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，?？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(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。
