sound strange to native speakers?

I want to know the following explanations is right.

Typical problem sentences
A. You can find a lot of ships in Pusan harbor. (X)
B. When I was a boy, we could see many hungry people in Seoul. (X)

This pattern is a very obvious direct translation from Korean. Sentences like the examples above are not ungrammatical in English, but they are very unidiomatic, and sound strange to native English speakers. A native speaker would express the same ideas like this :

A. ok - There are a lot of ships in Pusan harbor.
B. ok - When I was a boy, there were many hungry people in Seoul.

So, the solution to this Korean-English problem is very simple:
Tell the listener what THERE IS. DON'T tell him what he 'CAN SEE' (unless you happen to be an eye doctor)!
