八年级上学期历史期中考试知识点 第1课鸦片战争 中国近代史起止时间是1840年到1949年，中国近代史的社会性质：半殖民地半封建社会。鸦片战争是中国近代史的开端。 鸦片战争（即第一次鸦片战争）（1840.6—1842.8） 一、林则徐虎门销烟 A 英国走私鸦片的原因：扭转对华贸易逆差, 根本目的：打开中国市场。 B鸦片输入中国的危害（即禁烟的原因）： 白银大量外流，威胁到清政府的财政，也加重了人民的负担。人们的身心健康受到严重摧残，官吏更加腐败，军队的战斗力削弱。因此，鸦片的输入，给中华民族带来沉重的灾难。 C 林则徐禁烟的目的是：维护清政府的统治。 经过：1839年6月3日到25日，林则徐下令将缴获的全部鸦片在虎门海滩当众销毁。 意义：虎门销烟是中国禁烟运动的重大胜利。打击了外国侵略者的气焰，表明了中国人民维护民族尊严的决心。 （纪念虎门销烟，联合国确定6月3日为“国际禁烟日”，6月26日为“国际禁毒日”。） 二、《南京条约》——中国近代史上第一个不平等条约 1、背景（原因）：鸦片战争，中国军队失败： （1）英国发动鸦片战争的根本原因：为了打开中国市场、推销工业品，掠夺廉价的工业原料。 英国发动鸦片战争的借口（直接原因、导火线）：林则徐虎门销烟。 （2）鸦片战争爆发标志：1840年6月，英国舰队开到广东海面，进行挑衅，鸦片战争爆发。（3）1841年初，英军占领香港岛。1842年，中国近代第一个不平等的条约──中英《南京条约》签订 2、中英《南京条约》内容：割香港岛给英国；赔款2100万元；开放广州、厦门、福建、宁波、上海五处为通商口岸；英商进出口货物缴纳的税款，中国须同英国商定。（使中国丧失领土和关税两大主权） 三、鸦片战争影响（危害）：鸦片战争以后，中国开始从封建社会逐步沦为半殖民地半封建社会。鸦片战争是中国近代史的开端。 【鸦片战争的影响（详解）】：①中国开始从封建社会进入半殖民地半封建社会（社会性质）； ②中国主权遭到破坏，开始丧失独立自主地位（政治方面）； ③成为外国倾销工业品的市场和掠夺原材料产地，自然经济开始解体（经济上）； ④外国资本主义和中华民族的矛盾成为最主要矛盾（社会矛盾）； ⑤中国开始进入反侵略，反封建的旧民主主义革命时期（社会任务）。 鸦片战争是中国历史的转折点，是中国近代史的开端。（因为鸦片战争它改变了中国的社会性质） 《南京条约》中最能体现英国的意图，并对中国民族经济危害最大的是：商定税款。 【活动与探究】鸦片战争中中国战败的原因： ①清朝政治腐败，经济和军事技术落后。②道光帝举棋不定，忽战忽和。③英国国力强盛，武器先进。（其中“清朝政治腐败”是主要原因，也可以说为：腐朽的封建制度阻挡不了新兴的资本主义的进攻）（说明了：落后必然挨打。要毋忘国耻，立志进取） 第2课第二次鸦片战争期间列强侵华罪行
8.2《电功率》 教学目标： 1. 知道电功率的定义、定义式、单位。 2. 理解额定电压、额定功率，会区分额定功率与实际功率。 3. 知道实验室测电功率的原理；会用电功率公式进行简单计算。 学习重点：电功率的相关计算 学习难点：对额定功率、额定电压等概念的理解 学习过程： 动手实验：将15W ffi 100W的灯泡分别与电能表连在一起单独工作，认真观察电能表铝盘转动的快慢。看看两者消耗电能的快慢是否一样？ 知识点一：电功率的基础知识 1、电功率 ⑴电功率是用来表示快慢的物理量。 ⑵电功率的定义〒。这种定义方法叫 ⑶电功率的计算公式为P= ;变形公式：W= ⑷国际单位是，常用单位。 2、自学课本上的例题。 例：40W的灯泡正常工作2h，求消耗的电能? 在更讲解电能两个单位的计薛方袪* 电功率、时间的单位分别取些5时.邑能的单位是几 电功率、时间的单位分别取科、h时.电能的单位是収叭k 强调对两蓉单位的統一n 知识点二：额定功率 3、额定电压与额定功率 （1）“额定电压”的定义_______________________________________ 。
