就像今天很多伟大的发明一样，微波炉也是其它技术的副产品。

Like many of today's great inventions, the microwave oven was a by-product of another technology.

在超级市场你可能会在一个冰柜里发现大量的素食 它们可以用微波炉来烹调.你可能会尝试它们(我喜欢Amy牌的).请小心 就像大部分便利食物 它们比在家烹饪的食物要贵得多 而且大部分不是非常健康.但你在那也可能找到一些相当健康的食物.不论价格如何 一般来说 最好有一些便利食物在冰箱里 以备不时之需.

Beware that, like most convenience foods, these are more expensive than home-cooked stuff, and most likely not as healthy. But you can find some fairly healthy foods there too.
