不及物动词
英语中按动词后可否直接跟宾语,可把动词分成不及物动词与和及物动词。
不及物动词:字典里词后标有vi. 的就是不及物动词。不及物动词后不能直接跟有动作的对象(即宾语)。若要跟宾语,必须先在其后添加上某个介词,如to,of ,at后方可跟上宾语。具体每个动词后究竟加什么介词就得联系动词短语了,如listen to,look at….
如:look 看 (vi.) x宾语(即不能直接加宾语). Look! She is singing.
Look carefully! (注意:carefully 是副词,不是名词,故不作宾语)
look at 看…….+宾语 Look at me carefully! (me是代词,作宾语)
at是小范围 in是大范围
如:
The students work very hard.学生们学习很努力。
She apologized to me again. 她再次向我道歉。
The accident happened yesterday evening.事故是昨天晚上发生的。
分清及物不及物动词:
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。只能用于:"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, insist, read, learn, prepare, pay, hurt, improve....
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:beatvi.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
ringvi.(电话、铃)响vt.打电话speak vi.讲话vt. 说(语言)
hangvi. 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.
