以下哪句句子寫法正確？

本人認為所有這三句英文都可以適用,不過是從繁複的結構變為簡單結構的句子。因為第一句的To 可以被省略變化為第二句;而did也可以同樣被省略變為第三句,不過若要保留過去式,可以將dare改為dared。

The answer is yes to your last question.

1 和 3 相信無爭議

1 I did not dare to say anything. 普通動詞用法
3 I dare not say anything. 助動詞用法，同意某回答者說dare應改為過去式dared


2 I did not dare say anything. 用了did not即意味dare作普通動詞，普通動詞是否一定用要和to 連用？

" I did not dare to say anything." Is correct.

' Dare ' is a trasitive verb (vt.)
so it must be followed by a preposition.

Also, ' Dare ' is also a auxiliary verb ( v. aux. )
so its form is just like "be".
e.g. My younger sister dare not go out alone

1同3都系正確的,如果只可以選一個,1比較標準

1 I did not dare to say anything.
2 I did not dare say anything.
3 I dare not say anything.

答案是1

I did not dare to say anything
