seem在课本中多次出现，基本含义是“似乎；好像；仿佛；看来”等，可作系动词或不及物动词。为了帮助大家掌握该词，现将其主要用法小结如下：
一、seem可与形容词、名词、不定式（短语）、分词及介词短语搭配。
1. seem 形容词。如：
She seems quite happy today. 今天她似乎很高兴。
2. seem 名词。如：
That seems a good idea. 那似乎是个好主意。
3. seem 不定式（短语）。如：
He seems to be thinking about something. 他似乎正在考虑某事。
The policeman seemed to have known the truth. 那个警察似乎早已知道事情的真相。
注意：（1）不定式是to be并以名词或形容词作表语时，to be通常可以省略。这样就变成1、2的用法。如：
She seems (to be) quite unhappy. 她看起来很不高兴。
He seems (to be) a fool. 他好像是个傻子。
（2）seem后跟不定式时，要注意不定式所表示的动作发生的时间，以此来确定不定式的时态。如3中的to have known为不定式的完成时。
（3）seem的否定式可在不定式前直接加not或借助do的相应否定形式来表达（放在seem前）。如：
They seemed not to know each other. 他们看起来好像互不认识。
She doesn’t seem to like the idea. 她似乎不太喜欢这个想法。
4. seem 分词。如：
He seemed pleased at what I said. 听了我的话，他似乎很高兴。
The news seems exciting. 消息似乎很激动人心。
5. seem 介词短语。如：
They seemed in high spirits. 他们似乎情绪高涨。
二、seem常用于it作形式主语的结构，即It seems / seemed that ...，表示“看来……；似乎……”。如：
It seems that he was late for the train. 看来他没赶上火车。
注意：（1）在这一句式中，常可省去that。
（2）seem后有时可跟形容词。如：
It seems impossible that he will be here tomorrow. 明天他来这儿似乎是不可能的。
三、seem常用于由as if / though引导的从句中。如：
It seems as if somebody is calling you. 好像有人在叫你。
It seems as though he were very stupid. 看来他似乎很笨。
注意：在as if / though引起的从句中，如果说的是非真实的情况，从句谓语用虚拟语气，如上句he were very stupid。如果所述的情况实现的可能性较大，则从句的谓语常用陈述语气。
四、seem常用在It seems / seemed to sb (that) ...结构中，这种结构常用来表示“行为”的主体。如：
It seems to me that they are right. 我感觉他们是对的。
五、用于There seems / seemed to be n. (主语)中。如：
There seems to be no work for you to do now. 看来现在没有什么工作需要你做了。
注意：（1）在这一结构中，seem表示“似乎有；看来有”。如：
There seems to be a lot of things to do. (=It seems as if thereare a lot of things to do.) 似乎有很多事情要做。
（2）这一结构的否定形式为There seems / seemed to be no n.或There doesn’t / didn’t seem to be n.。如：
There doesn’t seem to have been any difficulty on this question. 在这个问题上似乎没出现什么困难。
