高二英語語法知識點：過去分詞做狀語2

　　現在分詞與過去分詞作狀語

　　現在分詞作狀語時，與其邏輯主語之間是主動關系，;而過去分詞與其邏輯主語之間則表示被動關系。

　　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)

　　選擇現在分詞還是過去分詞，關鍵看主句的主語。如分詞的動作是主句的主語發出，分詞就選用現在分詞，反之就用過去分詞。例如：

　　Used for a long time, the book looks old.

　　由于用了很長時間，這本書看上去很舊。

　　Using the book, I find it useful.

　　在使用的過程中，我發現這本書很有用

　　注意:1.系表示主語所處的狀態

　　_____ 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
