B．AmericanFarmsC．GrowitYourself D．Chip'sCountryLife解析：選A標題歸納題。銀行家Chip搬到鄉(xiāng)下后起先寵愛上了種植蔬菜，并且將吃不完的簇新蔬菜捐給社會，他的這種慈善行為漸漸吸引了很多志愿者，使得越來越多的人投入到這項幫助他人的農業(yè)活動中。因此A項“生產者”概括了文章主旨，適合作文章標題。Ⅱ.閱讀七選五Manydiseasesarecausedbythingsoutofourcontrol.Doctorsurgeustoeathealthyfoods,getexercise,stopsmokingandlimitouralcoholintake.1Anditisfreeandeasy—smiling!Whenwesmile,thebrainwiringgetsaltered.Thechemicalsthatarereleasedaremorepositive.Smilingisafirststepinfightingstressanditsharmfuleffectsonhumanhealth.Themaincauseofheartattacksandstrokesistheblockagesinbloodvessels(血管).2Themostcommonreasonfortheseblockagesisabuild-upoffattydepositsontheinnerwallsofthearteries(動脈).Whenwefeelstressedorunderpressure,ourbodyreleasesmanynaturalhormonesincludingadrenalineandcortisol.Whenwearestressedforalongperiod,thesestresshormonesareever-presentinourbodies.Andthat,medicalresearcherswarn,mayleadtohealthproblems.3However,theyclaimthatwhenpeoplearestressedforlongperiodsoftime,theymaynotmakethebestdecisionsaboutwhattoeat.Theymayovereat,smokeordrinktoomuchalcohol.Theymaynotgetenoughexerciseorsleep.Andallofthesecanleadtohealthproblems.Dr.Chockalingamsaysasmilemaybeonewaytohelp.Hetellshispatientstosmile20timesanhour.Tosome,thatmightseemlikealotofsmiling.Orsomemightevenfeelfoolish—smilingforseeminglynoreason.4Itisnotinvasive(開刀的)likeasurgicaloperation.Itisfreeandithasnosideeffects.Oncewesmile,wearerelaxed.Thisrelaxationdirectlylowersbloodpressure,improvessugarlevelsintheblood.5Anditjustmayprovidealittleextraprotectionforeveryone'shearthealth.A．Butasmiledoesnotinvolvedrugs.B．Butthereissomethingelsewecando.C．Expertssaywecancontrolandevenpreventthem.D．Theseblockagespreventbloodfromflowingtotheheartorthebrain.E．Andtheyarethenumberonecauseofdeatharoundtheworld.F．Ifwearesmiling,wearebreakingthatlinkbetweenstressandhealthproblems.G．Researcherssaythelinkbetweenstressandtheheartdiseaseisstillunclear.語篇解讀：本文是一篇說明文。很多疾病是由我們身體里的某些東西失去限制而引起的，我們可以通過微笑來避開這些疾病的產生；當我們微笑時，大腦會釋放有益的化學物質；微笑是對抗壓力給人們的健康帶來的有害影響的第一步。1．選B空前表述很多疾病都是由身體里的某些東西失去限制而引起的，醫(yī)生敦促我們吃健康的食物、熬煉、戒煙以及限制酒精攝入量，并結合空后一句可知，B項“但是我們可以做其他事情”符合語境，連接上下文，故選B項。2．選D空前表述血管中的堵塞物是心臟病和中風的主要緣由，空處應是說明堵塞物的害處，故D項“這些堵塞物阻擋血液流向心臟或大腦”符合語境，空前的“theblockages”與D項中的“Theseblockages”相呼應，故選D項。3．選G依據空后一句“However，theyclaim...whattoeat.”可知，G項“探討人員說壓力和心臟病之間的聯系尚不清晰”符合
