He remembered the survival skills his father had taught him and eventually hunkered (蹲下) down between rocks still warm from the sun to protect himself from the cold mountain night.‎ ‎“It was strange not having anybody with me, but I just kept going. I knew I had to make it back, or my family would be really sad，” Malachi said on Tuesday. Over the nearly 30 hours he was missing in the backcountry. He found river water to drink and even tried unsuccessfully to catch a fish with a spear made from a stick.‎ Meanwhile, dozens of search and rescue workers were searching the area on horses and ATVs (全地形车), as well as in the air, but they couldn’t spot Malachi in the wooded area.‎ As night fell and temperature dropped, Malachi wrapped his Tshirt around his legs, huddled in his jacket and protected himself from the weather between the rocks. The remaining warmth helped him get through the night.‎ Back at Paul Lake, his father, Danny Bradley, and a friend who had joined them for the camping were keeping a fire burning, hoping the boy might wander back by himself. As the hours wore on, Bradley imagined his son alone in the woods and was terrified that he might be hurt.‎ The next day, Malachi heard a police helicopter flying overhead. He knew the searchers aboard the craft couldn’t see him through the trees, so he started walking again until he found a clearing. He stayed there and briefly fell asleep until a search plane spotted him from the air and a helicopter landed to pick him up on Monday.‎ ‎“Malachi was found about five miles southeast of where he went missing，” Uintah County Sheriff Vance Norton said. It appeared that he wandered down a deep and narrow valley and over a hill before he found the clearing.‎ Malachi said he would go camping again, but next time he would not get away from other people. “I’ve learned from my mistakes，” he said.‎ 语篇解读：本文是一篇记叙文，讲述了一个在丛林中迷路的小男孩独自求生，并最终获救的故事。‎ ‎1．What did Malachi manage to do to survive?‎ A．Build a shelter on his own.‎ B．Catch a fish with a spear.‎ C．Stay between rocks at night.‎ D．Find a road to stop a passing car.‎ 解析：选C　细节理解题。根据第二段最后一句“... eventually hunkered (蹲下) down between rocks still warm from the sun to protect himself from the cold mountain night”和第五段中的“As night fell and temperature dropped ... protected himself from the weather between the rocks.”可知，他蹲在温暖的石头之间来抵御夜晚的寒冷。故选C项。‎ ‎2．How could the plane spot Malachi?‎ A．He kept waving and shouting loudly.‎ B．He stood on the top of a rock.‎ C．He used his Tshirt to make a signal.‎ D．He stayed in an area without trees or bushes.‎ 解析：选D　细节理解题。根据第七段中的“... so he started walking again until he found a clearing. He stayed there and briefly fell asleep until a search plane spotted him from the air ...”可知，为了让直升机发现他，他找到了一块林中空地。clearing意为“空地”。故选D项。‎ ‎3．We can infer from the passage that ________.‎ A．Danny Bradley kept a fire burning to let his son know the way back B．Malachi Bradley was searching for some flowers when he got lost C．Malachi always stayed where he went missing and waited for rescue D．Malachi’s teacher once taught him how to survive in a wilderness 解析：选A　推理判断题。根据第六段中的“Back at Paul Lake, his father, Danny Bradley, and a friend who had joined them for the camping were keeping a fire burning, hoping the boy might wander back by ‎ himself.”可知，他的父亲和一个朋友在营地让火一直燃烧，是希望男孩可以自己走回来。故选A项。‎ ‎4．What lesson does Malachi Bradley learn from the experience?