When you're climbing up a hill or playing sports,your back is all wet and so is your face.Why?Because you are sweating.(36)___When your body gets hotter than that,your brain doesn't like it.It wants your body to stay cool and comfortable.So the part of your brain that controls temperature sends a message to your body,telling it to sweat.Then sweat glands(腺)in your skin start making sweat.
(37)___ When the sweat hits the air,the air makes it turn from a liquid to a vapor.As the sweat leaves off your skin,you cool down.
Sweat is a great cooling system.(38)___ Then you need to put liquid back in your body by drinking plenty of water so you won't get dehydrated(脱水的).
Sweat isn't just wet-it can be kind of stinky(恶臭的),too.(39)___It's the bacteria that live on your skin that mix with the sweat and give it a stinky smell.And when you reach puberty(青春期),special hormones affect the glands in your armpits-these glands make sweat that can really smell.Luckily,regular washing with soap and water can usually keep stinky sweat under control.
So don't worry about a little sweat-it's totally normal and everybody sweats.Sometimes too much sweating can be a sign that there is something wrong in the body,but this is rare in kids.(40)___
A.Sweat by itself doesn't smell at all.
B.When people sweat,they lose water in their body.
C.Your body works best when its temperature is about 370C.
D.The sweat leaves your skin through tiny holes called pores(毛孔).
E.The vapor goes into the air and turns into drops of water when it comes across cold.
F.But if you think you have a sweat problem,talk to your parent or your doctor about it.
G.If you're sweating a lot on a hot day or after playing hard you could be losing too much water through your skin.

答案和解析
36-40CDGAF
36.C 承上启下句.前两句通过举例子说明人体出汗这种现象,接下来的内容说明的是人体为什么要出汗,C中的Your body works best when its temperature is about 370C与下句When your body gets hotter 吻合,故选C.
37.D 主旨大意题.根据下句的When the sweat hits the air…尤其是下句的As the sweat leaves…可知,本段介绍的是汗水的挥发,故选D.
38.G 承上启下.根据下句可知,本段说的是出汗之后,应该及时补水,以免脱水.据此我们首先会想到B,但B中使用第三人称与全文使用的第二人称不符合,B不合适;C选项与上下文符合,起到承上启下的作用.
39.A 承上启下.根据首句Sweat isn't just wet-it can be kind of stinky(恶臭的),可知,主要说明汗臭的问题以及应对的方法,A中的smell与上下句及本段话题关联,故选A.
40.F 段落拓展句.根据前两句可知,本段说的是如何正确看待人体出汗问题,正常出汗不是病,当然,如果你的出汗量不正常,就应该就医,故选F.
