  tpo综合写作听力文本(部分内容):

  Sure, there is some benefit to planting genetically modified trees, but um, are these trees really as great as they first sound? When you examine the subjects closely, there are some serious problems and causes associated with the using of genetically modified trees.

  First, genetically modified trees may be resistant to one particular condition, but it doesn’t necessarily ensure their survival. You see: a typical non-modified tree population is genetically diverse. That means that for most threatening conditions, for climate, insects, and other pests, whatever, there will be at least some individual trees of any given species of tree that are resistant. So, even if most of one kind of tree are killed, those few resistant ones will survive and ensure the survival of that species of tree. But, genetically modified trees are genetically much more uniform, so if they are exposed to an environmental challenge they haven't been designed for, they will all die. So, if the climate changes or um,a new pest invades in area, the genetically modified trees will likely be completely wiped out.
