E、短文填空。

It’s importa nt to develop the healthy habits in your daily life. The following will help you become healthier and keep perfect shape.

Eat properly. A healthy diet is very important for everybody. Breakfast is the most important meal in a day. Doctors suggest that stud ents’ breakfast should include fruit, eggs, milk, rice or noodles, because these can offer them necessary energy, help them listen carefully in class and keep them healthy. Eat enough for lunch and little for supper. But remember that too much sugar is bad for your teeth and blood. You shouldn’t have too many sweet snacks and desserts in your diet, even though such food tastes delicious.

Keep off germs (病菌). Daily tooth cleaning reduces the amount of germs which will spread diseases. Germs in the mouth are likely to enter the blood and cause illness, even heart disease. Even if you’re not sick, always remember to cough or sneeze into your arms instead of your hands because hands can spread germs to others when you touch something else. Besides, washing hands is necessary after going to the toilet or before having a meal. And you'd better rub both hands while washing them.

Exercise regularly.Regular exercise can improve your moods and balance. What’s more, it’s good for bones. There are many forms of exercise: walking or running for about 30 minutes a day, playing ball games twice or three times a week, swimming or dancing often. You can choose your favorite to practice regularly. You will not only feel energetic but also think better after doing exercise.

Stay connected. Having regular communication with friends is the key to reducing stress. And sharing happiness and sadness, exchanging information with others can also help improve memory. Having a friend

学案-选修3-3 第八章 气体 知识点全面

第八章气体 第一节气体的等温变化 一、等温变化:一定质量的气体,在温度不变时发生的状态变化过程,叫做气体的等温变化。 实验:探究气体等温变化的规律 做一做:用注射器密闭一定质量的空气,缓慢地推动和拔出活塞,观察活塞中空气体积和压强的变化? 主要步骤:1、密封一定质量的气体。2、改变气体的体积,记录气体长度和该状态下压强的大小。3、数据处理。注意事项:1、尽量避免漏气。2、不要用手握住玻璃管。3、移动活塞要缓慢。 探究结论:在误差范围内,温度不变时,一定质量的气体压强p和体积V成反比。 误差分析:1、读数误差。2、漏气。 二、玻意耳定律 1、文字表述:一定质量某种气体,在温度不变的情况下,压强p与体积V成反比。 2、公式表述:pV=C(常数)或p1V1=p2V2 3、条件:气体质量一定且温度不变 4、适用范围:温度不太低,压强不太大 5、利用玻意耳定律的解题思路: (1)明确研究对象(气体); (2)分析过程特点,判断为等温过程; (3)列出初、末状态的p、V值; (4)根据p1V1=p2V2列式求解; 三、P-V图像(等温线) 物理意义:等温线上的某点表示气体的一个确定状态。同一条等温线上的各点温度相同,即p与V乘积相同。 不同温度下的等温线,离原点越远,温度越高。

第二节 气体的等容变化和等压变化 一、 气体的等容变化 1.等容变化:一定质量的某种气体,在体积不变时,压强随温度的变化叫做等容变化. 2.查理定律 ⑴内容:一定质量的某种气体,在体积不变的情况下,压强p 与热力学温度T 成正比。 ⑵表达式:① ② ⑶适用条件: 气体质量一定,体积不变 ⑷适用范围:压强不太大、温度不太低 3.等容线:一定质量的某种气体在体积不变时,压强随温度变化关系的图线,叫气体的等容线. 特点:等容线是延长线经过坐标原点的直线,图线上每一个点表示气体一个确定的状态,同一根等容线上各状态的 体积相同, 斜率反映体积大小 ,斜率越大,体积越小(同一温度下,压强大的体积小)如图所示,V 2

