问题     近来新闻中经常提及转基因食品。你可以从字面意思得知，转基因食品就是用产生了基因变化的生物生产的食品。这种改变可能是引入一个从其他物种中提取的基因。
    最近，关于转基因食品的有争议研究引起了公众关注。转基因的好处包括它能够培育出抗病植物。另外，转基因也可以增加天然物种中所缺失的维生素。
    然而，转基因食品的引进有可能是灾难性的。从一个物种中提取基因并植入另一物种被认为是一个巨大的飞跃，这也许会带来一些可怕的后果。现在还没有定论。但是，所有的转基因食物在推向市场前都要经过严格的评估。
选项
答案     Genetically modified foods (GM foods) are often mentioned in the news lately. You can literally get the meaning of genetically modified foods, which refer to the foods produced from organisms with specific genetic changes. The modification may be adding a gene from a different species to create a transgenic plant.
    Recent controversial studies on genetically modified foods have drawn attention of the public to the issue. The benefits of genetic modification include being able to breed disease resistant crops. What’s more, it can also add those vitamins that some natural varieties may lack.
    However, the introduction of genetically modified foods can be disastrous. The science of taking genes from one species and inserting them into another is supposed to be a giant leap forward, which may result in some terrible consequences. There hasn’t been any final conclusion yet. However, all GM foods should be strictly assessed before being allowed on the market.
