・swim with floats
・swim with a floating ring

「用游泳圈游泳」可以用 swim with floats / swim with a floating ring 來表達。

「游泳圈」會用 floats/floating ring 來表示。

I can't swim, so when we go to the pool I always swim with a floating ring.
『我不會游泳，所以去游泳池時我總是戴著游泳圈』

I swim with floats and want to improve my swimming.
『我佩戴游泳圈，想提高游泳水平』。
