Unit4GlobalWarming：强调句Unit4Teachingperiod6TopicGlobalwarmingstylegrammarAimsTheuseofit(2)(it用法2)it在强调结构中英语表达中，要强调句子的某一成分，一般可用强调句型：Itis(was)+被强调部分+that(who)+句子其它部分被强调的部分指人时，除可用that外，还可换用who（强调宾语指人时也可用whom）。使用强调句型时，应注意以下事项：

一、判断是不是强调句型的关键。去掉强调结构中的Itis(was)…that(who)…后，剩下的词仍能组成一个完整的句子，就是强调句型。试比较：1.Itisstrangethathedidn’teyesterday.2.ItisyouandTomthatdidn’teyesterday.二、可以强调的成分1.强调主语1).ItisIwhoamtoblame.是我该受责怪。2).Itwasyourunclethat(who)cameyesterday.昨天来的是你叔叔。2.强调宾语1).ItwasanewpenthatMothergaveme.母亲给我的是一支新钢笔。2).ItwasabookthatIboughtformyson.我为儿子买的是一本书。3.强调状语（时间、地点、方式、原因等）1).ItwasintheclassroomthatIleftmyumbrella.我把雨伞就落在了教室里。2).Itisateleventhatthetrainleaves.火车是在十一点钟离开。3).ItwasjustasheorderedthatIacted.我正是照他吩咐的那样做的。4).ItwasbecausehewasintroublethatItriedmybesttohelphim.正是因为他有困难我才尽力帮助他4.强调宾补1).Itwasredthatwepaintedthegate.我们把门油漆成红的颜色。2).Itwaschairmanthattheyelectedhim.他们选他担任的是主席的职务。三、强调主语时，that或who后面的谓语动词的形式仍然取决于原句中的主语；be的变化只有is和was两种形式，如果要表示现在时将来时的其它各种形式时，就用Itis…,表达过去时的各种形式时，用Itwas….一般要与谓语动词的时态一致。如：1.ItisIwho/thatamanEnglishteacher.2.Itistheboywho/thatspeaksEnglishbestintheclass.3.ItwasonSundaythathegaveGeorgethisticket.4.Itisthelittlegirlwho/thathasbrokentheglass.
