OG 234

老愚

继续顶，楼上说得不太明白

期待蔚蓝

我觉得amy已经解释的很明白啦！

不过考试时候，不认得红外线怎么办？

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？

我也觉得奇怪，到底是什么 to be registered 呢？

应该是波本身，而不是波长吧？

前面的NN还是没有说通啊：（

难道 too…… to……可以不是一个主语？

OG中，In C, D, and E the use of the second
            it is so imprecise as to be confusing.
我的理解是
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.

两个IT指代不同东西

这题好难呀！

同意39楼的说法。可以排除C。但是对register wavelength or IR还是有疑问。倾向于register IR。

下面是我对这个题的分析和理解：

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 top long to be registered by the eye making it invisible (修饰eye, 而不是修饰radiation)

(C)  infrared radiation, however, is invisible because its wavelength--0.1 millimeters--is too long for the eye to register it (it 直待不清楚，因为从句because的引导，it 直待了because后面出现的主语，wavelength, 因此register it就表明register wavelength, 而不是register radiation.意思错误)

(D)  however, because the wavelength of infrared radiation is 0.1 millimeters, it is too long for the eye to register and thus （省略了it is 这里的it = the wavelength,所以说wavelengh is invisible 也错误） 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 （it直待不清楚，并且that引导的限定定语从句限定了0。1波长的范围，而不是描述他们的共有特性）

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.

我觉得这个题目的答案能够理解，但问题是如果在考场碰到这样的题目，应该如何迅速解题呢？

思考的思路是什么？

两个IT指代不同东西

不同意.OG是说第2个it指代不清.在两个以分号分开的独立句子里,it可以指代不同的事物.
