Sentencefocus1．...butitisarapidincreasewhen_compared_toothernaturalchanges.(P26)……但是，同自然界的其他变化相比，这种升高是迅速的。这是一个省略句，补全之后是．..butitisarapidincreasewhenitiscomparedtoothernaturalchanges。一般说来，省略现象多出现在下列五种状语从句中：(1)由when，while，as，before，after，till，until，once等引导的时间状语从句；(2)由whether，if，unless等引导的条件状语从句；(3)由though，although，evenif，whatever等引导的让步状语从句；(4)由as，than等引导的比较状语从句；(5)由as，asif，asthough等引导的方式状语从句。上述状语从句在省略时，并非任何成分都可以省略，而是遵循以下原则：[来源:学#科#网Z#X#X#K](1)当状语从句的主语与主句的主语一致时，可以省略状语从句的主语和系动词be，这时从句中可出现如下结构：①连词(as，asif，once)＋名词。如：Once(hewas)aworker，PangLongnowbecomesafamoussinger.庞龙曾经是个工人，现在成了一位著名的歌手。②连词(though，whether，when)＋形容词。如：Workhardwhen(youare)young，oryou'llregret.趁年轻要努力学习，要不然你会后悔的。③连词(whether，asif，while)＋介词短语。如：Helookedeverywhereasif(hewas)insearchofsomething.他到处看似乎在找什么东西。④连词(when，while，though)＋现在分词。如：While(hewas)holdingtalkswithPresidentHuJintao，USPresidentGeorgeW．BushthankedChinaforitsimportantroleintheSix－PartyTalks.在与胡锦涛主席会谈时，美国总统布什感谢中国在六方会谈中起的重要作用。10,⑤连词(when，if，evenif，unless，once，until，than，as)＋过去分词。如：Theexhibitionismoreinterestingthan(itwas)expected.这次展览比被预料的有趣得多。⑥连词(asif，asthough)＋不定式。如：OlympicgoldmedalisthurdlerLiuXiangopenedhislipsasif(hewere)tospeak.奥林匹克金牌获得者跨栏运动员刘翔张开嘴，好像要说什么。(2)当从句的主语是it，谓语动词中又含有系动词be时，可以把it和系动词be一起省略。此时构成连词(if，unless，when，whenever)＋形容词的结构。如：Unless(itis)necessary，you'dbetternotrefertothedictionary.如果没有必要，你最好不要查字典。2．There_is_no_doubt_thattheearthisbecomingwarmer...(P26)毫无疑问地球正在变暖……在Thereisnodoubt后常可跟that引导的同位语从句(在肯定句中，doubt后面有时可跟whether引导的从句)。Thereisnodoubtthatyouwillsucceedifyoutryyourbest.毫无疑问如果你尽最大努力你一定会成功。Thereisnodoubtthathewillcomeontime.他一定会准时来。类似常用结构：Thereisnoknowing/telling...没法知道/说……Thereisnoneed...没有必要……Thereisnoquestion...……是没有问题的。Thereisnoreason...没有理由……Thereisnopossibilitythat...……是没有可能的。Itisno/smallwonderthat...(Nowonderthat)．..难怪……Itisawonderthat...……真奇怪/真是令人惊奇。Step6
