英语被动时态It （was been visited） by millions of people.我写was visited ,请问有什么区别吗 it‘s been done这句话是什么时态?我个人觉得不是过去式加被动不是应该 it was been done吗?为什么is 是原级? 被动时态 英语怎么说 it's been是什么时态, 英语 it was...beforeit was 能说 had been么?it was 能说 it had been么？ 英语时态选择she asked the worker how long ____to build the chuech.为什么选it had taken 不选 it was taken不是应该用被动的么? 英语 完成时It has been raining for three hours.为什么要加been?加been不是表被动么? I wonder if it's because I haven't been able to be outdoors for so longI haven't been 是什么时态 现在完成时被动语态吗? it was raining是什么时态 it was busy是什么时态 has been是被动语态吗?被动语态到底是什么?还有,英语时态好复杂,有没有简单的掌握方法? 英语被动语态八种时态 英语所有时态 的被动语态句型 If it was thought carefully,it will have been done better.为什么要用was thought和has been done?不是问为什么要用被动语态 是为什么用was和has been It's been snowing是什么时态 英语中的全部时态完整的（要英语的）,如was.to be ,has/have been done It has been increased by a factor of 4.为什么这句要使用现在完成时的“被动时态”?It has increased by three times as compared with that of 1998.而这句却是现在完成时的主动时态 It is/has been…since… It was/will be…before… 这两个句It is/has been…since…It was/will be…before…这两个句型怎么用?要用什么时态?
