7．Most parents of kids under age 8don't worry about how much time they spend watching TV or using other media，from computers to smart phones to tablets PCs，according to a new survey that found a child's use of media often reflects how much time parents spend in the similar way．
¨We generally found that media use is not a source of conflict in the home"for families with young children，Ellen Wartella，a researcher from Northwestem University，told USA Today． She led a survey of 2，326parents who have children 8and younger．It found that in 80percent of families，children's media use was not a problem，with 55percent"not too"or"not at all"concerned about it． It also showed parents have more positive than negative feelings about how media consumption affects a child's learning and the development of creativity．The exception is video games，which are viewed more negatively than TV，computers or mobile devices．"Parents rated video games as more likely to have a negative effect on children's school performance，attention time，creativity，social skills，behavior and sleep than any other medium，"the researchers said in a news conference about the survey．
¨The findings exposes a generational shift （轉(zhuǎn)移） in parental attitudes about technology's role in young children's lives，"said Wartella．"Today's parents grew up with technology as a central pact of their lives，so they think about it differently than earlier generations of parents，instead of a battle with kids on one side and parents on the other，the use of media and technology has become a family affair．"
The researchers identified three media environments created by parents：media-centric （39percent of families），media-moderate （45%）and media-light （16%）． Children in media-centric families spend at least three hours more each day watching TV or using computers，video games and tablet PCs don't make parenting easier．And 88percent of parents say they are most likely to turn to toys or activities to keep their children occupied．Slightly fewer turn to books （79%） and TV（78%）．
The survey didn't look at how media affects children． That's a topic that the American Academy of Pediatrics has handled a number of times． The AAP says studies have found too much media use can lead to attention-problems，school difficulties，sleep and eating disorders and being fat． In addition，the Internet and cell phones can provide platforms for illegal and risky behaviors．¨By limiting screen time and offering educational media and non-electronic formats （格式）such as books，newspapers and board games，and watching television with their children，parents can help guide their children's media experience． Putting questionable content into context and teaching kids a700ut advertising contributes to their media literacy （素養(yǎng)），"it says．
The pediatricians'group says parents should have"screen-free zones"and TV should be turned off during dinner． At most，it recommends children and teens engage with entertainment media for no more than two hours a day and that should be high-quality content． It is important for kids to spend time on outdoor play，reading，hobbies and using their imaginations in free play．"Kids under 2should not use television and other entertainment media because their brains are developing quickly and they learn best from direct human interaction，"the group says．
An article on screen time by t．he Mayo Clinic also notes problems linked t．o over screen time，including being fat，irregular sleep，behavioral problems，weak school performance，violence and less time for active and creative play．

分析 本文是一篇科教文．文章講述了孩子使用媒體的經(jīng)歷與父母有關(guān)，而這一代伴隨著科技長大的父母并不擔(dān)心孩子沉迷這些電子設(shè)備．
解答 50．C 細(xì)節(jié)理解題．根據(jù)第二段的It also showed parents have more positive than negative feelings about how media consumption affects a child's learning and the development of creativity．The exception is video games，which are viewed more negatively than TV，computers or mobile devices．可知，視頻游戲比電視、電腦、手機(jī)更有負(fù)面的影響，故選C項．
51．C 細(xì)節(jié)理解題．根據(jù)第三段的Today's parents grew up with technology as a central pact of their lives，so they think about it differently than earlier generations of parents．可知，如今的父母就是伴隨著科技長大的，所以與以前的父母不一樣，他們并不擔(dān)心科技對孩子的影響，故選C項．
53．D 細(xì)節(jié)推理題．根據(jù)第四段的Children in media-centric families spend at least three hours more each day watching TV or using computers，video games and tablet PCs don't make parenting easier．可知，孩子用在電子設(shè)備的時間超過三小時，故選項D正確．
54．D 細(xì)節(jié)理解題．根據(jù)第四段的And 88 percent of parents say they are most likely to turn to toys or activities to keep their children occupied．可知，大多數(shù)的家長會讓孩子玩玩具或參加活動，讓孩子有事做，從而讓自己更輕松，故選D項．
55．B 細(xì)節(jié)理解題．根據(jù)倒數(shù)第二段的At most，it recommends children and teens engage with entertainment media for no more than two hours a day and that should be high-quality content．可知，研究人員建議青少年每天用于娛樂媒體的時間少于二個小時，同時，內(nèi)容應(yīng)該是高質(zhì)量的，故選B項．
點評 1、要想做好科教文英語閱讀理解題，平時要多閱讀科普知識類文章，學(xué)習(xí)科普知識，積累常見的科普詞匯，從根本上提高閱讀能力．
2、要熟悉科普類文章的結(jié)構(gòu)特點．科普類文章一般由標(biāo)題（Head line），導(dǎo)語（Introduction），背景（Back ground），主體（Main body）和結(jié)尾（End）五部分構(gòu)成．標(biāo)題是文章中心思想高度而又精辟的概括，但根據(jù)歷年的高考情況來看，這類閱讀理解材料一般不給標(biāo)題，而要同學(xué)們選擇標(biāo)題．導(dǎo)語一般位于整篇文章的首段．背景交待一個事實的起因．主體則對導(dǎo)語概括的事實進(jìn)行詳細(xì)敘述，這一部分命題往往最多，因此，閱讀時，同學(xué)們要把這部分作為重點．結(jié)尾往往也是中心思想的概括，并與導(dǎo)語相呼應(yīng)，命題者常在此要設(shè)計一道推理判斷題．
3、在進(jìn)行推理和理解時，一定要以閱讀材料所提供的科學(xué)事實為依據(jù)，同時所得出的結(jié)論還應(yīng)符合基本的常識，切勿隨主觀意識隨意猜測．
