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

然“ree”，个/r/音和个高/e/音。

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

REE 水平会如何变化呢——就这条中的线，它就静息能量消耗。

We have an ax! Ree! Ree! Ree!

我们有这个证据 ！

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.

所以这说：“dee” 和“ree” ； “d” 音和“r” 音。
