Based on the bestselling novel written by Ken Follett, this TV show starring the brilliant Eddie Redmayne is widely recognized as one of the best historical TV dramas of recent years.MahabharataThis Indian Hindilanguage series is liked by many people for being regarded as the simplest and the most fun way to learn about the ageold wisdom of the Indian people.It tells us about the kings and heroes who love, fight and make wise decisions.This drama is about the endless struggle between good and evil.The CrownThis story about the transformation of the young Princess Elizabeth into the queen shows everything about the British monarchy (君主制)．It includes many storylines, each of which could be made into a separate TV show.The series focuses on the age old themes of family, marriage and politics, and this is probably what makes The Crown win popularity.语篇解读：本文是一篇应用文。

(人教版)初中九年级化学中考一轮复习《走进化学实验室》教学案设计表
年级九年级学科化学制定日期课型复习课课题走进化学实验室主备人执教人使用时间教学目标知识与技能目标1．能记住并说出一些常用的仪器的名称、用途和使用方法。
2．能说出一些药品的名称。
3．能记住并遵守实验室化学药品的取用规则，养成良好的实验习惯。
4．能正确取用固体药品和液体药品，取用动作规范。
过程与方法目标通过本节课的复习，提高学生对常见仪器的使用的能力。
情感态度与价值观培养学生严谨的科学态度。
初步使学生养成良好的实验习惯教学重点1．常用的仪器的名称、用途和使用方法；2.固体和液体药品的取用。
教学难点1．常用的仪器的名称、用途和使用方法；2.固体和液体药品的取用。
一、考点梳理复习方式：自主复习记忆（回归课本）考点1、常用仪器、药品的取用1.药品取用规则：①“三不”原则；②节约原则；③处理原则。
2.固体药品的取用：其操作要领是一横二放三慢竖。
3.液体药品的取用：瓶塞倒放，标签向手心，瓶口要紧挨试管口。
4.量筒的使用：量筒放平，读数时视线要与量筒内液体的凹液面的最低处保持水平。
5.滴管的使用：取液后的滴管应保持橡胶胶帽在上，不能平放或倒置；使用时在试管(或烧杯)的正上方垂直滴加药液，不能伸到容器内。
1.取用液体药品时，瓶塞倒放是为了防止瓶塞被污染后再污染试剂瓶中的试剂；标签向手心，目的是为了防止残留的药液腐蚀标签；倾倒液体时，瓶口紧挨试管口且缓慢倾倒的目的是避免试剂流到试管外。
个人修订学生起立记忆课本知识点，教师进行巡视，对于坐下的同学进行抽查。
教师边梳理边提问本节课重要知识点.2.量筒仰视读数时，会比实际值小，俯视读数时，会比实际值大。
3.测量读数时，要注意仪器的精确度，以免造成实验数据错误。
4.固体存放在广口瓶中，细口瓶(液体)，滴瓶(少量的液体)，集气瓶(气体)。
用量筒量取一定体积液体时，一般要选择量程与所需要量取的液体体积最接近的且大于所要量取的液体体积的量筒，这样可以减小误差。
考点2、物质加热、仪器的连接与洗涤1.酒精灯的使用：①绝对禁止向燃着的酒精灯内添加酒精；②绝对禁止用燃着的酒精灯去引燃另一个酒精灯；③熄灭酒精灯必须用灯帽盖灭，不可用嘴去吹。

四．重点语法（一）when, while 和as 引导时间状语从句的用法1、when 的用法如果只从现象来看，when 从句用的最多的是一般过去时，而主句的时态没有限制,根据具体情况而定。
1). When he was a child he was always trying out new ideas.他小时候就常常试验一些新的设想。
2). When she came into my room, I was just reading a book. 她走进我房间时，我正在看书。
2、while 的用法相比于when 来说，while 从句的侧重点就不一样了。
while 从句的侧重点在于描述动作正在发生的状态，它的意思是：当while 事件正在发生的时候，另一件事如何如何。
所以，while 从句一般用的是正在进行时。
而另一件事的状态没有硬性的要求，根据具体情况而定。
例如：1). While my wife was reading the newspaper, I was watching TV.当妻子正在看报纸的时候，我正在看电视。
2). While Jim was mending his bike, Lin Tao came to see him.正当吉姆修自行车时，林涛来看他。
3、as 的用法as 从句表示的也是一件事情正在发生，另一件事也正在进行当中。
as 从句可用一般过去时，可以翻译成“边……边……”。
例如：1). As my mother sang those old songs, tears ran down her cheeks.当我妈妈唱起那些老歌时，眼泪顺着她的脸颊流了下来。
2). The students took notes as they listened. 学生们边听课边做笔记。
as 表达的事件，往往只是主句动作发生的背景或条件时，as 只是一个次要的时间说明，不像while 从句有强调while 动作本身的意思。
因此，as 常常翻译成“随着……”之意。
例如：1). As the time went on，the weather got worse. 随着时间的推移，气候更加糟糕。
2). The atmosphere gets thinner and thinner as the height increases.随着高度的增加，大气越来越稀薄。
少数情况下，如果强调动作正在发生，as 从句也可以用正在进行时。
