In fact plenty of younger kids have one in their pocket. Practically everyone can make and receive calls anywhere, anytime. Still, 55 percent of Australians have a landline phone at home and only just over a quarter （29%） rely only on their smartphones according to a survey （调查）. Of those Australians who still have a landline, a third concede that it’s not really necessary and they’re keeping it as a security blanket — 19 percent say they never use it while a further 13 percent keep it in case of emergencies. I think my home falls into that category. More than half of Australian homes are still choosing to stick with their home phone. Age is naturally a factor（因素）— only 58 percent of Generation Ys still use landlines now and then, compared to 84 percent of Baby Boomers who’ve perhaps had the same home number for 50 years. Age isn’t the only factor; I’d say it’s also to do with the makeup of your household. Generation Xers with young families, like my wife and I, can still find it convenient to have a home phone rather than providing a mobile phone for every family member. That said, to be honest the only people who ever ring our home phone are our Baby Boomers parents, to the point where we play a game and guess who is calling before we pick up the phone（using Caller ID would take the fun out of it）. How attached are you to your landline? How long until they go the way of gas street lamps and morning milk deliveries?1. What does paragraph 2 mainly tell us about mobile phones?A. Their target users.            B. Their wide popularity.C. Their major functions.        D. Their complex design.2. What does the underlined word “concede” in paragraph 3 mean?A. Admit.         B. Argue.        C. Remember.     D. Remark.3. What can we say about Baby Boomers?A. They like smartphone games. B. They enjoy guessing callers’ identity.C. They keep using landline phones. D. They are attached to their family.4. What can be inferred about the landline from the last paragraph?A. It remains a family necessity.B. It will fall out of use some day.C. It may increase daily expenses.D. It is as important as the gas light一：重点词汇mobile Australian  pay for  landline press  in fact  plenty of  pocket practically   receive  according to survey  concede  necessary  security blanket   further emergency fall into  category stick with  naturally  factor generation  compare to  perhaps  makeup  household convenient rather than  provide  attach delivery target user popularity function complex  admit remark daily expense as important as  语法填空1．When almost everyone has a mobile phone, why are more than half of Australian homes still            （pay） for a landline（座机）2．           （Practical） everyone can make and receive calls anywhere, anytime. 3． I can still find          convenient to have a home phone rather than providing a mobile phone for every family member.4． Landline may increase         （day）expenses and it is as important          the gas light.长难句解析①　These days you’d be hard pressed to find anyone in Australia over the age of 15 who doesn’t own a mobile phone.

new,but a new study shows that we keep using our old devices(装置) well after they go out of style.That’s bad news for the environment—and our wallets—as these outdated devices consume much more energy than the newer ones that do the same things.To figure out how much power these devices are using,Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life—from when its minerals are mined to when we stop using the device.This method provided a readout for how home energy use has evolved since the early 1990s.Devices were grouped by generation.Desktop computers,basic mobile phones,and box-set TVs defined 1992.Digital cameras arrived on the scene in 1997.And MP3 players,smart phones,and LCD TVs entered homes in 2002,before tablets and e-readers showed up in 2007.As we accumulated more devices,however,we didn’t throw out our old ones.“The living-room television is replaced and gets planted in the kids’ room,and suddenly one day,you have a TV in every room of the house,”said one researcher.The average number of electronic devices rose from four per household in 1992 to 13 in 2007.We’re not just keeping these old devices—we continue to use them.According to the analysis of Babbitt’s team,old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions(排放) more than doubling during the 1992 to 2007 window.So what’s the solution(解决方案)?The team’s data only went up to 2007,but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function,such as a tablet for world processing and TV viewing.They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.1.What does the author think of new devices?A.They are environment-friendly.B.They are no better than the old.C.They cost more to use at home.D.They go out of style quickly.2.Why did Babbitt’s team conduct the research?A.To reduce the cost of minerals.B.To test the life cycle of a product.C.To update consumers on new technology.D.To find out electricity consumption of the devices.3.Which of the following uses the least energy?A.The box-set TV.    B.The tablet. C.The LCD TV.                   D.The desktop computer.4.What does the text suggest people do about old electronic devices?A.Stop using them.    B.Take them apart. C.Upgrade them.                   D.Recycle them.Passage BChildren can spend hours a day looking at computer screens and other digital devices.Some eye doctors say this leads to an increase in “computer vision syndrome(电脑视力综合征)”.Nathan Bonilla-Warford is an optometrist(验光师)in Tampa,Florida.He has seen an increase in problems in children.“A lot more children come into the office either because their parents have noticed that they have headaches or red or watery eyes or discomfort,or because their nearsightedness appears to be increasing and they’re worried,”he says.Dr.Bonilla-Warford says part of the problem is that children may be more likely to pay no attention to early warning signs than adults.“Even if their eyes start to feel uncomfortable or they start to get a headache,they’re less likely to tell their parents,because they don’t want to have the game or the computer or whatever taken away,”he explains.He says another part of the problem is that people blink(眨眼) less often when they use digital devices.He says,“A person who uses an electronic device blinks about one third as much as we normally do in everyday life.And that can result in the front part of the eye drying and not staying protected like normal.”Eye doctors offer suggestions like the following which is known as the 20/20/20 rule.That means every twenty minutes looking away twenty feet or more for at least twenty seconds from whatever device you’re using.Other suggestions include putting more distance between you and the device and using good lighting.Of course,another way is to spend less time looking at screens.Many experts say children should spend no more than two hours a day using digital devices—with no screen time for children under two.But not all eye doctors have noticed an increase in problems in children.Dr.David Hunter,from Boston Children’s Hospital,has not seen an increase in his practice.“While it is possible to develop fatigue looking at screens for a long period of time,there’s certainly no proof that it actually causes any damage to the eyes,”he says.1.Which of the following is TRUE according to the passage?A.Dr.Bonilla-Warford thinks using computers causes nearsightedness.B.People keep their eyes protected against drying by blinking normally.C.Children under two can watch TV for less than two hours a day.D.Dr.David Hunter says headaches cause an increase in eye problems.2.The syndrome in children is more likely serious than in adults because 　　　. A.adults are cleverer than childrenB.adults ignore taking care of childrenC.children always overlook early warning signsD.children always forget their parents’ words3.What does the underlined word “fatigue” mean?A.Interest.　　　B.Ability.      C.Tiredness.    D.Difficulty.4.What can be the best title for the passage?A.Looking at Screens:Two Hours or MoreB.How Can Children Use Their Eyes ProperlyC.Using Digital Devices:Advantages and DisadvantagesD.How Much Screen Time Is Proper for Children
