一、英譯中： Crops produced through genetic engineering are the only ones formally reviewed to assess the potential for transfer of novel traits to wild relatives. When new traits are genetically engineered into a crop, the new plants are evaluated to ensure that they do not have characteristics of weeds. Where biotech crops are grown in proximity to related plants, the potential for the two plants to exchange traits via pollen must be evaluated before release. Crop plants of all kinds can exchange traits with their close wild relatives (which may be weeds or wildflowers) when they are in proximity. In the case of biotech- derived crops, the Environmental Protection Agency (EPA) and U.S. Department of Agriculture (USDA) perform risk assessments to evaluate this possibility and minimize potential harmful consequences, if any.（30 分）
