答案：
I.语篇解读：本文是一篇说明文。文章主要讲了青少年的健康和运动，作者针对青少年不同的健康问题给出了一些具体的运动方案。
1.C 细节理解题。由第二段中的“Inactive” means that a persn des nt jin in many physical activities, but is nt seriusly verweight.可知，不活跃的人不是严重超重。故选C。
2.A 细节理解题。由文章第四段中的内容可知C、D是“体育锻炼是重要的”的原因。文中并没有提到体育锻炼可以让青少年长高。故选A。
3.B 细节理解题。由第四段中的Dr. Lpez suggests…stretching and bending activities. “These are really imprtant in rder t prevent injuries,” said Dr. Lpez.可知，为了避免受伤，你可以做一些伸展和弯曲活动。故选B。
I.语篇解读：本文为说明文。文章介绍了跑步对人们保持身体健康的好处。
1. lnger 句意：根据一份医学杂志中的证据报告，跑步者比非跑步者的寿命要长3年。根据题干中的than可知设空处需用副词比较级形式，故填 lnger。
2. t see 句意：你不必为了弄清跑步带来的好处而跑得很快、很久。本题考查非谓语动词。由句意可知，此处在句中作目的状语，主语yu与动词se为主动关系，故填不定式的主动式 t see。
3. dying句意：你可能饮酒、吸烟、超重，但你仍然可以通过跑步降低过早死亡的危险。本题考查非谓语动词。介词（f）后需用动名词形式作宾语，根据提示词de可知设空处填 dying。
4. is 句意：虽然经常跑步不可能使你长生不老，但报告上说与走路、骑自行车或游泳相比，跑步对延长寿命更有效。本题考查主谓一致和时态。设空处所在从句被用来介绍一种理论，需用一般现在时；再根据主语让及提示词be可知设空处填is。
5. than 根据题干中的“mre effective”可知设空处需填than，意为“比”。
6. that/which 句意：该报告的其中两名作者在2014年还发表了一项研究，这项研究表明每天只跑步5至10分钟便可以降低患心脏病或由于各种原因导致过早死亡的危险。本题考查定语从句。先行词为study，指“物”；关系词在定语从句中作主语，故填that或 which。
7. causes 本题考查名词的“数”。cause作“原因”讲时为可数名词；根据设空处前的a可知设空处填名词复数形式，故填 causes。
8. strengthen 句意：为了避免膝盖疼痛，你可以在柔软的地面上跑步、锻炼以增强你的腿部肌肉……。设空处作目的状语，需用不定式形式，故在不定式符号t后填动词原形 strengthen。
9. energetic 设空处作表语，表示主语的特征，故填形容词energetic。
10. it/running 句意：如果你时间不充裕，你只需要花费其他运动一半的时间去跑步便可获得同样的收益，因此或许我们都应该试一试跑步。设空处作give的宾语，需填名词或代词，因此用it代替上文中的 running或直接填running作宾语。
