airfare isn't getting any cheaper. Since you can't drive to all your dream destinations, flying is the only way to go sometimes and, undeniably, the fastest. Luckily, there are plenty of ways to find the most affordable fares and also avoid paying as many extra charges as possible when you plan ahead.Get the best fare. Airlines put out their fare sales on Tuesday morning, making this day the best day to book a flight for less.‎ Fly during the least popular times. Tuesday, Wednesday and Saturday are the slowest days to fly, which means cheaper deals than the rest of the week. You can also find reduced rates on early morning flights, since many people don't like to get up before the sun to get to the airport. Earlier boarding times can also considerably cut down your chances of getting bumped on an overbooked flight or delayed because of other delayed flights or mechanical issues.‎ Choose your seat later. Some airlines charge you to pick your seat when you book online, adding even more to the bottom line of your ticket cost. If you show up early on your travel day, you can still get suitable seats. Some of the best seats get held back until flight day, unless others are willing to pay extra for them ahead of time, so you still have the chance at one of those.‎ Fly on holidays. You already know that summer is the most expensive time to fly, and even though most other times are more affordable, the days surrounding holidays can be crazy. Save big if you're willing to travel on major holidays, such as Thanksgiving and ‎ Christmas.‎ Don't wait until the last－minute to book. Many travelers don't know that there's a sweet spot for booking and getting the best price on your tickets. Book too early or too late and you could end up paying more than you need to. The best time to book is between three months and six weeks from when you want to travel.‎ ‎【语篇解读】　本文主要讲述了在燃油费和机场建设费日益增长的今天，乘坐飞机会是非常昂贵的。本文告诉了读者几点减少费用，利用飞机便宜出行的建议。‎ ‎1．The passage is intended to ________.‎ A．inform us how to book a cheaper ticket B．tell us how to choose the seat and time for a flight C．persuade us into travelling by air D．inform us of some best ways to save money on a flight 答案与解析：D　推理题。根据文章内容，主要讲述了在燃油费和机场建设费日益增长的今天，乘坐飞机会是非常昂贵的。本文告诉了读者几点减少费用，利用飞机便宜出行的建议。结合Luckily, there are plenty of ways to find the most affordable fares and also avoid paying as many extra charges as possible when you plan ahead.目的在于给读者相关的建议，故选D。‎ ‎2．Which of the following statements is not true?‎ A．Airline travelers are supposed to pay more for the rising fuel costs.‎ B．Early morning flight will help avoid some bumps and delays.‎ C．You can only book your seat online before or on your flight day.‎ D．Booking too early may cost you more money on your tickets.‎ 答案与解析：C　细节题。根据文章内容If you show up early on your travel day, you can still get suitable seats. Some of the best seats get held back until flight day, unless others are willing to pay extra for them ahead of time, so you still have the chance at one of those.由此可知，并不是在你乘坐飞机的前一天或者当天才能在网上预订座位，故选C。‎ ‎3．Which is the best time to book the flight for October 2nd?‎ A．May 15th.　 B．August 15th.‎ C．June 15th. D．September 15th.‎ 答案与解析：B　推理题。根据文章内容The best time to book is between three months and six weeks from when you want to travel.预订机票的最后时机是你想要乘机的前3个月至6个星期前。如果想要10月2号出行，结合4个选项，则最佳的订票时间应为8月15号。故选B，其他时间要么过早要么过迟。‎ B ‎(2018·安徽皖南八校联考)‎ If you want to slow aging, you might want to eat less. This finding is good news－if you were a mouse. The researchers studied mice, not people.‎ John Price and other researchers studied two groups of mice. One group was able to eat as much as it wanted. The researchers limited what the mice in the other group ate. Their diet had 35 percent fewer calories than the first group of mice.‎ Price says the mice with the diet restrictions were“more energetic and suffered fewer disease.”They were not just living longer but seemed to stay younger for a longer period of time.‎ The researchers found that fewer calories slow down a natural mechanism in cells called ribosomes. Price explains that ribosomes are responsible for making important proteins in the cells. But with fewer calories, they slow down. This gives the cells more time to repair themselves.