篇4:语文八年级上第五单元教案学案

人教版语文八年级(上)第五单元教案学案

第五单元 读懂文意 领会内涵

1. 桃花源记

2. 陋室铭 爱莲说

3. 核舟记

4. 大道之行也

5. 望岳 春望 石壕吏

兴趣情境导引

先请同学们读一则故事。

有人丢了一把斧子,心里怀疑是邻居的儿子偷去了。因此,看他走路的姿势,像是偷斧子的;看他脸上的表情,像是偷斧子的;看他说话,像是偷斧子的。总之,看他的一举一动、面目表情没有一样不象是个偷斧子的。没有多久,这人去山谷刨土,找到了失去的斧子。隔了几天又看到了那个邻居的儿子,看他的动作态度,就没有一样像是偷斧子的了。

师:有谁读不懂的吗?

生:没有。

师:再看下面这则故事,有谁读得懂吗?

人有亡斧者,意其邻之子。视其行步,窃斧也;颜色,窃斧也;言语,窃斧也;动作态度无为而不窃斧也。

俄而,其谷而得其斧。他日复见其邻人之子,动作态度无似窃斧者。

生:我发现这两则故事说的是同一件事。

师:有多少人同意这一说法。

尽管第二段故事不能每个字都理解,但多读几遍还是有能读出大意的。

第一则故事就是根据第二段翻译过来的,那么第二段不也是汉字写成的吗?为什么读不懂呢?

生:它是文言文。

师:对,是文言文。是古人写文章专用的语言。(古人说话与写文章用不同的语言。)

学文言文有什么用呢?这么深奥难懂,

因我们中国有数千年悠久的历史,我们的祖先在这历史长河中创造了无比灿烂的文化,为世界文明做出了巨大的贡献。这文化遗产是取之不尽、用之不竭的宝藏,是我们中华民族的骄傲与自豪。我们这些中华民族的子孙,有责任传承这份宝贵的文化遗产,自觉学好文言文,换句话说,为传播文明就必须学好文言文。同时,现代语文是古语文的继承和延续。大量的古人语言仍存活在现代人的语言中,如成语就是明证。因此,要学好现代语文也必须学好文言文。但是要打开这一文化宝藏的大门,想不花力气可不行。其首要条件是必须掌握相当数量的古文,由此循序渐进,才能积累大量的语汇,丰富自己的语言,提高自己的语文素养;才能去阅读那卷帙浩繁的文化典籍,汲取中华文明的精华,进而做人类文明的承载者、传播者。

生:老师,我们都想学好文言文,不知你说的这“相当数量”是究竟有多少?

师:教育部规定初中生必须会背诵文言文20篇以上,古诗词120篇以上,这个数量

师:简单地说,学好文言的基本方法离不开“诵读文章,读懂文意,领会内涵”这十二个字。

生:怎么“诵读”,怎么才能“读懂”,怎么才能“领会”呢?

师:我们就结合第五单元的几篇课文谈吧。

难点互动探索

难点问题1   读懂文意

师:古人学文言的方法很简单,就是一个字:读。他们认为“书读万遍其义自见”。

生:对我们这些初学者来说文言文无异于天书,读读就懂了吗?

师:告诉大家,大量的事实已证明,这确实是学习古文的最好方法。但必须明确的是,我们现在主张的“读”不仅仅是张开口发出声音就行了,它有讲究,讲究会读和读的方法。

生;怎么才算“会读”?

师:“会读”是指:读准字音(读词典),吐字清晰、声音洪亮;读出节奏,停顿正确;读出语气( 陈述、疑问、祁使、感叹),读出感情。

“会读”还指:不光读原文,还要读文下注释,读与原文有关的材料,读文言词典;

反复读原文:在读正确后,要读流畅,再要读出感情,最终成诵以至化为自己的语言;

读原文时,边读边悟,猜测词义、句意,领会上下文意,边读边悟,越读越透,直到领会全文内涵。

生:老师请结合本单元课文具体教教我们读文言文吧!

范例1 怎样读《桃花源记》?

