题目内容

12．Do you know that tea by Shengnong many years ago．（　　）

A．

invented

B．

is invented

C．

was invented

分析你知道茶是神农许多年前发明的吗？

解答答案：C．
主语 tea是动词invite的承受者，表达的是 many years ago所发生的事情，所以时态应该用一般过去式的被动语态：was/were+过去分词，tea为不可数名词，所以be动词应该用was，故选C．

点评被动语态由"助动词be+及物动词的过去分词"构成．被动语态的时态变化只改变be的形式，过去分词部分不变．疑问式和否定式的变化也如此．
