Running in cotton is a bad idea. Wear thin, breathable layers of synthetic ( 合成的)clothing that help protect you from the wind and snow, but still let out heat and moisture (水分) .Thirty percent of your body heat escapes through your hands and forty percent through your head. Wear a hat, or beanie (无边小便帽) ,and gloves so your circulatory system can distribute warm blood to the rest of your body.4.

【解析】

这是一篇说明文。介绍了在寒冷的天气中运动的几点注意事项，以便人们更好地运动。

1.由“Your muscles need some time to warm up when it’s cold, so take it easy when you set off and do a few stretches once you're finished.

”可知，当天气冷的时候，你的肌肉需要一些时间来热身，所以当你出发的时候要放松，当你完成的时候做一些伸展运动。这句话是对运动开始时和结束时提出的一些热身建议，所以判断出小题1也是作者对运动时提出的建议。故C选项“不要走得太快”符合句意，故C选项切题。

2.由“A belt bottle conveniently attaches to your waist so you don't have to carry it and can have a drink whenever you feel like it.”可知， 有一个腰带瓶方便地系在你的腰部，这样你就不必随身携带，只要你想喝就可以喝。所以这句话是对小题2能保证不要等到渴了再喝水的具体做法。故小题2“不要等到渴了再喝水”符合句意。故E选项切题。

3.由“Running in cotton is a bad idea. Wear thin, breathable layers of synthetic ( 合成的)clothing that help protect you from the wind and snow, but still let out heat and moisture (水分) .Thirty percent of your body heat escapes through your hands and forty percent through your head. Wear a hat, or beanie (无边小便帽) ,and gloves so your circulatory system can distribute warm blood to the rest of your body.”可知，穿棉衣服跑步不是个好主意。穿薄的，透气性的合成服装，它可以防风挡雪，但仍然能释放热量和水分。30%的身体热量通过手排出，40%通过头排出。戴上帽子，或者无边小便帽，戴上手套，这样你的循环系统就能把温暖的血液输送到你身体的其他部位。所以通过本段可以判断出小题3是本段的标题。故A选项“恰当地穿戴”符合句意。故A选项切题。

4.由小题3“恰当地穿戴”可知，除了在寒冷的冬天，穿上合试的衣服，带上帽子，还可以戴上围巾来保护自己的脸。所以小题4说的是戴上围巾来保护自己的脸。故G选项“在寒冷的日子里，戴上口罩或围巾来保护你的脸。”符合句意。故G选项切题。

5.由“you won't have the wind in your face for the second half of your run, when you are more likely to be sweating and catch a chill.”可知，但是，更重要的是，在你跑步的后半段，当你更有可能出汗和受凉的时候，你的脸上不会迎着风。所以本句具体介绍了小题5“逆风运动，顺风回家”这种做法的好处。所以F选项“逆风运动，顺风回家”符合题意。故F选项切题。
