A inanometer iis ia ibillionth iof ia imeter. iA iDNA imolecule iis i 2 inanometers iin idiameter. iProtein imolecules iare iabout i 10 inanometers iin idiameter. iA ihuman ihair iis i100,000 inanometers iin idiameter. iBut iwhat iis ia inanometer iand ihow idoes iit irelate ito itechnology? iNanotechnology iis idefined ias ithe iunderstanding iand icontrol iof imatter iat idimensions iof iroughly i 1 ito i 100 inanometers, ia iscale iat iwhich iunique iproperties iof imaterials iemerge ithat ican ibe iused ito idevelop inovel itechnologies iand iproducts. iAt ithe inanoscale, ithe iphysical, ichemical, iand ibiological iproperties iof imaterials idiffer ifrom ithe iproperties iof imatter ieither iat ismaller iscales, isuch ias iatoms, ior iat ilarger iscales ithat iwe iuse iin ieveryday ilife isuch ias imillimeters ior iinches. iNanotechnology iinvolves iimaging, imeasuring, imodeling, iand imanipulating imatter ionly ia ifew inanometers iin isize. iGold inanoparticles iare imade iof ithe isame imaterial ias iin ijewelry. iBut iwhen ilight iinteracts iwith iparticles iof igold, idifferent icolors iare ireflected. iThe idifferent icolors ican ibe iused iin isimple imedical itests ito iindicate iinfection ior idisease. iMetals isuch ias icopper ibecome iextremely irigid iat ithe inanoscale, irather ithan ibendable ias iin icopper iwires iseen iin ieveryday iuse. What iis ithe imajor idifference ibetween imatter iat ithe inanoscale iand imatter iat ilarger iscalesisuch ias imillimeters ior iinches? A. At ithe inanoscale, imetals iare ibendable, iand iat ilarger iscales ithey iare irigid. B. Matter ihas idifferent iand ispecial icharacteristics iat ithe inanoscale. C. At ithe inanoscale, imatter ihas ithe isame iproperties ias imatter iat ithe iatomic ilevel. D. There iis ino idifference. Which iclaim ifrom ithe ipassage ibest idescribes ithe ibenefits iof inanotechnology? A. Scientists ican idevelop inovel itechnologies iand iproducts. B. Nanotechnology iis idefined ias ithe iunderstanding iand icontrol iof imatter iat idimensions iof iroughly i 1 ito i 100 inanometers. C. The idifferent icolors ican ibe iused iin isimple imedical itests ito iindicate iinfection ior idisease. D. Unique iproperties iof imaterials iemerge. What iis ithe iauthor’s iprimary ipurpose iin iwriting ithis iessay? A. To iexplain ihow ito iutilize ithe inanoscale B. To ireview ithe iconversion ibetween ithe inanoscale iand inanotechnology C. To iadvocate ifor ithe iusage iof imore inanotechnology D. To idescribe inanotechnology iand iwhat iit iis Neurologists iand ibiological ipsychologists ihave iwitnessed ia isharp iincrease iin ithe iknowledge iand iunderstanding iof iparticular istructures iof ithe ibrain iover ithe ipast itwo idecades. iAs itechnology ibecomes iever imore iadvanced, iscientists iare iable ito iisolate ithe ifunctions iof ieven ismall iregions iof ithe ihuman ibrain. iOne inoteworthy idiscovery iis ithe irole iof ithe iamygdala iin ihuman ifear iand iaggression. iThe iamygdala, ia ismall, ialmond-shaped iconglomerate, iis ijust ione ipart iof ithe ilimbic isystem. iLocated iat ithe ivery icenter iof ithe ibrain, ithe ilimbic isystem iis ithe icore iof iour i'emotional ibrain;' ieach iindividual istructure iin ithe ilimbic isystem iis isomehow iconnected ito ian iaspect iof ihuman iemotion. iScientists ihave ifound ithat ielectrode istimulation iof ithe iamygdala ican ielicit
