B．anti­scratchtechnologyC．lightweight D．lowprice解析：选A细微环节理解题。依据第一段最终的“forlessthan￡70”可知，它的价格低，解除D项；依据第三段最终一句中的“Theyalsohaveanti­scratchtechnologyandarelightweightindesign”可知，它有抗抓痕技术，还很轻巧，解除B项和C项。故选A项。7．HowcanyoumakeEyejustersservedifferentpurposes?A．Byfoldingglasses. B．Byadjustinglenses.C．Bycombiningglasses. D．Bychanginglenses.解析：选B细微环节理解题。依据第三段首句“Eyejustersallowyoutoinstantlychangethelens(镜片)strengthofyourglasseswithhiddendials,tuckedjustinsidetheframesthemselves.”可知，人们通过调整镜片的焦距来服务于不同的目的，所以选B。8．WhoneedEyejustersmostaccordingtoOwenReading?A．Peoplehavingperfectvision.B．Peoplewearingreadingglasses.C．Peoplechangingglassesconstantly.D．Peoplepreferringcomfortableglasses.解析：选C推理推断题。依据其次段其次句可知，为了完成一天之内不同的任务，许多人须要两三副眼镜。Eyejusters这种新型的眼镜正好可以弥补这个缺陷，可以通过调整镜片焦距来达到不同的目的，所以选C。Ⅱ.完形填空Itwasstillraining.Theshopassistantwasreadyto__1__.“No,pleasedon't，”Tammy__2__.“I'mlostandIhavenowheretogo.”Shehad__3__hermindtostaywhereshewasbecauseshewassurehermomwouldbebacktogether.Inthedistancesheheardavehicleengineandhopeditwashermomordadintheircar.Shewas__4__whenshesawitwasaschoolbusfilledwithkids.Hereyeswerefixedonthebus.Herbraingotbusywonderingifsheshould__5__thebusandifshedidso,thenhow__6__wouldhelpher,becauseshedidn'tknowwhereshe__7__.Suddenlyshesawahuge__8__monsterinthebus.Shewasreally__9__andbegantorun.Thentheschoolbuswaschasingafterher.“Wereyouhavingabad__10__，honey？”sheheardherdarlingmomask.“Yes,Mom，”shesaid__11__.“Iwaslostandbeingchasedbyaschoolbusandahugegreenmonster！”Hermotherlaughed__12__andhuggedTammyclosely.“Youpoordear！”shesaid.“Dreamscan__13__seemsoreal,right？”Tammy__14__herheadinagreementandsnuggled(依偎)closer.“Butyou'reinsafeandwarmhome！”Tammysighedin___15__.语篇解读：本文是一篇记叙文。Tammy迷路了，在商店避雨，这时一辆校车驶来，她正在琢磨是否要使校车停下，突然她看到校车里有一头绿色巨兽……这时妈妈叫醒了她，原来是一场梦，她松了一口气。1．A.arriveB．showC．leave D．come解析：选C依据下文中的“No,pleasedon't”和“I'mlostandIhavenowheretogo.”Tammy迷路了，无处可去可知，店员正打算离开(leave)，故C项正确。2．A.thought B．worriedC．hesitated D．laughed解析：选A依据上句可知，店员要离开；结合“No,pleasedon't”可知，该句是Tammy心里想的内容。A项意为“想”，符合语境。3．A.reliedon B．madeupC．dealtwith D．givenup解析：选B依据语境可知，她下定决心要待在原来的地方，因为她确信她妈妈会回来接她的。makeupone'smind为固定搭配，意为“下定决心”，故B项正确。A项意为“依靠，依靠”；C项意为“处理”；D项意为“放弃”。4．A.proud B．comfortableC．excited D．disappointed解析：选D依据上句和该句中的“whenshesawthatitwasaschoolbusfilledwi
