There __two cups of orange 该填is 还是are

are

are ，这里的宾语是cups ， of orange是介词短语修饰cups

are
there be 句型中遵循"就近原则", 既be动词的形式取决于离它最近的名词.
这道题中two cups离be动词距离最近,应用are. 千万不要受orange的影响咯.

are

there be 句型遵循就近原则。

例： there IS a cup of apple juice and 3 cups of coffee on the table

当然是are，就近原则：two cups与there be 离得最近

are
要根据量词cup，是两杯
