题目

( )all the window are closed on a windy day or the wind may break the glasses of the windows.A、seeing that B /seen that C see that D seeing it

答案

or 连词,连接两个完整的句子.这里意译为不然,否则.
or前是祈使句：动词（see）+宾语（that all the window are closed on a windy day )
意思是：看!所有在暴风天气中的窗户都被关上了,不然大风会把所有的窗户都弄碎的.
其他选项都是把前面的句子作为从句了.
