单选题_______ surprised me most

问题补充：

单选题_______surprisedmemostwas________suchalittleboyofsevencouldplaytheviolinsowell.A.That...whatB.What...thatC.That...whichD.What...which

答案：

B解析考查名词性从句。What引导主语从句What surprised me most，并在句中做主语。That引导表语从句that such a little boy of seven could play the violin so well.因为这个表语从句很完整，所以使用that引导，that没有任何意思，只起连接作用。
