Provide an example from your own knowledge to support your explanation. Understanding the “habit cycle” (cue，routine，reward) allows individuals to replace negative routines with positive ones.For example，if someone feels stressed (cue) and smokes (routine) to relax (reward)，they could replace smoking with deep breathing exercises (new routine) to achieve the same reward (relaxation).This way，the habit cycle is maintained，but the routine becomes healthier. Step 3　Post-reading Ⅰ.难句解构 1．These bad habits，if left unchecked，could lead to more serious ones when they become adults. [句式分析]　本句是复合句，主句是 “These bad habits could lead to more serious ones”，句子中“if left unchecked”是if引导的条件状语从句；“when they become adults”是when引导的时间状语从句。其中从句 “if left unchecked”，省略了主语和系动词。 [句意翻译]　如果任其发展，在他们长大成人后，这些不良习惯可能会导致更为严重的有害习惯。 2．The good news is that we can change，if we understand how habits work. [句式分析]　本句为复合句。句中“that we can change”为that引导的表语从句，“if we understand how habits work”为if引导的条件状语从句，句子还包含由how引导的宾语从句“how habits work”。 [句意翻译]　好消息是，如果我们了解习惯是怎么运作的，我们就可以做出改变。 3．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). [句式分析]　本句是复合句。主句是“we could listen to some of our favourite music instead(routine)”，其中“when we feel unhappy again(cue)”为when引导的时间状语从句。此外，句中使用了rather than来表示选择，即“不是吃零食，而是听音乐”。句末的“which will make us feel relaxed(reward)”是一个非限制性定语从句，修饰前面的整个主句。 [句意翻译]　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欢的音乐(惯常行为)，而不是吃零食，这会使我们感到放松(回报)。 4．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. [句式分析]　本句为复合句。句中并列连词but连接两个句子，第一个句子中主句为“our normal routine is to ride it”，“when we come to an escalator (cue)”为when引导的时间状语从句，to ride it为动词不定式短语作表语；第二个句子中by taking the stairs instead为方式状语。 [句意翻译]　例如，当我们走到电梯前的时候(触发因素)，我们的惯常行为是乘坐电梯，但是我们可以改为走楼梯，从而将这种惯常行为改为更积极的事情。 Ⅱ.写作佳句 1．句型　as引导的定语从句 教材原句　As the Chinese philosopher Laozi wrote，“A journey of a thousand miles begins with a single step.” ①众所周知，长城是中国最著名的历史遗址之一。 As is known to all，the Great Wall is one of the most famous historical sites in China. ②正如之前提到的，规律的锻炼在保持身心健康方面起着至关重要的作用。 As was mentioned earlier，regular exercise plays a crucial role in maintaining good physical and mental health. ③正如常见的情况一样，在最终采用新技术之前，人们最初会抵制改变。 As is often the case，people initially resist change before eventually adopting new technology. 学生用书第27页 ④正如许多专家所建议的，减少碳排放对于有效应对气候变化至关重要。 As many experts have suggested，reducing carbon emissions is essential to addressing climate change effectively. 2．句型　There be＋名词＋to do 教材原句　For young people，there is plenty of time to change bad habits. ①如果你保持开放的心态，总有一些新东西可以学习。 There is always something new to learn if you keep an open mind. ②如果你想在截止日期前实现目标，就没有时间可以浪费。 There is no time to waste if you want to achieve your goals before the deadline. ③没有什么比花时间陪伴家人更重要的事情了。 There is nothing more important to do than spending time with your family. Ⅲ.课文语法填空 　　As teenagers grow up，1.it is easy for some of them to form bad habits，which，if 2.left (leave)unchecked，could lead to more serious ones when they become adults.
