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

answer (A), but a bit confused:
如果把（C）中最后的it 去掉(...too long for the eye to register), C选项是正确的吗？

many thanks.

这个题目我觉得还是选A,首先too...to...结构是一个整体中间最好不要加其他的成分.如果吧for the eye 放在register后面就不好说了

C 中的 its wavelength 和 to register it 又混淆。
its wavelength 中的 it 指的是 infrared radiation， 而 to register it 中的 it 指的是 its wavelength, 不一致。
请参考：

83. Any medical test will sometimes fail to detect
a condition when it is present and indicate that there is one when it is not.

A. a condition when it is present and indicate that there is one
B. when a condition is present and indicate that there is one
C. a condition when it is present and indicate that it is present
D. when a condition is present and indicate its presence
E. the presence of a condition when it is there and indicate its presence

D 中的 indicate its presence when it is not. 有类似的错误。

我也像知道, 请高人指点

吾非高人, but allow me to express my view: (A) is still better (more logical) than the corrected(C). Normally, "too hard for somebody to do something" has an active sense. However, the eye is not a proactive agent in this context as it receives the wavelength of IR. That's it, the passive sense is more fitting. 请批评指正...

同意,c选项有eye主动register的意思

晓路

的确c选项有eye主动register的意思

不过这道题怎么都感觉有点别扭，眼睛register波长而不是波本身？

og234The 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 top 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

og解释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.

我的问题：为什么d中的it是inprecise的，按照逻辑指代原则，it指代the wavelength of infrared

radiation，那么黄色部份是正确的，当然绿色的在这种情况下错误；反过来，按照ets解释，绿色

不正确原因成立，那么黄色部份的it指代就是清晰的，指代the wavelength。也就是说，按照我对

ets自己的解释的理解，不应该同时出现代词指代和句子谓语修饰的错误，好比“矛和盾”。反

之，est两者都解释正确，那我的理解错误。

不知道我说清楚了没，自己也觉得很搞不清楚，见谅。附上自己的理解，请指教。

我的解释：代词指代不清，指代分句主语还是分句主语的修饰部份，错，当所有各为主语时，其

后的代词指代可能产生指代不清得问题；谓语动词修饰错误，原句意思infrared radiation is

invisible，这里变成the wavelength of infrared radiation is thus invisible,

请求指点，谢谢大家。

附：1、本题中it不应该前句主语，依据见og232

232. Unlike auto insurance, the frequency of claims does not affect the premiums for personal property coverage, but if the insurance company is able to prove excessive loss due to owner negligence, it may decline to renew the policy.

2、it可以指代所有格整个部份，包括名词及其修饰部份，依据见og231b解释

231. Ms. Chambers is among the forecasters who predict that the rate of addition to arable lands will drop while those of loss rise.

(A)  those of loss rise

(B)  it rises for loss

In B, it refers to the rate of addition; consequently, B makes the nonsensical statement that the rate of addition... rises for loss