解答:

1.扫清语言障碍,把文章读顺畅。注意几个词的读音:仿佛 俨然 阡陌 髫 要 诣 骥

2.停顿分明,不读破句子。如:“忽逢/桃花林,夹岸/数百步,中/无杂树,芳草/鲜美,落英/缤纷”“问/今是何世,乃不知/有汉,无论/魏晋”

3.用中速,读一遍约2.5分钟。读出语气,读出感情。如:“晋太元中,武陵人捕鱼为业”用陈述语气,平静的叙述故事;“乃不知有汉,无论魏晋”用感叹语气,读出惊讶;“不足为外人到也”用祁使语气,读出诚恳的希望。

4.边读边猜边查边理解,读十遍要基本成诵。

范例2 怎样解释《桃花源记》中有些文言词句、整体把握文意?

分析:

第一段:写渔人忽逢桃花林。

①晋太元中:古代用皇帝年号或天干地支法纪年(如有同学想了解得更详细请查阅有关古文化知识资料),“晋太元中”即东晋孝武皇帝太元年间。

②缘:根据上下文猜测,词义可能是“沿着、顺着”。再查词典验证。《古汉语常用词词典》解释为“循、沿”。确定猜测正确。

下面几个词请你猜猜看是什么意思。

异:认为……奇异       之:它指前述美景即“桃花村……缤纷”

复:又 境:地方

③芳:a香(气),b花(草)。词典有两个义项,选哪个义项合适呢?选“花”,从词的结构上看更好些,“花、草”都是名词,后面的“鲜、美”都是形容词。尽管“香”的意思放在“草”的'前面也说得通,但考虑到后面的“鲜、美”是形容词,就不太好了。

④鲜美:现代汉语中有这个现成的词,但它一般是用来形容食品的味道好的,用这个词义来修饰芳香,显然不通。怎么回事?这就要追究文言文的特点了。在文言文中每一个字都叫文言词,一般讲,一个文言词也应对应现代的一个词。即“鲜”对应“鲜艳”或“鲜嫩”,“美”对应“美丽”。这种解释文言词的方法不妨叫它扩充组词法。

下面的许多词都可以用这个方法来解释。

穷:穷尽    绝:(与世)隔绝    通:通过

开朗:开阔、明朗            交通:交错、相通

篇5:《五柳先生》片段教学案(八年级) 教案教学设计

叶剑    .04.02

一.教学目标

知识方面   体会本文个性鲜明的写人方法。

情感态度    感受五柳先生的性格志趣和精神风貌。

能力方面  培养学生迅速、准确地抓住文中的关键信息的能力。

重点难点分析

二.教学重难点

1.了解人物的性格志趣和精神风貌,体会个性鲜明的写人方法。

2、理解五柳先生“好读书,不求甚解”,是一种读书方法,即读书不死抠字句,而要求真谛。

3.“短褐穿结,簟瓢屡空,晏如也”的含义。

三.教学过程

请同学朗读第一段,思考下列问题 :

1、第一句话讲了什么?

--讲述了“五柳先生”这个名号的来历。

“不知何许人”把这位先生排除在名门望族之外;“五柳先生”之号得来的原因是其宅边有五棵柳树,而人们又不知他是什么地方人,姓甚名谁也木知道,因此便只称“五柳先生”。作者说不知他是谁,其实正暗示指作者本人。   随便起了一个字号,与当时讲究门第的'世风背道而驰,表现了他卓尔不群、不随世俗的品性。

2、文中哪些语句表现了五柳先生的性格、志趣和生活?刻画了怎样的人物形象?

--性格:“闲静少言,不慕荣利”点出了五柳先生的隐者心境。

志趣:一是读书,“好读书,不求甚解”,展现了一个在读书中的精神愉悦的五柳先生;二是饮酒,“性  嗜酒”、“期在必醉”展示了一个率真放达的五柳先生;三是写文章,“常著文章自娱”、“忘怀得失”描述了一个自得其乐、淡泊名利的五柳先生。

生活:“环堵萧然,不蔽风日;短褐穿结,簟瓢屡   空,晏如也”描绘了一个安贫乐道的五柳先生。

通过种种叙述,把一个虽处于贫困之中却悠闲自适的隐士形象活灵活现地刻画出来,赞美了他安贫乐道的精神。

3、怎样理解“好读书,不求甚解”这句话?

