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)。
