问题补充：

A new virus related to SARS is reported at least one person in China last week.

A. to kill

B. to be killing

C. to have killed

D. kill

答案：

A. to kill

B. to be killing

(答案→)C. to have killed

D. kill

解析：考查句型结构sb/sth is reported to do及不定式的时态。根据句型结构，可排除D项，再根据时间状语last week说明kill动作发生在report之前，故使用不定式的完成式，选C。句意：据报道，上周一个与SARS有关的病毒至少导致了中国一人死亡。
