i will certainly be pleased if he_______us what he knows about the matter. A dares tell B dare tell C dare to tell D will dare to tell 我觉得A也符合语法规则,为什么不用A啊 dare to do 的to是可以省略的,所以我不知道A错哪了
选择B.B项中,dare作情态动词使用,后面直接接动词原形. 如果是选择A,dare这里加了s,表示在这里是把dare看做是实义动词,dare作实义动词时,后面接动词不定式,那应该是dares to tell. C项,应是dare tell或者 dares to tell. D项中,这里是if引导条件者状语从句,后面用一般现在时表将来,所以不对.
