知识点：seem的用法&satisfy one’s needs
seem的用法
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：
①“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。
②“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：
Mrs Green doesn’t seem （或seems not ） to like the idea. 格林夫人似乎不太喜欢这个主意。
The children seemed to be eating something in the room. 孩子们好像正在房间里吃东西呢。
The young man seemed to have changed much. 这个年轻人看起来变化很大。
③“It seems + that从句”，其中it 是形式主语，that引导主语从句。例如：
It seems that no one knows what has happened in the park. 似乎没有人知道在公园里发生了什么事。
It seems to me that Mr Brown will not come again. 在我看来布朗先生不会再来了。
④“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：There doesn’t seem to be much hope of our beating that team. 看来我们战胜那个队没有多大希望。 There seems no need to wait longer. 看来没有再等的必要了。
