在完全前够并且没有沉肘的时候，感觉好像你把你手指点到了一只枪管的前段（再收一点手腕），这就是抓水的开始。

At full reach and without dropping your elbow, feel like you are tipping your finger-tips over the front of a barrel (again flexing at the wrist), which will start the catch.

讽刺的是，沉腕和沉肘是抓水里最大的敌人。

Ironically, dropping the wrist and elbow is one of the worst things you can do for your catch.

作为一个规律，初级和中级选手都会有不好的抓水技术，有沉肘，沉腕的手部姿势，很少有曲肘的。

As a rule, beginner and intermediate swimmers have very poor catches with dropped elbows, dropped wrist hand positions and very little elbow bend.
