There seems to have been ...好像有.


选【B】


很高兴为您解答,【曾飞非】为您答疑解惑
如果本题有什么不明白可以追问,to have won the first prize in the fierce competition这个是形式主语吗？？？看错了选【B】There seems to have been ... 好像有....为什么不能选”It"to have won the first prize in the fierce competition 这句话不可以是形式主语吗？？？there be是完成时态的标志，所以这里用there have been。
