请问老师这里的advise表示建议,为何不需要虚拟?

advise有不一样的语义。当advise作建议、忠告解时,that从句用虚拟语气(谓语动词用原型或should do)。此时advise为单宾语动词,that从句前不可以加间接宾语。这是中国英语教学中教过的使用方法,一般大伙都知道。

但advise还有一种意义,即表示公告、告知的意思,意义上等于inform。这是正式用词。这种意义的advise后接双宾语,advise sbthat从句。因为语义上that从句是告知的事实,所以that从句没理由用虚拟语气,而是用陈述语气。以下为牛津词典的解释和例句:

[transitive] to officially tell somebodysomething

SYNonYM inform

advise somebody that…

I regret to advise you that the course is nowfull.

所以,不要一见advise,不管语义,觉得其后that从句需要用虚拟语气。就好比suggest可能表示提示、暗示的意思,其后的that从句是用陈述语气的。
