Like the Egyptian pharaohs, Shih Huangdi started to build his tomb the moment he became king and some 700,000 conscripts worked for 36 years to complete it.

但是题目中改变了写法，稍不一样。

这根题目中还是有些差别的吧，毕竟这个不是sth take sb some time to do的形式

支持7楼的看法！离被修饰成分太远了，有必要明确一下。

tobytao

支持C，不用it。

LDOCE地complete中有这样的例句：

The building took two years to complete.

呵呵，难道GMAT语法与此有出入？

看这道OG:

234. The physical structure of the human eye enables it to sense light of wavelengths up to 0.0005 millimeters; infrared radiation, however, is invisible because its wavelength—0.1 millimeters—is too long to be registered by the eye.

(A) infrared radiation, however, is invisible because its wavelength—0.1 millimeters—is too long to be registered by the eye

(B) however, the wavelength of infrared radiation—0.1 millimeters—is too long to be registered by the eye making it invisible

(C) infrared radiation, however, is invisible because its wavelength—0.1 millimeters—is too long for the eye to register it

(D) however, because the wavelength of infrared radiation is 0.1 millimeters, it is too long for the eye to register and thus invisible

(E) however, infrared radiation has a wavelength of 0.1 millimeters that is too long for the eye to register, thus making it invisible

Choice A, the best answer, is clear, idiomatic, and grammatically correct. In B, the misplaced participial phrase making it invisible modifies eye rather than wavelength, thus producing a confusing statement that distorts the meaning. In C, D, and E the use of the second it is so imprecise as to be confusing. Furthermore, in D, and thus invisible incorrectly modifies wavelength rather than infrared radiation. Choice E produces an illogical statement by using a restrictive clause introduced by that where a comma followed by the nonrestrictive “which” is required: a wavelength of 0.1 millimeters that is too long nonsensically suggests that not all wavelengths of 0.1 millimeters are too long for the eye to register.

it in C is imprecise.

支持原题C正确。

the question is not about "sb. take sometime to do sth.",but "sth take sb. sometime to do".

In the latter,it just like a passive,and the subject is the object of the verb.

So,how can we not to omit "it".

If we do not omit "it",how about sth and "it" to the verb.

应该省略it，took这个动作的发出者就是the army，it took。。。to complete it就说不通了

看一下OG183. 

183. Archaeologists in Ireland believe that a recently discovered chalice, which dates from the eighth century, was probably buried to keep from being stolen by invaders.

(A)  to keep from

(B)  to keep it from

(C)  to avoid

(D)  in order that it would avoid

(E)   in order to keep from

In choice A, the phrase/row being stolen lacks the necessary noun or pronoun that specifies what it is that might be stolen. Choice B is best because it provides the pronoun it, which refers to chalice. Like choice A, choices C and E lack the pronoun. D is wordy and awkward in its use of the passive voice. Moreover, avoid is used imprecisely in C and D because it illogically suggests that the chalice is acting to prevent its own theft.

如果被动不合理，加入代词是GMAT语法认可的做法。而比较好的说法是It took somebody some time to do sth.，所以B也有合理的地方。
