【高二英语】I must apologize for ____ ahead of time.( ) A.letting you not know B.not letting you...
I must apologize for ____ ahead of time.( )
A.letting you not know B.not letting you know
C.letting you know not D.letting not you know
答
not的位置是放在助动词,情态动词之后,动词,分词之前
而这个句子里,not显然否定的是let you know 这个动词词组,因此放在整个词组之前
