It is of interest to note that the US consumes more than one-half of the world's supply of energy,the continent of Asia only 1/20.
参考答案:
要点:that引导的句子是note的宾语从句。该宾语从句由两个子句构成,一个是the US consumes more than one-half of the world's supply of energy,另一个是the continent of Asia only 1/20。后一个子句是省略句,补全为(and)the continent of Asia(consumes)only 1/20 (of the world's supply of energy).翻译时应把省去的部分补全。of interest相当于interesting。
