五．升华和凝华

[知识提要]

1．升华和凝华：物质从固态直接变为气态叫做升华；从气态变成直接变成固态叫凝华。

2．升华吸热，凝华放热。

3．分析生活中的升华和凝华现象，要特别注意：在许多情况下，物质在固态和气态之间发生转化时，往往要经过液态这个“中间”过程，这些都不是升华和凝华。

2.八年级物理同步练习题 篇二

等资源, 以看代做, 别人替代。后者效果比前者固然大有进步, 但学生自主、探究又落到了一边。两者都不能体现新课程的理念。如何搞好八年级的物理实验教学, 下面谈谈自己的见解。

一、切实转变观念是搞好实验教学的保障

新课程的核心理念是“一切为了每一位学生的发展”, 要促进学生的终身发展, 反映在自然学科的教学中, 就是培养学生的能力, 开发学生的智力, 掌握科学探究的方法, 这也是改变高分低能、培养创新和实践能力人才的有效对策。

要实现能力的培养, 教师要认真学习构建主义的理论, 真正落实学生的主体地位, 参与到学生中。在学生旁边引导, 指导学生通过自主、合作、探究获取知识, 提高能力, 掌握方法、培养精神, 越俎代庖或只看不练, 都不是好办法。要克服“怕”的思想, 一不要怕学生操作不到位, 浪费时间;二不要怕出现意想不到的新情况。

二、大力开发资源是搞好实验教学的关键

要开展实验教学, 设备不足是主要问题, 但并不是“粉笔实验”的借口。设备不足主要靠学校添置, 但这无法在短时间解决的问题, 当务之急是自己想办法。教师在备课中, 要认真调查, 细致寻找, 开发资源。钢尺、塑料尺、口琴、竖笛、木梳、橡皮、激光笔、眼镜、复读机等都可成为实验器材。一只圆珠笔也可以在传导实验中派上大用场。“世上无难事, 只怕有心人。”让学生走出去听一听, 对“噪声”的学习就会很有实效。

其次, 要注意易做的实验、重要的实验要让学生人人会做;难做的器材不容易找, 教师演示给学生看, 最好还是让学生操作演示给学生看, 以使学生充分体验, 充分感悟。原有的实验器材能用的要用, 能改造成新的要改造着用, 寻找替代品变着法子用。只有这样, 学生的动手能力才会大大提高, 才能培养出爱科学、创造科学的人才。

三、合理利用远程教育资源是提高实验教学的途径

实施远程教育给我们带来了大量的优质资源, 令学生耳目一新, 有强大的吸引力。但由于取代不了学生动手, 且对实验设计、操作的自主能力培养也有不利的地方, 因而教师不能完全依赖其进行教学, 要合理地利用它。其中的实验, 可以放在学生动手之前或之后, 起引导或拓宽、落实的作用, 可以大大提高教学质量。

新的课程教学有很多问题需要我们去探究, 实验教学也只有在我们不断探索中去完善, 只要我们真正的落实对学生动手能力的培养, 就一定能实现新课程的目标要求。

(A)

New York is a very large city with 8 million people. How do so many people move about the city on their way to work and school? So, we should know something about its transportation.

In New York you can travel about the city by subway, bus, taxi and car. The subway runs on the railroad lines under the city. It crosses the city at different points and goes all parts of the city. Traveling by subway is the fastest way to get around the city.

The second way to travel around the city is by public bus. It’s a slower way to travel. This is because the bus moves in road traffic which is often heavy.

You can also travel around the city by taxi. This is the most expensive way, but the taxi will take you to the very place you wish to go to. If traffic is heavy, the taxi will be slow. During the mornings and afternoons, this is the “rush hour”. This is the time when the traffic is very heavy with people going to and from work.

The last way to get around New York is using your own car. However(但是), it’s not easy for you to drive, especially(尤其是) when you are driving in the “rush hour”. If there is an accident(交通事故) on the road, you will have to wait for a long time.

The best time to travel around the city is from 9am to 4pm. This is the time after the morning “rush hour” and before the evening “rush hour”. Traffic will be less crowded because most people are already at school or at work.

