So, this woman, who converted from the Church of England to Catholicism when she married my father -- and there's no one more rabid than a Catholic convert -- decided to teach in the rural areas in Nigeria, particularly among Igbo women, the Billings ovulation method, which was the only approved birth control by the Catholic Church.
哎，我妈原本信仰英国国教， 但她嫁给了我爸以后，她就改信仰天主教了—— 没有任何人会比一个天主教的皈依者更急进的了—— 她决定在尼日利亚的农村地区普及知识， 特别是在伊博女人中间， 普及的知识是比林斯排卵法。 天主教只允许用这种方法来控制生育。
