　　Last weekend, a survey about "The feeling of happiness" was carried out among the 2,000 students of our school.

　　Sixty percent of the students feel happy with the love from their parents and relatives as well as from the warmth of families. Twenty percent think they are happy to help others, donate something to people in need or take part in a voluntary selling. Among ten percent of them think friendship gives them much delight. Apart from the above, the rest of the students describe their happiness from different aspects.

　　Based on the statistics, a conclusion can be drawn that the students have deep love for life, but their life experience is limited, so their horizons need to be broadened.
