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。
划线部分开始其实是一个定语从句,先行词为the price,在从句中作charge的宾语
不是TImes+ as...as 的倍数。。看清楚题。定语从句
考察:
倍数关系的说法
three times the price正常说的话应该是three times the price that sb is charged;因为倍数后直接跟修饰的词,无需加of等各种介词,d错。
这里无非复杂一点加了插入语,从句,但是道理不变,three times the price that。。。,加了插入语,加两个逗号
charge a price
去掉插入语分析
charge xxxmoney
先行词price在后面的从句中充当宾语,用that
his one isn't that bad if you get down to the "skeleton" of the sentence.
a new drug is being sold for three times the price ____ the drug's maker charges.
it's because "price" is the direct object of "charges".
"three times the price of what the drug's maker charges" would refer to the price of a price. that is illogical.
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(另外price出现在at后面常表示代价)
定语区别:
定语从句:从属关系(子集⊆全集)
所有格:拥有关系
three times the price that。。。倍数直接加对象
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。
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。
twice as many...as Right: The man is FIVE TIMES AS OLD AS his grandson.
twice as much...as Wrong: The man is FIVE TIMES OLDER THAN his grandson.
twice + the + n。 Right: The cost of a ticket is $12, SIX TIMES the cost ten years ago.
twice + what从句 Right: The concert was attended by 300 people, TWICE the previous attendance
只有charge the price, 而没有charge at the price.
~ sth (with sth)给某物充电==》引申义:充满着...
charge a battery
a voice charged with tension
charge的用法
~ sb (with sth)以某事控告某人
~ ((at) sb/sth) 进攻
~ (sb/sth) for sth要价
注意灵活的去掉插入语去理解句子的整体含义
收下我的膝盖。。。子集 我都没想到过