--这是一种读书方法,即读书不死抠字句,而要求真谛。也说明陶渊明读书的目的,是一种求知的满足,精神享受,所以“每有会意,便欣然忘食”。他不求名利,只求精神上得到安慰,他的不求甚解是他率真自然性格的反映。

4、怎样理解“短褐穿结,簟瓢屡空,晏如也”的含义?

--不仅写出陶渊明安于贫困,而且含蓄地说明作者以古贤颜回自况,追求高尚的道德情操。可谓含而不露,有弦外之音,非常含蓄。

四.小结

本文借五柳先生给自己写自传,从思想性格、爱好、生活状况等方面塑造了一位独立于世俗之外的隐士形象,赞美了他安贫乐道的精神。

五.版书

I found out one time that doing a favor for someone could get you into a lot of trouble.

I was in the eighth grade at the time, and we were having a final test. During the test, the girl sitting next to me 1 something, but I didn’t understand. So I leaned over her way and __2 that she was trying to ask me if I had an extra pen. She showed me that hers was out of __3 and would not write. I happened to have an extra one, 4 I took it out of my pocket and put it on the desk.

Later, after the test papers had been 5 , the teacher asked me to stay in the room when all the other students were dismissed. As soon as we were 6 , she began to talk to me about what it meant to grow up; she mentioned how 7 it was to stand on your own two feet and be __8 for your own acts.

五、阅读理解 (30’)

A

Men are dirtier than women. Scientists proved it by spying in public restrooms, watching one-quarter of the men left without washing their hands. In contrast, 90 percent of the women did wash up. Many results show the single easiest step to stay healthy is spending 20 seconds rubbing hands with soap under faucets(水龙头). They also explain we should use paper towels to open bathroom doors. There exists the possibility that the person before you left germs(细菌) on the knob(把手).

Back in , the society first studied how often people followed Mom’s advice to always wash up after using the toilet. Researchers stayed in public restrooms a little longer, putting on make-up or combing their hair, while secretly counting. They concluded about one-third of people did not wash.

They also started an education campaign about how hand washing can stop the spread of-the flu, diarrhea(腹泻) and other infectious diseases. Every few years, researchers repeat the investigation.

This time, 83% of people washed, reported Harris Interactive, a research company that last month monitored more than 6,300 public restroom users for the society. That is a little better overall.

People praise themselves about hygiene(卫生). A telephone survey of 1,000 adults found 91% insisted they wash in public restrooms. Additionally, 77% claimed to always wash before handling or eating food, and 32% after coughing or sneezing(打喷嚏).

With the influenza season approaching, microbiologists(微生物学家) warn that it is easy to catch a cold or the flu by shaking hands with someone who just used that hand to cover a sneeze. The viruses can stay alive for two hours on hands, and for 20 minutes on hard, dry surfaces those germy hands touch. So sneeze into your elbow(肘部) instead and wash frequently.

1. The first paragraph mainly tells us that ________.

A. rubbing with soap for 20 seconds can keep healthy

B. paper towels can keep you from germs

C. women will not leave germs on the knobs

D. washing hands is important to us in daily life.

2. From the text, we can learn that _________.

A. half of people didn’t wash their hands during the 1996 study

B. Harris Interactive has engaged in the research for more than ten years

C. people pay more attention to their hygiene now

D. shaking hands is unhealthy and dangerous

3. Why does the author advise us to sneeze into our elbows instead of into our hands?

A. Because this can avoid passing on our flu to others easily.

B. Because we eat with hands, not with elbows.

C. Because a dirty hand is more easily seen than a dirty elbow.

(BBC News April 18) All flights in and out of the UK and several other European countries have been cancelled as ash from a volcanic eruption in Iceland moves south.

