1.It’s easy for teenagers to form bad habits which have negative impacts on their physical and mental health， so preventing harmful habits is important. As the saying goes， "We are what we repeatedly do，" which is indicated in the concept of "habit cycle" in modern psychology. Then how does the "habit cycle" work？ Firstly， there is a "cue" as a signal. Then there is a "routine" in response to the cue. Finally， there is the "reward"， the good thing we get from the routine stimulating another repetition of the cycle. To facilitate a positive change to bad habits， we must examine our bad habit cycles，decide on what changes will be made and try to adjust them. Remember not to be pessimistic if you don’t succeed straight away. After all， there is no "magic pill" or delete button！
2.I got so absorbed in mobile games before， another addictive thing other than alcohol and cigarettes according to specialists， that I often felt dizzy and worn out since I also had to keep up with my schoolwork. Therefore， I made up my mind to change and refresh myself then. First， I arranged the time used on my mobile phone reasonably， instead of relying on my parents to enhance my discipline. Second， I turned to different activities in spare time， like skateboarding， bowling， swimming， and watching comedies， since a healthy life is composed of many parts. With the liberation from mobile games， a dynamic student has come back.
