19.1 地點狀語從句

地點狀語從句通常由where, wherever 引導。

Wherever I am I will be thinking of you.

不管我在哪裡我都會想到你。

19.2 方式狀語從句

方式狀語從句通常由as, (just) as…so…, as if, as though引導。

1) as, (just) as…so…引導的方式狀語從句通常位於主句後,但在(just) as…so…結構中位於句首,這時as從句帶有比喻的含義,意思是"正如…","就像",多用於正式文體,例如:

 Always do to the others as you would be done by.

 你希望人家怎樣待你,你就要怎樣待人。

 As water is to fish, so air is to man.

 我們離不開空氣,猶如魚兒離不開水。

 Just as we sweep our rooms, so we should sweep backward ideas from our minds.

 正如打掃房屋一樣,我們也要掃除我們頭腦中落後的東西。

2) as if, as though

兩者的意義和用法相同,引出的狀語從句謂語多用虛擬語氣,表示與事實相反,有時也用陳述語氣,表示所說情況是事實或實現的可能性較大。漢譯常作"彷彿……似的","好像……似的",例如:

 They completely ignore these facts as if (as though) they never existed.

 他們完全忽略了這些事實,就彷彿它不存在似的。(與事實相反,謂語用虛擬語氣。)

 He looks as if (as though) he had been hit by lighting.

 他那樣子就像被雷擊了似的。(與事實相反,謂語用虛擬語氣。)

 It looks as if the weather may pick up very soon.

看來天氣很快就會好起來。(實現的可能性較大,謂語用陳述語氣。)

 說明:as if / as though也可以引導一個分詞短語、不定式短語或無動詞短語,例如:

 He stared at me as if seeing me for first time.

他目不轉睛地看著我,就像第一次看見我似的。

 He cleared his throat as if to say something.

他清了清嗓子,像要說什麼似的。

 The waves dashed on the rocks as if in anger.

波濤衝擊著岩石,好像很憤怒。

19.3 原因狀語從句

比較:because, since, as和for

1) because語勢最強,用來說明人所不知的原因,回答why提出的問題。當原因是顯而易見的或已為人們所知,就用as或 since。

I didn't go, because I was afraid.

Since /As the weather is so bad, we have to delay our journey.

2) 由because引導的從句如果放在句末,且前面有逗 號,則可以用for來代替。但如果不是說明直接原因,而是多種情況加以推斷,就只能用for。

He is absent today, because / for he is ill.

He must be ill, for he is absent today.
