答
主从句两者时态要一致。
若要用Seemed后面的Have就改为Had
答
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
答
因为"it"是单数,而且表示的是一般时态
答
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。
答
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
