Science tells us some activities are good for our health and there are some unhealthy activities. But millions of people still do those unhealthy activities. Why? what can we do to change this situation?
题目大意
科学告诉我们一些活动是健康的一些是对健康有害的。但许多人依然做一些不健康的活动。为什么？我们可以做什么可以改变这种情况？
思路解析
题目中出现名词复数“unhealthy activities”，我们不妨先思考一下指哪些活动呢，比如吸烟，酗酒，吃快餐，久坐，熬夜等，想到这些细节，我们再看原因，比如为什么吸烟酗酒呢，可能有些人缺乏自控，需要从中获取快感，再比如为什么吃快餐，我们比较容易想到快节奏社会及广告的影响；措施方面相对容易思考，一般需要政府发挥作用，比如征税或立法方面。
审题
题目属于报告类，难度不大，原因和措施可以各写两条思路， 注意题目已经给出“人们意识到某些活动是否有害”，所以如果写“人们没有健康意识”或“宣传改变这种情况”，属于不扣题观点。
提纲
写作示范
It seems that there are still a large number of people sticking to some unhealthy habits though they have known that these habits have adverse consequences. Several factors are responsible for this and some approaches can be taken to improve this situation.
It is hard for some people, especially for those who are lack of self-restraint, to change their life-damaging habits such as overdrinking and smoking. People these days live under enormous pressure, possibly due to the heavy workload and the worry of losing jobs. They regard drinking and smoking as effective ways of relieving stress and finding an escape from reality. They are unwilling to break these habits, although they are aware of the negative consequences. They believe that the enjoyment of these habits outweighs the problems.
The media also have an adverse impact on our behaviour. For example, people are likely to copy the behaviour of celebrities they see on television, including alcoholism or even drug abuse, because they regard these famous people as role models. They may choose to eat fast food, as a result of their exposure to advertisements about these foodstuffs.
Government action can improve this situation and some policies can be enforced to encourage us to modify our behaviours. Incentives can be provided to reward healthy habits, while restrictions should be imposed on some unhealthy activities. For example, some sports events can be held in communities to promote an active lifestyle. It is also likely to impose a heavy tax on alcohol, tobacco or even fatty food, so many people will consider it necessary to stay away from these habits.
In conclusion, some people find it difficult to change their lifestyles and some habits are a result of the stresses of modern life. The government has a vital role to play in ameliorating this phenomenon.
