C. twice as many D. twice more than
【解析】选C.考查倍数表达法.句意：使他感到惊讶的是,他只邀请了二十个朋友吃晚餐,但来了两倍的人.此句为：倍数+as + adj. （+as. . . ）结构.
为什么as可以省略?不是说前面有一个as后面就必须有一个as与其对应吗?另外,请详细解释A.
答
as twice as many在这里的意思是与两倍一样多的,而解析中讲的倍数表达法应该是 A is 倍数+as+adj.+as B,这用于讲A的（大,小………）是B的多少倍.例如：A is twice as big as B,即 A是B的两倍大.所以A选项是错的,要选C
