及物不及物 词义大不同

You Aim It Too Plea.英语词汇网 .wbw.. 20060612113915英语词汇网 .wbw.. 20060612113915
你知道它的意思吗?这里的关键词是aim，这两个aim的词义和用法不一样，第一个aim是不及物动词，意思为"旨在,目的是"，第二个aim是及物动词，意思是"使...瞄准"．另外，这两个plea的含义也不一样，第一个是不及物动词，意为"使人高兴"，第二个是副词，意思是"请"，it在这里是"大小便"．这两句抽韵话的意思是:我们想让你高兴，也请你便时瞄准．这种诙谐的标语，目的是告诉人们要自觉保持厕所干净，不要便在池外．英语词汇网 .wbw.. 20060612113915英语词汇网 .wbw.. 20060612113915

动词的及物不及物是在英语学习中必须解决的首要问题。动词及物与不及物通常有以下几
种情况：
a．主要用作及物动词。及物动词后面必须跟宾语。可以用于："主＋谓＋宾"；"主＋谓＋双宾"；"主＋谓＋宾＋宾补"结构。如：
He reached Paris the day before yesterday.
Plea hand me the book over there.
They asked me to go fishing with them.
类似的还有：buy, catch, invent, found, like, obrve, offer, prevent, promi, rai, find, forget, receive, regard, e, say, at, supply, lect, suppo, show, make, take,
b．主要用作不及物的动词。不及物动词后面不跟宾语。只能用于："主＋谓"结构。
This is the room where I once lived.
类似的还有：agree, go, work, listen, look, e, die, belong, fall, exist, ri, arrive, sit, sail, hurry, fail,
c．既可以用作及物又可以用作不及物的动词，其意义不变。如begin 都是作"开始"讲。everybody , our game begins. let us begin our game. 类似的还有：start, answer, sing, clo, consider, insist, read, learn, prepare, pay, hurt,
d．既可以用作及物又可以用作不及物的动词，其意义完全不同。
这类动词作不及物动词是一个意义；而作及物动词时却是另一个意义。如lift作不及物动词时是指烟雾的"消散"。we saw the mountain when the clouds lifted. 作及物动词时是"升高；举起"。
He lifted his glass and drank.
类似的还有：beat vi.跳动 vt. 敲、打; grow vi.生长 vt. 种植
play vi.玩耍 vt. 打（牌、球）,演奏 smell vi.发出（气味） vt. 嗅
ring vi.（、铃）响vt.打 speak vi.讲话 vt. 说（语言）
hang vi. 悬挂 vt. 绞死 operate vi.动手术 vt. 操作
需要注意的一点是：少数不及物动词唯一可跟的宾语是同源宾语，如：I dreamed a dream last night.
