英语语法:频率副词用法小结

沪江2018-08-21 10:42

  如果我们将频率副词放在句子的开头或结尾表示强调,则情况并非如此。而且此规则也不适用于简短回答:

  Is she usually on time?

  她通常准时吗?

  Tell her not to be late.

  告诉她不要迟到。

  Yes, she usually is.

  是的,她通常是。

  She never is.

  她从来不。

  如果句子中有多个动词(例如助动词),我们通常将频率副词放在第一个动词之后:

  subject / helping verb or modal / adverb / main verb / predicate

  主语/助动词或情态动词/副词/主动词/谓语

  I can never forget his name.

  我从来都不会忘记他的名字。

  Anne doesn't usually smoke.

  安妮通常不抽烟。

  The children have often complained about the playground facilities.

  孩子们经常抱怨游乐场的设施。

  例外:

  在含有“have to”的句子中,频率副词位于所有动词之前:

  subject / adverb / have to / main verb / predicate

  主语/副词/have to/主动词/谓语

  We often have to wait for the bus.

  我们经常要等公共汽车。

  She never has to do any housework.

  她从不做任何家务。

  为了表示强调,我们可以将频率副词放在句子的开头或结尾。

  首先,把它放在最后是很少见的。我们通常只在我们忘记把它放在开头时才把它放在结尾。

  adverb / subject / main verb / predicate

  副词/主语/主动词/谓语

  Sometimes we go to school by bus.

  有时候我们乘公共汽车上学。

  Often he waits for her after class.

  他经常在课后等她。

  subject / main verb / predicate / adverb

  主语/主动词/谓语/副词

  We go to school by bus sometimes.

  我们有时乘公共汽车去学校。

  They like to watch TV often.

  他们经常喜欢看电视。

  例外情况:

  “Always” 不能放在句子的开头或结尾。

  “Never”,“seldom”,“rarely”不能放在句子结尾。他们只用于“陈述”的句子开头。然后他们必须遵循疑问句的词序:

  Never has there been a better time to overcome our differences.

  从未有过比这更好的时机来克服我们的分歧。

  Rarely do we have an opportunity like this.

  我们很少有这样的机会。

  在疑问句中使用频率副词时,请将副词放在主动词之前:

  auxiliary verb / subject / adverb / main verb / predicate

  助动词/主语/副词/主动词/谓语

  Do you often go to the cinema?

  你常去电影院吗?

  Do they usually come late to class?

  他们经常上课迟到吗?

  例外:

  “Never”,“seldom”,“rarely”以及带有否定含义的其他频率副词通常不会在疑问句中使用。

  当在否定句中使用频率副词时,请将频率副词放在主动词之前:

  Subject / helping verb / adverb / main verb / predicate

  主语/助动词/副词/主动词/谓语

  They don't often go to the cinema.

  他们不经常去电影院。

  Peter doesn't normally want to come with us.

  彼得通常不想和我们一起来。