‎ A．Be brave when in danger.‎ B．Stay close to others when camping.‎ C．Be cautious to take an adventure.‎ D．Believe in oneself when facing difficulties.‎ 解析：选B　细节理解题。根据最后一段中的“... but next time he would not get away from other people”可知，下一次他不会再离开其他人了。故选B项。‎ B Arctic sea ice is melting faster than expected, and that means big changes in Earth’s climate system.‎ That warning comes from the World Meteorological Organization (WMO). Its scientists are calling for the establishment of an Arctic observatory to help deal with possible dangerous changes resulting from the melting ice.‎ The WMO believes changes in the Arctic area are likely evidence of a coming disaster. It noted that temperatures around the world continue to rise. The next year is predicted to be the hottest year since modern recordkeeping began 150 years ago.‎ The Arctic is warming at least two times as fast as the world average, the WMO said. The highest Arctic sea levels in March were said to be the lowest on record.‎ Petteri Taalas is the WMO’s SecretaryGeneral. He said that the changes in the climate were having a serious result. For example, he said, the tree line in mountain areas is moving upward. “There are also some ‎ species of animals who have difficulties in coping with these changes，” Taalas said. These include polar bears, Arctic seals, and even some birds. He said the changing climate will also have an effect on fisheries. Taalas also warned that the melting of the Arctic’s frozen permafrost could release large amounts of greenhouse gases. Those gases are the ones that speed up the rise of temperatures.‎ But the melting of the Arctic sea ice is also opening up new transportation, travel and exploration possibilities. Taalas said that less ice could cut the time it takes for ships to sail between Europe and East Asia.‎ Opening the Arctic would also increase the risk of accidents in hazardous waters and oil spills. The cold, undeveloped environment is more difficult to clean up than other areas.‎ Taalas called for the establishment of an Arctic observatory to study, predict and react to climate change. He said this would keep transportation in Arctic waters safe.‎ 语篇解读：本文是一篇说明文，主要介绍了北极冰川加速融化及其带来的影响和应对措施。‎ ‎5．What’s the advantage of the melting Arctic sea ice according to the passage?‎ A．It prevents the greenhouse gases producing.‎ B．It will make summer not as hot as before.‎ C．An Arctic observatory needs to be set up.‎ D．It broadens traffic and science research.‎ 解析：选D　细节理解题。根据第六段第一句“But the melting of the Arctic sea ice is also opening up new transportation, travel and exploration possibilities.”‎ 可知，北极冰川的融化扩大了交通和科学研究的领域。故选D。‎ ‎6．What does the underlined word “hazardous” in Paragraph 7 mean?‎ A．Deep and freezing.　　 　 　B．Involving risk or danger.‎ C．Smooth and balanced. D．Safe and slow.‎ 解析：选B　词义猜测题。画线词所在句中的“hazardous waters and oil spills”和下句中的“The cold, undeveloped environment”应属同一类环境。hazardous与“寒冷和未开发的”相对应，应意为“危险的”。故选B。‎ ‎7．Where is the passage probably taken from?‎ A．A geography book. B．A school booklet.‎ C．A travel guide. D．A science report.‎ 解析：选D　文章出处题。本文主要介绍了北极冰川加速融化及其带来的影响和应对措施，并且文中列举了相关人士的观点，因此本文可能出自科学报告。故选D。‎ C We have a problem, and the strange thing is that we not only know about it, but also celebrate it. Just today, someone boasted to me that she was so busy she’s averaged four hours of sleep a night for the last two weeks. She wasn’t complaining; she was proud of the fact. She is not alone.