Drinking water is so important for health. How much water you need in order to be a healthy human being?

Why You Need to Drink Water

Your body is estimated to be about 60 to 70 percent water. Blood is mostly water, and your muscles, lungs, and brain all contain a lot of water. Your body needs water to regulate body temperature and to provide the means for nutrients to travel to all your organs. Water also transports oxygen to your cells, removes waste, and protects your joints and organs.

Signs of Dehydration

You lose water through urination, respiration, and sweating. If you are very active, you lose more water than if you are sedentary. Thirst is an obvious sign of dehydration and in fact, you need water long before you feel thirsty.

How Much Water do You Need to Drink

A good estimate is to take your body weight in pounds and divide that number in half. That gives you the number of ounces of water per day that you need to drink. For example, if you weigh 160 pounds, you should drink at least 80 ounces of water per day. If you exercise you should drink another eight ounce glass of water for every 20 minutes you are active. If you drink alcohol, you should drink at least an equal amount of water. When you are traveling on an airplane, it is good to drink eight ounces of water for every hour you are on board plane.

Drink Enough Water

It may be difficulty to drink enough water on a busy day. Be sure you have water handy at all times by keeping a bottle for water with you when you are working, traveling, or exercising. If you get bored with plain water, add a bit of lemon or lime for a touch of flavor. There are some brands of flavored water available, but watch for extra calories.

请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入最恰当的单词。

Every year there are hundreds of earthquakes in different parts of the world. In Sept.1923, Tokyo and Yokohama were both destroyed by an earthquake and the fires that followed it. They had to be completely rebuilt. One of the most serious earthquakes was in China’s Shanxi Province in 1556. It killed almost one million people.

We measure an earthquake’s strength on the Richter scale. The Richter scale was introduced in 1935 in Southern California in the USA. It measures earthquakes on a scale of one to ten. Any earthquake measuring five or more is usually serious.

The earth’s crust (地壳) is made up of layers of rock called plates. As these plates move, they sometimes crash against each other, causing the crust to quake. In cities such as Tokyo, where small quakes happen quite often, many modern buildings are designed to be flexible so when the earth moves, they move with it.

Earthquakes can also break up gas or oil pipes. This can cause fires to break out, which can do as much damage as the earthquake itself.

Another effect of earthquakes is tsunamis (海啸). These are huge waves created by earthquakes beneath the sea. They can be many metres high and cause great damage to coastal towns and cities.

China, Japan, Russia and the USA have the highest occurrence (发生) of earthquakes in the world.
