Nowadays more and more people are concerned about their health. But how to keep healthy? Different people may give different answers to this question. In my opinion, it is essential to do the following.

现在越来越多的人关心健康。但是如何保持健康呢？对于这个问题，不同的人可能给出不同的答案。在我看来，必须做到以下几点。

First, it is absolutely necessary to take some exercise every day. Research shows that getting plenty of exercise make the heart beat faster and the lungs work harder. This strengthens the heart， reduces the chance of heart attack， and helps lower blood pressure. That's why more and more people are becoming active in various kinds of sports and exercises. Second, it has been proved by medical researchers that what people eat affects their health. They advise people to eat more fruit and vegetables and less meat such as beef and pork because meat contains more fat than poultry and fish. Fat can build up in the arteries, block the flow of blood, and cause a heart attack or stroke.

首先，每天锻炼身体是绝对必要的。研究表明，进行大量运动会使心跳加快，肺部工作更努力。这可以增强心脏动力，减少心脏病发作的机会，并有助于降血压。这就是为什么越来越多的人积极参加各种运动和锻炼。第二，医学研究人员已经证明，吃什么会影响健康。他们建议人们多吃水果和蔬菜，少吃牛肉和猪肉等肉类，因为肉类比家禽和鱼类含有更多的脂肪。脂肪会在动脉中积聚，阻碍血液流动，导致心脏病发作或中风。

If people follow these two ways of keeping fit, they greatly improve their health.

如果人们遵循这两种保持健康的方法，他们的健康状况会大大改善。
