【明報專訊】問：Have not received 和 have yet received 是同一個意思嗎？它們的用法有何不同？
答：Have received 是現在完成式，意思是收到；加上not，變成否定句，意思是沒有收到。而have yet received 應該是手民之誤，正確說法是 have not yet received。
Yet是一個副詞，意義變化頗多，很多時候用在否定句，帶有尚未之意。因此，Have not yet received是尚未收到，它跟have not received 的不同，在於加強語氣。
‧I have not received any news. It is still early.
‧I have not yet received any news. I wonder why.
