10、make up for your lost sleep during the weekends. But is it useful?A study published in the journal Current Biology shows that the habit of sleeping in on weekends doesnt fix the damage that has been done by a lack of sleep during the week. Even worse, it may damage your health.In the study, which wa

11、s conducted over 10 days, 36 healthy young men and women with different sleep requirements were divided into three groups. The first group were asked to sleep nine hours a night and the second group five hours a night. The members of the third group slept for five hours on weekdays but rested as lon

12、g as they wanted on the weekend.The researchers found that people who lacked sleep ate more snacks and gained weight quickly. However, this wasnt the case for the first group.That could be partially due to the shifting of the biological clock and changes to certain body hormones, especially hunger h

13、ormones. In order to catch up on their sleep during weekends, people in the third group would eat later as a habit. So their biological clocks shifted, which also changed the production of hunger hormones.“The hormone leptin(瘦素) decreases appetite(胃口), while the hormone ghrelin(饿素) increases appetit

14、e,” explained US researcher Vsevolod Polotsky. “Sleep shortage causes leptin to drop and ghrelin to rise, so youre hungry and eat more.”And even if they tried to sleep for as long as they wanted to during weekends, according to researchers, it was still not enough because they found it difficult to

15、fall asleep.Moreover, short and insufficient sleep schedules will lead to an inability to change blood sugar and increase the risk of metabolic(新陈代谢) disease in the long term.4Which of the following is true about the study?AParticipants were divided into two groups.BResearchers studied 36 children a

Thats exactly what BionicGym, an advanced wearable neuro-stimulator (神经刺激器), claims to help you achieve.Lets be honest, weve all seen similar devices in sci-fi movies or teleshopping advertisements before, bu

19、t theyre really not that effective. However, BionicGym creator Dr Louis Crowe says this product is truly revolutionary.Crowe says he came up with the idea for this unique neuro-stimulator over 16 years ago, when he would get into the cold Atlantic ocean so he could observe the effects of shivering (

20、颤栗). He discovered that as he got colder he didnt shiver faster, but he shivered at the same rate. He also found that this natural way of burning calories allowed a person to burn a lot of calories without actually doing any exercise.Crowe did more research on how to use shivering as an effective tr

21、aining and weight-loss tool, and developed BionicGym. Hes teamed up with Dr Barry Broderick to bring it to market. To do so, they need some funding to redesign the device. Then it has to be approved by regulators. BionicGym may be ready for sale by November this year. But people seem so impressed by

22、 the abilities of BionicGym to give them a workout while resting on a sofa that they seem to have no problem parting with $ 300 for the chance to one day try it out.

55、the United States.They had their apparent differences. Acaimie had always been the worrier. Clay, on the other hand, was an optimistalways certain that things would turn out just fine. So it was Clay who wanted to take a day of their honeymoon and climb Mount Liamuiga, which is also a dead volcanoa

61、绍了一些防火信息，包括火灾警报、防火演练、灭火器和烟雾探测器的注意事项。1细节理解题。根据第一段中的“They inspect all campus buildings and maintain all sprinkler systems, fire alarms and fire extinguishers.(他们检查校园里的所有建筑物，并维护所有的自动喷水灭火系统、火警警报器以及灭火器)”可知，防火专业人员的主要职责是检查和保养防火设备。故选C。2细节理解题。根据Fire Drills部分中的“Take your room key and ID. Close and lock the do

62、or to your room. Exit immediately from the nearest emergency exit and do not use a lift.(带上你的房间钥匙和身份证。关好房间的门并锁上。立即从最近的紧急出口离开，不要使用电梯)”可知，在防火演练中，学生们应该关上房门迅速离开。故选C。3推理判断题。根据 Smoke Detector部分中的“If your smoke detector is working properly, the red light should be on.(如果烟雾探测器正常工作，红灯应该是亮的)”可推知，为了保证烟雾探测器的安全运

63、行，必须确保红灯能正常亮起。故选D。4D5C6B7C【解析】【分析】这是一篇说明文。文章介绍了发表在当代生物学杂志上的一项研究表明，周末睡懒觉的习惯并不能弥补工作日睡眠不足造成的损害。更糟糕的是，它可能会损害你的健康。【详解】1.细节理解题。根据第三段中“The first group were asked to sleep nine hours a night and the second group five hours a night. The members of the third group slept for five hours on weekdays but rested a

