14 My Leisure-Time Activity

When I have free time, I usually go mountain climbing alone.

The mountain where I go all the time isn't very high or rugged; therefore, it only takes me about half an hour to reach the top.

The surround-ing scenery is very charming.

It's no doubt the best place to view the rough sea.

Moreover, when in high spirits, I'll sing several folk songs.

Sometimes I'll bring a novel with me and do some leisure reading.

After climbing the mountain, I'll be exhausted, but soon I'll feel energetic again because of the fresh air at the top of the mountain.

What's more, it makes me forget all my worries.

As mountain climbing is so much fun, it's really worthwhile doing this healthful activity on a regular basis.
