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.
as
than
that
of what
at which
题目分析:
本题从划线部分开始其实是一个定语从句,先行词为the price。很多考生可能会记得一个说法:“逗号后面不能加that”。这是完全错误的,应该记为:“that不能引导非限制性定语从句”。例如本题,per milligram其实是一个插入语,不影响the drug's maker charges for another product with the same active ingredient作the price的限定性定语从句。
选项分析:
A选项:as在本选项中只能做连词(因为前后都是句子),其的含义为“因为、像”等。但是,在语义上,as前后的两句话不具有因果,也不具有比较关系。
B选项:英语语法规定,than必须和more(或其它比较级)一起出现,不能单独出现。
C选项:Correct.本选项在语法和逻辑上均是正确的。
D选项:本选项有一定的迷惑性。介词of身后加了一个由what引导的名词性从句,在意思上看起来似乎也没什么不妥。我们知道,A of B结构,of B可以看成是A的所有格定语。虽然定语从句和所有格都可以被认为成是定语,但是两者有语意上的区别有区别的,例如:teacher who is woman和teacher of woman(或woman’s teacher)。前者是“女教师”的意思,后者则是“女人拥有的老师”。也就是说,定语从句做定语,表示的是其修饰的名词的一个子集;而所有格则表示一种拥有关系。用之于本题,“药物制造商收取的价格”和“价格”之间只能是子集关系,不能是拥有关系(不能翻译成“药物制造商收取的价格所拥有的价格”吧。。。)。应该用定语从句而不是所有格定语。
E选项:连词at which虽然引导的是定语从句,但是先行词price在身后的从句中只能充当状语,这是不正确的。其应该作为charge的宾语。
E price是charge的直接对象(charge a price),所以不需要再加介词,直接that即可;charge at a price是错的,sell sth. at a price倒是可以的。
补充说明
倍数的比较:
(1)x times as much/big as B
(2)x times more/bigger than B
(3) A is x times B 或 x times that numbers of B
charge通常后面跟东西,如:charge ¥3 for the pen,也可以直接用charge for sth表示就某物收费的意思(不说到底收多少),如:
Do you think museums should charge for admission? 你认为博物馆应该收入场费吗?
本题,three times the price that the drug's maker charges for another product,that指代the price,被比较对象还原成“the drug's maker charges (the price) for another product,完美
D: of what即为 of the price that the drug's maker charges 那完整就是the price of the price that drug's maker charges, 所以不对。

A new hair-growth drug is being sold for three times the |price(, per milligram, 插入语)【that the drug's maker charges for another product with the same active ingredient--定语从句修饰price 】|.
一种新的生发药物的售价是【该药物制造商对另一种具有相同活性成分的产品收取的】每毫克价格的三倍。
选项D(×): the price + of what (=the price 冗余)that the drug's maker charges
charge $ for sth.: 比如charge ¥3 for the pen,
charge for sth:就某物收费的意思(不说到底收多少),如:Do you think museums should charge for admission? 你认为博物馆应该收入场费吗?

RON: "what the drug's maker charges" is ... guess what ... a price.
therefore, "three times the price of what the drug's maker charges" would refer to the price of a price. that is illogical.
this construction is thus not only "wordy", but actually nonsensical.
E price是charge的直接对象(charge a price),不能再加介词at,否则这个price出现像是句子的状语;再说charge后面加的是for,不是at
D因为what引导的是名词性从句,不是定语从句,what直接指代一个price了,所以这里就是price of price不对
twice的用法:
twice as many…as; twice as much…as;
twice + n.(可以是代词,比如that); twice + what从句;
不可以用在其它形容词或是副词的翻倍,例如twice as rapidly as是错的。
表达倍数用"… times + more +adj.+than,… time as +adj.+than"都正确
三类表示倍数的形容词为:twofold, threefold, fourfold, tenfold等。以twofold为例,其意思为two times as much or as many of something。该类词为形容词,多用于构成形容词+名词的词组,如:a threefold increase in revenue,少用于比较两个事物之间的倍数关系。
D: of what即为 of the price that the drug's maker charges 那完整就是the price of the price that drug's maker charges, 所以不对。
C. that引导定语从句three times the price that the drug's maker charges for another product,正确
上了插入语的当!
倍数的比较:
(1)x times as much/big as B
(2)x times more/bigger than B
(3) A is x times B 或 x times that numbers of B
that指代the price
要注意Which前面加介词,先行词在定语从句中只能充当状语。要确认语义是否合理。
That引导的定语从句,先行词补充完整从句中所缺失的那个成分,在这里是从句中的宾语maker charges (price)
adv. 如同,像……一样
prep. 作为;以……身份;当作;像,如同;当……时
conj. 因为,由于;在......时,随着;以……的方式,像;正如;虽然,尽管
(1)x times as much/big as B
(2)x times more/bigger than B
(3) A is x times B 或 x times that numbers of B
C. correct;that指代price引导限定性定语从句,这里“, per milligram,”是个插入语,要用that来连接限定性定从;虽然that在定从中做宾语,但是为了更为清晰地表达后面部分的定从地位that还是应该补出,切不可因为that没有省略就判C错
charge 直接跟prince,需要at。可以说sell....at a price.
per milligram其实是一个插入语,不影响the drug's maker charges for another product with the same active ingredient作the price的限定性定语从句。
A选项:as在本选项中只能做连词(因为前后都是句子),其的含义为“因为、像”等。但是,在语义上,as前后的两句话不具有因果,也不具有比较关系。
B选项:英语语法规定,than必须和more(或其它比较级)一起出现,不能单独出现。
D:定语从句做定语,表示的是其修饰的名词的一个子集;而所有格则表示一种拥有关系。
E选项:连词at which虽然引导的是定语从句,但是先行词price在身后的从句中只能充当状语,这是不正确的。其应该作为charge的宾语。
倍数关系:A is twice B, 不用A is twice of B
A is sold for 3 times the price THAT sb charges for B 宾语从句直接解释倍数关系
A is sold for 3 times the price OF WHAT sb charges for B 所有格
charge for = the price of , 倍数as as /than/直接加比较名词/加数量词
倍数的比较:as/as, than或直接+名词,直接+the number of 名词
charge a price for a product
the drug's maker charges the price for another product
