如题所述
因为seem 为 表像系动词,后可以接名词,形容词,介词短语,分词,不定式,从句。
seem to be是主系表结构。
“主语+ seem +(to be )+表语”,表语多为名词或形容词,有时是其他的词或短语,以说明主语的特征或状态。例如:
Tom seems (to be ) a very clever boy.
汤姆看上去是一个非常聪明的男孩。
The man over there seems to be a new teacher.
那边的那个人看上去像一个新老师。
Mr Black seemed to be quite happy.
布莱克先生好像十分快乐。
This small town seems changed a little.
这个小城镇似乎有点儿变化。

seem 之后可以接不定式:seem to do sth.,共同构成谓语部分。此外,不定式与seem发生的时间是有先后的,这种“先后关系”,不定式要通过使用不同的“体”(也叫“式”)表现出来。例如:
1. 一般式:It seems to rain this afternoon.
一般式往往表示其动作在谓语动词之后发生。例句说明,“今天下午看起来要下雨。” rain应在seem之后发生。
2. 进行式:It seems to be raining outside.
进行式往往表示不定式的动作与谓语动词同时发生。例句说明,“外面好像正在下雨。”(指在室内听见外面有下雨的声音或迹象), rain和seem同时发生。
3. 完成式:It seems to have rained last night.
完成式表示不定式的动作发生在谓语动词之前。例句说明,“昨晚好像下了雨。”(指早晨起床后发现地面潮湿,有下雨的迹象,才做出如此判断), rain 发生在seem之前。

二.seem+doing 也是好象的意思.不表示虚拟.
