频率副词：“从不”、“总是”以及介于两者之间的所有表达
如果你学英语已经有一段时间，你可能知道我们有很多表达「事情发生频率」的方法。你always吃早餐吗？你sometimes会跳过每天的锻炼吗？
我们来谈谈七个常见的频率副词：always, often, usually, sometimes, occasionally, rarely, and never。这些小词在日常对话中很常用，一旦掌握，你会听起来更自然。
频率副词：它们放在哪里？
在看例子之前，先记住基本规则：大多数频率副词放在before the main verb，但放在系动词后面——也就是after the verb "to be."
I always drink coffee in the morning. (在主要动词之前)
She is always on time. (在“is”之后)
明白了吗？我们来看每个词的具体用法。
Always (100%的时间)
这个很简单。如果你 always 做某事，表示你每次都会做。
I always check my email before class.
My students always ask good questions when they're confused.
想想那些在任何情况下、每天都会做的事。也许你总是在睡前刷牙；也许有人为你开门时你总会说 "thank you"。这就是可以用 always 的情形。
Usually (大多数时候，但并非每次都如此)
Usually 表示大多数情况下会发生，但有例外。
I usually take the subway to work, but sometimes I walk if the weather is nice.
We usually finish our lesson around 8 PM. (如果当天问题很多的话，也许我们可以稍后再上完这节课。)
你通常做什么？也许你 usually 在中午吃午饭，但忙的时候会晚一些。

Often (很多，但不如“通常”那么确定)
Often 和 "usually" 类似，但听起来没那么肯定。它只是表示某事发生很多次。
I often listen to podcasts during my commute.
My students often mix up "since" and "for."
想想你的习惯。你 often 在睡前刷社交媒体吗？你 often 重看喜欢的剧吗？
Sometimes (大约一半的时间)
Sometimes 比较灵活。表示某事会发生，但不是有规律的。它也可以放在句首。
Sometimes I cook dinner, and sometimes I order takeout.
I sometimes forget to reply to text messages.
你 sometimes 做什么？也许你有时去健身房，但只有在有精力的时候才去。
Occasionally (少于“有时”)
Occasionally 表示偶尔、间或发生，但不常见。比 "sometimes" 听起来稍微正式一点。
I occasionally treat myself to a fancy coffee on the weekend.
We occasionally have surprise quizzes in class.
你 occasionally 做什么？也许你偶尔去参观博物馆，或者偶尔请自己吃一顿贵的晚餐。

Rarely (几乎从不)
Rarely 表示某事发生，但频率很低。它是 "often" 的反义词。
I rarely watch TV nowadays. I prefer reading.
My students rarely miss class, which I really appreciate.
你 rarely 做什么？也许你很少吃快餐，或者很少熬夜到午夜以后。
Never (0%的时间)
Never 表示完全不会发生。零次。
I never drink coffee after 6 PM. If I did, I wouldn't sleep.
She never arrives late to class.
你 never 做什么？也许你从不不吃早餐，或者从不离家忘带手机。
把它们放在一起看
让我们想象一个名叫 Maria 的学生，看看这些副词如何描述她的生活：
Maria always goes to work Monday through Friday. (She never misses a day.)
She usually takes the bus, but she occasionally drives when it's raining.
She often eats lunch at her desk while she studies English vocabulary.
Sometimes she meets friends after work, and sometimes she goes straight home.
She rarely eats dinner after 9 PM.
She never skips her English practice.
看到了吗？每个副词都给我们不同的频率信息。没有这些词，我们得说 "She goes to work every day" 和 "She takes the bus most days"，那样会更啰嗦。频率副词让表达更简洁、更容易理解。
