Question

【題目】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（用沸水燙）before you freeze them. 【2】, which affects nutrient levels and appearance of your veggies.

●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】本文主要介紹了一些冷凍的水果，蔬菜，肉類，湯類的保質(zhì)期。

【1】G 考查對上下文語境的理解�？涨暗囊馑迹宏P(guān)鍵是要知道冷凍食物是什么時候開始過保質(zhì)期。所以這里選G（每一種食物都沒有一個神秘的日期，但是它們有一般的參考可遵循。）與上下文一致。

【2】D 考查對上下文語境的理解。空前的意思是：蔬菜在冷凍前用沸水燙一下是有用的�？蘸蟮囊馑际牵哼@影響了營養(yǎng)水平和蔬菜的外觀。所以這里選D（那個過程的關(guān)鍵是阻止酶的過程。）與上下文一致。

【3】A 考查標(biāo)題句。根據(jù)后文出現(xiàn)的beef, turkey, veal, pork and lamb可知，這一段主要講的是生肉的冷凍。所以這里選A。

【4】C 考查對上下文語境的理解�？涨暗囊馑际�：家禽�？蘸蟮囊馑际牵呵谐蓧K的鳥的保質(zhì)期可達(dá)九個月。所以這里選C（整只鳥的保質(zhì)期可達(dá)一年。）與上下文一致。

【5】F 考查對上下文語境的理解�？涨暗囊馑际牵耗切┖�有蔬菜、谷物、肉、面或者奶酪的湯，砂鍋，辣椒的在冷凍箱的保質(zhì)期可達(dá)兩，三個月。所以這里選F（這要取決于是否他們是近期購買的新鮮冷凍的食物。）與上下文一致。