64、s long as they wanted on the weekend.”可知，第一组每晚睡9个小时，第二组每晚睡5个小时。第三组的成员在工作日睡5个小时，但是在周末想睡多久就睡多久。所以参与的三组人员的睡眠要求不一样。选项D与文意相符。故选D。2.词句猜测题。根据下文中“ changes to certain body hormones, especially hunger hormones.”可知，某些身体荷尔蒙的变化，尤其是饥饿荷尔蒙。结合and，可以推测，此处与下文在意义上为并列关系，画线词应与changes 意思相近，所以此处指生物钟的改变。选项C符合题意。故选C。3.细节理解题。

65、根据倒数第三段最后一句“Sleep shortage causes leptin to drop and ghrelin to rise, so youre hungry and eat more.”可知，睡眠不足导致瘦素下降，饥饿激素上升，所以你饿了，吃得更多。选项B与文意一致，故选B。4.主旨大意题。结合第二段内容“A study published in the journal Current Biology shows that the habit of sleeping in on weekends doesnt fix the damage that has been done b

66、y a lack of sleep during the week. Even worse, it may damage your health.”可知，发表在当代生物学杂志上的一项研究表明，周末睡懒觉的习惯并不能弥补工作日睡眠不足造成的损害。更糟糕的是，它可能会损害你的健康。同时结合第三段对此研究过程的介绍，研究中36名健康男女参与人员分成三组，每组人员的睡眠要求不同，结果表明第一组人员可能部分是因为生物钟的改变和身体某种荷尔蒙的改变外，其他两组表现出缺乏睡眠的人会吃更多的零食，体重增加很快。此外，睡眠时间短和不足会导致血糖无法改变，长期而言会增加患新陈代谢疾病的风险。因此，文章主要介绍的是

67、补觉会伤害身体。选项C与文意一致。故选C。8B9D10C11B【解析】【分析】本文是一篇说明文，主要讲述了先进的可穿戴神经刺激器Bionic Gym，可以帮助消耗热量，有利健康。8推理判断题。根据第一段“Thats exactly what BionicGym, an advanced wearable neuro-stimulator (神经刺激器), claims to help you achieve.”(那正是先进的可穿戴神经刺激器Bionic Gym声称可以帮助你实现的)，可知，that指代上文提的问题，因此推断作者在第1段中提出问题是为了引出本文的主题，从第二段起开始讨论这种设备。

68、故选B 。9细节理解题。根据第三段的“Crowe says he came up with the idea for this unique neuro-stimulator over 16 years ago, when he would get into the cold Atlantic ocean so he could observe the effects of shivering (颤栗).”(克劳说，他16年前就想到了这种独特的神经刺激器的想法，当时他进入寒冷的大西洋，以便观察颤抖的效果)可知，克劳对BionicGym的灵感来自他自己的经验。故选D。10推理判断题。根据第四段“

69、But people seem so impressed by the abilities of BionicGym to give them a workout while resting on a sofa that they seem to have no problem parting with $ 300 for the chance to one day try it out. Crowes crowdfunding campaign had a goal of $ 20, 000, but with 11 days to go, its already passed the $

70、287. 000 mark.”(但是人们似乎对BionicGym在沙发上休息时进行锻炼的能力印象深刻，以至于他们对于只要300英镑就可以尝试一天毫无困难，克劳的众筹活动的目标是$20,000，但在还有11天的时候，它已经达到了$287000的成绩。)可推断，第4段的数字主要表示公众对BionicGym表现出极大的热情。故选C 。11推理判断题，根据最后一段“Beginners or older people can use it at lower levels and make their way up to the tougher programs.”(初学者或年长的人可以在较低的水平上使用

71、它，并逐步提高难度)可推断，Bionic Gym可以满足不同人的需求。故选B。12B13B14D15C【解析】【导语】这是一篇说明文。作者主要介绍了热石疗法的对人们身体健康的益处。12标题判断题。根据第二段“One popular option is hotstone massage (按摩). ”（一个受欢迎的选择是热石按摩）可知这是这段的主题句。以及第三段的“Another popular option is hotstone baths.”（另一个受欢迎的选择就是热石洗浴）可知这是这段的主题句。再根据最后一段“The hotstone therapy can help cure many

