only+状语引导的部分倒装
英语半倒装
“全倒装”，但条件是“主语是名词”---即属于是代词就不能全倒装，
代词是主语，可以部分倒装!
Only的倒装用法：要点：主句半倒装
1，only+疑问副词（when,where,how）+从句+谓语+主语+其他
2，only+until/till+从句+谓语+主语+其他
3，only+状语+谓语+主语+其他
SO引导的倒装句:主句半倒装
1、So + 形容词 + be/V + 主词 + that + 句子
2、so +助动词+主语，这种结构表示主语也这样。
3、so +主语+助动词，表示是的，他们是。
是对前半句的再次肯定。
否定意义的词放句首，句子部分倒装：
nether=nor 都是conj.连词后加句子一定用半倒装！且用法相同
举个例子： He didn't realize his mistake until then .
改成：Not until then did he realize his mistake.
I will never forget those days.
改成：Never will I forget those days.
是指本来放在句中的否定词放到句首用部分倒装，Not all the students understand the problem. 此句表示部分否定。
not 和all 构成部分否定
not 只修饰all ，
not 只和主语all 有关，是不倒装的
否定词是原句子中修饰谓语的，这个否定词提前时句子才用半倒装
※一般是把否定词放句首，后接助动词+主语+ 动词，所以这个否定词和主语是没有关系的。

•如果on置于句首后面加的不是介词短语、副词或状语从句，此时就不用倒装。
On when he finihe a her ta doe he fee reaed
置于句首后面加的不是介词短语、副词或状语从句，此时就不用倒装。

部分倒装常见用法归纳
- 189 -校园英语 / 基础教育部分倒装常见用法归纳重庆市綦江中学/赵小淑所谓部分倒装，则是指将谓语的一部分如助动词或情态倒装至主语之前。
如果句中的谓语没有助动词或情态动词，则需添加助动词do, does 或did ，并将其置于主语之前。
然而在实际运用中，有的是主句倒装，而有的却是在从句部分倒装，甚至还有特殊情况，这无疑增加了学生理解和掌握的难度。
为了帮助学生更轻松地理解并掌握，我个人觉得可以从以下几方面去学习：一、主句部分倒装1. Only 及其状语位于句首时要部分倒装，如果状语是从句时，只要求主句部分倒装： 例：Only after he had spoken out the word did he realize he had made a big mistake.2. so /such …that …句型中，若将so+adj/adv.或者such+n.提到句首时，则将主句变成部分倒装句：例：So shallow is the river that we can see the fish clearly.Such a shy girl is she that she seldom speaks to anyone except her parents.3. 以否定或半否定意义的副词或介词短语开头的句子要求部分倒装。
常见的否定副词有: no, not, never, seldom, little, hardly, barely,little, not nearly, not only ，at no time; by no means; for no reason; in no case; in/under no circumstances; in no sense; in no way; on no account; on no consideration; at no point 等。
但是，当not until 引出主从复合句，则要求主句倒装，从句不倒装。
only的几个主要用法
在学习英语的过程中,我们常遇到only与其它词或结构搭配来表达不同的意思,现将这些用法示例一、only引导的词组或句子放在句首作状语时,通常要用倒装结构;如Only in this way can you solve the problem.只有通过这种方式你才能解决问题;Only if you study hard can you pass the exam.只有努力学习才能通过考试;Only then did I realize my mistake.只有那时我才意识到错了;二、not only...but also出现在句首时,如果架连接的是两个句子,常用倒装;如Not only did we lose all our money,but we also came close to losing our lives.我们不仅丢了钱,还差点把命丢了;Not only did he speak correctly,but he also spoke easily.他不仅说得准确,而且说得很轻松;三、only放在不定式前面,常表示不愉快或出乎人们的意料的结果;如I went all the way to his home only to find him out at a meeting.我径直到他家里去,不料发现他出去开会了;I hurried to the post office only to find it closed.我匆忙赶到邮局,不料已经关门了;She went home only to find her house burglarized.她回到家里,发现房子被盗了;四、“too...to...”结构中,表示否定意思,但在“only too...to...”结构中,only too = very,表示肯定意思;如The patient is too weak to walk.那个病人太虚弱了,走不动;We are only too willing to do it for you.我们非常愿意为你做那事;I am only too delighted to accept your king invitation.我非常高兴地接受你的邀请;五、在“one of + 复数名词+ 定语从句”的结构中,定语从句一般被看作修饰复数名词,谓语要用复数形式;但在“the only one of + 复数名词+ 定语从句”的结构中,定语从句却被看作修饰“the only one”,谓语动词要用单数形式;如This is one of the best novels that have been published in the past two years.这是近两年出版的最好的小说之一;He was the only one of the boys who was given a prize.他是这些孩子中唯一受到奖励的;She is the only one of the girls who has been to the US.