频度副词置何处

来源:  作者:admin  (查看评论)
英语中回答"经常与否"的副词称为频度副词(Adverbs of Frequency)。
频度副词主要有: always,usually,sometimes,occasionally,seldom,never,generally,frequently,hardly,ever,never,rarely,
constantly,continually,scarcely 等。
频度副词有的表示动作的经常性或事物的经常状态,有的表示动作的不规则的反复。频度副词在句子中的位置常常因谓语动词的不同而变化。其基本规律如下:
1.当句子的谓语动词是行为动词时,频度副词一般放在谓语动词之前。例如:
I hardly ever heard her singing.我几乎从未听她唱过歌。
2.有时为了达到对比或强调的目的,频度副词也可以放在句首。例如:
Sometimes he goes to school by bus and sometimes he cycles to school.有时他乘车去上学,有时骑车去上学。
3.never,seldom,rarely,scarcely 这类表示否定意义的频度副词置于句首时,句子要倒装。例如:
Never in my life have I heard or seen such a thing. 有生以来我从未听到过或见到过这种事情。
4.often 在被very 或者quite 修饰时,要放在句末。例如:
I didn't write to my mother very often. 我不常给母亲写信。
但有时为了行文流畅或特别强调,quite often 和very often 也可以放在句首。例如:
Very often the wind was too strong for us to go out. 经常由于风太大我们不能出去。
5.当句子里有情态动词或助动词时,频度副词要放在这类动词的后面。例如:
This job will never be finished.这项工作永远也完不成了。
I do not often have headache.我不常头痛。
但是,当这些情态动词、助动词需要强调时,频度副词要放在它们之前,朗读时要重读情态动词及助动词。例如:
They always can find time for English. 他们总能找到时间学习英语。(can 应读强式[k n])
-Why don't you stop smoking?
-你为什么不戒烟?
-But I never have smoked.
-我从来也不吸烟。(have要读强式[h v])
6.have to 表示客观需要的"不得不"时,虽相当于情态动词,但频度副词要放在它之前。例如:
I often have to get up at five. 我经常得五点钟起床。
7.当句子中有used to 这个"临界性情态动词"时,频度副词既可以在其前也可以在其后。例如:
We always used to go to the seaside in May.
We used to always go to the seaside in May.
那时候,我们总是五月份到海滨去。
