| 2. | Week 15 ( 06 / 05 / 07 ) debate ii : should we develop gm crops 大辩论ii :我们应该发展基改作物吗? |
| 3. | Defining the environmental risks of gm crops seems even harder than calculating their benefits 要界定基改作物对环境的害处,似乎比评估优点更为困难。 |
| 4. | In each case activists mistook ordinary plants for gm varieties . it ' s easy to understand why . in a way gm crops 在每个案例里,那些行动派都把一般作物误认为基因改造过的品种。 |
| 5. | Let ' s turn to the environmental effects of gm crops . what do you consider the most important benefits of the technology 我们回过头来谈谈基改作物对环境的影响。你觉得这个技术对环境最大的好处是什麽? |
| 6. | In the face of mounting consumer concern scientists are stepping up research into the consequences of bt and other gm crops 由于消费者的疑虑如排山倒海般而来,科学家正加速研究bt和其他基改作物对环境的影响。 |
| 7. | Today most gm crops mainly soybean corn cotton and canola contain genes enabling them to either resist insect pests or tolerate weed - killing herbicides 如今大部分基改作物都含有抗害虫或耐除草剂的基因,以大豆玉米棉花及油菜为主。 |
