【翻译原文】

转基因食品（genetically modified foods）是通过基因工程的方法对生物体的DNA作特定改变并由此产出的食品。这些技术允许引入新的作物性状，对于食物基因结构的掌控也比之前的方法，如选择性育种、诱变育种（mutationbreeding）大。中国已经成为世界上最大的大豆（soybean）进口国，购买60%的全球交易大豆。这些进口大豆大部分是转基因品种。在中国，有对关于转基因食品的激烈的公开辩论。

【表达难点】

1.转基因食品是通过基因工程的方法对生物体的DNA作特定改变并由此产出的食品：这句话较长，经分析其主干为“转基因食品是……食品”，即Geneticallymodified foodsare…foods.“通过基因工程的方法”可作方式状语，放在句子最后，即using themethods of geneticengineering；“对生物体的DNA作特定改变”可译为have had specific changes introduced into their DNA。

2.这些技术允许引入新的作物性状，对于食物基因结构的掌控也比之前的方法，如选择性育种、诱变育种大：“允许引入……”翻译为allow the introduction of…；“新的作物性状”可用new crop traits表达，trait表示“特性，性状”，“对于……的掌控”可译为control over…；“选择性育种、诱变育种”可译为selective breeding and mutation breeding.

Geneticallymodified foods are foods produced from organisms that have had specific changes introduced into their DNA using themethods of genetic engineering.These techniques have allowed the introduction of new crop traits aswell as a far greater control over the food’s genetic structure than previousmethods such as selective breeding and mutation breeding.China has become the world’s largest soybean importer，buying about60%of the globally traded soybeans.Most of those imported soybeans are genetically modified varieties.In China，there is a fierce public debate on geneticallymodified food.
