读者 Dean 还问了别的问题，现在继续回答。他问以下哪一句是对的？

1. I would not have failed the exam if I had had three kids to take care of.

2. I would not have failed the exam if I had three kids to take care of.

3. I would have passed the exam if I had not had three kids to take care of.

从文法上来说，第二句是错的。因为以条件式句子（conditional sentence）去表达未能达成的目标时，假设性条件的从属子句应采用过去完成时态而非简单过去时态。所以应改写成 "if I had had three kids to take care of"。

第一和第三句文法完全没有问题。但由于不清楚 Dean 想表达的意思，所以不能判断哪一句是 Dean 需要的。我们试把这两句翻译出来：

1. 如果我要照顾三个孩子，我考试就不会不及格。

3. 如果我不用照顾三个孩子，我考试就会及格。

按照常理，第一句有点不知所云，Dean 所想的应该是第三句。
