現(xiàn)在完成時(shí) 結(jié)構(gòu)： 助動(dòng)詞 have / has + 動(dòng)詞的過(guò)去分詞 ( past participle )
用法1 指的是動(dòng)作發(fā)生在過(guò)去某一時(shí)刻并已結(jié)束，但該動(dòng)作對(duì)現(xiàn)在產(chǎn)生了影響，與現(xiàn)在情況具有因果關(guān)系。

現(xiàn)在完成時(shí)常見(jiàn)兩種句型：
① 主語(yǔ)＋have / has been＋for 短語(yǔ)/ since 短語(yǔ)
② it is＋一段時(shí)間＋ since 從句
一般過(guò)去時(shí) 表示過(guò)去某個(gè)時(shí)間發(fā)生的事、存在的狀態(tài)或經(jīng)常發(fā)生的動(dòng)作。說(shuō)話的側(cè)重點(diǎn)只在于陳述一件過(guò)去的事情，不強(qiáng)調(diào)對(duì)"現(xiàn)在"產(chǎn)生的影響。
