新prep1-238 & GWD-4-4

A new hair-growth drug is being sold for three times the price, per milligram, as the drug's maker charges for another product with the same active ingredient.

A. as

B. than

C. that

D. of what

E. at which

我选的A，答案是C

请教大家：不是说as和than在比较的时候可以做代词的么~那as在这里应该也可以吧。。还是说three times..as...这种用法是错误的？

麻烦明白的CDer帮忙解释下~~~

A is 6 times as large as

A is 6 times larger than

A is 6 times +名词（size，length。。。）

在加上more than 表示比较的时候

A is more than 6times as large as

A is more than 6 times larger than

A is more than 6 times +名词。。。

这个句子中，for three times the price, per milligram,that  the drug's maker charges for another product .  

the price 是上面公式中的名词。。  that在这个句子中是限制性定语从句。。做charge for 的宾语。。。

一些鄙见。。希望对你哟帮助呃。。

A is more than 6 times larger than

A is more than 6 times +名词。。。

多谢solic~~！！！

那是不是说as只有在as..as..结构里才能做指示代词，单独一个as就不行？

three times as/ than + XXXX

XXX要和前面的price对应

简化：

A drug is being sold for three times the price
            as the price that the drug's maker charges for XX.

or：

A drug is being sold for three times the price more than the price that the drug's maker charges for XX.

open for discussion

C的话

名词和定语从句引导词之间可以加插入语吗????

E为什么不对呢

maker charges for ... at ... price
