1.此句并没有语法错误.
该句为含有一个以省略的that为引导词的宾语从句,所以主句从句各有一个谓语.
定语从句才有所谓的关系代词.
2.句子写全为:
I found (that) the PH.D.program of your department quite attracts me.
1)主句:I found (that...)
主句主语为I
主句谓语为found
后面是其宾语(从句)
2)宾语从句:(that) the PH.D.program of your department quite attracts me
从句主语 the PH.D.program;
of your department为介词短语做后置定语修饰主语;
attracts为从句谓语;
me为从句宾语;
quite为从句状语.
