Icansayforthefolksthatgavethemost,isthattheywerefullofsmiles.展评引导主语从句的关联词从属连词(不作成分）that无词义whether表“是否”。如果用了形式主语it，whether可换成if。如果whether在句首或后面直接跟ornot时，不能换成if。连接代词（作成分）what、who、whom、which、wh-+ever,如whoever、whomever、whatever、whichever,

whose等在从句中充当主语、宾语、表语、定语等成分连接副词（作状语）when、where、how、why在从句中作时间、地点、方式、原因状语等成分依据“缺什么补什么”原则确定正确的连词。所谓“缺什么补什么”是指从句与连词之间的关系。如果句子中缺主语，指人用who，指物用what。如缺宾语，指人用whom，指物用what。如缺时间状语用when；地点状语用where。

原因状语用why；方式状语用how。如缺定语用what或which或whose。如什么都不缺用that，Whether表“是否”。devote...to...movepeopletotearsYuandevotedallhislifetodevelopinghybridrice
