阅读表达。 A common concern we often hear with regard to single children is whether one child necessarily means a lonely child. Many single-child parents feel a dilemma (进退两难) associated with their decision to have only one child. There are no other children in the family for the child to associate with (交往) , and this may lead to the child feeling lonely at times, especially during vacations. Another common argument against having just one child is that an only child may be more spoiled than one with brothers or sisters. Many people believe that a single child will not have leamed to negotiate with others, and respect the give-and-take involved in many relationships. Some think this may leave the child less able to interact(交往) well with people his or her own age than one who has been raised with brothers or sisters . However,for some single-child parents, particularly those with busy careers, the pressures of giving time and energy to a second child can seem too great, resulting in them selecting to have no more children.  For other parents, the financial burden of having a second child may be the prime consideration. Still others believe that, , the parents can give, and the child can receive, more quality time and attention. This often leads to increased self-respect which, combined with increased independence, can lead to the child being more confident. 1. What is the best title of the passage?
