Read for details As teenagers grow up, they become more 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, 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 teenager’s life is essential. They must learn to recognise bad habits early and make appropriate changes. Read Para.1 to answer the question. 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，在此期间，他们中的一些人很容易养成坏习惯。这些坏习惯，如果任其发展，长大后会导致更严重的问题。例如，他们中的一些人可能参与烟草或酒精滥用，这可能导致身体和精神健康问题。防止像这样的有害习惯主宰青少年的生活是至关重要的。他们必须学会及早识别坏习惯，并做出适当的改变。 Careful--reading Read for details As teenagers grow up, they become more 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, could lead to more serious ones when they become adults.

Careful--reading By using an example 1.Why should bad teenage habits be changed? These bad habits, if left unchecked, could lead to more serious ones when they become adults. 2.How does a teenager prevent bad habits from ruling her or his life? By recognizing bad habits early and making appropriate changes. How did the author explain his idea? To 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. 2.Read Para.2 to choose the right answer. 改变坏习惯从来都不容易，即使做了很多尝试。有一句基于亚里士多德哲学的名言:“我们重复做什么，我们就是什么。”在很多方面，我们的生活方式是我们所做选择的总和。我们做出选择去做一件事，然后一遍又一遍的重复。很快，这种选择就变成了自动的，并形成了一种很难改变的习惯。好消息是，如果我们明白习惯是如何起作用的，我们就可以改变。 To 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. 2.Read Para.2 to choose the right answer. How can a choice lead to a habit? What does the word“automatic”in para.2 mean? natural B. strange C. unclear D. difficult By using quote How did the author explain his idea? make a choice repeat it automatically form a habit 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 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. For example, when we feel unhappy (cue), we eat lots of unhealthy snacks (routine), which 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 is formed. 3.Read Para.3 to finish the exercises. 根据现代心理学，我们必须首先了解“习惯周期”，它是这样工作的: 首先，有一个“线索”，一个动作，事件或情况，作为做某事的信号。 其次，有一个“常规”，即你对暗示做出反应的常规动作。 第三，是“奖励”，我们从日常生活中得到的好东西或感觉。 例如，当我们感到不开心时(暗示)，我们吃很多不健康的零食(例行公事)，这使我们感到快乐(奖励)。奖励让我们继续循环的可能性大了很多，依赖不健康零食的坏习惯也就形成了。 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 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. What are the three stages of the habit cycle? 3.Read Para.3 to finish the exercises. The cycle of how bahits are formed 01 cue 02. Routine 03 reward Scanning feel happy By using an example eat lots of unhealthy snacks For example, when we feel unhappy(cue), we eat lots of unhealthy snacks (routine), which 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 is formed. 例如，当我们感到不开心时(暗示)，我们会吃很多不健康的零食(例行公事)，这让我们感到开心(奖励)。奖励让我们继续循环的可能性大了很多，依赖不健康零食的坏习惯也就形成了. feel unhappy 01 cue 02. Routine 03 reward Which of the follow is considered as “reward ”？ A. You take a walk around the school in the morning. B. You find yourself excited after a talk with your friend. C. You decide to borrow two books from the city library. D. You're willing to volunteer in your community this weekend. cue an action, event, or situation that acts as a signal to do something. Routine the regular action you take in response to the cue. reward the good thing or feeling we get from the routine. To 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. Read Para.4 to choose answer the question. 为了促进我们坏习惯的积极改变，我们必须首先检查我们的坏习惯循环，然后尝试去适应它们。我们可以通过将我们习惯循环中的信息与我们自己的积极想法结合起来来做到这一点。例如，我们可以试着用一些更积极的东西来代替消极的习惯。因此，当我们再次感到不开心时(提示)，我们可以听一些我们喜欢的音乐，而不是吃零食(例行公事)，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，当我们来到自动扶梯(cue)时，我们通常的习惯是乘坐它，但是我们可以通过爬楼梯来改变这种习惯，使它变得更积极。 How did the author explain his idea? By using example To 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.

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. Read Para.4 to choose answer the question. What is the first step to change a bad habit? How to change a bad habit and creat good ones? What's the purpose of the two examples in the fourth paragraph? To tell us how to change bad habits by adapting bad habit cycles. 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. Read Para.5 to choose the right answer. 我们中的许多人试图快速改变坏习惯，如果我们没有立即成功，我们经常变得悲观和放弃。事实上，最成功的改变方式不是突然的，而是经过一段时间。正如中国哲学家老子所写的，“千里之行，始于足下。”一步看似很小，却是必不可少的。为了达到改变的目标，一个人必须表现出一些纪律性，并不断地迈出许多小步。毕竟，改掉坏习惯并不容易。 Many of us try to change bad habits quickly, and if we are not successful straight away, we often become pessimistic and give up.

How did the author explain his idea? By using quote From the paragraph, what are needed if we want to change a bad habit? time discipline repeated small steps all of above （细节理解题） How can a person use discipline to help change a bad habit? A person can use discipline to change a bad habit by taking many small steps to reach the goal of change. It means that we should take small steps repeatedly.

