阅读短文，根据其内容回答问题。

         Some children are born bosses (领导，指挥者). They have a need to make decision, manage their

environment and lead rather than follow. Too much rule in the hands of the young isn't healthy for children

or the family. Family expert John Taylor says, "Children have secret feelings of weakness. They are always

trying to feel safe." It's the parents' duty-not the child's -to provide safety.

        When a "boss child" doesn't learn limits (限制) at home, troubles will appear outside the family. The

child may have trouble obeying (服从) teachers, for example, or keeping friends. It can be pretty lonely as

the top dog if no one likes your ruling ways.

        Bossy kids are often unusually bright. Their parents need to be especially careful to manage them.

Bossy kids usually work more on the mother. It's important for both parents to know their child's weakness,

to agree on key rules and to back each up.

        Even as you try to be kind-to a point-don't give up your parental ruling post. Instead, stand your ground

by using body language that tells your child who the boss is.

        Good manners (礼貌) are important to family. Show a child by example how to ask for something rather

than shout orders. Try asking your child to do things that are not too difficult. Then reward (奖励) him with

a hug (拥抱) and words such as "Thank you. I like it when you listen to me." Over time good manners will

become associated (联系) with pleasure.
