Water is necessary for life and good health. We often forget this fact when we think about 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.
What can we conclude from this passage?
选项
A、Water is almost as important as food.
B、Many people tend to neglect the importance of water.
C、Water is the origin of life.
D、Most fruits and vegetables contain much water.
答案
B
解析
主旨大意题。本题提问的是我们能通过文章得出什么结论。通读全文可知,文章认为水分比食物更重要,所以选项A不正确;文章也没有谈及生命的起源,所以选项C也不正确;文章的主要意思也不是讨论水果和蔬菜的水分含量的,排除D。所以只有选项B为正确答案。
