tolookingforthetruth.不止一代的学童被他的勇敢和寻求真理的科学方法所打动。【句子分析】本句话为“morethanone+单数名词”作主语的句子。虽然morethanone意为“不止一个”，但它的谓语动词单复数却要从形式一致角度考虑。通常用单数。文中另两处以“morethanone+单数名词”作主语的句子分别为：...morethanonescientisthasquestionedwhatreallyhappened.(Para.4);Infact,morethanoneaccountsuggeststhatwhileNewtonwascertainlyinspiredbyafallingapple,...(Para.5)▶approachn.接近，靠近；方法，方式；通路，路径v.接近，靠近；对付，处理【词汇拓展】theapproachof...……的来临/临近anapproachto(doing)sth（做）某事的方法/方式（to是介词）adopt/takeanapproach采用一种方法theapproachestotheairport通往机场的道路approachthehouse走近房子see/hearsb/sthapproaching看到/听到某人/某物接近approachtheproblem/matter处理问题【即学即练】单句语法填空(1)Thedetectiveheardfootsteps______________(approach).(2)Thebestapproachto__________(build)upyourbodyistodoexerciseeveryday.approachingbuilding3Franklin,alongwith

【句式分析】(1)本句是主从复合句。其中thatwhileNewton...onthehead是that引导的宾语从句;该从句也是主从复合句,其中whileNewton...afallingapple是while引导的让步状语从句;thatithithimonthehead是that引导的同位语从句。(2)句中的infact是固定短语,意为“事实上”。Eg:Itclearlyshowedthatwhilelikabilitycanleadtohealthyadjustment,highstatushasjusttheoppositeeffectonus.这清楚地表明,尽管受人爱戴可以促进健康的调整,但地位高却对我们产生相反的影响。Activity2:Completethesummarywiththecorrectwordsorthecorrectformsofthewordsinthebracketaccordingtothepassage.Newresearchsuggeststhatthestory(1)________
