重点是“两周”, “在这两周当中”
which 就是指two weeks
而during which 就是during the two weeks 在这两周当中
而at which一般是表示某个时间点的,而不是某一段时间
这句子中间有个逗号,属于非限制性定语从句,一般会用介词+which这种形式来
如果没有了逗号,可以是they stayed with me for two weeks when they did all the housework
因为when可以相应地变成during which/ in which/ on which/ at which
收起
they stayed with me for two weeks,_they did all the housework A、at,后面的she应改为her when while都行。stay是延续性动词,所以都可以 后面
