I am correcting a short journal writes up from my student, who is from Korea and notice that I am so lacking of grammar knowledge in explaining to her why it is wrong in her sentence.
Below is one of her work:
"Today, some teachers who are from a University in Canada came to our school to give an introduction talk about their University."
This is the opening of her journal. For me, I think it sounds not very right. Below is my correction:
"Today, some of the lecturers, who are from a University in Canada visited our school to give an introduction talk about their University."
What do you think of my correction?
And after you have answered the above question, can you give me some tips on how to correct students' essay? Shall I change their whole sentence? Or I just change their grammar mistake?
