5、持續(xù)到現(xiàn)在的動作或狀態(tài)，可以和表示從過去某一時刻延續(xù)到現(xiàn)在（包括“現(xiàn)在”在內(nèi)）的一段時間的狀語連用,如for+時間段、since+過去的時間點、疑問詞how long等。例如： My uncle has worked at this factory for five years. 我叔叔在這個工廠工作已經(jīng)五年了。 Mr. Black has lived in China since 2002. 自從2002年Mr. Black 一直住在中國。 How long have you been here? 你來這里多久了？ 注意：此種用法中表示持續(xù)動作或狀態(tài)的動詞必須是延續(xù)性動詞（否定句除外）。例如
