Question

【题目】The virus Ebola is reported ______ over 3,000 lives in 5 countries of West Africa by now.

A. taking B. having taken

C. to take D. to have taken

Answer 1

【答案】D

【解析】试题分析：考查时态。根据句意可知埃博拉病毒是已经发生了的事，并且是被报道，以及句尾时间状语by now到现在，所以要用现在完成时，sth.be reported to表示某事被报道...，故采用不定式。句意：据报道，到现在为止埃博拉病毒已经导致西非5个国家超过3000人死亡了，故选D。
