Sort of. My husband and I were recently in Egypt, where the temperature reached 113 degrees Fahrenheit, a bit warm for my tiny princess-like self.Medic, medic! So, we left Egypt.Back home, my dearest friends struggled with health stuff, with family craziness, with damaged children. The game of life is hard, and a lot of us are playing hurt.I ache for the world but naturally I'm mostly watching the Me movie, where balance and strength are beginning to fail.What can we do as the creaking (嘎吱作响的) elevators of age slowly descend? The main solution is to get outside every day, ideally with friends.Old friends—even thoughts of them—are my comfort. Recently I was walking along a beach with Neshama.We go back 50 years.She is 84, short but strong.Every so often, she bent down somewhat tentatively and picked up small items into a small cloth bag.“What are you doing？”“I'm picking up micro litter.I try to help where I can.” She reminded me of an old story.A great warhorse comes upon a tiny sparrow lying on its back with its feet in the air, eyes tightly shut with effort.The horse asks it what it's doing.“I'm trying to help hold back the darkness.”The horse roars with laughter.“That is so funny.How much do you weigh？”And the sparrow replies，“One does what one can.”This is what older age means：we do what we can. We continued our walk.Neshama bent to pick up bits of litter and started to slip, but I caught her and we laughed.We are so physically vulnerable in older age.We have caught each other a lot and have come through some periods of darkness and overwhelming losses, but friendship makes it all a rowing machine for the soul.We can take it as long as we feel and give love, and laugh gently at ourselves as we fall apart.We know by a certain age the great lies in our life—if you do or achieve this or that, you will be happy and rich.No.Love and service make us rich. 【语篇解读】　本文是一篇夹叙夹议文。文章主要讲述了作者和丈夫在埃及的经历、与老朋友在海滩上散步的情景，以及通过讲述马和麻雀的故事来表达自己对生活、友情、年龄和努力的看法，强调友情、爱和服务的力量超越物质追求。 1．What does the author think of her present life? A．She enjoys making new friends. B．She feels more struggles over the aging process. C．She finds it challenging to handle family crises. D．She wants others to learn from her life experiences. 细节理解题。根据第三段中的“The game of life is hard, and a lot of us are playing hurt...balance and strength are beginning to fail.What can we do as the creaking(嘎吱作响的) elevators of age slowly descend？”可知，作者觉得生活艰难，随着年龄增长面临诸多困扰。故选B。 √ 2．What message does the story of the sparrow convey? A．Age makes small efforts less meaningful over time. B．Strength in numbers is necessary to change the world. C．Even the smallest action will contribute to a bigger result. D．Every small action counts，no matter how insignificant it seems. 推理判断题。根据倒数第二段中的“And the sparrow replies，‘One does what one can.’This is what older age means：we do what we can .”可推知，提到麻雀的故事意在传达对于麻雀的行为的赞同：做自己能做的。也就是说，每一个小行动都很重要，不管它看起来多么微不足道。故选D。 √ 3．Which of the following can best describe Neshama? A．Healthy and cautious. B．Caring and responsible. C．Cooperative and modest. D．Educated and committed. 推理判断题。根据第四段中的“She is 84...picked up small items into a small cloth bag...‘I'm picking up micro litter.I try to help where I can.’”可知，84岁的Neshama 会去捡微小的垃圾，尽力在自己能做到的地方提供帮助，这体现了她关心环境、有责任感、乐于奉献的品质。故选B。 √ 4．What does the author suggest about the meaning of life in older age? A．Love and acts of service bring true richness in life. B．Happiness is achieved through love，rather than wealth. C．Health and independence are definitely the ultimate goals. D．True richness comes from love，service and achievements. 推理判断题。根据最后一段中的“We know by a certain age the great lies in our life—if you do or achieve this or that, you will be happy and rich.No.Love and service make us rich.”