‎ Why are typically rational people so irrational in their behavior? The answer is that we’re in the midst of a bubble. I call it “The More Bubble”．‎ The nature of bubbles is that something is absurdly overvalued until — eventually — the bubble bursts, and we’re left wondering why we were so irrationally animated in the first place. The thing we’re overvaluing now is the opinion of doing it all, having it all, achieving it all.‎ This bubble is being enabled by a combination of three powerful trends: smartphones, social media, and extreme consumerism. The result is not just information overload, but opinion overload. We are more aware than at any time in history of what everyone else is doing and, therefore, what we should be doing. In the process, we have been sold a bill of goods: that success means being supermen and superwomen who can get it all done. Of course, we boasted about being busy — it’s code for being successful and important.‎ And our answer to the problem of more is always more. We need more technology to help us create more technologies. We need to shift our workload to free up our own time to do yet even more.‎ Luckily, there is a solution to the pursuit of more: the pursuit of less, but better. A growing number of people are making this change. I call these people Essentialists.‎ These people are designing their lives around what is essential and removing everything else. These people arrange to have actual weekends (during which they are not working). They create technologyfree zones in their homes. They trade time on Facebook with calling those few friends who really matter to them. Instead of running to different meetings, they put space on their calendars to get important work done.‎ So we have two choices: We can be among the last people caught up in “The More Bubble”， or we can join the growing community of Essentialists and get more of what matters in our one precious life.‎ 语篇解读：本文是一篇议论文。受智能手机、社交媒体和极端消费主义的影响，许多人乐于说自己很忙，这掩盖了生活的本质。我们应当关注生活中最重要的部分，屏蔽那些无关紧要的事物。‎ ‎8．When the woman said for two weeks she only slept for four hours a night, ________.‎ A．she was unsatisfied with her lifestyle B．she was asking for suggestions C．she took pride in doing so D．she knew few people were like her 解析：选C　细节理解题。根据第一段第三句“She wasn’t complaining; she was proud of the fact.”可知，当这个女士说自己最近两周每晚只睡四个小时时，她对自己这样做感到自豪。故C项正确。‎ ‎9．What is Paragraph 4 mainly about?‎ A．The cause and result of “The More Bubble”．‎ B．The advantages of “The More Bubble”．‎ C．The solutions to “The More Bubble”．‎ D．The new trends of “The More Bubble”．‎ 解析：选A　段落大意题。通读第四段可知，该段首先分析了“The More Bubble”的起因：受智能手机、社交媒体和极端消费主义的影响；接着又分析了“The More Bubble”的后果：信息太多、观点太多，吹嘘忙就是成功和重要的秘诀。故A项正确。‎ ‎10．We can infer from the article that the author ________ “The More Bubble”．‎ A．is supportive of　　　　　 　B．is undecided about C．disapproves of D．wonders about 解析：选C　推理判断题。根据第四段第二句“The result is not just information overload, but opinion overload.”并结合第四段内容可知，“The More Bubble”导致信息膨胀、观点泛滥，从而掩盖了真实的生活；据此可以判断，作者对此持反对态度。故C项正确。‎ Ⅱ.阅读七选五 ‎(2018·江西重点中学联考)There are so many things we do in our daily lives that have become a “habit”. __1__ How you answer the phone is a habit. The way you sit in the car when you drive is a habit. Have you ever tried to change the way you do something, after you’ve done it in a certain way for so long? It’s not very easy to do. The minute your mind drifts to something else, you go right back to the old way of doing things. __2__ It’s a way of doing things that has become routine or commonplace. To change an existing habit or form a new one can be a tedious task.