语法教学活动课
  发布者:学科专家  发布时间:2012-06-19

一、课堂教学活动目标:1、通过这一教学活动,让学生进一步搞清楚过去分词在句子中的基本用法,并做到基本上能正确使用。2、同时让学生能够比较清楚地区别过去分词和现在分词的不同用法,以免在具体使用时出错。
二、课堂教学活动背景:学生对过去分词使用的单一练习题做起来较容易,错误率较低,但是如果将非谓语动词的使用混合编题让学生去做,很容易搞错。前一天的作业是以训练过去分词的用法为目标的单项选择题,适当混合了考查现在分词用法的选择题。从作业中反映出学生对过去分词和现在分词的不同用法的概念还是不很清楚,因而出现了不少错误。
下面是学生在作业中的一些错误:
1. ________that it was twelve, I turned off the light and went to bed.
A. Find   B. Finding   C. Found  D. To find (正确答案为 B,学生选为C
2. The island, _____ to the mainland by a bridge, is easy to go to.
A. joining   B. to join   C. joined     D. having joined  (正确答案为 C,学生选A
3.  This problem may lead to more serious ones if ______ unsolved.
A. leaving     B. left     C. is left    D. leaves   (正确答案为B,学生选有的选A,有的选C
4. An opportunity is something that, ________, you’ll never get back.
A. if you lose   B. when lose   C. once lost   D. after losing   (正确答案为C学生选A
5. _______ with the size of the whole earth, the biggest ocean does not seem big at all.    A. When compared   B. When comparing   C. Comparing   D. Compare
(正确答案为A,学生选 B
6. The Chinese are proud of Shanghai World Expo _____ in Shanghai in 2010.
A. hold   B. holding    C. held   D. to be held 
(正确答案为C,学生选有的选B,有的选D
7. The question ________ now is very important.
A. discussing   B. being discussed   C. discussed   D. to be discussed
(正确答案为B,学生有的选C,有的选A
8. Coming into the room, I found him_______ into thought, _________my coming in.
A. lost; noticing   B. lost; not noticing   C. losing; noticing   D. losing; not noticing   (正确答案为 B,学生选 D
9. Please remain _______; the winner of the prize will be announced soon.
A. seating   B. seated   C. to seat   D. to be seated
(正确答案为B,学生有的选A,有的选D
10. _________his research for ten years, he made a great achievement at last.
A. Devoting himself to                   B. Having been devoted to
C. Devoted to                          D. Being devoted to
(正确答案为B,学生有的选C,有的选A
从学生的作业中可以得出这样的结论,学生对过去分词done与现在分词doing所表达的被动与主动概念搞不清楚;对doing done作状语、定语、宾补和表语时,它们分别与句子主语,修饰语,宾语之间的逻辑关系为主动还是被动关系搞不清楚;对to be donebeing done done作定语时在时间上的差异没搞清楚;对与主语之间逻辑上为主动关系时的doinghaving done,被动关系时的donebeing donehaving been done作状语时,因时间上的不同有着表达上的差异没完全搞懂。
三、课堂教学活动过程:笔者认真分析了学生的错误所在,其主要原因是分词用法的基本概念还没完全理解和记住,所以需要先澄清概念,在完全理解的基础上,加强用法记忆,再通过做题训练,最终掌握。但是概念的澄清光靠教师讲,不能解决问题,因为有关非谓语动词的用法笔者在以前的课堂教学中已经讲得很清楚,学生听起来似乎都懂了,但实际应用中问题还是不少,如果再讲恐怕效果不好。所以,这节课笔者改变了先讲解的方法,采取提供典型例子,让学生自己阅读,仔细领悟其中规则。
1、呈现例句:(通过PPT呈现)
1. Hearing the news, he jumped with joy.
2. Having finished his homework, he went to bed.
3. Seen from the top of the tower, the south foot of the mountain is a sea of trees.
4. Having been shown around the factory, we went to visit a school.
5. Being mended, the highway is closed to traffic.
 
1.The man standing over there is my brother.
2. The old bridge made of stone was built in the Tang Dynasty.
3. The house being built over there is mine.
4. Many building in the city need repairing, but the one to be repaired first is the library.
 
1.      Dont have the lights burning when there are no people in the room.
2. I found the glass broken when I entered the room.
 