高中文言文知识点梳理学案

高中文言文知识点梳理学案 学案博苑 2012-01-08 0835 5d56b7b40102dtyf 高中文言文知识点梳理学案 教学目标 1、了解文言文词类活用现象,能够根据文言语境进行用法辨析。 2、能够根据文言语境辨析、推断词义,训练准确翻译文言语句的能力。 教学重难点 根据文言语境辨析、推断词义,训练并提高准确翻译文言语句的能力。 教学方法合作、探究 教学时数2课时 教学过程 第一课时 一.导入 文言文以简约的语言承载着传统文化的精华,经历了上千年锤炼的古典文学是我们民族精神内涵的源头活水。我们中学生要具有阅读浅易文言文的能力,文言文是“言”“文”并重的,这里的“言”,即文言知识,如实词理解,句式辨析等,今天我们就来梳理探究文言词语与句式。 一、文言词语 (一)词类活用 师词类活用是古汉语中某些实词的特殊用法,这些词在特定的语言环境中,临时具有某种语法功能,相应具有某一新的意义,并且临时改变了词性,有的还改变了读音。 (探究问题1、词类活用中意动与使动的区别是什么?) 学生展示合作探究成果 ①悦亲戚之情话(《归去来兮辞》) ②且庸人尚羞之(《廉颇蔺相如列传》) ③善万物之得时(《归去来 辞》) ④生乎吾前,其闻道也固先乎吾,吾从而师之(《师说》) ⑤越国以鄙远,君知其难也(《烛之武退秦师》) ⑥侣鱼虾而友麋鹿(《赤壁赋》) 以上例①到例③是形容词的意动用法,例④到例⑥是名词的意动用法。形容词的意动用法是主语认为宾语具有这个形容词所具有的属性,即认为宾语怎么样;名词的意动用法是主语认为宾语是这个名词所表示的事物,即认为宾语是什么或把宾语当作什么。

生乙①眄庭柯以怡颜(《归去来兮辞》) - ②铸以为金人十二,以弱天下之民(《过秦论》) ③士不敢弯弓而抱怨(《过秦论》) ④先破秦入咸阳者王之(《鸿门宴》 ⑤沛公旦日从百余骑见项王(《鸿门宴》 ⑥若亡郑而有益于君,敢以繁执事。(《烛之武退秦 师》) 以上例①到例③是形容词的使动用法,例④是名词的使动用法,例⑤到例⑥是动词的使动用法,古汉语的使动用法就是谓语表示主语使宾语怎么样的一种用法。 生丙意动用法与使动用法的主要区别是前者是主语认为宾语怎么样或是什么,(这种主观认识不一定与客观情况相符。)使动用法是表示(客观上即事实上)主语使宾语怎么样(或者使宾语将要发生某种变化)。丰衣足食使……丰 足。“丰、足”是客观上使“衣、食”发生了变化。 拓展练习 1、孔子登东山而小鲁,登泰山而小天下。(认为……小) 2、不远万里(认为……远) 3. 鱼肉百姓(以……为鱼肉。) 4、春风又绿江南岸(使……绿) 5、烛之武退秦师(使……退) (二)实词词义 师学习任何一种语言,语音、词汇、语法三者缺一不可,而三者之中,词汇居于首位。古代语言的词汇中最重要的是实词,文言实词的掌握应逐课积累,几年之后,水到渠成,这样就能达到阅读浅易文言文的要求。 (探究问题我们在阅读文言文遇到实词时,如何准确把握词语的意义?) 学生展示合作探究成果 生甲1、①引壶觞以自酌,眄庭柯以怡颜。(《归去来兮辞》) ②拔剑切而啖之(《鸿门宴》 其他例句略 根据以上例句,总结规律根据字形推断词义辨别 汉字本是具有表意性质的,从字形可以推知字义。汉字虽历经演变,表意的功能毕竟没有完全丧失,因此,通过对字形结构(主要是象形字、会意字和形声字)的分析可以帮助我们探求字的意义。(例①“眄”的含义,根据“目”和“眄”的对象“庭柯”就可知其大致是“看”的意思。例②“啖”的含义,根据“口”,就可知其大致是“吃”的意思。) 2、①据崤函之固,拥雍州之地。(《过秦论》) ②不积跬步,无以至千里;不积小流,无以成江海。 (《劝学》) 党同伐异 根据以上例句,总结规律利用结构相似的句式辨别 古人行文,往往采用一些字数同、结构相同或相似的语句,各句在相对应的位置上,使用同义、反义或意思相关的词,运用了排比、对偶等修辞,对这类句
