Exercise 5: Read the following passage and mark the letter A, B, c, or D on your answer sheet to indicate the correct word or phrase that best fits each of the numbered blanks. We first learn about loving and caring relationships from our families. Family is defined as a domestic group of people with some degree of kinship - whether through blood, marriage, or adoption. Ideally, each child is nurtured, respected, and grows up to care for others and develop strong andhealthy relationships. This does not mean that it is always easy to make and keep friends; it just means that we share the goal of having strongrelationships. "Family" includes your siblings and parents, as well as relatives who you may not interact with every day, such as your cousins, aunts, uncles, grandparents, and stepparents. These are probably the people you are closest to and with whom you spend the most time. Having healthy relationships with your family members is both important and difficult. Families in the 21stcentury come in all shapes and sizes: traditional, single parent, blended (more than one family together in the same house), and gay and lesbian parents - just to name a few. No matter the "type" of family you have, there are going to be highs and lows - good times and bad. Many times, however, families become blocked in their relationships by hurt, anger, mistrust, and confusion. These are natural and normal, and few families do not have at least a few experiences with them. The worst time for most families, is during a divorce. By making a few simple changes in the way we look at the world and deal with other people, it is possible to create happier, more stable relationships. Families need to be units of mutual caring and support; they can be sources of lifelong strength for allindividuals.
