Question

I _____ _____ difficult to get up early. 我认为早起很困难

Answer 1

这句话it作形式宾语,真正的宾语是后面的不定式to get up early,而difficult 是宾语补足语,即

I think it difficult to get up early.

还原成 主+谓+宾+宾补的句型是

I think to get up early difficult.

因为to get up early这个宾语太长了,为了句子结构的平衡,把它放在后面,前面用it作形式宾语,这句话的意思是：我认为早起是有困难的.

当然,也可以变成宾语从句,即

I think it is difficult to get up early.

祝新年快乐!
