在定语从句中,充当主语的连接词能省略吗?如果不能的话,那这句话A kinder approach of restructing would soften socail instability many fear would result from doubling jobless rate ,already at a record high.这里many fear 只能看做插入语,那would 后面的句子是作instability的定语从句,但是主语的连接词被省略了.

这认为many fear would result from doubling jobless rate , already at a record high是修饰instability 的吧，在此做的是同位语从句，类似于，It is the fact (that) it's your responsibility.

连接词作主语不可省略，作宾语或状语时可省

首先连接词在从句中作主语时是不能省略的,连接词（这里特指的是关系代词）只有在作宾语是可以省略.还有这句话是否可以考虑不是定语从句,而是一个同位语从句many fear would result from doubling jobless rate做的是...

主句是“A kinder approach of restructing would soften socail instability”
“many fear would result from doubling jobless rate ”是修饰instability的定语从句。
充当主语的连接词可以省略。
