关于dared 是否属于情态动词,不同语法书有不同理解。夸克认为情态动词dare没有曲折词尾变化,所以认为dared是实意动词dare的过去式。dare作为实意动词,可以后接带to的不定式,也可以后接不带to的不定式,夸克把这称为实意动词和情态动词的混合(blend)。例如:They do not dare ask for more. 这个dare是实意动词,但后...

for可以作为并列连词表示原因,连接并列句;也可以作为介词表示原因,介词短语作状语。为什么要把二者对立起来呢?I still deny this practice for their potential damage. 介词短语作原因状语。I still deny this practice, for it may cause damage. for为连词,连接并列句,表示因果关系。

as 和many 无关,只是碰巧挨在一起了。其实就是As you know, 后接主谓结构这样的句子。传统语法把as从句分析为非限制性定语从句,as指代主句内容。many a +单数名词+单数谓语动词,为古体用法,等于 many+复数名词+复数谓语动词。
