问题 The laser represents a true marriage between science and technology, the men who devised it were______engineers and physicists.
选项 A、spontaneously
B、simultaneously
C、instantaneously
D、homogeneously
答案B
解析 本题空格处是说这人是位工程师，同时又是位物理学家。simultaneously的意思是“同时”，符合题意。如：This event was almost simultaneous with that one．(这件事几乎是与那件事同时发生的。)其他三项“spontaneously自发地，本能地；instantaneously瞬间地；homogeneously相似地”都不正确。
