seem可用作连系动词或不及物动词,意为“似乎；好像”,其常见用法现归纳如下：
一、“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：

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.

二、“主语+ seem + 不定式”,此句型中的seem与不定式一起构成复合谓语.例如：

The young man seemed to have changed much.这个年轻人看起来变化很大.
三、“It seems + that从句”,其中it 是形式主语,that引导主语从句.例如：

It seems to me that Mr Brown will not come again.在我看来布朗先生不会再来了.
四、“There + seem to be +名词”,其中to be 可省略.seem 的单复数形式要根据后面作主语的名词的单复数形式而定.例如：
