见prep状语从句省略结构：

摘自prep08语法笔记：


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
(1)   正确形式: 表示时间/条件/转折/让步的连词(when/while/if/unless/although/eventhough/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/ whenchildren是错的； if + n.也是错的)
(2)   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 insidethe orbit of Jupiter是错的)(OG10-69)
(3)   特殊情况nce可以加介词短语/名词短语; whatever可以加名词短语

省略的原则：
1. Adverb clauses may be reduced only if the subject of both the dependent clause(the adverb clause) and independent clause are the same.
2. If the main verb of the adverb clause is the 'be' verb,omit the subject and the 'be' verb.
3. If the main verb of the adverb clause is not the 'be' verb, then omit the subject and change the verb to gerund form.

但是觉得第三点怪怪的，好像这样省略的话时态就会变了？作者举了个例子：
Although he got away with murder, he is now the most hated person in America.

解：Since the subject of the subordinate clause(Although he got away with murder) and the main clause(he is now the most hated person in America) is same, we can reduce this sentence.

To reduce, apply rule #3 i.e. remove the subject and change the verb 'got' to gerund form 'getting'

Although getting away with murder, he is now the most hated person in America.

请问OG上有这样的用法吗？请NN指点

第三种的写法似乎不支持呢，我找了一个不是最适合的例子：
Despite its covering the entire planet, Earth has a crust that is not seamless or stationary, rather it is fragmented into mobile semirigid plates.
 
(A) Despite its covering the entire planet, Earth has a crust that is not seamless or stationary, rather it is
 
(B) Despite the fact that it covers the entire planet, Earth’s crust is neither seamless nor is it stationary, but is
 
(C) Despite covering the entire planet, Earth’s crust is neither seamless nor is it stationary, but rather
 
(D) Although it covers the entire planet, Earth’s crust is neither seamless nor stationary, but rather
 
(E) Although covering the entire planet, Earth has a crust that is not seamless or stationary, but

正确答案是D，对E的错误解释是：
Although is a conjunction and should be followed by a finite clause with a subject, not by a participle.
