篇2：九年级上册英语作文范文

铜仁五中 朱静

一、教材分析

1、教材的内容、地位与作用

Project English 是根据《英语课程标准》编写的教材，这套教材通过不断出现的任务和活动，使学生能够用多种手段与他人交流。Unit 3的主题是English Around the world。本单元围绕着世界语言——英语展开。谈到了英语的广泛应用，英语学习的重要性，不同国家应用英语的差异，英语的发展，手势语及英语学习策略等问题。这些话题与学生的英语学习息息相关，让人兴趣说的一个主题。本节课是这个单元中的第三个话题Could you give us some advice on how to learn English well?围绕着英语学习策略展开，由王俊峰学英语有困难引出话题。本课的学习任务源自真实的学习生活，语言学习（Language learning）的谈论也是《课程标准》要求学生达到的功能意念项目之一。本课的学习也为之后的三个section英语学习策略的谈论打下了学习基础。

2、教学目标

初三的学生在英语学习上是有一定基础的，根据《英语课程标准》的五级目标，能就日常生活的各种话题与他人交换信息并陈述自己的意见；能与他人合作，解决问题并报告结果，共同完成学习任务；能对自己的学习进行评价，总结学习方法。结合本课的教学内容，我特制定本课教学目标如下：（1）知识目标

A.课文中出现的新单词：

dare, grammar, copy, notebook, diary, repeat B.课文中出现的新词组

At times, feel like doing, keep a diary C.语法

疑问词加不定式的表达方式（Wh-+to do）D.主要句型

Could you make yourself understood in the U.S.A? I don’t know what to do.You’d better not.I dare not speak English in public.（2）能力目标

学生学习并掌握谈论自己在学习英语的困难，熟练并运用疑问词加不定式做宾语这个语言结构来表达自己的想法，在听的过程中进行说的能力训练。（3）情感目标

A．有学好英语的信心，大胆用英语进行交流。

B．乐于参加课堂中的活动，在小组活动中积极与他人合作，互相帮助，共同完成学习任务。

C.对英语有更深的了解，能体会英语学习的乐趣。（4）德育目标 树立正确的人生观，热爱学习英语。

3、教学重难点（1）重点：

A．学习Wh-+to do 作宾语。B．谈论语言学习的策略。

（2）难点：谈论自己在学习英语中遇到的困难，并向别人提出建议。

二、教法阐述

依据课程改革，英语教学内容转变成为从学生所熟悉和喜爱的话题和场景导入语言在真实生活中运用的知识和技能。因而在教法上提倡由学生亲身体验、实践，通过交流与合作，师生共同参与构建知识过程的探索与发现式教学模式。这一节课，我采取以下的教学方法：

1、任务型教学法

《英语课程标准》倡导“任务型”教学模式，让学生通过感知、体验、实践、参与和合作等方式实现任务目标。因此，我在教学过程中设计了Pre-task，帮助学生了解学习英语的途径并学习本课新单词及词组，为下个任务做准备；While-task，学习1a,独立完成1b表格，做听力练习；Post-task提高学生的综合语言运用能力，共同讨论遇到英语学习困难的提示语。让学生在完成各项任务的过程中获得知识和运用语言的能力。

2、小组活动

《标准》建议要为学生提供自主学习和相互交流的机会，鼓励学生通过体验、实践、讨论、合作、探究等方式，发展学生听、说、读、写的综合技能。因此，我把全班分为八个学习小组，要求学生积极参加小组中的讨论、角色表演等活动。

3、任务评价

在英语教学过程中还要进行形成性评价，培养和激发学生学习积极性和自信心。在教学的各个环节中，都要求学生参与活动，为了鼓励学生积极参加并对在活动中的表现进行肯定，我为学生设计了如下的评分表格： Name

Class

Date Hands Up Right Answer Total

三、学法指导

在英语课程中帮助学生有效地使用学习策略，不仅有利于他们把握学习的方向、采用科学的途径、提高学习效率，而且还有助于他们形成自主学习的能力，为终身学习奠定基础。因此，在教学设计中，我还注意学生学习策略的培养：

1、认知。学生根据需要进行预习，对所学内容能主动复习并加以整理和归纳。

2、交际。学生在真实的情境中，进行交际活动，在完成交际任务的过程中通过感知、体验、实践、参与掌握英语基础知识，发展运用英语进行交际的能力。

3、合作。把班级分成学习小组，在任务活动中，让各位同学积极参与，互相配合，共同完成学习任务。

4、探究。在语法上，不要求学生死记语法规则，而是让学生在反复操练、实际运用中发现、了解并掌握。

让学生通过自我评价，看看自己是否积极参与课堂的活动，以及自己回答问题的准确率，促使他们努力争取进步。Step 1 Warming-up

1、Free talks 用大屏幕显示本节课的课题Could you give us some advice on how to learn English well? T: Today we are going to learn English.We can also say “We are learning English today.”

