(2) Grazing peacefully, the goats in the farm were unaware of the approaching hunter. (现在分语短语+简单句)

(4) There were goats grazing peacefully in the farm, unaware of the approaching hunter. (简单句+形容语短语)
(5) As the goats grazed peacefully in the farm, they were unaware of the approaching hunter. (原因副词从句+主句)
(1)和(5)的句式最常见;如果加上其他三种互相交替，句子不是更多样化吗?最后，看看这两个句子要如何多样化呢?
