“An apple a day keeps the doctor away.” Similarly, if we drink a little more water ever day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fibre, without giving us too much fat and sugar. But why is water important?
The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.
Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems stars as a result of dehydration—a lack(缺少) of water in the body. Most people are dehydrated (脱水)at least some of time, although they probably don’t know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty.
These doctors think that health problems such as headaches, high blood pressure and asthma could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water.
There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.

Expressions about water are almost as common as water itself. But many of the expressions using water have unpleasant meanings.

The expression “to be in hot water" is one of them. It is a very old expression. “Hot water” was used 500 years ago to mean being in trouble. One story says it got that meaning from the custom of throwing extremely hot water down on enemies attacking a castle.

That no longer happens. But we still get in “hot water”．When we are in “hot water”, we are in trouble. It can be any kind of trouble—serious or not so serious.

Being in “deep water” is almost the same as being in hot water. When you are in deep water, you are in a difficult position. Imagine a person who cannot swim being thrown in water over his head.

“To keep your head above water” is a colorful expression that means staying out of debt. A company seeks to keep its head above water during economic hard times. A man who loses his job tries to keep his head above water until he finds a new job.

“Water over the dam” is another expression about a past event. It is something that is finished. It cannot be changed. The expression comes from the idea that water that has flowed over a dam cannot be brought back again.

Bexley Middle School eighth-graders won the grand prize at the 2009 National Engineers Week Future City Competition (TM) on Feb. 18 in Washington, D.C. They competed with 37 other schools across the country.

The students qualified for the national competition by winning a regional competition on Jan. 17 in Columbus. By winning the national event, the students earned an all-expenses paid trip to Space Camp in Huntsville, Ala., according to a Bexley school district news report.

Future City aims to stir (激发) interest in science, technology, engineering and math among young people. Bexley team members were Tom Krajnak, Abby Sharp, Wyatt Peery, Elizabeth Maher, Aaron Hutchinson and Truman Haycock. They work in teams under the guidance of a teacher, Margaret Englehardt, and a volunteer engineer, Mark Sherman, design and build a city of tomorrow. Mayor John Brennan presented the students during a recent Bexley City Council meeting. Each team in the Future City competition plans its city using Sim City software and creates a model to show a physical representation of one section of the city. Team members must write both an essay about the yearly theme and an abstract about their city. They also must make a presentation to judges.

Focusing on eco-responsibility, the Bexley team built “Novo-Mondum,” an Icelandic city in the year 2171. Krajnak said the team’s project included a new water system for each resident unit and a 500-word essay on using bacteria to purify water. “We used our essay and abstract (摘要) to build a model,” he said. “It was hard to organize which building would go where, what each building does and how to make it look good.”

Englehardt said her students did a good job answering impromptu (即席) questions during the regional competition. “They can think on their feet,” she said. Principal Harley Williams said the school is very proud of the students’ performance.
