A healthy lifestyle contains not only nutrition，healthy diets，plenty of exercise but also a good mind，mood and....　 3．What is your opinion about teenager's smoking? 　Various　. Section Ⅰ　Reading and Thinking(Ⅰ) HABITS FOR A HEALTHY LIFESTYLE As teenagers grow up，they become more independent and start making their own decisions　.[1]However，during this period，it can be easy for some of them to form bad habits　[2]．These bad habits，if left unchecked　[3]，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　[4]．To prevent harmful habits like these from dominating a teenager's life is essential　[5]．They must learn to recognise bad habits early and make appropriate changes. [1]本句是复合句。As teenagers grow up是时间状语从句；they become...decisions是主句；making their own decisions 是动名词短语作动词start的宾语。 [2]it是形式主语；for some of them to form bad habits是动词不定式复合结构，作真正的主语。 [3]if left unchecked是条件状语从句的省略，if后面省略了they are。 [4]which can lead to...problems是非限制性定语从句，which指代整个主句的内容。 [5]To prevent...life是动词不定式短语作主语。本句相当于It is essential to prevent...life。 To change bad habits　 [6]is never easy，even with many attempts.There is a famous saying based on the philosophy of Aristotle　[7]：“We are what we repeatedly do　[8]”．In many ways，our lifestyle is the sum of choices we have made　[9]．We make a choice to do something　[10]，and then we repeat it over and over again.Soon that choice becomes automatic and forms a habit that is much harder to change　[11]．The good news is that we can change，if we 　 understand how habits work.[12] [6]To change bad habits是动词不定式短语作主语。 [7]based on the philosophy of Aristotle是过去分词短语作后置定语，修饰saying。 [8]what we repeatedly do 在系动词are后面，是表语从句，what在从句中作do的宾语。 [9]we have made是定语从句，修饰先行词choices，省略了关系代词that或which。 [10]to do something是动词不定式短语作定语，修饰名词choice。 [11]that is much harder to change是定语从句，修饰先行词habit。 [12] According to modern psychology，we must first learn about the “habit cycle”，which works like this　[13]： ·Firstly，there is a“cue”，an action，event，or situation that acts as a signal to do something. 　[14] ·Secondly，there is a “routine”，the regular action you take in response to the cue.　[15] ·Thirdly，there is the “reward”，the good thing or feeling we get from the routine.　[16] [13]which works like this是非限制性定语从句，修饰先行词habit cycle。 [14]本句是复合句。there is a “cue”是句子主干，an action...situation是同位语，对cue的内容进行解释说明。that...something是定语从句，修饰前面的同位语。 [15]本句是复合句。there is a “routine”是句子主干，the regular action是同位语，you take...cue是定语从句，修饰先行词action。 [16]本句是复合句。there is the“reward”是主干，the good thing or feeling是同位语，we get from the routine是定语从句，修饰先行词thing or feeling。 For example，when we feel unhappy (cue)，we eat lots of unhealthy snacks(routine)，which makes us feel happy(reward)　[17]．The reward makes us much more likely to continue the cycle　[18]，and the bad habit of relying on unhealthy snacks is formed. [17]which makes us feel happy是非限制性定语从句；feel happy是省略to的动词不定式作宾补。 [18]本句是简单句。the reward是主语，makes是谓语，us是宾语，much more likely是宾补，to continue the cycle是动词不定式短语作状语。 To facilitate a positive change in our bad habits，we must first examine our bad habit cycles and then try to adapt them.　[19]We can do this by combining the information from our habit cycles with our own positive ideas　[20]．For example，we could try to replace a negative routine with something more positive　[21]．