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。
2. Be careful with such things. If you _____, you’ll drop them.
A. don’t B. aren’t C. won’t D. do
选B。本题考查学生运用省略语法的做题能力。 完整的句子为：If you aren’t (careful)，you’ll drop them. 另外，条件状语从句用现在时表将来，所以排除了won’t。
