问题 It was in 1930s that scientists first ______ the idea of the atom bomb.

选项 A、imagined
B、contemplated
C、reckoned
D、conceived

答案D

解析 词辨义。imagine意为“想象”,如:Imagine you’ve been shipwrecked.(想象你遭遇到船舶失事。)contemplate意为“盘算,思考”,如:The young surgeon contemplated the difficult operation of kidney transplant.(年轻的外科医生为肾移植这一棘手的手术苦思冥想。)reckon意为“认为,测算”,如:She reckoned the money we owed her.(她算出我们欠她的钱。)conceive意为“构想出,设想”,如:Half a century ago it’s difficult to conceive of travelling to the moon.(在半个世纪前去月球旅行是难以想象的事。)本题的时间是20世纪30年代,所以在当时这只能是一个假想,故选D)。
