Question

请分析一下这句话的语法结构，我怎么看不懂？

The more people there are and the worse their living conditions, the greater the possibility for all kinds of social problems.

Answer 1

The more people主 there are谓 and the worse表 their living conditions 主（are系动词：省略), the greater表 grows（还有个grows系动词) the possibility主 for all kinds of social problems定语 .
the+比较级，the+比较级 结构
人口越多，生活条件越差，出现各种社会问题的可能性就越大。

可是原文中没有grows呀

追答

应该有的。

Answer 2

两个比较级结构：越怎样，就越怎样，为了强调，倒装了。
意思是：人口越多，且生存条件越差，各种社会矛盾的可能性就越大。
