居然会用儿化音这么厉害

What a coincidence. I often meet the similar problem with using foreign language. Easier reading than writing. When sometimes I get started to write, it is hard to memorise those idiomatic wording, appropriate structure, grammatical rules.

我3年前去过维也纳，的确是个很美的城市！加油！

Hey Carl, and thank you for the comment ! as I tried to explain, i am trying to avoid using words and grammar that I haven't learned yet, because i am only writing this to prepare for my exams, by using grammar rules that we have practiced. like 因为...所以， 不但..而且，来/去， 虽然...但是，了，着，and so on. It is easy when I read it in the textbook, but when using it in my own sentences it becomes a bit more complex! so therefore this text is, as I said, a bit simple in the language - because I am only in my 1st year, and I don't want to confuse myself too much! =) It takes some time to understand the usage of the grammar rules, and to feel comfortable by using them, so that is why I am rewriting back and forth, to see if i get it. I believe that some of my sentences seem very weird because I am trying to write something that is actually more complex than what we have learned, so I am using the grammar in the "wrong" way, because I should actually use grammar that I havent learned yet?! Like I said, i still think in norwegian/english when I build sentences, and that is something that I have to change, because chinese is so different. my sentences get ruined when i think like that, but surely that will change as I get better and learn more (hopefully)! I am going to look at the corrections again, and see if i can write something else, that is more correct =)
