.Linda was __B__ the experiment a month ago but she changed her mind at the last minute.
A.to start B.to have started C.to be starting D.to have been starting
谁能说的详细些吗
首先be to do sth 表将来
其次,was在这里是个关键词,是个表过去的时态,但不是这个句子中的宾语,在这里的start才是与changed是平行结构,但是两个动词的发生时间是有前后顺序的
先是start 然后才change her mind
但两个都是过去时怎麽体现先后顺序呢?
因此,start 要用过去的过去来表示,即过去完成时.
因此选B.
句子可以理解为：linda一个月前就计划好将要开始做实验,但她刚刚改变了主意.