她是那些女孩中唯一去过美国的;六、If only 为虚拟语气的一种,表示愿望或一个未实现的条件,多用于感叹句,其主句常常省略;如If only she would marry me她要是能和我结婚该多好If only he had known about it他那时要是知道这件事该多好If only you could have been here earlier that day要是你那天再早点到这就好了;If only there were forty-eighty hours in a day.要是一天有48个小时就好了;首先,在全部倒装的句子中,要把整个谓语放在主语的前面去而构成倒装语序;例如：There are large numbers of students in the lecture hall.在There be…的句式中,There只是个引导词而不是主语,真正的主语是后面作表语的名词或者名词短语;因此,There be…的句式都是全部倒装的句子;演讲厅里有大量的学生;When he ran to the door, there stood a mid-aged man with a lantern in his hand .此句是为了"描述情节的需要",把倒装当着修辞的手段而写成了全部倒装句;句子的主语是a mid-aged man,谓语是stood ;当他向房门跑去时,那儿正立着一位手里拿着一盏灯笼的中年男人;另外,在部分倒装的句子中,只把谓语的一部分如情态动词、助动词、或是系动词be放到主语的前面去,构成倒装语序;例如：Are you going to take part in the football match against Accounting Department on Friday afternoon 句子的谓语是are going to take part,are是句子的谓语的一部分；句子的主语是you ;所以,此句是部分倒装的句子;疑问句都是部分倒装句;你打算去参加星期五与会计系进行的足球赛吗Hardly could he finish his test paper when the school bell rang .由于语法要求的原因,本句写成了部分倒装的句子;它的自然语序应该是：When the bell rang, he could hardly finish his test paper.他还未做完试卷,下课铃就响了;了解了倒装语序的构成情况后,我们再来看看倒装语序在各种不同类句子中的使用情况：A. 在疑问句中各种疑问句一般地说都是倒装语序;例如：Will they come to see us this weekend 这个周末他们将来看我们吗Are you talking about the film you saw last Monday你们是在谈论你们上周一看的那部电影吗Can you speak another foreign language except English除开英语,你还能说另一种外语吗Where did you buy the dictionary, in the book store nearby or in Xinhua bookstore你在哪儿买的这本词典,是在附近的书店还是在新华书店She is not a student, isn‘t she 她不是个学生,对吗B. 在感叹句中某些感叹句也用倒装语序;例如：Is n‘t it a beautiful garden 多么美丽的花园啊What a beautiful garden it is 多么美丽的花园啊在这种句式中,主语在谓语之前,属于自然语序;对于主语和谓语而言,语序没有倒装;Have you ever seen such a naughty kid like him你见过那个孩子像他这么调皮C. 在陈述句中陈述句在一般情况下用自然语序；但由于英语语法的某些原因,陈述句也要使用倒装语序;这些原因大致可以归纳1 为了避免句子部分内容不必要的重复,常用"so + be动词助动词、情态动词+主语"或"neither / nor + be动词助动词、情态动词+主语"的倒装句式;其中第一个句式表示"与前面所述的肯定情况相同", 第二个句式表示"与前面所述的否定情况相同";例如：His brother is a college student; so is mine.他弟弟是大学生,我弟弟也是;His brother is not a college student; nor is min .他弟弟不是大学生,我弟弟也不是;He used to have his further study abroad; so did I.他曾去国外深造过,我也去过;He didn‘t use to have his further study abroad; neither did I.他没去国外深造过,我也没有;One of my friends can speak three foreign languages; so can his wife.我的一个朋友会说三门外国语,他的妻子也会;One of my friends cannot speak three foreign languages; neither can his wife .我的一个朋友不会说三门外国语,他的妻子也不会;They are now preparing for their final examinations; so are we .他们正在为期末考试作准备,我们也一样;They are not now preparing for their final examinations; nor are we .他们没在为期末考试作准备,我们也没有;2具有否定意义的词或短语置于句首时除否定词修饰主语外,句子一般要写成部分倒装句;这类词或短语常见的有：not, never, seldom, hardly, rarely, scarcely, by no means, under no circumstances, in no way, at no time, no sooner … than, hardly … when, not only … but also, not until… ,等;例如：Hardly had she sat down when she heard someone knocking at the door .她还没来得及坐下来,就听见有人敲门;Not until t welve o‘clock did he go to bed last night .他昨晚直到十二点钟才睡觉;Never have my sisters been to Hong Kong before .