✔ 最佳答案
因為他已被狗殺死了是過去了的，所以一定要用 was.若果是進行中的，可以用 is. 例如:
He is bitten by a dog.
am are 則不能用在 he 後面的.

被動式：「be(is/was)+past participle(done/cleaned/seen etc.)」，例如：「This room is cleaned every day.」，「This room was cleaned yesterday.」，當我們想知道是誰做或這個動作的原因是甚麼時才用「by」，例如：「This house was built by my grandfather.」，「Two hundred people are employed by the company.」
