【题目】I’ve already told you that I’m going to buy a new iPad, _____.
A. how much does it cost B. however much it costs
C. no matter how it costs D. however does it cost much
在线课程【答案】B
【解析】试题分析：本句中的however引导的是一个让步状语从句，“特殊疑问词+ever”既可以引导让步状语从句也可以引导名词性从句，however后面要节形容词或者副词。句义：我已经告诉你了，无论花多少钱，我都要买一新的Ipad。故B正确。
