内容简介：Join the New York Times bestselling authoron a journey to the sun-washed hills of TuscanyDr. Isabel Favor, author of Four Cornerstones for a Favorable Life , has sacrificed everything to build her self-help empire. Then, in a matter of weeks, it all comes crashing down. Broke, heartsick, and soul-weary, she heads for Italy in search of a little breathing room. Lorenzo Gage makes his living killing people on the silver screen, that is. He's viciously handsome and sublimely talented. But as he begins his vacation in Italy, he's also vaguely dissatisfied. Being a villain with a face to die for has its rewards, but he hates the feeling that everything he's neglected in life is catching up with him. Then he spots Isabel sipping a glass of wine at a sidewalk cafÉ. A good guy wouldn't think of seducing such a tidy-looking woman... but he'd never seen the fun in playing the hero. Breathing Room is a book for any woman who's ever dreamed of wandering through a vineyard, of lazing under the Tuscan sky, or of reforming a deliciously wicked man. Because sometimes it takes a special place... a special love... a little breathing room... for life to deliver all its glorious promise.

托福阅读原文
【1】Of all the physiological differences in human sleep compared with wakefulness that have been discovered in the last decade, changes in respiratory control are most dramatic. Not only are there differences in the level of the functioning of respiratory systems, there are even changes in how they function. Movements of the rib cage for breathing are reduced during sleep, making the contractions of the diaphragm more important. Yet because of the physics of lying down, the stomach applies weight against the diaphragm and makes it more difficult for the diaphragm to do its job. However, there are many other changes that affect respiration when asleep.
【2】During wakefulness, breathing is controlled by two interacting systems. The first is an automatic, metabolic system whose control is centered in the brain stem. It subconsciously adjusts breathing rate and depth in order to regulate the levels of carbon dioxide (CO2) and oxygen (O2), and the acid-base ratio in the blood. The second system is the voluntary, behavioral system. Its control center is based in the forebrain, and it regulates breathing for use in speech, singing, sighing, and so on. It is capable of ignoring or overriding the automatic, metabolic system and produces an irregular pattern of breathing.
【3】During NREM (the phase of sleep in which there is no rapid eye movement) breathing becomes deeper and more regular, but there is also a decrease in the breathing rate, resulting in less air being exchanged overall. This occurs because during NREM sleep the automatic, metabolic system has exclusive control over breathing and the body uses less oxygen and produces less carbon dioxide. Also, during sleep the automatic metabolic system is less responsive to carbon dioxide levels and oxygen levels in the blood. Two things result from these changes in breathing control that occur during sleep. First, there may be a brief cessation or reduction of breathing when falling asleep as the sleeper waxes and wanes between sleep and wakefulness and their differing control mechani *** s. Second, once sleep is fully obtained, there is an increase of carbon dioxide and a decrease of oxygen in the blood that persists during NREM.
【4】But that is not all that changes. During all phases of sleep, several changes in the air passages have been observed. It takes twice as much effort to breathe during sleep because of greater resistance to airflow in the airways and changes in the efficiency of the muscles used for breathing. Some of the muscles that help keep the upper airway open when breathing tend to become more relaxed during sleep, especially during REM (the phase of sleep in which there is rapid eye movement). Without this muscular action, inhaling is like sucking air out of a balloon—the narrow passages tend to collapse. Also there is a regular cycle of change in resistance between the two sides of the nose. If something blocks the "good" side, such as congestion from allergies or a cold, then resistance increases dramatically. Coupled with these factors is the loss of the complex interactions among the muscles that can change the route of airflow from nose to mouth.
【5】Other respiratory regulating mechani *** s apparently cease functioning during sleep. For example, during wakefulness there is an immediate, automatic, adaptive increase in breathing effort when inhaling is made more difficult (such as breathing through a restrictive face mask). This reflexive adjustment is totally absent during NREM sleep. Only after several inadequate breaths under such conditions, resulting in the considerable elevation of carbon dioxide and reduction of oxygen in the blood, is breathing effort adjusted. Finally, the coughing reflex in reaction to irritants in the airway produces not a cough during sleep but a cessation of breathing. If the irritation is severe enough, a sleeping person will arouse, clear the airway, then resume breathing and likely return to sleep.