‎ Let’s pick something fairly easy to start with, like spending 15 minutes in the morning reading the Bible. If you want to turn something into a habit that you do every day, you have to WANT to do it. __3__ Make a firm decision to do this on a daily basis.‎ Imprint it in your mind. Write several notes to yourself and put them in places where you will see them. By the alarm clock, on the bathroom mirror, on the refrigerator door, in your briefcase, and under your car keys are good places to start.‎ After the newness wears off, then you will have to remind yourself, “Hey, I forgot to ...” Keep using the notes if you have to, __4__ Some people say it will take over a month to solidify it and make it something you will do without having to think about it. I tend to agree with the last statement. Two to three weeks will help you to remember, but thirty days or more will make it a part of your everyday routine.__5__‎ A．What is a “habit” anyway?‎ B．Is doing things in an old way good?‎ C．Brushing your teeth is a habit.‎ D．Forming a bad habit is easy.‎ E．It takes 16 to 21 times of repeating a task to make it a habit.‎ F．If you don’t, you will find a way to do everything but that.‎ G．That’s something you won’t necessarily have to think about before you do it — habit.‎ ‎1．选C　根据空格上一句“There are so many things we do in our daily lives that have become a ’habit’.”可知，我们日常所做的许多事情已经成了习惯；由空格下一句“How you answer the phone is a habit.”可知，接电话的方式也成了习惯；据此可以判断，空格处应列举日常生活中已经成为习惯的行为。C项“刷牙是一种习惯”紧密衔接上下文，符合语境。故C项正确。‎ ‎2．选A　根据空格下一句“It’s a way of doing things that has become routine or commonplace.”可知，该句阐述了习惯的定义；据此可以判断，空格处应提问“习惯是什么”。故A项正确。‎ ‎3．选F　根据空格上一句“If you want to turn something into a habit that you do every day, you have to WANT to do it.”可知，如果你想将某件事变成你每天都要做的习惯行为，你就必须想要做它，此处强调的是想要做的重要性；据此可以判断，空格处应谈论如果你不想做会发生什么情况。故F项正确。‎ ‎4．选E　根据空格下一句“Some people say it will take over a month to solidify it and make it something you will do without having to think about it.”可知，该处陈述的是养成习惯的一种方法。空格处应陈述养成习惯的另一种方法。E项中的“16 to 21 times”与下文中的“Two to three weeks”相照应。故E项正确。‎ ‎5．选G　根据空格上一句“Two to three weeks will help you to remember, but thirty days or more will make it a part of your everyday routine.”‎ 并结合空格处所在的位置可知，空格处总结全文，再次阐述什么是习惯。G项“那是你在做之前不必考虑的事——习惯”符合文意。故G项正确。‎ Ⅰ.完形填空 Cameron Lyle has never expected to save the life of a person he didn’t know. He was a shotput star at the highest point of his athletic career when he had to make a great __1__.‎ A man with blood cancer was __2__ for healthy bone marrow (骨髓) and Cameron was the only __3__among all the possible donors. The only __4__： if Cameron decided to donate, it meant he would miss some very important sports meetings.‎ ‎__5__ with cutting his career short, Cameron focused only on the __6__ to save the man’s life.‎ ‎“I was surprised that I was pretty __7__. I said “yes” right away，” said Cameron, 21.“If I had said __8__， he wouldn’t have had a match.”‎ Actually, Cameron had completely __9__ the “Be The Match Registry” that came to his university two years ago. But two months ago, he got a call. Cameron was __10__ he was a possible match for a young man with blood cancer, which would get worse quickly if not __11__.