我的妹妹们以前从未去过香港;No sooner had I returned home from New Zealand than I bought a house and went to live there.我从新西兰一回国,就买了一栋房子并在那儿住下了;So far as I know seldom does Mary come back to see her mother.就我所知,玛利几乎很难回来看她妈妈;Scarcely a drop of rain fell here last fall . 否定词修饰主语时,句子不用倒装; 去年秋天,这儿几乎没下一滴雨;英语六级语法：多个形容词修饰名词的顺序多个形容词修饰名词时,其顺序为：限定词--数词--描绘词--大小,长短,形状,新旧,颜色--出处--材料性质,类别--名词a small round tablea tall gray buildinga dirty old brown shirta famous German medical schoolan expensive Japanese sports car典型例题:1 Tony is going camping with ___ boys.A.little two otherB. two little otherC.two other littleD.little other two答案：C;由"限定词--数词--描绘词--大小,长短,形状,新旧,颜色--性质--名词"的公式可知数词,描绘词,性质依次顺序,只有C符合答案;2One day they crossed the ____bridge behind the palace.A. old Chinese stoneB.

We visited some friends,and spent the ___days at the seaside.A. few last sunnyB. last few sunnyC. last sunny fewD. few sunny last答案：B;本题考查多个形容词的排序问题;一般与被修饰形容词关系密切的形容词靠近名词；如果几个形容词的重要性差不多,音节少的形容词在前,音节多的方在后,在不能确定时,可参照下表：限定词+数量词序数词在前,基数词在后+性状形容词+大小、长短、高低等形体+those + three + beautiful + large + square新旧+颜色+国籍+材料+名词old + brown + wood + table针对性句型1. 我深信……：I am greatly convinced that从句/I am greatly assured that从句例我深信预防胜于治疗;=I am greatly convinced that prevention is better than cure.2. ……是很容易证明的：It can be easily proved that从句例时间最珍贵是很容易证明的;=It can be easily proved that nothing is more precious than time;3. ……无论如何强调都不为过：...cannot be overemphasized例交通安全的重要性无论如何强调都不为过;=The importance of traffic safety cannot be overemphasized;4. 在我看来……；我认为……: In my opinion.../To my mind.../As far as I am concerned.../I am of the opinion that从句例在我看来,打电子游戏既花费时间又有损健康;=In my opinion, playing video games not only takes much time but also is harmful to health;5. 不用说……: It goes without saying that从句/Needless to say that从句/It is obvious that 从句/Obviously,主语+谓语+宾语例不用说,早睡早起是值得的;=It goes without saying that it pays to keep early hours;6. ……是不可能的；无法……: There is no+doing sth. /There is no way of+doing sth. /There is no possibility of+doing sth. /It is impossible to do sth. /It is out of the question to do sth. /No one can+do sth. /...cannot+do sth;例不可否认,事业成功的关键在于身心健康;=There is no denying that successful business lies in a healthy body and mind;7. 人人知晓……/毫无疑问……：Everyone knows that从句/There is no doubt that从句例毫无疑问,近视在我国的年青人中是一个严重的问题;=There is no doubt that near sightedness is a serious problem among the youth in our country;8. ……是必要的：It is necessary that+主语+should+谓语……是重要的：It is important/essential+that 主语+should+谓语……是适当的：It is proper that+主语+should+谓语……是紧急的：It is urgent that+主语+should+谓语例我们应当保持公共场所的清洁;=It is proper that we should keep the public places clean;p副标题e9. 据说……: It is said that从句一般认为……：It is thought that从句众所周知……：It is known that从句据报道……：It is reported that从句一般估计……：It is estimated that从句例众所周知,阅读增加我们的知识,开阔我们的心胸;=It is known that reading increases our knowledge and broadens our mind;10. ……的主要原因是……: The main reason why...is that从句例青少年犯罪的主要原因是社会环境逐渐恶化;=The main reason why the juveniles commit crimes is that social environment is becoming worse;经典句型1.
