【答案解析】[参考范文1]
Some countries are experiencing a situation where their citizens are becoming heavier and also less fit and healthy. The causes of this are clear, but there are many possible solutions. I shall look at the causes and a couple of possible solutions in this essay.
In almost all cases, the causes of increased weight are diet and/or lack of exercise. If a person eats more calories than they use, they gain weight. If they do not exercise enough, this weight gain will be fat and too much fat causes health problems. The solutions, therefore, are simple enough-convince people to consume fewer calories and/or exercise more.
This is easier said than done. Nowadays, more and more people have access to more and more food. Many people prefer food that is high in calories-perhaps because they think it tastes better or perhaps because it is faster or more convenient. One way of getting them to eat fewer calories might be to show them tastier dishes quickly prepared using lower calorie foods.
Another solution is to get people to exercise more, so that eating more calories is less of a problem. This could be done by making keeping fit less costly and easier to participate in. Financing sports and exercise facilities could be costly, but there could be long term savings if people are healthier as a result. If neighbourhoods had sports and exercise facilities, people would be able to use them more often.
In conclusion, there are two main causes of weight increase and there are several possible solutions to this and to declining levels of health and fitness.

In this essay, I shall look at why the average weight of people in some countries is increasing at the same time that their health and fitness is decreasing.
The reasons why people increase in weight are well known-higher calorie intake and less exercise. In turn, these factors cause people to become less fit and healthy. People may be eating more because they have more high-calorie food available. Less exercise may be due to the increased use of cars and less participation in sports and exercise activities. Whatever the reasons, many countries where the average weight of citizens is increasing are looking for solutions.
Some nutritionists have suggested that processed foods are particularly likely to cause people to gain weight. To encourage people to eat less of this kind of food, perhaps the government could increase tax on it. This should encourage people to eat cheaper, healthier alternatives. This kind of thing is already done in most countries with two other things that are considered unhealthy-tobacco and alcohol.
Another possibility is to have a campaign to get people to exercise more. It may be possible to use famous people and various forms of media to do this-the Internet, television, radio, billboards and flyers. The idea is that if people are given more information about healthy lifestyles, they will be more likely to take notice and follow the suggestions.
To summarise, the causes of this problem are clear. The possible solutions to declining levels of health and fitness are numerous and depend on decision-makers.
