    以下問題,其實是視狀況而定

    我在書裡看到

    Cliffs undermined by the sea 被海水侵蝕的峭壁

    這不是句子,只是一個名詞(後面由一個做受詞的關代所連接的形容詞子句所

    修飾著)

    Cliffs undermined by the sea. = Cliffs (which are/were) determined by

    the sea.

    這種名詞常見於標題!如下: http://www.cnn.com/2011/WORLD/africa/05/09/ivory.c...

    1.被動為什沒有+be動詞??

    是被動沒錯,原因如上!

    我在字典看到

    The waves had undermined the cliff.

    這句是主動態

    波浪沖刷侵蝕懸崖的底部。

    2.為什有had 呢??

    3.為什用had不用has?

    這也是視情況而定!基本上,過去完成是不能單獨存在,須和過去式連用!

    The waves had determined the cliff.應該只是一篇文章中的一句而已!(一定還有其他的上下文才是,或是大家以知該時間發生背景為過去時間!)

    e.g. Before Jack went to school, he had had lucnh already.

    e.g. Before Jack went to school, he had had lunch already.
