Grammar过去分词作定语和表语 (the Past Participle as the Attribute and the Predicative)
一、教学设计
【教学目的】
1. Students will learn the Past Participle as the Attribute and the Predicative.
2. Students will use the Past Participle as the Attribute and the Predicative correctly and freely.
【教学流程】
Step 1 the Past Participle as the Attribute
1. The ground is covered with fallen leaves.
2. People today tend to choose vegetables grown without chemicals.
3. The money raised at the evening will be sent to the earthquake survivors as soon as possible.
通过对三个例句的观察,我们可以发现过去分词作定语的主要知识点:
(1)单个的过去分词作定语一般置于被修饰的名词之(前 )。
eg. cooked food, boiled water, fried eggs, a forced smile...
过去分词短语作定语则置于被修饰的名词之(后)。
eg. problems left over by history, a woman dressed in green...
(2) 及物动词的过去分词表示(动词的被动式)
eg. vegetables grown without chemicals,a repaired car…
不及物动词的过去分词只表示(动作已经完成)
eg. fallen leaves, faded flowers, the risen sun…
(3) 及物动词的过去分词可以扩展为一个谓语动词是(被动)语态的定语从句。
eg. vegetables grown without chemicals = vegetables which are grown without chemicals
不及物动词的过去分词可以扩展为一个谓语动词是(主动)语态的定语从句。
eg. fallen leaves = leaves that have fallen
Practice:
Complete the table with phrases that have the same meaning.
Past participle as the Attribute(1) Past participle as the Attribute(2)
terrified people people terrified of (cholera)
reserved seats
polluted water
a crowded room
a pleased winner
children astonished at/by...
a vase broken by...
a door closed by...
the audience tired of...
an animal trapped in/by...
Step 2 the Past Participle as the Predicative
1. The young NBA basketball king James is married.
We are excited to hear the good news.
2. The window of my room is broken. 我房间的窗户是坏的。(表主语所处状态)
The window of my room is broken by my naughty cousin.
我房间的窗户是被淘气的表弟打坏的。(表被动)
3. Don’t be so disappointed.(表主语主观上觉得失望的心理感受)
The result of the exam is disappointing.(表主语客观上具有令人失望的性质特征)
通过对这三组例句的观察,我们可以发现过去分词作表语的主要特征:
(1) 过去分词作表语表示主语( ),相当于形容词的作用。如例句1中的married (已婚的),excited(激动的)。此类常见词还有:表状态:addicted, broken, gone, lost, seated, absorbed, dressed, separated, engaged…表主观心理感受:excited, moved, puzzled, disappointed, surprised, frightened…
(2)当过去分词与be连用时,要注意区分是“系表结构”还是“被动语态”。过去分词在“系表结构”中表示状态,在“被动语态”中表示动作。
eg. The lake is surrounded by grass. (状态)
The lake will soon be surrounded by tall trees. (动作)
The window is broken. (状态)
The window was broken by Tom. (动作)
Practice:
Complete the sentences using the past participle as the predicative.
1. He got upset about losing the money.
2. The painter looked so tired after working for a whole day.
3. I was disappointed with the film I saw last night. I had expected it to be better.
4. Everybody was shocked to hear of the death of the famous film star.
5. Everybody is really amazed about the new Olympics stadiums.
6. His wound became infected with a new virus.
过去分词作表语和定语是非谓语动词重要内容之一,也是高考重要考点,学习时应注意下列几点:
一、理清过去分词作表语和定语的最基本特点
过去分词作表语和定语常常表示被动的和完成的动作。
  典型考例:
 1. Don't use words, expressions, or phrases D only to people with specific knowledge.
  A. being known B. having been known C. to be known  D. known
2. The first textbooks D for teaching English as a foreign language came out in the 16th century.
  A. having written B. to be written C. being written D. written
二、掌握过去分词作表语和定语的形式
  get done也可构成被动语态,相当于be done。例如:
  His right hand got burnt in that big fire.他的右手在那场大火中被烧伤。
  She got murdered last year.去年她被谋杀了。
典型考例:
  1. As we joined the big crowd I got from my friends.
  A. separated B. spared C. lost D. missed
  2. Be careful when you cross this very busy street. If not, you may run over by a car.
  A. have B. get C. become D. turn
三、 弄清过去分词作表语和定语的位置
  单个过去分词作定语常放在被修饰的名词前边,过去分词短语作定语应放在被修饰的名词后边。过去分词作表语时,应放在连系动词后面,但有时过去分词和连系动词之间有副词隔开。
  典型考例:
  1. Most of the artists ________ to the party were from South Africa.
  A. invited B. to invite C. being invited D. had been invited
  2. Prices of daily goods ______through a computer can be lower than store prices.
A. are bought B. bought C. been bought D. buying
