seem在英語(yǔ)單詞中的用法歸納
seem作系動(dòng)詞時(shí)有“似乎”或“好像”之意。seem表示對(duì)某事物做出判斷時(shí)雖有一定的根據(jù)，但仍然有所懷疑，著重于說(shuō)話人的主觀感覺(jué)。下面是小編整理的一些關(guān)于seem的用法， 希望讓大家更好地認(rèn)識(shí)seem這個(gè)單詞，提高英語(yǔ)水平。
seem在英語(yǔ)單詞中的用法歸納
一、seem常用于it作形式主語(yǔ)的結(jié)構(gòu)，即It seems / seemed that..., 表示“看來(lái)……，似乎……”。
It seems that nobody knew what had happened. 似乎沒(méi)人知道發(fā)生了什么事。
It seems that he was late for the train. 看來(lái)他沒(méi)趕上火車。
注意：1)在這一句式中，常可省去that。
2)在seem后間或可跟形容詞。
It seems impossible that he will be here tomorrow. 明天他來(lái)這兒似乎是不可能的。
二、seem可與形容詞、名詞、不定式(短語(yǔ))、分詞及介詞短語(yǔ)搭配。
1. seem + 名詞
That seems a good idea. 那似乎是個(gè)好主意。
She seems a clever girl. 她似乎是個(gè)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(yǔ))
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(yǔ)時(shí)，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(gè)傻子。
She seems (to be) quite unhappy. 她看起來(lái)很不高興。
2)seem后跟不定式時(shí)，要注意不定式所表示動(dòng)作發(fā)生的時(shí)間，以此來(lái)確定不定式的時(shí)態(tài)。如3中的to have...為不定式的完成時(shí)。
3)seem的否定式可在不定式前直接加not或借助do的相應(yīng)否定形式來(lái)表達(dá)(放在seem前)。
She doesn't seem to like the idea. 她似乎不太喜歡這個(gè)想法。
They seemed not to know each other. 他們看起來(lái)好像互不認(rèn)識(shí)。
4. seem + 分詞
He seemed pleased at what I said. 聽(tīng)了我的話，他似乎很高興。
The news seems exciting. 消息似乎很激動(dòng)人心。
5. seem + 介詞短語(yǔ)
It seems like years since I last saw you. 自從上次我見(jiàn)到你似乎過(guò)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(dǎo)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(lái)他似乎很笨。
注意：在as if / though引起的從句中，如果說(shuō)的是非真實(shí)的情況，從句謂語(yǔ)用虛擬語(yǔ)氣，如上句he were very stupid。如果所述的情況實(shí)現(xiàn)的可能性較大，則從句的謂語(yǔ)常用陳述語(yǔ)氣。
四、 seem常用在“It seems / seemed to sb. (that)...”結(jié)構(gòu)中，這種結(jié)構(gòu)常用來(lái)表示“行為”的主體。
It seems to me that we have been neglecting our duty. 我感覺(jué)我們對(duì)職責(zé)有所疏忽。
It seems to me that they are right. 我感覺(jué)他們是對(duì)的。
五、用于There seems / seemed + to be + n. (主語(yǔ))中。
There seemed to be no work for you to do now. 看來(lái)現(xiàn)在沒(méi)有什么工作需要你做了。
注意：1)在這一結(jié)構(gòu)中，seem表示“似乎有;看來(lái)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(jié)構(gòu)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(gè)問(wèn)題上似乎沒(méi)出現(xiàn)什么困難。
