Alice has gone to England for a__________English course.A.six month B.six mo选什么,涉及什么语法, he has just bought an Australian car and has gone to Alice Springs.句中and后仍然需要用has gone吗主语反正都是他,and 的后项不能不用has吗?he has just bought an Australian car and gone to Alice Springs has been to 和has gone to Everything has gone to Everything has gone to hurt 英语翻译用 has gone to Everything has gone to hurt He has gone to Shenzhen. He has just bought an Australian car and has gone to Alice Springs.为什么这里用an不用a?He has just bought an Australian car and has gone to Alice Springs.请问an不都是用在元音之前吗,这里的Australian car 都不是原因啊,为什 He has just bought an Australian car and has gone to Alice Springs,为什么用两个has,为什么不把第一个has 改成had,因为买车这个动作在go 明明是过去的过去 has gone to和had gone to 的区别 He has never_______Beijingbeen to/gone to/been/gone She_______ shopping A.has been to B.has gone C.has gone to D.has been has gone 和has gone toWhere she has ( ) is a mystery.a.gone b.gone to怎么选?为什么?

Alice has been to East Point(East Point划线提问） （ ）has Alice( ) He (has gone to) Shanghai on business(has gone to)可以换成has been in吗 i hear jannie has gone to hawaii He has gone to Beijing.否定
