有关Food & Technology的问题，虽然在具体的问法上有些许差异，但基本我们可以从technology对food的积极和消极影响两个大方面入手。需注意的是，因为是part3的题目，大家要尽可能去延伸自己的观点，而不是非常笼统地说technology让我们可以吃到更多种的食物或是technology导致我们的食物不那么健康。

说到科技对食物的积极影响，可能大家体会最深的便是某些特定季节的蔬菜水果如今一年四季都可以买到、吃到。除此之外，越来越发达的保鲜技术，不仅延长了食物的可食用期限，也让人们能够品尝到从千里之外运送来的异域食物。

相关表达：

food production/yields/output 食品产量

achieve higher yield 实现更高产量

protect crops from insects 保护庄稼不受昆虫侵害

minimise threats from pests 将害虫威胁降最小化

harm or devour crops 伤害或吞噬庄稼

a plague of locusts 蝗虫灾害

cause crop failure 导致谷物失收

increase the variety of crops 增加作物品种

heavy rain 大雨

drought 干旱

floods 洪水

crossbreed 杂交

cross-pollination 异花授粉

grow hybrid plants/foods 种植杂交植物/食物

combine two categories of plants 把两种植物结合起来

create patented varieties of… 创造新品种

grapefruit = a pomelo and a sweet orange 柚子（柚子和甜橙的杂交产物）

broccoflower = broccoli and cauliflower 椰菜花（西兰花和花椰菜的杂交产物）

E.g. New technology such as crossbreeding and cross-pollination increases produce varieties. With such technology, crop growers can create new types of fruits and vegetables, and therefore, consumers have more kinds of produce on their plates. Typical examples include a grapefruit, a combination of a pomelo and a sweet orange, and a broccoflower, a mix of broccoli and cauliflower.

E.g. In the old days, what people ate or whether people had enough food to eat was mainly subject to weather conditions. Natural disasters like heavy rain, floods and drought could result in inadequate food production. A plague of locusts could cause crop failure, leaving millions of people starving. But today, advanced farming techniques such as greenhouse farming have made crops more resilient to increasingly changeable climates, thus, helping achieve stable yields.

我们梳理了关于technology对food的积极影响，接着来看看，科技发展及应用对我们所食用的各类食物的消极影响。

如今，许多食物，尤其是加工食品、方便食品，食物添加剂、色素的使用都十分普遍，但这些添加剂或色素虽然是可食用的，不少研究都表明它们是存在致病致癌风险的。农民为了增加粮食产量，减少害虫对庄稼的破坏，可能会大量使用农药，给牲畜使用激素等，而这些药物残留危害人们的健康。再者，我们现再也有越来越多的报道，某些生产商为了削减成本，使用人造食物（如肉、蛋白、纤维）冒充真正的肉类、蛋白或是利用某些添加剂、溶液将便宜的猪肉、猪血冒充牛肉或鸭血等。

相关表达：

packaged food包装食品

tinned/canned food罐装食品

processed food加工食品

heavy use of additives 大量使用添加剂

food colouring 食用色素

preservative 防腐剂

edible 可食用的

pose risk to .. 对……构成威胁/有危害

health risk 健康风险/危害

increase food yields 增加粮食产量

use large amounts of fertiliser/pesticide 使用大量的肥料/杀虫剂

use of growth hormones 使用生长激素

make cattle grow more quickly 使牛长得更快

result in a health risk for consumers 对消费者健康造成威胁

reduce/cut costs 降低成本

duck blood 鸭血

fake honey 假蜂蜜

artificial sweeteners 人工甜味剂

plant-based proteins 植物性蛋白

fake seasoning 假造的调味料

industrial salt 工业用盐

E.g. Livestock farmers sometimes use growth hormones to make cattle, pigs, and goats grow quickly. By doing this, they can reap profits faster, but at the cost of health risks to consumers. In poultry farming, a similar practice is used.

E.g. People are increasingly seeking reduced-fat, low-calorie, sugar-free foods and drinks. Because of this, manufacturers often add artificial sweeteners to their products. However, artificial sweeteners, like Aspartame[阿斯巴甜], can increase diabetes and obesity risks. There is also scientific evidence that these sweeteners may cause migraines[偏头痛] and digestive problems[消化问题].

E.g. Foods we consume today contain preservatives, additives, and colouring. These chemical substances are added to make foods taste better and extend their shelf life. However, the nutritional value of these foods is lessened.

E.g. Modern technology in the food industry makes it possible for manufacturers to produce fake food. Let me give you an example. Due to the high cost of beef, some producers sell pork as beef. What they do is dip it in some solution[溶液]. An hour later or so, the pork looks pretty like and smells like fresh beef. Another case in point is honey. Some producers simply mix sugar, water, alum[明矾] and colouring to make fake honey, but they sell it as real honey. Similarly, quite a few factories sell fake Tofu, a mixture of various cheap chemicals.
