现在完成时的两个问题
1.为什么这句话 My brother has never been abroad before.中never是时间状语,而不是before,never难道不是否定词吗
2.my brother never (be) abroad before,空格填什么?
he already has visited a great number of different places.这句话对吗？

efore只是说时间是以前
需要状语修饰,那就是never 总的来说就是：从没有去过外国强调从来
been
不对应该是he has already visited ……

My brother has never been abroad before中为什么要用has never been my brother has never been abroad before 这句话是这个has been to去某 My brother has never been abroad before 新概念英语 My brother has never been abroad before 这里before为什么在后面 my brother has never been abroad before为什么用been而不用gone? 解释句子成分:My brother has never been abroad before." 翻译并现在完成时改成现在进行时my brother never been abroad before . my brother has been abroad before有谁能解释一下为什么是been abroad,abro He has never been abroad before.这句话的主谓宾结构是怎么分的. He has never been abroad before.这里的been是什么 my brother has never been abroad before1那个是表示时间的状语 My mother has never been abroad
