21-24分,感觉阅读有些答案很模糊啊 就说test 3 最后一题,without harmful environmental effects, 文章说了生态系统影响嘛supply one million users 这个只是本世纪second decade的估计呀 还有这句话的意思:There are also potential ecological drawbacks,since the water discharges will change the water temperature and disturb some marine habitats. Awater outflow temperatures could upset local marince life. Bwater discharges will disturb the ecology of the oceans. 大家觉得选什么。ETS应该不会有这种干扰答案的吧。 有人做过嘛,讨论下。 做过的人告诉下真确率吧,这个分数完全没有信心了。
