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. 改变坏习惯从来都不是一件容易的事，即使经过多次尝试。以亚里士多德的哲学为基础，有一句名言:“我们反复做什么，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。我们选择做某件事，然后一遍又一遍地重复。很快，这种选择就会自然而然地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，我们可以改变。 P3 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 ①the cue. Thirdly, there is the “reward②”, the good thing or feeling we get from the routine. 根据现代心理学，我们必须首先了解“习惯周期”，它的工作原理是这样的: 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“惯例”，你在回应提示时采取的常规行动。 第三，有“奖励”，我们从日常生活中得到的好东西或感觉。 5. …there is a “routine”, the regular action you take in response to the cue. 形成“惯例”，即你根据暗示采取的有规律的行动。 in response to: sth that is said or written or done as a reply or reaction to sth 回答；答复；反应；响应 eg The product was developed in response to customers’ request. 【拓展】 ▲ make response to 对……作出响应/答复 eg They have made generous response to the appeals for funds. 他们对募集资金的呼吁作出了慷慨的响应。 ▲ make no response to 不回答、不回应…… eg After this statement, we’ll make no response to divorce matters. 在此声明之后，我们将不会对离婚事宜做出任何回答。 6. …there is the “reward”, the good thing or feeling we get from the routine. 有“奖励”，即我们从惯例中得到的好东西或好感觉。 ①reward n. something that you get because you have done something good or helpful or have worked hard 回报；奖励；报酬 give/ offer a reward to sb. for sth. in reward for eg I send him a book in reward for his timely help. ②reward v. to give something to someone because they have done something good or helpful or have worked for it 奖励;奖赏；给以报酬 为某事而给某人奖励 作为（对）……的奖赏、回报 ▲ reward sb. with sth. eg “Thank you, son,” she said, and she rewarded him with a coin. “谢谢你，好心人。”老妇人说着,而且她送了一枚钱币给他。 ▲ reward sb. for (doing) sth. eg He gave the children some chocolate to reward them for behaving 1) Make the extra effort to impress the buyer and you will ____________ (reward) with a quicker sale at a better price. 2) He decided to give a reward ____ information leading to the recovery of the missing diamond. 3) The girl rewarded him _____ a smile for his help. be rewarded for with 奖赏某人某物 为（做）某事奖赏某人 P4 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 on① unhealthy snacks is formed. 例如，当我们感到不开心时(提示)，我们会吃很多不健康的零食(常规)，这会让我们感到快乐(奖励)。奖励使我们更有可能继续这个循环，并且形成了依赖不健康零食的坏习惯 7. …, and the bad habit of relying on unhealthy snacks is formed. rely on: to depend on;to put trust in with confidence rely on sb./ sth. to do sth. rely on it that… (rely on后面跟从句时，先接it再接that。) eg Children tend to rely on concerned school friends to keep in touch with school work. You may rely on it that he will come to meet you. 1) 许多职业母亲依靠亲戚来帮她们照看孩子。 Many working mothers rely on relatives to help take care of their children. 2) 我仅能依靠的是他能告诉我事实真相。 I only rely on it that he can tell me the fact. 依靠或信赖某人/ 某物做某事 相信……, 指望…… P5 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. 为了促进坏习惯的积极改变，我们必须首先检查我们的坏习惯循环，然后尝试适应它们。我们可以通过将我们的习惯周期信息与我们自己的积极想法相结合来做到这一点。例如，我们可以尝试用一些更积极的事情来取代消极的日常生活。 So, when we feel unhappy again (cue), rather than ①eat 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. 所以，当我们再次感到不开心时(提示)，我们可以听一些我们最喜欢的音乐来代替吃零食(常规)，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周期来养成好习惯。例如，当我们来到自动扶梯(提示)时，我们通常的习惯是乘坐它，但我们可以通过爬楼梯来改变这种习惯，让它变得更积极。 (1) She’d rather die than _____ (lose) the children. (2) He is an explorer rather than a ______ (sail). (3) You rather than I _____ (be) going to go camping. (4) The sweater she bought was beautiful rather than ______ (cheaply). (5) She enjoys singing rather than ________ (dance). (6) We will have the meeting in the classroom rather than ____ the great hall. (7) I decide to write rather than ______________ (telephone). (8) He came running rather than __________ (walk) 8. 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）。 lose sailor are cheap dancing in (to) telephone walking 19 It was the culture, rather than the language, that made it hard for him to adapt to the new environment abroad. rather than 后接不定式时，不定式可以带 to，也可以不带 to。但当rather than 位于句首时，则只能接不带 to 的不定式。 rather than 连接的并列成分可以是名词、代词、形容词、介词短语、动名词、分词、不定式及动词等。rather than 连接两个名词或代词作主语时，谓语动词应与 rather than 前面的名词或代词在人称和数上保持一致。 Practice Driverless cars may end up being a form of public transport ____________ (而不是) vehicles you own, says Ryan Calo at Stanford University, California. She likes keeping things rather than to throw them away. （改错） 是文化而不是语言使他难以适应国外的新环境。 (强调句) rather than throwing 20 P6 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, but① over a period of time. As the Chinese philosopher Lao Zi wrote②,“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. 我们中的许多人都试图迅速改变坏习惯，如果我们不能立即成功，我们往往会变得悲观并放弃。事实上，最成功的改变方式不是突然，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。”一步看似很小，但却是必不可少的。为了达到改变的目标，一个人必须表现出一定的纪律，并不断地采取许多小步骤。毕竟，坏习惯是不容易改掉的。 11. In fact, the most successful way to change is not suddenly, but over a period of time. ▲这是一个含有“not…but…”结构的简单句。 ▲句中的不定式短语to change作定语，修饰way。 Translate the sentences into Chinese. The value of life lies not in the length of days, but in the use that we make of them. 生命的价值不在于其长短，而在于我们如何利用它。 My teacher influenced my decision to study science. 我的老师对我学理科的决定起了影响作用。 11. 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 23 P7 For young people, there is plenty of time to change bad habits.
