pass me the ball/ explain me the problem????

看你也知道，有些動詞可以有雙賓語，像我們非常熟悉的give，如：
He gave his wife a gift.（his wife是間接賓語，而a gift是直接賓語）
這樣的句子也可以寫成：He gave a gift to his wife.
而pass也是帶雙賓語的動詞，所以，第一句，與第二句都沒有問題

但explain, suggest, describe就不可以與　間接賓語＋直接賓語這一結構連用，如：
I'd like him to explain his decision to us（卻不可說：to explain us his decision)
Can you suggest a good dentist to me?（卻不可說：Can you suggest me a good dentist?)
所以，第三句是錯的，第四句是對的
至於，那些動詞可以有用：間接賓語＋直接賓語，那就要看字典了
這四句都與倒裝句無關！

希望幫到你！

1. For sentence one is spoken English, it is fully correct.
2, For sentence two is correct but not really. Since, there is no Subject. Which is only contains the verb and object as well.
3. For sentence three is the same issues as sentence one. Please refer it.
4. For sentence four is the same issues as sentence two. Please refer it.
