1、Just as on smoking, voices now come from many quarters insisting that the science about global warming is incomplete, that it\'s Ok to keep pouring fumes into the air until we know for sure。
正如像吸烟一样,来自许多评论的声音仍然坚持说关于全球变暖的科学是不完善的,在其完善之前可以继续往空气中倾倒废气。
2、Do you remember all those years when scientists argued that smoking would kill us but the doubters insisted that we didn\'t know for sure? That the evidence was inconclusive ,the science uncertain?
你是否记得这些年当科学家辩论说吸烟会导致我们死亡,而怀疑者坚持说我们不确信。那么证据不具有结论性,科学就值得怀疑吗?
