WhichisWRONG？A.LiMinghasjoinedtheYouthLeagueformorethanhalfayear．B.Li

Which is WRONG？A.Li Ming has joined the Youth League for more than half a year．B.Li Ming has been a Youth League member for more than half a year．C.Li Ming has been in the Youth League for more than half a year．D.It is more than half a year since Li Ming joined the Youth League．

A解析分析：join(参加)是短暂性动词，后面不能有for more than half a year．(延伸)B，C，D实际上就是把A句改正的三种方法。B句是用“have been+名词”的方式(因为Li Ming has joined the Youth League．对现在产生的影响就是Li Ming is a Youth League member．因此可以说Li Ming has been a Youth League member for more than half a year．)C句是用“have been+介词短语”的方式(因为Li Ming has joined the Youth League．对现在产生的影响就是Li Ming is in the Youth League．由此可以变成现在完成时。)D句是用句型It is+时间+since从句(句中用一般过去时)还有一种方式是More than half a yearhas passed since Li Ming joined the Youth League．

我也是这个答案
