1.seem+形容词或名词（不接副词）
Everything seemed easy.
She always seems(to be)sad.
2.seem+不定式
I don't seem to be quite myself today.
3.seem+like(介词）＝seem to be(跟like但不跟as）

It seems like months since I saw you last time.
4.it+seem+that从句

It would seem tha something is wrong.
注：从句可以变成简单句,意思不变.
It seemed that no one was in that room.＝No one seemed to be in that room.
5.There+seem
There seems no need to wait longer.
6.it+seem+as if
It almost seemed as if the good man were trying to eeach us all he knew at the last lesson
可以看出没有sb seem as if 和there seem that 的用法.
2.opened是过去分词形式的形容词作宾语补足语,missing是现在分词形式的形容词作宾语.
因为miss是不及物动词,things和miss存在着逻辑上的主谓关系,所以用表示主动的ing分词.
