1. Interim analysis must be aforethought and consideration should be given to avoid its possible biased impact on the running trial. 期中分析必须事先计划，要尽可能避免期中分析对试验的影响。
2. Men say, practically, Begin where you are and such as you are, without aiming mainly to become of more worth, and with kindness aforethought go about doing good. 人们很实际他说，从你所站着的地方开始，就照原来的样子，不要主要以成为更有价值的人作为目标，而要以好心肠去做好事情。
3. First-degree murder is increasingly coming to cover more than planned and deliberated killings ("premeditated" and "malice aforethought" were older ways of saying the same thing). 一级谋杀越来越超出原有界定的犯罪定义，即有计划和蓄意杀人（过去对这种犯罪的描述是“事先策划的”和“预谋”）。
