省略句：
一、省略的目的
省略多見于非正式文體，尤其在對話中，省略是一種普遍的現象。英語中的省略一般說來有三個目的：
1.避免重復，減少累贅。省略的主要目的是避免重復，去掉不必要的累贅和繁瑣。
mike said that he would come to school to see me the next day, but he didn't come to school to see me the next day.
mike said that he would come to school to see me the next day, but he didn't.
（省掉最后九個詞，句子簡潔了許多）
2.連接緊密，結構緊湊 省略也是使上下文緊密連接的一種修辭手段。
john was the winner in 1994 and bob in 1998.（bob 后省略了 was the winner，句子結構顯得比較緊湊）
3.強調重點，突出信息 省略的另一作用是突出新的信息
truth speaks too low, hypocrisy too loud.后一分句省略謂語 speaks，突出了 too loud）
二、句子成分的省略
為了避免重復，或者為了使某一內容引人注目，可以省略某些句子成分而保持句子原意不變。
1.省略主語
beg your pardon.請你原諒。（= i beg your pardon.））
serves you right. 你活該（= it serves you right.）
2.省略謂語
anything the matter? 要緊嗎？（= is anything the matter?）
the river was deep and the ice thin. 河很深，冰很薄。
（= the river was deep and the ice was thin.）
3.省略表語
are you ready? yes,i am.（am 后面省略了表語 ready）
4.省略賓語
we have to analyze and solve problems. (analyze 后省略了賓語 problems)
let's do the dishes. i'll wash and you'll dry.（wash 和 dry 后面省略了賓語 dishes）
5.省略定語
he spent part of the money, and the rest he saved.（the rest 后面省略了定語 of the money）
6.省略狀語
（even）the wisest man cannot know everything.
省略在句子中的應用
在一個句子中，省略可分為依賴上下文省略和不依賴上下文省略兩種。前者省略的部分可在句子中找到，但后者可能找不到。
1.簡單句中的省略
依賴上下文的省略在對話中最為常用。
like more beer?（= would you like more beer?）
—world you mind if i used your telephone?
—not at all. 一點也不。
（= i do not mind at all.）
—will he pass this examination?
probably. 大概會的。（= he will probably pass the examination.）
不依賴于上下文的省略。
all aboard! 請上船（= all go aboard.省略謂語）
haven't seen you for ages!（省略主語 i）