可知，作者认为到了一定的年龄，我们就会知道生活中巨大的谎言——如果你做到了或实现了这个或那个，你就会快乐和富有。不。爱和服务使我们富有。所以，作者认为晚年生活的意义不是物质上的实现，而是通过爱和服务的行为来丰富生活。故选A。 √ B It might surprise you to learn that dogs are playing an increasingly important role as conservationists.For centuries, they have been known as man's best friends.Now, their unique abilities are being made use of to help protect some of the world's most threatened species. Quick and loyal, dogs possess many qualities that make them ideal for fieldwork, but it's their extraordinary sense of smell that makes them invaluable for conservation work.With around 220 million olfactory receptors(嗅觉受体) compared to just 5 million in humans, dogs can detect scents(气味) and analyze them with astonishing accuracy, devoting 40 times more of brain to scent analysis than we do. Thanks to this incredible ability, some dogs are now being trained to save at-risk animals by sniffing(嗅)out their droppings.At the University of Washington's Conservation Canines facility，20 specially trained dogs have successfully tracked killer whale droppings, which only float briefly on the ocean's surface.Analyzing these samples enables scientists to monitor the health of killer whale populations, which are under significant stress from food shortages, pollution, and boat traffic. Beyond tracking animal droppings, conservation dogs are also trained for live animal detection, further showcasing their abilities.They can locate rare species in their natural habitats.Additionally, they are now used to tackle the non-native species that threaten the survival of the local wildlife.Dogs also take on other important roles.For example, at Kenya's Mombasa Port, dogs sniff out illegal wildlife products such as rhino horns and ivory.Across Africa, they work on the frontlines against illegal hunting, serving as a powerful security force enhancer. While dogs may not be the ultimate solution every conservation challenge, their incomparable abilities make them invaluable companions in the fight to protect our planet's biodiversity. 【语篇解读】　本文是一篇说明文。主要介绍的是狗凭借其卓越的嗅觉能力，在保护濒危物种、打击非法野生动物交易等方面发挥重要作用，成为生态保护的宝贵助手。 5．Why are the figures mentioned in the second paragraph? A．To highlight the superiority of dogs' sense of smell. B．To suggest the amazing accuracy of dogs' analysis. C．To recognize the importance of conservation work. D．To show dogs' impressive achievements in fieldwork. 推理判断题。第二段最后一句提到狗拥有大约2.2亿个嗅觉受体，而人类仅有500万个，狗能以惊人的准确性检测和分析气味，它们用于气味分析的脑力是人类的40倍。由此可知，本段以具体的数字来比较狗和人类的嗅觉能力，以此突出狗的嗅觉能力远超人类。故选A。 √ 6．How do dogs help protect killer whales? A．By tracking their movements. B．By detecting their droppings. C．By monitoring their populations. D．By analyzing the collected samples. 细节理解题。根据第三段中的“20 specially trained dogs have successfully tracked killer whale droppings...Analyzing these samples enables scientists to monitor the health of killer whale populations”可知，20只被特别训练的狗已经成功追踪到了虎鲸的粪便，分析这些样本使科学家能够监测虎鲸种群的健康状况。由此可知，狗通过嗅探虎鲸的粪便帮助保护虎鲸。故选B。 √ 7．What can we learn from the example given in paragraph 4? A．Wildlife products are popular in African countries. B．Non-native species affect the survival of local wildlife. C．Dogs are used to detect and prevent illegal wildlife trade. D．Dogs can accurately locate the natural habitats of rare species. 细节理解题。根据第四段中的“For example, at Kenya's Mombasa Port...serving as a powerful security force enhancer.”可知，以狗嗅出犀牛角和象牙等为例，提出狗狗在整个非洲都在打击非法狩猎的第一线工作，充当强大的安保力量，说明狗在打击非法野生动物交易方面的作用。故选C。 √ 8．What is the author's purpose in writing the text? A．To appeal to people to protect biodiversity. B．To report various environmental challenges. C．To introduce dogs' roles in conservation efforts.
