[原文呈现]HABITS FOR A HEALTHY LIFESTYLEAs teenagers grw up, they becme mre independent and start making their wn decisins.Hwever, during this perid, it can be easy fr sme f them t frm bad habits.These bad habits, if left unchecked, culd lead t mre serius nes when they becme adults.[1] Fr example, sme f them may becme invlved in① tbacc② r alchl③ abuse④， which can lead t physical and mental health prblems.T prevent harmful habits like these frm dminating⑤ a teenager's life is essential⑥.[2] They must learn t recgnise bad habits early and make apprpriate changes.[1]if 引导的句子为省略句，补全为： if they are left unchecked，在句中作插入语， when 引导时间状语从句。[2]句中动词不定式作主语。
T change bad habits is never easy, even with many attempts.[3] There is a famus saying based n⑦ the philsphy⑧ f Aristtle: “We are what we repeatedly d.” In many ways, ur lifestyle is the sum f chices we have made.We make a chice t d smething, and then we repeat it ver and ver again.Sn that chice becmes autmatic and frms a habit that is much harder t change.[4] The gd news is that we can change, if we understand hw habits wrk.[5][3]句中动词不定式作主语。[4]句中第二个that引导定语从句。[5]句中that引导表语从句，其中if引导条件状语从句。
Accrding t mdern psychlgy⑨， we must first learn abut the “habit cycle”， which wrks like this：·Firstly, there is a “cue⑩”， an actin, event, r situatin that acts as a signal t d smething.·Secndly, there is a “rutine”， the regular actin yu take in respnse t⑪ the cue.·Thirdly, there is the “reward⑫”， the gd thing r feeling we get frm the rutine.Fr example, when we feel unhappy (cue), we eat lts f unhealthy snacks (rutine), which makes us feel happy(reward)．[6] The reward makes us much mre likely t cntinue the cycle, and the bad habit f relying n⑬ unhealthy snacks is frmed.[6]句中when引导时间状语从句， which引导非限制性定语从句。
T facilitate⑭ a psitive change in ur bad habits, we must first examine⑮ ur bad habit cycles and then try t adapt them.We can d this by cmbining the infrmatin frm ur habit cycles with⑯ ur wn psitive ideas.Fr example, we culd try t replace a negative⑰ rutine with smething mre psitive.S, when we feel unhappy again (cue), rather than eat snacks, we culd listen t sme f ur favurite music instead (rutine), which will make us feel relaxed(reward)．[7] Aside frm⑱ changing bad habits, we can als use the habit cycle t create gd habits.Fr example, when we cme t an escalatr⑲ (cue), ur nrmal rutine is t ride it, but we culd change this rutine int smething mre psitive by taking the stairs instead.[7]句中when引导时间状语从句， which引导非限制性定语从句。
Many f us try t change bad habits quickly, and if we are nt successful straight away⑳， we ften becme pessimistic21 and give up.In fact, the mst successful way t change is nt suddenly, but ver a perid f time.As the Chinese philspher La Zi wrte, “A jurney f a thusand miles begins with a single step.”One step seems small, but it is essential.T reach the gal f change, a persn must shw sme discipline22 and repeatedly23 take many small steps.After all, it is nt easy t break bad habits.Fr yung peple, there is plenty f time t change bad habits.Hwever, there is n “magic pill24” r delete buttn that will help yu；yu have t think abut yur bad habits and decide n25 sme changes.Yu have the pwer t build a happy and healthy life full f gd habits！
[课文翻译]健康的生活习惯随着青少年的成长，他们变得更加独立，并开始自己做决定。然而，在这段时间里，他们中的一些人很容易养成坏习惯。如果放任不管，在他们成年后这些坏习惯可能会导致更严重的后果。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。防止像这样的坏习惯支配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，并做出适当的改变。
改变坏习惯绝非易事，即使有很多次的尝试。有一条基于亚里士多德哲学思想的著名谚语说道：“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做出的选择的总和。我们选择做某事，然后我们一遍又一遍地重复它。很快，这种选择就变成了无意识的，并形成一种较难改变的习惯。好消息是如果我们了解习惯是如何运作的，我们就可以改变。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，有一个“暗示”，即有一个动作、事件或情况作为做某事的信号。第二，形成“惯例”，即你根据暗示采取的有规律的行动。第三，有“奖励”，即我们从惯例中得到的好处或感觉。
例如，当我们感到不快乐(暗示)时，我们会吃许多不健康的零食(惯例)，这让我们感到快乐(奖励)。奖励使我们更有可能继续进行这样的循环，继而养成了依赖不健康零食的坏习惯。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。我们可以将习惯循环的信息与自己的积极想法结合来做到这一点。例如，我们可以试着用更积极的事情来代替消极的惯例。所以，当我们再次感到不快乐(暗示)时，不要吃零食，而是可以听一些我们最喜欢的音乐(惯例)来代替，这将使我们感到放松(奖励)。除了改变坏习惯以外，我们还可以利用习惯循环来塑造好习惯。例如，当我们遇到自动扶梯(暗示)时，我们通常的做法是乘坐自动扶梯，但我们可以通过走楼梯来改变这种惯例，使之变为更积极的事情。
我们中的许多人都试图迅速改变坏习惯，如果不能马上取得成功，我们经常会变得悲观然后放弃。事实上，最成功的改变方式不是一蹴而就的，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。”一步看起来很小，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定的自制力，并不断小步前进。毕竟，改掉坏习惯并非易事。对于年轻人来说，有足够的时间来改变坏习惯。然而，没有可以帮助你的“神奇药丸”或删除按钮；你必须考虑一下你的坏习惯并决定做出一些改变。你有能力创造一个充满良好习惯、快乐而又健康的生活！
