But to be a great teacher, it's just as important to be a good person. In some countries, teachers are even more highly thought of than doctors and lawyers.Carmen Maura is an English teacher at a high school in Madrid, Spain. She is not only loved by her students, but the parents love her, too. They say that learning to speak English has not only been easy with her, but also a lot of fun. Carmen tells stories about the United States, England, and the other places where she has traveled. She teaches grammar with music and sometimes uses her love of cooking to help explain new words. On weekends, she even invites her students over for dinner where they can speak English in a relaxed atmosphere.So what can a teacher learn from Carmen Maura? First, she knows that teaching English is important, but teaching about herself and her own life isalso important. In her free time, she learns new things so that she always has something interesting to talk about in the classroom. Second, she loves her students. She tries hard to be fair to each one of them, and she knows them all by name. Finally, and perhaps most importantly, she believes in the future. She believes in creating future citizens who are open-minded, kind, and respectful of other people's cultures and ideas. Carmen Maura is a great teacher. She also knows that she is in a position to influence the future. So, she teaches reading, writing, speaking, and math. But she also teaches life.21.

九年级物理知识点填空题

九年级物理知识点填空题一、填空题。

1. 一切物体在没有受到力的作用时，总保持______状态或______状态，这就是牛顿第一定律。

- 答案：静止；匀速直线运动。

- 解析：牛顿第一定律描述了物体在不受力时的两种可能状态，静止是物体的速度为0的状态，匀速直线运动是物体保持速度大小和方向不变的运动状态。

2. 作用在同一物体上的两个力，如果大小______，方向______，并且在同一条直线上，这两个力就彼此平衡。

- 答案：相等；相反。

- 解析：二力平衡的条件是大小相等、方向相反、作用在同一条直线上、作用在同一个物体上。

这是解决很多力学平衡问题的基础。

3. 压强的计算公式是______，其中压力的单位是______，受力面积的单位是______，压强的单位是______。

- 答案：p = (F)/(S)；牛（N）；平方米（m^2）；帕斯卡（Pa）。

- 解析：压强表示压力的作用效果，p=(F)/(S)，根据公式中各物理量的定义，压力的单位是牛顿，受力面积是面积单位平方米，压强是由压力和受力面积相除得到的复合单位帕斯卡。

4. 液体压强的特点：液体内部向______都有压强；在同一深度，液体向各个方向的压强______；液体的压强随深度的增加而______；不同液体的压强还跟它的______有关。

- 答案：各个方向；相等；增大；密度。

- 解析：液体压强的这些特点是通过实验探究得出的。

液体由于具有流动性，所以内部向各个方向都有压强；在同一深度，压强相等；深度增加，压强增大；不同液体密度不同，压强也不同。

5. 阿基米德原理的内容是：浸在液体中的物体受到向上的浮力，浮力的大小等于______。

公式表示为______。

- 答案：物体排开液体所受的重力；F_浮=G_排=ρ_液gV_排。

- 解析：阿基米德原理是浮力计算的重要依据，它表明浮力的大小取决于液体的密度ρ_液、物体排开液体的体积V_排，g是重力加速度。

6. 当物体漂浮在液面上时，浮力______重力；当物体悬浮在液体中时，浮力______重力；当物体下沉时，浮力______重力。

江阴市夏港中学初中英语九年级全册Unit 9知识点(含答案)

一、选择题1．Amazing China is _____ that large numbers of people can’t wait to see the film.A．such a great documentary B．a very great documentaryC．quite a great documentary D．too great a documentary A解析：A【详解】句意：《厉害了，我的国》是这么好的的一部纪录片，以至于很多人迫不及待地想看这部电影。

考查such…that…引导的结果状语从句such…that…引导的结果状语从句的构成：（1）such a/an +形容词+可数名词单数+that+从句；（2）such +形容词+可数名词复数或不可数名词+that+从句。

