Question

【题目】【改编】Nowadays, some people are suffering from Ebola, which if not , will threaten their lives.

A. having treated properly

B. to treat properly

C. properly treating

D. properly treated

Answer 1

【答案】D

【解析】选D。考查非谓语动词。句意: 现在, 一些人感染上了埃博拉病毒, 这种病如果不能正确治疗, 就会威胁他们的生命。if not properly treated相当于if it is not treated properly。treat与其逻辑主语H7N9之间是被动关系。副词应该在过去分词之前，修饰动词。
