It seems (seem)that the children have changed a lot.
如果是【seemed】的话,后面就应该用had changed
时态要往前推一格
有不会的可以再问我

主从句时态搭配要一致。从句是现在完成时态,主句只能是一般现在时态。如果用seemed,从句只能是had changed。

主从句两者时态要一致。
若要用Seemed后面的Have就改为Had

因为后面的that从句使用的是have changed,现在完成时,必须和前面的保持一致,所以前面用现代时的seems。而不用seemed。如果用seemed,那么后面应该是had changed

因为"it"是单数,而且表示的是一般时态
