1.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 答案A 但是我发现A也有问题,不是wavelength 不能be registered by the eye,而应该是infrared radiation不能be registered by the eye。所以没有一个对的! |
