in eight of those with Internet access has bought something online—mainly CDs and books.

　　In most cases, parents pay for these purchases with credit cards, an arrangement that is often unsatisfactory for them and their children.Pressing parents to spend online is less productive than pressing on the high street.They are more likely to ask “Why？” if you ask to spend some money online.

　　One way to help teenagers change notes and coins into cybercash is through prepaid cards such as InternetCash in the US and Smart cards in the UK.Similar to those for pay­as­you­go mobile telephones, they are sold in amounts such as ￡20 or $50 with a concealed 14­digit number that can be used to load the cash into an online account.

　　A．More than half of the teenagers in the US and the UK have Internet access.

　　B．Teenagers pay for goods online with their own credit cards.

　　C．Most teenagers in the US and the UK have bought something online.

　　D．Teenagers found it easier to persuade parents to buy online than in a shop.

　　答案：A　正误判断题。从第四段第二句中的“Most teenagers have access to the Internet at home or at school—88 percent in the US, 69 percent in the UK.”可知，在英国和美国超过了50%的青少年可以接触到网络，故答案选A项。

　　8．A new way to help teenagers shop online is to use______.

　　A．a new machine

　　B．special coins and notes

　　C．prepaid cards

　　D．pay­as­you­go mobile phones

　　答案：C　细节理解题。从最后一段中的第一句话可知，现在一个帮助青少年网络购物的方法是用预付卡，所以答案选C。

　　9．What is the passage mainly about?

　　A．Online shopping traps.

　　B．Internet users in the US and the UK.

　　C．New credit cards for parents.

　　D．The arrival of cyber pocket money.

　　答案：D　主旨大意题。从全文可知，本文主要告诉我们如何保证青少年上网购物的安全，以及就此所采用的新方法来保障他们的网络零花钱，据此D项能较好地概括大意。
