问题 What is said about global warming in the first paragraph?
What is the message the author intends to convey?

选项 A、Global warming is more of a moral issue than a practical one.
B、The ultimate solution to global warming lies in new technology.
C、The debate over global warming will lead to technological breakthroughs.
D、People have to give up certain material comforts to stop global warming.

答案B

解析作者观点题。最后一段提到，全球变暖的争议已演变成了道德问题，而实际只是工程技术问题。令人不安的事实是，如果我们不解决技术问题，我们就毫无希望。故选B(作者欲传达的思想是，全球变暖问题的最终解决办法在于新科技)。
