tolookingforthetruth.不止一代的學童被他的勇敢和尋求真理的科學方法所打動。【句子分析】本句話為“morethanone+單數(shù)名詞”作主語的句子。雖然morethanone意為“不止一個”，但它的謂語動詞單復數(shù)卻要從形式一致角度考慮。通常用單數(shù)。文中另兩處以“morethanone+單數(shù)名詞”作主語的句子分別為：...morethanonescientisthasquestionedwhatreallyhappened.(Para.4);Infact,morethanoneaccountsuggeststhatwhileNewtonwascertainlyinspiredbyafallingapple,...(Para.5)?approachn.接近，靠近；方法，方式；通路，路徑v.接近，靠近；對付，處理【詞匯拓展】theapproachof...……的來臨/臨近anapproachto(doing)sth（做）某事的方法/方式（to是介詞）adopt/takeanapproach采用一種方法theapproachestotheairport通往機場的道路approachthehouse走近房子see/hearsb/sthapproaching看到/聽到某人/某物接近approachtheproblem/matter處理問題【即學即練】單句語法填空(1)Thedetectiveheardfootsteps______________(approach).(2)Thebestapproachto__________(build)upyourbodyistodoexerciseeveryday.approachingbuilding3Franklin,alongwith

【句式分析】(1)本句是主從復合句。其中thatwhileNewton...onthehead是that引導的賓語從句;該從句也是主從復合句,其中whileNewton...afallingapple是while引導的讓步狀語從句;thatithithimonthehead是that引導的同位語從句。(2)句中的infact是固定短語,意為“事實上”。Eg:Itclearlyshowedthatwhilelikabilitycanleadtohealthyadjustment,highstatushasjusttheoppositeeffectonus.這清楚地表明,盡管受人愛戴可以促進健康的調整,但地位高卻對我們產生相反的影響。Activity2:Completethesummarywiththecorrectwordsorthecorrectformsofthewordsinthebracketaccordingtothepassage.Newresearchsuggeststhatthestory(1)________
