《月之精灵——蟾蜍》阅读练习及答案(2017年山东省济南市中考题)

阅读下面的文章，完成15—18题。（共1 2分）

（一）月之精灵——蟾蜍

①在我国古代，蟾蜍很早就跟月亮联系在一起。汉代的月神画像砖中，通常都趴着一只蟾蜍。就连发明地动仪的张衡在著述中都说：“羿请不死药于西王母，妲娥窃之以奔月……妲娥遂托身于月，是为蟾蜍。”两汉有关月亮的众多图画和文献，也都描述了这一神话，难怪古人把蟾蜍称为“月之精灵”。

②不论是神话传说中的蟾蜍，还是现实生活中的蟾蜍，都确确实实与人类有密切的关系。

③现实生活中的蟾蜍，身体表面有许多疙瘩，内有毒腺，能分泌黏液，又俗称“癞蛤蟆”。

④蟾蜍虽然容颜丑陋，却是自然界中的生存高手。它常常在早晨、黄昏或暴雨过后，出现在道旁或草地上。蟾蜍的皮肤柔软、潮湿、黏滑，含有丰富的毛细血管，而且它的皮肤较厚，具有防止体内水分过度蒸发和散失的作用，能长久居住在陆地上，而不到水里去。每当冬季到来，蟾蜍便潜入烂泥，用发达的后肢掘土，在洞穴内冬眠。三月初，当北方大地乍暖还寒，温度回升到10℃左右，它便从冬眠中苏醒。蟾蜍一般在清明前后产卵，一只雌蟾每次产卵3000～5000枚。

⑤蟾蜍行动笨拙蹒跚，不善游泳。由于后肢较短，只能做小距离的、一般不超过20厘米的跳动。如被人们用脚碰一下，它会立即装死，躺着一动不动。

⑥蟾蜍种类繁多，分布广泛。常见的蟾蜍，只不过拳头大小。可是南美热带地区，却生活着世界上最大的蟾蜍，个体长约2 5厘米，为蟾中之王，而有些小型的非洲蟾蜍的身长只有其1／10。

⑦蟾蜍是农作物害虫的天敌。它平时栖息在小河、池塘的岸边草丛内或石块间，白天藏匿在洞穴中不活动，清晨或夜间爬出来捕食昆虫、蜗牛等小动物。据科学家们观察研究，在消灭农作物害虫方面，蟾蜍要胜过漂亮的青蛙。它一夜吃掉的害虫，要比青蛙多好几倍。

⑧蟾蜍还是一种药用价值很高的动物。中国第一部药学专著《神农本草经》就记有蟾蜍的性味、归经和主治等方面内容。蟾蜍全身是宝，蟾酥、干蟾皮、蟾衣、蟾头、蟾舌、蟾肝、蟾胆等均为名贵药材，对慢性肝病、多种癌症、慢性气管炎、腹水、疗毒痈疽等有较好的疗效。

⑨尽管许多人对蟾蜍的外形没啥好印象，然

而。蟾蜍挺着大肚子，一次产卵数千枚，早在石器时代就被视为孕育生命、子孙昌盛的图腾。蟾蜍日伏夜出，与月亮同步出现，而月亮又与女子、婚姻、繁衍密切相关，所以蟾蜍成了月亮的形象大使。历代文人都常用“蟾宫”指代月亮。民间还用“蟾官折桂”来指代应考得中，甚至有人把砚台雕刻成蟾蜍形象，以求吉利。唐宋之后，月宫里的蟾蜍逐渐被人冷落，而口吐铜钱的“金蟾”却在民间日渐红火，形成了“家有金蟾，财源绵绵”的说法。民间画家在年画中也多以“金蟾”为题材，创作了“刘海戏金蟾”等作品，寓意财源广进，大富大贵。

