专题06 任务型阅读

2019

请阅读下面短文，根据短文内容，在下面的表格中填入与文章意思最符合的单词，

并写在答题卡相应位置上。每空一词

As the proverb says, “Your tongue has the power of life and death.” This means that your words have power to finally cause things to happen, even life or death.

We may all experience the power of words in our life, even when we were very young. A child is blamed ( 责备 ) by teachers or parents, and after that, he might probably think of himself as a bad child. Most kids have that experience. They say it is important to praise children four times for each negative ( 负面的 ) word. Blaming will make things worse, while positive words are helpful especially when being in trouble or in need. When we fail the exam, encouraging words from our teachers or parents make us work harder at our lessons. Encouraging words can go quite a long way. They lift people up. For example, encouraging words to someone who is sad can help them make it through the day. Words can have a powerful effect on your brain. And it will in turn ( 相应地 ) have a great influence on your action.

Everything you do depends on what you choose to do. It’s not your parents, your past relationships or your job, but you and only you that are responsible for every goal you set. If you have dreams in life, write them down and speak them out. Your words are likely to bring you out something amazing.

action____42____.

____43____you make.

【答案】pass

【解析】由原文第二段中When we fail the exam, encouraging words from our teachers or parents make us work harder at our lessons.可知，不能通过考试的孩子，应鼓励他们，使他们更加努力地学习。fail the exam=can’t pass the exam ，是同义转换。故这里填pass，意为“通过”。

43.

【答案】choice/choices

【解析】由原文第三段 Everything you do depends on what you choose to do. 可知，这里应表示“你的选择”，原文是choose 动词，这里应转换为名词，故填choice/choices。

its popularity has risen around the world. Many countries set up Chinese courses in their schools.

For example, in the UK, students used to choose between Spanish, Latin, French and other foreign languages. But now schools encourage their students to study Chinese. The increase in popularity of Chinese has been surprising. 1031 people took Chinese language exams in 2001, and the number was 2062 last year, while 2561 people chose Spanish. It's predicted that studying Chinese in the UK could overtake (超过) Spanish in less than five years.

Just like the foreigners do, we also learn foreign languages. Different languages carry different cultures. So exchanges are necessary. By learning a foreign language, we not only have a useful tool

of communicating, but experience a new culture, what's more important, learning a foreign language well

will help us tell our own stories to the world.

【答案】Because they have to memorize a large number of characters./ Because Chinese characters are not easy to write./ Because the same word has different meaningin different sentences./ Because they have difficulties in reading poems.(答出其中一条即可)。

【解析】根据短文第一段中The Chinese use a different character( 汉字 ) for each word. People have to memorize about 600 characters before they can do even basic reading and writing. For foreigners, it's hard to memorize them.可知，外国人觉得汉语难学，其中一个原因是他们要记住大量的汉字。短文中的表格中也列出了一些其他的困难，如写汉字、不同句子中汉字的意思不同以及读汉语诗歌的困难等等。故答案为Because they have to memorize a large number of characters./ Because Chinese characters are not easy to write./ Because the same word has different meaningin different sentences./ Because they have difficulties in reading poems.

It's predicted that studying Chinese in the UK could overtake (超过) Spanish in less than five years.可知，2001年参加汉语考试的有1031人，去年参加的有2012人，多了1031人。这说明越来越多的英国人学习汉语，汉语在英国变得越来越受欢迎。故回答1031. (It tells us) the increase in popularity of Chinese is surprising in the UK./ Chinese is becoming more and more popular in the UK.

49.

【答案】We / I can tell our own stories to the world./ We/ I can spread colorful Chinese culture to the world. / We/ I can teach foreign people Chinese./ We/ I can have more chances to find a good job.

【解析】短文的最后By learning a foreign language, we not only have a useful tool of communicating, but experience a new culture, what's more important, learning a foreign language well will help us tell our own stories to the world.这几句话讲述了学习外语的作用，学生们也可以根据实际情况回答，符合情理即可。如We / I can tell our own stories to the world./ We/ I can spread colorful Chinese culture to the world. /

Since dogs are considered to have many good qualities ( 品质), the word is included in more than 10 Chinese metaphors. For example, “serve like a dog or a horse,” is used to describe someone who is ready to work hard for the people

64.

【答案】easily

【解析】由 as...as 可知，该空考虑填形容词或副词的原形，又因为该空修饰 grow up，因此，考虑填副词。由原文第四段最后“they are as easy to be raised as dogs”可知，该空填 easily.

