POINTINGATWORDS

Afaultthatisoftenseenwhenstudentsaretryingtoconcentrateispointingtothewordswithafinger,pencilorruler.Youngchildrenandverypoorreadersoftenpointwithafingerateachwordinturn.Slightlymorematurereaderssometimesholdapencilorrulerunderneaththelinewhichtheyarereading.Whilemarkingthelinemightbehelpfulforbeginningreaders,itiscertainlyunnecessaryfornormalreaders.Besidesslowingdownthereaderthroughthemeremechanicalmovementofpencil,ruler,orfinger,pointingatlinesorwordstendstocausethestudenttofocushisattentiononthewrongthing.Theimportantthingtoconcentrateonwhilereadingistheideathattheauthoristryingtocommunicate,andnotthelocationofthewordsonthepage.Theeyesofanychildoldenoughtolearnhowtoreadarecertainlyskillfulenoughtobeabletofollowalineofprintwithoutextrahelpfromfingersorrulers.

Anothercommonfaultthatiseasilyobservedisheadmovement.Thismostoftenoccurswhenstudentsarenervousabouttheirreadingortryinghard,asduringareadingspeedtest.Withheadmovementthestudenttriestoaimhisnoseatthewordheisreadingsothatashereadsacrossthelinehisheadturnsslightly.Whenhemakesthereturnsweeptobeginanewlinehisheadquicklyturnsbacksothathisnoseispointedattheleft-handmargin,andhecannowbegintoreadthenewlinebyslowlyturninghishead.Thebeliefthatthisheadmovementaidsreadingispurenonsense.Eyemusclesarequitecapableofshiftingtheeyesfromwordtoword,andthe)'neednohelpfromneckmuscles.

PreventingHIVistheonlywaytokeepthenumber'ofnewinfectionsthatoccureachyear—4million—fromgrowing.Andyetpreventionstrategies,alwaystheuglystepsistertotreatmentprograms,havenotreallytakenholdinthedevelopingnationswheretherateofinfectionishighest.Aneffectivevaccine,ofcourse,istheultimatepreventionweapon,butastheGates'pointedout,anHIVshotisstillalongwayoff.Inthemeantime,microbicidescouldbeonewaytoco-optARVsintothepreventionwar;thesearechemicalcompounds,usuallyintheform.ofagelorcream,thatwomencanusevaginallypriortointercoursetostopthetransmissionofHIV—it'sthesameideabehindspermicides(杀精子剂),whicharechemicalbarrierstospermenteringthevaginaandcausingpregnancy.It'sanelegantlysimpleapproach,madeevensimplerbythefactthatresearchersdidn'treallyhavetostartfromscratchtocomeupwithnewanti-HIVcompounds;theyalreadyhavethemintheARVs,whichnowinterruptthevirusfrominfectingcellsatvariouspointsinitslifecycle.
