105.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.
(c)infrared radiation, however, is invisible because its wavelength--0.1 millimeters--is too long for the eye to register it.
OG解释说（c）的it指代不清，为什么呢？我觉得挺明显的啊，这个是哪种错误呢？
106.As well as heat and light, the sun is the source of a continuous stream of atomic particles known as the solar wind.
(B) Besides heat and light, also the sun is the source of a continuous streaming.
（D）The sun is the source not only of heat and light, but also of a continuous stream.（正确）
OG解释Besides会confusing， 为什么呢？觉得除了stream（ing）不能排除（B）啊。。
109.The nephew of Pliny the Elder wrote the only eyewitness account of the great eruption of Vesuvius in two letters to the historian Tacitus.
OG say A" the sentence suggests that the eruption of Vesuvius took place in the letters themselves"
E） In two letters to the historian Tacitus,the nephew of Pliny the Elder wrote the only eyewitness account of the great eruption of Vesuvius.(正确)
OG对A的解释是什么意思呢？这个歧义到底是什么呢？不理解啊 |
