理解長(zhǎng)句要先分析句式結(jié)構(gòu)：
主語(yǔ)：it
謂語(yǔ)：points out
賓語(yǔ)：some of ten potential challenges
補(bǔ)語(yǔ)：是一個(gè)定義從句：which exist if the poor as well as the rich are to benefit.
所以主句：it points out some of ten potential challenges
翻譯主句：.
從句：which exist if the poor as well as the rich are to benefit.
從句翻譯：如果窮人和富人同時(shí)將會(huì)收益,它（ten potential challenges)就會(huì)存在.
所以綜合主句和從句,并整理句式可得翻譯：
它指出十個(gè)潛在挑戰(zhàn)之中幾個(gè),如果窮人和富人同時(shí)將會(huì)收益時(shí),這些挑戰(zhàn)就會(huì)存在.
