高二英语语法知识点：过去分词做状语2

　　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
