The 2009 outbreak of HINI is a new kind of influenza virus, commonly referred to as “swine flu”. It is thought to be a break of four known kinds of influenza. A virus subtype H1N1: one endedmic(流行病) in humans, one endemic in birds, and two endemic in pigs (swine). The source of the outbreak in humans is still unknown, but cases were first discovered in the U.S. and soon after in Mexico.
According to the U.S. Centers for Disease Control and Prevention(CDC)，it is not yet clear how serious this new virus actually is compared with other influenza viruses, although on May 26 they stated that new cases in the U.S. have probably reached the hightest point, and most cases have so far been mild relative to “seasonal flus”. But because this is a new virus, most people will not have immunity(免疫性) to it, and illness may eventually become more severe and widspread. The H1N1 flu mainly spreads in the same way that regular “seasonal influenza” spreads through the air from coughs and sneezes or touching those infected. It cannot be transmitted from eating cooked pork or by being in close contact with pigs.
As yet there is no vaccine(疫苗) available to prevent infection although companies are in the planning stages for having one available later this year. But there is concern that the virus could vary again over the coming months, leading to a new and potentially more dangerous flu outbreak later in the year, and a vaccine that will be less effective in preventing its spread.
As of May 27, the virus had spread to more than 50 countries; however, over 80% of reported deaths have taken place in Mexico. According to the CDC, the fact that the flu’s infection activity is now monitored more closely may help explain why more flu cases than normal are being recorded in Mexico, the United States and other countries.
1.The 2009 outbreak of H1N1 is thought to ________.
A.be concerned with four endmics
B.have come from the virus from pigs
C.occur because of unknown virus in Mexico
D.be caused because of people without immunity
2.According to the U.S. Centers for Disease Control and Prevention, ______.
| A.most people won’t be infected with the flu B.the H1N1 will not be too mild to cause many deaths in the world C.the present situation allows of no optimist D.H1N1 can be transmitted by touching pigs |
3.To make people worried more is that ________.
| A.no effective vaccine can prevent the virus from spreading B.the virus will mutate in the following months C.a seasonal influenza will break out D.the newly-developed vaccine will lose effectiveness |
4.From the passage we can learn that ________.
A.every country is watching closely the spreading of the H1N1
B.more than one-fourth of the deaths from the H1N1 are in Mexico
C.only the United States and Mexico recorded the cased of influenza
D.effective medicine has been produced to cure the H1N1

The year 2018 will mark the 100th anniversary of the deadliest influenza outbreak in history. It is estimated that the influenza pandemic(瘟疫) of 1918 killed more than 50 million people around the world. Other estimates go much higher. Because of a lack of medical record—keeping, we may never know the exact number.
The influenza was a fast killer. Some victims died within hours of their first symptoms. Others died after a few days. “their lungs filled with liquid and they choked to death. ”The 1918 flu pandemic was also different from other outbreaks. It struck many young, healthy people. Viruses usually affect sick or old people.
Although modem medicine effectively controls many diseases, influenza remains difficult to protect against, The World Health Organization estimates that every year influenza kills 250, 000 to 500, 000 people around the world. Each year, medical scientists develop flu vaccines(疫苗) which offer immunity(免疫)from some influenza viruses. But they can only guess which form of the virus will spread.
Health officials remain concerned about another flu pandemic. New forms of the flu virus appear regularly. One example was the “swine flu”or H1N1outbreak in 2009. Anthony Fauci, Director of the National Institute of Infectious diseases in the United States says that virus caused a true pandemic.
To stop the next pandemic, scientists are now researching how to create a universal influenza vaccine. In October 2017, Vanderbilt University Medical Center in the U. S. announced the Universal Influenza Vaccine Initiative. The university said researchers are leading an international effort to develop a universal influenza vaccine that will protect everyone against all forms of the flu anywhere in the world. The university added that researchers will begin tests in early 2018, the Human Vaccines Project, a public—private partnership, is funding the project. However, until a universal influenza vaccine is available, today’s seasonal flu vaccine remains important.

How is this virus transmitted?
This is an outbreak of disease that started in Wuhan, one of the central Chinese cities. It’s caused by a novel coronavirus that means it’s brand-new. 1.
What are the symptoms?
The virus is from a family called the coronaviruses. The symptoms of this illness are pretty mundane (平 凡的) on the face of it: it’s a dry cough fever and then breathing problems. 2. However, as for the more severe cases, people have gone on to develop viral pneumonia, and all the deaths have been among those people.
3.
This brand-new coronavirus came from animals, and it’s believed that the source was actually a seafood market in Wuhan, which also sells wild animals. So far all the cases have come out of Wuhan. But some people haven’t picked it up there.
Should I be panicking about this outbreak?
As we can see, older people are ending up in hospital with the virus. They’re usually over 40, and the very youngest person diagnosed is about 13 or 14 years old. So it doesn’t appear to be affecting small children.
4.. Basically, their immune systems are not very strong, and they’re going to find it very hard to fight off a virus.
It’s necessary for ordinary people to wear masks and doctors should wear protective clothing.
How is this virus transmitted?
We’ve only just discovered that the new coronavirus is actually transmitted from one person to another. It was hoped at first actually that it just came from animals as all coronaviruses do. 5. .So we’ve got people to people transmission, because the market has been closed for sometime, and there are cases in people who’ve never been near it.
A.It seems quite mild in lots of people.
B.Where have cases been confirmed so far?
C.It is so new that actually it doesn’t have a name yet.
D.People diagnosed with viral pneumonia will die.
E.It is a brand-new virus so we don’t know how it’s going to behave.
F.Those confirmed cases who have died tend to have heart disease or cancer already.
G.Now it looks as though it is actually passed from one human being to another, however.

