Question

How long can you safely freeze food?

Frozen food lasts indefinitely. But does that mean the raw chicken you bought on sale and froze will taste as good a year from now as it will three weeks from now? No. You can cook up that chicken a year later and it won’t harm you, but its taste and texture will be diminished. The key is knowing when frozen food starts to lose quality.1..

Fruits and vegetables.

You can freeze most vegetables and non-citrus fruits for about 8 to 12 months, according to the National Center for Home Food Preservation. (You can freeze citrus, too, but you need to take some extra steps.) Vegetables will benefit from blanching（用沸水烫）before you freeze them. 2., which affects nutrient levels and appearance of your veggies.

3.

●Ground beef, turkey, veal, pork and lamb: For best flavor and texture, these ground meats are best used within three or four months of being frozen.

●Steaks and chops: These cuts of beef, veal, lamb or pork can be frozen for six to 12 months before losing quality. Chops of these meats start to lose quality after four to six months.

●Poultry: 4. ; pieces of birds keep their quality for up to nine months.

●Fish: For best quality, fatty fish (salmon, tuna) should be consumed within two to three months. Lean fish (cod, flounder) should be consumed within six months.

5.F

【解析】本文主要介绍了一些冷冻的水果，蔬菜，肉类，汤类的保质期。

1.G 考查对上下文语境的理解。空前的意思：关键是要知道冷冻食物是什么时候开始过保质期。所以这里选G（每一种食物都没有一个神秘的日期，但是它们有一般的参考可遵循。）与上下文一致。

2.D 考查对上下文语境的理解。空前的意思是：蔬菜在冷冻前用沸水烫一下是有用的。空后的意思是：这影响了营养水平和蔬菜的外观。所以这里选D（那个过程的关键是阻止酶的过程。）与上下文一致。

3.A 考查标题句。根据后文出现的beef, turkey, veal, pork and lamb可知，这一段主要讲的是生肉的冷冻。所以这里选A。

4.C 考查对上下文语境的理解。空前的意思是：家禽。空后的意思是：切成块的鸟的保质期可达九个月。所以这里选C（整只鸟的保质期可达一年。）与上下文一致。

5.F 考查对上下文语境的理解。空前的意思是：那些含有蔬菜、谷物、肉、面或者奶酪的汤，砂锅，辣椒的在冷冻箱的保质期可达两，三个月。所以这里选F（这要取决于是否他们是近期购买的新鲜冷冻的食物。）与上下文一致。
