n/l不分:
1. Begin with a L：
1) Mouth should be wide open and jaw should be down（don’t move your jaw along with your tongue);
2)Tongue should rise up and push behind your top teeth;
3)Drop and relax your tongue.

2. L in the middle(focus on the L sound and push it out)：
inflation, believe, volume, glue, elevator, solve, pulling, flood, delete, elect, alive, color...
3. L at the end of a word:
1) the L sound comes from the movement of the tongue slowly rising;
2)your jaw should keep down and should not be moving at all;
3) don’t close your mouth.
hill, will, ball, tall, call, small, control, powerful, financial, people
4. FL blends:
A flea and a fly, flew up in a flue.
Said the flea, “Let us fly!”
Said the fly, “Let us flee!”
So they flew through a flaw in the flue.

可能的原因：元音ee和i发音我也振动了鼻腔,需要练习元音而不是L音。
