Answer 1

#1 -- I'd use "in" rather than "at."

#2 -- Do you mean "...written emails in English"?

#3 is fine.

#4 -- should be "Home Plus" if "Plus" is part of the store's name.

#5 -- again, I'd use "in" rather than "at."

#s 6, 7, 9, and 10 are fine.

#8 -- "online" instead of "on line."

Overall, there are very few errors! Good for you!!
