Task: Text Completion
Input (English): [header] How to do an open turn in swimming [title] Swim towards the wall. [step] When you're on your last stroke of the butterfly or breaststroke, move your head to look straight down at the bottom of the pool. [substeps] Your last stroke should bring you about half a body length away from the pool wall. <sep> (A) You'll not hit the pool wall at this point. If you can also move or jump towards the wall, you're likely to land more powerfully on the water surface. (B) If you are more than half a body length from the wall, give an extra kick in the water to push yourself forward. [title] Extend your arms to reach for the wall. (C) If you use all of your body weight while swimming down the beautiful short distance, you'll trip backward and will risk losing your balance. Also remember that you are not swimming straight to the wall--you are swimming down it. (D) Practice the butterfly as close to the wall as possible without looking down at the bottom of the pool. Practicing in the reverse order of the butterfly and breaststroke can help ensure you don't miss any essential strokes while swimming around your current current group of swimmers.
