Does students whouse English as their second language have to make extra effort to use the language?
When English is your native language, you certainly have an
advantage in the size of your vocabulary, knowledge of grammar and
the speed at which you are able to translate complex thoughts into
words. So generally people who have English as a second language
need to put in more effort for the same quality of
communication.
That said, there are many people who have spoken and written
English for such a long time, or from such an early age on, that it
is hard to distinguish their mastery over English from that of a
native person.
