7. Who is the girl _____ wearing a red dress?
  A. whose   B. that   C. whom   D. that’s
为什么这道题选D?

D

疑问词是Who, 时, 不能用关系代词who, 只能用that 指人, 引导定语从句
B 缺乏助动词is



如不明白请追问,要是满意请【采纳】
祝学习进步这里为什么要用到助动词is?感觉语感that比较通顺。that这个关系代词在定语从句做主语, 难道wearing这个单个现在分词能做谓语?! 这是个"非谓语动词"
只有在前面有个be 动词, 这里是单数is,is wearing 一起构成[ 现在进行时 ] 这才是完整的谓语