【6】Additional breathing changes occur during REM sleep that are even more dramatic than the changes that occur during NREM. The amount of air exchanged is even lower in REM than NREM because, although breathing is more rapid in REM,it is also more irregular, with brief episodes of shallow breathing or absence of breathing. In addition, breathing during REM depends much more on the action of the diaphragm and much less on rib cage action.

托福 阅读答案
1.以diaphragm做关键词定位至第三句和第四句，说ribcage运动变少，使得diaphragm更重要，但stomach的压力使得diaphragm工作起来更困难，B是正确答案。A的increased movement of the rib cage和C的需要pressure都与原文相反;D说diaphragm contributes to原文没有说。
2.EXCEPT题，排除法。A的centered in brain stem做关键词定位至之一句，但原文说这个特点是属于automatic，metabolic system的，而voluntary的center是在forebrain，所以A错，选;B的a number of activities做关键词定位至倒数第二句的一大堆活动，所以B正确，不选;C的bypass the automatic system和D的irregular breathing pattern做关键词都定位至最后一句，都正确，不选。
3.exclusive仅有，只有，排他，所以正确答案是sole。从单词本身看，include→exclude→exclusive，所以一定能得出排他之意。原句说在NREM期间，automatic系统怎么控制breathing，使得氧的需求量减少，前面一直在说两个系统，现在氧的需求量减少了，肯定是有系统不干活了，所以就是只有automatic在干活，所以答案是D只有。A持续、B完美，都不靠谱，C的partial刚好与原文意思相反，也不选。
4.此题关键词难找，可以顺序向下看，也可以用排除法，如果顺序向下看的话，会看到之一点说的是当sleeper在睡与醒之间摇摆的时候，发生了呼吸cessation，也就是stop，所以正确答案是B，stop for a short time。C和D一个说氧上升一个说二氧化碳下降，是一回事，都不是在睡觉期间发生的，所以都反了，而且两个一样的也都不选，A没说。
5.修辞目的题，先看修辞点所在的 句子 ，但原句整个都是一个例子，往前看。前一句仍然在说肌肉relax的事情，因此也是例子，所以看开头，开头说air passage在睡觉期间变了很多紧接着就解释睡觉期间呼吸很难，也就是开头所指的变化是睡觉的时候呼吸变难，所以正确答案是C。A的refute与原文相反;B的比较和D的prevent blockage原文都没说。
6.EXCEPT题，排除法。A的relaxation of the muscles做关键词定位至第三句，正确，不选;B的two sides of the nose做关键词定位至倒数第三句，正确，不选;C的upper airway做关键词定位至第三句，但答案的easier airflow原文完全没说，C错，选;D的complex muscle interaction做关键词都定位至最后一句，正确，不选。
7.以inhaling is difficult做关键词定位至第二句，但这句只说了difficult的事儿，没说发生了什么，往下看。下句说NREM期间什么adjustment都没有，只有在inadequate breaths之后才adjust，所以答案是B。A是wakeful时候才有的;C的因果关系原文没说;D完全没说。
8.以irritation做关键词定位至最后一句，说如果irritation太严重，睡着的人就会醒，按照正常的叙述顺序应该是先叙述mild的情况，前一句果然在说coughing reflex没产生cough，而产生了cessation of breathing，呼吸停止的状况，所以答案是D。C与原文相反;B是severe的时候才有的，A没说。
