中考英语总复习----代词 导学案

初中英语代词的用法 一.人称代词 2. 人称代词的基本用法: 主格:用作句子的主语,放在动词前(疑问句式放在特殊动词后); e.g She lives in Toronto, Canada. 宾格:用作句子的宾语,放在动词或介词后; e.g Yesterday my mother bought me a new bike. I usually go to movies with her on weekends. 形容词性物主代词:用作句子的定语,之后必须带名词; e.g This is my book. That’s his book. 名词性物主代词:相当于一个名词词组,之后不能带名词(其代换的名词需在前文中出现); e.g His book is much newer than mine(= my book). 反身代词:一般放在动词后,要求同主语人称一致。 e.g She teaches herself English. 3. 名词性物主代词作主语时,主谓一致关系:名词性物主代词作主语时,其后的谓语动词形式应同它所代换的名词形式保持一致。 e.g My shoes are cheap. But his _____ expensive. A. is B. are C. be D. am 4. 反身代词的正确写法(单复数的判断)以及所属关系的表示: (1)使用反身代词时,应注意根据句中的某些词语推断其单复数形式,并注意其正确写法。 e.g Please help _____ to some cakes, children. A. you B. yourself C. yourselves D. your (2)在说明“某人自己的”时,不能用反身代词加所有格符号表示,而应用“形容词性物主代词+own+名词”表示。 e.g 错:He drove himself’s car to go camping last Sunday. 对:He drove his own car to go camping last Sunday. 5. 双重所有格的使用:在“数词+名词+of+人称代词”这样的词组中,人称代词应使用名词性物主代词,同of一起构成双重所有格形式。 e.g 错:Lucy is a good friend of me. 对:Lucy is a good friend of mine. 6. 几个人称代词连用时的位置关系:几个人称代词同时作某一成分时,应将第二人称放在最前面,而将第一人称放最后。 e.g You , he and I are good friends. These books are for you and me.

【 精品导学案】高中化学 2.3.2化学反应的限度学案 新人教版必修二

第2课时化学反应的限度 1.了解化学反应的可逆性,知道化学反应是有一定限度的。 2.了解化学平衡状态的判定方法。 3.了解控制反应条件对生产、生活及科学研究的意义。 本课时宜从日常生活和实验中的化学现象引出有关的概念和原理,经过对化学反应的可逆性→可逆反应→化学平衡状态的分析推进,让学生认识化学反应是有限度的。 1.可逆反应 (1)在同一条件下,①正向反应(反应物→生成物)和②逆向反应(生成物→反应物)能同时进行的化学反应称为可逆反应。 (2)可逆反应的特点有“四同”:同一反应;(反应处于)同一条件;(正、逆反应)同时进行;(反应物和生成物)同时存在。 (3)可逆反应用化学方程式表示时,不用“”,而用“③”。 2.化学反应的限度 (1)化学平衡状态的建立 在密闭容器中加入1 mol H2和1 mol I2发生反应: H2(g)+I2(g)2HI(g) 对于以上反应: ①当反应刚开始时,反应物的浓度④最大。 ②当反应刚开始时,正反应速率⑤最大。 ③随着反应的进行,反应物浓度逐渐减小,生成物浓度逐渐增大。 ④随着反应的进行,v(正)逐渐减小,v(逆)逐渐增大,达到平衡时,v(正)=v(逆)。 ⑤反应进行到⑥v(正)=v(逆)时,宏观上处于“静止”状态。 ⑥此时,反应物和生成物浓度不再改变。 ⑦这个状态称为⑦化学平衡状态。 ⑧此时反应未停止,仍在进行,只是任何一种物质反应掉的速率和生成的速率相等。 (2)化学平衡状态的特点 化学平衡状态是可逆反应达到的一种特殊状态,是在给定条件下所能达到的最大限度,当可逆反应达到平衡状态时,v(正)=v(逆)≠0。 3.化学反应条件的控制 (1)在生产、生活中,化学反应条件的控制主要是促进有利反应和控制有害反应两个方面: ①促进有利反应,提高原料利用率,加快有利反应的速率; ②控制有害反应,减少甚至消除有害物质的产生,减慢有害反应的速率。 (2)为加快煤燃烧的反应速率,对煤炭颗粒的要求是⑧越小越好,对空气的要求是保持适当过量,并保证煤炭与空气中的氧气⑨充分接触。

