英语中的省略
英语中的省略为了避免重复，英语句子中某些部分可以省略。
常见的省略有以下几种：一、状语从句中的省略在时间、条件、让步及比较状语从句中，如主句和从句主语一致（或从句主语是it），且从句含be动词时，可将从句中的主语和be动词省略，从而构成“连词+ 分词/形容词/副词/介词”结构。
这里常见的连词有when/while/as/if/unless/once/although/though/than等。
When (water is )heated, water is turned into vapor. 水加热时变成气体。
He works very hard though（he is）rather weak. 他尽管体弱，但他十分努力地工作。
He came earlier than（he had been）expected. 他来得比预料的要早。
考例：①The research is so designed that once ____ nothing can be done to change it.A. beginsB. having begunC. beginningD. begun②If you go to Xi' an, you will find the palaces there more magnificent than commonly ___ .A. supposingB. supposedC. to supposeD. suppose分析：①D。
once后省略了the research is begun ②B。
比较状语从句中的完整形式是：than they are commonly supposed。
二、并列结构的省略1.并列结构一般由and, or, but等连接，他们可以连接单词、短语或分句，其中相同成分出现时可以被省略。
One of the sides of the board should be painted yellow, and ____.A.the other is whiteB. another whiteC. the other whiteD. another is white选C。
英语中状语从句的省略规则
在英语的实际应用中，有时上下文或当时的语境能够帮助我们理解所写的内容，所以有的时候可以省去一个或更多的句子成分，但前提是不影响句子的理解和可读性，因此若有具体的上下文支撑，是可以省去部分成分。
跟定语从句的“瘦身”原理类似，状语从句也可以“瘦身”，这种“瘦身”原理就是省略。
若从句的主语与主句的主语一样，那么通常可以省略从句的主语或助词，然后动词做相应的变化，例如：While Sarah was studying, she fell asleep.萨拉在学习时睡着了。
解析：此句可以省略，因为从句中的主语和主句中的主语都是 Sarah，因此可以省略为 While studying, she fell asleep，但是以下这句不能省略，例如：While Sarah was talking, I fell asleep.萨拉说话的时候，我睡着了。
解析：从句中的主语 Sarah 和主句的主语 I 不一样，所以不能省略。
一、状语从句带 be 动词的省略在带 be 动词（am, is, are, was, were, been, being）的状语从句中，直接省略主语和 be 动词，例如：1. 萨拉在学习时睡着了。
While she was studying, Sarah fell asleep.省略：While studying, Sarah fell asleep.2. 尽管他迟到了，他还是被允许去看电影。
Although he was late, he was admitted to the movie.省略：Although late, he was admitted to the movie.二、状语从句不带 be 动词的省略在不带 be 动词（am, is, are, was, were, been, being）的状语从句中，直接省略主语，然后把对应的动词变成 -ing 形式，例如：1. 杰克读完这本书后，把它放回书架上。
状语从句的省略
一般来说，省略现as, before, after, till, until, once等引导 的时间状语从句；由if,unless等引导 的条件状语从句；由though, although,even if, whatever等引导 的让步状语从句；由as,than 引导的 比较状语从句；由as, as if, as though引导的方式状语从句。
1.当状语从句的主语和主句的主语一致时，可以省 略从句中的主语和系动词be,这时从句从句中可 以出现以下结构：
连词+名词 连词+形容词 连词+介词短语 连词+现在分词 连词+过去分词 连词+不定式
• 请看下面的句子： 1. Though( he is) a young boy, he has a good command of computer. 2. Though (he is) tired, he is still working hard. 3. He looked everywhere as if (he was) in search of something. 4. He opened his mouth as if (he were) to speak. 5. While (my father was) watching TV, my father fell asleep. 6. The maths problem is more difficult than (it was) expected.
2. 当从句中的主语是it, 谓语动词中又含有系
动词be, 可以把it 和系动词be一起省略。 此时构成“连词（if, unless, when, whenever) +adj.”的结构 例如：
