as if 的用法

as if 從句的作用

1．引導表語從句， 常與as,look,seem,feel,taste,smell,sound等系動詞連用。

如：

She looks as if she were ten years younger．

她看起來好像年輕了十歲。

It seems as if our team is going to win．

看來我們隊要勝了。

It looks as if a tornado swept through your room.

好像有龍捲風席捲過你的房間。

It looks as if they're looking for something.

他們看起來好像在找什麼東西。

2. 引導方式狀語從句，表示“事情是怎麼做的”或“一個人或事物是什麼樣的”。

如：

She loves the boy as if she were his mother．

她愛這男孩，就好像她是他的媽媽一樣。

The child talked to us as if he were a grown-up．

那孩子跟我們談起話來，像個成年人似的。

She spoke to me as if she knew me.

她和我説話的神情，好像她早就認識我。

You answered the question as if you did not know this rule.

你回答的問題好像不知道這個規則似的。

as if 還可用於省略句中

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

如：

He acts as if （he were） a fool．

他做事像個傻子。

Tom raised his hands as if （he was going） to say something．

湯姆舉起手好像要説什麼。

She left the room hurriedly as if （she was）angry．

她匆忙離開房間好像生氣的樣子。

1． as if 從句用陳述語氣的情況。 當説話者認為句子所述的是真實的或極有可能發生或存在的事實時。

如：

It sounds as if it is raining．

聽起來像是在下雨。

He talks as if he is drunk．

從他談話的樣子來看他是醉了。

The boss speaks aloud as if he is angry.

老闆説話聲音很高，好像他真的生氣了。

He is a happy-go-luck man as if he has no worries and cares in the world.

他是一個很快樂的人，似乎無憂無慮。

2．as if 從句用虛擬語氣的情況。 當説話人認為句子所述的是不真實的或極少有可能發生或存在的情況時。從句虛擬語氣動詞時態的形式如下：

（1）如果從句表示與現在事實相反，謂語動詞用一般過去時。

如：

You look as if you didn’ t care．

你看上去好像並不在乎。

He talks as if he knew where she was．

他説話的樣子，好像他知道她在哪裏似的。

When a pencil is partly in a glass of water,it looks as if it were broken.

當一支鉛筆部分地放在水中時，它看上去像是折斷了。

（2）從句表示與過去事實相反，謂語動詞用“had+過去分詞”。

如：

He talks about Rome as if he had been there before．

他説起羅馬來好像他以前去過羅馬似的。

The girl listened as if she had been turned to stone．

那女孩傾聽着，一動也不動，像已經變成了石頭似的。

Everythings in my childhood crowded in my mind as if they had just happened.

童年發生的一切都擠在我的腦海，彷彿就像剛剛發生的一樣。

（3）從句表示與將來事實相反，謂語動詞用“would/could/might+動詞原形”。

如：

He opened his mouth as if he would say something．

他張開嘴好像要説什麼。

It looks as if it might snow．

看來好像要下雪了。

(4)as if 後面可以接陳述語氣和虛擬語氣，如果句子的情況是真實的，那麼只要保持時態一致即可，如果後面接的並非真實情況，則要按照虛擬語氣規則把句子形式改變（簡單説就是時態倒退原則）。

(5) as if 在俚語中能表示反諷，單獨使用時表達為“想得美”“好像真會發生似的”等意思，可以把其想成是“as if it would happen”的縮寫，功能類似"like"，舉例：As if / Like you are going to do the dishes；"like"不能獨立成句，但as if 能（完整句子為：as if that/it is true.），例子：甲：She said she would help me with the project. 乙：As if！

(6)談論過去情形的動詞形式有以下幾種：

a)過去式，表示過去的狀態，如：

He looked at me as if I were mad. 他那樣看我，好像我是個瘋子。

He stood there looking at the train and laughing, as if to miss a train was the best joke in the world.他站在那裏，望着火車哈哈大笑，好像誤了火車是天底下最開心的事兒似的。

Mr. Coleman always talked as if he knew everything.

但是，如果狀態動詞帶有持續時間狀語，則用過去完成時：

They talked as if they had been friends for years. (高二冊，第95頁)

Now it is as though she had known Millie for years. (《現代英語用法詞典》)

情態動詞亦用過去時：

She felt as though she could hardly endure such a life.她覺得簡直無法忍受這樣的生活。

b)過去完成時，表示過去的動作先於主句動詞而發生或完成，如：

It was as if he had lost his last friend. “I remember,” she tells her children now, “how wild his white

hair looked——as if it had been electrified.”（高二冊，第91頁）

必須注意的時，在指過去的動作時，即使主句是現在時，as if 從句中的動詞也要用過去完成時：

You look as if you’d seen a ghost. 你好像是見了鬼似的。

He talks about Rome as though he had been there himself.他講起羅馬的情況來就好像他親自到過那裏似的。

c)過去進行時，表示動作正在進行：

He heard a noise, as if someone was brea ^[1]  thing.（高一冊，第211頁）

He ran as if ghosts were chasing him.

I felt as if the ground were slipping beneath my feet. 我感到大地彷彿在腳下滑動。

d)過去將來時，表示將要發生的事態：

It looked as if it was going to snow. （高一冊，第127頁）

He opened his lips as if he would say something to you.

It seems as if it is raining. 外面看起來像是下雨了。（確實是下雨了）

It seems as if it were raining. 外面看起來好像下雨一樣。（虛擬語氣，其實並沒有下雨）
