與將來事實相反的虛擬語氣

 

請看下面的題目:

If we __________ 200 years oldwe __________ everything.

A. were to becould change                                                 B. had beenchanged

C. werewould have changed                                    D. should bechanged

此題應選A。該題考查與將來事實相反的虛擬語氣,此時的主句謂語通常用would(shouldcouldmight)+動詞原形,而從句謂語可能有以下幾種情況:

1. 從句謂語用過去式:

If your father knew thishe would be angry. 要是你父親知道了,他會生氣的。

If it rained tomorrowthe sports meet would beput off. 要是明天下雨,運動會就推遲。

2. 從句謂語用should+動詞原形(通常指可能性極小的事情,一般譯為“萬一”)

If it should rainthe crops would be saved. 要是有雨,這莊稼還有救。

此類句型的主句謂語有時可以用祈使句甚至將來時態:

If it should rain tomorrowdon’t expect me. 萬一明天下雨,就不要等我了。

If I should be free tomorrowI will come. 萬一我明天有空,我就來。

3. 從句謂語用were to+動詞原形 (通常指可能性極小可或近乎不可能,有時指出乎意料)

If the sun were to rise in the westmy love for you would not change. 即使太陽從西邊出,我對你的愛也不會變。
