1. Emotional problems: Children may feel lonely, helpless and unsafe because they are not accompanied by their parents. This may affect their emotional development, including self-esteem, self-confidence and social skills.

2. Academic problems: Children from single-parent families may face more study pressure, because they need to take on more housework and take care of young or old family members. This may affect their academic performance and future career development.

3. Behavioral problems: Children from single-parent families may show more behavioral problems, such as aggression, antisocial behavior and inattention. This may be because they lack the support and guidance of their parents, so they don't know how to handle their emotions and behaviors correctly.

4. Psychological problems: Children from single-parent families may face more psychological problems, such as depression, anxiety and inferiority. This may be because they lack the care and support of their parents, which leads them to feel lonely and lost.

In short, the influence of single-parent families on children's growth may be various, may be long-term, and may affect their lives. Therefore, society should provide more support and resources to help these children overcome difficulties and realize their potential.
