howlong和howfar區別
how long“多長”,詢問動作在時間上所持續的長度.其答語部分或劃線部分可能是:
1)“for + 時間段”,有時可能沒有介詞for.如:
---How long did he wait for you here?他在這兒等了你多久?
--- For two hours. 兩個小時.
It took him 20 minutes to finish his homework. (對話線部分提問)
→How long did it take him to finish his homework?
2)“since + 具體時間”,“since + 時間段 + ago”或者“since + 從句”.如:
---How long are you feeling like this? 像這樣已經多久了?
---Since last night.從昨晚到現在.
3)表示時間的between…and…,from…to…等介詞短語.如:
They were playing football from 9:00 to 10:00 yesterday. (對話線部分提問)

另外,how long也可以詢問某事物的具體長度.如:
---How long is the desk?這張桌子有多長?
---1.2 meters. 1.2米.
how far“多遠”,詢問路程、距離.如:
