过去分词作表语
观察思考：
He was delighted to see the experts.
见到了专家，他很高兴。
He looked tired after the long walk.
走了那么长的路，他看上去很累。
The window remained closed due to the strong wind.
因为大风，窗户仍然关着。
归纳总结：
过去分词除了位于be动词之后，还可以放在remain, seem, get, feel, look, become等连系动词之后作表语，表示主语所处的状态。
即学即练:
1.He lives alone in a cottage deep in the forest, seeming ____ (cut) off from the outside world.
2.The boss felt _____________(disappoint) with the worker owing to the same repeated mistakes.
3.The whole nation was _________(shock) at the death of the scientist.

shocked
过去分词作表语是与被动语态的区别
The cup is broken.
杯子烂了。
The cup was broken by the naugty boy.
那个淘气的男孩把杯子打烂了。
归纳总结：
过去分词作表语时，强调主语所处的状态，而动词的被动语态表示主语是动作的承受者，强调动作。
即学即练：
1.The old man is ____________ (surround)with a group of boys and girls telling an interesing story.
2.The door got ______ (close) by a strong wind.
surrounded
closed
感觉类动词的-ing形式与-ed 形式作表语的区别
1.We were surprised at what he said at the meeting.
我们对他在会上讲的话很惊讶。
2.His look was puzzled because the problem was puzzling.
他脸上露出困惑的表情，因为这个问题很令人困惑。
归纳总结：
过去分词作表语多表示人自身的感受或事物自身的状态，常译作“感到...的”；动词-ing 形式多表示事物具有的特性，常译作“令人... 的”。
英语中有很多与感觉有关的及物动词，其动词-ing形式表示主动意义，即“令人有某种感觉的”，多用来修饰物；其过去分词含有被动意义，即“人被引起某种感觉的”，多用来指人、人的声音或表情等。
即学即练：
1.We were ________(amaze) at the result, because it was too _________(excite).
2.The audience were all ________(move) to tears by the _________(move)film.
3.His voice sounded ___________ (frighten)at the ___________(frighten) sound.

5.The old man sat under the tree, surrouned with a group of children, listening to him tell a story.
老人坐在树下，周围有一群孩子听他讲一个有趣的故事。
归纳总结：
过去分词短语作状语，可以表示时间、原因、条件、让步、伴随、方式和结果等，相当于一个状语从句，或由and连接的并列结构,其逻辑主语为主句的主语，并且与主句主语构成被动关系。
即学即练
1._________(locate)at the centre of the town, the school covers an area of 5,000 square metres.
2.Even_______(invite) by the new couple, he wouldn’t go to the party.
3.The young girl felt very ___________(frighten) at the fierce tiger.

过去分词与现在分词作状语的区别

2.Surrounding himself with a group of sheep eating grass, the young man is lying on the grass listening to a radio.
年轻人正躺在草地上听收音机，周围是正在吃草的羊。
归纳总结：
现在分词作状语时，和句子的主语是主动关系；过去分词作状语时,和句子的主语是被动或动宾关系。
注意：无论是现在分词还是过去分词，其逻辑主语必须和句子的主语一致。 如果不一致，则必须用状语从句、独立主格结构等其他表达形式。

过去分词短语与独立主格结构作状语
观察思考

他擦窗户时把手指弄伤了。
2.The boy knocked over, blood streamed down his head.
那个男孩被撞倒了，鲜血顺着头流了下来。
3.Asked why he was late, the boy kept silent.
被问起为什么迟到时，那个男孩保持沉默
归纳总结：
过去分词短语作状语时，有时在过去分词的前面加上自己的主语，这种带有自身主语的过去分词短语被称为过去分词的独立主格结构。这种结构与过去分词短语作状语的区别在于，过去分词短语作状语时，它的逻辑主语和句子的主语一致，而独立主格结构作状语时，该结构中的过去分词有自己的主语。
即学即练：