(Para. 1) Think and find 1. 省略句 (Elliptical Clause) 结构： if left unchecked 完整形式： if they are left unchecked 解析： 这是一个由 if 引导的条件状语从句。 当从句的主语（they）和主句的主语（These bad habits）一致，且从句中含有 be 动词（are）时，可以省略从句的主语和 be 动词。 left unchecked 是过去分词短语作状语，表示“如果不加控制/放任不管”。 2. 被动语态 (Passive Voice) 结构： are formed / be left 解析： left 在这里是动词 leave 的过去分词，意为“使……处于某种状态”。left unchecked 字面意思是“被置之不理”，在句中作条件状语。 Think and find 3. 固定搭配 (Fixed Phrases) lead to 含义： 导致，引起。 语法： 后面接名词、代词或动名词（V-ing）。 例句： This mistake may lead to failure.（这个错误可能导致失败。） more serious ones 含义： 更严重的一些（习惯）。 语法： ones 在这里指代前面提到的复数名词 habits，避免重复。more serious 是形容词比较级。 Think and find 4. 时间状语从句 (Adverbial Clause of Time) 结构： when they become adults 解析： when 引导时间状语从句，表示“当……时候”。注意主句用的是过去将来时（could lead），从句用了一般过去时（became），这是符合时态逻辑的。 Think and find There is a famous saying based on the philosophy of Aristotle: “We are what we repeatedly do.” (Para. 2) 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。” 1. 过去分词短语作后置定语 这是本句中一个非常地道的修饰手法。 结构： a famous saying **based on** the philosophy of Aristotle 解析： 这里的 based on 是过去分词短语，用来修饰前面的名词 saying（谚语）。 它相当于一个省略了的关系从句：which is based on... 含义： 表示“基于……（亚里士多德哲学）的”。 Think and find 2. 表语从句 这是这句话的核心亮点，也是亚里士多德名言的精髓所在。 结构： We are **what we repeatedly do**. 解析： what 引导了一个表语从句（Predicative Clause）。 语法功能： what 在从句中充当动词 do 的宾语，同时连接主句和从句。 直译逻辑： 我们是我们反复做的事情（的总和）。 意译： 我们（的本质）就是我们反复做的事情。 Think and find 3. 副词修饰动词 结构： repeatedly do 解析： repeatedly 是副词，由形容词 repeated 加 -ly 变化而来。 它修饰动词 do，表示“重复地、再三地”。 Think and find 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). (Para. 4) 因此，当我们再次感到不高兴时（触发因素），我们可以听几首自己最喜爱的音乐（惯常行为），而不是吃零食，这会使我们感到放松（回报）。 这句话是一个非常典型的复合句，包含了条件状语、介词短语对比以及非限制性定语从句。以下是详细的语法知识点解析： 1. 时间状语从句 (Adverbial Clause of Time) 结构： when we feel unhappy again (cue) 功能： 由 when 引导，修饰主句的谓语动词（could listen），表示动作发生的时间。 注意： 这里的 (cue) 是插入语，用来解释说明前面整个从句在“习惯循环”中的角色（提示/触发因素）。 Think and find 2. 介词短语对比结构 (Prepositional Phrase for Comparison) 这句话中有一组非常地道的对比结构，用于表达“取舍”： 结构： rather than + 名词/动名词 (这里是 rather than eat snacks) 含义： “而不是……”。 语法细节： rather than 后面通常接动词原形（在并列结构中）或动名词。这里与后面的 instead 呼应，加强了对比语气。 副词： instead 位置： 放在句末或句首。 含义： “相反”。 搭配： ...we could listen to music **instead**.（我们可以听音乐来代替吃零食。） Think and find 3. 情态动词 + 动词原形 结构： we could listen ... 功能： could 是情态动词，表示可能性或建议（在这里指一种可行的替代方案），后面必须接动词原形 listen。 4. 非限制性定语从句 (Non-restrictive Attributive Clause) 这是本句中语法层级最高的部分。 结构： ..., which will make us feel relaxed ... 引导词： which。这里 which 指代前面整个主句的内容（即“听音乐”这个行为），而不是单指“音乐”。 功能： 对前面提到的行为进行补充说明，解释其带来的结果或好处（即“奖励/回报”）。 标点： 逗号 , 不能省略，这是非限制性定语从句的标志。 Think and find 5. 使役动词结构 结构： make us feel relaxed 句型： make + 宾语 + 宾语补足语。 us 是宾语。 feel relaxed 是省略了 to 的不定式作宾语补足语（在使役动词 make 后，跟 do）。 📝 句子成分拆解 为了方便理解，我们可以把句子拆开看： 条件： When we feel unhappy again, （当……时候） 对比： rather than eat snacks, （而不是吃零食） 主干： we could listen to music instead, （我们可以听音乐来代替） 结果/补充： which will make us feel relaxed. （这会让我们感到放松） Think and find As the Chinese philosopher Lao Zi wrote, “ A journey of a thousand miles begins with a single step.” (Para 5) As 引导的非限制性定语从句 结构： As the Chinese philosopher Lao Zi wrote, 功能： As 在这里引导一个非限制性定语从句，指代后面整个主句（即引用的名言）的内容。 含义： “正如……那样”。它在句首引出依据或来源，相当于“正如中国哲学家老子所写的那样”。 正如中国哲学家老子所说：“千里之行，始于足下。” Think and find As the Chinese philosopher Lao Zi wrote, “ A journey of a thousand miles begins with a single step.” (Para 5) (1) 学校广播宣布，运动会将于下月举行。 (2) 正如我所指出的，日常饮食包含蔬菜很重要。 As is announced on the school radio, the sports meet will be held next month. As I have pointed out, it is important to include vegetables in our diet. 正如中国哲学家老子所说：“千里之行，始于足下。” Translate Reading and Thinking 新人教选择性必修三 Unit 2 Thank You ! 06 2 Read the text and find out what main ideas 人民教育电子音像出版社 普通高中教科书 英语 选择性必修 第三册 264795.16 $
