Shoals of fish are able to move and turn in seamless formation by following simple rules that are like those used by car drivers, researchers say.
Some of the most【C1】______sights in nature happen when animals form【C2】______ groups and move together as if【C3】______. Earlier work has shown that fish in large groups make better decisions than【C4】______or small groups.
Many theories have been【C5】______ about how animals might communicate in order to【C6】______this. But now it appears really simple. The researchers【C7】______groups of two, four or eight mosquito fish in a square arena for five minutes【C8】______studied the movements of individuals in each group. The【C9】______of the swimming fish were fed into software which acts like many pairs of eyes to keep【C10】______ on the direction and speed of each fish in the school and【C11】______it responds to other fish around it.
As schools of fish rarely suffer from crashes or【C12】______, the rules they use could also【C13】______be applied to robotic systems to solve traffic problems. If a system could be【C14】______ where each car knew where each car was and they could respond to each other and communicate with each other, traffic problems【C15】______ be avoid.
The researchers used a technique called artificial neural networks to look for【C16】______ in the data. And it turns out the【C17】______ well-organized swimming that fish in shoals【C18】______is actually caused by each fish using very simple rules to respond to its neighbors. These rules include " accelerate towards a neighbor that is far away from you" and " decelerate when a neighbor is【C19】______ in front of you". It is also found that a fish only responds to a single nearest neighbor at any one time. Those【C20】______ to be the rules people use when they are driving. [br] 【C10】
选项
A、eye
B、record
C、track
D、count
答案
C
解析
固定搭配题。句意同上。由上文可知,研究者的目的是研究鱼群中每个个体的移动,再由后文搭配的对象direction和speed,可以判断keep track on“追踪”符合句意。其余各项也均可以与keep搭配构成短语,分别表示“监视”、“记录”和“统计”,但均与原文语境不符,因此排除。
