oppose，object和resist
三者都含有“反对”的意思，但是用法有区别。
oppose为常用词，指“对某人、某事采取积极行动来反对”，着重动作，尤指“反对一种观念、思想、计划等”。如：

Ithappens/happenedthat－clause...碰巧……
occur/happen＋to(prep.)．..发生在……

resultin的意思是“产生，导致”，与cause或leadto同义，其主语是起因；in的宾语是结果。resultfrom的意思是“由……引起，产生”，与liein，asaresultof和becauseof同义，其主语是结果，from的宾语是起因。

雨水把大量的泥沙冲下山坡。
(3)Hecollectedquantities(aquantity)ofoldpictures.

(4)Thereisonlyasmallquantityofwineleft.只剩下很少一点酒了。

quantitiesof＝aquantityof，意为“大量的”，既可以修饰可数名词，也可以修饰不可数名词。quantitiesof无论修饰可数还是不可数名词，后面的谓语动词都用复数。
另外，quantity前面还可以加修饰成分，构成的短语有acertainquantityof(一定数量的)，alarge(great，good)quantityof(大量的)，asmallquantityof(少量的……)，large(great，good)quantitiesof(大量的)，smallquantitiesof(少量的……)。

(1)quantity量，数量。如：

Thegovernmenthasbeenbuyingsilveringreatquantities.
政府一直在大量购进白银。
(ingreat/smallquantities意为“大/少量”，用作状语。)
(2)表示“大量的”时，可用以下形式：
①修饰可数名词
many，agreat/largenumberof，great/largenumbersof，agood/greatmany(后面没有of)，manya(后接单数名词，其谓语动词也用单数形式)
②修饰不可数名词
much，agreat/largeamountof，great/largeamountsof，agreat/gooddealof
③既可以修饰可数名词，也可以修饰不可数名词
alotof＝lotsof，aquantityof＝quantitiesof，amassof＝massesof，plentyof(前面没有a)
▲这些短语均常被形容词修饰，如：alargenumberof，asmallamountof，agreatquantityof。
▲quantitiesof/amountsof＋不可数名词＋复数动词；alotof/lotsof/plentyof＋不可数名词＋单数动词。
▲inamount/amounts/quantity/quantities/number意为“在数量上，大量地”。

Evenifyouareagoodhigh－jumper，youjumpnomorethanthreemeters.
即使是个优秀的跳高运动员，你也跳不过三米。
Weshallgo，evenifitrains.就是下雨，我们也要去。

evenif有“虽然、即使、尽管”的意思，引导让步状语从句，可以与eventhough互换，语气比although和though强，可以放在主句前面也可以放在主句后面。

though，although引导让步从句的用法：
though，although引导让步从句时，后面的从句不能有but，但是可以用yet。如：
Althoughitsraining，theyarestillworkinginthefield.
虽然在下雨，但他们仍在地里干活。
Heisveryold，buthestillworksveryhard.
虽然很老了，但他仍然努力地工作。

?Step5　Sentencefocus
1．...butitisarapidincreasewhen_compared_toothernaturalchanges.(P26)
……但是，同自然界的其他变化相比，这种升高是迅速的。
这是一个省略句，补全之后是．..butitisarapidincreasewhenitiscomparedtoothernaturalchanges。
一般说来，省略现象多出现在下列五种状语从句中：
(1)由when，while，as，before，after，till，until，once等引导的时间状语从句；
(2)由whether，if，unless等引导的条件状语从句；
(3)由though，although，evenif，whatever等引导的让步状语从句；
(4)由as，than等引导的比较状语从句；
(5)由as，asif，asthough等引导的方式状语从句。
上述状语从句在省略时，并非任何成分都可以省略，而是遵循以下原则：
(1)当状语从句的主语与主句的主语一致时，可以省略状语从句的主语和系动词be，这时从句中可出现如下结构：
①连词(as，asif，once)＋名词。如：
Once(hewas)aworker，PangLongnowbecomesafamoussinger.
庞龙曾经是个工人，现在成了一位著名的歌手。
②连词(though，whether，when)＋形容词。如：
Workhardwhen(youare)young，oryoullregret.
趁年轻要努力学习，要不然你会后悔的。
③连词(whether，asif，while)＋介词短语。如：
Helookedeverywhereasif(hewas)insearchofsomething.
他到处看似乎在找什么东西。
④连词(when，while，though)＋现在分词。如：
While(hewas)holdingtalkswithPresidentHuJintao，USPresidentGeorgeW．BushthankedChinaforitsimportantroleintheSix－PartyTalks.
在与胡锦涛主席会谈时，美国总统布什感谢中国在六方会谈中起的重要作用。
⑤连词(when，if，evenif，unless，once，until，than，as)＋过去分词。如：
Theexhibitionismoreinterestingthan(itwas)expected.
这次展览比被预料的有趣得多。
⑥连词(asif，asthough)＋不定式。如：
OlympicgoldmedalisthurdlerLiuXiangopenedhislipsasif(hewere)tospeak.
奥林匹克金牌获得者跨栏运动员刘翔张开嘴，好像要说什么。
(2)当从句的主语是it，谓语动词中又含有系动词be时，可以把it和系动词be一起省略。此时构成连词(if，unless，when，whenever)＋形容词的结构。如：
Unless(itis)necessary，youdbetternotrefertothedictionary.
如果没有必要，你最好不要查字典。
2．There_is_no_doubt_thattheearthisbecomingwarmer...(P26)
毫无疑问地球正在变暖……
在Thereisnodoubt后常可跟that引导的同位语从句(在肯定句中，doubt后面有时可跟whether引导的从句)。
Thereisnodoubtthatyouwillsucceedifyoutryyourbest.
毫无疑问如果你尽最大努力你一定会成功。
Thereisnodoubtthathewillcomeontime.他一定会准时来。
类似常用结构：
Thereisnoknowing/telling...没法知道/说……
Thereisnoneed...没有必要……
Thereisnoquestion...……是没有问题的。
Thereisnoreason...没有理由……
Thereisnopossibilitythat...……是没有可能的。
Itisno/smallwonderthat...(Nowonderthat)．..难怪……
Itisawonderthat...……真奇怪/真是令人惊奇。

