So let's start with an 'F' sound where the bottom lip touches the top teeth.

从“F”音开始，下嘴唇要接触上齿。

And the 'V' sound is created by bringing the bottom lip to touch the top teeth.

‘V’的音则是需要你将上齿要出下唇而发出。

To make the V sound you gotta have contact, so the bottom lip must touch the top teeth.

要发 V 音，你必须要有接触，所以下嘴唇必须接触上牙齿。

One had silver teeth. Top row. - Okay.

有一个有银牙 顶上卷发 -好的。

It just touches behind the bottom or actually both the bottom and top teeth in the front. 'This', 'this', 'this', 'this'.

它只接触到底部后面或者实际上是前面的底部和顶部牙齿。This，this，this，this。

Right? We want to make sure that the bottom lip touches the top teeth, and then a 'TH' sound and then 'W' sound. Okay?

我们要确保下嘴唇碰到上齿，然后是‘TH’的音，接下来就是‘W’的音。

Same quality as an F or an S, but you need to create this quality of sound while the tongue is outside touching the top teeth.

和发出 F 音或 S 音一样，但是你需要在舌头伸出来接触上齿的时候发出这种音。

So, start make sure that for the 'V' and usually when you have a 'V' in the spelling, it means that you do bring the bottom lip to touch the top teeth, usually - " Very" .

所以，这个词组的开头要确保是‘V’的音，且通常情况下，如果拼写里有‘V’，就意味着在发音的时候你的下嘴唇要碰到上齿——“Very”。

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.

因此，他们不是将舌头放在上齿后面：“th”、“th”、“th”，而是将上齿放在下唇上：“f”、“f”、“f”，或：“v”、“v”、“v”，当他们说这些词时。
