It was only after the creation of the FAA that full-scale regulation of America’s airspace took place,and this was fortuitous,for the advent of the jet engine suddenly resulted in a large number of very fast planes reducing pilots’ margin of error and practically demanding some set of rules to keep everyone well separated and operating safely in the air.
　　難點解析
　　本句的難點在于對句子的邏輯關系的理解.首先要理解it was only after…that結構所表示的時間關系,并且要抓住連接詞for所表示的整個句子的因果關系,以及子句中resuted in、reducing…and practically demanding…等詞所表示的邏輯含義.
　　我們可以理一下句中的邏輯關系：首先FAA成立,然后是full-scale regulation出現(xiàn),但是這只是巧合,原因是the advent of…,暗指the advent of…是真正the creation of the FAA的原因.然后又介紹了the jet engine所帶來的一系列影響(a large number of…),這些影響又是如何導致進一步的影響(reducing pilots’ margin of…)和需求(demanding some set of rules).把這些關鍵點找到了,句子的含義就明朗了.