⑩“鲛室影寒珠有泪，蟾宫风散桂飘香。”蟾蜍及其承载的传统文化，在科学技术发达的今天，仍然散发着无穷的魅力。

15．文章以“月之精灵——蟾蜍”为题目，有什么作用？（3分）

【答案】题目点明了文章说明的对象——蟾蜍，同时把“蟾蜍”比作“月之精灵”，引起了读者的阅读兴趣。

【解析】本题考查文章题目的作用。通常来讲，文章题目的作用主要有：①概括文章的主要内容；②作为文章线索（文章情节围绕这一线索展开）；③作者感情的出发点；④具有象征意义；⑤语带双关；⑥全文的“文眼”（提示文章中心）；⑦吸引读者兴趣。本文主要

介绍了两部分内容，一是从外形、种类、动作、价值等方面介绍了蟾蜍，二是阐述了蟾蜍和中国传统文化的联系。两部分内容都围绕说明主体“蟾蜍”展开。另外用“月之精灵”来修饰“蟾蜍”，看似很不搭，却引起了读者的阅读兴趣。

16．阅读全文，在第⑨段横线处填写一个能概括下文的句子，使上下文语意连贯。（3分）尽管许多人对蟾蜍的外形没啥好印象，然

而。【答案】示例：在中国文化中它却有着许多美好的寓意（或“蟾蜍却是中华文化的承载者”）【解析】本题考查对重点句子的理解与补写。第⑨段中“尽管很多人对蟾蜍的外形没啥好印象”是承接上文的句子，因此横线处应当补写与下文紧密相连的句子。第⑨段主要介绍了蟾蜍与中国传统文化的联系（蟾蜍在中国传统文化里的美好寓意），围绕这个话题补写即可。

17．文章第⑥段画线句运用了三种说明方法，任选其中一种，简要分析表达作用。（3分）【答案】示例一：列数字。“个体长约25厘米”使我们对“最大的蟾蜍”有了量化和具体化的认识，使说明更加直观生动，增强了文章的说服力。

示例二：作比较。“小型的非洲蟾蜍的身长只有其1/10”是将“小型的非洲蟾蜍”和“最大的蟾蜍”的体型作比较，从而突出“最大的蟾蜍”的体型之大，使说明更加生动，增强了文章的说服力。

【解析】本题考查说明方法及其作用。常见的说明方法有：下定义、举例子、列数字、打比方、作比较、作引用、分类别、摹状貌。解答本题，可根据文章中的具体句子分析其运用的说明方法。例如，文中“个体长约25厘米”是列数字的标志性特征，通过这个数据，我们很容易了解到“最大的蟾蜍”的体型，使我们对该种类蟾蜍有了具体而形象的了解。18．阅读第⑦段，分析下面句中加点词语的表达作用。（3分）

它平时栖息在小河、池塘的岸边草丛内或石块间，白天藏匿在洞穴中不活动，清晨或夜间爬出来捕食昆虫、蜗牛等小动物。

【答案】“平时”反映了蟾蜍的生活习性，是一般状况，并不排除其他状况的存在。充分体现了说明文语言的严密性和准确性。

【解析】本题考查说明文的语言特点。说明文语言的特点主要有：简洁性、准确性、科学性、严密性、条理性、逻辑性、趣味性。这些特点往往是通过重点词语、句子来体现的，文章第⑦段介绍了蟾蜍的生活习性，是一般性的，并不能将所有的状况一一罗列，这里的“平时”一词就体现了说明文语言的严密性和准确性。