1. This passage is mainly(主要) about ____.

A. the weather of New YorkB. the transportation of New York

C. the people in New YorkD. traffic accidents in New York

2. The fastest way to travel in New York is by ____.

A. subwayB. taxiC. busD. car

3. The most expensive way to travel in New York is by ____.

A. subwayB. taxiC. busD. car

4. The phrase “rush hour” in this passage means “____” in Chinese.

A. 比赛中的冲刺时刻B. 一小时内所跑的路程

C. (上下班)交通高峰时刻D. 匆匆忙忙的一小时

5. If you travel in New York in your own car, which of the following is the best time? ____.

A. From 8am to 10amB. From 3am to 10pm

C. From 3am to 5pmD. From 10am to 3pm

(B)

Many people like to travel by plane, but I don’t like it because an airport is usually far from the city. You have to get there early and wait for hours for the plane to take off(起飞) and it is often late. You can’t open the windows. You can’t choose the food. Planes are fast, but it still takes you hours to go out of the airport and into the city.

I like traveling by train. I think trains are safe. Railway stations are usually in cities. When you are late for a train, you can catch another one. You can walk around in the train and open the windows. You can see many interesting things on your way. I know it takes a little more time.

I also like cars. You can start your journey when you want to, and you don’t need to go to a railway station or a bus stop. Also you can carry many things with you in a car. But sometimes there are too many cars on the road.

8.八年级物理同步练习题 篇八

大部分同学在学过新知识之后，都觉得自己对这部分知识没有问题了，但是一做题就遇到很多问题，为了避免这种现象，编辑老师整理了这篇，希望大家练习!

1.生活在不同文化背景中的人，会有不同的待人处世的方式。例如：当受到别人赞许自己穿着漂亮时，中国人会习惯于如何对答()

A.谢谢您的赞赏B.您也一样漂亮C.您过奖了D.好，谢谢

思路解析：此题的考查点是“世界文化的丰富性和多样性”，属于对基础知识的考查。做此题必须弄清楚：不同文化背景下，人们的生活习惯和待人处世的.方式是不一样的。

答案：C

2.下列对“世界文化”理解正确的有()

A.世界文化具有丰富性和多样性

B.不同民族和国家的不同文化，有着各自的代表人物，他们又把本国和本民族的文化推向世界

C.每一种文化都有自由存在和发展的权利，不同民族的文化都蕴藏着人类文明的成果

D.全球化的趋势必然导致文化的单一和标准化

思路解析：该题重在考查学生对“丰富多彩的文化”的正确理解。世界是广阔的，文化是多元的，世界各个国家和民族都有着自己独特的文化特色。在不同的文化发展过程中，塑造了不同文化特色的典型历史人物。他们是本民族的骄傲，同时他们又肩负着弘扬、拓展本民族文化的重任。我们每一个人在认识世界文化的过程中，既要弘扬本民族的文化，又要尊重其他国家和民族的文化成果，而不能搞文化的单一化。

答案：ABC

3.当前国内许多青年对一些国外节日(如圣诞节、情人节)津津乐道，并且热烈庆祝。而对一些中国的传统节日(如重阳节、端午节)却差不多被淡忘了。对此，我们应该()

A.全盘吸收外来文化

B.通过立法禁止过外国的节日

C.大力弘扬中国的优秀文化传统

D.固守中国的习俗

思路解析：多元的世界文化，开阔了我们的视野，丰富了我们的生活。但在走向世界的同时，我们千万不能迷失自己，不能失去自身的独特性，而要珍惜自己的精神家园。学习外来文化，不等于照抄照搬，而要批判地继承。对于当今广大青少年热衷于外国节日而淡漠本国传统节日的现象应引起我们的高度重视，应加强对青少年的思想道德教育，大力弘扬中国的优秀文化传统。

