选择题
Not only should you get used ______ under difficult conditions but you also you pay more attention ______ your work well.
A．to work, to do
B．to working, to doing
C．to work, to doing
D．to working, to do
答案
答案：B
因为 get used to与pay attention to 这两个结构中的to均为介词，不是不定式符号，故后接动词时要用动名词，不能动词原形。类似地，以下各结构中的 to 也是介词，不是不定式符号，后接动词时也应用动名词，而不是动词原形