中考英语英语阅读理解练习题(及答案) 一、英语阅读理解专项练习试卷 1．阅读理解 According to a 2018 study from San Francisco State University, nearly 2. 4 billion people around the world used a smartphone in 2017. By the end of 2019, more than a third of the global population will be using a smartphone. However, smartphone technology can be a double-edged sword. On the one hand, it sends us unlimited amounts of information. On the other hand, using a smartphone may become an addiction. Erik Peper and Richard Harvey are both health education professors at San Francisco State university. They led the study. Peper explains that smartphone addiction forms connections in the brain that are similar to drug addiction. And these connections form slowly over time. Also, addiction to social media may affect our emotional state. The two professors asked 135 university students about their habit of smartphone use and their feelings. They found that students who used their phones the most reported higher levels of feeling lonely, depressed and anxious. Peper and Harvey do not blame users for their technology addiction. They believe it is the tech industry's desire to make more money that is to blame for the technology addiction. The researchers warm that workers in the technology industry know how to control our brains and turn us into addicts. But the researchers say that we can limit our brains to be less addicted to our phones and computers. Enk Peper suggests timing off our phones before we sleep or do something important. The researchers also suggest taking control of when and where you answer texts or emails. You do not need to answer them all. And you certainly don't need to answer them as soon as you get them. They also suggest putting limits on the time you spend on social media. If you want to catch up with friends on Facebook, set aside a small amount of time to it. You should focus on important tasks and do not allow technology to disturb you. （1）What can we infer from Paragraph 1? A. Smartphone use has become extremely common. B. Most young people can't live without smartphones. C. Smartphones make our life more colorful and convenient. D. Most people consider smartphones as the greatest invention. （2）The underlined sentence in Paragraph 2 means smartphone technology____. A. has a brilliant future B. can be better than most people think C. has both advantages and disadvantages D. can give us unlimited amounts of information （3）What did Enk Peper and Richard Harvey find about smartphone use? A. It can help reduce loneliness. B. It's more popular with students.

最新中考英语英语阅读理解试题(及答案) 一、英语阅读理解专项练习试卷 1．阅读理解 That cold January night, I was growing sick of my life in San Francisco. There I was, walking home at one in the morning after a tiring practice at the theatre. With opening night only a week away, I was still learning my lines. I was having trouble dealing with my part-time job at the bank and my acting at night at the same time. As I walked, I thought seriously about giving up both acting and San Francisco. City life had become too much for me. As I walked down empty streets under tall buildings, I felt very small and cold. I began running, both to keep warm and to keep away from any possible robbers (抢劫犯). Very few people were still out except a few sad-looking homeless people under blankets. About a block from my apartment (公寓房间), I heard a sound behind me. I turned quickly, half expecting to see someone with a knife or a gun. The street was empty. All I saw was a shining street-light. Still, the noise had made me nervous, so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize what the noise had been. It had been my wallet falling to the street. Suddenly I wasn't cold or tired any more, and I ran out of the door and back to where I'd heard the noise. Although I searched the street anxiously for fifteen minutes, my wallet was nowhere to be found. Just as I was about to give up the search, I heard the garbage truck (垃圾车) pull up to the street next to me. When a voice called from the inside, "Alisa Camacho?" I thought I was dreaming. How could this man know my name? The door opened, and out jumped a small red-haired man with an amused look in his eyes. "Is this what you're looking for?" he asked, holding up a small square shape. It was nearly 3 a.m. by the time I got into bed. I wouldn't get much sleep that night, but I had got my wallet back. I also had got back some enjoyment of city life. I realized that the city couldn't be a bad place as long as people were willing to help each other. （1）How did the writer feel when she was walking home after work? A. Cold and sick. B. Fortunate and helpful. C. Disappointed and helpless. D. Satisfied and cheerful. （2）From the first paragraph, we learn that the writer was busy _________. A. solving her problem at the bank B. preparing for the first night show C. learning acting in an evening school D. taking part in various city activities （3）On her way home the writer __________. A. lost her wallet unknowingly B. was stopped by a garbage truck driver C. was robbed of her wallet by an armed man D. found some homeless people following her （4）In the fifth paragraph, why did the writer say she was dreaming? A. Someone offered to take her back home. B. A red-haired man came to see her. C. Her wallet was found in a garbage truck. D. She heard someone call her name. （5）From the text, we can infer that the writer _________.

