The current Ebola (埃博拉病毒)outbreak in western and central Africa has infected at least 3,069 people, including 1,552 dead, making it the largest outbreak in history. Ebola is a deadly virus-about 60 percent of people infected with it have died.

How is Ebola doing its harm?

When a person becomes infected with Ebola, the virus damages the body’s immune (免疫的)cells, which defend against infection, said a researcher at Lancaster University. But if a person’s immune system can stand up to this attack, then he is more likely to survive the disease.

The patients that survive it best are those who don’t get such a bad disadvantage in immune system. But if the body isn’t able to get rid of this attack, then the immune system becomes less able to regulate(调节) itself. This means the immune system is more likely to run out of control, leading to a drop in blood pressure, multi-organ failure and eventually death.

What are the common symptoms of the disease?

Fever. Headache. Joint and muscle aches. Weakness. Diarrhea. Vomiting. Stomach pain. Lack of appetite. Chills. Rash. Redness in the eyes. Hiccups. Cough. Sore throat. Chest pain. Difficult breathing or swallowing. Bleeding inside and outside of the body.

How to prevent the spread of Ebola?

Ebola can be spread primarily via direct contact with patients, specifically the blood and fluids of an infected patient.

We should avoid contact with infected patients and objects such as clothing, bedding, and needles used by them. Avoid areas where infections have been reported. For now, the disease has only been confirmed in central and West Africa, four cases in America and Europe. Avoid eating wild-caught bush meat. Researchers have suspected that the disease came to humans via animals, probably through the meat of primates(灵长类). If you’re in an area where the disease has been reported, avoid purchasing, eating, or handling wild game to stay on the safe side.

Wear protective medical clothing if you’re around infected patients. Extreme caution is necessary. Hospital workers must use masks, gloves, goggles, and gowns, which needed to be worn at all times if you’re around infected patients.

How Do People Survive Ebola?

Doctors don’t know for certain who will survive Ebola, and there is no specific treatment or cure for the disease. Although in the minority, some people do recover from infection.

Our suggestions include:

Maintain your electrolytes(电解质) and body liquid. Sports drinks can be used. Monitor your blood pressure and control it if necessary. Dropping blood pressure may be a serious sign of infection. Breathe in an oxygen-rich environment. Quickly address any symptoms of infection. Be honest about when and where you’re feeling pain.

Buy One Give One

Buy One Give One (B1G1) is a Singapore-based business and non-profit organization with a job to create a world full of giving. We help businesses around the world give back in meaningful ways so that they can create measurable and long-lasting influence. Since 2007, we have worked with more than 1,600 businesses creating more than 88 million giving activities.

Our business allows consumers, who may feel disconnected from the problems of the developing world, to become involved in social problems while still purchasing for themselves. For example, shoe brands like TOMS promise to donate one pair of shoes for every pair purchased. Soapbox gives soap to a needy child with every purchase. Watch company WeWood plants a tree every time you buy a watch. They have helped socially-conscious consumers purchase products and feel good about providing help to others.

For a year and half, kids sent hurtful messages like “You are ugly.” or “Why are you still alive?” to Rebecca Sedwick. In 2013, Rebecca, then 12, couldn’t stand it anymore. She took her own life near her home in Florida. Soon afterward, Trisha Prabhu read about the story. “I was surprised and heart-broken,” said Trisha, now 15, who is from Naperville, Illinois, “I know that I had to do something to stop this from ever happening again.”

Trisha did some research. Studies show that one fourth to half of all teens in the US have been cyberbullied (网络欺凌). Experts say that if you are ever bullied online, you should tell a trusted adult. Tell the cyberbully to stop, and prevent him or her from contacting you again. Print and save messages to share with the police. This is good advice, agrees Trisha. But these methods all take place after the bullying has already happened. Trisha had a different idea. Why not teach cyberbullies to stop before they post these messages?

Trisha’s research won awards, including a prize in the Google Science Fair. Then, Tresah built the ReThink app (应用软件). It is programmed to recognize words or phrases that could be hurtful. When that happens, different warning messages come out. “Don’t say things that you may regret later!” says one message. Others ask, “Are you sure you want to say this?” and “Are these words really yours?”

Now Trisha is working on a version(版本) of ReThink for computers. “I am a big dreamer,” she says. “I want to stop cyberbullying before the hurt is done.”

1.What do we know about Rebecca Sedwick?

A. She was one of Trisha's best friends.

B. She sent hurtful messages to others.

C. She ended her life at the age of 12.

D. She went to Florida to study further.

2.What is Trisha’s suggestion for stopping cyberbullying?

A. Stop talking with the cyberbully.

B. Stop the messages before they are sent.

C. Turn to your parents or close friends

D. Show the messages to the police at once.

3.What is the third paragraph mainly about?

A. People's attitudes to the ReThink app.

B. Trisha's research on cyberbullying.

C. How the ReThink app works.

D. The Google Science Fair.

4.Which of the following can best describe Trisha?

A. Honest and careful. B. Helpful and clever.

C. Proud and impolite. D. Strange and impatient.

I ran into a local store today to pick up a few things. With an important meeting to attend, I was in a hurry , so I didn’t take a cart (手推车) on my way inside. As I walked between the shelves in the store, I passed by a young couple and their baby. I continued going through the store, picked up a few items I needed and ended up standing behind this couple in the checkout line.

While waiting, I noticed that the young father was holding his money tightly and nervously. The young mother was carrying a baby in her arms and asked the cashier (收银员) for a job application.

When the total was rung up, they had to pick items out of their cart because they didn’t have enough money. But all their items were basic necessities(必需品) that they needed most. It just broke my heart to watch the couple try to think about what they could do without. However, they were able to whittle down their items and paid the bill with the money that they had.

After they left, I quietly asked the cashier to add those items to mine. The cashier rang everything up, and then got me a shopping cart. We put in their items and I hurried over to their car. “This is for you,” I told them.

The young father just looked at me with such appreciation and thanked me. I will never forget the expression in his eyes. As I was getting into my car, they drove over. The young mother said, “Miss, thank you so much.”

Tears welled up in my eyes---as they are again now, while I write this. “You are so welcome. Pay it forward some day,” I replied.

1.The underlined phrase “whittle down” in Paragraph 3 probably means “__________”.

A. add to B. break down

C. pay for D. cut down

2.The author felt __________ to watch the couple taking some items out.

A. angry B. sad

C. excited D. interested

3.It can be inferred from the passage that _________.

A. the young mother didn’t have a job then

B. the young father felt so sorry to accept help

C. the cashier treated the young couple impolitely

D. the young couple bought something unnecessary

A. what a great plan she made

B. to take a cart while shopping

C. to help those who are in need

D. how to pick out basic necessities