C、足球在水平地面上滚动一段距离时，移动距离的方向水平向前，重力的方向竖直向下；两个方向相互垂直，故重力对足球没有做功；故C错误； D、运动员从地面将杠铃举起的过程中，力的方向竖直向上，移动距离的方向也竖直向上，两个方向一致；故举重运动员对杠铃做功；故D正确； 故选：D。 3．（2018?盐城）小明将掉在地面上的物理书捡起来放在课桌上，他对课本所做功最接近于（）A．0.02J B．0.2J C．2J D．20J 【分析】首先估测物理课本的质量，然后计算它的重力，然后再估测课桌的高度，最后根据功的公式计算即可。 【解答】解：一本物理课本的质量m=200g=0.2kg， G=mg=0.2kg×10N/kg=2N， 课桌高度约为1m， 人对课本做的功：W=Gh=2N×1m=2J。 故选：C。 4．（2018?广州）如图所示，OQ是水平地面，物体在水平拉力作用下从O匀速直线运动到Q，OP段拉力F1为300N，F1做的功为W1，功率为P1；PQ段拉力F2为200N，F2做的功为W2，功率为P2．则（） A．W1＞W2 B．W1＜W2 C．P1＞P2 D．P1＜P2 【分析】（1）根据W=Fs分别计算F1和F2所做的功，然后比较即可； （2）根据P= = =Fv分析比较F1和F2所做的功的功率的大小。 【解答】解： （1）由图知，OP段的路程s1=4m，PQ段的路程s2=6m， OP段拉力F1做的功为：W1=F1s1=300N×4m=1200J，

2019年中考物理试题分类汇编——科普阅读题专题(word版包含答案)

2019年中考物理试题分类汇编——科普阅读题专题 1.(2019北京，33)请阅读《郭守敬望远镜》并回答问题 郭守敬望远镜 “星汉灿烂，若出其里”。漫天星光绝大多数都来自宇宙中的恒星。怎样知道这些遥远且炽热的恒星的成分呢？用光谱!我们知道，阳光通过三棱镜后会发生色散，形成一条按照一定顺序排列的彩色光带，我们称之为光谱。太阳是恒星，因此太阳的光谱是一种恒星光谱。恒星光谱包含了恒星的很多“户口”信息，比如化学成分、密度、气压、温度、恒星年龄等。恒星光谱除了包含恒星自身的信息之外，还能告诉我们恒星以及它所在的星系是在远离，还是在靠近我们，甚至还能告诉我们远离或靠近的速度有多大。观测表明，恒星或星系远离我们的速度与它跟我们之间的距离成正比，根据恒星或星系远离我们的速度可以知道这个恒星或星系距离我们有多远。 光谱望远镜是获取恒星光谱的有力工具。目前世界上最好的光谱望远镜是由中国天文学家自主研制的，以元代著名天文学家、数学家、水利工程专家郭守敬名字命名的“郭守敬望远镜”，如图所示，它可以将接收到的恒星的光会聚后通过色散系统形成恒星光谱，进而获取恒星的信息。它能够同时观测4000个天体，是当今世界上光谱获取效率最高的望远镜。在刚刚过去的七年巡天观测中（所谓“巡天观测”，就好比是“给天上的星星做‘人口’普查”），郭守敬望远镜共获取1125万条光谱，成为世界上第一个获取恒星光谱数突破千万量级的天文望远镜。我国科学家通过对这些恒星光谱的分析，绘制成了一个包含636万组恒星光谱参数的星表，重新确立了银河系晕（音yún）的内扁外圆的结构，并取得了其他一些令世界瞩目的重大发现，这在某种程度上增强了人类寻找另一个“地球”和地外生命的信心! 日前，郭守敬望远镜已开启新一轮的“霸气”巡天观测征程。使用郭守敬望远镜可以“普查”银河系更多的恒星，以它的观测能力，北半球天空仍然有约一亿颗星可观测，可以让“普查”

【答案】 B 【解析】【解答】杂技演员站在楼梯上处于静止状态，受到平衡力的作用，所受重力和支持力是一对平衡力，大小相等、方向相反、作用在同一直线上，重力的方向竖直向下，所以支持力的方向竖直向上，B符合题意，ACD不符合题意。 故答案为：B。 【分析】画力的示意图的一般步骤为：一画简图二定点，三画线，四画尖，五把力的符号标尖边. 3．下列说法错误的是（） A. 足球被踢出后仍继续向前运动，是因为它运动时产生惯性 B. 汽车在转弯时减速是为了防止惯性带来的危害 C. 闻到花香说明分子在不停地做无规则运动 D. 游泳时向后划水，人向前运动，是因为物体间力的作用是相互的 【答案】A 【解析】【解答】A、足球被踢出后仍继续向前运动，是因为它具有惯性，不能说“产生惯性”，A符合题意； B、惯性是物体保持原来的运动状态不变的性质，汽车在转弯时减速是为了防止惯性带来的危害，即防止车辆侧翻或侧滑，B不符合题意； C、闻到花香是扩散现象，是由分子在不停地做无规则运动而形成的，C不符合题意； D、游泳时向后划水，人向前运动，是因为物体间力的作用是相互的，即水会给人向前的力，使人前进，D不符合题意 . 故答案为：A . 【分析】A、惯性是物体的一种性质，物体无论运动还是静止都具有惯性，不是由于物体运动才产生的； B、汽车在转弯时减速是为了防止由于惯性车辆侧翻或侧滑； C、由分子在不停地做无规则运动，人们才能闻到花香； D、由于物体间力的作用是相互的，游泳时向后划水时，水给人一个向前的力，人向前运动 . 4．如图所示，放在水平桌面上的物块用细线通过定滑轮与沙桶相连，当沙桶与沙的总质量为m时，物块恰好做匀速直线运动（忽略细线与滑轮之间的摩擦）。以下说法正确的是（）
