但是，到底还有多少可以做的事，目前尚不明朗。便宜的粮食，和便宜的石油，恐怕都是很遥远的往事了。
But it's not clear how much can be done. Cheap food, like cheap oil, may be a thing of the past.
即使往事重新浮现，也是不知不觉悄然而至，直到多少年以后我才觉察到发生了什么。
When they resurfaced, it was covertly, and it would be years before I realized what was happening.
就是这样。至少，你也可以停下来想想：当你回忆往事，你能想起多少旅途和度假中带来的美好回忆，又能想起多少次更换新电器和家具带来的美好回忆？
It is, at least, pause for thought-how many vacations and trips can you recall with happy memories, versus how many devices and furniture upgrades?
