题目

Do you regret paying 5,000dollars for the computer?No,I would gladly pay ()for it
twice many,twice as many ,twice as much ,twice so much应该填哪个?求详细的分析,两倍的价钱应该怎么表示,

答案

应该填 twice as much
涉及到money（钱）,不可数,所以先排除 many.
然后as...as...用于比较,见于肯定句中,其中第2个as有时会省略.
而so...as...用于否定结构,即 not so...as...
故选twice as much.
