句型剖析1.【教材原文】However,whatconcernedhimmostwasthatfarmersoftenhadpoorharvestsandsometimesevenhadaseriousshortageoffoodtoeat.(page50)然而,他最关心的是农民经常粮食歉收,有时甚至出现严重的食物短缺。句法分析句中whatconcernedhimmost为主语从句,what在从句中做主语;that引导表语从句,that仅为引导词,在从句中不做成分,也没有任何意义。that和what都可以引导名词性从句。that引导名词性从句只起连接作用,在从句中不做任何成分,无意义,在宾语从句中通常省略,但在主语从句、表语从句和同位语从句中均不能省略;what除引导从句外,what本身在从句中可做主语、宾语或表语,意为“……的(东西)”,在含义上相当于“名词+that”。语境领悟(1)Whatsurprisedmemostwasthatthethingirlshouldhavewonthreegoldmedals.最让我惊奇的是这个瘦弱的女孩竟然获得了三枚金牌。(2)Showmewhatyouhavebought.把你买的东西给我看看。(3)Mysuggestionisthatifitrainstomorrowwehadbettergotothelibrary.我的建议是,如果明天下雨,我们最好去图书馆。学以致用选词填空(what/that)(1)Thetruthis

2.【教材原文】Today,itisestimatedthatabout60percentofdomesticriceconsumptioninChinaiscomprisedofcropsgeneratedfromYuan'shybridstrains,andhisstrainshaveallowedChina'sfarmerstoproducearound200milliontonsofriceperyear.(pages50-51)据估算,现在中国国内消费的稻米有大约60%来自袁隆平的杂交水稻品种形成的作物,这些品种让中国农民每年能够生产出大约两亿吨稻米。句法分析这个句子的真正主语是从句thatabout60percent...peryear。因为真正的主语太长,为了避免句子头重脚轻,所以用形式主语it,构成“It+be+过去分词+that”句式。英语中还有许多类似的结构,如:Itissaid/believed/reportedthat...;有时,该句型可以转换为“Sb/Sth+besaid/believed/reported+todo”或“Peoplesay/believe/report...that...”的形式。语境领悟(1)Itisestimatedthatthemeetingwilllastfourdays.这次会议预计要持续4天。(2)Thebuildingisestimatedtobecompletedintenmonths.预计大楼十个月可以完工。(3)Peopleestimatethatthedamagewasoveronemilliondollars.人们估计,损失超过了一百万美元。学以致用完成句子(1)据报道,科学家们正在努力发明治疗癌症的新药。

3.【教材原文】GiventhatYuan'shybridshavemadehimquitewealthy,onemightthinkhewouldretiretoalifeofleisure.(page51)鉴于袁隆平开发杂交水稻而变得相当富有,有人会认为他会退休享受悠闲的生活。句法分析“giventhat”在句中作连词,意思是“考虑到”,相当于consideringthat或whenyouconsider。given可用作介词,表示“只要是;考虑到;假定;已知”等意思,后面可以直接加名词,相当于considering。语境领悟(1)Givenhisage,heisverystrongandhealthy.考虑到他的年龄,他已经非常强健了。(2)Giventhatthestudentsneedmoreexercise,theheadteacherhasdecidedtoaddmorePEclasses.考虑到学生们需要更多的锻炼,校长已决定增加更多体育课。学以致用完成句子(1)我通常花钱是很明智的。考虑到自己挣得不多,我必须这样做。Usually,Iamsensiblewithmoney,asIhavetobe,
