have been 有没有回来我知道have been to 是曾去过表示已经回来 have been in 表示 有没有回来

have been 有没有回来我知道have been to 是曾去过表示已经回来 have been in 表示 有没有回来 have been+v.ed是什么时态,我看有说是现在完成时,那么,它和have+v.ed有没有什么区别,哪位知道给说说, you have been missed ,very much 不知道有没有语法错误,请帮忙翻译下...我也知道是这两个其中一个， have done 与have been doing的区别?两者好像都有可以延续到过去的意思?我知道have been doing 肯定有,比如句子i have lived in U.S.for 2 monthsi have been living in U.S.两者好像没有区别啊,出选择题的话应该怎么 请问：有没有must have been? 有没有have doing这个说法?我们都知道现在完成时有have done 和have been done 两种用法,那么请问现在完成进行时中除了有have been doing外有不有have doing? 在现在完成时的时态里,have been不是应该是去了某了已回来的意思吗?When she ha在现在完成时的时态里,have been不是应该是去了某了已回来的意思吗?When she had been looking for half an hour请问在这个句 有没有been done 这个时态?注意,没有have 有没有 have effects on我知道有have an effect on..但有没有have effects on ... 分子生物学HA-myr-是标签吗?希望有知道的帮我分别解释下：HA和myr. I have never been here.I haven't been here.愿意：我没有来过这里.1.I have never been here.2.I haven't heen here.3.I didn't come here.是否三句都正确?我知道第一句和第二句是现在完成时,第三局是一般过去时.它们有 我去过那三次是I have been there three times还是I have been there for three times 有没有for?为什么? The below Credits have been 我问对方财务款有没有付,对方财务的回答是The below Credits have been raised, 关于英语have been 我做过去时转现在进行时的时候抄答案经常看到have been（没有to) 我做5题有4题答案都是have been ,have been 什么词可以用have been转化为现在进行时的?（我这有例子：married,became,me He has been there for six months这里的has been是什么时态为什么不用gone呢,为什么要用been呢,我知道have been to 是表示去过哪里,但是这里没有to must have been和can't have been和现在完成时有没有联系啊 有没有have been doing 这个时态?must have been doing呢? where have you （ I have （ ）to the bank.A,been been B,gone been C.gone gone D.gone been 选哪个 我觉得是不是第一句话的问号后面没有to 是不是这里有什么决定的
