Water is necessary for life and good health. We often forget this fact when we think a-bout the other building blocks of life such as vitamins, minerals and proteins. We can live for many days without eating, but two or three days without water usually leads to death.
The human body may look solid, but most of it is water. Newborn babies are as much as 85% water. Women are about 65% water and men about 75%. Women usually have less water than men because women, in general, have more fat cells, and fat cells hold less water than other kinds of cells.
Water is necessary for cooling the body under hot weather and when we are working hard or exercising, water carries body heat to the surface of the skin, where the heat is lost through perspiration.
Researchers note that fat cells block body heat from escaping quickly. Fat cells under the skin act like warm clothing to keep body heat inside. This is why overweight people have a more easy time staying cool than thin people.
Researchers also note that cool liquids cool us faster than warm liquids, because cold liquids take up more heat inside the body and carry it away faster. They say, however, that cold sweet drinks do not work well because the sugar slows the liquid from getting into the blood stream.
The body loses water every day through perspiration and urine. If we lose too much, we will become sick. To replace what is lost, health experts say grown persons should drink about 2 liters of liquids each day, and more in hot weather. They say we can also get some of the water we need in the foods we eat. Most fruits and vegetables are more than 80% water. And even bread is about 33% water.
Why do thin people usually feel better in hot days than fat people?
选项
A、Thin people perspire less.
B、Fat people do not sweat as much as thin people do.
C、Thin people have less heat inside their bodies.
D、Fat people have more fat cells which keep the heat inside.
答案
D
解析
本题为细节推理题,提问的是为什么瘦人在炎热天气中会比胖人感觉舒服些。根据义章第四段中的描述“Fat cells under the skin act like warm clothing to keep body heat inside.This is why overweight people have a more easy time staying cool than thin people.”可以判断出,正是因为超重的人身体内更多的脂肪细胞锁住热量,才使得胖人感觉更加炎热。故答案为D)。
