efforts,can we expect Beijing to take a new face in due course.唯有通力合作，我们才能期望北京不久又新的面貌。完全倒装(Complete Inversion)Then began a bitter war between the two countries.部分倒装(Partial Inversion)1)全部倒装通常只用于一般现在时和一般过去时。2)部分倒装是指将谓语的一部分如助动词或情态动词倒装至主语前。如果句子的谓语没有助动词或情态动词，则需要添加助动词do,does或did,并将其置于主语前。句首为否定或半否定的词语，如no,not,never,seldom,little,hardly,at no time,in no way,not until等。e.g.Nowhere will you find the answer to this question.Not until the child fell asleep did the mother leave the room.倒装有两种 以否定词开头作部分倒装，Not onlybut also,HardlyScarcelywhen,No soonerthan 等。so,neither,nor 作部分倒装，用这些词表示“也”，“也不”的句子要倒装。only 放句首要倒装。as,though 引导的让步状语从句必须将标语或状语提前（形容词，副词，分词，实义动词提前）。e.g.Try hard as he will,he never seems able to do the work satisfactorily.sothat，so谓语句首，要倒装。So

disadvantages that cars may bring to our lives are that we could spend more time in traffic jams and we would likely spend more money on operation and maintenance fees,making our schedules tighter and our pockets lighter!2)With these steps,we can change our society into one out of which comes the possibility that _句中的定语从句out of which comes the possibility是完全倒装 With these steps,we can change our society into one out of which comes the possibility that natural resources will be fully cherished.3)There is a real possibility that _,should there be a _.Should there be a 是省略if 并列部分倒装的将来时虚拟条件句。还原为：If there should be There is a real possibility that we can solve this problem completely,should there be cooperation among all parties involved.4）never,hardly,seldom,rarely,not,until,scarcely,in no case,in no way,by no means,on no account,at no tome放句首，句子要到装。By no means shall we cease to protect our

_.强调句。在作文需要分析原因时，可以用它阐述自己的看法。e.g.It is the tighter job markets,I suppose,that has given rise to the increase in the number of unemployed college students in China.大多数年轻人都认为过轻松不用努力的生活是最好，这是令人遗憾的事。It is

team won the football match.The earth runs around the sun,as is known by everyone.1)如果先行词是all,much,anything,something,nothing,everything,little，none等不定代词，关系代词一般只用that,不用 which.All the people that are present burst into tears.2)如果先行词被形容词最高级以及first,last,any,only,few,much,no,some,very等词修饰，关系代词常用that,不用which,who,whom.This is the last thing that I want to do.3)先行词如果有两个，一个指人，一个指物，则关系代词应该用that。The boy and the dog that are in the picture are very lonely.状语从句在句中作状语的从句叫状语从句，他可以修饰谓语、非谓语动词，定语、状语或整个句子。1.It will be some time before it returns to its original shape.“It will be before”表示“到为止，要花的时间”。本句中before一词引出一个时间状语从句。2.The plane flew higher and higher,till at last it disappeared from my sight.“tillwill at last=,and at last”表示“,终于”。一般来说，在till的前面，通常会有逗号将其分开。本句中till表示“直到”的意思，引导时间状语从句。3.The moment you understand this,you will only have further difficulties.the moment=as soon as the instant 也有相同的用法。e.g.The instant(that)she came back,she helped her brother with his homework.状语从句分为时间、地点、原因、让步、比较、方式、目的和结果状语从句等。原因状语从句 引导原因状语从句的连词有：because,as,since,for,now,that,seeing that,considering(that),in

continue to worsen.注意：only if 引导真实条件句，用于句首，主谓倒装。e.g.Only if a teacher has given permission,is a student allowed to enter this room.if only引导虚拟条件句或感叹句。e.g.If only he had come,he would have met you.让步状语从句引导让步状语从句的连词或词组有：although,though,even if though,as,while,whoever(no matter who),whatever,whenever,wherever,how,whertheror目的状语 So that,in order that,in case,for fear(that),lest.比较状语从句
