[写作点评 ] A Camping in Summer
A Camping in Summer
I just got back from camping with my mom and sister and we had a really good time. I wouldn’t have imagined that spending a whole week in the wilderness would be fun, but it was. Walking on the rural roads, telling fairy tales and swimming in the lake —what more could you want I think my favorite part about going camping is just sitting in the absolute peace and quiet and reading a good book. It’s so hard to find time to be alone when you’re at home, so I love it when I get to just relax in the bush with nothing but the sounds of birds and the water washing onto the shore. It is a little depressing now that our trip is over, because in a week, I’ll go to school. I’ve never really been afraid of going back to school, but this summer has just been so enjoyable, and I don’t want it to end! And once school starts, I am going to try my best to study hard, so I must do some preparations for that.
Notes:1. absolute adj.完全的2. depressing adj.令人郁闷的
