(用省略句改写) →________________________， Steve and I repeatedly stammered our heartfelt thanks to him.   is that it is easy for visitors to find When led out of the forest (三)赏修辞之功 As the Chinese philosopher Laozi wrote， “A journey of a thousand miles begins with a single step.” 赏析:本句使用了“引用”修辞。引用是指在写作中引用现成的话，如诗句、格言、成语等，以表达自己的思想感情的修辞方法。这里作者通过引用哲学家老子的名言，增强了其观点的说服力。 提能训练/完成句子 ①As an old saying goes， “ _________________________.”  正如俗话所说，“态度决定一切。” ②As Confucius said， “_________________________________ _________ from afar?”  正如孔子所说，“有朋自远方来，不亦乐乎?” Attitude decides everything Isn’t it always a pleasure to greet a friend (四)赏逻辑之巧 Firstly， there is a “cue”， ... Secondly， there is a “routine”， ... Thirdly， there is the “reward”， ... 赏析:以上三句是平行句，是并列关系。这三句以表示顺序的三个副词“firstly， secondly， thirdly”开头，清晰地说明了什么是“habit cycle”。这种说明方法常用于解决问题或说明事理的说明文中，或者用在议论文中列举论据、观点或事实等。 提能训练/翻译语段 首先，你应该保持冷静。其次，你可以和你的父母谈谈。第三，你应该打电话给你的朋友，向他/她道歉。 Firstly， you should keep calm. Secondly， you can talk to your parents. Thirdly， you should call your friend up and say sorry to him/her.  美文阅读润心 NO.3 习惯的力量是强大的。日常生活中，我们一旦养成某种习惯，它就能左右我们的生活。好习惯能让人们的工作、学习和生活充满成功的希望，而坏习惯则可能让人深受其害，难以自拔。然而，习惯是可以控制和改变的。认识不良生活习惯的危害，改变坏习惯，养成好习惯，可以为未来的幸福生活奠定坚实的基础。 4 Ways to Get Rid of Habits that Are Holding Your Life Back Everyone has some bad habits that they would like to break free from. Bad habits act as barriers that hinder a person from making any progress in life. They can hurt a person — both mentally and physically. For most of us， these habits are so deeply rooted that it becomes hard to even notice them. The first thing that you need to understand is that it’s not your fault; it’s the way our brains are wired. When a person is suffering from bad habits， the brain is secretly working to ruin any efforts they make to break free from them. Your brain loves routine， and it tries its best to make sure that you don’t change your routine.  But， there are 4 ways to make sure you can break free from bad habits and adopt a healthy lifestyle. ① Adopt a New Habit If you want to get rid of a bad habit， you need to replace it with something else. So， in order to break free from it， you have to pave a new path for your brain. Anything that is done in excess can be termed as a bad habit. If you watch too much television， you can replace it with a healthy habit such as reading a book or exercising. It might also be a time to start something that you have been planning to do for a long time. Maybe you can start working on a dream project you have been delaying for so long， or you can take a holiday that you have been desperately wanting. Anything that offers a change in schedule can be very beneficial for you.  ② Get Proper Help A lot of times， people who are suffering from bad habits， like to deal with everything themselves. They often forget that they have friends and family who can offer them support. Moreover， there are a lot of professional therapists who offer their support. For example， if you are suffering from tobacco or alcohol problems， you can get help from ARC Rehab Centre. Rehabilitation centers like these can help people recover at a faster and better rate so that you can finally have the life that you want to have. Cut Out Triggers from Your Life Triggers are anything that causes you to engage in your bad habit. For example， if you smoke or drink alcohol around certain people， you should cut off all ties with them for your own good. When a person is dealing with a bad habit， the environment he surrounds himself with is one of the greatest driving factors that either help him or make it harder for him to leave bad habits. You can also pair up with a person who makes it easier for you to give up your bad habit and act as your motivator. Set Futuristic Goals You should imagine a future that involves a life without your bad habit. Whatever the habit you are looking to get rid of, you should visualize how much better your life would become once you get rid of it. Think of all the mistakes you have made， relationships that turned sideways， or all the opportunities you failed to seize just because of your bad habits. By setting goals for the future， you can motivate yourself and adopt a lifestyle that helps you achieve those goals.  ③ 阅读理解 1.Why is it difficult for people to break bad habits according to the text? A.Because people are too lazy to change. B.Because the brain prefers routine and resists change. C.Because bad habits are not obvious at all.

