independent and start making their own decisions．However，during this period，it can be easy for some of them to form bad habits．These bad habits，if left unchecked[1]，could lead to more serious ones when they become adults．For example，some of them may become involved in① tobacco② or alcohol③ abuse④，which can lead to physical and mental health problems[2]．To prevent harmful habits like these from dominating⑤ a teenager's life[3] is essential⑥．They must learn to recognise bad habits early and make appropriate changes． [1]“if left unchecked”为if引导的条件状语从句的省略，从句中省略了主语和be动词。 [2]“which can lead to...health problems”为which引导的非限制性定语从句，先行词是前面整个主句。 [3]动词不定式短语“To prevent...a teenager's life”作主语，看作第三人称单数形式。 To change bad habits[4] is never easy，even with many attempts．There is a famous saying based on⑦ the philosophy⑧ of Aristotle[5]：“We are what we repeatedly⑨ 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[6]．The good news is that we can change，if we understand how habits work[7]． [4]“To change bad babits”为动词不定式短语作主语，谓语动词用单数形式。 [5]“based on the philosophy of Aristotle”为过去分词短语作定语，修饰a famous saying。 [6]that引导定语从句，修饰先行词a habit。 [7]that引导表语从句，其中if引导条件状语从句。 According to modern psychology⑩，we must first learn about the “habit cycle”，which works like this： ·Firstly，there is a “cue⑪”，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 to⑫ the cue． ·Thirdly，there is the “reward⑬”，the good thing or feeling we get from the routine． For example，when we feel unhappy (cue)，we eat lots of unhealthy snacks (routine)，which makes us feel happy (reward)[8]．The reward makes us much more likely to continue the cycle，and the bad habit of relying on⑭ unhealthy snacks is formed． [8]when引导时间状语从句；which引导非限制性定语从句，先行词为前面整个主句。 To facilitate⑮ a positive change in our bad habits，we must first examine⑯ our bad habit cycles and then try to adapt them．We can do this by combining the information from our habit cycles with⑰ our own positive ideas．For example，we could try to replace a negative⑱ routine with something more positive．So，when we feel unhappy again (cue)[9]，rather than eat snacks，we could listen to some of our favourite music instead (routine)，which will make us feel relaxed (reward)[10] ．Aside from⑲ changing bad habits，we can also use the habit cycle to create good habits．For example，when we come to an escalator⑳(cue)，our normal routine is to ride it，but we could change this routine into something more positive by taking the stairs instead． [9]“when we feel unhappy again (cue)”为when引导的时间状语从句。 [10]“which will make us feel relaxed (reward)”为which引导的非限制性定语从句，先行词为前面整个主句。 Many of us try to change bad habits quickly，and if we are not successful straight away㉑，we often become pessimistic㉒ and give up．In fact，the most successful way to change is not suddenly，but over a period of time[11]．As the Chinese philosopher Laozi wrote[12]，“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 discipline㉓ and repeatedly take many small steps．After all，it is not easy to break bad habits． [11]not...but...意为“不是……而是……”，为并列连词，连接两个并列成分。 [12]“As the Chinese philosopher Laozi wrote”是as引导的非限制性定语从句，as在从句中作wrote的宾语；as意为“正如，正像”。 For young people，there is plenty of time to change bad habits．However，there is no “magic pill㉔” or delete㉕ button that will help you；you have to think about your bad habits and decide on㉖ some changes．You have the power to build a happy and healthy life full of good habits！ 健康的生活方式需养成的习惯 在成长过程中，青少年会变得越来越独立，并且开始自己做决定。然而，在这一时期，他们中的一部分人容易养成不良习惯。如果任其发展，在他们长大后，这些不良习惯可能会变得更严重。例如，有些青少年会沉溺于烟酒不能自拔，造成生理和心理健康问题。阻止这些坏习惯主宰青少年的生活是至关重要的。他们必须学会及早发现坏习惯并作出适当的改变。 即使尝试了很多次，改变坏习惯从来都不是容易的。有一条基于亚里士多德哲学思想的名言说道：“重复的行为造就了我们。”在很多方面，我们的生活方式是我们作出选择的总和。我们选择做某些事，然后我们一遍又一遍地重复。很快，这种选择就会自动形成一种难以改变的习惯。好消息是，如果我们了解习惯是如何起作用的，我们就可以作出改变。 根据现代心理学，我们必须首先了解“习惯循环”，它是这样运作的： ·第一是“触发因素”，即一个动作、事件或情况，作为做某事的信号。 ·第二是“惯常行为”，即你响应触发因素而采取的常规行动。 ·第三是“回报”，即我们从惯常行为中获得的美好事物或感受。 例如，当我们感到不高兴时(触发因素)，我们会吃很多不健康的零食(惯常行为)，这让我们感到快乐(回报)。这种回报使我们更有可能继续这一循环，依赖不健康零食的坏习惯就形成了。 想要促使不良习惯朝着积极的方向转化，我们必须首先审视自己的坏习惯循环，然后尽力去调整。我们可以通过结合自身的习惯循环信息和自己的积极想法来做到这一点。例如，我们可以尝试用一些更积极的惯常行为来代替一些消极的惯常行为。所以，当我们再次感到不高兴的时候(触发因素)，我们可以听一些我们最喜欢的音乐(惯常行为)，而不是吃零食，这会让我们感到放松(回报)。除了改变坏习惯外，我们也可以利用习惯循环来养成好习惯。例如，当我们走到自动扶梯时(触发因素)，我们的日常习惯是乘坐自动扶梯，但是我们可以通过爬楼梯把这一惯常行为变得更积极。 我们中很多人试图迅速改变不良习惯，一旦没有立刻成功，我们往往变得悲观，继而放弃。事实上，最成功的改变方式不是突然(改变)，而是要经过一段时间。正如中国哲学家老子所说：“千里之行，始于足下。”一步似乎很小，但却是至关重要的。为了达到改变的目标，一个人必须表现出一些自制力，一小步一小步地前进。毕竟，改掉坏习惯并不容易。 对于年轻人来说，有足够的时间来改变坏习惯。然而，没有“魔法药丸”或删除键可以帮助你；你必须考虑你的坏习惯，并决定作出一些改变。你有能力构建一种充满好习惯的快乐、健康的生活！ 3 / 9 学科网（北京）股份有限公司 $
