现在完成进行时She has been helping me in the past days.用过去式过去完成进行时She had been helping me in the past days.

现在完成进行时She has been helping me in the past days.用过去式过去完成进行时She had been helping me in the past days. he has been awake请问awake是个什么词,这句是现在进行完成时吗? since 时间的时态,什么时候用现在完成时,什么时候用现在完成进行时she_______in the elementary school since she graduated from college in 1990.a/ taught b/ has been teaching c/ was teaching d/ has taught 英语中现在完成被动时和现在完成进行时结构是不是都是have/has been,只不过现在完成进行时后面加现在分词,现在完成被动时后面加过去分词? 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,则为例：Lana has been a nurse since 2009. be occupied with 、、嗯、现在完成时当然是说“have/has been occupied with”,那个、这里的“have/has”是不是表是完成呐、那个“been”又是什么意义啊?还有、现在完成进行时“have/has been doing”、那 怎么想他一样使用完成时和完成进行时?I've lived here for 10 years and she has been living hereI've lived here for 10 years and she has been living here for 12 years. 英语中has been silent里为什么会有been?现在完成进行时和将来完成进行时的公式里都有been,可是它的后面接的都是现在分词啊,谁能解释一下 He has been collecting some sand from many places.是什么时态?是现在完成进行时吗? that has been missing from your hand has been missng 是现在完成进行时吗?还是被动语态?怎么翻呢?that has been missing from your hand has been missng 是现在完成进行时吗?还是被动语态?怎么翻呢? 现在完成进行时的谓语动词构成 I/ we/ you/ they have been doing sth.he/ she/ it has been doing sth.（一）表示从过去某时开始一直持续到现在的动作,并且还将持续下去.The Chinese have been making paper for two thou 新概念中有一句macaroni has been grown in this area for over six hundred years请问has been grown 是什么时态,假如是现在完成进行时的话不应该是has been growing? 为什么现在完成进行时是have/has+been+动词进行时态 但是在“I have been为什么现在完成进行时是have/has+been+动词进行时态 但是在“I have been married for two years ”这句话里marry没加ing 现在完成进行时不是由“助动词have(has) + been+动词的现在分词”构成的吗 那having done是什么啊 关于has been用法has been 是表示现在完成进行时,一般是have/has been+动词-ing.The door has been locked.这是格式怎么理解,我的意思是has been 后面应该是加动词+ing,为什么是加ed形式，就是这点不解。 有关英语的问题He has been working all day.他整天都在工作.这个现在完成进行时的句子能变成否定形式吗? have done 现在完成时 和 过去时有什麼区别啊 顺便说下have/has been doing 现在完成进行时语言简短易懂的最好了~ 谢谢、 how long has your father ( )? --since last year A.left B.been leavingb，不能理解为现在完成进行时嘛？
