who did Mary buy gifts for为什么用who？

Who did Sarah buy gifts for?为什么要用助动词。~

要是不用助动词，变成who Sarah buy gifts for，who和sarah就连起来了，难以辨别意思，助动词是为了组成句子结构，更清晰、容易理解。

应该填for吧！buy……for…… 为谁谁谁买什么？Sarah给谁买礼物那？

1. 首先，可以理解为这是一个完整的句子，那么在这个句子中是用Who来进行提问的，此类句型为特殊疑问句。

2. 从语义理解上来说，who是用来作为介词for的宾语，因此有朋友才会说可以用whom；但就我个人的理解是这样，一般在复合句型中才会这样用，例如，Do you know whom Mary bought gifts for?
   

这句话也可以用Whom
玛丽给谁买的礼物？

题目是这么写的吗？who did Mary do
玛丽为谁买的礼物

员成盐酸： 变成特殊疑问句应该用特殊疑问词引导吧 所以 我觉得应该是 对不同的对象有不同的问法 比如说 对mary : who bought some apples yesterday? 这里应该不用变 对 动作 :what did mary do yesterday?此处觉得应该为它的特殊疑问句 对事物:what did mary buy yesterday? 对时间:when did mary buy any apples?这个地方要变成any 差不多就这么些

聊城市19126413961： who 过去时特殊疑问句 后面加助动词did么？
员成盐酸： 你可能将带有特殊疑问词who的疑问句与一般疑问句混淆了. who开头的特殊疑问句的构成: who+陈述句语序,不用加助动词.(因为who就是主语): Who bought it? what开头的疑问句,因为将宾语what提到句首了,所以主语前加助动词did: What did you buy? 你举的例子who did buy the bag?是错的,正确的句子应是: who bought the bag?
