To take an extreme example, farmlands dominated by a single crop are so unstable that one year of bad weather or the invasion of a single pest can destroy the entire crop.

India's persistent food inflation, to take another example, is made worse by an antiquated system of storage and transport that lets between 25% and 40% of some crops spoil before they reach market.

又比如印度持续的食品价格通胀，因为过时的储运系统变得更糟，有些农作物投入市场之前，会有25 - 40%的损耗。

For example you might remember to take your medication at the same time by always doing it after lunch.

比如我们总是在午餐时间之后去吃药就会在相同的时间想起来去吃药了。
