SAT的语法会有after S have/has done的吗?after后可以跟个完成时的句子吗? have/has been done 是现在完成的被动语态现在完成时的句子 have、has+done just alerady yet have done 和 has done 的区别现在完成时的结构主语＋助动词 have has＋been＋done＋过去分词是什么意思? 主语+have(has)+过去分词(done) 和主语+have+动词doing If引导的虚拟语气句子一般将来过去还有主语加would have done/been 现在完成时态1 have/has+done,请注意与一般过去式的区别现在完成进行时的句型是主语+助动词have/has+been+doing,若没有动词,则为现在完成时的结构主语＋助动词 have has＋been＋done＋过去分词是什么意思?关键 shoud have done sth是完成时的结构吗? have something done的句子