T: Are you good at English? Do you have difficulty in learning English？

谈到学生学英语遇到的困难，这个贴近学生学习的问题一下子能够吸引学生的注意力。拉近了师生之间的关系。Step 2 Pre-task

1、Learn new words 学新单词

用多媒体屏幕展示一个英语角的图片，对学生说English corner is a good place to improve our oral English.At times I speak English in public, so I dare speak English in public.Can you make yourself understood in public?..并把新单词写在黑板上，反复跟读几遍。

2、Learn grammar “Wh-+to do”,学语法并举例造句。让学生在反复操练中自己发现语法规律，在实际运用中发现、了解并掌握。在预备任务中，学生得到了充分的练习，扩大了学生的语言输入量，扫除了下个环节中的单词和语法障碍。Step 3 While-task

1、利用大屏幕放映课文的插图和问题，播放课文1a部分的录音，第一遍让学生合上书本进行听力训练，并基本能回答问题；第二遍让学生并完成1b表格。

2、跟读1a.Step 4 Post-task

1、Discuss in group “What difficulties do you have?”小组讨论并由组长做汇报

2、Give some advice for them.个人发言。

3、T: Can you use these tips to talk about the difficulties。完成part 3.4、评价。让学生根据自己在课堂上的表现及评分表上的要求为自己打分，小组合计本组总分，评选出课堂的“小英语专家”和“团体冠军”。

Step 5 Homework：书面完成，写的训练。

The result of the survey, write an e-mail/ give him/her some advice on how to learn English well

篇3：九年级上册英语作文范文

一、测定空气中氧气含量实验的改进

在《化学》教科书中的实验2-1 (图1) , 利用红磷燃烧消耗集气瓶中的氧气, 使集气瓶内气压减少, 引起烧杯中的水沿着导管进入集气瓶, 并约占集气瓶容积的51。但在实际操作中, 常常由于装置的气密性、燃烧匙伸入集气瓶中的速度、导管内原来没有水而冷却后有残留水等问题导致实验误差太大, 并且白烟扩散到空气中还会引起大气污染。为此, 笔者将实验进行如下改进。

往标记好刻度 (容积分为五等份) 的试管中放入一团白磷, 用套有瘪气球的橡皮塞塞紧, 浸入烧杯中的热水 (约80℃) 里加热, 使白磷燃烧, 如图2a所示。待燃烧停止后, 将试管放入水槽中的冷水中冷却。待白烟基本散尽后, 将试管倒立于水槽中, 并在水下取下橡皮塞 (图2b) , 试管迅速冷却。由于气压差, 试管内的液面上升, 约占原空间的。

改进后的实验采用易燃的白磷代替红磷, 操作较原实验更方便。利用气球形成密闭系统, 使整个反应都在密闭系统中进行, 有效避免了原实验方法中影响实验成功的诸多因素, 有误差更小、现象更明显、试管冷却更快、无污染等优点。

二、有关质量守恒定律实验的改进

1.《化学》教科书第90页的“活动与探究”之一:

白磷燃烧验证质量守恒定律。课本中的方法是:将套有瘪气球的玻璃管烧热, 再迅速伸入锥形瓶中接触在细砂上的白磷 (图3) , 冷却后再次称量。此方法往往出现白磷燃烧后产生的有毒白烟逸出, 并有外界空气与锥形瓶中空气对流等问题。为此, 笔者对其进行了改进, 方法如下:

将橡胶塞上的长玻璃管改短并套上瘪气球, 在锥形瓶口上塞紧。再将锥形瓶浸入约80℃的热水中引燃白磷 (图4) 。冷却后再次称量。

在该实验中, 白磷燃烧一直在密闭系统中进行, 有效防止了有毒白烟逸出, 避免了锥形瓶内气体与外界气体的交换, 同时还给学生介绍了加热的另一种方法———水浴。

2.《化学》教科书第90页的“活动与探究”之二:

碳酸钠粉末与稀盐酸验证质量守恒定律。教材中的实验意图是:对于有气体产生的反应, 若在敞口体系中进行, 会因气体的逸出而减小质量, 从而引导学生在分析质量守恒定律时要考虑反应产生的气体。但教材若再增补1个在密闭系统中的实验验证, 则更能增加学生对质量守恒定律的可信度。

为此, 笔者设计了如下的增补实验 (图5) :在1个空矿泉水瓶中注入适量稀盐酸, 瓶口上套1个装有少量碳酸钠粉末的气球。反应前称量整套装置的总质量, 再将气球中的碳酸钠粉末倒入稀盐酸中, 充分反应后, 再称量整套装置的总质量, 结果天平仍然平衡。实验时应注意碳酸钠粉末宜少, 气球能鼓起即可。由于中学教学对天平灵敏度的要求不高, 故气球鼓起时浮力因素对实验结果几乎没有影响。

该实验取材容易, 制作方便, 操作简单, 现象明显, 能使学生坚信:只要在密闭容器中进行, 任何化学反应前后所有物质的总质量就不会变。要利用有气体参加或生成的化学反应来验证质量守恒定律, 就必须在密闭系统中进行。

