作物中抵抗害虫的基因会不会传播给周围的植物，从而长出需要更毒的农药才能根除的超级杂草？
Will pest-resistant genes in crops spread to surrounding vegetation and create super weeds that require more toxic chemicals to eradicate?
苏西：我自然喜欢，但是那种遗传而来的防御能力可能会传给同科植物，然后生出需要更毒的除草剂才能控制的超级杂草。
Susie: Naturally, but those inherent defences could spread to plants in the same family and produce super weeds that would require even more toxic herbicides to control.
