Plays ____twice a month in that theater.

题目

Plays ____twice a month in that theater.
这填空填are put on
are put on是被动语态,即动词用“be+过去分词”的结构.
但是哪体现出"过去分词"呀?put on是过去分词吗?

答案

put的过去分词跟原形正好一样!
put -- put -- put
类似的动词还有很多,平时要注意积累,如：
read -- read -- read
cut-- cut --cut
cost-- cost -- cost
hurt -- hurt -- hurt
set -- set -- set