extreme iand iaggressive iacts. iPatients ior iexperimental isubjects iwho iexperience ithis iutter irage iand ifearlessness ihave ino irational ifoundation ifor itheir ireaction. iIn iother iwords, ithis iaggression iis iwholly iattributable ito ielectrode istimulation. iOn ithe iother ihand, ipatients iwith itrauma ior idamage ito ithis istructure iexhibit ia icomplete iabsence iof iaggression. iResearchers ifind ithat ino iamount iof ipoking, iprodding ior iharassment iwill ievoke ieven iremotely iaggressive iresponses ifrom ithese isubjects. The iauthor isuggests ithat ipersistent ipassivity iand iimperturbability imay ibe ia idirect iresult iof iwhich iof ithe ifollowing? A. Drug-induced istimulation iof ithe iamygdala. B. A istroke ithat iresulted iin isevere itissue idamage iin ithe ilimbic isystem C. Encephalitis ias ia iresult iof ihead itrauma D. Activation iof ia istrategically iimplanted ielectrode iin ia ipatient’s iamygdala. Which istatement iis inot ilisted ias ia idetail iwithin ithe ipassage? A. Electrode istimulation iof ithe iamygdala ican ielicit iextreme iaggressive iacts. B. Scientists iare iable ito iisolate ithe ifunctions iof ieven ismall iregions iof ithe ihuman ibrain. C. Typically, itemperamental irhesus imonkeys iwith iamygdala idamage iare icompletely iimperturbable. D. Subjects iwho iexperience ithis iutter irage iand ifearlessness ihave ino irational ifoundation ifor itheir reaction. What iis ithe imain iidea iof ithe ipassage? A. The ihuman ibrain iis ias icomplex ias iit iis imysterious. B. Patients iwith idamaged iamygdalas iare iless iaggressive ithan iindividuals iwith ihealthy iones. C. Electrode istimulation iis ia ivaluable itool ifor iresearchers iwho istudy ithe ihuman ibrain. iD. iScientists ihave ilearned ia ilot iabout ihow ithe iamygdala iaffects ihuman iemotion. The iability ito isee iat ia idistance, iin igood ilight, idoes inot idiminish ias ia iresult iof iaging ito ithe iextent ithat iother ivisual iacuities ido. iMyopia, ior inearsightedness, iis imore icommon ito iyounger ieyes, iwhile ipresbyopia, ior ifarsightedness, imore icommonly iafflicts ipeople ias ithey iage. iThe iword ipresbyopia icomes ifrom iGreek ipresbys, i"old iman," iand iopia, i"eye," iand inames ia icondition iin iwhich, ibecause ithe ilens iof ithe ieye ihardens islightly iand iloses ielasticity ias ia iperson iages, ione icannot ias ieasily ifocus isharply ion inearby iobjects. iThis icondition ileads ito ithe ifamiliar ihabit iof ilifting iup ione's iglasses iand ibringing ian iobject ior ireading imaterial iclose ito ithe iface iso ithat ithe ieyes ican imore ieasily ifocus ion iit. iThe ifunction iof ithe ilens iis ito iaccommodate idifferent ifocal ipoints iso ithat isensory idata ican ibe icorrectly idirected ito ithe iretina ifor iinterpretation iinto iimages ibyithe ibrain. iCorrective ilenses, iparticularly ibifocals ior iprogressive ilenses, iadjust ifor ithe ifocal ipoint iaberration. iIn iessence, ithey ido ithe iwork ithat ithe ieye ican ino ilonger ido ifor iitself.
The imain iidea iof ithis ipassage iis ibest iexplained iin iwhich isentence?
