2019年mpa考试英语真题——非谓语动词228

{01}— I must apologize for _____ ahead of time.
— That’s all right.
A.letting you not know
B.not letting you know
C.letting you know not
D.letting not you know
解析：试题分析：考查动名词否定形式。Apologize for sth因为sth道歉；for是介词，后面接动名词，动名词的否定形式在前面直接加Not。句意：我必须因为没有提前让你知道向你道歉。故B正确。
考点：考查动名词否定形式
点评：在所有的非谓语动词中，否定式都是在前面加Not，本题主要是句意的理解。
本题选B。
