谁能帮解决这道英语改错题：
i don"t have enough time to do that I"M interested in even on weekends or holiday.麻烦尽可能详细点.,

这道题是考察宾语从句的,do是及物动词,所以后面应该跟宾语,这个宾语因为是个句子,所以应该有引导词.句子中的that算是引导词,但是句子I'm interested in没有宾语,所以这个引导词还应该作in的宾语,这样子就应该把that改成what.试比较：
I know what you are interested in.
I know (that) you like him.

that换成what，若interested in中in前置,则用which,否则用what
