But quickly new understandings arose after series of tests were conducted on how people walk on【R2】______ floors. The tests showed people would place their legs【R3】______to keep balance when the floor is shaking. Pat Dallard even believes pedestrians may unknowingly adjust their【R4】______to match the sway of the bridge. Professor Fujino Yozo’s study found that the vibration of a bridge could be caused by the【R5】______of people walking, running and jumping on it because the lateral rhythm of the sway could make pedestrians adjust their walk and reach the same step until it is impossible to stand【R6】______.

选项

答案further apart

解析 利用细节信息“place their legs”和“keep balance when the floor is shaking”以及顺序性原则定位于原文第四段第三句话“If we walk on a swaying surface we tend to com-pensate and stabilise ourselves by spreading our legs further apart…”。这里的“stabiliseourselves”对应题目中的“keep balance”,“spreading our legs”对应题目中的“placetheir legs”,所以正确答案为further apart。
