In 1854 he found that in two particular streets the cholera outbreak was so severe that over 500 people 3 to cholera died in a short time. He did the research and concluded that the water in the streets was to blame. People were 4 not to drink 5 water any more. Finally, cholera was 6 .
【观察思考】
(1) polluted water 过去分词放在名词之前，people exposed to cholera 过去分词短语放在名词之后。
(2) explaining 与 exposed，分别是现在分词与过去分词，一个表示主动，一个表示被动、完成。
(3) become inspired 过去分词作表语，be instructed/defeated 为被动结构。
Step 2: 过去分词作定语
【观察思考】
a lost animal 一只迷路的动物 a used stamp 一枚用过的邮票
an injured finger 一根受伤的手指 a broken coin 一枚破损的硬币
a lighted candle 一支点燃的蜡烛
(l) So many thousands of terrified people died every time there was an outbreak.

spoken English 英语口语 written exercises 书面练习
(2)少数表示位移或状态改变的不及物动词的过去分词只有完成的意义

(2) He became inspired when he thought about helping ordinary people exposed to cholera,
【归纳总结】
过去分词短语用作定语时，一般置于其所修饰的名词之后，表示被动和／或完成意义。其意义相当于一个定语从句，但较从句简洁，多用于书面语中。
Step 3: 过去分词作表语
【观察思考】
The cup is broken。茶杯破了。（茶杯的状态）
He looked worried after reading the letters.看完信后，他显得很忧虑.（他的感觉／感情）
【归纳总结】
过去分词作表语主要表示主语的状态或思想感情等。
【注意】
过去分词作表语与被动语态的区别：
1. 用作表语的过去分词被动意味很弱，主要表示动作的完成和状态，此时相当于一个形容词。
2. 被动语态的过去分词被动意味很强，句子主语为动作的承受者，后面常跟by短语。
例子：
(l) The glass was broken. 表示状态
The glass was broken by Tom. 表示被动
(2) The windows are closed. 表示状态
The windows are closed by Jack. 表示被动
3. 表示“感觉流露”的一些过去分词 (如：interested, surprised, excited, frightened, shocked) 和一些过去分词 (如dressed, drunk, devoted, lost, known) 常用作表语，表示状态。其中有些仅表示状态，没有被动意味。
(1) How did the audience receive the new play?
They got very excited.
(2) How did Bob do in the exams this time?
Well, his father seems pleased with his results.
(3) She was very disappointed to hear the result.
(4) He’s quite experienced in teaching beginners.

(2) fallen leaves/boiled water/developed country
(3) I am interested in the book.
(4) The book is interesting.
