Furthermore, there would be more and better employment opportunities 为什么要用be？

Question

Furthermore, there would be more and better employment opportunities
遇到好多句子会在里面写be的原型但是不止为什么

Answer 1

本来是There be句式。中间有了would， will的过去式。它们后面要跟动词原形，这就是语法规则叠加。译成汉语:而且会有更多更好的机会。

Answer 2

Furthermore, there would be more and better employment opportunities
这个句子中谓语部分的情态动词是would， would后跟动词原形，所以要用be。

Answer 3

这句话是there be句型，be是句子的动词。这里没有be动词，句型结构就是错误的。追问

那为什么要用原型，不用能am is are！？
