问题     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] 【C5】
选项 A、put through
B、put before
C、put together
D、put forward
答案 D
解析 短语辨析题。句意为：关于动物是怎样沟通才能做到这一点的，已有众多理论提出。依据句中搭配关系，theories为空格所填短语的逻辑宾语，而且该短语应为及物动词短语。put forward“提出”为及物短语，且意义符合上下文和搭配关系，故为答案。put through意为“接通电话”，put before意为“把某事看得更为重要”，put together意为“放在一起”，均不符合文意。
