i've done an essay about ”critical period hypothesis ” for one of my cource this semester. It's a idea that when human being pass a certain age, we are nearly impossible to acquire native-like pronuciation in a second language. Apparently it happens around 12-13 years old. and If you want to have a native accent , you would better to start learning before 6 years old !! It was quite shocking fact and I wish I knew this when I was little~~~ HAHAHA
Anyway, I really want to get native- llke accent in English. However, I've learnt in another lecture that accents are one of our identity! As long as it's understandable, I would believe it's doesn't matter. Accents can be different fron one country or clture to another. I had felt upset when I couldn't pronunce wors propaly before I realized this. Now i can have more confident in speaking English. I'll keep trying to get improved tho !! Keep Practicing !!
