(答案→)A. One good turn deserves another
B. Justice has long arms
C. One false move may lose the game
D. Lies have short legs
解析： 考查交际用语。One good turn deserves another善有善报；Justice has long arms天网恢恢疏而不漏；One false move may lose the game一着不慎，满盘皆输；Lies have short legs谎言总是站不住脚的。句意：如果他帮了你的忙，你也应该帮助他。我非常同意。善有善报。所以选A。
