The deadliest Ebola outbreak in history that has so far killed almost 1000 people in Guinea, Liberia, Sierra Leone and Nigeria in West Africa has caused fear around the world.

The outbreak is unprecedented（空前的）both in infection numbers and in geographic scope. Officials from the World Health Organization (WHO) said earlier this month the outbreak “is moving faster than our efforts to control it”, reported CNN. So far, the battle against the virus doesn’t appear to be slowing down.

The Ebola virus is terrifying no matter where it strikes: It’s a disease with no cure that causes headaches and fever, severe diarrhea(腹泻), vomiting and bleeding and has been known to kill up to 90 percent of its victims.

It is understandable for people to be panicked, but those living outside Africa shouldn’t be particularly concerned about contracting the virus, says a Washington Post article.

This is because transmission of Ebola requires direct contact with an infected person’s blood, vomit or other bodily fluids during the period that he or she is contagious(接触传染的). It is something that is extremely unlikely for anyone but healthcare workers. The virus is not spread by coughing or sneezing.

Media outlets in the US and the UK are using terrifying headlines, wrongly claiming that people infected with the virus have traveled to their countries.

James Ball at The Guardian says the Ebola outbreak in Africa is tragic, but it is important to keep a sense of proportion. Other infectious diseases, including common influenza, are far, far deadlier.

1.What does the author say about the Ebola outbreak in West Africa?

A. It has caused thousands of African deaths.

B. Its spreading speed is beyond people's imagination.

C. It has already traveled to the US and the UK.

D. The fight against it is slowing down.

2.The Ebola virus is terrifying because ________.

A. it cannot be cured at the moment

B. it is easily infected

C. it spreads faster than any other infectious disease

D. it has caused more deaths than other infectious diseases

3.The underlined phrase in the last paragraph means

A. keep a secret                        B. stay calm

C. keep silent                            D. stay away from it

4.What is the author's attitude towards people's panic?

A. Objective.        B. Supportive.        C. Doubtful.        D. Understandable.

2014 saw that the Ebola virus reappeared in Guinea and soon spread into neighbouring Liberia and Sierra Leone, killing over 7,800 people by the new year of 2015. It leads to viral hemorrhagic fever, which is characterized by high fever and internal bleeding etc.

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, Reston, Bundibugyo, and Zaire. The deadliest of the five, Zaire, was responsible for the 2012 out- break, and is believed to be attacking Guinea.

Ebola is naturally found in fruit bats, which pass on the virus to other animals by biting or sucking on their blood. Humans who are suffering from the Ebola infection might have touched the bodily fluids of the infected animals. Once infected, a human becomes a carrier of the deadly virus.

Unfortunately, there are no disease - specific treatments for Ebola. Health - care workers only supply the infected people with physiological saline（生理盐水）to keep them in good condition. Ebola can kill 90% of those infected, especially in underdeveloped societies like those in Africa. 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 infected. The fact that there is no cure for the Ebola virus is what makes the outbreak a challenging one to control.

What’s worse, 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. It is feared that the disease may spread throughout west African countries. For every country, a strong health system can decrease the risk of health attack and lessen the impact of Ebola.

1.What is the function of the first paragraph in the whole passage?

A. To arouse the reader’s concern.

B. To summarize the whole passage.

C. To give a detailed description of Ebola.

D. To introduce the theme of the whole passage.

2.What can we infer about the Ebola virus?

A. It has caused a panic in many countries.

B. It is the most dangerous virus in the world.

C. A strong health system is important to fight against Ebola.

D. Anyone who was infected Ebola will die.

3.Paragraph 3 mainly tells us _________.

A. What the Ebola virus is

B. How the Ebola virus spreads

C. How the Ebola virus is treated

D. How the Ebola virus affects the life

4.Which of the following is true?

New research has shown that loneliness may affect ants to a greater extent than many other living creatures.

It has long been known that loneliness can lead to a shorter life. In humans, it has even been found to be a driver of high blood pressure, sleep disorder, and depression that’s independent of factors like age, race, gender, weight and economic status.

However, loneliness has never been identified as a factor that can cut human lifespan by more than a small part of the average. Ants, on the other hand, appear to be far more sensitive to this stress, with loneliness leading to a surprising 91 percent reduction in lifespan.

That’s at least according to a study that details how “lonely” ants only live up to six days on average. Ants living in a community, on the other hand, were found to live up to about 66 days.

In a series of experiments where ants were picked from their colonies (群体) and separated, they were found to continuously walk without rest,consuming far more energy than they could ever.

The reason for the behavior is that an isolated ant is simple trying to get back to its colony at all costs, and doesn’t know what to do without its nest mates. After all, many entomologists (昆虫学家) would argue that an ant colony is far more a single living entity (实体) than its members.

If you were to take a single part from a clock, it would simply move aimlessly as well, running without a purpose. However, while there is a difference between aimlessness and loneliness, the researchers found that the latter affects lonely ants more directly.

The study indicated that ants can’t even eat alone, as they normally collect some of the food they gather in the field in a specialized organ called a crop.This crop is normally shared with other ants back at a nest,but as for a single ant, it simply just sits there, undigested and useless.

1.How does loneliness influence a person?

A. It can make him very tired of himself.

B. It can leave him in conflict with others.

C. It can lead to him being very independent.

D. It can cause him to suffer from poor health

2.What can be learned from the experiments?

A. Most ants can live about 6 days on average.

B. Lonely ants can become very restless.

C. Human beings are similar to ants in some way.

D. Lonely ants seem to be violent and impatient.

3.Why does an isolated ant walk non-stop?

A. It attempts to return to its colony.

B. It wants to attract other ants to form a colony.

C. It hopes to make signals to its mates.

D. It has to find more food to survive.

4.The author mentioned a clock in the passage_________.

A. to show ants have a biological clock in the head.

B. to prove ants are a well-regulated community.

C. to stress ants are really highly social animals.

D.to compare aimlessness with loneliness.

Everyone wants to have a healthy heart. Still, heart diseases affect more than 1 in 3 adults in the United States. The good news is that some simple, everyday habits can make a big difference in your ability to live a healthy lifestyle. Here are some worst habits for your heart, and how to avoid them.

Watching TV

Sitting for hours on end increases your risk of heart attack and stroke(中风),“some exercise doesn’t make up for the time you sit,”says Harmony R. Reynolds, Why? The lack of movement may affect blood levels of fats and sugars. Dr. Reynolds advises walking around regularly and, if you’re at work, standing up to talk on the phone.

Leaving hostility and depression unchecked

Are you feeling stressed or sad? It can do harm to your heart. While everyone feels this way some of the time, how you handle these emotions can affect your heart health.“Those with stress are in greater danger; research has shown a benefit to laughter and social support,” Dr. Reynolds says. “And it’s helpful to be able to go to someone and talk about your problems.”

Cutting off from the world

It's no secret that on some days, other human beings can seem annoying and too difficult to get along with.

However, it makes sense to strengthen your connections to the ones you actually like. People with stronger connections to family, friends, and society in general tend to live longer, healthier lives.

Everyone needs alone time, but you should still reach out to others and keep in touch whenever you can.

Drinking (too much) alcohol

Sure, studies suggest a small amount of alcohol may be good for your heart. However, too many of us drink over. Too much alcohol is linked to a greater risk of high blood pressure, high levels of blood fats, and heart failure.