三、倾倒CO2的实验改进

在《化学》教科书中的实验6-5如图6所示, 将收集有二氧化碳的集气瓶沿烧杯边沿慢慢往烧杯中倾倒, 下面的蜡烛先熄灭, 上面的蜡烛后熄灭。这说明二氧化碳密度比空气大, 二氧化碳不支持燃烧, 也不能燃烧。但在具体实验中, 往往由于操作难以把握而造成上层蜡烛先熄灭, 导致实验失败。为此, 笔者对该实验做了如下改进。

如图7所示, 在烧杯内一侧放1块玻璃片, 再从烧杯中背蜡烛的一侧缓缓将集气瓶中的二氧化碳倒入, 即可观察到下面的蜡烛先熄灭, 上面的蜡烛后熄灭。该实验改进虽小, 但成功率高。

四、增补CO的性质实验

《化学》教科书第118页, 关于CO性质教学教材没有安排实验, 教学时常采用纯理论推理或动画模拟等手段, 学生记忆不深。为此, 笔者增加了CO的可燃性和还原性2个实验。

1. CO的可燃性实验。

如图8所示。取下收集有CO的集气瓶瓶塞, 迅速用燃着的蜡烛放在瓶口引燃CO, 观察到明亮的蓝色火焰;燃烧完后, 迅速倒入适量澄清石灰水, 塞紧橡胶塞振荡, 澄清石灰水变混浊即说明CO能燃烧且生成CO2。

2. CO的还原性实验。

将套在橡胶塞上的胶头滴管吸入适量的澄清石灰水, 橡胶塞上插入1根绕成螺旋状的铜丝 (图9a) 。再将铜丝在酒精灯上加热, 使之表面产生一层薄的黑色氧化铜, 并趁热迅速将它连同橡胶塞插入装CO的集气瓶中 (图9b) , 即可观察到铜丝表面由黑色变为红色, 挤入澄清石灰水并振荡, 观察到澄清石灰水变混浊, 取出胶塞, 迅速用蜡烛点燃剩余气体, 防止CO污染大气。

这两个实验操作简单, 说服力强, 现象明显, 学生兴趣浓厚, 实验成功率高。

五、探究燃烧条件的实验改进

在《化学》教科书中, 探究燃烧条件的实验 (实验7-1) 采用如图10a、图10b所示的装置。

在教科书中, 实验装置要求在通风橱内进行, 但在普通教室里或条件较差的学校往往没有通风橱, 按此方法实验, 金属片上即使放少量的白磷, 白磷燃烧产生的白烟污染也无法避免 (图10a) 。用导气管向水中的白磷吹氧气, 实验不易控制, 有时部分白磷会浮于水面而发生燃烧甚至飞溅现象 (图10b) 。为此, 笔者对该实验进行了如下改进。

1. 燃烧条件的探究。

如图11a所示, 在烧杯中加入热水, 用镊子取一小团白磷放入烧杯的热水中, 另取一小团白磷放入1支试管中, 立即套上1个气球, 再取适量红磷放入另1支试管, 同样立即套上1个气球, 分别将2支放有白磷和红磷的试管放入热水中, 观察到试管中的白磷燃烧, 红磷和水中的白磷不燃烧。

2. 燃烧条件的验证。

用1支空试管罩在热水中的白磷上, 发现水中的白磷遇到试管中的空气立即燃烧 (图11b) 。

改进后的实验装置取材方便, 节约药品, 操作简便安全, 现象明显, 产生的污染被充分吸收, 实验时间短, 增强了实验的可信度。

篇5：九年级上册英语作文范文

文字之所以比烟花更璀璨，是因为，我可以看着它在光滑的纸页间静静旋舞，演绎出永恒，浅吟低唱岁月的旋律。

那时，我是班上最不受欢迎的“怪物。在炫烂的阳光下，乌云为我留下了一个孤单的角落。庆幸的是，我没有把自己背弃，我并不是形单影只，还有书，成为我最忠实的朋友。他忍受了我古怪，孤僻的性格，他接纳了我丑小鸭似的脸蛋。

书，一个好温暖，好亲切的称呼，如雨后的太阳闪烁着湿润的光泽，永远令我爱不释手。

在寂寞里，他告诉我“成大事业者必须忍受孤单；失败后，他鼓励我：“就算有一千零一次失败，也要做一千零一次努力；众人的嘲讽，白眼中，他叮咛我“冷静是给羞辱你的人最好的表情……

于是晶莹剔透的文字在一个个夜晚、白天，以金子般细碎闪亮的光芒串连起一个空灵无暇的世界。我以新的最清澈明亮的目光剖析这个天地。我学会了稳重，笃实，开朗而沉静，活泼而严谨。

在人生的冬天，书有一个个灵动的文字融化了南极的冰雪。

当我站在全国作文大赛的颁奖台上，我平静地接过特等奖的证书；当我面对闪烁的镜头时，我平静地举着话筒采访着名主持人董浩、鞠萍；当我抱着琴，在全国五十周年纪念的礼堂里平静地致谢……我已经学会平静地收获，学习。是灯下读书的日子点燃了我一个个梦想。

读书，成了生活的主旋律，成了生命的主心骨，它是生命最简朴的表达形式。
