英语教练 Stefanie So, instead of putting the tongue behind the top teeth for: " th" , " th" , " th" , they're just putting their top teeth on their bottom lip: " f" , " f" , " f" , or: " v" , " v" , " v" when they say those words.
所以,他们不说“th”,“th”,“th”时把舌头放在上牙后面,而是把上牙放在下唇上:“f”,“f”,“f”,或
在说那些词时发出:“v”,“v”,“v”。
