英語語法求助（非謂語）!
在做題時,很多因動賓關係而用過去分詞形式的題我覺得也可以用被動式來做.這時候該怎麼判斷是用被動式還是有過去分詞呢?

解答：

過去分詞與現在分詞、被動式的用法區別
動詞非謂語形式中的分詞是高中英語重點語法項目之一,由於其變化較多,學生多認爲難記,並易混淆,尤其是過去分詞與現在分詞的被動式的用法區別.現就這兩種用法加以比較.
1．作原因狀語時,過去分詞與現在分詞的的被動式being done可以互換.
如： Done in a hurry, her homework was full of mistakes=Being done in a hurry, her homework was full of mistakes. 這時以上兩句意思都差不多等於： As her homework was done in a hurry, it was full of mistakes.
2．作原因狀語時,分詞的動作與謂語的動作同時或基本同時發生時,用being done不用done,
如： Being made fun of, she couldn't help crying.
3．作狀語表行爲方式或伴隨時,常用過去分詞（短語）而不用現在分詞的被動式（being done）.
如： The teacher came into the room, followed by a group of students. The old man stood there, surrounded by some children.
習慣上不用：Being followed by a group of students, the teacher came into the room.
4．作時間狀語時,過去分詞與having been done差別不大,其意義只等於一個時間狀語從句.
如： Discussed many times, the problems were settled at last=Having been discussed many times, the problems were settled at last=After the problems had been discussed many times, they were settled at last. 但是：過去分詞（短語）常用來作定語,而having been done卻不能,只能作狀語.
[誤]The book having been given by her uncle is a present for her birthday.
[正]The book given by her uncle is a present for her uncle.
5．作定語用時,過去分詞表示動作發生的時間早於謂語動詞,或沒有一定的時間性,只表示純粹的被動關係,而being done則表示動作正在發生尚未結束,或差不多同時發生.
如： The thing being discussed here must be kept as a secret.
The things which are being discussed here must be kept secret. 而過去分詞作定語沒有這種時間關係.
如： The recorders made in this city are much cheaper.
