worth一般只用作表语
1．主语（物）+be +worth + 名词.
Hawaii is a beautiful place for travelling and worth a visit.夏威夷是个旅游胜地,值得一游.
The new bike is worth 350 yuan .这辆新自行车值350元.
2．主语（人）+ be +worth + (表示金钱或财产)名词.表示“拥有……财产”.
He is worth several million dollars .他有好几百万美元的财产.
How much is Mr.Green worth 格林先生有多少财产.
3．主语（物）+ be + worth +动名词.
The book is worth reading .这本书值得一读.
The car isn't worth repairing.这辆汽车不值得修了.
请注意：（1）在这种情况下,名子的主语与动名词在逻辑上有动宾关系,因此这个动名词应该是及物的（如上述例句）或具有及物性质的短语动词（如下述例句）.
The broadcast programme is worth listening to .这条广播节目值得一听.
The picture is worth taking good care of .那幅画值得好好保存.
（2）在这结构中,也可用先行词it 作主语.
It is worth repairing the TV set.这台电视机值修一下.
（3）worth前面,一般用well修饰,不用very.
The scheme is well worth a try .这个计划很值得一次.
4．Worth one's while "对……是值得做的,对……有益的,使感兴趣的”,主语是动名词或动词不定式.句首用it作形式主语.
（1） It is worth (one's) while + doing sth.值得某人做某事.
It is worth out while discussing the question again .这个问题值得我们再讨论一下.
（2） It is worth (one's)while +to do sth.=To do sth .is worth(one's)while.值得（某人）做某事.
It would be well worth your while to come to the meeting.来参加这个会议对你来说是很值得的.

其中,3.（2）在这结构中,也可用先行词it 作主语.
It is worth repairing the TV set.这台电视机值修一下.
应该符合你的问题需求.
如果是说某物（主语）是否值得花费代价,我觉得应为：
It is not worth spending money on.
两句话的It的含义是不同的.
