Still、already」 和 「yet」 是三個英語中使用頻率很高的副詞。它們都用來描述當下發生的事情，但含義不同。有關用法如下：
Now let me tell you the difference between 'still', 'already' and 'yet'.
They all talk about things around the present. But they don't mean the same.
— We use 「still」 to talk about something that hasn't finished. "Are you still studying? Let's go out."
— We use 「already」 to talk about something that has finished, and maybe we didn't think it would have by now. "She's already finished work, she's gone home!"
— We use 「yet」 in questions and negatives to talk about things that haven't happened, but we think they will. "Haven't you left yet? You'll be late!"
So, just remember:
-Things that are still happening - haven't finished.
-Things that have already happened - have finished.
-And, things that are yet to happen, haven't started.
好，用英漢對照做一下用法總結：
1 We use 「still」 to talk about something that has not finished.
我們用 「still（仍然，還是）」 來談論未完成的事情。
Are you still studying? Let’s go out instead.
2 We use 「already」 to talk about something that has finished, and maybe we didn't think it would have by now.
我們用 「already（已經）」 談論已完成的事，並且有可能是超出預期完成的事情。
She's already finished work, she's gone home!
3 We use 「yet」 to talk about something that hasn't happened, but we think it will.
我們用 「yet（尚未，還沒有）」 談論還沒發生，但預計會發生的事情。
Haven’t you left yet? You』ll be late!
記住：
事情還在進行中、未完成，用 「still」。
事情已經發生、已經完成，用 「already」。
事情還沒發生、未開始，用 「yet」。
