九年级英语八单元教案 篇2

【1】be going to + 动词原形

be going to + 动词原形——表示将来的打算、计划或安排。常与表示将来的tomorrow, next year等时间状语或when引导的时间状语从句连用。各种句式变换都借助be动词完成,be随主语有am, is, are的变换,going to后接动词原形。

1) 如果表示计划去某地,可直接用be going to+ 地点

We are going to Beijing for a holiday.

2) 表示位置移动的动词,如go,come,leave,fly等常用进行时表示将来。

The bus is coming.

My aunt is leaving for Beijing next week.

3) be going to与will的区别:

1对未来事情的预测用“will+ 动词原形”表达,will没有人称和数的变化,变否定句要在will后面加not, 缩略式won’t, 变一般疑问句将will提至句首。

Will planes be large in the future?

Yes, they will. / No, they won’t.

2 will常表示说话人相信或希望要发生的事情,而be going to指某事肯定发生,常表示事情很快就要发生。

I believe Lucy will be a great doctor.

3表示意愿用will.

I’ll tell you the truth.

4表示计划、打算要做的事情用be going to, 而不用will, 从不严格的语法角度而言,be going to与will二者可以互换, 但注意:

*There be句型的一般将来时结构为:

There is going to / will be + n... 将会有 ......

*come, go, leave, arrive等常用现在进行时表示将来:

He is leaving tomorrow.

* 在条件、时间状语从句中,一般是主将从现:

If it is fine tomorrow, I’m going/will go on a trip.

一、能力训练及解析:

( )1.There ____going to be a basketball match this afternoon.

A. are B. is C. have D. will

解析: 在there be句型中be与后面的 真正主语 保持一致,a basketball match是单数形式,谓语动词应该使用单数形式,答案:B。

( )2. —Are there going to be any young trees soon?

—Yes, ____.

A. there be B. there is C. there are D. there are going to

解析:问句为Are there…? 其肯定回答为Yes, there are. 答案:C。

( )3.There will be fewer factories,____ ?

A. won’t there B. will there C. isn’t there D. are there

解析:there will be的反意疑问句为won’t there, 但fewer含有否定意义,在反意疑问句中,前面否定,后面疑问部分用肯定形式,答案:B。

二、实战演练

( ) 1.There __________ a meeting tomorrow afternoon.

A. will be going to B. will going to be

C. is going to be D. will go to be

( )2.Charlie ________ here next month.

【2】复合形容词的使用

1. 构成:数词 + 单数名词、数词 + 单数名词 + 形容词(每两词间用连字符 -)

2. 用法:常作定语,用于名词前 , 一般不单独使用。

如:an eight- year-old boy / a ten-metre-tall tree

3. 复合形容词后加复数,表示一类人或物,可独立作主语:Sixteen-year-olds 16 岁的人。

【能力训练】:

( )1.We will have a______ holiday after the exam.

A. two month B. two-month C. two-months

( )2.I think______ can choose their own life style.

( )5.I’d like to spend ________holiday in the country.

A. a two-day B. two-day C. two day’s

【3】if引导的条件状语从句的用法:

1.if引导的条件状语从句

(1)“If从句 + 祈使句”的句子。

例如:If you want to go, please let me know.

If the green light isn’t on, wait for a minute.

(2)“祈使句 +and(or)+ 陈述句”在意思上相当于一个带有条件状语从句的复合句。

注意:A.“祈使句 +and+ 陈述句”可以转化为if引导的肯定条件状语从句,且主语是第二人称。

B. “祈使句+or+陈述句”可以转化为if引导的否定条件状语从句,且主语是第二人称。

例如:Study hard and you will pass the exam. = If you study hard, you will pass the exam.

Hurry up, or you’ll be late. = If you don’t hurry up, you’ll be late.

(考题 (2010重庆中考 )Work hard,________ you may catch up withyour classmates soon.

A.orB. butC. andD. yet

思路解析:本句是“祈使句 +and”的句型,句意为“努力学习,你会很快赶上其他同学的”,and在句中表示承接关系,所以选C项。

2.if从句与主句具有以下特点:

1)当if表示未来的条件时,主句中用一般将来时,从句用一般现在时,即“主将从现”。

e.g. If you can’t come tomorrow, we can hold the party a little later.

