选项 A.Their botanical classification as berries
   B.Although their botanical classification as berries
   C.Because berries being their botanical classification
   D.Classified botanically as berries

答案 D

解析 考查非谓语动词。分析句子可知,所填空后面为一个完整的句子,主语为grapes,谓语为grow、range 和contain,故横线处不构成句子主干,应为非谓语成分。B项意为“尽管它们在植物学上被归为浆果”与后面的句子在意义上并不构成转折关系,故排除。C项意为“因为它们在植物学上被归为浆果”与后面的句子在意义上并不构成因果关系,故排除。D项“在植物学上被归为浆果”符合语法和语义,Classified 的主语应为grapes,grapes 被归类为浆果,用过去分词表被动。故本题选D。句意:家里种的葡萄在植物学上被归为浆果,它们成簇生长,颜色从淡绿色到黑色不等,且含糖量不同。
