concerning their 后的名词
如题,在这个句子,another group carried out a second test which was designed to occupy their minds for five minutes before making 空格 decision .最后的名词是什么,为什么……谢谢
一楼的太好了,只是如果before 是后面从句的状从,那又该填什么.

Answer 1

填a ,是短语 make a decision ,后面的从句本来是 before another group made a decision ,但是在从句主语和主句主语相同时可以转化成分词短语,即:从句主语和主句主语相同时把从句主语省去,然后把从句动词变成分词.