1. Im puzzled about what to do next.
2. The situation was more puzzling than ever.
2、默读领悟:3分钟
3、相互讨论:2分钟
4、信息反馈:2分钟
以上出示的例子,分别是:分词短语作状语的各种形式,其中表示主动概念的有两种形式,被动的有三种形式;分词短语作定语,表示主动概念的只有一种形式,而表示被动概念的有两种形式,再补充了动词不定式被动式作定语;分词短语作宾补;分词短语作表语。让学生在所掌握的有关过去分词和现在分词的知识基础上,自己仔细阅读以上句子,从形式上的不同进一步理解它们在意义上的差异。让学生通过观察、自我理解、相互讨论、信息反馈、最后达到真确理解。
在以前的教学中我往往把动词不定式与分词作状语、宾补、表语、定语时的差异放在一起作比较,由于内容太多,学生很难掌握,一下子被搞糊涂了。所以,现在我只加了个to be done ,其它动词不定式与分词的用法差异暂时不说,待学生对分词掌握了比较好后,再作归纳。
5、背诵记忆:3分钟
6、订正错误:5分钟
    让学生通过刚才的理解和记忆,掌握基本规则,然后,再通过所掌握的基本规则,自己对作业中的错误作自我订正。再相互检查,看是否认识一致。然后,教师抽查,作最后订正。对有些学生还没有搞清楚的,让已经做对的学生作解释。
7能力提高:对于高中学生来说,记忆和模仿能力逐渐减退,理解能力不断提高,所以,他们对外语的学习有别与对母语的学习,需要通过理解记忆掌握语法规则,在此基础上再进行大量的听、说、读、写训练,才有望习得这门外语。在学生对基本规则搞清楚后,我安排了以下作业训练,以提高学生对该语言项目的应用能力。
1)句型转换(通过PPT呈现,共11题,让学生进行口头改写训练,以检查学生是否真的掌握了分词的基本用法,同时,也让学生知道定语从句和状语从句与非谓语动词短语有时可以互换使用。)5分钟
By 1820 the population of New York had grown to about 125,000, which made it the largest city in the USA.
2. This attracted many pioneers who hoped to become rich through the gold business.
3.The swimming pool which had been built by the end of last year came into use last month.
4.The bike which is being repaired is mine.
5.The highway which will be built next year will do good to us.
6. Many people today make choices about their eating habits which are based on what they believe.
7. Organic vegetables are those that are grown without chemicals harmful to human beings or the environment
8.The vegetable which is being cooked is bean.
9. As she saw nobody at home, she decided to leave a note.
10. When we had cleaned the rooms, we began to weed the garden.
11. Because we didnt know his telephone number, we couldnt get in touch with him.
 
2)句子翻译(先口头作业,再笔头落实,当堂订正)15分钟

8、短文填空:(请用括号内动词的适当形式填空)5
作为预备内容,根据学生对课堂内容掌握的情况而定,如果学生对以上各个教学活动配合的比较好,均能顺利完成,就有时间来完成以下内容,如果完成不了,就放着作为课外作业完成。(打印给学生)。
Ladies and gentlemen,
Welcome to our island. I feel it a great honor to be your tour guide here. I’d like to take this opportunity to give you a brief introduction of our island.
As is ______(know) to all of you, we live on an island __________ (surround) by waters. The waters ________ (surround) the island are deep blue. The air on the island _________ (take) in by you is fresh. The ________(drink)water is clear and clean. The scenery __________(attract) visitors is naturally beautiful. It is a good place for us to live in and also a good place for visitors to spend their holidays.
   The first people to come to the island were my ancestors who came from the mainland of our country.
It has been handed down from generation to generation by story-tellers that they were the people ________( dare) to do pioneering work. When they came to the island, it was a lonely island_______(have) no houses but __________(overgrow) with weeds. However, it was not long before it became a good living environment because of the hard work________(do) by them. So I admire my ancestors very much, for they created such a good place for us to live in.
When ______(stay) on the island for a few days, you will be ________( interest)in everything here and don’t want to leave. You will find people here ________(get) on well with you, food here _______(taste) nice and the scenery here really ______(attract) you. You will find nothing ________(worry) about and find all of people here _______(treat) each other with respect and consideration.
Thank you for your listening. May you have a lot of fun here!
通过短文填空,让学生根据上下文意思填出动词的正确形式,学会在语篇中正确表达本节课所复习的语法点,让语法教学语境化。
9、课外作业(完成练习册语法作业,具体内容省略)
四、课堂教学活动小结:这节课改变了教学策略,努力发展学生的自主学习能力。同时,更多地从学生实际出发,让学生有足够的时间对所学内容进行消化记忆,再训练。这节课自我感觉良好,学生能够准确理解所教语法点,并能有效完成所提供的训练任务,达到了预期的教学目标。但是,如果最后能留出几分钟时间,让每位学生当堂用2-5个分词结构描述自己生活中的所见所闻及所做之事,然后,当堂呈现。这样将语言学习与生活实际结合,效果可能会更好。
在今后的课堂教学中我将会坚持六字方针:“自主、合作、探究、主动、多向、和谐”。我相信在老师的指导下,经过自己的不断探究,一定会使教学更上一个台阶。
