帮我看一下我的英文翻译写的对不对...THANKS

It's helpful to marrying couples.
It's useful to marrying couples.
OR
要结婚的新人 = bride-to-be or groom-to-be

newlywed = 剛結婚的人, 與將要結婚的人是不同的
newlywed 既然已經結婚了, 又怎會 going to marry 呢

Yahoo 翻譯只會將已翻譯的字詞串成一起, 文法下不一定是正確的.

It is helpful to the newly married couples.
It is helpful to those who are going to get married.

你的翻译沒有錯,
我利用yahoo 翻译過~!