‎ The researchers say ribosomes use from 10 to 20 percent of the cell's energy to make those proteins. Price wrote that “because of this, it is impractical to destroy an entire ribosome” when it starts to break down. However, “repairing individual parts of the ribosome on a regular basis enables ribosomes to continue producing high quality proteins for longer than they would otherwise. This top quality production, in turn, keeps cells and the entire body functioning well.”‎ Price said, “ribosome is a very complex machine, like a car.” They need “maintenance to replace the parts that wear out the fastest. When tires wear out，” he explained, “you don't throw the whole car away and buy a new one. It costs less to replace the old tires.”‎ ‎“Food，” he said, “isn't just material to be burned－it's a signal that tells our body and cells how to respond.” Price said the findings help to explain how exactly our bodies age. And this may “help us make more educated decisions about what we eat.”‎ ‎【语篇解读】　本文属于科技与发明类。主要介绍了通过在老鼠身上所作的实验，发现减少食物有利于身体健康，让人更长寿。‎ ‎4．What can we know about the mice with limited calories from the study?‎ A．They can keep healthy easily.‎ B．They need more energy to be active.‎ C．They can look younger than they are.‎ D．They will live a longer life like humans.‎ 答案与解析：A　推理判断题。根据第三段“the mice with the diet restrictions were ‘more energetic and suffered fewer disease’”饮食限制的老鼠更精力充沛，患疾病的几率也更小。根据句意可知限制饮食的老鼠更健康，故选A。‎ ‎5．What will happen to ribosomes if there are fewer calories?‎ A．They will completely break down.‎ B．They make proteins in the cells slowly.‎ C．They will produce high quality proteins more.‎ D．They may need more time to repair themselves.‎ 答案与解析：B　推理判断题。根据第四段句意：研究人员发现更少的热量减慢了称为核糖体的细胞的自然机制。Price说明核糖体负责制造细胞中重要的蛋白质。但是热量越少，它们就制造的速度越慢。分析本句可知核糖体在细胞中制造蛋白质的速度减慢了。故选B。‎ ‎6．Price explained the ribosomes' role of repairing themselves by ________.‎ A．telling a story B．listing basic data C．making comparisons D．experimenting on mice 答案与解析：C　推理判断题。根据第六段：普赖斯说：“核糖体是一个非常复杂的机器，就像一辆汽车。”他们需要“维修”来替换最快磨损的部件。“当轮胎磨损时，”他解释道，“你不要把车全扔掉，买一辆新的。更换旧轮胎成本较低。”普赖斯把核糖体比作是一辆非常复杂的汽车，可知是通过比较的，故选C。‎ ‎7．What does the text mainly deal with?‎ A．Food decides how long you live.‎ B．Can you slow down your aging process?‎ C．Eating less may help you live longer.‎ D．Should your diet be reduced for your health?‎ 答案与解析：D　主旨大意题。根据第一段可知想要年轻就要少吃。第三段限制食物的老鼠要更活跃更健康。及最后一段这可能会“帮助我们对我们所吃的东西做出更多的教育决定”。可知为了健康应该减少食物。故选D。‎ C ‎(2018·湖北枝江第二高级中学模拟)‎ Ammie Reddick from East Kilbride, Lanarkshire, was only 18 months old when she had the accident that had scarred(留下创伤) her for ‎ life. The curious child reached up to grab the wire of a hot kettle in the family kitchen and poured boiling water over her tiny infant frame.‎ Her mother Ruby turned round and, seeing Ammie horribly burnt, called an ambulance which rushed her daughter to a nearby hospital. Twenty percent of Ammie's body had been burned and all of her burns were third－degree. There, using tissue (组织) taken from unburned areas of Ammie's body, doctors performed complex skin transplants(移植) to close her wounds and control her injuries, an operation that took about six hours. Over the next 16 years, Ammie underwent 12 more operations to repair her body.‎ When she started school at Maxwelton Primary at age 4, other pupils made cruel comments or simply wouldn't play with her. “I was the only burned child in the street, the class and the school，” she recalled, “some children refused to become friends because of that.”‎ Today, aged 17, Ammie can only ever remember being a burned person with scars; pain is a permanent part of her body. She still has to have two further skin transplants. Yet she is a confident, outgoing teenager who offers inspiration and hope to other young burns victims.