produce a harvest的主语应该是什么

3 produce a harvest的主语应该是什么

The real breakthrough took place when farmers began to cultivate crops along the floodplains of river systems. The advantage was that crops grown in such areas were not as dependent on rainfall and therefore produced a more reliable harvest.

曹老师您好！在阅读过程中看到上文中的句子，它的后半句：produced a more reliable harvest（以下简称produce a harvest）作者没有写明主语。按理应该去本句中的前半句寻找主语。根据主语的名词性质和and的并列特性，我觉得本句主语应该是the advantage和crops这两个词中的一个。但是我去WR上问了一下，有人说crops能做produce a harvest的主语，有人说crops不能做produce a harvest的主语，有人说原文里被省略掉的主语是areas……

请教一下曹老师

1、句中produce a harvest的主语是什么？

2、抛开本句，在其他情境下，produce a harvest的主语是否可以是人/地区/某种作物/某种农具或用品/某种技术或操作/某种气候？

3、类似文中这种省略主语的句子（非比较结构导致的对应项省略），主语是不是一定在本句之内？有没有可能是主语出现在上一句？或者作者想用it作主语（it指代前半句），it可以省略？

本句不存在省略主语的问题。作者无疑是用crops作produced的主语。至于crops是否可以作produced的主语是另一回事。以下是COCA语料库部分用crops作主语、produce作谓语的例句。

In the United States, corn crops produced about a billion gallons of ethanol in 1992.

When was the last time our crops produced even a little more than what we need to fill our own stomachs?

Each year, humans, livestock, and crops produce approximately 38 billion metric tons of organic wastes worldwide.

Afghanistan's poppy crops produce the raw opium used to make 90% of the world's heroin.
