单选题 Many young people think that their friends are the most important people in their lives. They also think their family members don"t understand them and their friends can know them. It is true that when they feel unhappy, they will go to their friends.
So it is very important for the young people to have one good friend or a group of friends. When they are not with their friends, they can also spend a lot of time talking about things on the phone. This is very important because friends can discuss everything. And these things are difficult to say to their family members.
However, parents often try to choose (选择) their children"s friends for them. If their friends are bad or don"t like studying, some parents will stop their children meeting their good friends. They think these friends may affect(影响) their children"s study. But some may let their children enjoy themselves. If bad things happen, it will be a good chance for them to learn a lesson(教训). This is another way to help children grow up.
