Fish, for example, live and breed according to their own life pattern. Human "producers" then come with nets and fishing poles to take the fish from the water. In our specialized world, however, it is not always possible to let our food grow in its own way. A relatively small number of people are responsible for producing large quantities of food. In order to perform such a function effectively, it is necessary for them to raise cattle and grow crops in a fairly concentrated area. Fishing, livestock(家畜)breeding, and fruit, vegetable, and grain growing are among the more commonly known food-production industries. 参考答案: 作为我们食物来源的许多动物和植物,无需人的帮助也能自行繁殖。例如鱼按照自己生活方式生长和繁殖, 所谓人类生产者只是 用渔网和渔杆将鱼从水中捕捞上来而已。 但是在我们这个专业化了的世界里,我们不可能总让食物以自己的方式自然增长。较少数量的人力要负责 生产大量的食物。为了有 成效地履行这一职责,他们有必要在相当密集的地区饲养家畜和种植农作物。 养鱼,饲养家畜以及种植水果、蔬菜和粮食都是人们更普遍熟悉的食品生产业中的一部分 作为我们食物来源的许多动物和植物,无需人的帮助也能自行繁殖。例如鱼按照自己生活方式生长和繁殖, 所谓人类生产者只是 用渔网和渔杆将鱼从水中捕捞上来而已。 但是在我们这个专业化了的世界里,我们不可能总让食物以自己的方式自然增长。较少数量的人力要负责 生产大量的食物。为了有 成效地履行这一职责,他们有必要在相当密集的地区饲养家畜和种植农作物。 养鱼,饲养家畜以及种植水果、蔬菜和粮食都是人们更普遍熟悉的食品生产业中的一部分
