动词与介词、副词等构成的固定短语,叫短语动词。下面小编告诉你英语中动词短语用法,大家一起来看看吧!
英语中动词短语用法:
一、动词+副词
有的一般不跟宾语,如go ahead, fall behind, get up, lie down, go up, run out, give in, stay up等;有的可以跟宾语,如put out, carry out, give up, wake up, check in, eat up, fill in, find out, fix up, hand in, mix up, look up, make out, turn down, work out等。
注意:宾语是名词时,放在副词前面或后面都可以,但若作宾语的是人称代词时,就只能放在动词和副词之间了。如:
We’ve decided to put the meeting off (=put off the meeting) . 我们决定把会议推迟。
We’ve decided to put it off. 我们决定将它推迟。(不说put off it)

二、动词+介词
如ask for, care for, call for, break into, deal with, call on, look for等。后面必须接宾语。如:
I don’t care for tea. 我不喜欢喝茶。
三、动词+副词+介词
如look forward to, put up with, looked up to, go in for, go along with, date back to, look down on, keep up with, add up to, run out of等。如:
She soon caught up with us. 她很快赶上了我们。
四、动词+名词+介词
如take care of, pay attention to, make use of, make contribution to做出贡献等。如:
Take care of your brother while I am away. 我不在的时候,你要照顾好你弟弟。
improve in 与 improve on 的区别:
improve in 表示在某一方面有所改进或提高,improve on 表示在原有基础上进行改进或提高或做得比原来更好(其否定式意为已经够好了或无法再好了)。比较:
She improved in English. 她的英有进步。
He has improved in health. 他的健康状况已有好转。
He has never improved on his first book. 他再也没有写出比他的处女作更好的作品来。
比较下面两组句子:
He has improved her poem. 他已经修改了她的诗。
He has improved on her poem. 他写的一首诗比她的诗更好。
The poem cannot be improved. 这首诗没有什么可改的地方。
This poem cannot be improved on. 这首诗已经够好了,再也 写不出比这更好的了。
find out后面可接哪些成分:
其基本义为“打听”“了解”“查明”等,可以用于以下结构:
(1) 后接名词
We must find out the truth of the matter. 我们必须查明事实真相。
Can you find out his address for me? 你能帮我打听一下他的地址吗?
(2) 后接about引起的短语

(5) 后接 that 引起的从句

另外,find out还可表示“发现”(多指坏事),其后可接可数名词、代词、that从句,或不接任何成分。如:

You should tell her, because she’ll find out sooner or later. 他应该告诉她,因为她迟早会发觉的。
used to的基本用法以及与would的区别:
一、used to的基本用法
1. 其基本义为“过去常常”,注意以下用法:
(1) 一般不能与表示次数(如twice, three times等)或一段时间(如three months, five years等)的词语连用,但可与always, often, sometimes, never等频度副词连用。如:
I never used to watch television. 我过去从不看电视。
He often used to work late in the evening. 他过去经常工作到深夜。
这样用时,频度副词通常置于used 之前,但有时也可置于used之后。如:
I always used [used always] to be afraid of dogs. 我过去总是怕狗。
(2) 构成否定式和疑问式时有两种形式:借助助动词did(较口语化)或直接将used用作助动词(较正式)。如:
He usedn’t [didn’t use] to come. 他过去不常来。
You used to go there, usedn’t [didn’t] you? 你过去常到那儿去,是吗?
有时还可见到以下这种混合表达式,但不是很常用:
Did you use(d) to be a teacher? 你过去是当老师的吗?
There used to be some trees in this field, use(d) n’t [didn’t] there? 这一片地曾有些树,是吗?
They didn’t use(d) to live here. 他们过去没住在这儿。
二、used to与would的区别
(1) 两者均可表示过去习惯性的动作,有时可互换。如:
When we were children we would [used to] go skating every winter. 我们小时候,每年冬天都去溜冰。
(2) 当要表示过去持续的状态或表示过去与现在的对比(即“以前这样,但现在不这样了”)时,则要用used to。如:
Sex is no longer the taboo subject it used to be. 现在不再像过去那样把性的问题视为禁区。
Women used to think they were on the shelf at 30. 过去女人一到30岁就认为是过了结婚年龄。
I used to cook on electricity, but I’ve switched to gas. 我过去用电煮饭,但现已换成用煤气了。