A. Sentence i(1): iToday, ibicycles iare iso icommon ithat iit’s ihard ito ibelieve ithey ihaven’t ialways ibeen iaround. B. Sentence i(13): iIt iwasn’t iuntil i 1874 ithat ithe ifirst itruly imodern ibicycle iappeared ion ithe iscene. C. Sentence i(4): iSince ithen, ihowever, inumerous iinnovations iand iimprovements iin idesign ihave imade ithe ibicycle ione iof ithe imost ipopular imeans iof irecreation iand itransportation iaround ithe iworld. D. Sentence i(18): iToday ithey iare ibuilt, iused, iand ienjoyed iall iover ithe iworld. Which iof ithe ifollowing iwould ibe ithe ibest ititle ifor ithis ipassage? A. Bicycles iare ibetter B. A iride ithrough ithe ihistory iof ibicycles C. Cycle iyour iway ito ifitness D. The ipopularity iof ibicycles Sentence i(8); iIt ididn’t ilook imuch ilike ia imodern ibicycle, ithrough ibecause iits iback iwheeliwas isubstantially ilarger ithan iits ifront iwheel, i“follows iwhich ipattern? A. Fact, ifact B. Fact, iopinion C. Opinion, ifact D. Opinion, iopinion Macmillan iadded iiron irims ito ithe itires iof ihis ibicycle ito…. o Add iwight ito ithe ibicycle o Makes ithe itires ilast ilonger o Makes ithe iride iless ibumpy o Makes ithe iride iless itiring Cystic ifibrosis iis ia idisease ithat iis ipassed idown ithrough ifamilies. iIt iis icaused iby ia idefective igene ithat imakes ithe ibody iproduce iabnormally ithick iand isticky ifluid, icalled imucus. iThis imucus ibuilds iup iin ithe ibreathing ipassages iof ithe ilungs iand iin ithe ipancreas. iThe ibuildup iof imucus iresults iin ilife-threatening ilung iinfections iand iserious idigestion iproblems. iThe idisease imay ialso iaffect ithe isweat iglands iand ia iman's ireproductive isystem. iMillions iof iAmericans icarry ia iCF igene, ibut ido inot ihave isymptoms. iThis iis ibecause ia iperson iwith iCF imust iinherit itwo idefective igenes, ione ifromieach iparent. iAbout i 1 iin i 29 iCaucasian iAmericans ihave ithe iCF igene. iIt iis imore icommon iamong ithose iof inorthern ior icentral iEuropean idescent. iMost ichildren iwith iCF iare idiagnosed iby iage i2. For ia ismall inumber, ithe idisease iis inot idetected iuntil iage i 18 ior iolder. iThese ichildren ioften ihave ia imilder iform iof ithe idisease.
Although imost ipeople ithought ia ibridge iwas inecessary ito iexpedite itravel, isome iresidents iof ithe iBay iarea ifelt ithe irisk iof ibuilding ithe ibridge iwas itoo igreat. iJoseph iStrauss ibelieved ithat inothing iwas iimpossible, iand idreams iwould inever icome ito ifruition iif irisks iweren’t itaken. iSo, ihe idecided ito igather ithe ibest iand ibrightest ibuilders, iarchitects, iand iworkers ito iembark ion ithe ichallenge iof ibuilding ia ibridge iacross ithe iGolden iGate iStrait. iWith isafety inets iin iplace, ithe iconstruction ibegan iin i1937. iBuilding ithe ianchorages ifirst, ithe ibuilders ithen imove ion ito ithe itowers ion ieach iend, iand ithen ito ithe ithree-foot ithick icables ito isupport ithe isuspension ibridge. iLastly, iworkers ilabored ito icomplete ithe iroadway iwhich ibecome ithe imost idangerous iand itreacherous ipart iof ithe ientire itask. iThe ibuilders ihad ito ikeep ithe ibridge ibalance, iso iit iwouldn’t ifall iinto ithe ibay. iToday, iover isixty- ifive iyears ilater, ithe ibridge iremains ia ilifeline ifor ithe ipeople iof ithe iSan iFrancisco iBay iArea. The iauthors’ireason ifor iwriting ithis ipiece iseems ito ibe ito Inform ithe ireader What ibody iof iwater idoes iThe iGolden iGate iBridge icross? Golden iGate iStrait Why iwas ithe iroadway iso idangerous ito ibuild? If ithe iroad iwasn’t ibalanced, iit iwould icollapse In ithe ipassage ithe iword iembark imeans ito Begin ian iundertaking, istart Which ipart iof ithe ibridge iwas ibuilt ifirst? Anchorage Where iis iThe iGolden iGate iBridge ilocated ispecifically? A. i i iWest iCoast iB. i San iFrancisco C. i San iFernando D. iAmerica Why idid iStrauss iset ia inet? A. For isuspension B.

