I provide a service that people can do without when they’re concerned about saving some dollars.如题,定语从句中,that在定语从句中作宾语,可以省略吗?如果省略,变成I provide a service people can do without...这样正确吗?求高手指点!谢谢啦!~

是作为介词without的宾语，定语从句中若关系代词that 和which作为宾语，则可以省略

可以省，请参考以下资料，若有所帮助，请采纳！
下几种情况不可省.
宾语从句为虚拟语气时.如He said that we should take more exercise.
宾语从句为两个,前一个引导词可以省略.后面的不能.
宾语从句中还有其它从句时不能省略.
在定语从句时先行词作宾语时可以省略关系代词that
The toy (that)I bought yesterday is very good

I provide a service that people can do without when they’re concerned about saving some dollars.
首先,我不得不说,你真细心!这种探求精神正是学习所需!
其次,理论上讲,【在口语和非正式语体中,关系代词在从句中作宾语时经常省略】.如：
The story (that/which)he told us is instructive.
按照此语法补充,你所给的句子【在口语和非正式语体中时】,that可以省略.
但是,【如果省略关系代词容易导致误解或费解时】,最好不省略.因为,语言的主要功能是交际,准确的传达信息才是终极目的.
最后,需补充的是,所给句子里,如果将介词without提前,那关系代词需用which,且绝对不可省略.即：
I provide a service without which people can do when they’re concerned about saving some dollars.
