七年级移项专项练习题（共7篇）
1.七年级移项专项练习题 篇一
移项是初中数学的重要知识点，因为它是解方程，求方程解的重要步骤。多年的教学实践经验告诉我，初一学生初次接触移项的相关知识始终存在以下两个问题：一是对概念的理解含混不清，始终把移项与加法算式中交换项的位置混淆;二是对移项要改变符号的法则非常清楚，就是往往在实际操作过程中，项倒是移了，却忘记了改变符号。针对这个问题，今年我在教学《移项》一课时做了一番思考，感觉效果不错，现将其陈述于后，以期与同行共勉。
二、教学过程设计
（一）课前准备
1.3—5个学生每人记住一个含有两个未知项、两个常数项的一元一次方程，比如类似于“3x-7+4x=6x-2”、“4-3x=3-2x”这样的方程，对不知道移项的学生来讲不算简单，但对老师来讲很简单，无需动笔就知道答案，并叮嘱学生到时将其写在黑板上。
2. 准备5张A4纸大小的卡片，其中两张用毛笔写上关于x的未知项(连同符号)，背面写上它的相反数，两张各写一个常数项，背面写上它们的相反数，剩下一张卡片画上“=”。
（二）上课过程
1. 情境创设。
师：同学们，我们上一节课学习了用等式的性质求解一元一次方程，大家感觉如何?
多数同学：比较困难(麻烦)。
师：我们现在做个游戏，任何一个同学只要随便写出一个一元一次方程在黑板上，老师可以不动笔，在2秒钟之内将它的解求出来。
部分同学：老师，你吹吧。
师：不信咱们试试?
生：好的。
师：哪位同学来写个方程在黑板上?(眼神示意先前叮嘱过的同学)
甲乙丙丁四个同学依次上台，老师一一快速说出其解。
部分同学：哇，老师，你太有才了。
师：老师有一种特异功能，不过这节课我们将要学习《移项》，只要大家把这节课学好了，你们就学会了老师的特异功能。你们想不想学这种特异功能?
同学们：想。
2. 同学们迅速浏览课文内容，找到两个问题的答案：
(1)什么叫移项?
(2)移项要注意什么问题?
3. 白板出示上述两个问题的答案。
4. 游戏。
五位同学各拿一张卡片于胸前，上台排成一个方程，如下图：
师：上面的某些同学将要发生位置的改变，同学们认真观察，这种改变叫不叫移项?如果是移项，移对没有?台上的同学注意，如果你的位置发生了改变，你手上拿的两张卡片(一正一负)，应该把哪张展示个大家?
师：1、2号同学对调;4号同学到等号左边去;1号到右边，5号到左边;2号到右边，4号到左边;3、4号同学对调……
上述过程，通过游戏的形式，将方程中的移项，与多项式中项的位置的交换做了鲜明对比，全班同学都积极参与其中。
例题：判断下列移项是否正确?
A.由5+3x=2, 得3x=2+5
B.由-10x-5=-2x, 得-10x-2x=5
C.由7x+9=4x-1, 得7x-4x=-1-9
D.由5x+2=9, 得5x=2+9
课堂剩余时间学生巩固练习，在此不详述。
三、教学反思
本堂课教学效果较好，从当堂检测的情况看，学生对什么是移项、移项时要改变符号已掌握得根深蒂固。全班50个同学只有2个同学在检测中出现了错误，这是在该班以前的教学中少有的现象，也是该内容在以前的教学中少有的现象，究其根源是课堂上两次学生活动的有效开展。
(一)游戏使得本堂课课堂气氛异常活跃。由于有老师的玩笑(自吹特异功能)、学生移动位置两张卡片的变与不变的纠结，让整堂课充满了笑声，同时笑声中带着对若干问题的思考，学生在轻松愉快的过程中学习了新知。初一学生的心理特点其实与小学生没什么本质区别，上课注意力难以持久，喜欢做游戏。我们的教学设计应该顺势而为，让学生轻松愉快地接受新知。

3.七年级移项专项练习题 篇三
《〈论语〉十则》
一、词语积累
（一）常规词语
[子]先生，指孔子。[时习]时常地复习。时，时常（又：按一定时间）。习，温习、复习、实习。[朋]同门，这里指志同道合的人。[亦]也。[自]从。[（不）知]（不）了解。[愠（yùn）]生气，发怒。[君子]指高尚的人。[吾]我。[日]每天。[三省（xǐng）]多次进行自我检查、反省。三，泛指多次。省，反省。[为（wèi）]替，给。[谋]谋划，指办事。[忠]尽心竭力。[交]结交，交往。[信]真诚，诚实。[传]老师传授的知识。
[故]指学过的知识。[罔（wǎng）]迷惑。意思是感到迷惑而无所适从。[殆（dài）]有害。[诲（huì）]教，教导。[知（之）]知道（它）。[是]此，这。[贤]贤人，有才德的人。[齐]看齐，一齐。[内]指内心。[善者]指长处。善，好。[从]跟从，这里指学习。[士]士人，封建时代称读书人。这里指有抱负或有特殊地位的人。[弘（hóng）毅]刚强，勇毅。[任]负担，担子。引申为责任、职责。[重]重大。[已]停止。[岁寒]寒冷的冬天。岁，指时间。[凋(diāo)]凋谢。[行]奉行。[其]大概。[恕（shù）]指儒家的推己及人，仁爱待人。[欲] 想，希望。[勿（wù）]不要。[施]加。