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)　[22]．Aside from changing bad habits　[23]，we can also use the habit cycle to create good habits　[24]．For example，when we come to an escalator (cue)，our normal routine is to ride it　[25]，but we could change this routine into something more positive by taking the stairs instead. [19]本句是简单句。动词不定式短语To facilitate...habits作目的状语，must examine和(must)try是并列谓语，to adapt them是动词不定式短语作宾语。 [20]combining...ideas是动名词短语作介词by的宾语。 [21]to replace...positive是动词不定式短语作动词try的宾语。 [22]which will make us feel relaxed是非限制性定语从句，feel relaxed是省略to的动词不定式短语作宾补。 [23]changing bad habits是动名词短语作介词from的宾语。 [24]to create good habits是动词不定式短语作目的状语。 [25]to ride it是动词不定式短语作表语。 Many of us try to change bad habits quickly　[26]，and if we are not successful straight away，we often become pessimistic and give up.In fact，the most successful way to change　 [27] is not suddenly，but over a period of time.As the Chinese philosopher Lao Zi wrote　[28]，“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　[29]，a person must show some discipline and repeatedly take many small steps.After all，it is not easy to break bad habits　[30]． [26]to change bad habits quickly是动词不定式短语作动词try的宾语。 [27]to change是动词不定式作定语，修饰名词way。 [28]As...wrote是定语从句，先行词是后面的主句内容，As在从句中作动词wrote的宾语。 [29]to reach the goal of change是动词不定式作目的状语。 [30]本句是简单句，it是形式主语，to break bad habits是动词不定式短语作真正的主语。 For young people，there is plenty of time to change bad habits　[31]．However，there is no“magic pill”or delete button that will help you　[32]；you have to think about your bad habits and decide on some changes.You have the power to build a happy and healthy life full of good habits　[33]! [31]to change bad habits是动词不定式短语作定语，修饰名词time。 [32]that will help you是定语从句，修饰先行词“magic pill”or delete button。 [33]to build a ...habits是动词不定式短语作定语，修饰名词power，full of good habits是形容词短语作定语，修饰名词life。 健康的生活习惯 随着青少年的成长，他们变得更加独立，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。这些坏习惯，如果放任不管，长大后可能会导致更严重的后果。例如，有些青少年会沉溺于烟(tobacco)酒(alcohol)而不能自拔(abuse)，造成生理(physical)和心理问题。防止像这样的有害习惯支配(dominate)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。 改变坏习惯从来都不是一件容易的事，即使尝试很多次。有一句基于亚里士多德哲学思想的名言：“重复(repeatedly)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，这种选择就变成了自动的，并形成一种较难改变的习惯。好消息是我们可以改变，如果我们了解习惯是如何运作的。 根据现代心理学(psychology)，我们必须首先了解“习惯循环”，它是这样运作的： ·首先，有一个“暗示 (cue)”，即有一个动作、 事件或情况作为做某事的信号。 ·其次，形成“惯例”，即你应对(in response to)暗示采取的有规律的行动。 ·第三，有“奖励(reward)”，即我们从惯例中得到的好东西或好感觉。 例如，当我们感到不快乐(暗示)时，我们会吃很多不健康的零食(惯例)，这让我们感到快乐(奖励)。奖励使我们更有可能继续这样的循环，依赖(rely on)不健康零食的坏习惯就形成了。 想要促使(facilitate)不良习惯朝着积极的方向转化，我们必须首先审视(examine)自己的坏习惯循环，然后尽力去调整。我们可以通过将习惯环的信息与自己的积极想法相结合来做到这一点。例如，我们可以试着用更积极的事情来代替消极的(negative)惯例。所以，当我们再次感到不开心(提示)时，别吃零食，我们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，我们还可以利用习惯循环来创造好习惯。例如，当我们遇到自动扶梯(escalator)(暗示)时，我们通常的做法是乘坐它，但我们可以通过爬楼梯来改变这种惯例，让它变成积极的事情。 我们中的许多人都试图迅速改变坏习惯，如果不能马上(straight away)成功，我们经常会变得悲观(pessimistic)并放弃。事实上，最成功的改变不是突然的，而是经过一段时间。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(discipline)，并不断小步前进。毕竟，改掉坏习惯是不容易的。 对于年轻人来说，有足够的时间来改变坏习惯。然而，没有“神奇药丸(pill)”或删除(delete)按钮可以帮助你；你必须考虑一下你的坏习惯，然后做出改变的决定(decide on)。你有能力创造一种充满良好习惯、快乐而又健康的生活！ Ⅰ.Reading for main idea. 1．What is the main idea of the text?