中考英语语法精讲 主谓一致教案

2017中考英语语法精讲:主谓一致 【教学目标】 熟练掌握语法一致原则,意义一致原则,就近原则。 【教学内容】 语法一致原则 主语和谓语通常是在语法形式上取得一致,即主语是单数形式时,谓语动词也采用单数形式; 主语是复数形式时,谓语动词也采用复数形式。 1.当and或both... and...连接表示不同概念的名词作主语时,谓语动词用复数形式。如:Tom and Mike are good friends.汤姆和迈克是好朋友。 Both Lucy and Lily are students.露西和莉莉都是学生。 2.不定代词either,neither,each one,the other,another,anybody, anyone, anything, someone, somebody, som ething, everyone,everybody,everything,nobody,no one,nothing 等作主语时,谓语动词用单数形式。如: Is there anything wrong with your bike? 你的自行车有什么毛病吗? Everyone is ready for the sports meeting. 大家都为运动会做好了准备。 3.由each...and each...,ever...and every...作主语时,谓语动词用单数形式。如: Each boy and( each) girl was given a new book. 给了每一个男孩和每一个女孩一本新书。 4.主语后接由with,along with,together with,as well as,rather than,including,besides,like,except' but等词或短语连接的名词时,谓语动词的单复数形式由主语的单复数形式决定。如: Mr. Green with his wife and two daughters is coming to Beijing. 格林先生将和他的夫人及两个女儿一块儿来北京。 5.“a number of+名词复数”作主语时,谓语动词用复数形式;“the number of+名词复数”作主语时,谓语动词用单数形式。如: A number of trees are cut down.许多树木被砍倒了。 The number of students in our class is 32.

高中化学必修二(新教材) 全书导学案

第1章原子结构 元素周期律 第1节原子结构与元素性质 第1课时原子结构 核心素养发展重点学业要求 通过宏观辨识与微观探析,深化对原子 结构的认识。 1.认识原子核的结构,明确质量数和A Z X 的含义。 2.掌握构成原子的微粒间的关系。 3.知道元素、核素、同位素的含义。 学生自主学习 原子核 1.原子的构成 原子 ? ? ?原子核 ? ? ? ? ? ? 质子(带1个单位正电荷) 中子(不带电) 决定原子质量 核外电子(带1个单位负电荷),质量很小 2.原子中各微粒间的数量关系 (1)原子序数=□01核电荷数=质子数=核外电子数。 (2)质量数(A)=□02质子数(Z)+□03中子数(N)。 3.原子构成的表示方法 如16 8O表示质量数为□0416,质子数为□058的氧原子。 核素同位素 1.核素 具有相同数目的□01质子和相同数目的□02中子的一类原子。

氢元素有氕、氘、氚三种核素,分别用□0311H、21H、3 1 H表示。 2.同位素 □04质子数相同而□05中子数不同的同一种元素的不同核素互为同位素。例如 1 1 H与□0621H、31H互为同位素。同位素分为□07稳定同位素和□08放射性同位素。 课堂互动探究 一、原子的构成 1.离子的质量数是否等于其质子数和中子数之和? 提示:是。因为离子是通过得失核外电子形成的,而质量数只与核内质子数和中子数有关,与核外电子数无关。 2.任何原子都是由质子、中子和电子构成的吗? 提示:不一定。11H中含有一个质子和一个电子,不含有中子。 1.原子的相对质量(M)=原子质量 m(126C) 12 ≈质量数=质子数+中子数。 2.原子、离子组成中的数量关系 (1)核电荷数=质子数=原子核外电子数。 (2)质量数(A)=质子数(Z)+中子数(N)。 (3)阳离子中:质子数=核电荷数=核外电子数+离子电荷数。 (4)阴离子中:质子数=核电荷数=核外电子数-离子电荷数。 知识拓展 核力是使核子组成原子核的作用力,属于强相互作用力的一类。原子核中有中子、质子,质子是带正电的,所以质子之间会互相排斥。是非常强大的核力将它们吸引在一起,使它们在非常小的区域形成原子核。核力是短程力,只有在原子核尺度上才显现出来。 1.已知R2+核外有a个电子,核内有b个中子,表示R原子符号正确的是() A.b a R B.a+b-2 a+2 R
