解析

步骤 1：理解句子结构和时态
对于每个句子，首先需要理解句子的结构和时态。例如，第一句中，"since it rained heavily three days ago" 表明句子需要使用现在完成时，即 "has been flooded"。
步骤 2：确定动词形式
根据句子的结构和时态，确定动词的形式。例如，第二句中，"is made" 表示被动语态，因此需要使用过去分词 "made"。
步骤 3：应用语法规则
根据语法规则，将动词形式填入句子中。例如，第三句中，"will be replaced" 表示将来时的被动语态，因此需要使用 "will be" 加上过去分词 "replaced"。
步骤 4：检查句子
检查每个句子，确保动词形式正确无误。