明天你如果不能来,我们可迟一点举行宴会。

If it doesn’t rain tomorrow, we’ll go to the Great Wall.

明天如果不下雨,我们就去长城。

2)表示如果某种条件存在,就有可能 / 不可能发生什么事情。

e.g. If you don’t get up early, you will be late for school.

你如果不早点起床,上学就会迟到。

If I play games on it, it will go wrong.

如果我用它玩游戏,它就会坏掉。

3)if从句可放在主句前或主句后,从句置于主句前时,须用逗号与主句隔开,反之则不用逗号。

e.g. If it’s fine tomorrow, we can go out. 如果明天天气好,我们就能出去。

She will be happy if she joins the party. 如果她参加聚会她会很开心的。

I’ll ask the teacher for help if I don’t understand. 如果我不懂我会求助老师的。

【典题分析】:

1.(2010上海)We will have no water to drink ____we don’t protectthe earth.

A. until B. before C. though D. if

[ 答案 ]D.[ 解析 ]if引导条件状语从句,表示“如果”。意思是如果我们不保护地球,我们将会没有水喝。

2.(2011重庆)We will plant trees tomorrow, and I don’t know ___Tomwill come and join us.

A. if B. which C. what D. where

[ 答案 ]A.[ 解析 ]if引导宾语从句,表示“是否,是不是”。意思是我们明天将会去植树,但是我不知道Tom会不会去。

—Do you know if _____finished the work?

—Not yet. If he , he____ will give me a call.

A. he’s, will finish B. he’ll, finishes

C. he’s , finishes D. he’ll , will finish

[ 答案 ]C.[ 解析 ] 问句的if引导宾语从句,表示“是否”,从句要用陈述语序,从答句Not yet. 中可以看出从句应该用现在完成时态,答句的if引导状语从句,要遵循主将从现的规律。

I tried my best to 59 all the words of the speech and practised it over 100 times. 60my mother’s great love, I did well in the contest.

九年级英语八单元教案 篇6

教学重点：1．铁的治炼

2．有关铁的锈蚀以及防护©

教学难点：冶炼铁的原理和含杂质等不纯量的化学方程式的计算。教学过程：

一、金属的存在

1、地球上以单质形式存在的金属只有金、银等很不活泼的金属，其余都以化合物形式存在。

2、工业上把能用来提炼金属的矿物叫做矿石。常见的矿石（括号内为主要成分）有：

赤铁矿(Fe2O3)黄铁矿(FeS2)菱铁矿(FeCO3)铝土矿(Al2O3)黄铜矿(CuFeS2)辉铜矿(Cu2S)

二、铁的冶炼

1、炼铁的原料：铁矿石、焦炭、石灰石

2、原理：

把铁矿石冶炼成铁是一个复杂的过程，其主要反应原理是在高温下，一氧化碳夺取铁矿石里的氧，将铁还原出来（不能说置换出来）：3CO + Fe3O3 2Fe + 3CO2

3、一氧化碳还原氧化铁步骤：①通入CO；②加热；③停止加热；④停止通入CO 【例题】用500t含氧化铁质量分数为70%的赤铁矿，可以炼出含杂质4%的生铁多少吨？ 【评析】题目所的500t赤铁矿含有不参加化学反应的杂质，需先求出其中参加化学反应的氧化铁的质量。

