A study — by allen lucks,director of big brothers big sisters,found volunteerss had better health than nonvolunteers.A was lead B led C leading D was leading 我就是拿不准要不要选was,was在句中不能当谓语吗?为什么不选呢?
A study 是句子的主语,found 是谓语,后面接了一个省略了that 的宾语从句.
所以句子的主干为A study found volunteerss had better health than nonvolunteers.
led by allen lucks是过去分词作定语,修饰study.因为study 和lead 之间是被动的,所以用的是过去分词.如果你选A,那was led应该作谓语,那found 也是谓语,而且2个谓语之间没有and之类的连词,所以你的思路是不正确的
