大全 532

532.New theories propose that catastrophic impacts of asteroids and comets may have caused reversals in the Earth’s magnetic field, the onset of ice ages, splitting apart continents 80 million years ago, and great volcanic eruptions.
(A) splitting apart continents
(B) the splitting apart of continents
(C) split apart continents
(D) continents split apart
(E) continents that were split apart

对答案没有疑问，但是为什么这句句子里面几个词组有的前面加the有的没有加呢？不是说平行的结构里要么都有冠词要么都没有嘛？

请NN指点！

OG11-132:

One view of the economy contends that a large drop in oil prices should eventually lead to lowering interest rates, as well as lowering fears about inflation, a rally in stocks and bonds, and a weakening of the dollar.
        

(A) lowering interest rates, as well as lowering fears about inflation,
            

(B) a lowering of interest rates and of fears about inflation,

(C) a lowering of interest rates, along with fears about inflation,
            

(D) interest rates being lowered, along with fears
            about inflation,

(E) interest rates and fears about inflation being
            lowered, with
            

OG的解释：“Parallel noun phrases list two effects, a rally ... and a weakening, so the first effect in the series must be written as a lowering.”

OG上好多这样的例子的，不过我记得大多都是2个或3个的并列，都是要么全加冠词要么全不加。

4个并列的好像就这一题。难道因为并列的太多了就不需要太关心冠词了么～

请NN指教!

我觉得是因为reversal用了复数

我有另外一个类似问题：限定性定语从句的先行词如果是虚词（比如peace）要用定冠词the嘛?我查书的时候发现既有不加，也有加的例子，所以很疑惑，还是说根本就是根据情况来定？

大全532中的定冠词是否使用是要根据意思来判断的,不能一概而论

reversals in the Earth’s magnetic field, great volcanic eruptions都是泛指

the splitting apart of continents 80 million years ago是特指80 million years ago的那次

the onset of...我觉得是习惯用法,表示...的开始

2楼的例子从意思上判断都是泛指,所以都用不定冠词