（二）通假字、古今字
1.通假字：[女]同“汝”，你。[（是）知（也）]通“智”，聪明、智慧。
2.古今字：[说]“悦”的古字，愉快。
（三）成语
[不亦乐乎] 愿意是“不也很快乐吗？”现用来表示达到极点的意思。
[温故知新] 温习旧的知识，能够得到新的理解和体会。也指回忆过去，认识现在。
[己所不欲，勿施于人]自己不愿意的，不要加给别人。
[任重道远]担子很重，路程遥远。比喻责任重大，要经历长期的奋斗。
[见贤思齐]看到德才兼备的人，就想向他学习，和他一样。
[择善而从]选择好的学，按照好的做。
[三人行，必有我师]几个人在一起走路，其中必定有我的老师。形容谦虚好学。
二、文学常识
1.《论语》：记录孔子和他的弟子言行的书，共20篇，是儒家经典著作之一。
2.孔子：名丘，字仲尼，春秋时鲁国人。我国古代伟大的思想家、教育家，儒家学派的创始人。
三、阅读探究
1.第一则：
（1）这一则告诉我们要有怎样的学习方法、学习乐趣（态度）和为人态度（个人修养）？
①学习方法：学后要时常复习。②学习乐趣：志同道合的人从远方来探讨学问。③为人态度：对不了解自己的人，毫不怨恨。
（2）学后复习本是一件艰苦的事，孔子怎么说是愉快呢？
在复习中巩固了所学，加深了理解，收获增多，这对一个渴求知识和技能的人来说一定是愉快的。
（3）“有朋自远方来”，孔子为什么会感到快乐？
志同道合的人从远方来投奔自己，向自己学习，且双方可以探究学问，这自然是十分快乐的事情。
（4）从第三句来看，我们应学习孔子什么美德？
胸怀宽广，为人大度。
2.第二则：
从曾子“三省”来看，古代治学之人非常重视的是什么？你怎样看待这种做法？ 重视品德修养。德乃为人之本，治学之基。一个人首先应该有德，有才无德，其人会遭人鄙视，其才也不会起到积极的作用，却会引起消极的影响。
3.第三则：
（1）“温故”和“知新”是否是并列关系？作者强调了什么？为什么？
不是。强调独立思考的必要性。孔子说：“记问之学不足以为人师”；一定要将知识融会贯通，能在复习旧知识中有所发现，才 “可以为师”。所以，关键是要“知新”，这就要独立思考。
（2）“温故知新”的学习方法对你有怎样的启发？
在学习中要及时温习旧知识，通过独立思考，获得新的理解和体会，有新发现，从而将知识融会贯通，增长自己的能力。
4.第四则：
（1）这一则阐述了怎样的内容？你从中掌握了什么学习方法？
阐述了学习与思考的辩证关系。告诉我们要学思结合，二者不可偏废。
（2）为什么要将学习和思考结合起来？
学是基础，只学不思，是死学；只思不学，是空想。只有将二者结合，才能真正领悟知识的精髓。
5．第六则：
（！）孔子教育仲由（子路）“知之为知之，不知为不知”，用现代汉语概括孔子的观点。
要有谦虚的学习态度。
（2）为什么说谦虚是一种智慧？
首先，谦虚是一种美德。其次，只有谦虚，才能赢得他人的信任和尊重，为求知和交往等创造良好的条件。
6.第六则、第七则：
（1）这两则讲了怎样的学习态度？
要善于向一切人学习。既要学习长处，又要借鉴短处，从而反省自己。
（2）用一个成语概括第七则的主要意思。
取长补短。
（3）唐太宗李世民有句名言：“以人为鉴，可以明得失。”你能联想到孔子的哪句话？
择其善者而从之，其不善者而改之。
7.第八则：
（1）孔子说这番话的目的是什么？
鼓励门人一生为实现“仁”的理想而奋斗。（“仁”是孔子思想的核心。）
（2）曾子为什么要强调“弘毅”？
“弘毅”是刚强、勇毅的意思，只有刚强、勇毅才能接受重任并为之奋斗。
8.第九则：
怎样理解“岁寒，然后知松柏之后凋也”这句话的深刻含义？
孔子借“松柏之后凋”比喻社会现象，以“松柏”比喻君子。只有在险恶环境下，才能显示出君子的操守。
9.第十则：
（1）“恕”与“己所不欲，勿施于人”是什么关系？
“己所不欲，勿施于人”是对“恕”的诠释。
（2）你怎样看待“己所不欲，勿施于人”这一观点？
这句话现在看来，有其现实意义。其中包含相互体谅的意思。遇事如果换位思考，推己及人，仁爱待人，就可能得出不同的结论，改变已有的不正确做法，这样就会多一分理解，少一分对立，避免对他人造成伤害。
（也可谈其消极成分，略。）
四、总结迁移
1.请按照学习方法、学习态度、品德修养给十则语录归类。
①学习方法：学而时习之温故而知新学而不思则罔，思而不学则殆
②学习态度：有朋自远方来知之为知之，不知为不知见贤思齐三人行，必有我师择其善者而从之，其不善者而改之
