[求助]OG168 that指代问题

168. Today, because of improvements in agricultural technology, the same amount of acreage produces double the apples that it has in 1910.

(A)  double the apples that it has

(B)  twice as many apples as it did

(C)  as much as twice the apples it has

(D)  two times as many apples as there were

(E)   a doubling of the apples that it did

Choice B, the best answer, correctly uses the adverbial phrase twice as many... to modify the verb produces; properly employs many rather than much to describe a quantity made up of countable units (apples); and appropriately substitutes did for the understood produced to express the logically necessary past tense of produces. Choice A awkwardly substitutes the adjective double for twice; uses that without a clear referent; and misuses has to refer to events occurring in 1910. Choice C employs the incorrect much in a wordy construction and also misuses has. D is wordy and imprecise;... as there were in 1910 refers to all apples produced in 1910, regardless of location. E is illogical: since that refers to a doubling, E nonsensically asserts that the doubling occurred in 1910.

想请问

（Ａ）that 为何指代不清楚, 除apples之外还有什麽可能指代的吗？

    (E) that 为何是指代 doubling ?　不能logically 指 apples吗？

谢谢

如果A中that指代apples，那么it又指代谁呢？it是个单数，所以that it has从句没有合适的指代对象；

E中that定从的指代对象只可能是doubling或apples这两个名词，而it表明指代对象是单数，所以只有doubling。

谢谢stoneren 和 Teky 的解答

我懂了

谢谢～

D is wordy and imprecise;... as there were in 1910 refers to all apples produced in 1910, regardless of location.

斜线部分是说什莫意思啊？是不是说，这样的表达成了说：1910年产的所有的apples，而不是the same amount of acrage 上产的apples了？location是指the same amount of acrage？

Ｔo irenelj78: 你想的挺对的呀．

这道题我有和楼主一样的疑问:uses that without a clear referent?

我认为it 是指代the same amount of acreage, 而that 指代apples, 挺清晰的, 为什么说that without a clear referent? 语法上应该通呀, 不过逻辑似乎不通.

因为答案A似乎在说: 现在生产了双倍的1910年生产的苹果,即一半的苹果同时出现在现在和1910年.

还有一种我能想到的可能的语法指代错误:是不是在正式语体中that 不能指代宾语？

如果把答案Ａ换成double the apples as it did对不对？

请高手指点，　谢谢！！！！！！！！！！！！！！

我不明白stoneren的解释：

A和C中that引导定语从句，并且that在从句中做宾语成份，这和it有什么关系? it 可以指代the same amount of acreage阿！！

请指教！！

OG168的帖子不知为什么只有这一个，可能是大家都懂了，而我有些问题请大家指教：特别是stoneren　XD

OG对选项B的解释：and appropriately substitutes did for the understood produced to express the logically necessary past tense of produces

所以it对应指代the same amount of acreage应该没错

楼主所说第一个问题（Ａ）that 为何指代不清楚, 除apples之外还有什麽可能指代的吗？

试着说一下，that＝double the apples，（其中double是形容词性），也可能that＝ the apples，所以OG说指代不清

第二个问题，我还要请大家帮忙呢，怎么OG会说E is illogical: since that refers to a doubling, E nonsensically asserts that the doubling occurred in 1910.

特别是着色部分，难道E选项中it＝the doubling ?