9.considerable可观的，相当的，重要的，所以正确答案是significant。从单词本身看，consider的考虑的意思是很常见的，加形容词词尾able变为值得考虑的，所以也是significant。原文说在若干次inadequate breaths之后，二氧化碳含量怎么上升氧气含量下降，才能调整breathing，一般我们说显著的变化，所以答案A，其他答案都不靠谱。
10.resume重新开始，再继续，所以正确答案是restart。原句说如果irritation太严重了，睡着的人会醒来，清理呼吸道，并且怎么呼吸，前一句都说了因为irritants呼吸停止，然后醒来，当然清理完就继续呼吸了呗，答案是D。A和B完全不靠谱，如果选C，之前应该adjust一次，但之前从来没说irritation严重的时候有先调整一次，所以C错。
11.原句的结构是exchange lower是因为blabla，所以正确答案是A，因果关系和结构都正确。其他答案都没提到exchange lower这个主干，而且B把原文非主干的部分变成了主干;C结果搞乱;D逻辑关系错。
12.两个过渡点，名词respiration和连词however。根据respiration可以初步确定答案是B或者C，但根据however断定B不对，因为两个however不能连续出现，所以正确答案是C。
13.之一段和第二段在讲wakeful部分，其余在讲sleep部分。The role选项对应之一段第三句，属于wakeful部分。Carbon dioxide选项对应第五段第四句，二氧化碳多氧少，属于sleep部分。The coughing选项原文没说reflex复杂，不属于任何一列，不选。A great deal选项对应原文第四段第三句，属于sleep部分。Upper airways选项原文没说，不选。There is选项对应原文第六段第二句，属于sleep部分。Automatic选项对应原文第二段首句，属于wakeful部分。
托福阅读译文
【1】关于人类睡觉和清醒时生理状态的差异在过去的十年里已被发现，在所有的这些差异中，呼吸系统控制方面的变化尤其引人注目。不仅是呼吸系统运作水平有差异，在如何运作方面也出现了变化。胸腔所做的呼吸运动在睡觉时会减少，使得横膈膜的收缩变得更为重要。然而由于躺下来的物理作用，胃部压迫横膈膜使得横膈膜难以工作。不管怎样，睡眠时还有很多其他的变化影响着呼吸。
【2】清醒的时候，呼吸受到两个互相影响的系统的控制。之一个是自动的新陈代谢系统，它的控制中心在脑干。它会潜意识的调整呼吸频率和深度来控制二氧化碳和氧气的浓度以及血液中的酸碱比。第二套系统是自发行为系统。它的控制中心在前脑，调节说话、 唱歌 、叹息等行为时的呼吸。它能忽略或无视自动新陈代谢系统并且产生无规律的呼吸模式。
【3】在NMER(睡觉时没有快速眼部活动的阶段)这个阶段中，呼吸会变得更深更有规律，但是呼吸频率会降低，导致总体空气交换减少。发生这个是因为在NREM睡眠阶段中，自动的新陈代谢系统会独自控制呼吸，身体会利用更少的氧气产生更少的二氧化碳。同时，自动的新陈代谢系统对血液中二氧化碳和氧气的含量反应并不灵敏。在睡眠中呼吸控制的变化会导致两个结果。之一，睡着时呼吸可能会有短暂的停止或减少，因为睡眠者在睡眠和清醒之间徘徊，而这两种状态的控制系统不一样。第二，一旦得到了充足的睡眠，血液中二氧化碳含量升高而氧气含量降低，在NREM阶段也会持续这样。
【4】但这并不是全部的变化。在睡眠的所有阶段中，气道的一些变化已经被观察到了。睡眠时需要付出两倍的努力去呼吸，因为呼吸道气流的阻力会比较强并且用来呼吸的肌肉的效率会有变化。一些在呼吸时帮助保持上呼吸道通畅的肌肉在睡觉的时候会变得松弛，特别是在REM阶段(就是有快速眼部运动的睡眠阶段)。没有这种肌肉运动，呼吸空气就像从气球里吸气一样，狭窄的通道会面临崩溃。而且鼻子两侧的阻力也会周期性改变。如果有时候堵塞了“好”的一边，比如过敏和感冒引起的堵塞，阻力就会大大增加。与这些因素一起的是那些能够改变从鼻子到嘴巴的气流路径的肌肉之间失去了复杂的交互。
【5】其他呼吸调节机制在睡眠时显然要停止运作。比如说，在清醒时如果呼吸变得困难的话就会有一个立即自动适应性的呼吸增强(比如戴上面具呼吸)。但在NREM状态时完全不存在这样反射性的调节。在这种情况下，只有几次不充分的呼吸后使得血液中二氧化碳的含量显著提升以及氧气的含量降低，呼吸才会被调整过来。最后，咳嗽反应在应对呼吸道中 *** 物时产生的不是睡觉时咳嗽而是呼吸停止。如果 *** 物足够严重，睡着的人会醒来清理气道，然后继续呼吸很可能再度入睡。
【6】发生在REM时期的多余的呼吸变化比发生在NREM时期的呼吸变化更显著。REM的空气交换量要比NREM低，因为尽管REM中呼吸更加急促，但也更加没有规律，包括一些简短的浅呼吸或呼吸暂停。另外，REM时期的呼吸更多取决于横膈膜而不是胸腔的作用。
