IV阅读并按要求完成各题 (共11小题, 每小题2分, 共22分)

( I )

“USA? Britain? Which country is better to study in?” We often hear such discussion. As China opens its door, studying abroad has become a dream for many Chinese students. They want to learn about the world. It’s true that studying abroad can help students develop themselves. Language skills will improve and it may be easier to fi nd a job.

But there are problems that should be considered. Language is the fi rst. Students must spend a lot of time learning another language and getting used to a different culture.

Students must also learn to live without parents’ care and deal with all kinds of things they haven’t had to do before, like looking after themselves. There are reports about Chinese students abroad sinking in an ocean of diffi culties and giving up easily. When they have to take care of themselves, it is hard for the students to study well.

Finally, studying abroad brings a heavy burden to the family. For most Chinese parents, the cost of studying abroad is very high. But is it worth it?

We know that there are many famous people who succeed in great things through their hard work in China. Liu Xiang is a good example. Once an American teacher invited him there but he refused. He kept training hard with his Chinese teacher. He surprised the world when he won a gold medal at Athens

Olympics. So when you wonder which country is better to study in, consider whether studying abroad is the right choice.

Jean is a bright young woman who comes from a rich and famous family. She goes to a good university and has everything that money can buy. Well, almost everything. (71) The problem is that the people in Jean’s family are so busy that they can hardly fi nd time to be with her. In fact, Jean is quite lonely.

So Jean spends a lot of time on her QQ. She likes being anonymous (匿名) , talking to people who do not know about her famous family and her rich life. She uses the name Linda on QQ and has made a lot of friends who she keeps in touch with quite often.

Last year Jean made a very special friend on QQ. His name was David and lived in San FranciscoDavid was full of stories and jokes. He and Jean had a common interest in rock music and modern dance. (72So it always took them hours to talk happily on QQ and sometimes they even forgot their time. Of coursethey wanted to know more about each other. David sent a picture of himself. He was a tall, good-lookingyoung man with a big, happy smile. As time went by, they became good friends and often sent cards andsmall things to each other.

When Jean’s father told her that he was going on a business trip to San Francisco, she asked him to let her go with him so that she could give David a surprise for his birthday. She would take him the latest DVD of their favorite rock singer. But when she knocked on David’s door in San Francisco, she found that her special friend was a twelve-year-old boy named Jim!

九年级化学上册竞赛 篇5

1、质量守恒定律内容?以及要注意那些重要的方面?

2、质量守恒定律的原因?

3、我们学习过那些化学变化?如何表示一个化学变化?书写碳、磷分别和氧气在点燃条件下反应以及水在通电条件下反应的文字表达式?

我是请了一个同学上黑板书写,在黑板上写的同学没有写完是我就让他停止了,而在座同学能够比她写的快的原因是我们用了化学式来书写表达式,同学们自然而然就知道文字表达式太麻烦不方便,并且不能国际通用。然后我就用化学式板书三表达式,大家对比一、二、三三个反应,立即能发现二三反应表达式不能体现我们化学变化遵循的质量守恒定律--原子个数改变了。所以我自然而然的就把化学方程的定义给出来了,但是书上定义很简单,我们化学方程式中除了化学式外,化学式前面还有一些数字(计量系数),是为了体现化学变化中的质量守恒定律的。

然后提问H、H2O的意义?那今天学的第三种化学用语化学方程式能表示那些意义呢?学生阅读教材,然后学生顺利总结出其三点意义,就学生讲的每一点意义通过我的三个化学方程式的例子学生一起朗读,请学生朗读的形式让学生理解。最后我用了两个化学方程式让学生练习意义,从不同角度讨论化学方程式提供的信息。我这节课的优点我觉得应该是我采用了层层递进提问的方式让学生理解化学方程式,对重难点的突破化学方程式意义的环节我没有采用讲授式而是让学生通过阅读教材后学生自己总结意义,然后通过集体练习和单独练习相结合的方式让学生真正理解化学方程式的意义。但是我这节课的不足之处也有以下几点:

1、我语速极快,使这节课节奏紧张显得不够从容;

2、在我书写的两个方程式中有两个最开始是未配平的,但是我带着学生把它们配平,大部分同学都不知道化学方程式中的计量系数是如何得来的,我当时应该补充一句化学方程式的配平我们下节课重点学习:

3、质量守恒定律的第二个意义各反应物和各生成物的质量比时我竟然没有把“:”表示出来。

4、最后在讨论S+O2=SO2提供给大家的信息是,我想鼓励同学们从不同角度来获得信息,这时我班的张闻讯同学十分的优秀在我追问了很多“还有吗”以后还能对答如流,其实这个时候我也表扬了他但是力度不够,不能引起其他同学的注意,并且在此我也没有给学生留下足够的时间思考,而是把她的话截断从而把学生引导到我的思路上,这应该是我的经验不足的原因没有处理好“预设和生成”。

