看到另外的帖子里的解释,觉得下面这个解释比较合理,COPY至此,供探讨 我最先也是选的A,后来跟c比较, 这是我的想法: the seeds themselves are quite expensive, and the plants require more fertilizer and water to grow well than normal ones - 这其实是作者摆的事实用来预测正因为这样可能农民不会用改良种子.
prediction就是Thus, for most farmers the savings on pesticides would not compensate for the higher seed costs and the cost of additional fertilizer.
However, since consumer demand for grains, fruits, and vegetables grown without the use of pesticides continues to rise, the use of genetically engineered seeds of this kind is likely to become widespread. - 这是作者提出的consideration,就因为这样原来的prediction就被反驳了.
请探讨. |
