什么是倒装句（语法学习：倒装句）
倒装句是一种特殊的句式，为了表达的需要将主语和谓语动词的位置发生了变化，增强语气，突出重点。
倒装句：分为全部倒装和部分倒装，及特殊的if引导的虚拟语气的倒装。1、全部倒装：将谓语动词提到主语前面。(1)therebe句型
thereisgoingtobeameeting.
thereisabookonthetable.
(2)here,there,now,then,in,out等副词置于句首时需要倒装，但主语是人称代词时，不倒装。
herecomesthebus.--------正常语序：：thebuscomeshere.
herehecomes.--------正常语序：:hecomeshere.
intheroomaremanybooks.--------正常语序：:manybooksareintheroom.
2、部分倒装：需要借助助动词的帮忙：将主+谓语改变为=助动词+主语+动词(1)so,neither,nor置于句首
ilikeswimming,sodoesmybrother.
(2)only在句首
onlywithourcombinedefforts,canwegetoverthedifficulties.
正常语序：：wecangetoverthedifficulties,onlywithourcombinedefforts.
onlyinthiswaycanwedotheworkwell.
正常语序：：wecandotheworkonlyinthisway.
(3)含有否定意义的词置于句首，如，hardly,no,seldom,nosooner,never,little,atnotime,innoway,等
neverhadiheardthat.
正常语序：ihadneverheardthat。
littledidiknowaboutthis.
正常语序：iknewlittleaboutthis.
(4)以so+形容词或副词开头的句子，如，
soheavyistheboxthathecannotcarryit.
正常语序：theboxissoheavythathecannotcarryit.
(5)用于某些表示祝愿的句中，如，
mayyoubehappyforever.
正常语序：youmaybehappyforever.
3用于省略if的虚拟条件句中将had,were,should提前，
wereiyou,iwouldn’tdothat.
正常语序：ifiwereyou,iwouldn’tdothat.
hadhecome,wewouldhavewon.
正常语序：ifhehadcome,wewouldhavewon.
