seem在英語單詞中的用法歸納

　　seem作系動詞時有“似乎”或“好像”之意。seem表示對某事物做出判斷時雖有一定的根據(jù)，但仍然有所懷疑，著重于說話人的主觀感覺。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seem這個單詞，提高英語水平。

　　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(jié)構(gòu)，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(yīng)否定形式來表達(dá)(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(rèn)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(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(shí)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(shí)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(jié)構(gòu)中，這種結(jié)構(gòu)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(zé)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(jié)構(gòu)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(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. 在這個問題上似乎沒出現(xiàn)什么困難。
