问题 A scientific law is liable at anytime to need______; that is an eternal truth.

选项 A、modifying
B、changing
C、revising
D、adjusting

答案A

解析 A项“modify修改”符合题意,如:The equipment may be modified to produce VCD sets.(这设备可以经过改装用来生产光碟机。)其他三项“B项change变换,替换,转换;C项revise重新考虑并修订,修正;D项adjust调节,调整”都不正确。本题的意思是科学定律随时都可能需要修改。因此A项为正确答案。
