“Fried rice syndrome” refers to food poisoning from a bacterium called Bacillus cereus(蜡样芽孢杆菌), which becomes a risk when cooked food is left at room temperature for too long. Although death is rare, Bacillus cereus can cause some illnesses if food isn’t stored properly. 16 Here are some suggestions.
17 After cooking a meal, if you’re going to keep some of it to eat over the following days, put the food in the fridge instantly. By doing so you can minimize the time it spends in the danger zone at which bacteria can grow. This danger zone is anything above the temperature of your fridge and below 60 ℃, which is the temperature to which you should reheat your food.
Also, you can divide food into smaller portions. When you put something in the fridge, it takes time for the cold to go into the mass of the food. 18 And this will also minimize the times you’re taking the food out of the fridge.
As a general guide, you can follow the two - hour/four - hour rule. If something has been out of the fridge for up to two hours, it is safe to put it back. If it has been out for longer, consume it and then throw away the leftovers. 19
It’s also important to keep in mind the general principles of food hygiene(卫生). 20 Besides, you’d better use clean dishes and keep cooked food and raw food separate to avoid cross contamination(交叉污染).
A. So smaller portions will help with this.
B. You can recover from them in a few days.
C. Before preparing food, it is crucial to wash your hands.
D. First, you should freeze the leftovers without delay.
E. So it’s still worth doing what you can do to protect against it.
F. Heating leftovers to a high temperature may kill Bacillus cereus.
G. If it has been out for longer than four hours, it starts to become a risk.

答案： 16. E 上一句提到，虽然因蜡样芽孢杆菌引起的食物中毒而导致死亡是罕见的，但如果食物储存不当，蜡样芽孢杆菌会引起一些疾病。下一句提到，这是一些建议。由此可知，E项“所以你还是应该尽你所能来防止它”承上启下，既与上一句构成因果关系，又能引起下文。
17. D 根据下文可知，下文每段的第一句都是段落主题句，空处位于段首，因此所填句为该段的主题句。下一句指出，做好一顿饭后，如果你打算留一些在接下来的几天里吃，马上把食物放进冰箱，接下来则解释了这样做的原因，因此D项“首先，你应该立即把剩菜冷藏起来”能概括本段主旨。
18. A 根据本段第一句可知，本段建议把食物分成小份。上一句提到，当你把食物放进冰箱时，需要时间彻底冷却食物；下一句提到，这也会减少你从冰箱里拿食物的次数。由此可推知，空处的内容也与把食物分成小份的好处有关，故A项“所以小份对此有帮助”符合语境。A项中的smaller portions是关键信息。
19. G 上文提到，一般来说，你可以遵循两小时/四小时的规则。如果某样东西从冰箱里拿出来最多两个小时，把它放回去是安全的；如果它在外面的时间超过了两个小时，就把它吃掉，然后把剩下的扔掉。由此可推知，空处的内容应与食物拿出冰箱的时间有关，故G项“如果它已经在外面超过四个小时了，它就开始成为一个隐患”承接上文，符合语境。G项中的four hours是关键信息。
20. C 根据本段第一句可知，本段与食物卫生的一般原则有关。根据下一句中的Besides可知，空处的内容应是其中一个有关食物卫生的一般原则，结合选项可知，C项“准备食物之前洗手是至关重要的”符合语境。
