ever的用法总结

can ever be用法

我们来看两个句子

  • can the magnitude of the instantaneous velocity of an object ever be greater than the magnitude of its average velocity?
  • can it always be greater?

这里can ... ever be是疑问句,表示经验性询问。即,是否存在这种可能,是否可能存在某一刻瞬时速度大于平均速度

always表示一直,整个过程中瞬时速度一直大于平均速度

我在这里吐槽下自己,居然误解can ever be为一直,瞬时速度一直大于平均速度。
面壁思过。。。

ever 用法

根据doctionary.cambridge.org的解释
every,adverb,意思是at any time

疑问句例句:

表达存在可能性

  • has he ever scored a goal before? 他之前是否进过球(表达存在性,并不要求一直进球,只是是否进过)
  • do you ever dream about winning the lottery? 你是否梦见过中彩票(表达存在性,是否做过中彩票的梦)
  • have you ever heard the Ivy restaurant? 你是否听说过Ivy餐厅(表达存在性,听过一次也是听过)

否定句

表示从来没有
我们可以在否定句中使用not ... ever,但是更常见的情况是我们会用never

  • Tom doesn't ever call me at weekends. 或者 Tom never calls me at weekends.
  • We haven't ever had a problem with noise in the neighborhood before. 或者We have never had a problem with noise in the neighborhood

否定句中与no one, nobody, hardly联用

  • No one ever told me what had happened
  • We have hardly ever eaten Vietnamese food. (我们几乎没有吃过越南菜)

if .. ever用法

表示假设条件

  • if ever you move house, I'd advise you to get a good removal company. (如果你搬家,我建议你找个好点的搬家公司)

  • if you ever go to Washington, make sure to visit the Art Gallery.

  • If you are ever in Winnipeg, we should get together and have a party.

ever so和ever such

表示强调语气

  • I feel ever so cold. 我【TMD】(这里不是在叫大家说脏话,只是强调一下语气)好冷啊
  • He was ever such a kind man. 他【TMD】(这里不是在叫大家说脏话,只是强调一下语气)曾经是个很好的人

ever since用法

我们在since前面加上ever来强调从某一刻起某一事实成立

  • ever since we met, we have been such great friends. 从我们见面那天起,我们就已经是很好的朋友了
  • Mrs Tom doesn't go for walks on her own ever since she fell. 自从摔倒之后,Tom就再也不独自去散步了。

as .... as ever用法

表示比较

  • it's as busy as ever. 和往常一样忙
  • They've built a new road around the city but traffic is as bad as ever. 他们在城市周围修了一条新路,但是交通还是和过往一样的差

ever表达always

在非常正式的场合,ever联用形容词可以表达always的意思

  • the company cannot sustain ever-decreasing profits. 公司无法在一直亏损的情况下支撑下去
  • Tom was ever available to help the family. Tom一直有空去帮助邻居

一些说不清楚的情况,lol,毕竟现有语言后有语法

  • happily ever after. 这里ever就表达always
