Long ago people used to_____with hands but now man is used to working with machines,and sometimes a Robot is used to___instead of people.

A.work;work B.work;working C.working;working D.working;work

答案是A,used to do意为“曾经常常做某事”,be used to doing是“习惯于做某事”,be used to do是被动语态,意思是“被用来做。。。。”

C
第一空 be used to "习惯"后接动名词
第二空Robot is used to"机器人被用来做"+do sth.目的状语

应当选A,used to后接动词原型

A
used to do是曾经做某事的意思;
sth. is used to do sth.是某物被用来做某事的意思。

选A, used to do sth 过去常常做某事。
be used to doing sth 习惯做某事
be used to do 被用来做某事。
所以是A 你应该知道意思了吧?

A is the correct answer.I`m sure.