‎ She is a member of the Scottish Burned Children's Club, a charity set up last year. This month, Ammie will be joining the younger children at the Graffham Water Center in Cambridge shire for the charity's first summer camp. “I will show them how to get rid of unkind stares from others，” she says. Ammie loves wearing fashionable sleeveless tops, and she plans to show the youngsters at the summer camp that they can too. “I do not go to great lengths to hide my burns scars，” she says, “I gave up wondering how other people would react years ago.”‎ ‎【语篇解读】　本文讲述Ammie Reddick十八个月的时候遭遇一场意外，被热水壶烫伤，做过十几次皮肤移植手术，身上留下了很多的伤疤，从小遭受了很多的白眼。但她非常自信、开朗，经常鼓励其他烫伤的小患者，让他们充满希望。‎ ‎8．What did other children do when Ammie first went to school?‎ A．They were friendly to her.‎ B．They showed sympathy to her.‎ C．They were afraid of her.‎ D．They looked down upon her.‎ 答案与解析：D　考查细节理解题。根据第三段“other pupils made cruel comments or simply wouldn't play with her”可知其他同学不是对她冷嘲热讽，就是不愿意跟她一起玩，故选D项。‎ ‎9．Ammie will teach the younger children at the Graffham Water Center to ________.‎ A．face others' unkindness bravely B．hide their scars by proper dressing C．live a normal life D．recover quickly 答案与解析：A　考查细节理解题。根据最后一段“I'll show them how to get rid of unkind stares from others，”得知Ammie教他们如何对他人不友好的注视嗤之以鼻，故选A项。‎ ‎10．What does the underlined word “permanent” in the 4th paragraph mean?‎ A．Necessary. B．Lifelong.‎ C．Difficult. D．Important.‎ 答案与解析：B　考查细节理解题。文章中提到，Ammie在过去的17年里接受了超过12次手术，接下来她还要做两次皮肤移植手术，所以她的痛苦是“永久的、终生的”，故选B项。‎ ‎11．What can be the best title of the passage?‎ A．A Seriously Burned Girl Survives B．Ways to Get Rid of Unkind Stares C．Permanent Scars And Pain For a Girl D．A seriously burned angel of Hope 答案与解析：D　主旨大意题。纵观全文，可以看出本文主要讲述了一个被烧伤的女孩的身残志坚的励志故事，故选D项。‎ D ‎(2018·宁夏银川市长庆高中一模)‎ Being less than perfectly welldressed in a business setting can result in a feeling of great discomfort that may well require treatment to eliminate (remove). And the sad truth is that “clothing mismatches” on the job can ruin the day of the person who is wearing the inappropriate attire(着装)－and the people with whom he or she comes in contact.‎ Offices vary when it comes to dress codes. Some businesses have very high standards for their employees and set strict guidelines for office attire, while others maintain a more relaxed attitude. However, it is always important to remember that no matter what your company's attitude is regarding what you wear, you are working in a business environment and you should dress properly. Certain items may be more appropriate for evening wear than for a business meeting, just as shorts and a Tshirt are better suited for the beach than for an office environment. Your attire should reflect both your environment and your position. A senior vice president has a different image to maintain than that of a secretary or sales assistant. Like it or not, you will be judged by ‎ your personal appearance.‎ This is never more apparent than on “dressdown days”， when what you wear can say more about you than any business suit ever could. In fact, people will pay more attention to what you wear on dressdown days than on “business professional” days. Thus, when dressing in “business casual” clothes, try to put some good taste into your wardrobe choices, and recognize that the “real” definition of business casual is to dress just one notch (等级) down from what you would normally wear of business－professional attire days.‎ Remember, there are borders between your career and our social life. You should dress one way for play and another way when you mean business. Always ask yourself where you are going and how other people will be dressed when you get there. Is the final destination the opera, the beach, or the office? Dress properly and you will discover the truth in the principle that clothes make the man－and the woman. Unless you are sure what to wear, it pays to dress slightly traditionally than the situation demands.‎ ‎【语篇解读】　本文是一篇说明文，主要介绍了关于在商业领域如何恰当的穿衣。即使没有固定的规定，也应该按照商业背景穿衣，作者给出了如何适当穿衣的建议。‎ ‎12．What is the passage mainly about?‎ A．The differences between professional and casual dress.‎ B．The relationship between career and social life.‎ C．How to dress properly in a business setting.‎ D．Dressing codes vary in different situations.‎ 答案与解析：C　主旨大意题。纵观全文，可知这篇文章是关于在商业领域如何恰当的穿衣。故C选项正确。‎ ‎13．Which of the following statements is true?‎ A．