Then we have " ree" , an r sound and a high e.

然后是“ree”，一个/r/音和一个高/e/音。

What happens to your REE — this is this middle line here, that's the resting energy expenditure.

REE 会如何变化呢——就是这条中的线，它就是静息能量消耗。

We have an ax! Ree! Ree! Ree!

我们有这个证据 斧子！

And if this is too hard, just try to make the " ree" sound without the ending.

如果这太难了， 就试着发出没有结尾的“ree” 声。

So this is saying: " dee" and " ree" ; the " d" sound and the " r" sound.

所以这是说：“dee” 和“ree” ； “d” 音和“r” 音。
