exploration 探索，探究
句子解析：
还是not…any more than 结构，还是把句子拆分：
A= But his primary task is not to think about the moral code which governs his activity
B= a businessman is (not) expected to dedicate his energies to an exploration of rules of conduct in business.
参考译文： 但是，他的首要任务并不是考虑支配自己行动的道德规范，就如同(我们)不能指望商人会致力于探索行业规范一样。
KK友情提示： Not…any more than, 从结构上我们已经掌握了，再从表意功能上看，我们其实可以知道，这个结构很多时候就是为了把两个 表示否定的句子连接起来而已。第二个句子所表述的事实往往是被读者所熟悉的，和接受的，这样能更好的表达第一 个句子的意思。
再提醒一下，这个结构中的not,可以不是not，可以是其他的否定词，no,few,hardly, never，nobody都可以;
同学们试着看看下面的句子:
Nobody with any sense expects to find the whole truth in job advertisement any more than he expects a man applying for a job to describe his shortcomings and more serious faults.
