呼吸时，只需快速抬头吸气就可。低头至原位，再继续抬头吸气。

When it's time to breathe, simply lift your head quickly and grab a breath. Put your head back down, and continue.

在不呼吸的划水时不要抬头。呼吸时向前看一下，然后马上低头回到原来头身一条线的状态。

Don't lift the head at all during a non-breathing stroke, and when taking a breath, look forward, then get the head right back in line with the body.
