Hey sue! The highlighted part is just what my thoughts are, and that is expressed clearly in the original sentence in our group. The only difference is that you described "lost" which referred to in the second sentence as "notional verb", but I stated it as "predicate verb(谓语动词)" So I think it is just a misunderstanding. But it doesn't matter, which indicates that you are extremely right and I also didn't make mistakes. So we are both right haha. Anyway I really appreciate your help. Thank you a million.
