英文 ”沒有你們的支持, 我沒有今日的成就” 點講?

講沒有，英文除了可以用without之外，外國人還喜歡用but for
還有”沒有你們的支持，我沒有今日的成就”是對已往沒有發生的事的猜想，這種情況要用：would have never + past participle的形式
所以全句，可以說：
I would have never had my today's achievement (but for/without) your support.
希望幫到你！

沒有你們的支持, 我沒有今日的成就 :
I will not have my goal accomplished today if not for your support !

Without your support, I would not have had my achievements today.

沒有你們的支持, 我沒有今日的成就
Without your support, I'll never acheive my goal today.

I will never have the present achievement without the support of yours.
