应该没有语法错误。with the rapid development of economy as well as society在百度上可以搜到其他相似的句子,见http://tool.xdf.cn/juku/889113.html;large firms have offered job opportunities in mounting numbers这半句也无误,in mounting numbers表示“越来越多的……”。来自:求助得到的回答
with the rapid development of 语法没错,但表达的是结果,与后面主句large firms have offered ...没有必然关系。而用with rapid developping of ...表过程,则与后句呼应。 as well as 放此处不当,容易使重点转移,应用and 代替。
