If the horse won today，it__________thirty races in five years.
A. would have won
B. won
C. must have won
D. did have won
题目解答
答案
A. would have won
解析
步骤 1：理解句子结构
句子的前半部分 "If the horse won today" 是一个条件句，表示假设。后半部分 "it__________thirty races in five years" 是主句，描述了在假设条件下的结果。
步骤 2：分析时态
由于条件句使用了过去时 "won"，表示一个与现在事实相反的假设，因此主句应该使用过去将来完成时 "would have won"，表示在假设的过去时间点之后完成的动作。
步骤 3：选择正确答案
根据以上分析，正确答案是 A. would have won。
