文法題目:Did mother give you gift?改成被動語態書上答案是 Were you given the gift by mother? 為什麼不是Was the gift given you by mother?

當一個句子裡面的主要動詞(像是你的問題裡面的動詞give)可以接受2個受詞(直接受詞gift 與 間接受詞you)的時候,這句的被動語態 就會 如你所說的 有2種變法:

原句:
Your mother gave you the gift.
Did your mother give you the gift? (疑問式)

1. 以直接受詞為主的被動:
The gift was given to you by your mother.
Was the gift given to you by your moｍ？(被動疑問式)
The gift was from your mom. (better)
Was this gift from your mom? (better)


2. 以間接受詞為主的被動:
You were given the gift by your mother.
Were you given the gift by your mother？(被動疑問式)
You received the gift from your mom. (better)
Did you ... ? (better)

3. 以上的被動疑問句　雖然都合乎文法　卻都是爛句！
為神？因為它們都不合乎英語的說話習慣．合乎文法是語言裡面並不重要的因素
就像你說中語的時候　會說　＂這禮物被你媽媽給你＂？　你不要笑死人了好嗎？
醒醒吧！學語不要學到死胡同裏面去了吧！

were用在you，而was用在he或she，它( the gift)等第三人稱
再補充一些:
1，若動作發起是事物而非人，用被動式以第二句較妥
2，被動式用在強調事件重要性，一般亦使用第二句
3，本句屬授與動詞，所以二個句子都可使用，就視你強調是人或事物而已

Was the gift given you by mother?錯的
被動式不能把you這個放在後面，應該放前面
given you by mother你不覺得奇怪嗎？

Were you given the gift by mother?
Was the gift given you by mother?
這兩句應都是正確的，
但兩句意思不同，上一句是在說"` 是媽給你這禮物嗎？" 下句意思則"你這禮物是媽給的嗎"
兩句相較被強調的主體不同，上句主體是"你"，下句主體則是"禮物"。
