Question

请各位高手帮我分析一下这个句子的结构

Sure that I had passed the test.参考书上说可以将其看成
Being sure that I had passed the test. or
I was sure that I had passed the test. 作为一个因果复合句，但是哪一部分是主句，哪一部分是从句。如果 I had passed the test是主句，那么that是一个什么成份，以前好像没听说过主句还需要用that来引导。
如果I was sure是主句 那么that后的句子应该做什么成份来理解

Answer 1

Sure that I had passed the test

意思是 我确信我通过了这个测试

1 因为前后主语一致 都是I 所以可以看作是非谓语 (Being sure ) 的省略

Being sure that I had passed the test

2 I was sure that I had passed the test. 作为一个因果复合句

我很肯定,也就是我确信 为什么这么说呢 因为经历了这次测试 而我想我通过了 I was sure是主句.that 在此引导宾语从句 也是一种省略

Answer 2

I was sure that I had passed the test.中"I was sure"是主句.that 在此引导宾语从句, 全句是I was sure that I had passed the test.

Answer 3

I was sure that I had passed the test.中I was sure是主句.that 在此引导宾语从句,可以省略为I was sure I had passed the test.
Sure that I had passed the test.→Sure,I had passed the test.

Answer 4

这句的意思是我通过考试是一定的
主语是it's sure that I had passed the test
this is my opinion

Answer 5

Sure that I had passed the test.我想是个省略句，省了i was
