Do you know what is the best drink in the world ?
In 21st century, there are many types of drinks.For that reason, we often ignore the most important drink - Water.
Now, in our world people are busier than before. They don't have extra engery to pay attantion on drinks.People just drink some water; however,in the real world less and less people are on attention drink pure water regularly. So , (we have investigated 28 students of 4th of ESO c.)(这什么玩意？！)
Even though some people prefer to drink other beverages,water is still a common acceptable drink for people. Everyone agrees that water is very important for the daily lives.First, 28.16% of people consider that water is indispensable, secondly 21,40% of people think it can make healthfully for their bodies, and 10.7% of people think water can stop thirsty. All of people think if they don’t drink water,they will die. A thing which make us so incredible is that even though many people know the importance of water ,they don’t drink water when they need.
Almost half of poeple drink water when they feel thirsty.In fact,this behaviour is not good for people. There is a two-thirds of water in our bodies. If you feel thirsty, you just lost 2 percent of water in your body. For example, we asked 4 students in ESO if they had a habit of dringking water when they got up, but more than half of them replied that they did not have this habit.( And this are other false custom. 什么意思？)You drink water in the morning precisely because you lose water during a time of sleeping. So, you also have to take in some fluids like water when you wake up.Other drinks cannnot do that. For instance, if you like drinking coke in the morning, it cause you high blood suger;if you like drinking coffee or juice, it doesn’t provide you enough water for digeting food. For this reason, we hope you drink water when you get up. The normal demand of water is 2 L everyday. (In this class are few people are not normal. 什么意思？不懂) The important thing we want to tell you is drinking more water can not lose weight. It only make you feel fullness. ALL in all, we can say that a three-quarter majority don’t drink water at right moment. (最后一句没看懂)
我只是从语法上改了，语言上还是有些问题（比如你主题是最好的饮料，为什么最好我没怎么看出来，例子用的不好，说服力不够。。。）