结合句意可知填such a great documentary；选A。

2．Anyone _____________ with what I said may put up your hands.A．who agree B．which agree C．who agrees D．which agrees C解析：C【详解】句意：任何同意我所说的人都可以举手。

考查定语从句，观察句子anyone为先行词，意为任何一个人，为单数，所以用agrees；又因为它是指人，所以应该用由who引导的定语从句，故选：C。

【点睛】在复合句中，修饰某一名词或代词的从句叫定语从句。

被修饰的名词或代词叫先行词，定语从句一般放在先行词的后面。

1.that 既可以用于指人，也可以用于指物。

在从句中作主语或宾语，作主语时不可省略，作宾语可省略。

.which用于指物，在句中作主语或宾语，作主语不可省略，作宾语可省略。

3.who,whom用于指人，who 用作主语，whom用作宾语。

在口语中，有时可用who代替whom，也可省略。

注意：（1）当定语从句中含有介词，介词放在句末时，who，that，which可省略，但介词在关系代词前时，只能用“介词+which/whom”结构。

第九单元《溶液》知识点
一、溶液的形成
1、溶液
（1）概念：__________________________________________________，叫做溶液
（2）基本特征：_______、________
注意：a、溶液不一定无色，如硫酸铜为蓝色、硫酸亚铁为浅绿色、硫酸铁为黄色
b、溶质可以是固体、液体或气体；水是最常用的溶剂，如无说明，默认水为溶剂。

c、溶液的质量 = 溶质的质量 + 溶剂的质量
溶液的体积≠溶质的体积 + 溶剂的体积（分子间有间隙）
d、溶液的名称：溶质的溶剂溶液（如：碘酒——碘的酒精溶液）
e、固体、气体溶于液体，液体为溶剂
2、溶质和溶剂的判断
（1）有水，________
（2）液体溶于液体，无水，____________
3、饱和溶液、不饱和溶液
（1）概念：在__________，向____________加入某种溶质，当溶质______________，所得到的溶液叫做这种溶质的饱和溶液；还______________，叫做这种溶质的不饱和
溶液。

（2）判断方法：看有无不溶物或继续加入该溶质，看能否溶解
（3）饱和溶液和不饱和溶液之间的转化
饱和溶液不饱和溶液：_________、___________
不饱和溶液饱和溶液：增加溶质、蒸发溶剂、降低温度
注：①Ca(OH)2和气体等除外，Ca(OH)2的溶解度随温度升高而降低
②最可靠的方法是：加溶质、蒸发溶剂
（4）浓、稀溶液与饱和不饱和溶液之间的关系
①饱和溶液不一定是浓溶液（可能溶解度很小，如饱和的石灰水溶液就是稀溶液）
②不饱和溶液不一定是稀溶液（溶解度很大，即使未达到饱和也已经溶解了大量溶质）
③在一定温度时，同一种溶质的饱和溶液一定要比它的不饱和溶液浓
（5）溶解时放热、吸热现象（根本原因是水解作用和水合作用的热量变化不同）
溶解吸热：如硝酸铵NH4NO3溶解
溶解放热：如氢氧化钠NaOH溶解、浓H2SO4溶解
溶解没有明显热现象：如NaCl
二、溶解度
1、固体的溶解度
（1）定义：__________________________________________
四要素：①条件：一定温度②标准：100g溶剂
③状态：达到饱和④质量：单位：克
（2）含义：
20℃时NaCl的溶液度为36g含义：
在20℃时，在100克水中最多能溶解_______NaCl或在20℃时，NaCl在100克水中达到饱和状态时所溶解的质量为______
（3）影响固体溶解度的因素：①内因：溶质、溶剂的性质（种类）②外因：______ 大多数固体物的溶解度随温度升高而升高；如KNO3
溶解度/g t/℃ 21m m m m 少数固体物质的溶解度受温度的影响很小；如NaCl
极少数物质溶解度随温度升高而降低。

