系动词的分类及口诀有哪些
系动词就是将主语和对主语的说明部分联系起来,并对主语加以说明的词。以下是对英语系动词的归类及口诀的总结 ,大家一起来看看吧!
系动词的简单介绍
系动词是动词的一种,本身有词义,不可单独作谓语,后面必须跟表语构成系表结构:
主语+系动词+形容词(作表语)修饰主语的状态。要注意的是:如果句子是一般现在时,当主语是第三人称单数时,动词要变成单三形式。
系动词的分类
1、感官动词
Feel, smell, sound, taste, touch
This flower smells very nice.
2、状态系动词,表主语状态,只有be
He is a teacher.
3、持续性动词,表示主语继续或保持一种状况或态度
Keep, rest, remain, stay, lie
He always keeps silent at class.
4、变化系动词, 表示主语变成什么样
Become, grow, turn, fall, get, go, come, run
He became fat in winter holiday.
其实很多系动词可以当系动词,也可以当实义动词,但用法有所不同。如:Look
Look at my hand 实义动词,看
She looks amazing.系动词
英语系动词用法口诀
1.我用am,你用are,is连着他,她,它;
单数名词用is,复数名词全用are。
am,is变was. be是原形老妈妈。
not靠后变否定; be跑句首去问它。
2.要想掌握Be(am,is and are)的用法,先分清第一人称、第二人称和第三人称:
第一人称单数I(我) 复数We(我们)
第二人称you(你、你们)
其余都是第三人称:单数she(她) 、 he (他)、 it (它) 复数they(他们)
3.there be+宾语+过去分词:
过去分词表示被动关系,同时表示动作已经发生:
There is nothing written on it. 上面没写东西。
There were ten people killed in the accident. 事故中有10人丧生。
有时过去分词也可表示一种状态(可转换成被动结构):
There were some old men seated (=who were seated) in the back. 有些老人坐在后面。
There is a red car parked (=which is parked) outside the house. 房子外边停着一辆红色汽车。
4.there be+名词+现在分词:
现在分词表示主动关系,同时表示动作正在进行:
There is someone waiting for him. 有人在等他。
There was a man standing in front of me. 我前面站着一个男人。
There were some children swimming in the river. 有些小孩在河里游泳。
There were a group of young people working in the fields. 有一群青年在地里劳动。
有时现在分词可表示一种状态:
There’s a piano standing against the wall. 靠墙有一架钢琴。
There’re a lot of difficulties facing us. 我们面前有很多困难。
There is a door leading to the garden. 有一座门通往花园。
有个别现在分词用于该结构时可以表示将来(正如它们可用进行时表示将来一样):
There are ten people coming to dinner. 有10个人来吃晚饭。
5.there be+宾语+不定式:
不定式通常表示动作尚未发生
There was nobody to look after the child. 没有人照顾这孩子。
There was a large crowd to send him off. 有一大群人要来给他送行。
There was so much to lose that we couldn’t take any risks. 可能会有很大的损失,因此我们不能冒险。
当其中的宾语与其后的不定式为被动关系时,可用主动表被动,也可用被动式:
There is much work to do [to be done]. 有许多工作要做。
有时其中的不定式为系表结构:
There is nothing to be afraid of. 没什么可怕的。
What was there to be afraid of. 有什么可怕的?
