Last week, I, along with the rest of my grade, went on a 18-hour survival training trip. When we arrived in, we put up our tents before making lunch. Then we participated in team-building activity such as dragon boat racing or rock climbing. They were all extremely fun yet tiring. The most excited event was the boat racing, as I have never been in a dragon boat before. The thrilling feeling of riding over the waves will stay my mind forever. By the end of the day, they were all sweaty and exhausted. We packed up the next morning, take back with us our new created memories.

About how to keep healthy, I’d like to offer my advices. As we know, we teenagers are going through a rapid growth which needs to be support by a healthy and balanced diet. Thus, we need a variety of food but cut out the food rich in sugar or fat. However, we should take physical exercise regular. For example, we can play basketball or take walk after school. Have enough sleep is of great importance. Therefore, you should have at least eight hours of sleep every day and not stayed up too late. Only in this way that can we keep fit.
