及物动词和不及物动词的最大区别？

及物动词 后面必须跟宾语意义才完整的实义动词，叫做及物动词(transitive verb)。
不及物动词 本身意义完整后面不须跟宾语的实义动词，叫做不及物动词(intransitive verb)。

分清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.
Please hand me the book over there.
They asked me to go fishing with them.
类似的还有：buy, catch, invent, found, like, observe, offer, prevent, promise, raise, find, forget, receive, regard, see, say, seat, supply, select, suppose, show, make, take, tell....

b．主要用作不及物的动词。不及物动词后面不跟宾语。只能用与："主＋谓"结构。
This is the room where I once lived.
类似的还有：agree, go, work, listen, look, come, die, belong, fall, exist, rise, arrive, sit, sail, hurry, fail, succeed....

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, close, consider,
