It seems that / as if ...用法舉例辨析

　　此句型實質上是“主+系+表”結構。其中it是人稱代詞，并無實意，指的是某種情況，seems為系動詞，that / as if 引導表語從句。

　　一、It seems that …表示“看起來……”。

　　強調根據(jù)一定的事實所得出的一種接近于實際情況的判斷，可以說表示事實。(可以轉換成“名詞或代詞 + seem +動詞不定式”句型，其意不變，如果動詞不定式為to be + 形容詞時，to be往往省略。)

　　It seems that it is more difficult for women to get to the top of the  company. 婦女似乎更難提升到公司的最高職位。

　　It seems that no one knows what has happened in the park. (No one seems to know what has happened in the park.) 似乎沒有人知道在公園里發(fā)生了什么事。

　　It seems to me that he has known everything. (He seems to have known everything) 在我看來他似乎什么事都知道了。

　　It seems that he likes his new job. 他看起來很喜歡他的新工作。

　　It seems that they don't like the idea. 他們似乎不喜歡這個主意。

　　It seems that he is lying.看來他在撒謊。

　　二、It seems as if ...也表示“看起來……，似乎……”。

　　使用該句型表示可能：若從句表示的是很可能實現(xiàn)的事情，從句謂語用陳述語氣;若從句表示的是與事實相反的假設或實現(xiàn)的可能性很小的事情時，則從句謂語要用虛擬語氣。

　　1、從句的謂語動詞常用虛擬語氣來表示所設想的事情不真實或不可能發(fā)生/存在。

　　It seems as if she had read this novel.看來她好像看過這本小說。

　　It seems as if it were autumn. 現(xiàn)在仿佛是秋天似的。

　　It seems as if it were spring already. 似乎春天已經來了。

　　It seems as if he were in a dream.看來他像是在做夢。

　　It seemed as if the good man were trying to teach us all he knew at this last lesson.這個好心人仿佛要在最后這一堂課上把他的全部知識教給我們。

　　2、如果可能性很大則用陳述語氣，或者句中的情況可能發(fā)生或可能被設想為真實，則仍然用陳述語氣。

　　It seems as if our team is going to win.看來我們隊要勝了。

　　It seems as if he has learned by heart a speech written by someone else.看來他像是背了一篇由別人寫的演講稿。

　　It seems that it is going to rain. 仿佛天要下雨。

　　It seems as if our team is going to win. 看來我們隊要勝了。

　　3、as if還可用于其它動詞之后或省略句中。

　　(as if引導的從句是“主語+系動詞”結構，可省略主語和系動詞，只剩下名詞、不定式、形容詞(短語)、介詞短語或分詞。)

　　She looks as if she were ten years younger. 她看起來好像年輕了十歲。
