• normal 本词

  The general, neutral word for what is expected or typical in a situation, especially feelings, health or behavior; commonly used in the pattern 'It's normal to...', without any statistical or scheduling sense.

  泛指符合预期或典型的普通说法，尤其用于描述感受、健康或行为，常见于陈述某事很正常的固定句式，不涉及统计或规律性的含义。

  It's normal to feel nervous before a big test.

• average

  Describes what is typical of the middle of a group, often based on a real or implied statistic; can suggest merely ordinary rather than special, unlike the more neutral 'normal'.

  描述处于群体中间水平的典型情况，往往基于实际或隐含的统计数据，语气可能带有普通、不特别的意味，比更中性的 normal 更强调统计上的一般水平。

  普通学生每天晚上花两个小时做作业。

• regular

  Describes something that happens on a fixed schedule or conforms to a set standard; stresses habitual repetition or conformity to a rule, not simply being typical or common.

  描述按照固定时间表发生或符合既定标准的情况，强调习惯性的重复或对规则的遵循，而不仅仅是常见、典型。

  He goes for a regular walk in the park every morning.

  他每天早晨都会去公园进行一次例行散步。

Normal, average, and regular all mean usual or typical, but differently: normal means expected and not unusual; average means typical for the middle of a group, based on a statistic; regular means following a fixed schedule or habit. Other meanings are not compared here.

这三个词都能表示正常的、普通的，但侧重点不同：normal 强调符合预期、不异常；average 强调处于群体的平均水平，语气略带普通、不特别的意味；regular 强调按照固定规律或标准发生，常指习惯性的行为。这里不比较 average 表示平均数的名词用法，也不比较 regular 表示标准尺码或正规的等其他用法。
