Passage Two
Compared with the robot, the human worker is undoubtedly superior. He is capable of performing a wider variety of work.
Moreover, he is able to adapt his working pattern in order to cope with changing situations which the robot cannot do. On the other hand, the human worker is relatively weak and cannot tolerate work in extreme conditions such as extremely high or low temperatures.
Consequently, we find humans and robots working together in many areas of work. Robots are used to perform dangerous tasks so that their human operators need not risk their lives. To handle harmful radioactive materials, such as uranium (铀), robots in the form of machined arms are used so the human operators can stay from the fatal rays.

[单项选择] Birds that are literally half-asleep -- with one brain hemisphere alert and the other sleeping -- control which side of the brain remains awake, according to a new ’’study of sleeping ducks.
Earlier studies have documented half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere’’s eye stays open and alert. Birds also can sleep with both hemispheres resting at once.
Decades of studies of bird flocks led researchers to predict extra alertness in the more vulnerable, end-of-the row sleepers. Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze direction.
Also, birds dozing (打盹) at the end of the line resorted to single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Rotating 1
