跑出更好的自己！
跑出更好的自己！


Running is one of the best exercises for your body and mind. It is easy to start and you do not need any special equipment. All you need is a pair of comfortable shoes!

First, running is good exercise for your heart. When you run, your heart works harder to move blood around your body. This can keep your heart healthy. A healthy heart helps build a healthy body.
Second, running can help you feel good. After a run, your body generates chemicals that improve your mood. That is why many people say they feel relaxed and less worried after a good run. Running is a great way to clear your mind!
Third, running can help you sleep better. Physical activity during the day can make your body feel tired, so you can fall asleep more easily at night. 
So why not put on your shoes and go for a run today? Even a short run can do a lot of good for your health.

1.1.What do you need for running?

A A pair of nice shoes.

B A sports teacher.

C A good friend.

D A big park.

解析：选A。A细节理解题。根据第一段最后一句“All you need is a pair of comfortable shoes!”，说明跑步唯一需要的就是一双舒适的鞋。不选B、C、D，原文未提及跑步需要老师、同伴和公园，均为无关信息。故选A。

2.2.What happens to your heart when you run?

A It beats faster.

B It takes a rest.

C It gets smaller.

D It moves to legs.

解析：选A。A细节理解题。根据第二段“your heart works harder to move blood around your body”，心脏更努力地工作，这意味着心跳会加快。不选B、C、D，文中没有心脏休息、变小、转移到腿部的描述。故选A。

3.3.The word “generates” in Paragraph 3 means ______.

A 储存

B 消耗

C 产生

D 阻止

解析：选C。C词义猜测题。根据第三段“your body generates special chemicals that improve your mood”，再从逻辑上推理：跑步后身体怎样了化学物质，才能改善心情？必然是“产生”或“生成”化学物质。C 项最符合语境。不选A、B、D，储存、消耗、阻止都无法和 “改善情绪” 形成通顺逻辑。故选C。

4.4.What can we learn from Paragraph 4?

A Running makes it hard to sleep.

B Being active during the day helps sleep.

C Students should sleep less than adults.

D Sleeping well takes a lot of time.

解析：选B。B推理判断题。 第四段说“Physical activity during the day can make your body feel tired, so you can fall asleep more easily”，即白天的身体活动能让身体感到疲惫，从而更容易入睡。由此可推断，白天保持活跃有助于睡眠。不选A和原文意思相反；C、D段落完全没有相关内容。故选B。

5.5.What is the passage about?

A How to run fast.

B The good ways to run.

C Running is good for us.

D The best place for running.

解析：选C。C主旨大意题。统观全文：第二段讲跑步对心脏好（good for heart），第三段讲跑步能改善心情（improve mood），第四段讲跑步帮助睡眠（sleep well），最后一段总结说跑步对健康大有好处（do a lot of good）。全文没有讲跑步技巧、没有比较其他运动、没有指定跑步地点——它始终围绕“跑步的好处”展开。C项是对全文最准确的综合概括。不选A、B、D，文章没有讲解跑步技巧、跑步地点，仅介绍益处。故选C。
