根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 Habits for a healthy lifestyle As teenagers grow up, they become more independent and start making their own decisions. However, during this period, it can be easy for some of them to form bad habits, such as tobacco or alcohol abuse. To prevent harmful habits like these from dominating teenagers, life is essential. . We are what we repeatedly do. In many ways, our lifestyle is the sum of choices we have made.  According to modem psychology, we must first learn about the "habit cycle":  Firstly, there is a "cue"(触发因素), an action, event, or situation that acts as a signal to do something. Secondly, there is a "routine ", the regular action you take in response to the cue. Thirdly, there is the "reward", the good thing or feeling we get from the routine. For example, when feeling unhappy (cue), we eat lots of unhealthy snacks (routine), which makes us feel happy (reward).  Gradually, the bad habit of relying on unhealthy snacks is formed. To reach a positive change in our bad habits is also possible.  We can do this by combining the information from our habit cycles with our own positive ideas. Aside from changing bad habits, we can also use the habit cycle to create good habits. For example, when we come to an escalator (cue), our normal routine is to ride it, but we could change this routine into something more positive by taking the stairs instead. Many of us try to change bad habits quickly, and if we are not successful straight away, we often become pessimistic and give up.  To reach the goal of change, a person must show some discipline and repeatedly take many small steps. After all, it is not easy to break bad habits. A. However, there exists some "magic pill" that will help you. B. However, we can change if we understand how habits work. C. The reward makes us much more likely to continue the cycle. D. We must refer to all sorts of information about different snacks. E. We must first examine our bad habit cycles and then try to improve them. F. They must learn to recognize bad habits early and make appropriate changes. G. In fact, the most successful way to change is not suddenly, but over a period of time. 答案：【1】F【2】B【3】C【4】E【5】G
