這句英文可否這樣表達~謝謝!

1、We need to inform you that your account is invaild now.
→這句我認為不需加NOW，算是多此一舉。need to 也可用have to，其他的部分是OK的。


2、they have question about schedule but not describe clear
→可改為They have some doubt for the schedule.But the description is not clear.{疑問的英文是doubt，而question是"問題"。 but not 後接名詞description才對。

PS.description是名詞，所以接形容詞(clear)即可。

We feel sorry to inform you that your account is not available at this time.
They doubt about the schedule but can not describe it clearly.---------

need to 是需要，have to是須要，兩者是有分別的。“目前”應該是"at the moment"或"currently"而不是"now"。

>>> 我們必須告知您 你的帳號目前是無效的
一般外國人不會說“我們必須告知你”，而是婉轉點說“很抱歉告知你”之類的。
We're sorry to inform you that your account is currently invalid.

普通疑問用question即可，doubt是指你認為這個schedule有錯誤之處所以感到奇怪有疑問。形容"describe"應用副詞"clearly"，雖然"clear"本身也是副詞但不是用在這種情況下。冠詞要小心，"they have a question"或"they have some questions"，不要只說“they have question"。

>>> 他們對於行程有些疑問 但是描述的不太清楚
They have some problems about the schedule but they haven't made it clear what they(the questions) are.

clear也可直接當副詞
