Question

Too much eating. Too many unhealthy foods. Too many ads for food. Too few activities. Different reasons are given for America’s weight problem---a problem increasingly shared by other countries. Almost one-fifth of American children and teenagers are overweight.

Schools have been asked to increase physical education, an important tool for public health. However, a recent study has shown an increase in the number of injuries in P.E. classes.

Researchers say one possible reason for this is a decrease in the number of school nurses. Schools without a nurse on duty may be more likely to send an injured child to a hospital.

Another possible reason for more injuries is a change in the traditional idea of physical education. This “New P.E.” expands the kinds of sports that are taught. But activities that some schools offer now, like rock climbing and skateboarding, can also increase the risks, says Cheryl Richardson, who is with the National Association for Sport and Physical Education(NASPE).

She also says not all states require P.E. teachers to be specially trained. Untrained teachers could be less likely to recognize unsafe conditions.

Cheryl Richardson points to one of the study’s findings –that injuries are often the result of contact with a person or a structure. This tells her that the teachers were not giving each student enough space to move around safely.

Six activities produced seventy percent of all injuries: running, basketball, football, volleyball, rugby and gymnastics.

The researchers say larger class sizes are another possible reason for the increase in injuries. Larger classes can mean less supervision(监督). The National Association for Sport and Physical Education says twenty to thirty students in a P.E. class should be the limit.

【解析】

试题分析：研究发现：美国学生在体育课上发生意外伤害的情况增加了。原因有很多：校医数量少，班容量大，一些危险的运动的形式的增加，学生活动空间不够，体育老师的相关培训不够都有责任。

1.C 主旨大意题。 根据文章的结果可知，第二段提到However, a recent study has shown an increase in the number of injuries in P.E. classes. 接下去就分段分析美国学生在体育课上发生意外伤害的情况增加的原因，故选C。

2.D 推理判断题。第三段介绍，学校的医护人员少，所以不得不把受伤的孩子送到医院，如果学校里有校医，那这种情况就会缓解，故选D。

3.A 细节理解题。根据文章的结果可知，第二段提到However, a recent study has shown an increase in the number of injuries in P.E. classes.学生在体育课上受伤的情况增加了，第4段说明传统的体育课变了；后面提到的班容量大，校医数量少，运动的形式多样化等说明其他选项都不正确，故选A。

4.B 细节理解题。根据第5、6段可知，有一些体育老师没有经过专业的培训，给学生的活动空间不够等导致学生受伤，和体育老师有关。故选B。