72、 diseases，including back pain.”（热石疗法可以帮助治疗许多疾病，包括背部疼痛。）可知整篇文章都是围绕热石疗法的好处来展开的。所以这篇文章最好的标题可能是热石疗法的神奇功能。故选B。13细节理解题。根据第三段“The hotstone bath will help the body discharge toxins and humidity that accumulated during the last winter.”（热石浴有助于人体排出去年冬天积累的毒素和湿气。）可知人们通过排出大量的汗水来释放体内的毒素。故选B。14细节理解题。根据文章第一段“While

73、people are annoyed by it，experts suggest summer is the best season to discharge (排放) your bodys toxins (毒素) and recover your energy.”（虽然人们对此感到恼火，但专家建议，夏天是排出体内毒素、恢复精力的最佳季节。）可知通过这篇文章我们可以知道人们应该利用夏天来增进健康。故选D。15细节理解题。根据最后一段“The therapy is gaining wide popularity with many people，especially those who have

74、 jobs in cool airconditioned rooms.The hotstone therapy can help cure many diseases，including back pain.”（这种疗法在很多人中越来越受欢迎，尤其是那些在冷气房工作的人。热石疗法可以帮助治愈许多疾病，包括背痛。）可知关于热石疗法我们可以了解到它以其良好的效果受到人们的欢迎。故选C。16A17F18C19D20G【解析】【导语】本文是一篇说明文。文章中作者认为每个人至少要学一些最基本的急救知识，这可能是非常重要的，并且介绍了一些获得急救知识的理由。16根据空格后一句“However, at th

75、e same time I fell a bit sad.(然而，与此同时，我感到有点悲伤)”可知，“However”表示转折，与“sad(悲伤的)”相对的是“happy(高兴的)”，A选项I was happy to hear that (听到这个我很高兴)符合题意，且选项中的“that”指代的就是空格前提到的“我所做的一切帮助挽救了老人的生命”这件事。故选A。17根据空格前一句“I think everyone should learn at least some basic first-aid techniques, which can be very important.(我认为每个人

76、都应该至少学习一些基本的急救技巧，这可能非常重要)”，再结合空格处位于第一段的末尾，有承上启下的作用，接下来三段首句都以“You can(你可以)”开头，是列举了我认为应该至少学习一些基本的急救技巧的理由。F选项Here are my reasons(以下是我的理由)符合题意。故选F。18根据空格后一句“you can act whenever youre needed.(你可以在任何你被需要时去行动)”可知，前一句是一个从句，应该提到如果你有前文提到的“the knowledge, skills and confidence(知识、技能和信心)”。C选项If you have the ski

77、lls(如果你有这些技能)符合题意。故选C。19根据本段第一句“You can stay safe at work.(你可以在工作中保持安全)”可知，本段讲的是安全问题，结合空格后一句“and you can also help meet your workplaces safety requirements.(你也可以帮助满足工作场所的安全要求)”中的“you can also”提示前后句有并列关系，D选项With first-aid knowledge you can create a safe work environment (有了急救知识，你可以创造一个安全的工作环境)中含有“you

78、 can”且内容与安全相关。故选D。20根据空格后一句“The first-hand experience you gain through learning first aid and using your skills could help you decide if you want to pursue a career in the health profession.(通过学习急救和运用技能获得的第一手经验可以帮助你决定是否要从事卫生职业)”可知，本段提到的是未来的职业规划，放在句首的是本段的主题句，G选项Its helpful to your future career (这对你未

79、来的职业生涯很有帮助)符合题意。故选G。21C22A23B24D25A26C27D28A29C30A31C32D33A34D35C【解析】【导语】这是一篇说明文。作者主要介绍了关于急救的一些知识与重要性。21考查名词词义辨析。句意：急救可以挽救生命或改善某些生命体征，包括脉搏、体温、气道通畅和呼吸。A. chance机会；B. disaster灾难；C. life生活；D. family家庭。根据上文“First aid is emergency care for a victim of sudden illness or injury until more skillful medical
