高中英语选择题答案选B

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？

Answer 1

不选was,后面的成分作定语，修饰study.这句话的主语是director。

Answer 2

分析句子结构如下： 主语a study 谓语是 found,后面是一个省略that的宾语从句。此句中已经有谓语，所以前面不能再用 was led。 选B的原因是，led过去分词，做study的后置定语，同时表明被动关系。
