XDF 语法题:
Developing nations in various parts of the world have amassed $700 billion in debts; at stake , [U]should a significant number of these debts be repudiated, is the solevency of some of the world's largest multinational banks.[/U]
答案选:A
后两个分句和第一个分句是什么关系? 我怎么不明白后两个分句是什么意思呢?
should .....be repudiated, is ......是什么语法结构呀? [em08]
