问题
选择题
Anyone, once _______ positive for H7N9 flu virus, will receive free medical treatment from our government.
A.to be tested
B.being tested
C.tested
D.to test
答案
答案:C
题目分析:考查状语从句的省略:句意:任何人,一旦被检测出H7N9呈阳性,就可以得到政府免费的医疗护理。英语中当主从句的主语一致的时候,可以省略从句的主语和be动词,所以完整的从句应该是once anyone is tested…..,这时可以省略anyone is,就剩下tested,所以选C。