Up to 4,000 flights are being cancelled with airspace closed in Norway, Sweden, Finland and Denmark among others.

The UK’s air traffic control service (Nats) said no flights would be allowed in UK airspace until at least 07:00 BST on Friday for fear of engine damage.

Safety group Eurocontrol said the problem could last for 48 hours.

The volcano is still erupting and the wind direction is expected to continue bringing clouds into UK and European airspace for some time to come.

The UK’s airspace restriction was the worst in living memory, a Nats spokesman said.

Some 600,000 people are thought to have been affected.

Nats suggested that the restrictions were unlikely to be lifted(解除) after 07: 00, saying it was “very unlikely that the situation over England will improve in the foreseeable future”.

Passengers were advised to contact their carriers before traveling.

Transport Secretary Lord Adonis said he was “closely monitoring the situation” and would be meeting with key transport officials on Friday morning.

Experts have warned that the tiny particles of rock, glass and sand contained in the ash cloud from the still-erupting volcano could be sufficient to jam aircraft engines.

The Health Protection Agency said the ash from the eruption did not bring a significant risk to public health because of its high altitude.

However, the British Lung Foundation has warned people with lung conditions to keep their medication (医疗护理) with them as a precautionary measure.

These are some of the knock-on effects:

Eurocontrol says Germany is monitoring the situation and considering partial airspace closures.

The two main airports in Paris and many others in the north of France are closing.

There is severe disruption(崩溃) in France and Spain, where all northbound flights are cancelled.

Nats is due to make an announcement shortly as to the arrangements that will be in place through to 13:00 BST on Friday.

British Airways offers refunds or an option to rebook after all its domestic flights are cancelled.

5. What may passengers do on hearing the news according to the passage?

A. They may cancel their international flights.

B. They may contact the airlines before traveling.

C. They may take measures to protect their lungs from the ash.

D. They may stay indoors till the volcanic eruption dies down.

6. Why have some European countries cancelled flights after the volcanic eruption?

A. Because the volcanic ash may make passengers ill.

B. Because people refuse to take the international flights.

C. Because the volcanic ash may jam or damage the engine.

D. Because the flights may be hit by the rocks from the eruption.

7. Which of the following statements is true according to the passage?

A. All the flights are likely to return to normal in 48 hours.

B. British people had experienced a worse airspace restriction before that.

C. Germany is monitoring the situation and considering closing all airspace.

D. The UK airspace restrictions are unlikely to be lifted in the foreseeable future.

The French are living up to their image as lovers of food and can add a new love to the mix, sleep, according to a survey released Monday. In fact, the French outdo the others at the two leisure activities, spending more time at table and in bed.

The Paris-based Organization for Economic Cooperation and Development looked at the use of leisure time among 18 of its 30 member countries.

Norwegians spend the most time at leisure, just over a quarter of their day, while at the low end, Mexicans spend just 16 percent of their time having fun.

The French still win in the sleeping and eating categories, spending on average nearly 9 hours a day in bed. For the French, leisure continues in the waking hours, with more than 2 hours a day spent eating and drinking nearly twice as much time at the table as Americans, Canadians or Mexicans.

Americans also like their sleep, spending some 8.5 hours a day doing just that.

Despite the moderate amount of time Americans spend eating each day about an hour and a quarter U.S. obesity(肥胖) rates are the highest in the 30-member OECD with 34 percent of the American population with a Body Mass Index, or BMI, over the critical 30 mark. The lowest obesity rates are found in Korea, followed by Japan, with less than 4 percent of the population with a BMI over 30.

The Koreans followed by the Japanese clock in at the low end of the sleep time range, getting 7.8 hours a day with the Japanese not far behind.

Television ranks high among leisure activities in Japan where it takes up 55 percent of free time, compared to a low of 25 percent for New Zealanders.

The Turks are the most sociable population. They spend more than 35 percent of their time entertaining, compared to an OECD average of 11 percent.

