ithanareaofaround5.5millionsquarekilometres,theAmazonrainforestismorethanhalfthesizeofChina.亚马孙雨林占地约550万平方公里，是中国面积的一半以上。【句式剖析】句中的

“ismorethanhalfthesizeof”为倍数表达法。【考点提炼】倍数表达法常见的倍数表达法有以下几种：（前“倍”）(1)Ais＋倍数＋as＋形容词/副词原级＋asB(2)Ais＋倍数＋形容词/副词比较级＋thanB(3)Ais＋倍数＋the＋计量名词＋ofB(4)倍数＋what从句

cewhatitwastenyearsago.2.(教材P3)Abovethatisthemassofleaflitteronthedarkforestfloor.在那之上，大量落叶层覆盖着昏暗的雨林地面。【句式剖析】本句为完全倒装句。因作表语的介词短语

也表方位或地点Abovethat置于句子开头，整句进行了全部倒装。正常语序为：“Themassofleaflitteronthedarkforestfloorisabovethat.”。【考点提炼】完全倒装完全倒装，即将句中的谓语动词全部置于主语之前，此结

构通常只用于一般现在时和一般过去时，不用于进行或将来时。使用完全倒装的情况有：①当主语是名词时，将表示地点或方位的副词、介词短语置于句首，如here,there,up,down,in,away,off,out,intheroom,onthewal

l等（如果主语为人称代词，则不需倒装）；②such置于句首时，其后的句子要用完全倒装；③表语（分词、不定式、形容词、介词短语等）前置，句子用全部倒装。如：(1)IntothedarkapartmentwalkedDavid,whowasquitesurprisedwh

eneveryoneshoutedHappyBirthday.大卫走进了黑暗的房间，当大家喊生日快乐时，他感到很惊讶。(2)Thencametheordertotakeoff.起飞的命令到了。(3)Suchis(be)ourhomeinthefuture.这就

是我们未来的家。（此句也可看做因表语前置引起的完全倒装）(4)Sittingatthebackoftheclassroomwereseveraloldteachers.→现在分词、过去分词或不定式置于句首(5)Gonearethedaysw

henmyheartwasyoungandhappy.(6)Greatwashissurprisewhenheheardthenews.他听到这个消息时大为吃惊。√小试身手-完成句子1.有些人担心旅游业的迅
