英文可以點寫?

你想的自由自在一般可從free to/of或being free這個字開始構思，亦可以用freedom to...，不過這些free字都會聯想到自由(政治上或者是心境上)，所以如果你的意思是活動上的感覺，而不是意識上的感覺，則要加上一些附助的詞語。

如果用以上的構思，我會寫成

I like swimming because it gives me the sense of freedom when I am in the water.

I enjoy swimming as you can imagine the freedom and fun when you are in the pool.

I like swimming because I enjoy....

I like swimming because I like the feeling of freedom into the surface water ..

I like swimming because I enjoy being free in the water.
