Question

【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
How Fit Are Young Teens?
How often do you exercise? A new study finds that most kids ages 12 to 15 aren't getting enough physical activity.
U.S. fitness guidelines recommend (推荐) an hour or more of physical activity every day. According to the study, only 1 in 4 U.S. kids meet the recommendation. Few kids in the survey met the guidelines for physical activity that raises the heart rate and makes you breathe harder. However, most of those kids said they did at least an hour of exercise at that level during the previous week.
The study found fat teens were less active than normal-weight girls and boys. Overweight girls were slightly less active than normal-weight girls.
“There's always room for improvement,” said health expert Tala.She also said the results provide useful information to help with fitness campaigns such as Let's Move, which was launched by First Lady Michelle Obama. To inspire kids to eat right and get in shape, the First Lady visits schools and holds exercise events. She also calls on schools to offer regular gym classes.
The research suggests kids who get physical education may get better grades.
A. It's concerning.
B. She is an expert on children's health.
C. She was the lead author of the study.
D. The results are based on about 800 kids.
E. Schools should give kids more time for physical activity.
F. But levels were similar among overweight and normal-weight boys.
G. Overall, about 25% said they got an hour of that kind of difficult exercise every day.

（2）考查对上下文的理解和推理判断能力。这一段都是讲根据美国健康参考标准，美国孩子实际的锻炼情况，只有G项符合这一内容。故选G。
（3）考查对上下文的理解和推理判断能力。根据空前”Overweight girls were slightly less active than normal-weight girls.“过重的女孩稍微不如体重正常的女孩活跃，此处选择F. But levels were similar among overweight and normal-weight boys.“但是过重的男孩的活跃程度和体重正常的男孩类似”呼应上文。
（4）考查对上下文的理解和推理判断能力。与上文语境中提到的“health expert Tala”相呼应，此处选择B. She is an expert on children's health.“她是青少年健康方面的专家”。
（5）考查对上下文的理解和推理判断能力。上文提到研究表明受过体育教育的孩子可能会有更好的学习成绩，此处选择E. Schools should give kids more time for physical activity.“学校应该给予孩子们更多锻炼时间”呼应上文。