【答案】氧化铁的质量为：500t×70％＝350t 设350t氧化铁能生成生铁的质量为x Fe2O3+3CO高温===2Fe+3CO2

160 112 350t x×（1-4%）x＝255.2t 本题还有另一种解法，根据化学式计算。

三、金属资源保护

1、金属的腐蚀和防护⑴⑵⑶⑷

⑴铁生锈的主要条件是：铁与空气和水（或水蒸气）直接接触。

⑵铁与氧气、水蒸气等反应生成的铁锈（主要成分是Fe2O3·xH2O）很疏松，不能能像铝一样阻碍进一步锈蚀，所以铁制品能完全锈蚀。

⑶防止钢铁生锈的具体方法有：（如果隔绝了空气和水，就能在一定程度上防止钢铁生锈。）

①在钢铁表面涂油、刷漆； ②在钢铁表面镀耐磨和耐腐蚀的铬；

③制造耐腐蚀的合金如不锈钢等。

2、金属资源保护

① 防止金属腐蚀；②回收利用废旧金属；

九年级英语八单元教案 篇7

以新目标九年级上册第一单元为例。本单元标题为How do you study for a test?本单元主要话题为讨论如何学习, 在第一、第二课时以学习为话题, 全面涉及如何学习英语, 如何通过制作卡片, 阅读报纸, 杂志, 广告, 听英文歌曲, 组织英语角练习口语, 用英语通过网络发展各种感官去感知英语。在通过用英语做事, 强调学习过程, 重视语言学习的实践性和应用性。提倡在学习英语的过程中, 避免直接告知, 死记硬背和机械训练的模式。帮助学生发现和分享有效地学习英语的策略, 注重激发学生积极学习英语的情感, 从而使学生建构起综合语言运用能力。所以本单元的课程设置并非简单地学习词汇、句型、语言点。更加侧重强调提高学生有效的学习语言学习途径与方法。鼓励学生根据自己的需要, 选择恰当有效地学习英语的方式, 尽可能的自己创造学习英语的机会。引导学生尽量在真实语境中, 通过体验、实践、参与、探究和合作的方式, 发现语言学习的规律, 培养学习英语的兴趣。逐步掌握语言知识和技能, 在使用英语的过程中加深对语言的理解, 提高运用语言的能力。引导学生明白学习风格因人而异, 并无绝对的优劣之分, 学习者应该结合自己的学习风格探索最适合自己的学习策略。

本单元第三课时中, 通过一位学生学习英语时一开始有困难, 后来通过不懈的努力, 最后在考试中得到A, 并得到老师同学由衷的赞赏这样的故事, 着重强调学习英语需要的坚持不懈的情感态度, 强调学生培养积极向上的学习动机, 浓厚的学习英语的兴趣和大胆实践的精神有利于提高学习英语的效果, 自信心有助于学生客服外语学习中遇到的困难。同时值得注意的是, 教师在教学中这些情感方法, 价值观的渗透其实与教学内容是相辅相成的关系, 情感, 态度价值观的渗透有利于激发学生学习英语知识的兴趣。

本单元第四课时, 内容进一步拓展和深化, 谈及如何解决学生容易遇到的问题, 如人际交往困惑, 如何处理与父母, 同学, 老师的关系。当遇到问题时, 学会交流, 学会善忘, 指导学生千万不要因为小事挫伤美好的亲情、友情、师生情。还谈到在遇到生活, 学习的压力时, 视问题为挑战, 引导学生在学校接受教育是人生重要的组成部分, 作为学生, 应该尽力主动接受各种挑战, 同时面对生活中的各种困难, 也将其视为挑战, 磨炼自己的意志与坚强的品格。这一部分还谈到要有自己的幸福观, 与那些情况比自己还要糟糕却勇于挑战自己并取得成功的人做比较, 激励学生战胜困难的勇气与方法。这一部分即教会学生如何面对生活中的困难, 又很好的引导学生来了解英语在民族地区作为第二语言, 甚至第三语言学习时, 不可避免地要进行各种尝试, 走弯路, 遇到困难是很正常的, 让学生认识到英语学习中表现的情感态度与学习英语的结果有密切的关系, 作为学生应该有积极的态度去克服各种困难。而勇于去克服这些困难才是勇者, 是胜者。

总之, 人际交往智能与语言不仅与有着千丝万缕的联系, 还在很多方面直接或者间接影响语言学习, 对外语的影响则更加明显。积极向上, 活泼开朗的个性有助于学生积极参加语言学习活动, 获得更多学习的机会, 坚强的意志和较强自信心有助于克服外语学习遇到的困难。

作为英语教师, 以语言技能, 语言知识, 人际交往智能, 学习策略和文化意识五个方面共同构成的英语课程总目标, 既注重体现英语学习的工具性, 也体现其人文性;即关注学生发展语言运用能力, 又重视学生发展思维能力, 从而达到有效提高学生的综合人文素养的目的。

摘要：人类语言的重要功能之一是促进人际交往, 人际交往就要涉及到情感态度。而情感态度在很大程度上需要通过语言来表达与传递。英语课程不仅要发展学生的语言知识和语言技能, 而且有责任培养学生积极向上的人际交往智能。
