V. Read the text and answer the questions.( 2 điểm, 0,4/ câu) WHY SHOULD YOUR FAMILY VOLUNTEER? Family Volunteer Day The first reason why many families do volunteer work is that they feel satisfied and proud. The feeling of fulfilment comes from helping the community and other people.

If that’s the case, try rethinking some of your free time as a family. You could select just one or two projects a year and make them a family tradition.
