【题目】根据短文内容, 从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Ebola is a dangerous virus that can cause people to get very sick and even die. The virus is causing the biggest problems in western Africa, where it has spread quickly. But it can get worse and cause life-threatening symptoms(症状), such as bleeding and trouble breathing.
Ebola does not spread like colds or the flu because it does not float through the air. Ebola also doesn't spread through food or water, like some other viruses. Instead, Ebola spreads when someone touches the body fluids(液体) of a sick person.
An outbreak is when many people are getting sick with the same illness around the same time. You may have heard of a flu outbreak, which is when lots of people get sick from the same types of flu virus. When an outbreak happens because of a virus, more people could get sick because there is a lot of that virus around.

【解析】本文介绍了埃博拉病毒爆发的相关情况,以及人们该如何保护自己免遭病毒的侵袭。
(1)E 前文提到埃博拉是一种致命的病毒,下文提到其症状,所以此处应该说明埃博拉的症状的情况,故应填入E项。
(2)A 下文说明埃博拉病毒的传播途径,小标题概括这部分内容,故应填入A项“人如何会感染埃博拉病毒?”。
(3)F 下文说明埃博拉病毒的爆发情况,因此小标题应该是“病毒爆发是什么情况?”故应填F项。
