Despite the general negative findings, it is important to remember that all children who live through a divorce do not behave in the same way. The specific behavior. depends on the child's individual personality, characteristics, age at the time of divorce, and gender. In terms of personality, when compared to those rated as relaxed and easygoing, children described as temperamental and irritable have more difficulty coping with parental divorce, as indeed they have more difficulty adapting to life change in general. Stress, such as that found in disrupted families, seems to impair the ability of temperamental children to adapt to their surroundings, the greater the amount of stress, the less well they adapt. In contrast, a moderate amount of stress may actually help an easygoing, relaxed child learn to cope with adversity.
There is some relationship between age and children's characteristic reaction to divorce. As the child grows older, the greater is the likelihood of a free expression of a variety of complex feelings, an understanding of those feelings, and a realization that the decision to divorce cannot be attributed to any one simple cause Self-blame virtually disappears after the age of 6, fear of abandonment diminishes after the age of 8, and the confusion and fear of the young child is replaced in the older child by shame, anger, and self-reflection. Gender of the child is also a factor that predicts the nature of reaction to divorce, the impact of divorce is initially greater on boys than on girls. They are more aggressive, less compliant, have greater difficulties in interpersonal relationships, and exhibit problem behaviors both at home and at school. Furthermore, the adjustment problems of boys are still noticeable even two years after the divorce.
Girls' adjustment problems are usually internalized rather than acted out, and are often resolved by the second year after the divorce. However, new problems may surface for girls as they enter adolescence and adulthood. How can the relatively greater impact of divorce on boys than on girls be explained？ The greater male aggression and noncompliance may reflect the fact that such behaviors are tolerated and even encouraged in males in our culture more than they are in females. Furthermore, boys may have a particular need for a strong male model of self-control, as well as for a strong disciplinarian parent. Finally, boys are more likely to be exposed to their parents' fights than girls are, and after the breakup, boys are less likely than girls to receive sympathy and support from mothers, teachers, or peers.

A．they care too much about the life change.
B．the great stress of their families diminishes their ability.
C．they tend to lose temper easily and are sensitive to the life change.
D．they are faced with more parents' fights than the relaxed, easygoing children.

Merchant and passenger ships are generally required to have a life preserver for every person aboard and in many cases, a certain percentage of smaller sizes for children.According to United States requirements, life preservers must design, reversible capable of being quickly adjusted to fit the uninitiated individual, and must be so designed as to support the wearer in the water in an upright or slightly backward position.
Sufficient buoyancy （浮力）to support the wearer should be retained by the life preserver after 48 hours in the water, and it should be reliable even after long period of storage.Thus it should be made of materials resistant to sunlight, gasoline, and oils, and it should be not easily set on fire.The position in which the life preserver will support a person who jumps or falls into the water is most important, as is its tendency to turn the wearer in the water from a face-down position to an upright or slightly backward position, with his face clear of the water, even when the wearer is exhausted or unconscious.
The method of adjustment to the body should be simple, and self-evident to uninitiated persons even in the dark under the confused conditions, which follow a disaster.Thus, the life preserver should be reversible that it is nearly impossible to get it on wrong.Catches, straps, and ties should be kept to a minimum.In addition, the life preserver must be adjustable to the wide variety of shapes and sizes of wearers, since this greatly affects the position of floating and the self-righting qualities.A suitable life preserver should also be comfortable to wear at all times, in and out of the water, not so heavy as to encourage to take it off on shipboard while the ship is in danger, nor so burdensome that it hinders a person in the water while trying to swim.
