Grammar
02
Looking at the sentences from the reading passage and answer the questions.
What was spoken in sentence (a) What was finished in sentence (b)
Why does the author use -ed instead of -ing
Because “the words” were “spoken” instead of “speaking”, and “the well” was “finished” instead of “finishing”. The words in bold show passive instead of active actions.
“The words” were spoken in sentence (a).
“The well” was finished in sentence (b).
Looking at the sentences from the reading passage and answer the questions.
What is the difference between the two groups of sentences
Why does the author choose to use -ed instead of an attributive clause in the reading passage
The sentences using -ed as attributive are moreconcise and formal.
Sentences (a) and (b) contain -ed as attributive while sentences (c) and (d) contain attributive clauses.
-ed as attributive
attributive clauses
-ed as attributive—过去分词作定语
用法：
1. 过去分词作定语的位置
2. 过去分词作定语的意义

过去分词与现在分词做定语的区别
一、 过去分词作定语时的位置
1. 一般情况下，单个的过去分词作前置定语，即放在所修饰词之前。
The recovered animals will be released soon.
痊愈的动物很快会被放走。
有些过去分词表示特定含义时，单独作定语要放在所修饰的名词之后，如left（剩余的）。
There were a couple of seats left at the back. 后面还剩几个位子。
如果被修饰的词是指示代词 those 或 something，everything，anything，nothing， nobody等不定代词时，单个的过去分词作定语要放在这些词的后面。
He is one of those invited. 他是那些被邀请的人之一。
用法
一、过去分词作定语时的位置
2. 过去分词短语作定语时往往作后置定语，即放在所修饰词之后。
These trucks carry goods imported from foreign countries.
这些卡车运送从国外进口的货物。
Is this the novel written by Henry James
这是亨利·詹姆斯写的小说吗？
用法
二、过去分词作定语时的意义
1. 及物动词的过去分词作定语时，在语态上表示被动；在时间过去分词作定语时的意义上，常表示动作已经发生或完成。有时只表示被动。
He is a teacher respected by all the students.
他是一位受所有学生尊敬的老师。（只表示被动）
The plan put forward at the meeting will be carried out soon.
会上提出的计划将很快被执行。（表示被动和完成）
用法
二、过去分词作定语时的意义
2. 不及物动词的过去分词作定语时，不表示被动意义，只强调动作完成。
The risen sun is shining brightly in the morning.
早晨，升起的太阳明亮地照耀着。
When I woke up the next morning, I found the ground was covered with fallen leaves.
当我第二天早上醒来时，发现地上全是落叶。