Every company has strict rules regarding office dress.‎ B．You should dress according to the business setting even when there are no fixed rules.‎ C．You can wear whatever you like if your company doesn't have high standards for it.‎ D．In companies with relaxed rules on office dress, you can't spot a manager among others.‎ 答案与解析：B　细节理解题。根据However, it is always important to remember that no matter what your company's attitude is regarding what you wear, you are working in a business environment and you should dress properly.可知即使没有固定的规定，也应该按照商业背景穿衣，故B选项正确。‎ ‎14．Which statement best describes “dressdown days”？‎ A．People are usually more careful about what they wear on dressdown days.‎ B．People's clothes on dressdown days don't receive much attention.‎ C．We can't judge a person's taste by his clothes on dressdown days.‎ D．On dressdown days, you can wear whatever you like.‎ 答案与解析：A　词义猜测题。根据This is never more apparent than on “dressdown days”， when what you wear can say more about you than any business suit ever could.可知“dressdown days”，指的是人们更关注穿衣的时候。故A选项正确。‎ ‎15．Which of the following is NOT the rule offered in the passage regarding business dress?‎ A．Remember to ask others for advice when you don't know what to dress.‎ B．Dress a bit traditionally if you are not sure what to wear.‎ C．For a business meeting and a concert, you should dress differently.‎ D．Think about how other guests will wear if you are invited to a dinner.‎ 答案与解析：A　细节理解题。根据最后一段的句子：Always ask yourself where you are going and how other people will be dressed when you get there.可知BC是对的，从最后一句话Unless you are sure what to wear, it pays to dress slightly traditionally than the situation demands.可知D是对的，所以可以说A项的表述是错的。故A选项正确。‎ Ⅱ.七选五 ‎(2018·衡水中学高三大联考)‎ How to Be More Creative Every Day Creativity isn't something you either have or don't have. In fact, it is something like playing the saxophone. __1__ So read on to know how.‎ ‎·Be more curious.‎ It's important to seek out new viewpoints every day. __2__ To involve this in your daily life, make sure to keep an open mind when you're presented with an idea, and be curious as to what else is around the corner.‎ ‎·Give yourself space.‎ Letting every piece of information into your brain drags you from being creative. Try to apply a level of space into your everyday life. __3__ It helps to lead your thinking patterns away from potential distractions (使人分心的事物), leaving much room to have creative ‎ ideas.‎ ‎·Try something new.‎ Frequent thinking patterns, in effect, cause you to be more likely to think the same things or make the same decisions over and over unless you get out of your comfort zone. __4__ Though not always easy, it does open up a whole new world of thinking!‎ ‎·__5__‎ Social media has created an environment where we're constantly shown whether we've succeeded in the form of likes or comments, which leads us to doubt ourselves. However, creativity is a journey, and you're learning every step of the way. Honestly, you'll learn much more from that than a straight win anyway. So be confident and tell yourself you have already done well enough.‎ A．Learn from failure.‎ B．Remind yourself you're good enough.‎ C．The 8 p．m.8 a．m. phone ban is a great way to begin.‎ D．Getting physical really helps to sort out your brain space.‎ E．But it's not easy to feel or be automatically creative either.‎ F．Thus you can think and approach things from another angle.‎ G．Using your skills in a different area is a great way to think outside the box.‎ 体裁：说明文　题材：介绍说明　主题：如何变得更有创造力 ‎【语篇导读】　本文介绍了几种如何使自己变得更有创造力的方法。‎ ‎1．答案与解析：E　上文提到它有点像吹奏萨克斯，设空处应该介绍如何像萨克斯，主语应该与上文一致，但意义上转折，以便引出下文的建议。故选E项。‎ ‎2．答案与解析：F　本段主题是更好奇。设空前提到每天寻找新的观点很重要，F项(这样你可以从另一个角度思考和处理问题)与上文一致，也与下文的to keep an open mind相照应。故选F项。‎ ‎3．答案与解析：C　本段主题是给自己空间。本段第一句提到进入大脑的每一条信息都会阻碍你的创造性，并建议每天给自己留一定空间。空格后提出，这有助于让你的思维模式远离潜在的干扰，给创造性的思维留下更多的空间。C项(晚8点到早8点的手机禁令就是一个好方法)符合上下文语境。故选C项。‎ ‎4．答案与解析：G　本段主题是尝试新事物。G项(在不同的领域使用你的技能是跳出框架思考的一个好方法)与主题一致。故选G项。‎ ‎5．答案与解析：‎ B　本题考查段落主题。本段第一句提出在社交媒体上，我们成功与否常常会以喜欢或评论的方式呈现出来，这让我们总是怀疑自己。其中的关键词doubt表明一种不自信，再结合最后一句So be confident and tell yourself you have already done well enough.可知，本段的主题是要让自己自信。故选B项。‎
