When we hear of dangerous diseases, cancer and heart disease are often what first comes to mind. Recently, a virus (病毒) called Ebola has reappeared in Guinea (a country in West Africa), killing 62 people so far. It leads to viral hemorrhagic fever, which is characterized by high fever and internal bleeding etc, Ebola can kill 90% of those infected, especially in underdeveloped societies like those in Africa.
Ebola is named after the Ebola River, where it was first discovered in 1976.There are five different types of the Ebola virus, each named after where they first happened: Sudan, Ivory Coast, Restoon, Bundibugyo, and Zaire.The deadliest of the five, Zaire, was responsible for the 2012 outbreak, and is believed to be attacking Guinea.
Ebola is naturally found in fruit bats (果蝠), which pass on the virus to other animals by biting or sucking on (吮吸) their blood.Humans who are suffering from the Ebola infection might have touched the bodily fluids (液体) of the infected animals.Once infected, a human becomes a carrier of the deadly virus.
Since we live in an interconnected world, where the situation in one country can affect us all, the influences of Ebola are huge: damaging trade relations, affecting foreign visitors, and weakening entire countries.Already the Guinea virus is spreading fast with a few cases spotted in Conakry — the capital of Guinea, far away from the origin of the virus.It is feared that the disease may have already reached neighboring Liberia and Sierra Leone, too.
Unfortunately, there are no disease-specific treatments for Ebola.Healthcare workers only supply the infected people with water to keep them in good condition.Since there have been many cases of nurses catching the disease from patients, they are forced to wear strict protective clothes, and in some cases, not even allowed to get close to the affected.The fact that there is no cure for the Ebola virus is what makes the outbreak a challenging one to control.
1.The news of Ebola in Guinea is mentioned to ________.
A. make a brief summary
B. introduce the topic of the text
C. compare Ebola with cancer
D. show the latest study of viruses
2.What can we learn about Ebola?
A. It is a newly discovered virus.
B. It is the most dangerous virus in the world.
C. It was named after where it first happened.
D. It could cause immediate death for anyone infected.
3.What is mainly described in Paragraph 3?
A. What the Ebola virus is.
B. The influences of Ebola.
C. The treatments for Ebola.
D. How the Ebola virus spreads.
4.Which of the following does the author probably agree with?
A. Ebola is a highly infectious virus.
B. Ebola is now very common in Guinea.
C. Those with a fever must be infected by Ebola.
D. Females are more easily to be infected by Ebola.

My friend had mentioned the other day that her father had a lot of children's toys he was looking to give away.She knew I have a three-year-old daughter so she thought of me first.I told her I would love it if I could get some nice things for my daughter,which I wouldn't otherwise have been able to afford.

When I met her father,he began to explain he was too poor once and that he would hate to throw away things that can be very useful.

Before he showed me what he was giving away,I thought the toys would be mostly lego's(乐高积木) or things like that.When he was showing me around I saw a bed,a slide,a kitchen set and many other things that just blew my mind.He told me to write a list of everything my daughter could use and as my eyes were wide,he told me not to feel guilty.He said I was helping him by getting rid of the stuff.

As I was looking around I did feel guilty,but I tried to remain more grateful than guilty.Every time I tried to thank him for giving me and my daughter all this wonderful stuff he would thank me right back.I wanted to believe that he was just thanking me so that I wouldn't feel so guilty but in reality I believe that he was as grateful as I was that these toys would be put to good use.

In the eyes of charity,it makes sense to feel grateful,but guilt is just as normal.I know that we could have lived without a slide,which is why I do feel guilty,but I am grateful all the same because my daughter really does enjoy all these nice things!
