1．Tell them about ＿＿ it's important for you to stay out late.横线中应填写how还是why?

回答：应该用why而不应该用how，因为这个句子的从句是表原因的宾语从句。

2．如果填写how.那么这个结构对吗？：tell them about how important it's for you to stay out late.（一定要详细解释一下，不然会不懂的哦！！

回答：虽然用how不影响从句的结构，但会造成语意不通。

用why
how后面跟形容词

why在从句中作原因状语，how在从句中作方式状语，意为怎样，根据句意，应填why

用Why 用how的话应该这样写tell them about how important for you to stay out late.

用why+从句。

用how不对。
如果你是想说：告诉他们你呆在外面很晚很重要。应该是：
Tell them that it's important for you to stay out late .
