she has already aired thd roomhas是have的第三人称现在式,而ai

She has【already】aired the room has aired 和 has done,has eaten 等等一样,是现在过去时态.air the room 的意思是“让房间通风透气”has aired the room 是 air the room 的现在过去式.She has 【already】 aired the room = 她已让房间通风透气了.======以下答案可供参考======供参考答案1:这是现在完成时 现在完成时的结构：have/has +动词的过去分词 因为she是第三人称单数所以用has ，air在这里是动词，所以加ed变成过去分词供参考答案2:SHE HAS ALREADY AIRED THE ROOM. - A POSITIVE statement with ALREADY to show early completion of an activity.This is what we called : PRESENT PERFECT TENSE.The present perfect is formed like this: has/have + past participle (usually a verb ending in d, ed, or n). To show a PAST EVENT that has PRESENT RESULT. An example is I have eaten a cake (so I'm not hungry right now). With Present Perfect ALREADY always goes after has/have + before the main verb - AIRED.PAST TENSE - AIR - AIRED.The present perfect is used when the time is not mentioned + when the time is recent !- REMEBER ALREADY ?you are having the right way to learn english - should go for grammar instead of others.more to go ... don't get yourself confused .. slow and steady ... cheers...
