The experiments in giving the virus to animals proved that this type of influenza was easy to catch ______.
A．and could possibly cause death
B．and had rather mild effects
C．but was not deadly
D．and did not have the usual signs
参考答案
正确答案：C
解析：词义题型见第四段第三句：These experiments proved that the new virus was easy to catch，but that it was not a killer．Scientists like the general public，call it simply Asian flu. (这些试验证实这种新的病毒很易感染，但并不致命。)在此须弄懂not a killer之意， “不是杀手”即“并不致命”，因此C为答案。
