Chapter 1 可数与不可数名词及其使用


可数名词: 有清晰的边界且可被视为独立体

If a noun can be counted, it will have a clear boundary (physically or conceptually) and will be seen as a separate entity.

不可数名词: 无边界或极限

An uncountable noun means no boundary or limit can be formed for it; that is why these nouns are commonly qualities, feelings, and social processes.
