次数表达法

用次数+时间段回答，
“once/twice/three times… a day/week/month/year…”
用时间短语回答，

3. 频度副词 (Adverbs of Frequency)
频度副词表示事情发生的频率， 可用来回答how often引导的问句。 常用的频度副词有always，almost always， usually，often， sometimes，hardly ever（seldom），never等，它们在频度上的差异可以这样表示：
always(100%)>almost always>usually>often>sometimes>hardly ever(seldom)>never(0%)
频度副词通常放在动词前面，若句子里有情态动词、助动词或系动词be,则放在这类动词（第一个）的后面。例如：
It's always interesting to watch other people show their talents.
Why do people usually make resolutions
When we watch movies about the future, we sometimes see robots.
They hardly ever watch TV.
Fewer people will do such jobs in the future because they are boring, but robots will never get bored.
