现在分词与过去分词作状语

现在分词作状语时，与其逻辑主语之间是主动关系，;而过去分词与其逻辑主语之间则表示被动关系。

Seeing these pictures, I couldn’t help thinking of those days when I was in Beijing . Seen from the top of a thirty-storeyed building, Beijing looks more magnificent. (see)

选择现在分词还是过去分词，关键看主句的主语。如分词的动作是主句的主语发出，分词就选用现在分词，反之就用过去分词。例如：

Used for a long time, the book looks old.

由于用了很长时间，这本书看上去很旧。

Using the book, I find it useful.

在使用的过程中，我发现这本书很有用

注意:1.系表示主语所处的状态

_____ in thought, he almost ran into the car in front of him. ( lose)

______ in white, she looks more beautiful.( dress)

be lost in

be dressed in

be interested in

be devoted to

be supposed to? be caught in the rain

be seated in

be prepared for

be determined to

2.不与主语保持一致的固定结构

generally speaking　一般说来

strictly/ frankly speaking 严格地说/坦白地说

judging from 从…判断

all things considered 从整体来看

taking all things into consideration　全面看来

例如：Judging from his face, he must be ill.从他的脸色看，他一定是病了。

总的来说，狗比猪跑得快。 (speaking 不是dogs 的动作)
