若非

The government will have to grasp the nettle. If they don’t, the traffic congestion is going to get out of control.

政府将不得不对此事采取果断的手段。若非如此，交通堵塞问题将一发不可收拾。

The only honourable way to pass a law exam is to make a few notes on the cuff and take a quick shufti at them during the occasional visit to the bog.

于袖口，若偶然陷入泥，挥袖撇之，若非如此，考成绩无从得也。
