Question

who helps you是对的吗?这个句子没有助动词
是不是当疑问词作主语时,不用助动词.why can't I help you?这里的语序是对的吧,can't 是助动词应放在实义动词的前面

Answer 1

疑问句有两种语序：
1. 疑问词作主语： 陈述语序——
疑问词(主语) + 动词 + 其他成分,如：
Who helps you.?
What makes you happy today?
2. 疑问词作其他成分：倒装语序——
疑问词 + 助动词（或情态动词）+ 主语 + 谓语动词 + 其他成分,如：
Why can't I help you? (原因状语)
Where are you going? (处所状语)
Who did you meet yesterday? (宾语)