‎ Cameron received blood tests, which __12__he was a definite match.__13__he agreed to donate, more tests were followed to __14__he didn’t have any problem.__15__， everything went well, and last week Cameron headed to Massachusetts General Hospital in Boston to __16__ his bone marrow with a stranger.‎ Most people can return to their full activities within days after the donation.__17__ Cameron was told not to lift over 20 pounds for about a month. So this meant he __18__ to miss some athletic events where he ‎ wanted to __19__ after eight years of shotput training.‎ ‎“But it’s OK，” he said.“It was worth it I would __20__ it again.”‎ 语篇解读：一个处于事业巅峰期的铅球运动员，意外地与一个血癌病人的骨髓匹配成功。他毫不犹豫地为血癌病人捐献了自己的骨髓。虽然因此错过了一些重大赛事，但他觉得值得捐！‎ ‎1．A.schedule　　　　　　　　 　B．conclusion C．decision D．effort 解析：选C　下文中提到莱尔与一个血癌病人的骨髓匹配成功。由此可知，处于事业巅峰期的他不得不做一个重大决定。make a conclusion意为“得出结论”；make an effort意为“作出努力”。‎ ‎2．A.suitable B．desperate C．ready D．grateful 解析：选B　一个人患了血癌，他非常需要得到健康的骨髓。be desperate for意为“非常需要，极其需要”。‎ ‎3．A.match B．partner C．suit D．fit 解析：选A　莱尔是所有可能的捐赠者中唯一的匹配者。第8个空后的“he wouldn’t have had a match”有提示。‎ ‎4．A.solution B．situation C．assumption D．problem 解析：选D　根据下文中的“it meant he would miss some very important sports meetings”可知，莱尔面临的唯一问题是捐献骨髓会使他错过一些非常重要的赛事。‎ ‎5．A.Faced B．Concerned C．Delighted D．Disappointed 解析：选A　下文中提到莱尔决定捐献骨髓，这意味着他将面临事业上的短暂停顿。be faced with意为“面对”；be concerned with 意为“与……有关”。‎ ‎6．A.ability B．motivation C．way D．chance 解析：选D　根据上文“cutting his career short”可知，莱尔暂停了事业，把精力都集中在有可能挽救血癌病人的生命上。‎ ‎7．A.happy B．moved C．upset D．lucky 解析：选A　根据空后的“I said ’yes’ right away”可推知，莱尔为能够帮助别人感到非常高兴。‎ ‎8．A.yes B．hello C．no D．bye 解析：选C　如果莱尔说不，这个血癌病人很可能找不到成功的骨髓配型。‎ ‎9．A.organised B．forgotten C．avoided D．refused 解析：选B　联系下文中的“But two months ago, he got a call.”可知，事实上莱尔已经完全忘了匹配登记这件事。‎ ‎10．A.told B．warned C．reminded D．proved 解析：选A　结合上文中的“he got a call”可知，他被告知他可能与一个血癌病人配型成功。‎ ‎11．A.improved B．prevented C．recovered D．treated 解析：选D　根据上文中的“which would get worse quickly”可知，如果不治疗，病情就会快速恶化。‎ ‎12．A.doubted B．expected C．confirmed D．predicted 解析：选C　莱尔接受了血液检验，确认了他与病人配型成功。‎ ‎13．A.While B．Once C．Before D．Unless 解析：选B　分析句子的逻辑关系可知，一旦他同意捐献骨髓，之后就会有更多的检查。‎ ‎14．A.ensure B．ignore C．protect D．fear 解析：选A　莱尔需要做更多检查以确保他的身体没有任何问题。‎ ‎15．A.Quickly B．Gradually C．Suddenly D．Finally 解析：选D　根据空后的“everything went well”可知，最终，一切进展顺利，莱尔去医院捐献了骨髓。‎ ‎16．A.exchange B．share C．associate D．combine 解析：选B　根据语境可知，莱尔给血癌病人捐献骨髓，他与一个陌生人分享了骨髓。‎ ‎17．A.So B．Then C．But D．And 解析：选C　分析句子的逻辑关系可知，大多数人在捐献骨髓后的几天就可以完全恢复正常，但莱尔却被告知大约一个月内不能举20磅以上的东西。此处前后句之间表示转折关系。‎ ‎18．A.used B．agreed C．hesitated D．had 解析：选D　根据上文中的“Cameron was told not to lift over 20 pounds for about a month”可推断，他不得不错过很多赛事。‎ ‎19．A.grow B．shine C．cheer D．struggle 解析：选B　在经过八年的铅球训练后，莱尔一定想参加比赛，使自己表现出众。‎ ‎20．A.make B．admit C．accept D．do 解析：选D　莱尔认为自己所做的事很值得，因此他还会再做(同样的事情)。‎ Ⅱ.语法填空 A company in the USA is paying its workers to sleep more.

First, it is very convenient and saves a lot of time. Second, you can either eat it there or take it away. Third, the environment of fast food restaurants is both clean and comfortable. However, in terms of nutrition, fast food is far from satisfactory. It is usually not a balanced diet and low in nutritional value.‎ Fast food is only a good choice when you are in a hurry and turn to it once in a while. It’s good for people, especially children, to eat fast food as little as possible.‎
