句子一：

　　For example, they do not compensate for gross social inequality, and thus do not tell how able an underprivileged youngster might have been had he grown up under more favorable circumstances.

　　句子分析：

　　第一、句子可以拆分為三段：For example, they do not compensate for gross social inequality, / and thus do not tell how able an underprivileged youngster might have been / had he grown up under more favorable circumstances.

　　第二、句子的結構：

　　1)主干結構是并列句they do not compensate for..., and thus do not tell...

　　第三、詞的處理：

　　hey 指示代詞，測試

　　compensate for 彌補

　　gross social inequality 明顯的社會不公

　　and thus 因此

　　ell 說明

　　underprivileged 貧困的、物質條件差的

　　under more favorable circumstances 在較好的環(huán)境下

　　例如，測試并不彌補明顯的社會不公，因此它們不能說明一個物質條件差的年輕人，如果在較好的環(huán)境下成長的話，會有多大才干。
