I have had this pen for two months. How long have you _____ this pen. had The play has begun for an hour. has been on for an hour. 結(jié)束性動詞不能和表示一段時間的時間狀語連用 ,但是他可以轉(zhuǎn)換成相應(yīng)的延續(xù)性動詞 . buy– have catch(get) a cold –have a cold borrow—keep Come/go /bee—be put on wear be+名詞 join the army – be a soldier Join the Party –be a Part
