Sweeping aside the doubts that many people feel about the benefits of new third generation phones and fears over the health effects of phone masts(天线竿),a recent report clains that the long-term effects of new mobile technologies will be entirely positive so long as the public can be convinced to make use of them.Research about users of mobile phones reveals that the mobile has already moved beyond being a mere practical communications tool to become the backbone (支柱)of modern social life,from love affairs to friendship to work.One female teacher,32,told the researchers:“I love my phone.It’s my friend.” The close relationship between user and phone is most pronounced among teenagers,the report says,who regard their mobiles as an expression of their identity.This is partly because mobiles are seen as being beyond the control of parents.But the researchers suggest that another reason may be that mobiles,especially taxt messaging,are seen as a way of overcoming shyness.“Texting is often used for apologies,to excuse lateness or to communicate other things that make us uncomfortable,”the report says,The impact of phones,however,has been local rather than global,supporting existing friendships and networks,rather than opening users to a new broader community.Even the language of texting in one area can be incomprehensible to anybody from another area. Among the most important benefits of using mobile phones,the report claims,will be a vastly improved mobile infrastructure(基础设施),providing gains throughout the economy,and the provision of a more sophisticated location-based services for users.The report calls on govemment to put more effort into the delivery of services by bobile phone,with suggestions including public transport and traffic information and doctors’ text messages to remind patients of appointments.“I love that idea,”one user said in an interview.“It would mean I wouldn’t have to write a hundred messages to myself.” There are many other possibilities.At a recent trade fair in Sweden,a mobile navigation product was launched.When the user enters a destination,a route is automatically downloaded to their mobile and presented by voice,pictures and maps as they drive.In future,these devices will also be able to plan around congestion(交通堵塞)and road works in real time.Third generation phones will also allow for remote monitoring of patients by doctors.In Britain scientists are developing a asthma(哮喘)management solution,using mobiles to detect early signs of an attack. 第11题：What does the writer suggest in the first paragraph about our attitudes to mobile phones？ A．We can’t live without them. B．We are worried about using them so much. C．We have contradictory feelings about them. D．We need them more than anything else to deal with modem life.

For a few excited days last week, however, it seemed as if the whole world was a cancer patient and that all humankind had been granted a reprieve(痛苦减轻) . Triggered by a front-page medical news story in the usually reserved New York Times, all anybody was talking about--- on the radio, on television, on the Internet, in phone calls to friends and relatives----was the report that a combination of two new drugs could , as the Times put it, “cure cancer in two years.” In a matter of hours patients had jammed their doctors’ phone lines begging for a chance to test the miracle cancer cure. Cancer scientists raced to the phones to make sure everyone knew about their research too, generating a new round of headlines. The time certainly seemed ripe for a breakthrough in cancer. Only last month scientists at the National Cancer Institute announced that they were halting a clinical trial of a drug called tamoxifen (他莫昔芬) ------ and offering it to patients getting the placebo(安慰剂) -----because it had proved so effective at preventing breast cancer (although it also seemed to increase the risk of uterine(子宫的) cancer). Two weeks later came the New York Times’ report that two new drugs could shrink tumors of every variety without any side effects whatsoever. It all seemed too good to be true, and of course it was. There are no miracle cancer drugs, at least not yet. At this stage all the drug manufactures can offer is some very interesting molecules, and the only cancers they have cured so far have been in mice. By the middle of last week, even the TV talk-show hosts who talked most about the news had learned what every scientist already knew : that curing a disease in lab animals is not the same as doing it in humans. “The history of cancer research has been a history of curing cancer in the mouse,” Dr. Richard Klausner, head of the National Cancer Institute, told the Los Angeles Times. “We have cured mice of cancer for decades---and it simply didn’t work in people.” 第11题：According to the passage, a person suffering from cancer will A．give up any hope. B．pray for the health of his loved ones. C．seize every chance of survival. D．go out of his way to help others.

One day I was out fishing with Spot when we heard a lot of shouting in the 38 followed by a scream and splash. I was a bit 39 so I called Spot and we both hid 40 a bush where we could see but not be 41 . After a few moments, a straw hat came drifting down the river, followed by an oar, a picnic basket and 42 oar. Then came the rowing boat itself, but it was 43 upside down ! A few seconds later my Dad and Auntie June came running 44 the river bank, both wet 45 . Spot started barking so I came out of hiding and said hello. My Dad got really angry 46 me for not trying to catch the boat as it went past. Luckily, 47 , the boat and both the oars had been caught by an overhanging tree a little further downstream, but not the hat or picnic basket. So I had to let them 48 my sandwiches. Dad and Auntie June both made me 49 not to tell Mum what had happened 50 she would be worried. 31.A.onB.byC.inD.across 32.A.whereB.thatC.whichD.when 33.A.planB.manageC.consumeD.spend 34.A.mentionB.bringC.sendD.lead 35.A.forcedB.orderedC.allowedD.encouraged 36.A.evenifB.providedC.lestD.asif 37.A.instructionB.inspectionC.protectionD.supervision 38.A.placeB.spaceC.skyD.distance 39.A.scaredB.amusedC.excitedD.disturbed 40.A.besideB.beforeC.behindD.beneath 41.A.seenB.viewedC.watchedD.observed 42.A.theotherB.eachotherC.anotherD.oneanother 43.A.rollingB.floatingC.circlingD.sinking 44.A.downB.besideC.toD.on 45.A.withinB.overC.underD.through 46.A.atB.againstC.withD.to 47.A.moreoverB.thenC.thereforeD.however 48.A.spareB.shareC.borrowD.divide 49.A.agreeB.decideC.guaranteeD.promise 50.A.exceptB.incaseC.inorderthatD.onconditionthat
