常用的頻度副詞
在英文中，表示經(jīng)常性或習(xí)慣性的行為時(shí)常使用頻度副詞。常用的頻度副詞有：always（總是）， usually（通常），often（經(jīng)常），sometimes（有時(shí)），seldom（很少），never（從不）。
表示頻度方面的區(qū)別
1. always是頻度最大的詞，意為“總是；永遠(yuǎn)”。
I always remember my first day at school.
They always help others.
2.usually意為“通常”，即很少例外，頻度僅次于always。
What do you usually have for breakfast?
He usually plays basketball on Saturday morning.
3.often 意為“經(jīng)常”,在頻度上不如usually那么頻繁。
Li Ping often does his homework in the afternoon.
I often get up at five past six.
4.sometimes 意為“有時(shí)候”,頻度比often小,表示動(dòng)作偶爾發(fā)生,間斷較大。既可以放在be動(dòng)詞、助動(dòng)詞之后,行為動(dòng)詞之前,也可以放在句首,還可以放在句尾。
I sometimes go to the library. Sometimes I read a book in the evening.
5.never 從未；永不；決不。
I have never been there.
You must never tell him.