8. The survey ________.

A. was conducted by people living in Paris

B. used data collected from 18 countries

C. showed relationship between leisure activities and BMI

D. involved every OECD member country

9. How many of the following should be included in leisure activities according to the text?

Sleeping; Eating and drinking; Working; Having fun; Studying; Entertaining people; Watching TV.

A. Four. B. Five. C. Six D. All of the seven.

B. The French (Not told) The French The Japanese Norwegians Mexicans

C. Americans (Not told) The French The Koreans Norwegians (Not told)

D. The French Americans Americans The Koreans Mexicans Norwegians

11. From the last two paragraphs, we can infer that

D. the Turks are the least likely to be alone among the OECD nations

It had been a long time since I had been to Jacksonville, Florida. I had driven to town hoping to see the old barber shop where my hair had been cut as a child.

I parked my truck and decided to try and locate a telephone to see if the Florida Barber College had moved to a new location.

After walking about a block I saw an open shoe store. I walked inside and asked if I could use their telephone book. Unable to find a listing for the Barber College, I picked out the number of a local beauty salon, hoping they might tell me if the barber college was still in business. The number was busy, so I decided to wait and try again in a few minutes.

As the salesman and I stood talking the front door opened and a young man about twenty came into the store pushing himself in a wheelchair. “I need a new pair of shoes,” said the customer. As he turned the corner, there was a blanket across his lap. I was shocked to see that the young man had no legs.

“A gift for a friend?” I asked the boy. “No,” he replied. “They are for me,” he continued, with a smile on his face. I just smiled back and watched to see what would happen next.

“What type of shoe would you like?” asked the clerk. “How about a pair of cowboy boots?” The man pointed to the back wall where three or four pairs of boots were displayed. The salesman, sharply turning, headed off to the backroom.

“Isn’t this fun?” the boy asked me. I moved my hand to let him know that I did not understand his question. “When I was a kid, my parents used to buy me a new pair of shoes every year. That was such a wonderful feeling. Something I have never forgotten. The smell of the leather and the pride I felt when I walked around the store showing off my new shoes.”

The salesman came walking down the aisle with a large box. He sat it down on the floor, took out one boot and handed it to the young man. The boy closed his eyes. He placed the boot against his nose, and drew in a large breath. I did not know what to say as tears began to fall on the young man’s cheeks. “What type of accident did you have?” I asked him. “Farm accident,” he said, as he tried to clear his voice.

“Do you want the cowboy boots?” the salesman asked him.

“Oh, yes!” he answered.

“I see buying a new pair of shoes still gives you that good feeling you talked about,” I told the young man, as I smiled.

“Yes it does.” he said “And I may have someone, and his feet to share it with some day.”

12. Why did the young man want to buy a new pair of shoes?

A. Because he bought a pair every year.

B. Because he wanted to send a new pair to a friend.

C. Because he hoped to keep it for memory.

D. Because he enjoyed the feeling of possessing a new pair.

13. The author writes about the barber shop at the beginning of the article in order to _______.

A. introduce the background of the story

B. see if the Barber College had moved to a new location

C. find a listing for the Barber College

D. pick out a local beauty salon

14. How did the author feel when he saw a young man without legs buying a pair of shoes?

A. Unexpected. B. Proud. C. Sympathetic. D. Superior.

15. What can you conclude from the passage?

A. The young man was a stubborn person.

B. The author was a man of understanding.

C. The cowboy boots were fashionable then.

D. The disabled envied much those healthy.

六、任务型阅读(10’)

This year, about 2,300 teenagers from all over the world will spend about 10 months in US homes. At the same time about 1,300 American teenagers will go to other countries to learn new languages and learn the rest of the world.

Here is a 2-way student exchange in action .Fred,19, spent last year in Germany with George’s family. In turn, George’s son Mike spent a year in Fred’s home in America.

Fred, a lively young man, knew little German when he arrived .But after 2 months of studying, the language became easy for him. School was completely different from what he had expected and it was much harder. Students rose respectfully when the teacher entered the room. They took 14 subjects instead of 6 that were usually taken in the US.

