Following is the introduction of a person.
... He has taught at high schools, colleges, and private language schools, all age groups and levels. He has been training teachers for 5 years, and has presented teaching workshops.
Is there anyone who can explain the difference if "has been training" is substituted with "has trained", in terms of "feeling"? IMHO, I think the meanings would be same.
Thanks in advance. :)
