Along with global warming and the Ebola virus...

Along with global warming and the Ebola virus，this year, something far less life-and society-threatening also spiraled out of control：email．

It was long ago invented as something to make us more productive．But what productivity expert would ever say that it's a good thing that instead of working，we now“answer email? Or that on some days，I am unwilling to leave my desk to head into a meeting because it means taking my finger off the keyboard and knowing 1 will return to a flood of new messages waiting patiently for my total attention?

Some people struggle for“inbox zero”．But like many people，I now get so much junk mail that if I were to adopt such a goal，I would spend every workday doing nothing but deleting emails．To make sure nothing important gets buried，I have developed an embarrassinglv old system of keeping a pen-and-paper list of emails that need responses on a series of Post-It notes．As far back as 2007，Fred Wilson famously declared “email bankruptcy”．I'm close to doing the Same．

But I may not need to．I predict that 2015 will mark the beginning of the end of emails．Already, some tools have emerged(出现)over the years，like software Freedom which disables access to the Internet for chosen periods of time．Corporations have gradually been adopting stricter email policies：A few years ago，Volkswagen said it would stop sending emails from its servers to company-owned BlackBerrys after the end of its workday．

But this great hope is largely the optimist in me speaking，and I give this prediction small chances compared to some of our others．As Tony Hsieh once told me，the problem with email is that it is a“good—enough”solution．Some technologies stay around just because there isn’t anything better．It’s probably right．But my wish is that 2015 is the year when truly effective email management solutions go from good to great-and that email volume goes from crazy to reasonable．We’ll a11 be better for it．

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?

A. There are no effective drugs to treat Ebola by far.

B. Ebola is now very common in Guinea.

C. Those with a fever must be infected by Ebola.

D. Females are easier to be infected by Ebola.

What do you get when you mix six little pigs, four monkeys and the deadly Ebola virus? Bad news, according to a recent experiment by Canadian researchers.

The experiment is the first to suggest that the Ebola virus can spread through the air. The study, published in November, detailed how the virus apparently moved from pigs to monkeys without their coming into physical contact. Previously, researchers thought animals had to touch to pass along the virus, which has been blamed for the deaths of more than 1,500 people.

In the experiment, researchers infected six piglets with Ebola. The team then placed the infected piglets in a room with several monkeys. A barrier separated the monkeys from the pigs, so the two species could not touch. And yet, after about a week, two monkeys became sick, infected with the virus. A few days later, the other two monkeys also fell sick with Ebola.

The Ebola virus is named for a river in the Democratic Republic of the Congo in Africa, close to where the germ was discovered. The virus causes high fevers and deadly bleeding disorders in primates, including people and monkeys. It is often deadly. However, scientists previously believed that the virus spread only through direct contact with the blood or other body fluids of an infected person or animal. Other viruses, including the ones that cause chicken pox and the common cold, are known to spread through the air.

Though Ebola too appeared to spread through the air in the laboratory experiment, researchers haven’t documented any cases of airborne infection under normal conditions. Since the discovery of Ebola in 1976, it has infected more than 2,200 people. Of that total, only 13 people fell ill apparently without coming into direct contact with an infected animal or person. If Ebola spreads easily through the air, scientists and doctors would expect to see more such cases.

1.What does the underlined part “Bad news” in Paragraph1 refer to?

A. The animals will only spread the virus to other animals.

B. Canadian researchers have not reached a conclusion.

C. The virus will be spread among people by pigs and monkeys.

D. The pigs and monkeys will get infected with the virus.

2.What have researchers surprisingly found about the Ebola virus recently?

A. The Ebola virus can be deadly to animals in the wild.

B. The Ebola virus can spread without direct physical contact.

C. The Ebola virus can kill humans after they get infected with it.

D. Animals have to touch each other to pass along the Ebola virus.

3.What do we know about the Ebola virus?

a. It was first found in an African country.

b. It spreads totally differently from chicken pox.

c. It cannot spread through other body fluids besides blood.

d. People usually suffer from high fevers after getting infected.

e. It spread only through direct contact with the blood in the past.

A. abe　　 B. ad　　 C. abc　　 D. bcde

4.It is implied about the Ebola virus in the last paragraph that ___.

A. it has killed thirteen people in total through air spreading

B. it cannot cause any human infections under normal conditions

C. spreading through the air is not an efficient route of transmission

D. more than 2,200 people have died because of the infection of the virus

"It's this time of year when the weather starts warming up and frogs start breeding - but they haven't been breeding," says John Wilkinson, research and monitoring officer at the Amphibian and Reptile Conservation Trust (ARC).

Amphibians (两栖动物) are just one of the groups of animals that nature observers fear may have problems reproducing this year, as groundwater levels are even lower now than in the infamously dry summer of 1976, according to the Department for Environment, Food and Rural Affairs (Defra). According to the UK's Centre for Hydrology and Ecology the average rainfall so far this winter has been the lowest since 1972.

"If ponds dry up totally," says Mr. Wilkinson, "you could have lots of dead tadpoles." Drier and windier conditions could also make it more difficult for juvenile amphibians to survive their journeys between wet habitats.

But Peter Brotherton, the biodiversity manager for Natural England, says that "drought is part of nature's cycle", and, at present, a lot of animals, plants and insects are still in hibernation. This means that the population picture is unclear. "However, when we get extreme events, we get animals dying," he says. "And what is worrying is that normally at this time of year we expect soil to be near saturation（湿润）after winter."

Charlie Kitchin, the RSPB's site manager of the Nene Washes in Cambridgeshire, says the 2,000-acre wetland and grassland area is now struggling following two winters with relatively little winter rain and no flooding. One species that could suffer, he says, is the black-tailed godwit（黑尾豫）. "There are only 50 breeding pairs in the country, and we have 40 of them, and everything is bone-dry," Mr Kitchin says.

But one bad nesting season, he says, is "not the end of the world". "One of the features of flood plains is that they're volatile anyway," he adds. "But if they fail to breed another year, the population is likely to dip again."

1.According to the passage animals may have problems reproducing this year mainly due to _____.

2.What really worries Peter Brotherton is that ________.

3.Which of the following is NOT true of Charlie Kitchin’s words?

4.The underlined word volatile in the last paragraph can be replaced by ________.

5.It can be learnt from the text that ______________.
