It's missing.=It was lost.=It has gone.

it has gone与it was gone it was gone和it has gone区别? Maybe it has gone! it's gone,这里的it‘s是it has 还是it is? 英语翻译选合适的词1.She has _____(left,lost)her book.It's called Gone 句子-英译汉once it's gone,it never come back as it was used to be she's got it= she has got it对吗 it’s gone为什么不用it have gone "It is said that he has gone to Australia"里的it's said是什么意思 It'sa small blue case andit's got a zip.(It's=It has) It has gone far too far. 请问It was 和 It has 可以缩写成It's吗?
