英文小作文：

My Favorite SwimStroke

I love swimming because it allows me to clear my mind and focus on nothing but the movement of my body in the water. My favorite stroke is butterfly because it requires a combination of strength, technique, and endurance. It"s a challenging stroke to master, but once I"ve got it down, I feel like I"ve achieved something great.

When I"m swimming butterfly, I focus on my kicks and pulls. I push my legs down hard, then pull my arms back with power. This rhythm helps me to keep my body straight and my strokes smooth, which in turn helps me to swim faster.

Butterfly is also a great way to work on my endurance because it requires me to keep going for longer periods of time than other strokes. It"s not easy, but the feeling of accomplishment when I finally master the stroke is worth every bit of effort.

Overall, swimming butterfly is a great way to exercise and stay healthy, but it"s also a great way to clear my mind and focus on the present moment. I love how it challenges me, but also how it brings me joy and satisfaction at the end of each session.
