可唔可以幫下手翻譯(ＵＲＧＥＮＴ）

正確:
I have just faxed (the document) to you. Please check whether or not it has been received.

OR

I have just faxed the document to you. Please check whether or not you have received it .


而「just now,I fax po to you.Please check receive or not.」有問題

1) just now = 啱啱先至 (比人錯覺啱啱先至記起)
同埋，時間通常喺句子嘅尾

2) fax 應該用過去式 「faxed」

3) po 吾知係乜?!?

4) to you. 無問題

5) Please check 無問題

6) 問人「乜乜未」，加 whether or not 喺 verb 嘅前面會順好多同啱 grammar。


Some extra points:
1) it has been received 即「被收到」

詳程請參考「被動式句子 (be + past participle) 」的用法 :
*被動語態*

2) Whether or not 例子:

whether or not you have decided?
你决定好未呀?

PS 其實好多時，OR NOT 可省略

3) 淨係 whehter (同 OR 一齊用)

I do not mind WHETHER you want to go to Japan OR Korea.
你想去 Japan 定係 Korea ，我都唔介意。


多聽、多講、多讀、多寫，俾心機學英文!

Just now, I fax po to you.
由於你傳真之後才寫電郵，所以寫電郵時傳真的動作已是過去，要用past或present perfect tense。此外，po（相信你是指purchase order）要加上個article才可以。若是你跟收件者已經有過聯略，那麼可以用the為個article。不然的話，你就該用a。

Please check receive or not.
To receive是個transitive verb，所以在其後一定要有個direct object。

第一句可以寫為：
I just faxed you a PO. 這個寫法最簡潔。To fax [indirect object] [direct object]相等於To fax [direct object] to [indirect object]。這個句法也可以在to give、to send、和to write等動詞。Just在句中已含有just now的意思，可以省略個now字。

第二句可以寫為：
Please check whether you have received it. 或 Please confirm your receipt of it. 或 Please confirm that you have received it.
通常whether都會跟or not一同使用，但在這個時候，你的目的是想他人去查查收不收到，而收到的機會較大，所以可以省略個or not的部份。其他的兩句是用確認（to confirm）為動詞。那樣，別人在收到後可以以電郵回覆，那麼你便可以知道收件者真的是收到了。

至於補充的問題，第一句的句式正確，第二句漏了一個it字。 兩句的主語有不同，一個是she，而另一個是you。

I have just faxed po to you, please check it if receive or not, thanks.

1. Please note that the (name of document) has just been faxed to you. Kindly check and advice if you do not receive.

2. You can say : I just faxed you the PO, please check and advice.

1) Please phone me on receipt of the fax.

2) 唔係咁有禮貌.

I just faxed something to you. Please check whether you have received or not.

just now... or not. - this sentence is not that popular and is not polite at all.

I just fax the document to you. Please check! Thank You!

just now,I fax po to you.Please check receive or not. 不通順, 也不是太禮貌
