Tony is a quiet boy and he is accustomed ______ at meals, which is always appreciated.

A．not to talk

B．to not talk

C．to not talking

D．not to talking

答案

C

解析

试题分析：固定搭配be/get accustomed to sth/doing sth习惯于某事/做某事；其中的to是介词，后面要接名词或者动名词形式。动名词的否定式是在前面直接加not。句义：Tony是一个安静的男孩，他习惯于吃饭时不说话，这一点总是收到人们的欣赏。故C正确。
