All I had to do was achieve the B average next term.

我需要做的就是下学期也能拿到平均成绩B。

Less than one in 20 Japanese deemed to have committed a penal offence go to prison, compared with one in three of those arrested in America, where the average jail term is much longer.

犯了刑事罪的人中只有不到二十分之一的会进监狱，而这个比例在美国则是三分之一，且刑期也比日本长得多。