如Ca(OH)2
（4）溶解度曲线
①点：
I 、曲线上的点：表示_______________。

如:下图中a 表示A 物质在t 1℃时溶解度为m 1g 。

曲线上方的点：表示在对应温度下该物质的饱和溶液中存在不能继续溶解的溶质。

如:图中b 表示在t 1℃时，A 的饱和溶液中有(m 2-m 1)g 未溶解的溶质。

曲线下方的点：表示在对应温度下该物质的__________。

如：图中C 表示在t 1℃时，A 的不饱和溶液中，还需要加入(m 1-m 3)gA 物质才达到饱和。

II 、曲线交点：表示在对应温度下_______________。

如图中d 表示在t 2℃，A 、B 两物质的溶解度都为m 4g 。

②线：
如图中A 物质的溶解度随温度升高而明显增大，A 曲线为“陡升型”。

如KNO 3等大多数固体物质：图中B 物质的溶解度随温度变化不大，B 曲线为“缓升型”，如NaCl 等少数固体物质。

图中C 物质的溶解度随温度升高而减小，C 曲线为“下降型”，如气体及Ca(OH)2等极少数固体物质。

③掌握溶解度曲线的应用
I 、溶解度曲线上的每一点，代表着某温度下某物质的溶解度，因此利用溶解度曲线可以查出某物质在不同温度下的溶解度，并根据物质的溶解度判断其溶解性。

II 、可以比较在同一温度下不同物质溶解度的相对大小。

III 、根据溶解度曲线的形状走向，可以看出某物质的溶解度随温度的变化情况。

并根据此情况可以确定从饱和溶液中析出晶体或进行混合物分离提纯的方法。

例如：某物质的溶解度曲线“陡”，表明该物质溶解度随温度变化明显，提纯或分离该物质时适合采用降温结晶法。

某物质溶解度曲线“平缓”，提纯或分离该物质时适合采用蒸发溶剂法。

IV 、从溶解度曲线上的交点，可以判断哪些物质在该点所示的温度下具有相同的溶解度。

V 、利用溶解度曲线可以确定一定质量的某物质的饱和溶液降温时析出晶体的质量。

溶解度/g
2、气体的溶解度
（1）气体溶解度的定义：在压____________________，气体溶解在________达到饱和状态时的气体体积。

（2）影响因素： ①气体的性质
②温度（温度越高，气体溶解度越小）
③压强（压强越大，气体溶解度越大）
3、混合物的分离
（1）过滤法：分离可溶物 + 难溶物
（2）结晶法：分离几种可溶性物质
结晶的两种方法：①蒸发溶剂，如NaCl （海水晒盐）
②降低温度（冷却热的饱和溶液，如KNO3）
三、溶质的质量分数
1、公式：
溶质质量分数=溶液质量溶质质量× 100% =溶质质量
溶剂质量溶质质量+×100% 2、在饱和溶液中：
溶质质量分数C%=S
S +溶剂质量× 100% （注：数值上C < S 如溶解度为30克的固体，饱和溶液的溶质质量分数一定小于30%）
3、配制一定溶质质量分数的溶液(考点)
实验仪器：________________、托盘天平、药匙、胶头滴管
实验步骤：计算、称量(固体溶质)或量取(液体物质)、溶解、装瓶，贴签。

以配制50g 溶质质量分数为5%的蔗糖溶液为例说明。

（1）_____
根据溶质质量分数的公式，计算配制50g 溶质质量分数为5%的蔗糖溶液所需要的：①蔗糖质量：50g ×5%＝2.5g ，②水的质量：50g －2.5g ＝47.5g 。

（2）______
用托盘天平称2.5g 蔗糖倒入烧杯中，近似认为水的密度为1g/cm 3，用量筒量取47.5mL 水。

（3）______
把量好的水倒入盛有蔗糖的烧杯中，用玻琉棒搅拌，加速蔗糖的溶解。

（4）___________
把配好的溶液装入试剂瓶中，盖好瓶塞并贴上标签，标签上注明溶液的名称以及溶质的质量分数，放到试剂柜中。
