[求助]大全433，多谢指教

433 Intended primarily to stimulate family summer travel, the new airfare, which allows both an adult and a child to fly for the price of one ticket, and also shortens the advance-purchase requirement for family travel to a minimum of seven days rather than fourteen.

(A) and also shortens the advance-purchase requirement for family travel to a minimum of seven days rather than

(B) and also lessens the advance-purchase requirement for family travel to a seven-day minimum from

(C) also shortens the advance-purchase requirement for family travel to a minimum of seven days rather than that of

(D) also lessens the advance-purchase requirement for family travel to a seven-day minimum from（E）

(E) also shortens the advance-purchase requirement for family travel to a minimum of seven days rather than

请问一下这道题为什么不选c呢，我觉得c 比e指代清楚，而且更parallel.

请指教

请问这题C中that指代什么

是指代 a minimum 还是a minimum of seven days

如果是指代a minimum 那么C的表达是否会更好呢

谢谢

1. E读起来通顺简洁一些.

2. 从未划线部分的fourteen来看, fourteen后面明显省略了days. 所以我们能够判断出是seven days与fourteen days的rather than平行对称, 因此没有必要补出that of来明确比较的对象.

3. 从语感上来看, 如果补出that of, 那么也应该明确补出days. that of fourteen的意思不如that of fourteen days来得明确.

谢谢rhod,

我查了章振邦P 1516

由定量和不定量词构成的名词经常省略 如此题rather than fourteen .也就是说 基本就是个固定搭配了 eg. than estimated一样

我还是想再次请教如何判断平行的是

a minimum of seven days / a minimum of fourteen days

还是severn days/fourteen days

有什么标准或办法吗

谢谢

这题我是从简洁和省略来判断的. a minimum of seven days / a minimum of fourteen days, 这里a minimum重复了.

不过, 最快的方法就是从习惯用法来判断, 正如章的语法书所言.
