seem作系动词时有“似乎”或“好像”之意。seem表示对某事物做出判断时虽有一定的根据,但仍然有所怀疑,着重于说话人的主观感觉。下面是小编整理的一些关于seem的用法, 希望让大家更好地认识seem这个单词,提高英语水平。

seem在英语单词中的用法归纳

一、seem常用于it作形式主语的结构,即It seems / seemed that..., 表示“看来……,似乎……”。

It seems that nobody knew what had happened. 似乎没人知道发生了什么事。

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)在seem后间或可跟形容词。

It seems impossible that he will be here tomorrow. 明天他来这儿似乎是不可能的。

二、seem可与形容词、名词、不定式(短语)、分词及介词短语搭配。

1. seem + 名词

That seems a good idea. 那似乎是个好主意。

She seems a clever girl. 她似乎是个聪明的女孩。

2. seem + 形容词

She seems quite happy today. 今天她似乎很高兴。

3. seem + 不定式(短语)

He seemed to have known the truth. 他似乎早已知道事情的真相。

He seems to be thinking about something. 他似乎正在考虑某事。

Something seemed to be wrong with the train. 火车好像出了故障。

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。

He seems (to be) a fool. 他好像是个傻子。

She seems (to be) quite unhappy. 她看起来很不高兴。

2)seem后跟不定式时,要注意不定式所表示动作发生的时间,以此来确定不定式的时态。如3中的to have...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)。

She doesn't seem to like the idea. 她似乎不太喜欢这个想法。

They seemed not to know each other. 他们看起来好像互不认识。

4. seem + 分词

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

It seems like years since I last saw you. 自从上次我见到你似乎过去好多年了。

They seemed in high spirits. 他们似乎情绪高涨。

三、 seem常用于由as if / though引导的从句中。

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。

It seems to me that we have been neglecting our duty. 我感觉我们对职责有所疏忽。

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。

There seemed 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 there were 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.”。

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。
