这里是我平时用手机录的一些发音备忘。很多外国朋友在交流时，经常因为几个音的混淆闹出笑话，今天记录一下最容易踩坑的几个音。
Here are some pronunciation notes I usually record with my phone. Many foreign friends often make jokes due to the confusion of a few sounds during communication. Today, I’m recording the most common pitfalls.
易混淆点：x 和 sh
“谢谢”的“谢（xie）”，发音时嘴巴是扁的，舌尖抵住下齿背。
The “xie” in “thank you (xiexie)”, the mouth is flat, and the tip of the tongue touches the back of the lower teeth.
“是”的“是（shi）”，发音时嘴巴微突，舌尖向上卷。
The “shi” in “yes (shi)”, the mouth is slightly protruding, and the tip of the tongue rolls up.
易混淆点：ü 和 u
很多朋友会把“绿（lü）”读成“路（lu）”。
Many friends pronounce “green (lü)” as “road (lu)”.
发出“ü”音时，嘴唇要像吹口哨一样收圆收紧。
When making the “ü” sound, the lips should be rounded and tight like whistling.
一点小建议：
不要害怕发错音，本地人在真实语境中，往往能通过前后文猜出你的意思。多说、多错、多练，才是王道。
Don’t be afraid of making mistakes. Local people in real contexts can often guess your meaning from the context. Speaking more, making more mistakes, and practicing more is the key.