A iroadway The iMoon ihas ibeen iworshipped iby iprimitive ipeoples iand ihas iinspired ihumans ito icreate ieverything ifrom ilunar icalendars ito ilove isonnets, ibut iwhat ido iwe ireally iknow iabout iit? iThe imost iaccepted itheory iabout ithe iorigin iof ithe iMoon iis ithat iit iwas iformed iof ithe idebris ifrom ia imassive icollision iwith ithe iyoung iEarth iabout i4.6 ibillion iyears iago. iA ihuge ibody, iperhaps ithe isize iof iMars, istruck ithe iEarth, ithrowing iout ian iimmense iamount iof idebris ithat icoalesced iand icooled iin iorbit iaround ithe iEarth. The idevelopment iof iEarth iis iinextricably ilinked ito ithe imoon; ithe iMoon’s igravitational iinfluence iupon ithe iEarth iis ithe iprimary icause iof iocean itides. iIn ifact, ithe iMoon ihas imore ithan itwice ithe ieffect iupon ithe itides ithan idoes ithe iSun. iThe iMoon imakes ione irotation iand icompletes ia irevolution iaround ithe iEarth ievery i 27 idays, i 7 ihours, iand i 43 iminutes. iThis isynchronous irotation iisicaused iby ian iuneven idistribution iof imass iin ithe iMoon i(essentially, iit iis iheavier ion ione iside ithan ithe iother) iand ihas iallowed ithe iEarth’s igravity ito ikeep ione iside iof ithe iMoon ipermanently ifacing iEarth. iIt iis ian iaverage idistance ifrom iEarth iof i384,403 ikm. The iMoon ihas ino iatmosphere; iwithout ian iatmosphere, ithe iMoon ihas inothing ito iprotect iit ifrom imeteorite iimpacts, iand ithus ithe isurface iof ithe iMoon iis icovered iwith iimpact icraters, iboth ilarge iand ismall. iThe iMoon ialso ihas ino iactive itectonic ior ivolcanic iactivity, iso ithe ierosive ieffects iof iatmospheric iweathering, itectonic ishifts, iand ivolcanic iupheavals ithat itend ito ierase iand ireform ithe iEarth’s isurface ifeatures iare inot iat iwork ion ithe iMoon. iIn ifact, ieven itiny isurface ifeatures isuch ias ithe ifootprint ileft iby ian iastronaut iin ithe ilunar isoil iare ilikely ito ilast ifor imillions iof iyears, iunless iobliterated iby ia ichance imeteorite istrike. iThe isurface igravity iof ithe iMoon iis iabout ione-sixth ithat iof ithe iEarth’s. iTherefore, ia iman iweighing i 82 ikilograms ion iEarth iwould ionly iweigh i 14 ikilograms ion ithe iMoon. The igeographical ifeatures iof ithe iEarth imost ilike ithat iof ithe iMoon iare, iin ifact, iplaces isuch ias ithe iHawaiian ivolcanic icraters iand ithe ihuge imeteor icrater iin iArizona. iThe iclimate iof ithe iMoon iis ivery iunlike ieither iHawaii ior iArizona, ihowever; iin ifact ithe itemperature ion ithe iMoon iranges ibetween i 123 idegrees iC. ito i– 233 idegrees iC.