Family life ,too, was different. The father’s word was the law. All the activities were done with the family rather than individually .Fred found the food to be too simple at first. He also missed having a car.

“Back home ,you pick up some friends in a car and go out to have a good time .In Germany, you walk but you soon learn to like it .”

At the same time, in America, Mike ,a friendly German boy, was also forming his own ideas. “I suppose I should criticize American schools” he says , “It is far too easy for our level but I have to say that I like it a lot In Germany, we do nothing but study. Here we take part in many other activities. I think that maybe American schools are better than in training their citizens. There ought to be some middle ground between the two.”

Writing a report

Planning

Ask students to work in small groups. First let them discuss the questions and then ask them to decide on a topic for their report. Make sure that each group chooses a different topic. Then they should discuss the tasks and decide which group members will be responsible for each task. Set a deadline for the project.

Preparing

Ask students to sort the information they have got from various sources. Then they should meet, discuss and decide what to include in their report. Those responsible for writing an outline should organize the information and write an outline for the report. They may refer to Step1 and 2 for some information . When finished, the outline should be approved by all the group members.

Producing

Group members who are responsible for writing the report should write it based on the outline. All group members should edit the report, paying attention to some aspects listed. Then they should proofread it at least once, correct and mistakes and add more new ideas.

Presenting

Each group should rewrite the report and review it. After checking once more for mistakes, each group presents their report to the class. Finally, each group puts their report on the display wall of the classroom for everyone to see.

第三部分 语法学习

本单元重点语法是复习不定式和动名词的用法。要点如下:

一、动词不定式

1. 常用形式:一般主动式to do,

一般被动式to be done

完成主动式to have done,

完成被动式to have been done

进行式to be doing

2.语法功能:可作主语、表语、宾语、宾补、定语和状语(即除谓语之外的各种成分)。例如:

1) 主语:To master a foreign language is very important.

2) 表语:My job is to drive them to the company every day.

3) 宾语:Do you want to visit the Great Wall?

Can you give us some advice on what to do next?

4) 宾补:The teacher advised us to have a rest first.

I didn’t notice them come in.

注:see, hear, watch, notice, have, make, let等动词后作宾补的动词不定式不带to, 但变为被动语态以后(即不定式作主补时)要带to。

help(帮助)后作宾补的动词不定式可带to,也可不带to, 即help sb.(to)do sth.

5) 定语:不定式位于所修饰的名词,代词之后,

Who was the first one to get to the top of the hill yesterday?

He is the man to depend on/to believe in.

6)状语: in order to

A.目的状语:She reads China Daily every day so as to improve her English.

to

注:in order to 可以位于句首或句中,so as to 不能位于句首。

B.原因状语: I’m glad to see you .

注:这种“be+形容词+不定式”结构,其不定式有时也可视为宾语,

如:He is eager to go to college.

She is sure to come here.

C.结果状语:They lived to see the liberation of their home town.

△在“too…to…”结构中表“太…结果不能”,如:He is too weak to do the work.

注:too之前如果有only, only too 表“非常”、“很”意,此时不定式不再表否定意,而表肯定意。如:They are only too lucky to go abroad for a visit. 他们很幸运去国外访问。

另外,too后如果是happy, glad之类形容词时,不定式也表肯定意义。

如:She was too happy to meet her old friend in the street.

△在“形容词/副词+enough+不定式”结构中表“足以能…”,如:He is strong enough to do the work .

3.复合结构不定式(for sb. to do sth.),可作主语、表语、宾语、定语和状语。for 本身无意义,sb.可称之为不定式的逻辑主语。例如:I think it necessary for him to go there at once.(复合结构不定式作宾语)

注:当作表语用的形容词表示不定式的逻辑主语的性质或特征时,不用for, 而用of,

如:It is kind of you to help me .(相当于You are kind to help me .)这类形容词有good, nice, kind, wise, clever, foolish, silly, stupid, careless, impolite(不礼貌)等。right, wrong既可用于for sb. to do sth. 也可用于of sb. to do sth. 例如:It’s right/ wrong for/of him to do the work alone.

