can't/couldn't have 過(guò)去分詞和may/might have 過(guò)去分詞的用法怎么區(qū)分啊？can't/couldn't have+過(guò)去分詞和may/might have+過(guò)去分詞的用法我一直都覺得很難懂哦！請(qǐng)知道的朋友給我解釋一下好嗎?謝謝！！

熱心網(wǎng)友

may(might) have + done sth, can (could) have + done sth　表示過(guò)去，推測(cè)過(guò)去時(shí)間里可能發(fā)生的事情。　　Philip may (might) have been hurt seriously in the car accident.　　Philip can (could) have been hurt seriously in the car accident. 菲利浦可能在那場(chǎng)車禍中傷的很嚴(yán)重。把can改為can't表示：推測(cè)過(guò)去時(shí)不可能發(fā)生的事情很長(zhǎng)時(shí)間沒有看英語(yǔ)了，錯(cuò)了8要罵我！