热爱自然，但不应妄自菲薄

--对课文《敬畏自然》的一点质疑

近日读了人教版《语文》八年级下册中的课文《敬畏自然》，对作者极度热爱自然的虔诚十分敬佩。文章提出了所有生物平等、人类要像爱护自己一样爱护自然等观点，不乏理据，而且语言幽默优美。然而，文章里面的一些议论难免让读者感到过于偏激，对人类的能力作出了过分而不太必要的贬低。

作者认为：看着人类狂妄的表现，大自然一定会窃笑--就像母亲面对无知的孩子那样地笑。文章对人类为自己的一些高科技而沾沾自喜大肆讥讽。但笔者觉得，人类有理由为自己创造的成就而高兴，就算是“沾沾自喜”也不为过。人类从野蛮走向文明，可谓白手起家，祖先们在极度恶劣的环境中风餐露宿，披荆斩棘，凭借不屈的精神创造了一个又一个奇迹。我们作为其子孙后代，没有理由也没有资格以“大自然”的身份，来贬低蔑视前人创造的辉煌，把自己形容成“无知的孩子 沙陇中学八年级语文科期末考试模拟试卷（中）”更是不必要的“谦卑”。即使如作者所言，大自然是母亲，人类是小孩，难道母亲不会为孩子哪怕是一丁点进步而高兴？有哪位母亲为孩子的成绩和抱负而感到可笑的？现在教育界十分推崇赏识教育理论，道理是应该让孩子为成绩而自信，同理，人类通过自身努力，为改变自己的命运不断进取，其成绩来之不易，当然应该高兴、值得自信，而绝不应该被认为狂妄。

后文的一个观点显得更莫名其妙：“人类的知识与其祖先相比诚然有了极大进步，似乎有嘲笑古人的资本；可是，殊不知对于后人而言我们也是古人，一万年以后的人们也同样会嘲笑今天的我们。”这个看似非常辨证的“历史观”，本人却觉得十分幼稚，甚至有违历史发展规律。纵观人类历史，无论是从猿到人，还是从古人到今人，人类的知识、经验与技能都是一点一滴地累积、一代一代地传授下来的，没有前人的探索经验、失败教训，就不会有今天人类的成就。如果我们每一代人都像作者所说的那样“忧谗畏讥”、不思进取，想必人类社会是不会进步的。尽管我们的科学可能会被一万年后的人们看作幼稚，但我们都必须继续 “幼稚”，继续在任何未知的领域探索真理。惟有这样，人类社会才有进步，才有机会被后人“嘲笑”。中国古代的四大发明和今天的“神舟五号”升空相比，其进步程度无疑是不可同日而语，但谁会觉得当初先人的发明是幼稚无知的呢？

也许是作者太注重别人的看法了，无独有偶，作者还考虑到了宇宙其他高等生物对人类的嘲笑。“即使我们中间的那些伟大人物，在他们（宇宙高等生物）看来也不过尔尔。”这显然是“莫须有”的批评。我们中间的伟大人物，在任何时候都应该受到我们的景仰和尊重，是不得拿来开玩笑的。我们为作者写出这种“长别人志气、灭自己威风”的话而感到耻辱和有损尊严。即便有外星人比我们厉害，我们只有摒弃“崇洋媚外”的心理，才有可能同心协力超越对手，此时我们尤其需要伟大人物；况且，笔者从不认为我们需要苦苦追寻从未发现过的想像中的“外星人”，科幻小说可以凭想像去描绘他们如何厉害，但我们犯不着为也许根本就不存在的智慧生物而杞人有天，我们更不必为他们的可能存在而那么温顺谦卑地自贬。

最后，尽管《敬畏自然》的作者呼吁人类热爱自然、保护自然，立意是好的，然而笔者认为，自然可敬，但不可畏。人类是地球上当之无愧的“万物之灵”，可以用自己的智慧充分掌握自然规律，利用自然、开发自然、保护自然，从而最终保护自己。只有这样，人类才算摆正了自己的位置，才能以主人翁的精神立足自然、爱护自然。不知作者以为然否？

2．本文对《敬畏自然》一文的哪些观点提出了置疑？请用浪线在文中勾画出来。

3．本文段的作者对《敬畏自然》给予了哪些肯定的评价？