Controlling the Ebola virus outbreak at the source in West Africa is the most effective way to decrease international risk of transmission, according to a research paper.
If the epidemic(时疫) persists and grows, it's likely there will be more cases(病例) of the deadly virus exported to other countries, including Canada, via air travel, said Dr. Kamran Khan, a physician and researcher at St. Michael's Hospital.
Dr. Khan, who examines global airline travel patterns to predict the spread of diseases, said that every month, three Ebola-infected travellers are likely to leave West Africa, which is experiencing a widespread outbreak of the virus -- and this number would only increase as the epidemic grows.
Dr. Khan and his co-authors said it is essential that other countries, their public health agencies and hospitals should be prepared. The risk of international spread would be further _____ if this epidemic were to take hold in other countries, especially those with weak public health systems.
"The international community must be mindful and be ready to support the early detection and control of cases." Dr. Khan said.
Dr. Khan noted that of the almost 500,000 travellers who flew on commercial flights out of Guinea, Liberia or Sierra Leone in 2013, more than half were headed to destinations in five countries: Ghana (17.5 per cent, Senegal (14.4 per cent), the United Kingdom (8.7 per cent, France (7.1 per cent) and Gambia (6.8 per cent). More than 60 per cent of travellers from those countries in 2014 are expected to have final destinations in low- or lower-middle income countries.
"Given that these countries have limited medical and public health resources, they may have difficulty quickly identifying and effectively responding to imported Ebola cases”, said Dr Khan.
1.How does Dr. Khan predict the spread of diseases?
A.By doing experiments
B.By examining global airline travel patterns
C. By setting up a model
D. By collecting the data of the cases
2.We can fill in the blank in Paragraph 4 with _____.
A. decreased B. increased
C. avoided D. predicted
3.In low income countries, ______.
A. it is easy to identify imported Ebola cases
B. people have rich medical resources
C. imported Ebola cases may not be effectively responded to
D. travelers are not allowed to go to some places

NEW YORK, May 19—A new, more destructive version of the “Love Bug ” virus is slowly spreading across the world, but so far the damage is small compared with its former version.
The new Love Bug virus creates disorder.
Richard Saunders of anti-viral firm Symantec said the virus only affected a dozen companies around the world.
“While it is a nasty virus, it’s not spreading anywhere near the rate Love But or (last year’s ) Melissa was spreading,” Saunders said.
“New Love” is similar in form to the Love Bug, which swept the world two weeks ago and caused more than $ 10 million in damages. But it’s much more destructive. The virus appears as an attachment to an e-mail whose subject begins with “FW”
If a user clicks on the attachment’s scroll-like icon（卷轴样的图标）, every file on his hard drive is destroyed.
“Basically, it’s going to destroy your machine, ” said Eric Chine, chief researcher at Symantec’s anti-virus lad in the Netherlands.
The Love Bug only killed a small set of files, including graphic files. This virus even wipes out the Windows operating system.
Attorney General Janet Reno warned the public at a news conference today to be careful of any suspicious e-mail with attachments. “Do not open it, even it comes from a trusted source.” she said.
Don’t Open That Attachments.
Like the Love Bug, after the e-mail attachment is opened and the virus is carried out, New Love sends itself to everyone in a victim’s Microsoft Outlook address book. Fortunately for users, the lesson is the same as from the Love Bug: If you see a message with an attachment whose name ends in vbs, with a scroll-like icon, don’t click on the attachment. Also like the Love Bug, this virus only affects computers running Windows 98, NT 4.0 Windows 95 with Internet Explorer 5.0 and can only spread if users rely on a Microsoft Outlook address book for e-mail. Microsoft will soon give a fix for Outlook that warns people or suspicious attachments, the company said.
68. According to the passage, so far the new Love Bug virus _________.
A. has made the whole world disordered
B. causes more damages than other forms of virus
C. is the newest and spreading the fastest
D. has affected 12 companies around the world
69. Computer users are warned in this article _________.
A. not to suspect e-mails beginning with “FW” subjects
B. not to open attachment of doubtful e-mails
C. to stop using Microsoft Outlook address book
D. to examine the Windows Operating System carefully
70. It can be suggested from the passage that _________.
A. the mail sent by a friend is surely free of the virus
B. the Microsoft Company will take action against the virus
C. all computers running Windows 98 will be affected
D. the users can not find the way to deal with the Love Bug.
71. The author writes this passage in order to _________.
A. compare some types of virus
B. explain how the Love Bug is formed
C. tell the readers something about a new virus
D. remind computer companies to kill the virus
