56. We can tell that the problem of bodychecking in Canada ______.
A. is controlled strictly
B. is taken more seriously now
C. is caused by players’ carelessness
D. is connected with players’ interest
根据关键词“bodychecking in Canada,可定位至原文开头,根据“… has dropped. Hockey Canada has followed … in preventing bodychecking”不难判断,加拿大更对待身体拦截问题的态度更加严格了,确定选项B为正确答案。错误选项A所述的“管控更加严格”,错误选项C 所述的“由运动员的粗心所致”,错误选项D所述的“和运动员的兴趣挂钩”在文章中并无明确印证,属于无中生有的情况。
