For instance，almost all animals have distinct vocals (声音) that they rely on to either ask for help，scare away any dangerous animals or look for shelter. But cats are special creatures who possess amazing vocalization skills. They are able to have entire conversations with humans using meows and you're able to interpret it. If a pet cat is hungry，it will keep meowing to attract attention and find food. However，when a cat is looking for affection，they tend to produce stretched and soft meows. Meowing starts as soon as a baby cat is brought to life and uses it to get the mother's attention and be fed. Cats have many heightened senses，but their sense of smell is quite impressive. They use their noses to assess their environment and look out for any signs of danger. They will sniff out specific areas before they choose a place to relax. However，another way the cats are able to distinguish between situations is by looking for familiar smells. Your cat will likely smell your face and store the smell in its memory and use it to recognize you in the future. That's why most pet cats are able to tell immediately if their owners were around any other cats，which they don't usually like. Dogs are known for their impressive fetching habit，but cats take this behavior up a notch．Many cats will find random objects outside and bring them to their owners. This is a very old habit that's been present in all kinds of predators (食肉动物).Cats bring gifts for their owners to show they love you. These adorable little hunters are just doing something that it's been in their nature since the beginning of time. So just go along with it! 语篇解读　本文是一篇说明文。文章介绍了猫的生活习性，它们的叫声特别，能与人类交流，嗅觉敏锐，能识别主人，许多猫会将在外面找到的物品带给主人表达爱意。 1．What can be learned about cats' meowing from the first paragraph? A．It's a survival skill. B．It's taught by mother cats. C．It's hard to interpret. D．It's getting louder with age. 细节理解题。根据第一段中的“They are able to have entire conversations with humans using meows... to attract attention and find food.”和“Meowing starts as soon as a baby cat...be fed.”可知，猫用喵喵叫和人对话。如果一只宠物猫饿了，它会不停地喵喵叫以吸引注意力并找到食物。喵喵叫从小猫一出生就开始了，小猫用它来吸引猫妈妈的注意并被喂食。由此可知，喵喵叫是猫的生存技能。 √ 2．How does a pet cat assess different situations? A．By listening for sounds. B．By touching familiar objects. C．By checking on smells. D．By communicating with other cats. 推理判断题。根据第二段的“They use their noses to assess their environment and look out for any signs of danger...looking for familiar smells.”可知，猫用鼻子评估环境并留心任何危险迹象。它们能够区分不同环境的另一种方法是寻找熟悉的气味。由此可推知，猫通过检查气味来评估不同的环境。故选C。 √ 3．Which best explains the phrase “take this behavior up a notch” in paragraph 3? A．Perform appropriately.　　　 B．Move faster. C．Act strangely. 　 D．Do better. 词义猜测题。画线部分前提到狗以其令人印象深刻的取物习惯而闻名，下文介绍了猫的行为，它们会将在外面找到的物品带到主人身边以表达它们的爱意。由此可推知，与狗相比，猫更擅长“去取物品来表达对主人的喜爱”。故画线部分在此意为“做得更好”。故选D。 √ 4．What is a suitable title for the text? A．Tips on Finding a Smart Cat B．Understanding Your Cat's Behavior C．Have Fun with Your Cat D．How to Keep Your Cat Healthy 标题归纳题。通读全文可知，文章主要介绍了猫的行为和它们表达需求和情感的方式，旨在帮助人们更好地理解猫的行为。故B项“理解你的猫的行为”最适合作文章标题。 √ Ⅱ.完形填空(每小题1分，共15分) (2024·山东省高二上适应性联考) It was a turtle that changed Victoria Cairns，a headteacher from Derbyshire.She was 1 in Bali underwater when she saw one of the island's famous 2 ．It approached towards her in the crystal clear water，and she was 3 at first—until she saw the plastic bag in its mouth.She just thought the human was having a destroying 4 on the environment.