九年级化学上册期末复习计划 篇6

一、班级现状分析:现在我任教的1、2、3班的化学期中考试基本情况如下:2班期中考试平均成绩倒数第一,但整体学习风气较好;3班基础较好但学习不扎实;1班学习兴趣不浓,学习习惯有待加强。

二、期末考试目标:

根据三个班的班情,期末考试总体目标是三个班的总平均分达到及格,各班平均分差距在6分之内。

三、整体复习计划:

章节复习,主要是知识点梳理填空、过关练习、章节练习、其中穿插部分考试,检测学生复习情况。其中最重要的一点,主要是让学生主动参与复习,老师少讲多点评。

四、具体复习方法:

1、梳理基础知识中,主要抓住基础薄弱的学生,让学生自己讲、自己填、自己记,确保每个学生都能掌握最基础的知识,都能拿到基础分。记不住的重新记、多次记、反复记,确保每个同学过关。

2、重点知识一定加大复习力度,让大多数学生都能非常熟悉解题思路和涉及到的相关课本知识,做到心中有数、考试稳重、不失误、少丢分。

3、适当培养学生分析解答信息题、实验探究题,提高学生利用所学知识分析解答问题的能力,而我们学生在迁移知识、运用知识方面存在较大问题。这方面的练习会在平时讲课中多加操练,让学生适应这种考察方式,掌握答题技巧,尽量争取考出更好成绩。

4、为了提高平均分,还应该准备一套针对差生的复习方法,计划在全班性复习的基础上,对差生“再炒一次回锅肉”,所以我准备在复习时让全班同学都做到全面复习的基础上,再给部分差生来一次“小炒”,争取让他们“回味无穷”。

对九年级化学若干问题的商榷 篇7

一、碳酸氢钠在医学上是否还用于治疗胃酸过多

教科书 (下册) 在十一单元“生活中常见的盐”课题中明确指出碳酸氢钠是治疗胃酸过多症的一种药剂。那么目前医疗中碳酸氢钠是否用于治疗胃酸过多呢?先通过网上查阅相关资料, 在得到否定答案后, 又咨询了人民医院有关消化内科专家, 他们一致认为过去医疗水平不发达的时候, 碳酸氢钠的确曾做过治疗胃酸过多的药物, 但现在临床上只是用它来治疗酸中毒, 已没有谁再用碳酸氢钠治疗胃酸过多症了。他们还认为碳酸氢钠不能用于治疗胃酸过多的原因主要是: (1) 它虽能够中和胃酸, 但不能抑制胃酸的分泌, 治标不治本; (2) 它对胃粘膜不仅无保护作用, 而且还会产生破坏

作用; (3) 产生的二氧化碳会反作用于胃壁, 刺激胃壁进一步分泌胃酸, 出现继发性胃酸增多。从我们化学角度来看, NaHCO3不适合做治疗胃酸过多的理由如下: (1) NaHCO3和HCl反应会生成二氧化碳气体, 使胃内气压升高; (2) NaHCO3和HCl反应较快, 所以药效不会持久。

我认为, 现行教科书中出现碳酸氢钠治疗胃酸过多症, 已不适应时代发展, 应删去, 以免误导学生。

二、二氧化碳能否用排水法收集

CO2能否用排水法收集?教科书 (上册) 第六单元“二氧化碳制取”课题中指出:“如果某气体要用排水法收集, 该气体必须是不易溶于水、不与水发生反应。”该课题的注释 (1) 也指出:当气体的密度和空气的密度相近且难溶于水时, 一般采用排水法。二氧化碳能溶于水, 而且能和水发生反应。那么二氧化碳能否采用排水法收集呢?虽然, 在本课题中没有明确的文字指出CO2不可以用排水法收集, 但从该课题中O2和CO2的制取装置及相关性质的比较、课本图6-10、“学完本课题你应该知道”栏目中实验室制取CO2的装置图等, 足以说明教科书是不赞同CO2用排水法收集的。

可令人不解的是, 在教科书上册“对人体吸入的空气和呼出的气体的探究”课题中就是用排水法收集呼出的气体, 并且用收集到的气体与空气中CO2含量作比较。难道这里用排水法收集呼出的气体就不需要考虑二氧化碳能溶于水且能与水反应这个性质了吗?显然课本内容前后矛盾!

