1、Had I heard your advice, I'll not make such a big mistake.2、So excited he was when he got a prize that he couldn't say anything.
北条真理
第一句 选 A要和后面的从句保持一致（so....that 结构），太.....以至于......翻译：So little did I knew about this theory that the lecture was totally beyond me.我对这一理论知之甚少，以至于演讲完全超出了我的理解范围。第二句选 Che will begin to operate the machine.（他将开始操作这台机器）这个动作发生在 after he has learned this skill（在他学会了这个技能之后，要注意这是一般时态）的后面，所以用将来时态翻译：Only after he has learned this skill will he begin to operate the machine.只有在他学会了这项技能之后，他才开始操作这台机器。
