     In the opinion of many people, the two-parent family is the correct way to raise children. Traditionally,

this has been as the most natural way, but single-parent families have had to face prejudices (偏见) against

their life-style. However, the single-parent family is the fastest growing type of family. In the United States,

a national survey showed that at least 50% of children will be members of a single-parent family. So we think

it is important to throw prejudices away and to see the advantages of single-parent families.

     When compared to two-parent families,single-parent families are usually at a disadvantage in some ways.

They are often in short of money,and children receive less attention. What's more, single parents can find

themselves under too much pressure of both work and home. Despite (尽管) these disadvantages, it is

possible for single-parent families to look for support from friends, schools, communities or other organizations. They need to remember that nobody can do it alone.

     Surprisingly,single-parent families also have some advantages over two-parent families. Single parents

have greater flexibility (灵活性) in spending time with children, because they don't have to consider the needs

of a husband or wife. So they can develop closer relationships with their children. Another advantage comes

from the fact that single parents often work together with their children to solve problems, which makes

children feel more needed and valued (尊重的).

     It's important to remember that single-parent families have,until now suffered (受到) prejudices from

some people.They think that it's easier for the children in single-parent families to drop out of school in teens,

and to be jobless in their early twenties. But, with the support from friends, schools and communities,

single-parent families become more accepted by society,and this situation is certain to improve. In the future

we will probably see these prejudices disappear.