B.Starting a long⁃planned project is always easier than other new habits. C.Changing the daily schedule can help break bad habits.

Back in 2014， the 25⁃year⁃old then was fully occupied with her work and graduate study in Dublin， mostly eating on the go. “I was feeding on quick， easy food like sandwiches，” she said. “I stayed up a lot and the gym was a foreign concept for me for I did not work out at all.” That changed the following year when Walsh needed a convenient， reliable and budget⁃friendly way to get to and from class. “Driving was expensive， and public transportation in the Irish capital left much to be desired，” she said. She turned instead to cycling. At first， Walsh was doubtful. “I didn’t want to wear the same suits like other riders because it looked strange for me，” she joked. But as soon as she gave it a go， she was spellbound. The six miles she had to cover on her commute (通勤) didn’t seem like so much. “I can’t believe how quick and easy that was，” Walsh said. “The more I cycled， the easier it got， and I started getting faster. I think what I enjoyed the most was the freedom the bike gave me.” In early 2016， she took the next step and joined a local cycling club， where she took part in long group rides. But something incredible was happening at the same time. As her weekly mileage (里程数) increased， her unhealthy habits fell by the wayside. She cleaned up her diet and cut back on burning the midnight oil. “I gradually got rid of that bad habit after joining in training，” she said. Then， thanks to the encouragement of other club members， she tried another kind of racing. At first， she was overwhelmed by the competition， getting dropped by other members on every climb. Yet she kept pushing and viewing the failures as learning experience. “I was enjoying the challenges and was more confident，” she said. 语篇解读:本文是一篇记叙文。文章讲述了Orla Walsh由于公共交通工具的不便慢慢爱上了骑行，并且坚持骑行下去的故事。 1.

Dr. Ryan Broderick， a doctor at the University of California San Diego， recently tested a VR headset with “spatial (空间的) computing” during surgeries (外科手术)， becoming one of the first doctors in the U. S. to try this technology. “With these headsets， we can project medical images into the real world of the surgery room，” Broderick explains. “We can make screens as big as a wall or adjust them to the perfect position.” This technology mixes digital images with real⁃world views， letting doctors see 3D models of a patient’s body — like where a tumor (肿瘤) is — almost like giving them X⁃ray view. In the past， doctors had to frequently turn their heads to check screens during complex surgeries， leading to neck and shoulder pain. Now， spatial computing shows all key information right in front of their eyes. “It works like a car navigation system — highlighting danger areas or warning us to avoid important areas，” says Broderick. The tech also helps train new doctors. Teachers can use virtual screens to show body structures， point out key areas with glowing arrows， or even draw where to make cuts on a 3D heart model. “Students can watch the teacher’s virtual explanations， which is clearer than reading textbooks!” Broderick adds. This hands⁃on learning helps trainees master skills faster. Top U. S. hospitals are already testing similar systems. Though the equipment is expensive and needs software improvements， Broderick remains hopeful: “This isn’t just new tools — it’s a revolution in healthcare. In 10 years， technology like this could help millions get better treatment.” From video games to life⁃saving surgeries， VR is proving that cool tech can truly change lives. 语篇解读:本文是一篇说明文。文章主要讲述了虚拟现实技术在手术中的应用及其带来的好处。 