這堂課使我想起我在大學時修過的英語語音學，我在課堂上學過無窮多關於发音、重读、韻律(节奏 is also good )的規則及例外。(I may translate like this.)

大部分人觉得学习中文很难，当然是。但是(I may prefer 然而= however)，如果你(想)要深度学习语言，所有的语言都很复杂，都有很多特点。从语言学的角度的来说，并不存在 "难的语言" 的说法，你覺得難(I may add this to make the sentence more smooth.)是由于你的母语格式化(I may prefer 固化)了你语言的能干力和思考的方式(or 模式, both are good.). It's the mothertongue that formats our language abilities and thinking patterns. 

最难的地方其实是deconstruct 母语强加固有的框架 and 建立新的合适你在学习的语言.
The difficulty actually is not in the language itself but in the ability to deconstruct the constraints imposed by our mothertongue and build a new one to fit the language you want to learn

困難的(最难的 is also fine but stress the idea of "the most difficult".)地方並非語言本身，而是在於解構(=deconstruct)母語加(強加 is also ok but more tense word.)於我們身上的框架，並且建立一個新的適合你在學習的語言的架構。

以后有这样的机会请告诉我 (for them to let me know of any similar opportunities in the future)

(I am not sure what you want to express exactly. However, I guess you may mean that please let you know if there are  any opportunity like that you took the class this time in the future.)未來如果有類似這樣上課的機會，請告訴我。

我这几天上了普通话课，每次的3个小时都感覺很快就过了。
I had the opportunity to go to a putonghua class these past days.
