Mẫu sử dụng:
limestone [rock/cliff/building/soil]
Lỗi thường gặp:
Learners sometimes treat 'limestone' as a regular countable noun and say *a limestone* when they should say 'a piece of limestone' or 'a block of limestone'. Another confusion is thinking that 'limestone' and 'chalk' are always the same; chalk is actually a specific soft type of limestone.
Từ đồng nghĩa

|

Từ trái nghĩa
