If you've ever thought SH, CH and J and ZH sounds are as same as or similar with SH, CH and ZH sounds in Chinese, then you are totally wrong. Because you never ever shouldn't curl your tongue when you made these sounds in English. I didn't know and I was making them in a wrong way until Coach pointed out my issue last year. But the difficulty is that if you made them in a wrong way for many years, it's extremely tough to fix. Plus, if you are so good at making SH, CH and ZH sounds in Chinese, you even couldn't notice you are curling your tongue. Even if you can notice it, It's still difficult to control your tongue. After struggling with these sounds for a month, I asked Moxa(our kind, genius student) @Moxa Xie how to make these correct English sounds, and she taught me a trick: use ji, qi, xi(Chinese) for your tongue position -- I mean when you want to pronounce SH in English, don't say SH in Chinese but start with XI in Chinese and your tongue would be straight. So, the tongue position should be-- Ji(Chinese) = J(English) Qi(Chinese) = CH(English) Xi(Chinese) = SH(English) = ZH(English) I noticed there're more and more students have these issues so I want to share this here. I hope it would help you. This trick sounds very complicated but it works for me. Of course, aware of this trick is not enough, you need to use it to train your muscle memory. And if you're not sure if you have this issue or not or you want to know more, I recommend you ask our excellent Coach-- Coach Lan. She's Chinese and she always can tell the issue. @Coach Lan ================================================================================== 如果你一直觉得,英语里的 SH、CH、J、ZH 和中文里的 sh、ch、zh 发音一样,或者至少很接近,那其实是一个很大的误区。 因为在发这些英语音的时候,舌头不应该像发中文 sh、ch、zh 那样卷起来。 我以前完全不知道这一点,也一直用错误的方法发这些音,直到去年 Coach 指出了我的问题,我才意识到。 但最难的地方是: 如果你已经这样错误地发了很多年,想改真的非常难。 而且,如果你的中文 sh、ch、zh 发得特别自然,你甚至可能根本意识不到自己在卷舌。就算意识到了,要控制舌头不要卷起来,还是很困难。
