I think that we teenagers should always give a helping hand to others in need. When we help others, we also make ourselves better. We can do some charity work during summer and winter holidays. It can make our holidays colourful.
Last term, my classmate Mark had a serious blood disease. He needed an operation as quickly as possible. So we decided to donate money to him. We organized a charity show and raised money by selling things. With our support, the operation went well and he has been better. I think it's so meaningful to help others.
