初中階段的英語學(xué)習(xí)至關(guān)重要，各位小伙伴一定不要荒廢了大好時(shí)光。以下是小編整理的關(guān)于初中英語學(xué)習(xí):as if 引導(dǎo)什么狀語從句的資料，希望對(duì)你有所幫助！

as if 引導(dǎo)方式狀語從句。①當(dāng)說話者認(rèn)為句子所述的是真實(shí)的或極有可能發(fā)生或存在的事實(shí)時(shí)，as if從句用陳述語氣。②當(dāng)說話人認(rèn)為句子所述的是不真實(shí)的或極少有可能發(fā)生或存在的情況時(shí)，as if從句用虛擬語氣。表示與現(xiàn)在事實(shí)相反，謂語動(dòng)詞用一般過去式。

as if 用法歸納

1.as if 從句的作用

as if一般可由as though來代替?？稍趌ook, seem等系動(dòng)詞后引導(dǎo)表語從句。如:

He looked as if / though he was ill. 他看起來好像生病了。

It seems as if it is going to rain.

看來好像要下雨了。

它還可引導(dǎo)方式狀語從句。如:

I remember the whole thing as if / though it happened yesterday.

我記得整個(gè)事情,就好像它是發(fā)生在昨天一樣。

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

那個(gè)小孩跟我們講話就像個(gè)大人一樣。

2.as if 從句的語氣及時(shí)態(tài)

①當(dāng)說話者認(rèn)為句子所述的是真實(shí)的或極有可能發(fā)生或存在的事實(shí)時(shí),as if從句用陳述語氣。如:

It sounds as if it is raining.

聽起來像在下雨。

He talks as if he is drunk.

從他說話的樣子來看他是醉了。

②當(dāng)說話人認(rèn)為句子所述的是不真實(shí)的或極少有可能發(fā)生或存在的情況時(shí),as if從句用虛擬語氣。

表示與現(xiàn)在事實(shí)相反,謂語動(dòng)詞用一般過去式。如:

You look as if you didn’t care.

你看上去好像并不在乎。

He talked as if he knew what had happened.

他說話的樣子,好像他知道發(fā)生了什么事情。

表示與過去或與談話時(shí)間為止發(fā)生的事實(shí)相反,謂語動(dòng)詞用“had +過去分詞”。如:

He talked about the Great Wall as if he had been there before.

他說起長城來好像他以前去過那里。

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

那女孩傾聽著,一動(dòng)也不動(dòng),像已經(jīng)變成了石頭。

表示與將來事實(shí)相反,謂語動(dòng)詞用“would / could / might + 動(dòng)詞原形”。如:

He opened his mouth as if he would say something.

他張開嘴好像要說什么。

It looks as if it might snow.

看來好像要下雪了。

3.as if從句中的省略

如果as if 引導(dǎo)的從句是“主語+系動(dòng)詞”結(jié)構(gòu),可省略主語和系動(dòng)詞等成份,這樣as if 后就只剩下名詞、不定式、形容詞(短語)或動(dòng)詞-ing形式等。

He acts as if (he was) a fool.

他做事像個(gè)傻子。

He paused as if (he was going) to let the sad memory pass.

他停了下來,就好像要把悲傷的記憶抹去。

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

女孩匆忙離開房間,好像生氣的樣子。

From time to time, Jason turned round as if (he was) searching for someone.

賈森不時(shí)地轉(zhuǎn)過身來,好象在找人。
