这两个句子都是宾语从句。I think learning is fun。这么理解：主语的主语是：I, 主句的谓语是：think，主语的宾语是个句子：learning is fun。这整个句子作为谓语动词think的宾语。宾语从句一般由先行词that引导，也经常省略。完整句子为：I think that learning is fun。You can imagine the story is bad。同样是宾语从句：主句的主语是：you，主句的谓语是：image。宾语是整个句子the story is bad。完整句子为：You can imagine that the story is bad。