③品德修养：人不知而不愠吾日三省吾身士不可以不弘毅己所不欲，勿施于人岁寒，然后知松柏之后凋
2.新学期又开始了，我校要迎来一批新同学，请你从本文中为学校选择一句话制成欢迎横幅。
有朋自远方来，不亦乐乎？
3.《论语》中含有大量的成语，请再从《论语》中挑选出几个本文外的成语。不耻下问学而不厌诲人不倦
4.又要重新布置班级了，请在本文中选择几条格言，书写成条幅，挂在班级墙壁上。
①学而时习之，不亦悦乎？②温故而知新，可以为师矣。③学而不思则罔，思而不学则殆。④知之为知之，不知为不知，是知也。⑤见贤思齐焉，见不贤而内自省也。⑥三人行，必有我师焉。⑦士不可以不弘毅，任重而道远。
5.学了本文，你受到哪些教益？

How Do I Like to Travel
Many people like to travel by plane, but I don’t like it because an airport is usually far from the city. You have to get there early and wait for hours for the plane to take off and it is often late. You can’t open the window. You can’t choose the food. Planes are fast, but they still take hours to get out of the airport and into the city.
I like travelling by train. I think trains are safe. Railway stations are usually in cities. When you are late for a train you can catch another one. You can walk around in the train and open the windows. You can see many interesting things on your way. I know it takes a little more time.
I also like cars. You can start your journey when you want to, and you don’t need to get to a railway station or a bus stop early. Also you can carry many things with you in a car. But sometimes there are too many cars on the road.
1. Why do many people like to travel by plane? ____.
A. Because it is fast
B. Because it is safe
C. Because you can walk around in the plane
2. Which is NOT the good thing about the train? ____.
A. It is safe
B. It takes a little more time
C. You can open the windows
3. If you want to take a lot of things with you, what do you take to go out? ____.
A. A busB. A carC. A train
4. What is the bad thing about the car? ____.
A. You needn’t go to a station
B. You can start your journey when you want to
C. There are too many cars on the road
5. What does the writer think of the plane, train and car? ____.
A. He thinks it takes a lot of time to go to and get out of the airport
B. He likes to take a train because it takes a little more time
C. He likes to take a car because he has a car
