easy for some of them to form bad habits.These bad habits,if left unchecked,could lead to more serious ones when they become adults.For example,some of them may become involved in tobacco or alcohol abuse,which can lead to physical and mental health problems.To prevent harmful habits like these from dominating a teenagers life is essential.They must learn to recognize bad habits early and make appropriate changes.Q1:Why should bad teenage habits be changed?Raise the problem（细节理解题）（细节理解题）Detailed reading Para.2To change bad habits is never easy,even with many attempts.There is a famous saying based on the philosophy of Aristotle:“We are what we repeatedly do.”In many ways,our lifestyle is the sum of choices we have made.We make a choice to do something,and then we repeat it over and over again.Soon that choice becomes automatic and forms a habit that is much harder to change.The good news is that we can change,if we understand how habits work.Q2:How can a choice lead to a habit?Analyze the problem Para.3According to modern psychology,we must first learn about the“habit cycle”,which works like this:Firstly,there is a“cue”,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.Q2:What are the three stages of habit cycle?The three stages of the habit cycle are the cue,routine,and reward.Para.4To facilitate a positive change in our bad habits,we must first examine our bad habit cycles and then try to adapt them.We can do this by combining the information from our habit cycles with our own positive ideas.For example,we could try to replace a negative routine with something more positive.So,when we feel unhappy again(cue),rather than eat snacks,we could listen to some of our favourite music instead(routine),which will make us feel relaxed(reward).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.Q3.Solve the problemhabit cycleRoutineovereatinghabit cycleRoutinelisten to music cuesadcue sadRewardhappyReward happy Para.5 Many of us try to change bad habits quickly,and if we are not successful straight away,we often become pessimistic and give up.In fact,the most successful way to change is not suddenly,but over a period of time.As the Chinese philosopher Lao Zi wrote,“A journey of a thousand miles begins with a single step.”One step seems small,but it is essential.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.Q4.What else are needed if we want to change a bad habit?A.time B.discipline C.repeated small steps D.all of above Solve
