留美老师带你每日说英文 第275期:食品冷藏的秘密

 　　台湾籍旅美老师今天交给我们的句子是：

　　The important part is that most chemical and biological processes run slower at lower temperatures, which means that if you cool food a lot, enzymes¹ and bacteria and fungi² in the food get too cold to decompose³ it.

　　重要的是，多数生物反应与化学变化在低温下进行得较缓慢。也就是，冷藏食物就能使酵素、细菌、真菌更难将食物分解。

1 enzymes

参考例句：

• It was said that washing powders containing enzymes remove stains more efficiently. 据说加酶洗衣粉除污更有效。
• Among the enzymes which are particularly effective are pepsin, papain. 在酶当中特别有效的是胃朊酶、木瓜酶。

2 fungi   

n.真菌，霉菌

参考例句：

• The lawn was covered with fungi.草地上到处都是蘑菇。

3 decompose
