意群训练： Gutman argues convincingly that the stability of the Black family encouraged the transmission of —and so was crucia l in sustaining —the Black heritage of folklore , music, and religious expression from one generation to another , a heritage that slaves were continually fashioning out of their African and American experiences .

标志： Gutman argues convincingly that the stability of the Black family encouraged the transmission of — and so was crucial in sustaining —the Black heritage (of folklore, music, and religious expression)/from one generation to another/,［a heritage (that slaves were continually fashioning out of their African and American experiences)］.

译文： G令人信服地论证道 ，黑人家庭的稳定性 鼓励了 ——因此也在后者的保持上起到了重要的作用 ——（包括民间传说、音乐及宗教表达的）黑人遗产 /从一代到另一代的/传播 ，［这是一个（奴隶们不断地从其在非洲和美国的经历中塑造出来的）遗产］。

解释： 在that引导的宾语从句中，encouraged 的宾语the transmission of the Black heritage 被同时表示并列和转折的and so 分开，给读者造成了阅读上和理解上的困难。最后一个逗号后面的部分是修饰前面的Black heritage的同位语。
