句型剖析1.【教材原文】However,whatconcernedhimmostwasthatfarmersoftenhadpoorharvestsandsometimesevenhadaseriousshortageoffoodtoeat.(page50)然而,他最關(guān)心的是農(nóng)民經(jīng)常糧食歉收,有時甚至出現(xiàn)嚴重的食物短缺。句法分析句中whatconcernedhimmost為主語從句,what在從句中做主語;that引導(dǎo)表語從句,that僅為引導(dǎo)詞,在從句中不做成分,也沒有任何意義。that和what都可以引導(dǎo)名詞性從句。that引導(dǎo)名詞性從句只起連接作用,在從句中不做任何成分,無意義,在賓語從句中通常省略,但在主語從句、表語從句和同位語從句中均不能省略;what除引導(dǎo)從句外,what本身在從句中可做主語、賓語或表語,意為“……的(東西)”,在含義上相當于“名詞+that”。語境領(lǐng)悟(1)Whatsurprisedmemostwasthatthethingirlshouldhavewonthreegoldmedals.最讓我驚奇的是這個瘦弱的女孩竟然獲得了三枚金牌。(2)Showmewhatyouhavebought.把你買的東西給我看看。(3)Mysuggestionisthatifitrainstomorrowwehadbettergotothelibrary.我的建議是,如果明天下雨,我們最好去圖書館。學(xué)以致用選詞填空(what/that)(1)Thetruthis
