请随手关门英语

throw one's support behind sb 在某人背后支持某人语法点是behind作为方位词使用，意为“在后面”介词 behind 用法说明behind 主要用作介词,但除此之外,它也用作副词,在使用时以下几点值得注意：1. 用作介词表示位置时,通常是静态的,但有时也可能是动态的.如：The sun disappeared behind the clouds. 太阳躲到云层后面去了.有时若没有上下文,同一个句子可能有几种理A mouse scuttled behind the curtain. 理解1：一只老鼠跑到窗帘后面去了.理解2：一只老鼠从窗帘后面跑走了.理解3：一只老鼠在窗帘后面窜来窜去.2. 表示“通过（房门、大门等）之后”这一意义时,有人认为应换成after,并作出以下区别 ：Shut the door after you. 请随手关门.（表动态地进门或出门之后）Shut the door behind you. 把你后面的门关上.（表静态的后面）其实,现代英语并不按此区别(www.yygrammar.com).3. 表示未能如期完成某事,通常用be behind with [in],此时的 behind 为副词.如：He is never behind with [in] his work. 他工作从不拖拉.He was behind in [with] his rent. 他拖欠了房租.若后接动词,则用动名词.如：The boy is behind in handing in homework. 这孩子没能按时交家庭作业.He was never behind in offering suggestions. 他提建议从来不落在别人后面.4. 注意以下几个短语的用法(其中的 behind 是副词,不是介词)：(1) fall [drop] behind 落在后面.如：I’ve fallen behind in work. 我工作落后了.Some students dropped behind in their studies. 有的学生在学习上落在后面.(2) leave sth behind （某人）走后留下（掉下）某物.如：What have we left behind? 我们走后留下什么了?He left his umbrella behind. 他离开时没有把雨伞带走.(3) stay [remain] behind 留下,在别人后面留下.如：He alone remained behind. 只有他一个人留下没走.I had to stay behind after school. 放学后我还得留在学校.