5.How can headsets help with surgeries according to paragraph 2? A.By making the surgery room brighter. B.By letting doctors avoid looking at screens. C.By helping patients stay calm during surgery. D.By showing 3D pictures of a patient’s body. √ 解析:细节理解题。根据第二段中“This technology mixes digital images with real⁃world views， letting doctors see 3D models of a patient’s body — like where a tumor (肿瘤) is — almost like giving them X⁃ray view.”可知，头戴设备通过展示患者身体的3D图像来辅助医生做手术。 6.What is one of the benefits of using VR for doctors? A.It allows them to perform surgeries without any help. B.It reduces physical stress and potential job⁃related pain. C.It enables them to communicate directly with patients. D.It allows them to work without any medical images. √ 解析:细节理解题。根据第三段中“In the past ...right in front of their eyes.”可知，使用虚拟现实技术给医生带来的其中一个好处是它减轻了身体压力和潜在的职业相关疼痛。 7.What is Broderick’s attitude toward VR’s future in healthcare? A.Negative.　　　　　 B.Neutral. C.Positive. D.Doubtful. √ 解析:观点态度题。根据最后一段中“Though the equipment ...‘This ... help millions get better treatment.’”可推知，Broderick对虚拟现实技术在医疗保健领域的未来持积极态度。 8.What can be a suitable title for the text? A.What Is the Future of VR in Hospitals? B.How Is VR Changing the World of Surgery? C.What Are the Challenges of VR in Hospitals? D.Why Is VR Technology Important for Patients? √ 解析:标题归纳题。通读全文，尤其是根据第一段可知，本文主要讲述了虚拟现实技术如何改变手术世界，B选项“How Is VR Changing the World of Surgery? (虚拟现实技术如何改变手术世界?)”最适合作为文章标题。 Ⅱ.阅读七选五 Simple Health Habits Worth Adopting Into Your Life We get it that it’s hard to break bad habits. But when it comes to building healthy habits， small decisions add up over time. Use stairs. If you have stairs at your home or office， take them every chance you get. 　9　 For a strong cardio (有氧) workout， you can walk up and down the stairs repeatedly. Start with a limited number of repetitions and then increase them as you feel stronger.  Drink one extra glass of water a day. It’s nothing new that there are health benefits to drinking more water. 　10　 If plain water isn’t your favorite， you can add flavor to your water to help increase your intake.  Correct your posture. When you were a kid， have your parents ever yelled at you for having bad posture? Well， the bad news is that they were right. 　11　 Not only that， but good posture prevents backache. You can try to leave yourself a note to sit up straight until it becomes an unconscious habit. Walking with your shoulders back and head held high can also make you feel good about yourself.  　12　 Solid sleep doesn’t just give you more energy， it can also help with healthy eating goals. If you have difficulty falling asleep， try to head to bed thirty minutes earlier than your usual time. Wind down with a book. You’ll be falling asleep in no time.  Remember that building new healthy habits can take some time and it’s OK to treat yourself to avoid feeling deprived (剥夺). Stay focused on your goal.　13　  A.However， don’t stop there. B.Change your bad sleep habits. C.Go to bed half an hour earlier. D.Having good posture can help reduce stress. E.It helps keep your temperature normal and gets rid of wastes. F.But we ignored their warning to correct bad posture. G.If you slip along the way， just start again. 语篇解读:本文是一篇说明文。文章介绍了一些在生活中要养成的好习惯，比如爬楼梯、多喝水以及早点休息等。 9.选A　上文“Use stairs ... you get.”和下文“For a strong ... repeatedly.”建议找机会爬楼梯进行锻炼，并且可以反复爬楼。选项A承上启下，转折上文语义，表示“只是有机会爬楼梯还不够，需要反复上下楼”。 10.选E　上文“It’s nothing new ... water.”说明多喝水有益于健康，选项E承接上文，和上文存在因果关系。选项中It指drinking more water。 11.选D　下文“Not only that ... backache.”描述良好的姿势的另一益处，选项D引起下文，说明保持良好姿势的益处。选项中good posture和下文词汇重叠，语义一致，故选D项。 12.选C　下文“Solid sleep ... time.”说明睡眠的好处并建议人们提前半小时上床睡觉，选项C能概括本段主题。 13.选G　上文“Stay focused on your goal. ”强调专注于自己的目标，选项G承接上文，表示一旦失败，就重新开始。 本课结束 $
