"テニスでは中毒者が硬い長方形の中を動き回り、修正された雪の靴で毛羽立ったボールを待ち伏せしようとする。"

Simplified Meaning:

Imagine someone really obsessed with playing tennis. They spend a lot of time running back and forth on a rectangle-shaped court. The goal of this game is to try and hit a fluffy ball, making it fly to the other side in a way that's hard for their opponent to hit back. They use a racket, which is kind of like a special tool that looks like a snow-shoe but is designed for hitting the ball instead of snow. In tennis, you're always trying to outsmart your opponent by hitting the ball in a way they don't expect. Picture a cat trying to catch a laser pointer—it's a fun mix of strategy and quick movements. Someone who loves tennis can’t wait to get back on the court, just like someone working hard to achieve something they love. You can use this passion and commitment in any part of your life, whether it’s learning a new skill, working on a project, or even playing another sport. Keep focused, make clever moves, and you'll get better and better at whatever you love to do.
