继续弱弱的问，PREP语法笔记的题目探讨

P70,

in addition to having more protein than wheat does, the protein in rice is higher quality than that in wheat, with more of the amino acids essential to the human diet.

(A) the protein in rice is higher quality than that in

(B) rice has protein of higher quality than that in

(C) the protein in rice is higher in quality than it is in

(D) rice protein is higher in quality than it is in

(E) rice has a protein higher in quality than

我怎么看，也看不出来A错在哪里，不就是the protein in rice is higher quality than [protein] in wheat么

P72,

The results of the company's cost-cutting measures are evident in its profits, which increased five percent during the first three months of this year after it fell over the last two years.

A. which increased five percent during the first three months of this year after it fell

B. which had increased five percent during the first three months of this year after it had fallen

C. which have increased five percent during the first three months of this year after falling

D. with a five percent increase during the first three months of this year after falling

E. with a five percent increase during the first three months of this year after having fallen

答案C最后的after falling 是状语省略，求教下是怎么省略的？

1\A中in addition to having...成了dangling modifier,变成protein has more protein~
2\after是定语从句中的，所以它的主语是定从的主语profits，所以补全后是after the profits(换成they应该也可以） have  fallen

多谢答复，那是怎么变成falling的，我问这个问题是因为 一般来说when doing分词结构 好像否是错误的吧。。这里的falling是怎么来的呢？困惑~~~

sorry~今天考试所以才看到~ 那么晚回复抱歉哈~~
关于状从的省略问题，PREP上有详细的说明：
1.    状语从句的省略：
1）    两点省略要求：
第一点是毫无疑问的：逻辑主语等于句子主语
第二点也是必须的：从句的谓语必需是be（没要求主句谓语也必需是be！换句话说状从的省略可以看成是省略了一个be），且从句主语和谓语要么同省，要么同留。
2）形式
(5)    正确形式: 表示时间/条件/转折/让步的连词(when/while/if/unless/although/even though/even if) + 形容词短语/-ing短语/-ed短语
(逻辑主语等于句子主语)  (所以when a child/ when children是错的； if + n.也是错的)
(6)    错误形式:表示时间/条件/转折的连词 + 介词短语/名词短语 (although just inside the orbit of Jupiter是错的)(OG10-69)
(7)    特殊情况nce可以加介词短语/名词短语; whatever可以加名词短语

我觉得这个 after ving 还是不要归到状语省略里面吧。

这题OG12-86. DUKB 的千行。


BABY姐和aeo版主关于after doing的看法：

baby：因为有个"after"

I went home after finishing school.
I go home after finishing school.
I will go home after finishing school.

你发现了，甭管主句是什么时态，都是"after finishing school"。这是个规律——通常v-ing在时态上默认跟随主句时态。比如说这三句话，如果"finishing school"这个动作正常写的话，应该分别写成
After I finished school, I went home.

（这个句子也可以写成After I had finished school, I went home. 语法上两者都没问题，只是语言表达的侧重点不同。）

After I finish school, I go home.
After I finish school, I will go home. （这里照理说是"After I will finish school"，但将来时的惯例，大家知道的.....）


AEO斑斑：

时间介词 + doing是例外~
不过和其他介词+doing的简写一样，都是因为人们很好理解它的时态所以简写了。
所以不要记忆“介词+doing所表示的时态和主句一样，时间介词 + doing是例外”这样的死规则，而要去理解“为什么要简写” --> 因为简写了人们依然能“正确”理解主语、时态等等元素。


这题曾经有人在manhattan问过ron，如果after falling变成一个完整的句子应该怎么补充，ron的答案是别试图去fix the sentence 而且他说他找不到很好的方式去补全这个complete sentence..（没有给出理由）

那这里省略的是 after "profits are/were" falling? 这里imply的时态 是哪个？
应该是were吧？

over the last two years 中the last two years是最近的两年，用现在完成时~
