seem在英語單詞中的用法歸納
一、seem常用于it作形式主語的結構，即It seems / seemed that..., 表示“看來……，似乎……”。
It seems that nobody knew what had happened. 似乎沒人知道發(fā)生了什么事。
It seems that he was late for the train. 看來他沒趕上火車。
注意：1)在這一句式中，?？墒∪hat。
2)在seem后間或可跟形容詞。
It seems impossible that he will be here tomorrow. 明天他來這兒似乎是不可能的。
二、seem可與形容詞、名詞、不定式(短語)、分詞及介詞短語搭配。
1. seem + 名詞
That seems a good idea. 那似乎是個好主意。
She seems a clever girl. 她似乎是個聰明的女孩。
2. seem + 形容詞
She seems quite happy today. 今天她似乎很高興。
3. seem + 不定式(短語)
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. 他似乎正在考慮某事。
Something seemed to be wrong with the train. 火車好像出了故障。
注意：1)不定式是to be并以名詞或形容詞作表語時，to be通?？梢允÷?。這樣就變成1，2的用法。
He seems (to be) a fool. 他好像是個傻子。
She seems (to be) quite unhappy. 她看起來很不高興。
2)seem后跟不定式時，要注意不定式所表示動作發(fā)生的時間，以此來確定不定式的時態(tài)。如3中的to have...為不定式的完成時。
3)seem的否定式可在不定式前直接加not或借助do的相應否定形式來表達(放在seem前)。
She doesn't seem to like the idea. 她似乎不太喜歡這個想法。
They seemed not to know each other. 他們看起來好像互不認識。
4. seem + 分詞
He seemed pleased at what I said. 聽了我的話，他似乎很高興。
The news seems exciting. 消息似乎很激動人心。
5. seem + 介詞短語
It seems like years since I last saw you. 自從上次我見到你似乎過去好多年了。
They seemed in high spirits. 他們似乎情緒高漲。
三、 seem常用于由as if / though引導的從句中。
It seems as if somebody is calling you. 好像有人在叫你。
It seems as though he were very stupid. 看來他似乎很笨。
注意：在as if / though引起的從句中，如果說的是非真實的情況，從句謂語用虛擬語氣，如上句he were very stupid。如果所述的情況實現(xiàn)的可能性較大，則從句的謂語常用陳述語氣。
四、 seem常用在“It seems / seemed to sb. (that)...”結構中，這種結構常用來表示“行為”的主體。
It seems to me that we have been neglecting our duty. 我感覺我們對職責有所疏忽。
It seems to me that they are right. 我感覺他們是對的。
五、用于There seems / seemed + to be + n. (主語)中。
There seemed to be no work for you to do now. 看來現(xiàn)在沒有什么工作需要你做了。
注意：1)在這一結構中，seem表示“似乎有;看來有”。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)這一結構的否定形式為“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. 在這個問題上似乎沒出現(xiàn)什么困難。