教学过程

一、导入新课

鲁迅先生在《汉文学史纲要》中曾经这样评价一位古人：“其文则汪洋辟阖，仪态万方，晚周诸子之作，莫能先也。”这位作家是谁？成语“望洋兴叹”“贻笑大方”又出自他的哪篇文章？

（学生回答）

明确：庄子《秋水》板书课题引入课文

二、简介《庄子》并解题

学生介绍后，教师点拨补充：

庄子名周，战国时期宋国蒙人，大体与孟轲同时或稍后。他继承并发展了老子的思想，是道家学派的重要代表人物，与老子并称“老庄”。

《庄子》一书，汉代著录为五十二篇，现存三十三篇。其中《内篇》七篇，通常认为是庄子本人所著；《外篇》十五篇，《杂篇》十一篇，有庄周门人及后来道家的作品。

庄子的思想属主观唯心主义体系。他片面夸大一切事物的相对性，否定客观事物的差别，在认识上走向相对主义。庄子对待生活的态度是一切顺应自然。在政治上主张无为而治。

庄子的文章，想像奇幻，构思巧妙，善用寓言和比喻，文笔汪洋恣肆，具有浪漫主义的艺术风格。鲁迅先生在《汉文学史纲要》中曾经这样评价他的文章：“其文则汪洋辟阖，仪态万方，晚周诸子之作，莫能先也。”

《秋水》是《庄子·外篇》中最重要的一篇，它以河伯和海神对话的形式，讨论了“价值判断的无穷相对性”的问题。课文节选《秋水》开头的一段，单看此文，寓意已经有了新的理解。

三、课文分析

1．教师范读课文（提醒字词读音及断句）

2．学生自由朗读课文

3．学生自读课文，交流课前预习时制作的知识卡片

合作小组交流，互相补充、讨论、明确，在此基础上，小组推荐展示1－2名学生的卡片。教师提示重点知识点，师生共同讨论，归纳其用法及意义。

（1）通假字

泾流之大（“泾”通“径”，径直）

不辩牛马（“辩”通“辨”，辨别，区别）

（2）古今异义词

顺流而东行，至于北海（“至于”，是动词“至”和介词“于”的连用，意为“到达”。今仅用作另提一事的连词）

东面而视（“东面”，脸朝东。今指东边）

（3）词类活用

秋水时至（名词“时（季节）”作动词“至”的状语：随季节，按季节）

顺流而东行（方位名词“东”，作动词“行”的状语：朝东，向东）

以天下之美为尽在己（形容词“美”，作介词“以”的宾语，用作名词：美景）

（4）一词多义

（5）句式

闻道百，以为莫己若者，我之谓也（判断句。“用……者，……也”表示判断）

以为莫己若者（宾语前置句。否定句中，代词“己”作宾语前置。）

我之谓也（宾语前置句。助词“之”是宾语前置的标志。）

吾长见笑于大方之家（被动句。用“见……于……”表示被动）

以天下之美为尽在己（“以……为……”是古汉语常见的固定形式，可译为“认为……是……”“觉得……是……”）

吾非至于子之门，则殆矣（“非……，则……”，是副词“非”和连词“则”的配合格式，可译为“（要）不是，就……”）

且夫我尝闻少仲尼之闻（“且夫”，连词。连接上句或上段，用在下句或下段的开头，可译为“再说”“况且”，表示意思推进一层）

（6）出自本文的成语

望洋兴叹：仰望海神而兴叹。原指看到人家的伟大，才感到自己的渺小。今多比喻力量不够，感到无可奈何。望洋，亦作“望羊”，仰视的样子。

贻笑大方：留下笑柄给内行人，让内行的人笑话。贻，遗留。大方，大方之家，指修养很高、明白道理的人。常用作谦词

4．学生齐读课文，研读讨论

（1）引导学生用课文原句回答下列问题

①河伯在什么情况下欣然自喜？

②河伯为何“始旋其面目，望洋向若而叹”？

③河伯为什么认为自己“长见笑于大方之家’？
