  • 频度副词

频度副词的概念

频度副词表示动作发生的次数,常见的有ever, never, rarely, seldom, once, often, occasionally, constantly, frequently, usually, continually, always等。


频度副词的特点:

频度副词表示动作发生的次数,常见有的ever, never, rarely, seldom, once, often, occasionally, constantly, frequently, usually, continually, always等。

频度副词在句中的位置:

频度副词通常位于实义动词之前,动词be、助动词、情态动词之后:
如:He often comes to see us. 他常来看我们。
        He is seldom late for school. 他上学很少迟到。
有时为了强调,频度副词也可位于动词be、助动词等之前:
如:She always was late. 她老是迟到。
有的频度副词可位于句末(尤其受very, only修饰时):
如:I get paid on Fridays usually. 我通常在星期五领工资。
        We go out very seldom. 我们绝少外出。
        Do you go to the cinema very often? 你常去看电影吗?
有的频度副词(如sometimes, often, usually, frequently, occasionally等)可位于句首(此时多半是因为强调或对比):
如:Sometimes he went there by bus. 有时他坐公共汽车去那儿。
        Very often the phone rings when I'm in the bath. 电话经常在我洗澡时响。
:含有否定意义的副词置于句首时,其后要用倒装语序:
如:Never have I been there. 我从未去过那儿。
        Seldom does he see a film. 他很少看电影。
另外,频度副词always和never通常不位于句首,除非是祈使句:
如:Always remember this. 时刻记住这一点。
        Never go out at night. 晚上千万不要出去。

频度副词在否定句中的位置:

在否定句中,有的频度副词可位于否定词not之后或之前(如usually,often),有的频度副词则必须位于否定词之后(如always, constantly, continually, continuously,均含有“连续不断”之意),而有的频度副词却必须要位于否定词not之前(如sometimes, frequently):
如:He doesn't usually come here./He usually doesn't come here. 他通常不来这儿。
        She doesn't always comelate. 她并非总是迟到。(不能说alwaysdoesn’t)
        He is sometimes not responsible for what he does. 他有时对他所做的事不负责任。
