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 (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 答案是A 没有问题 1,OG11的解释说Ethat suggests that not all wavelenghs of 0.1 millineters are too long for the eye to register.感觉that好像在修饰 wavelength of 0.1 millimeters ,而不是就近修饰millimeters.难道在A of B that中 that可以指代A of B? E中说it指代不清,是因为前边有2个单数名词不知道指代那个吗?可是B中也没说it指代不清阿 2,C中的itOG的解释说 lack a clear referent.可是按照代词在一个句子中指代一致的原则,it 应该跟its指代是一样的都是infrared radiation,感觉好像没有问题啊?  |
