These two days __ us think about the cleaning roles of mother and fathers.

Posted 2023-04-23

A. make B. ask C. take D. require 这题选什么，为什么

从短语的固定用法考虑
make有让某人做，要求的意思make sb do sth
如上述问题

ask sb to do sth
My mom asks Tom to open the door.

take没有要求的意思，排除

require doing sth
The roof requires repairing.
屋顶需要修理了

参考技术A 选A. make
其他三个动词后需要接to do形式，并且语义不对。
