雀儿小妖

Rhetorical Construction 下面有两句话：
               Correct: Before we left on vacation, we watered the plants, checked to see that the stove was off, and set the burglar alarm.
               Incorrect: Before we left to go on vacation, we watered, checked to be sure that the stove had been turned off ,and set it.

water后面没有加名词， set it 没有指代这个我清楚，但是另外两个哪里错了？？
