The prime minister should be able to make a decision without having to explain all the whys and wherefores to a bunch of journalists.首相应该可以作出决定而不必要向一群记者解释原因。Robbie always asks the whys and wherefores when he is told to do something.如果要罗比做事,他总爱问个究竟。Even successful bosses need to be queried about the whys and wherefores of their actions.即使成功的老板也需要接受对其行动缘由的质疑。He prefers not to discuss the whys and wherefores of what exactly happened.他不愿去讨论事情究竟为什么发生。
