哎...孩子,你题目铁定抄错了,应该是The most important thing is hard-working ,I think. 或者I think that the most important thing is hard-working.The most important thing 是主语,所以说你肯定抄错了
The most important thing is hard-working ,I think. I think是插入语,强调的是前半句The most important thing is hard-working
I think that the most important thing is hard-working. think是动词,就是说是谓语,that后的句子think 的宾语从句
