B. In other words, as clever a boy as
C. That is to say, as a clever boy as
D. In word, as clever a boy as
答案：
A. All in all, as a clever boy as
(答案→)B. In other words, as clever a boy as
C. That is to say, as a clever boy as
D. In word, as clever a boy as
解析：考查短语辨析。All in all 总而言之，In other words 换句话说，That is to say 那就是说，In word 总之，句意：汤姆和杰克都很聪明。换句话说，汤姆和杰克一样是聪明的孩子。as clever a boy as 第一个as 相当于so，所以选B。
