I can only imagine. But one needs to start learning someplace.
My experience is that when learning a new languages repeated practice is the main driver of improvement. The many different kinds of exercises are valuable in they keep things more interesting while doing something with the word over and over again dozens of times or more before one really learns it.
Having done over a month now of very intense days of 4 - 8 hours a day of Germarn exercises and having just started Chinese, I'm looking for any excuse to learn by trying to really learn the language so I can count it as study time instead of just doing nothing but thousands of more exercises.
I think it would be great if someone fluent in Mandarin came along and dissected dozens of errors in that big block of unintelligible Chinese characters. I only know less than a dozen Mandarin characters so for and absolutely nothing about sentence structure. If I can't get some discussion in these forums I am doomed to do another 5 hours today of flashcards, and exercises. :-)
Do you have a small screen keyboard for entering accents in your conversation box Robert? I do not. So that's why I have to keep a side window open to Google translate, so i can put in the proper Chinese characters and accent marks. I only just discovered how to use the PinYin Look Up table keyboard in Write Up Part 2 this morning after hours of fiddling around with it.
So, here are for of my 10 Mandarin characters I actually know without Google If I'm wrong on these I will loose much face.
