Ellipsis02

省略句的定义省略前提:主谓宾,定状表,如有重复可删掉。省略是为了避免重复、突出新信息并使上下文紧密连接的一种语法修辞手段。省略在语言中，尤其在对话中，是一种十分普遍的现象。省略原则:词语省略后,不致令人费解。

省略句的目的避免重复，减少累赘。Mikesaidthathewouldcometoschooltoseemethenextday,buthedidntcometoschooltoseemethenextday.迈克说他第二天要来学校看我，但是第二天他并没有来学校看我。Mikesaidthathewouldcometoschooltoseemethenextday,buthedidnt.迈克说他第二天要来学校看我，但是他并没有来。连接紧密，结构紧凑。Johnwasthewinnerin1994andBobwasthewinnerin1998.约翰是1994年的获胜者，鲍勃是1998年的获胜者。

省略句的目的强调重点，突出信息。Truthspeakstoolow,hypocrisyspeakstooloud.真理讲话声太低，虚伪讲话声太高。—Haveyoutoldhimthat?你把那告诉他了吗?—Notyet.还没有呢。Ihavenottoldhimthatyet.强调notyet
