答案與詳解

1．A．條件句表示與現在事實相反的虛擬。

2．B．條件句表示與過去事實的虛擬。

3．A．條件句表示與未來事實的虛擬。

4．B．條件句表示與未來事實的相反。

5．C．條件句表示與現在事實的虛擬。

6．D．條件句表示與現在事實的虛擬。

7．B．這個句子中含有一個省略if，把助動詞提前到主語they之前的虛擬條件句，該條件句表示對過去情況的假設，而主句中by the time they were finished 表明主句也應該是對過去發生的情況的假設，因而應該選（B）would have lost為正確答案。

8．（D）這道題目是一個混合虛擬語氣的句子。條件句省略了if，把助詞had提前到主語前面，表示對過去情況的假設，而主句中now表明了對現在情況的假設，所以應選would(should, could, might)+動詞原形這種表達形式。四個選項中只有（D）是正確表達形式，故為正確答案。

9．（D）until recently，因此（D）是正確答案，而主句是隱含的對現在情況的假設，該句是一個混合虛擬條件句。

10．（B）假設的情況有時不是用一個條件句表示，而是隱含在一個由介詞如but for、but that、without, 由連詞but、副詞otherwise 、比較級、形容詞、獨立主格等表示的上下文中。本句主句表示對過去情況的假設，但事實上由于英語考試而沒有去成，即若不是因為英語考試，我本可以去聽音樂會，所以應選But for為正確答案。

11．（C）題目中的第一句話表示的是現在真實的情況，而第二句話中所要表達的是應該做但事實上沒有做的事，這種情況導致第一句話中真實情況的發生，故If only條件句假設的是過去一種情況，因此應該用had +過去分詞，所以正確答案是（C）。

12．D．注意主句now表示現在的時間狀語，所以主句是對現在虛擬，從句是對過去虛擬。

13．A．從句對過去的虛擬。

14．B．從句表示虛擬，而主句是事實。

17．（D）本道題目的前半句話是對過去情況的一種假設，但事實上并沒有發生，而事實上沒有發生的真實原因是句子的后半部分由but引導的轉折句所表述的真實。因而but所引導的句子中應該用表示志過去事實相符合的表陳述的時態，即一般過去時。

18．（B）此題要求在if從句中選擇適當的動詞形式，以主句中的動詞apologize(抱歉)來看，if從句中表達的內容應該是過去做的事，因此可以排除（A），因為（A）是現在時。（C）中should+have+過去分詞結構表示本來應該做卻沒有做的事，在此不合題意。（D）選項中的might+have+過去分詞表示對過去發生的事情很不肯定的猜測，它表達的內容還不能成為事實，所以藉此道歉真是不知從何說起，因此此處也不合題意。（B）had offended表示當時已經發生了的動作。這是復雜條件句：apologize 是現在，而條件句是表示對過去假設的條件句。

19．（A）該句也是一個復雜條件句（或稱作混合虛擬條件句）。條件句表示對過去情況的假設，而主句表示對現在情況的假設，但事實上卻與此相反，所以正確答案應該是（A）。

20．（A）as if引導的從句要求用虛擬語氣，表示同時或將來的情況，動詞要用過去式（be動詞用were）或would(could等)+動詞原形，本句話中指的是當時的情況，所以要用過去式，故（A）是正確答案。

21．D． 22．D． 23．C． 24．A． 25．D．

26．（B）had not occurred表示對過去的虛擬，條件句中要用過去完成式，主句中要用should(would, could, might)+動詞原形的過去分詞。

27．（B）had hoped是常見的要求其后的賓語從句用虛擬語氣的句型,虛擬語氣would+動詞原形。

28．（C）表示對過去情況的假設，主句動詞形式為would(should, could, might)+have+過去分詞，條件句為過去完成式，if可以省略，但要把had提前主語前面。（B），（D）的表達不符合英語表達習慣，所以（C）是正確答案。

29．（A）suggest后面的從句要用虛擬語氣形式，其形式為should（可以省略）+動詞原形。

30．A．表示與現在相反的虛擬。

31．A．as though引導的與過去相反的虛擬。

32．D．felt是過去式，所以該句是由as though引導的與過去相反的虛擬。

33．D．as if引導的與現在事實相反的虛擬。

34．A．as if引導的與過去相反的虛擬。

35．C．

36．（D）would rather后接從句要求用虛擬語氣，形式為過去式，表示對現在或將來的假設，或為過去完成式表示對過去的情況的假設。

37．（C）who引導的定語從句中的現在完成時表示動作業已發生，所以主句中表示的虛擬是針對已經發生了的行為，所以應該用過去完成式表示對過去的虛擬。

38．（B）

39．（C）這是一人含蓄虛擬條件句，通過介詞短語without,表示潛在的一種假設，而主句中的情況也早已經發生，所以是對過去情況的一種假設，因此用would not have been achieved這一形式。

40．（D）連so that引導的從句中要求用虛擬語氣，表示一種假設，形式為might+動詞原形。

41．（B）It is time that是一種要求從句用虛擬語氣的常見句型。虛擬語氣形式為動詞的過去式。

42．（C）

43．（C）otherwise用來表示一種含蓄的虛擬假設，因為是對過去(yesterday)的情況的假設，所以應該用would have come形式。

44．（B）所給的四個選項中沒有一個表示對未來的情況的虛擬的形式should+動詞原形，或是were to do，因此可以斷定if引導的條件句在這里最真實的條件句，用一般現在時表示一般將來時，故（B）是正確答案。

45．（A）這是一個混合虛擬語氣的句子，if條件句表示的是對過去情況的假設，而主句是對現在（now）的情況的假設，故用would tell形式。

46．C． 47．C． 48．C．

49．B．would rather引導的虛擬語氣其謂語用過去式。

50．D．would as soon引導的虛擬語氣，其謂語動詞也用過去式.

51．B． 52．B． 53．B． 54．B．

55．C．注意單詞otherwise引導虛擬語氣。

56．C．同上。

57．A．注意詞組for fear that

58．A．注意without

59．C． 60．C． 61．D． 62．B． 64．A． 65．D．
