看一道高中英语选择题
Before leaving home,make sure to turn off the electricity,lock the door,_____the windows open.
A.and not to leave B.instead of leaving C.rather than leave D.and not leave
要解释...

答案：A.
1）从句子的结构看,明显是turn off the electricity,lock the door和选项并列,一起共用不定式：make sure to.
2）但是选项为否定式,而不定式的否定式是在to前面加上not,而不能在to后面加上not,所以排除D,选用A.
