Question

这个句子成分应当如何分析？

My mind wasn’t on what he was saying so I’m afraid I had missed half of it.

这个句子成分应当如何划分？

我的理解是这样的：
首先，主句的结构是 主语+系动词+介宾短语的结构（主系表）
what he was saying是宾语从句，做为介词on 的宾语
so I’m afraid I had missed half of it.是状语从句。

这个说法对吗？

另外，如果单独看I’m afraid I had missed half of it这个句子的话，应该属于什么结构？afraid 是形容词啊，I had missed half of it做什么成分了?
so I’m afraid I had missed half of it 这句中是so引导的状语从句，还是说so简单做连词？

另外 I’m afraid + 介宾短语 这个属于什么句型？ 算是主谓宾结构吗？可是 be afraid算是动词吗？

Answer 1

My mind wasn’t on what he was saying 和 I’m afraid I had missed half of it 都是宾语从句的用法

I’m afraid I had missed half of it 省略 that
I’m afraid （that）I had missed half of it 这里是that引导的宾语从句
My mind wasn’t on what he was saying 这里what引导宾语从句

My mind wasn’t on what he was saying so I’m afraid I had missed half of it.可以这样分开看My mind wasn’t on what he was saying
so I’m afraid I had missed half of it