“额定功率”的定义________________________________________ 。 （2）_______________________________________________________ 灯泡上标着 “ PZ220-「--25” ,其物理意义是 ______________________________ ____________ 思考：若加在用电器两端的实际电压不等于额定电压，则用电器消耗的实际功率 还是额定功率吗？对灯泡来说其实际功率越大，灯泡越亮！ （3）实验室通常通过电流表测___________ 和用电压表测 __________ ，根据公式P=来测定用电器的功率。结合开始的实验思考：利用电能表和秒表怎样测用电器的功率？巩固练习： 1. 某用电器电功率是800W 其物理意义是______________________________ 。 2. 判定下列说法是否正确： （1）电流通过用电器时做功越多，电功率越大。（） （2）电流通过用电器时电功率越大，做功越多。（） （3）电流通过用电器时电功率越大，做功越快。（） 3. 一用电器在10min内做功440J,则此用电器的功率是___________ W 4. 某电路两端的电压是30V,4S内电流做功240J,则这段电路的电功率是___________ W, 通过的电流是______ A,这段电路的电阻是_______ Q 。 5. 一台式计算机正常工作时，电功率最接近于（） A 2W B、20W C 、200W D、2000W 6. 把标有“PZ220-100”、“PZ220-60”字样的两盏电灯，串联后接在220V的电路 里，两盏灯比它们正常发光时都暗，这是因为两盏灯的（） A.额定电压变小了 B. 额定功率变小了 C.实际电压大于额定电压 D. 实际功率小于额定功率

作者：郭尚民 在迷人的神话中，最神奇的土壤是五色土在神秘的园林中，最鲜艳的花朵是五色花在难忘的校园中，最美丽的校园是实验 （一） 实验是红色的，红得雄浑庄重 实验是金色的，格外典雅尊贵 朱漆的大门饱经五十多年风雨的洗礼，关起来品味历史，敞开来接纳现代 登攀碑的金色圆顶吸引多少人的目光，一半是仰慕赞叹，一半是向往希冀 红色是实验胸前的绶带， 鼓励他敢为披荆斩棘的勇士 金色是实验头顶上的王冠 赞美它永做培桃育李的有冕之王 红色是成长的颜色， 随着记忆一起涌动的，还有青春的血液金色是梦想的颜色， 伴着梦想一起飞翔的还有金色的韶华
实验是绿色的，绿的青葱郁勃 实验是蓝色的，蓝的宁静深沉 爬山虎的足迹是绿色的， 一年又一年，总是站到最高处 少年的校服是蓝色的， 一天又一天，离开校园也用心珍藏实验的绿茵场是翡翠绿的， 每一棵小草都张扬着主动发展的生机实验的天空是蓝色的， 向人们昭示着无限空间的魅力 绿色是希望的颜色， 有绿色就能编制美丽的神话 蓝色是憧憬的颜色， 有蓝色就有希望看到指路的灯塔 （三） 实验还有一种颜色， 那就是起跑线的白色 实验还有一种心情 那就是对新学期的盼望 今天，我们又一次站在白色起跑线上
仍然固守着登攀不止，敢为人先的执着今天，我们又一次迎来新学期的曙光仍然追寻着博学日新，德行天下的目标白色的起跑线刻画在实验的每一个角落知识是智慧的起跑线 快乐是健康的起跑线 品德是人生的起跑线 实验是理想的起跑线 五彩缤纷的实验啊，五彩缤纷的生活五彩缤纷的实验啊，五彩缤纷的理想我们用你装点了自己最美丽的青春岁月我们将用一生的色彩装扮你的容颜 是的，我们将从这里走向成功 好吧，让我们从今天走向辉煌
