I have had many difficulties since I started to learn English. Since I come from the south of China, I can not distinguish nasal sounds from non-nasals: they sound exactly the same in my dialect.
Thus, I had a hard time telling “night” from “light” at the very beginning. My poor memory also added to the difficulties when I decided to enlarge my vocabulary. English words were so elusive that I could only remember them for a while.
I have spared no efforts to overcome the difficulties and finally succeeded. In order to tell the slight difference between nasal sounds and non-nasals, I forced myself to speak mandarin everyday.
Whenever I started to speak English, I reminded myself the difference between “night” and “light”.
At first I felt it rather unnatural, but as I went on I was gradually accustomed to speaking in this way.
As for my wretched memory, I gave up mechanical memorization and tried many other new ways.
At last I found a most efficient way for me: memorizing English words by their stems and affixes. This is how I have overcome some difficulties in learning English.
