这个。。。seem有用于形式主语的用法,但是应为“It seems + that从句”的用法,其中it 是形式主语,that引导主语从句。例如:
It seems that no one knows what has happened in the park. 似乎没有人知道在公园里发生了什么事。
It seems to me that Mr Brown will not come again. 在我看来布朗先生不会再来了。
你的那个句子应为:It seems that a stongcompetition have been in China for school leavers to enter college or university
可以肯定,有 it seems to be的用法。
可以用it代替
