they are going on an extended holiday to australia,going
问题描述：
they are going on an extended holiday to australia,going
答
are going on 是短语动词go on(进行、从事)的现在进行时形式,表示一般将来时.
他们要去澳大利亚度长假了.那如果说，他们正在澳大利亚度假怎么说，。。。还有，they will go on an extended holiday to australia,可以表示将来时吗？？先谢啦1.他们正在澳大利亚度假they are on holiday in australia. They are holidaying/vocationing in australia.2.they will go on an extended holiday to australia这句话中有表示将来的助动词will，就是个一般将来时的句子。祝你学习进步！
