防患于未然

I had investigated that insurance could nip in the bud, but its proceeds is ecumenical, and the fund is not jarless, and the timebargain has much risk.

我调查了一，保险可以防患于，但回报不高，基金不够稳定，期货风险更大。

I do not want drugs in this school. It’s essential that we nip the problem in the bud so I want a meeting with all the parents next week.

我不希望学校毒品。关键于防患于，周我要召开全体家长会。
