问题 Research should continue on controlled nuclear fusion, but no energy program should be premised on its existence until it has proved practical.

选项 A、focused
B、concentrated
C、agreed
D、based

答案 D

解析本题意为“我们应该继续核扩散控制的研究，但不能将能源项目建立在其存在的基础上(前提下)，除非已被证明可行”。premise作为及物动词，其意思是to base a theory，argument，etc．on an idea，thought，or belief；agree的意思是“达成一致意见”；focus的意思是“关注，集中”；concentrate的意思是“关注，集中”；base的意思是“基于”。所以D是正确答案。
