第一,划出定语从句和状语从句: since energy pinch will make it difficult to continue agriculture in the high-energy American fashion// that makes it possible to combine few farmers with high yields.
第二,划出介词短语:in the high-energy American fashion//
第三,句子的结构分析:
(1)主句是This will be particularly true
(2)since是引导时间状语从句,本句主语是energy pinch will make it difficult to continue agriculture;in the high-energy American fashion是宾语补主语;that 后接定语从句,修饰前面the high-energy American fashion。
