选C啊
我妈妈18岁的时候在那个工厂工作
A是过去完成时 表示18岁开始工作到过去某一时间,比如从18到23 之后就不在了
B是现在完成时 表示从18岁开始一直在那工厂工作,现在也在
D是现在时 与18岁不符
本句时间状语是过去具体时间点,不是时间段,所以直接用过去时就好了

C
事情发生在过去,而且对现在吴影响也没有其它更后的时间点。所以选一般过去式at the age of 18可以等于when she was 18。这样的话不可以理解为当她18岁时妈妈已经在工作工作了吗,不是过去的过去的动作吗。为什么不选Aat the age of 18可以等于when she was 18,这里的she应该是my mother,因为整一句的主语就是my mother。...
