句子的结构是“Why didn't you tell me you could lend me the money I ______ it from the bank.”，其中“Why didn't you tell me”是一个疑问句，表示“你为什么不告诉我”，后面的部分是“you could lend me the money I ______ it from the bank”，表示“你可以借给我钱，我______从银行借”。

步骤 2：分析句子时态
根据句子的时态，可以判断出“you could lend me the money”是过去时态，表示“你可以借给我钱”，而“it from the bank”是过去时态，表示“从银行借”。

步骤 3：选择合适的选项
根据句子的时态和语境，可以判断出“needn't have borrowed”是正确的选项，表示“本不必从银行借”，因为“you could lend me the money”表示“你可以借给我钱”，所以“needn't have borrowed”表示“本不必从银行借”。
