過去分詞作表語與被動語態形式相同,但二者是有明顯區別的.

1.被動語態強調動作,主語是動作承受者.過去分詞作表語說明主語的狀態或特徵.如:

1)This novel was written in 1976.(被動,強調“寫”的運用)

2)This novel is well written.系表,表示特徵)

2.被動語態後常接by+執行者,表示某人做.而過去分詞作表語後不接介詞by,但可以接其它的介詞,表示特徵.

例如:

1)The cup was broken by him.(被動)

2)The cup is broken.(系表)

3)I am interested in English.(系表)

3.被動語態可以有許多的時態變化,而系表結構沒有進行時態.如:

1)Our plan is being carried out successfully

2)Our blan was well carried out.

we are shocked by his apperance 是被動語態

後面你說的太亂了，有點看不懂，你好好看看前面的區別吧
