　　以下是笔者给出的一个参考答案：
　　choose: older children take care
　　题型：利弊分析类
　　话题： 家庭教育类，生活类
　　1. Culturally, older children have been entrusted with the role of the care-taker in a family of more than one child. This is because they are often told to take care of their little brothers or sisters by their parents. Adding that they see their parents in the same way, it is plainly easy for them to identify themselves as parents. For example, girls usually like to tell stories to their younger brothers and sisters, or feed them when their mothers are busy with housework. Boys are like superheroes protecting their flesh and blood from any potential danger. So under certain circumstances, older children are good helpers in nurturing.
　　2. Furthermore, learning to nurture their younger family can help them better prepare for their adult life. Today, many children are spoiled and self-centered. Some of them are even indifferent to others. Consequently, they will have hard time socializing with others in future. In this respect, they are supposed to be taught how to be a responsible citizen. Even though they have very limited abilities in terms of taking care of others, this can make them more responsible and more thoughtful people. So this practice provides them an opportunity to grow up, not only grow old.
　　3. Finally, older children also can enhance family relationship. Many working women have trouble keeping a healthy balance between their family and their work. They often complain about their husbands and have been sick and tired of endless housework and baby-sitting. In this situation, older children can be a good helper in a family, who can reduce their mothers’ workload by doing some small things, making a better family atmosphere. This is definitely a positive way to keep family members stay together. Moreover, they will harvest good relationship with their younger brothers and sisters.
