All parents know that one of their most important tasks is to prepare their children for an independent life，but any parent can tell you that it’s hard to let go of your children．That balance between keeping your children safe and allowing them to learn from their own mistakes can be heartbreaking．Years of experience means that parents often do know best，but on the other hand，the young，being less bound by tradition，are often more creative，more able to find new solutions to old problems．Revolutions are led by the young．

Good teachers make the growth of critical （批判性的） thinking easier in their students，only to find that this can lead to a questioning of the teachers’ basic beliefs．Schools encourage parents to become involved，but are often embarrassed when parents have reservations about some of the educational methods being used．Governments encourage unimportant groups to empower themselves in order to participate fully in the development process．And they are often surprised when the new leaders of these groups turn around and attack the policies of that same government．The rebellions （叛逆的）young and the newly unimportant groups are important in social development．They are not necessarily representatives of those they want to represent or not realistic in their demands，but their voices must be heard．

Good parents know that just forbidding particular behaviors does not prevent their children from finding ways to engage in these forbidden activities．Indeed，sometimes the forbidden fruit is more inviting，just because it is not accepted by authority．Parents must work with their children to educate them on the facts，know as much as possible about he lives of their children，provide a good example，encourage more wholesome activities but also support their children when they don’t follow what is expected of them．But the most important point is that they also need to learn how to let go．

Dogs are social animals and without proper training, they will behave like wild animals. They will soil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing. The key to preventing or treating behavior problems is learning to teach the dog to redirect its normal behavior to outlets that are acceptable in the domestic setting.

　　One of the best things you can do for your dog and yourself is to train its obedience. Obedience training doesn’t solve all behavior problems, but it is the foundation for solving just about any problem. Training opens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do.

Training is also an easy way to establish the social rank order. When your dog obeys a simple request of “come here, sit,” it is showing obedience and respect for you. It is not necessary to establish yourself as top dog or leader of the pack（群）by using extreme measure. You can teach your dog its subordinate（从属的）role by teaching it to show submission to you. Most dogs love performing tricks for you to

pleasantly accept that you are in charge.

　　Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and can more safely be allowed a greater amount of freedom than an untrained animal.
