英语时态问题

英语时态问题最后一题，我知道要倒装，可是为什么这里用过去时啊?还有顺便问一下，这句子的主句是什么，从句是什么，我老是分不清主句和从句，就很烦

Answer 1

1. Not
   until Dec. 2003 _____ caught by the US soldiers,

and it was a great victory for
the USA.

A.
was Saddam Hussein              B. Saddam
Hussein was

C.
had Saddam Hussein been      D. Saddam
Hussein had been

选A。 not until位于句首时，句子要部分倒装。

而时间状语Dec. 2003暗示了要用一般过去时，故此只能选A。

Answer 2

用过去时是因为until Dec. 2003 具体时间状语。这句话是个简单句：Saddam Hussein wasn’t caught by the U. S. soldiers until Dec. 2003.

追答

由于倒装，否定词
前移，成为Not
until ..., was ... caught by the U.S. soldiers .

如还有疑问，欢迎追问，有问必答！
