四、同等成分的一致
1．句子的同等成分应该在结构上保持一致
如：误：Sleep, rest and relaxed are the best remedies for many headaches.
正：Sleep, rest and relaxation are the best remedies for many headaches.
睡眠、休息和娱乐是治疗多种头疼的最好办法。
2．在比较结构中，被比较的事物应该是同等成分。
如：误：The climate of Beijing is not so pleasant as Dalian.
正：The climate of Beijing is not so pleasant as that of Dalian.
北京的气候不如大连的好。 二．省略
为了避免重复，使语言简练紧凑，在不起误解的情况下，将一个句子中一个或多个成分省去，这样的句子叫做省略句。
1．省略主语
通常用在祈使句或口语中的固定表述中。
如：Have a good time.愿你过得愉快！
Hurry up!快一点。
2．省掉行为动词或系动词
如：Sophia is brighter than her brother.苏菲亚比她弟弟聪明。（brother后面省略了is）
Some of us study French, others German.我们有的学法语，有的学德语。（others后面省略了study）
3. 省略表语
如：Are you ready?
Yes, I am.(am后面省略了ready)
4．同时省略句子几个部分
如：She likes reading better than going to parties.她爱读书而不爱去参加聚会。（than后面省略了she likes）
Have you ever been to Hong Kong ?
Never.(=I have never been there)
You are a college student, aren’t you? ( =aren’t you a college student?)
Has she gone or not? (=Has she gone or has she not gone?)
注：在以if, when, where, though, as, as if等连词引导的从句中，如果从句中的动词是be, 可以将主语和动词be省掉。
如：Fill in the blanks with the given words. Change the form where necessary.
用所给的词填空，必要的地方可以改变其形式。（where之后省略it is）
He looks as if drunk.他看起来好像是喝醉了酒似的。（=as if he were drunk）
5.省掉不定式
1)省略了不定式后面的动词
如：Would you like to go shopping?
Yes, I’d love to.(to 后面省略了go shopping)
2）省略了不定式符号to
两个或两个以上的动词不定式在一起，第一个不定式带to,后面的不定式可以省去to
如：Her work is to look after the child and (to) cook.她的任务就是看孩子和做饭。
但是如果两个不定式之间有对比关系，则不可以省去to.
如：To go home or to stay at school during the summer vacation is not decided.暑假回家还是呆在学校还没有决定。
三、倒装的用法
英语中的句子语序通常是主语在前，谓语在后。这种语序是正常语序。但是出于语法或达到某种修辞目的的需要， 要把谓语动词放在主语前面，这种语序叫做倒装语序。如果把谓语动词完全移至主语之前，成为完全倒装；如果把助动词或情态动词放在主语之前，成为部分倒装。
如：Out rushed the boy.那男孩冲了出去。（完全倒装）
Never before have I heard such a thing.我以前从未听说这样的事情。（部分倒装）
1．语法倒装
1）在问句中。
如：Are you free Saturday evening? 你周六晚上有空吗？
注：若特殊疑问词作主语或修饰主语，则仍采用正常语序。
如：Who is on duty today ? 今天谁值日？
2）在there be或there + appear to be, come, exist, happen to be, occur, seem, used to be等结构中。
如：There happens to be nobody in the room.碰巧房间里没人。
There occurred an unusual thing at that moment.那时发生了一件不平常的事情。
3）在以here, there, now, then等简短副词开头的句子中，动词是come, go, be等时，需要倒装。
如：Here comes the bus.公共汽车来了。
There goes the bell.铃响了。
但是如果主语是人称代词，则不用倒装。
如：Here they are.他们在这儿。
4）虚拟结构中的条件从句省去if时，这时were, had, should须移至主语之前。
如：Had you worked harder at college, you would have got a better job.如果当初你在大学读书的时候用功些，现在就会找个好点的工作。
Were he better qualified, he would apply for the position.要是他的条件好些，他就申请这个职位。
5）在用so, nor, neither表示“也/也不……”这一类结构里，语序是：
肯定：so+ 助动词/情态动词+主语
否定：neither(nor)+ 助动词/情态动词+主语
如：He has been to Beijing.
So have I . 他去过北京。我也去过。
They can’t answer the question.
Neither can I . 他们不会回答这个问题。我也不会。
注：so如果用于只是对前面的话表示确认，不表示前句的内容也适用于另外一个人或物，此时不用倒装。
如：It was cold yesterday.
So it was.昨天很冷。 是的，确实很冷。
6）在“the more…the more…”结构中，宾语、表语或者状语提前。
如：The more books you read, the wider your knowledge is.书读得越多，知识就越渊博。
（宾语提前） （表语提前）
The harder you work, the greater progress you will make.你越努力学习，取得的进步就越大。
（状语提前） （宾语提前）
2．修辞倒装
1）当only位于句首修饰状语（副词、介词短语或状语从句），表示强调时，要用倒装。
如：Only in this way can you solve this problem.只有用这种方法，你才可以解决这个问题。
Only when he told me did I realize what trouble he was in.直到他告诉了我，我才意识到他遇到了麻烦。
但是如果only位于句首，修饰的不是状语而是主语，则不用倒装。
如：Only you know this.只有你知道这件事。
2）具有否定意义的副词或词组，用于句首，要用倒装。常见的这部分词或词组有：never, seldom, hardly, little, not until，by no means, under no circumstances等。另外还有否定意义的关联词：not only…but also, neither…nor, no sooner…than, hardly…when,位于句首，也要倒装。
如：Never shall I forget the days when you were with us.我将永远不会忘记你和我们相处的那些日子。
Not until then did he realize his own fault.知道那时他才意识到自己的过错。
Under no circumstances should you lent him any money.你无论如何都不该把钱借给他。
No sooner had we reached home than it began pouring.我们刚到家就下起了倾盆大雨。
3）在表示动作的简短的句子里，为了表达生动，有时把副词放在句首，同时把谓语动词放在主语之前。这类副词有away, down, in , out, up等
如：Away went the runners.赛跑手们刷地跑开了。
Down came the rain.雨哗地落下来了。
注：在此结构中，如果主语是人称代词，则用正常语序。
如：Out he rushed.他冲了出去。
4）由as, however引导的让步状语从句，将作表语、状语或谓语的一部分形容词、名词、副词或动词前置，表示强烈的对照。
如：Tired as he was, he continued the work.虽然他累了，但是仍然继续工作。
Try as he might, he could not fulfill the task alone.不管他如何努力，他还是无法独自完成任务。
However busy we are, we should have some time for rest.不论我们多么忙，我们总应该有休息的时间。
注：as引导让步状语从句，如果谓语是系表结构的，且名词、最高级作表语时，将表语提前，略去冠词。
如：Child as he is= Although he is a child.
Youngest as he is = Although he is the youngest.
从句中除了表语提前外，如果主语是名词，主语和谓语一般也要倒装；主语是代词，不用倒装。
如：Terrible as was the storm, we continued our way.尽管暴风雪很大，我们仍然继续前进。
Poor as he was, he was honest.他虽穷，但却诚实。
5）介词短语做地点状语，放在句首，后面跟的是不及物动词be, exist, stand, come, sit,lie等
时，要倒装。
如：Over the wall came a shower of stones.越过墙头丢来一阵石块。
At the corner stands a man selling newspaper.街角上站着一个卖报的男人。
6）在“so/such…that”结构中，如果so /such放在句首加强语气，需要倒装
如：So angry was he that he couldn’t speak.他如此愤怒，以致说不出话来。
Such was the force of the explosion that all the windows were broken.那个爆炸的力量如此之大，以致所有的窗户都震破了。
