Correct or Incorrect?
Why is this given as a correct Chinese sentence:
But when I use it in an exercise the same exact sentence is counted wrong:
They use 就 in their own sentence, but using 就 in my answer was counted wrong. I don't understand.
I'm chinese(grew up in England but I go to a chinese school) so i don't really bother will learning it, I was just wasting time on Duolingo. It's hard to explain, but you can never translate chinese to english word to word.If we translate your chinese sentence to english then it would be- If you cannot come then you must tell us. The 就 is not needed. Google translate is not helpful as they translate the words wrong.And what did you translate the chinese sentence to? Then i can help you more. :)
If that is what you have done, i believe that Duolingo is wrong, but we can't complain too much as it is a free website.When i was doing the placement test, it did say some of my answers were wrong when they were correct. If it's really bugging you, you could of reported that problem or just complain to the Duolingo support.:)
