1） 一个句子由一个基础句式引出以后，再逐渐增加具体细节（通常是以独立结构和分词短语形式出现），使基础句的内容得到补充或深化，这种句子即称渐进句（Cumulative sentence），即逐渐进一步说明的意思。例如：
The fall came early that year, the trees turning bare overnight, their yellow leaves scattered by the winds.
（Arnold Lazarus H. Wendell Smith）
Geiser serves his regular customers with special care, scraping the tops of steaks for those who insist on it, handing free frankfurters to the little tikes, adding an extra quarter pound of sausage to the order.
（Bizzell et al.）
2） 渐进句通常是由基础句提出整体或一般的概念，然后从整体到局部，从一般到个别，通过修饰语进一步加以说明。基础句的位置通常在句首，但也可能根据具体情况放到两个修饰短语之间或几个修饰语的最后面。例如：
Careening out of the lot, the car rumbled down the deserted alley, weaving from side to side.
（Leonora Woodman）
Their hair mussed, their clothes wrinkled, their eyes dull and half-shut, they had the look of the recently sick.
（Leonora Woodman）
