B. hadn’t hurt；would have taken part in
C. didn’t hurt；would go in for

答案：
(答案→)A. hadn’t hurt；would join in
B. hadn’t hurt；would have taken part in
C. didn’t hurt；would go in for
D. didn’t hurt；would have taken part in
解析：句意：如果他在上一次的训练中没有受伤，他就能参加世界杯，这是他梦寐以求的要参加的。这是虚拟语气，条件状语从句是对过去的虚拟，所以用had done，根据the coming World Cup主句是对将来的虚拟，所以用would do，故选A。
