【简答题】
What’s ebola? Ebola is a virus. A virus is a very small thing. A bit of 1 and a few proteins 2 . It has no ability to do anything by itself what so ever and can only survive and 3 by infecting cells. To avoid this we have the immune system. How does it attack people? But when Ebola strikes, it directly attacks the immune system. In a nutshell, it takes over the cell, 4 the cell’s protective mechanisms and 5 it. The cell now becomes a virus production machine and uses its resources to build Ebola viruses. So the immune system is seriously 6 and unable to react while the virus rapidly multiplies. We're talking billions. Another area of the body Ebola attacks is the 7 . The virus finds it very easy to enter the liver and it quickly starts killing loads of liver cells and causing 8 and more 9 . Why no need to panic? Currently 10 infected die from Ebola. Wow! Ok. Ebola is nasty. So it’s time to panic, right? No, not even close. The 11 of Ebola gets paper sold and , YouTube video shared, so everybody is talking about Ebola. But currently the only way to get infected by Ebola is to come into contact with the 12 from the person who shows the symptoms all from 13 . So just don’t do that. Ebola has killed 5,000 people since June 2014. The 14 kills up to 500,000 people each year. 15 kills up to one million each year. 3,000 people every single day, ten children since this video started. So even if Ebola is terrible and scary, don’t let yourself be scared.
