In today"s world, we rely on computers as never before. They are used for everything from ordering a pizza to running hospitals and military defense systems. Banking and credit card information is stored and accessed by computers. So what happens when a computer gets infected with a virus? One effect is that people"s access to their e-mail accounts is cut off. A more serious possible consequence is that billions of dollars could be lost.
A virus is a computer program that copies itself onto other programs and infects them. Similar to an easily spread disease, a computer virus goes from computer to computer, either adding to or changing the tasks a program is designed to do.
The first computer viruses were created in the mid "80s and had varying effects. Some caused files to be deleted, or made the letters on the screen appear to fall off. Others displayed a specific message once the computer was turned on.
Viruses today are much more widespread and dangerous than ever before. Perhaps the most damaging to date has been the "I Love You" virus. "I Love You" appeared in May 2000 and has possibly been the most destructive virus in terms of monetary loss.
The virus is released when an attachment to a fake e-mail message is opened. By changing the names of files on computers, "I Love You" makes them difficult to access. It also searches for important personal information, including passwords, which it sends to a web site for others to see.
It is estimated that more than 45 million people in 20 countries have had their computers infected by the "I Love You" virus. Some say the cost of repair and lost business has been more than US$10 billion.
If you own a computer, it is important to keep it in good health by installing an anti-virus program. If updated frequently, it will protect your e-mail access--not to mention your wallet.
68. What does "virus" mean in the article?
A. An easily spread disease.
B. A contagious (传染的) computer program.
C. An extremely small organism (生物) which causes disease.
D. A parasite (寄生虫) in computer.
69. How does "I Love You" virus spread?
A. It is spread when an e-mail account is opened. B. It is spread through on-line chatting.
C. It is spread through e-mail.                 D. It spreads from web site to web site.
70. Which of the following is the best way to guard against virus?
A. To load an up-to-date anti-virus program into our computer
B. Not to use an e-mail account.
C. To upgrade our computer.
D. Not to use the Internet.
71. What is the purpose of the article?
A. To warn us against virus.            B. To remind us the importance of being healthy.

When important events are happening around the world, most people turn to traditional media sources, such as CNN and BBC for the news．However, during the war in Iraq in 2003, many people followed the war from the point of view of an unknown Iraqi citizen who called himself “Salam Pax ” ．(Salam Pax means peace)
Salam Pax wrote a diary about everyday life in Baghdad during the war, and posted it on his website．Pax’s online diary was a kind of website known as a “blog”．Blogs are online diaries, usually kept by individuals, but sometimes by companies and other groups of people．They are the fastest growing types of website on the Internet．
A blog differs from a traditional website in several ways．Most importantly, it is updated much more regularly．Many blogs are updated every day, and some are updated several times a day．Also, most blogs use special software or websites, which can help ordinary people easily set up and start writing their own blogs．
There are many different kinds of blogs．The most popular type is an online diary of links where the blog writer surfs the Internet and then posts links to sites or news articles that they find interesting , with a few comments about each one ．Other types are personal diaries, where the writer talks about their life and feelings．Sometimes these blogs can be very personal．
There is another kind of blogging, called “moblogging ”, short for “ mobile blogging ”．
Mobloggers use mobile phones with cameras to take photos, which are posted instantly to the Internet．The use of mobile phones in this way made the headlines in Singapore when a high school student posted a movie he had taken of a teacher shouting at another student on the Internet．Many people were shocked by what the student did, and wanted phones with cameras to be banned from schools．
Many people think that as blogs become common, news reporting will rely less on big media companies, and more on ordinary people posting news to the Internet．They think that then the news will be less like a lecture, and more like a conversation, where any one can join in．

Every year there are hundreds of earthquakes in different parts of the world. In September, 1923, Tokyo and Yokohama were

both destroyed by an earthquake and the fires that followed it. They had to be completely rebuilt. One of the most serious earthquakes was in

China’s Shanxi province in 1556. It killed almost one million people.
We measure an earthquake’s strength on the Richter Scale. The Richter Scale was introduced in 1935 in Southern California in the USA. It measures earthquakes on a scale of one to ten. Any earthquake measuring five or more is usually serious.
The Earth’s crust(地壳) is made up of rock called plates. As these plates move, they sometimes crash against each other, causing the crust to quake. In cities such as Tokyo, where small quakes happen quite often, many modern buildings are designed to be flexible so when the Earth moves, they move with it.
Earthquakes can also break up gas and oil pipes. This can cause fires to break out, which can do as much damage as the earthquake itself.
Another effect of earthquakes is tsunamis. These are huge waves created by earthquakes beneath the sea. They can be many meters high and cause great damage to coastal towns and cities, China, Japan, Russia and the USA have the highest occurrence(发生) of earthquakes in the world.

