链接beawaketo...觉察到……beconsciousof...发觉……，察觉到……besensibleof...察觉到……，意识到……重点短语例释1．helpout帮助……(摆脱困境或危难)Ifyouhaven’tgottimetofinish，I’llhelpyouout.如果你来不及做完，我会帮你一把。Hewasobviouslyinsomekindoftrouble，butIdidn’tknowhowIcouldhelphimout.他显然遇到了麻烦，但我不知道应该怎样帮他。2．sortout分类；整理Wemustsortoutthegoodapplesfromthebad.咱们得把好苹果拣出来，同坏的分开。

【要点指南】couldhavedonesth.意为“本来能做某事(却没做)”，表示一种责备、埋怨或训斥等语气，与shouldhavedonesth.的意思差不多。另外，mighthavedonesth.“本来会做某事(却没做)”也表示同样的语气。Icouldhavelentyouthemoney.Whydidn’tyouaskme?我本来可以把钱借给你的，你为什么没有向我借呢？Youcouldhavewarnedmeshewascoming.你本应该告诉我她要来的。

拓展couldhavedone与mighthavedone也可表示推测语气，意为“可能做了某事”，could多用于否定句或疑问句中，这时与canhavedone和mayhavedone用法相同。Shecouldn’t/can’thavebeentoLondon，forsheknowsnothingaboutit.她不可能去过伦敦，因为她对伦敦一无所知。Hemight/mayhavegonetosleep，forthelightisturnedoff.他可能已睡觉了，因为灯已熄灭。2．Thewaterwasquiteshallowbutwherethereefended，therewasasharpdroptothesandyoceanfloor.水很浅，但到了珊瑚礁的尽头，就有一个陡坡，一直降到满是沙子的海底。【要点指南】

where此处引出地点状语从句。地点状语从句一般放在主句之后，但在一些谚语中或表示抽象意义的句子中，常把地点状语从句放在主句之前。此时的where大体相当于in/attheplacewhere，所以不可象引导定语从句的where那样换成in/atwhich。Pleasestaywhereyouare.请你待在原地。Youmustkeepthelittlechildwhereyoucanseehim.你要让这个小孩待在你能看得见他的地方。Don’tleavethemedicinebottlewherethechildrencangetit.不要把药瓶放在孩子们够得着的地方。Wherethereisawill，thereisaway.有志者，事竟成。Whereothersareweak，heisstrong.别人的弱点正是他的优势。突破阅读理解

怎样快速捕捉主题句(三)【方法技巧】主题句位于however，but，yet等信息词后。你要明白，作者在文章中突然使用了表示转折意义的副词或连词时，就表示作者的写作重心是在后面，而不是前面。所以，抓住这些信息词能使你快速捕捉住主题句。

【实例验证】IntheWest，havingasuccessfullifestyleoftenmeanshavingmaterialgoodssuchasalargehouse(ortwo)，alargecar(ortwo)，privateschoolingforthechildren，designerclothes，foreignholidaysinexoticlocations(winterandsummer)，allmodcons(现代化设备)．
