Question

she said that she_go to that house alone at night.
A dared not to B dared not C did not dare D dare not to
为什么选B?怎样判断dare是情态动词还是及物动词?

Answer 1

答案错了,应该选C did not dare,
特别注意：其中dare后面的动词不定式标志to省略了.
一、dare作实意动词实有人称和时态、数的变化,
即dares（动词的第三人称形式）、dared（动词的过去式)
dare为实意动词解时用do、does或者did not来否定.
如 He dared to open the dangerous box.
He did not dare （to） open the dangerous box.动词不定式标志to可以省略
二、dare为情态动词时,没有人称、数和时态的的变化,
即：它永远只有一个形式dare,且后面跟动词原形,不跟动词不定式.
he dare open the dangerous box.中dare就是情态动词.
dare为情态动词时的否定为：dare not=daren't
