However, during this period, it can be easy for some of them to form bad habits. These bad habits, if left ________(check), could lead to more serious ones when they become adults. For example, some of them may become ________(involve） in tobacco or alcohol abuse, which can lead to physical and mental health problems. To prevent harmful habits like these________ dominating a teenager’s life is essential. They must learn to recognise bad habits early and make appropriate changes. To change bad habits is never easy, even with many________(attempt). There is a famous saying based on the philosophy of Aristotle: “We are what we________ (repeat) 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 ________(自动的） and forms a habit that is much harder to change. The good news is that we can change, if we understand how habits work. According 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 _______a signal to do something. ·Secondly, there is a “routine”, the regular action you take in response _____ the cue. ·Thirdly, there is the “reward”, the good thing or feeling we get from the routine. For example, when we feel unhappy (cue), we eat lots of unhealthy snacks (routine), _______ makes us feel happy (reward). The reward makes us much more likely to continue the cycle, and the bad habit of relying on unhealthy snacks _______(form). ________(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 ________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, ______ 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______________(悲观的） and give up. In fact, the most successful way to change is not suddenly, but over a period of time. As the Chinese philosopher Laozi wrote, “A journey of a thousand miles begins _______ 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. For young people, there is plenty of time_________(change) bad habits. However, there is no “magic pill” or delete button that will help you; you have to think about your bad habits and decide ____ some changes. You have the power to build a happy and healthy life full of good habits! 课文挖空练习二 Dear Editor, After I attended your summer camp about health and lifestyle choices, I realized I hardly ever felt well, either physically or mentally. I often felt sleepy and _____________(头晕的）, and lacked passion. Most worrying, though, I got the flu easily and experienced many toothaches, too. At the end of the camp I heard, “Change the world by changing yourself.” This_________ (stimulate) my motivation. A dentist once examined me and told me that too much sugar in my meals had damaged my teeth and health. I made up my mind to change two things in my life: to eat nothing with sugar and to exercise regularly. After that I stopped ________(buy) all the sweets, biscuits, and _________(sugar) drinks that I used to have every day. Whenever I went out with friends, I brought snacks from home, things that didn’t have any ________(add) sugar: fruit, nuts, dried meat, etc. My exercise was very simple: I went outside every day for at least 30 minutes and did something active. Sometimes I played table tennis or badminton with my cousins. Other times I jumped on my skateboard and rode around my neighbourhood, or just took a long walk. The results have been fantastic. I feel ____________(dynamic) and stronger than ever, in both body and mind. I sleep _________(sound) at night now. I no longer suffer from a flu virus or toothaches either. Best of all, in my opinion, is how I feel about myself. I feel like I’m in control of my own life. To make choices about myself is within my own power. I CAN change myself. I just need to try. Yours truly,Wang Lu Dear Editor, As I took part in the summer camp about personal life choices, I started to analyse my choices, especially what I did to relax and how it was affecting my whole life. After starting high school, I felt stressed out and always relaxed by playing computer games. I got so ________(absorb) that I played the games day and night. Playing was fun, but I felt even more ________(wear) out afterwards! So after the camp, I realised that it was very, very important to adjust my lifestyle. I decided to take control of my life and find other ways to relax. It was a big struggle not to join my friends in playing online games ______ I’m mad for them. However, I realised that to succeed_____ quitting, I had to replace it ______ something else. So I thought about what to try. Rock climbing, bowling, watching ________(comedy), and playing basketball were the things I thought of doing instead. Now my dad and I go rock climbing together_________(month)! It has enhanced the quality of my life, improving my health and increasing my happiness. I get __________(refresh) through climbing, spend more time with my dad, and get to meet new friends. After six months of trying out new ways of relaxing, I feel much more___________(energy). I feel that I can change myself for the better. And if that’s true for me, then it might truly be possible to change the world for the better. As Gandhi said, “Be the change you want to see in the world.” Sincerely, George Fielding 学科网（北京）股份有限公司 $
