Question

Some dieters find that after their dieting is over, they eat twice___they did before their diet.
A.more than B.as many as C.much than D.as much as
老师,您好,想问一下为何不能选A,是应该说more than twice?还是本身结构无误只是不符合常理呢?谢谢您!另外,句中的did是不是应该改为do呢?
个人认为,A选项本身除了不符合常理外,也不符合语法规则.应该是more than twice they did,如more than four times the length of .选项中为twice more than,所以A不对～
根据语感,可以选择答案D,根据常理可知A不可选,但是还是希望大侠能够对于A的正确使用方法做出举例说明,不甚感谢!

谢谢各位的帮助,说得很详细!还想问一下,我们有A is twice the size of B. 由此,应该可以说A is more than twice the size of B,这里more than 修饰twice,那么如果一定要对A选项作出修改,只从语法的角度出发,是否可以改为 they eat ______more than ____twice they did before their diet呢?

Answer 1

答案是D,“饭量是以前的两倍”.A是指“三倍”,不合常理.
A选项本身除了不符合常理外,但符合语法规则.次数 加比较级 加than 比.多几倍
与 more than twice 的意思 是不一样的
句中的 did不应该改为do
