have been doing 往往怎么用?叫：完成进行时吗? 现在完成进行时的主动和被动语态都是have been doing吗? have been doing和have been done哪个是现在完成进行时啊? have been done 什么东西?have been doing是现在完成进行时的被动语态嘛? 现在完成进行时的被动语态结构是have been +过去分词还是have been+doing 英语的现在进行完成时态是怎么构成的?have being done 还是have been doing? have been doing 该怎么用 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 英语中的“过去将来完成进行时”通常用于什么情况?would/should have been doing结构 将来完成时will have done和将来完成进行时will have been doing,这两个时态有什么区别. have been doing 和 have done 这现在完成时和现在完成进行式在选择题中怎么使用,如果一到选择 完成时的时态小问题Have you been working too hard?这句是完成时吗 还是完成进行时?怎么区别
