1. Scholars who once thought Native American literatures were solely oral narratives

2. Scholars thinking of Native American literatures once solely as oral narratives, and

3. Scholars who once had thought of Native American literatures solely as oral narratives and

4. Native American literatures, which some scholars once thought were solely oral narratives

5. Native American literatures, which some scholars once, thinking they were solely oral narratives

   Answer:A   想请问thought and were  是不是两个谓语啊 加上後面的understand不是有三个吗                                                                                                      

前面两个是从句的谓语，只有understand是主语的谓语/

Scholars  understand

who       thought

Native American literatures    were recorded

这是三对主谓。

very clear

对了，我发现think后面的从句经常没有加that,而是直接think +句子~

有人有关于这种可以引导省略that的宾语动词的总结么？
