Translating English into Chinese is so difficult

My English teacher asked my friends and me I to translate a passage about Paris.  We did not know Pairs Paris  know the place very well.  ,and Some of the sentences are very hard for us. It took us about three hours.  Now I feel very tired.But I but also feel happy because from the group work teamwork, I have learnt many things. We disscused the difficult points together and chose the best answer.  Group Working as a team is a good way to study. I like it. 

You need to leave NO space before the period or comma and then 2 spaces and 1 space respectively.  If you don't know see the rules, see the the following link.  I am surprised that your teacher did not teach you well.

Also try not to repeat the same word twice in a short span of time in your essay.  It makes your piece as if written by a child unless you are trying to make a point.  I don't see you trying to that here.
