雅思大作文范文：食品离开农场送到千里之外消费者手里

雅思大作文题目：

Today,food travels thousands of miles from farms before it reaches consumers in urban areas.

Why is this the case?Is this a positive or negative trend?

【话题分类】

社会生活类

【题目解析】

题目大意：今天的食品在离开农场后，送到千里之外的城镇消费者手上。为什么会发生这种情况？这是一个正面还是负面的趋势？

题型特点：两问组合类题型，需要分别对两个部分展开回应，才能达到完整扣题效果。

本文结构：开头段引入话题、第一个主体段回应第一个问题（解释原因）、第二个主体段回应第二个问题（评价现象）、结尾重申观点。

难点：题目讨论的核心是现在食物生产和运输和全球化的现象，需要围绕此关键词进行论述。

【写作思路】

开头段：在过去，大多数肉类、蔬菜和其他食品都是在本地采购的。然而，现在普通消费者可以方便地买到来自世界其他地区的原材料和预先准备好的物品。虽然这是近几十年来城市扩张和物流进步的自然产物，但这是一个日益严重的问题，会对环境和经济产生深远影响。

主体段1：食物里程增加有两个主要原因。一个主要因素是全球范围内前所未有的城市化趋势。另一个因素是长距离分销系统的改善，使消费者可以不受季节影响购买相同类型的产品。

主体段2：全球食品分配网络，尽管在满足城市人口日益增长的饮食需求方面很有价值，但也会在两个不同层面上产生负面影响。其中最受关注的是伴随而来的生物风险。另一方面的影响则是对农业经济的干预。

结尾段：总而言之，食品运输距离的增加是城市扩张和相关资源分配需求的结果。如果不仔细监测和管理，这可能会对粮食的可持续性和市场稳定性产生不可逆转的后果。

【参考范文】

In the past,most meat,vegetables and other food items were sourced locally.Today,however,the average consumer has convenient access to ingredients and pre-prepared items from other parts of the world.While a natural product of urban expansion and logistical progress in recent decades,it is a growing concern that can have profound environmental and economic impacts.

There are two main reasons for the increased food miles.The main one,as some experts suggest,is the unprecedented trend of urbanization across the globe.Having a larger population with greater spending power means regional agricultural systems,with limited volume and variety,are no longer sufficient suppliers,necessitating importation of food products from other regions.Another factor is the improved long-distance distribution systems that allow consumers to purchase the same type of produce regardless of seasons.Without this constant supply,it is unlikely that regions can take advantage of their own climatic and soil conditions to maximize outputs and compensate for others’seasonal shortages.

The global food distribution network,despite its value in satisfying the increasing dietary need of the urban population,can have negative impacts on two different levels.The one that attracts the most publicity is the accompanying biological risks.The focus on high-yield plants and animal species,as harmless as it may sound,can increase risks related to diseases,pests and pathogens and ultimately disrupt the natural balance in regional ecosystems.The other challenge brought by the intervention is economic in nature.Multinational corporations,by manufacturing and transporting food items at the lowest cost possible,eliminate competition from local farmers with ease,so the local agricultural sector is likely to suffer in the long run.

To sum up,the increased distance food travels are the result of city expansion and the associated need for resource allocation.If not carefully monitored and managed,this can have irreversible consequences on food sustainability and market stability.
