少儿英语口语启蒙,少儿英语口语：[i:]该怎么发

Video Text:

　　The [i:] sound is a front vowel, which means it feels more like it comes from here, than from here, ah. ee. To make this sound, the tongue touches the roof of the mouth, and it is a little more forward than the midpoint of the tongue, and same with the roof of the mouth. Ee. So for me, it's about that point that touches the roof of the mouth. Because the tongue is touching the roof of the mouth, the jaw cannot drop. Ee. And, as you notice, the sides of my mouth come out just a little bit. If that didn't happen, this is what it would look like: ee, ee. But they do: ee, ee.

　　[i:]是一个前元音，发这个音时舌头要触及上颚，触及点对于舌头和上颚来说都是它们中线靠前的位置。因为舌头要碰到上颚，所以下巴不能够下移。另外，嘴角一定要稍微向两侧拉伸。

　　Sample words:

　　please 请

　　ski 滑雪

　　Sample sentence:

　　She believes everything she sees. 她相信一切亲眼所见之事。