4.疑问词+不定式:可作主语、表语或宾语。如:How to finish the work in time is a problem.(主语)We don’t know when and where to go .(宾语)

5.动词不定式的否定式(not to do sth.),语法功能同不定式肯定式。

6.不定式的时态形式所表示的时间关系:

1)一般式:表示的动作和谓语动词所表示的动作同时发生,或在谓语动作之后,或

没有时间限制。例如:

They often watch us play table tennis.(与谓语动作同时)

She hopes to go there again.(在谓语动作之后)

It is necessary and important to read English every day.(无时间限制)

The factory to make radios is over there.(无时间限制)

2)完成式:表示的动作在谓语动词所表示的动作之前。如:I’m sorry to have kept you waiting. /She seems to have been a teacher for many years.

3)进行式:表示正在发生的动作且与谓语动作同时发生。例如:

She happened to be writing a letter in the room when I came in.

7.不定式的被动式:名词、代词为不定式的逻辑宾语时,一般用不定式被动式。

例如:What is to be done is unknown. /The bridge to be built there is very long.

二、动名词

1. 形式同现在分词,有四种。

一般主动式doing, 一般被动式being done

完成主动式having done,完成被动式having been done

2. 动名词的基本用法:

1) 作主语:Seeing is believing. / Talking is easier than doing.

2) 作表语:My hobby is collecting stamps . /His job is washing and cooking.

3) 作宾语:When he came in, we all stopped talking . /He has given up smoking.

4) 作定语:This is her father’s walking stick.

3. 动名词的复合结构:

形式:his/him working there, Wang Dong’s/ Wang Dong working there

语法功能如下:

1) 作主语:Your smoking too much will do harm to your health.(动名词的复合结构在句首作主语时,只能用sb’s的形式,此句中的Your不可改为You。)

2) 作宾语:I don’t like his/him staying with us.

3) 作表语:My joy is his winning the table-tennis game.(his不能改为him)

4. 动名词的完成式:

动名词的一般式所表示的动作为一种时间要领不强的或泛指的动作,或是与句中谓语同时发生。或在谓语之后发生的动作。

如果动名词的动作发生在谓语动作之前,则要用完成式。例如:

We were praised for having completed our task ahead of time.

在remember, forget, regret, excuse, apologize等动词之后,某些介词后,或某些习惯用语中,用动名词的一般式就可以表示完成式的概念。例如:

I remember him some money before.

He forgot me that. /After finishing his homework, he

went out for a walk.

5. 动名词的被动式

如果动名词的逻辑主语为动名词所表示动作的承受者,这个动名词就要用被动式。

例如:The problem is far from being settled.

动名词的完成被动式往往用一般被动式来代替,以免句子显得累赘。例如:

I still remember being invited(代替having been invited)by a famous artist when I was in Shanghai.

6. 动名词与不定式作主语、宾语的用法比较

<1>作主语:

(1)多数情况两者可以互换。例如:Seeing is believing.=To see is to believe.

Talking is easy and doing is difficult.=To talk is easy and to do is difficult.

(2)如果表示一种具体、短期的行为,或表示将来的行为,宜用不定式。例如:

It took him two hours to finish the work.

To be a scientist is his desire(愿望).

(3)如果表示一种经常性、习惯性的行为,一般用动名词。例如:

Getting up early is a good habit.

<2>作宾语:

(1) 有些动词跟不定式、动名词作宾语皆可,意义也差不多,主要有:begin, start,

continue, love, prefer等。

(2) 有些动词后只跟不定式作宾语,主要有:wish, hope, expect, demand, refuse,

decide.

(3) 有些动词后只能跟动名词作宾语,已学过的这类词有:finish, imagine, insist on, enjoy , escape, consider, can’t help, admit, avoid, mind, miss, practice , put off(延迟)=delay, suggest, feel like, look forward to, devote…to(doing),be worth.

(4)有些动词后跟不定式、动名词意义有明显差别,主要有:forget, remember, regret, stop, mean, try, want, need, require, go on
