Question

【题目】阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项。 People used to say that horses sweat, men perspire(流汗), and ladies glow. Now that most of us live a healthy lifestyle which includes exercise, we all sweat! The main reason our bodies produce sweat is to help us cool down. As you exercise or sit in the hot sun, your body temperature rises and your sweat glands(腺) get to work passing liquid through your skin. When your sticky sweat evaporates, it cools your skin and helps your body stay at a healthy temperature.
You may think that the sweatiest people at the gym are the ones who are out-of-shape. In fact the better shape you are in, the more you sweat! With lots of exercise heating your body regularly, your 3 million sweat glands will grow larger so they can cool you down faster. But it’s not all about exercise: genes determine how likely you are to sweat, and there isn’t much you can do to change it! On a very hot day, an average person will sweat 3 pints of liquid an hour, but someone used to the heat will sweat 8-5 pints in an hour! No wonder it’s important to drink lots and lots of water when the sun beats down．
Staying comfortable in the heat will mean sweating, but there are other ways to keep cool. Stay in the shade and dress in light colors and natural fabrics like cotton. Wear a light hat that will shade your face but will still let heat escape from your head. Drink a lot of cool liquids to rehydrate. If you are sweating a lot, you will be losing salt as well as water through your skin, so you may want a salty snack. Sweat is odorless, but the bacteria that live in it can smell bad. Keeping clean will help your friends stay friendly all summer long!

【答案】
（1）D
（2）D
（3）C
（4）B
（5）C
【解析】【文章大意】你是否曾经想过我们为什么会出汗呢？ 1从第二段 your 3 million sweat glands will grow larger so they can cool you down faster.可知汗腺的数量不会增加。
2前三项可以从文中“Stay in the shade and dress in light colors and natural fabrics like cotton.Wear a light hat that will shade your face but will still let heat escape from your head.Drink a lot of cool liquids to rehydrate.” 可知，喝水应该是为了维持水分。
3从这句genes determine how likely you are to sweat, and there isn’t much you can do to change it! 可知，爱不爱出汗是基因决定的。
4从Sweat is odorless, ...Keeping clean will help your friends stay friendly all summer long! 可知。A说法不对，由“Sweat is odorless, but the bacteria that live in it can smell bad.”这句可知。C选项也没有依据；D项根本是原文中说的。不需要推断。
5从出汗有益健康的角度可知，几个答案中只有 C项符合。