那么二氧化碳到底能不能用排水法收集呢?我通过查阅相关文献知道, CO2稍溶于水, 在101kPa、293K时, 0.88体积的二氧化碳可溶解于1体积的水中。教科书在第六单元课题2和课题3中都讲到H2CO3很不稳定, 很容易分解生成CO2和H2O。事实上, 实验室制CO2的反应原理不也是先通过CaCO3和HCl反应生成H2CO3, 然后利用H2CO3不稳定, 而得到CO2和H2O的吗?由此可推测, 用排水法收集CO2, 只有很少部分的二氧化碳会与水反应生成H2CO3, 另外, H2CO3又很容易分解生成二氧化碳。众所周知, 实验室可利用启普发生器作为二氧化碳的发生装置, 不也正好承认二氧化碳是可以用排水法收集的吗?

我利用适量的块状石灰石和适量的稀盐酸 (比例约为1∶2) 制取CO2, 并用排水法收集250mL的CO2, 收集所用时间不到10s。而后, 我用澄清石灰水检验集气瓶中的气体, 发现澄清石灰水变浑浊, 充分震荡后浑浊又消失。这说明排水法收集到的气体是二氧化碳。我认为用排水法收集到的气体应该比用向上排空气法收集到的气体更纯净。

也许是受教科书的影响, 长期以来我们的教学参考用书、教辅用书、各种考试中都无一例外地认为二氧化碳是不可以用排水法收集的。所以, 我觉得我们的教科书应以事实为基础作出明确的叙述。

三、水蒸气能否抵消温室效应

教科书上册第117页有这样一句话:“有人认为大气中的水蒸气有可能抵消温室效应。”我认为这种说法是不对的。水蒸气能吸收太阳和地球表面热辐射到空间的红外辐射, 阻止能量向空间散失, 所以水蒸气可以导致温室效应是科学界不争的事实。简单地翻一下有关环境化学类的教科书或者在百度中搜索一下, 都很容易发现水蒸气是形成温室效应的主要物质之一。如果没有水蒸气的话, 地球将是一片苦寒死寂。正是凭借水蒸气的保温作用, 地球上的生物才能生活繁衍。二氧化碳只是让地球变热, 而水蒸气则会让地球变闷热, 那种滋味是更难受的。我想, 每年6月底7月初闷热的黄梅天气就能很好地说明这个问题。从这个角度来说, 水蒸气的危害甚至比二氧化碳严重。

教科书提到的“抵消温室效应”也许指的是由于烟尘增多而形成的“阳伞效应”。所以, 我觉得教科书应该更正这部分内容。

九年级化学中化学实验的作用初探 篇8

关键词:化学实验;学习兴趣;培养能力

化学实验室最生动、最直观的教学手段。九年级化学是学生学习化学的启蒙,首先要让学生对化学学习产生兴趣才能使学生进入稳定的学习,才能培养学生的观察能力、探究能力、创新意识的学习习惯。要达到目的就要充分发挥化学实验的功效。

九年级化学学习是学习化学的启蒙,而实验教学又给学生的启蒙学习提供直接的感性认识。学生虽然具有一定的生活经历,但与化学相联系的技能还欠缺,所以,教师在教学中一定注意演示实验教学的准确性和启发性才能激发学生的兴趣和求知欲。例如,在绪言教学开始要做一些有趣的实验,白纸上喷无色液体能显字,烧不坏的手帕等实验,学生一看化学这么神奇,教师再紧接着追问,为什么会有这些现象?激发学生积极去想,他们学习的积极性大增,进而产生了对化学学科的学习兴趣。

利用化学实验,培养学生的观察能力和思维能力。观察能力的培养是化学实验的重要环节,使学生通过观察实验过程及现象获得生动的感性知识,然后进行积极思维。如,燃烧条件的探究实验,从白磷、红磷在不同环境中的燃烧,通过学生观察分析引出如何保存白磷。探究燃烧的条件等问题,以问题来贯穿整个实验,引导学生积极思考,激活他们的思维,使他们所有潜能和创造性都充分地表现出来。通过长期的训练,学生的观察、思维能力会有质的飞跃。

化学实验的作用不仅仅在于验证和扩展知识、培养能力,更

重要的是为学生走近科学提供一种形式,发展学生的多种能力具有重要意义。如,对“测定空气中氧气的体积分数的实验”通过演示实验后让学生改进,把红磷改成白磷,用一根热的玻璃棒去引燃白磷,这样不在酒精灯点红磷,就避免对空气的污染和实验误差,实验结果更准确。这样既开启了学生心智,还增进了学生的环保意识。化学实验教学也拓展了学生的知识视野。

化学实验在化学教学中可以激发学生学习化学的兴趣和求知欲,培养学生观察、思维分析能力,是化学教学的重要手段。