2017年中考物理专题《开放类型题》 【题型概述】 题型特征:所谓开放性试题，即把题目的封闭性问题变为开放性问题，其开放可能在于条件、结论、解法，也可能在于问题的设问角度、方式的变化，有的问题答案也不唯一从试题的内容来分类，又可分为情景信息开放题、综合计算开放题和实验开放题，它涉及面广，在填空、探究、计算、作图中都会出现. 此类试题选取的材料一般都是常见的，但角度翻新，重在考查学生综合探究和创新设计的能力，百花齐放，使得学生的个性得到了张扬，从而实现了思维的创新. 解题策略:解答此类题目时，思维要不拘一格，从所给出的信息中尽可能扩展、朝各个方向去探寻各种不同的解决途径和答案.挖掘题目中的隐含条件是解答这类试题的关键，对问题要从不同角度进行探索，从不同层面上进行分析，从正反两极进行比较，要克服思维定式，避免思维僵化及单一另外，由于开放题的难度与题中所提供的情景和学生所熟悉程度有关，因此在日常生活中一定要做有心人，注意观察身边的各种物理现象，思考各种现象之间涉及的物理知识，加深对物理概念、规律的理解. 【真题精讲】 类型一提问型开放性题 典例1.如图所示是用来演示惯性小实验的示意图，请你根据所观察到的现象提出两个问题，并用所学的物理知识加以解释. 示例:弹片为什么会弯曲? 力可以使物体的形状发生改变. 【解析】(1)弹性钢片在力的作用下发生弯曲，说明:力可以使物体发生形变; (2)由于小砝码具有惯性，要保持原来的静止状态，所以小砝码不会随小木片飞出. (3)弹性钢片打击小木片时，小木片受到力的作用，在力的作用下小木片飞出去，小木片的运动状态发生改变，这说明:力可以改变物体的运动状态. (4)飞出去的小木片在运动过程中受到竖直向下的重力作用，小木片下落. (5)弹性钢片将小木片弹走时，弹性钢片的弹性势能转化为小木片的动能. 【答案】1.纸片为什么会向前运动?力可以改变物体的运动状态. 2. 砝码为什么落在原处?因为砝码具有惯性. 1. 如图所示是女排运动员打排球拦网时的场景.请你从力学角度提出一个问题并回答.

【英语】中考英语阅读理解测试题及答案经典 一、初三英语阅读理解（含答案详细解析） 1．阅读理解 Radio and television are very popular in the world today. Millions of people watch TV. Perhaps more people listen to the radio.

2017年中考英语解析版试卷精选汇编--阅读理解之环保问题

环境保护 (2017·浙江衢州)D Heritage(遗产)is traditional customs, culture and beliefs(信仰). We use the world “heritage”in many different ways. People talk about their family heritage, their city’s heritage, and their country’s heritage. Today, heritage is changing. The Internet connects people around the world. In many ways this is a good thing, because we can learn about the heritage of other countries, and we can show our own heritage to the world. However, some people worry that traditional heritage is disappearing. Think about it. In many ways, countries are becoming more and more alike(相似的). In just about every country around the world, you can find MacDonald’s, Nike Shoes, Starbucks coffee, and American movies. Some people think this is a good change, and others don’t like it. You can decide whether or not you think it’s a good thing. However, everyone wants to protect their traditional heritage, and sometimes this is hard. For example, when a new MacDonald’s opens in your town, a traditional restaurant might have to close. This is why heritage protection is so important. Heritage protection is a simple idea. It means keeping your country’s or your city’s heritage alive. People do this in many ways. The biggest part of heritage protection is probably preserving(保护)old buildings. A few other examples of heritage protection are making sure your children speak your traditional language, and teaching your heritage to children. The world is changing very fast. This change brings a lot of good things. But as the world is changing, it is important to remember the heritage of our parents and our grandparents. 42.
