with sth done 复合结构, 随着到2050年65岁以上人数预计增长到将近两倍不能改成as如果用as,应改为As the percentage of people over 65 is expected to nearly double by 2050

不能用as,as和with虽然都有随着的含义,但是as 后要跟一个完整的句子,而这是一个with的复合结构,我想你的这句话后一定是个“,”,后面还应该有内容,实际上可以把它理解为with( the percentage of people over aged 65) which is expected to .....其中()的是宾语,也就是with +宾语+宾补结构,过去分词expected 相当于which is expected to 相当于被动go agaist 违背 of+名词=相应的形容词eg. What you said is of little importance.= What you said is not important.
