答案

参考答案:E

解析:HPV的传播主要通过直接接触感染者的病损部位或间接接触被病毒污染的物品。生殖器感染主要是性接触引起。新生儿可在通过产道时受感染。病毒感染仅停留于局部皮肤和黏膜中,不产生病毒血症。HPV除尖锐湿疣外,HPV-16、18型与子宫颈癌的发生密切相关。

When Kathy and Victor reached the edge of the grassland, flames(火焰)were shooting more than five meters into the air.

Kathy couldn’t believe what she was seeing. One glance told her they needed medical attention immediately. She questioned Justin, “ Is there anyone in the plane?”

“Where are you able to radio for help?”

“There was no time.”
