barren 和 sterile 的差別在哪裡？如果不好說明，請提供一些例句。

Barren is usually used to talk about a place that is empty where nothing grows.
"The desert land is very barren."

Sterile means a place where plants can't grow, so they are often used the same way.
"We can't grow anything because the land is sterile."

Sterile can also mean something is very clean or has no bacteria on it. Usually this is used when talking about something medical.
"Doctors always use sterile syringes."

Both barren and sterile can also mean unable to reproduce.

Sterile is used more commonly and can refer to people (usually men) or animals.
"Our cats are sterile, so they can't have kittens."

Barren I think is less common and is usually used only to talk about women who can't reproduce, but is also used to talk about a plant that doesn't produce fruit.
"Our apple tree is barren and doesn't produce any fruit."

Sorry for the long explanation, hope this helps! 😄
