以下是引用lb1900在2006-5-23 16:28:00的发言：5． Developing nations in various parts of the world have amassed $700 billion in debts; at stake, should a significant number of these debts be repudiated, is the solvency of some of the worlds largest multinational banks.
(A) should a significant number of these debts be repudiated, is
(B) should a significant number of these debts be repudiated, are
(C) should they repudiate a significant number of these debts, are
(D) if there is a repudiation of a significant number of these debts,would be
(E) if a significant number of these debts will be repudiated, is 答案是a. 但从句虚拟，主句怎么可以用一般现在时？ my two cents: 1. should a significant number of these debes be repudiated. = if a significant number of these debts should be repudiated. 类似的还有 were, had 的倒装并省略if, in other words, Leaving out "if": formal inversion - structures: In formal styles, "if" can be droppped and an auxiliary verb put before the subject. this happens with "were, had and should; very rarely with other auxiliary verbs. 2. 后半句就是一般现在时呀 The pattern if...should suggest that something is unlikely, or not particularly probable, by using 'should (not would)' in the if -clause. If you should run into Peter, tell him he owes me a letter. 3. More details for 1: Should you change your mind, ..... = If you should change...) Were she my daughter, .... ( = If she were my daughter...) Had I realized what yo intended, .... ( = If I had realized....) 手都达累了, 希望说清楚了.