Is there a nationwide shortage of nurses? It’s hard to say．However, some characteristic symptoms often indicate that there is indeed a shortage．
One symptom is the vacancy rate, or the percentage of budgeted positions that are unfilled．New England’s hospitals currently report that an average of 7 to 12 percent of their registered nurse positions are vacant, the highest level since the last shortage in the late 1980s．Vermont has a relatively low vacancy rate, at 7．8 percent．But its vacancies were at 1．2 percent just five years ago．
Another symptom is the increased use of stopgap measures to fill empty positions．For instance, many nurses report an upswing in how frequently they are asked to stay past their shifts．According to Murphy, working in the St．Elizabeth’s Hospital, “The shortage has definitely created a lot of opportunities of overtime for our nurses, whether they want them or not．” Similarly, a national survey of registered nurses shows that in an average week, nurses in the U．S．work 2．4 more hours than they are scheduled to．Much of this extra time is voluntary, as nurses earn overtime pay when they stay to fill in blanks in the schedule．
When they can’t fill open positions by more traditional means, health care providers hire temporary staff to tide them over．Travelling workers are the largest part of the temporary health care workforce, hired for thirteen-week reduction at health care facilities facing short-term lack of workers．Temporary workers, mainly nurses, cost hospitals $ 7．2 billion in 2000．
“Any successful solution to the shortage depends on convincing more people to become nurses, and that is not an easy goal to reach．To achieve it,” says Buerhaus, “society needs to place more value on nursing．Legislation （法规） can’t do that – it should come from people．” And if this continues, we might have to learn to care for ourse

lves in the hospital．
小题1:The temporary staff hired by a hospital _______．

A．cost a large part of the hospital’s budget

B．meet the need for nurses in the hospital for a short time

C．should work on a weekly basis and on a scheduled timetable

小题2:According to Buerhaus, what is a successful solution to the nurse shortage?

A．To convince people of the benefits of being a nurse．

B．To ask the government for help to work out specific legislation．

C．To publicize the past achievements of nurses．

D．To make people aware of the importance of being a nurse．

小题3:What’s the probable meaning of the underlined word “upswing” in Paragraph 3?

A．Symptom

B．Decrease

C．Increase

D．Figure

小题4:What’s the author’s attitude towards nurse shortage?

Researchers have just offered evidence in a study that says obesity appears to spread through social ties, much like a virus. When one person gains weight, their close friends often follow, but the finding might also offer hope.
If friends help make obesity acceptable, then might also be influential in losing the fat. The researchers note that support groups are already an effective tool in dealing with other socially influenced problems, like alcoholism.
The findings appeared in the New England Journal of Medicine, The researchers used information collected from 12,000 people. It was collected between 1971 and 2003 as part of the Framingham Heart Study.
The information was highly detailed. There was even contact information for close friends of the people in the study.
The researchers examined more than 40,000 social ties. They found that a person’s chances of becoming severely overweight increased by 57% if a friend had become obese.
Nicholas Christakis of Harvard Medical School was a lead investigator in the study. He says there is a direct causal relationship between a person getting fat and being followed in weight gain by a friend.
The study found that the sex of the friends was also an influence. In same-sex friendships, a person had a 70% increased risk of becoming obese. Men had a 44% increased risk of becoming obese after weight gain in brothers. In sisters, it was 67%. Between husbands and wives, it was a little less than 40%.
The researchers also considered the effect of where people lived in relation to each other. James Fowler of the University of California, San Diego, was the other lead investigator. He says a friend who lives a few hundred kilometers away has as much influence as one in the same neighborhood. He says the study demonstrates the need to consider that a major part of people’s health is tied to their social connections.
Both investigators say their research shows that obesity is not just a private medical issue, but a public health problem.
67. What does the underlined sentence in Para2.mean?
A. Obesity has a negative influence on a close friend.
B. Friends might also play a part in losing weight.
C. One might have a positive influence on one’s friend.
D. Friends usually don’t follow each other to lose weight.
68. Who is mostly likely to gain weight?
A. A man who has a fat brother.
B. A husband who has a fat wife.
C. A wife who has a fat husband.
D. A woman who a fat female friend.
69. Which of the following statements doesn’t the passage agree with?
A. You are sure to lose weight if you have a skinny friend.
B. If one gains weight, one’s friends are likely to get fat.
C. A person’s health is closely linked with his /her social relationship.
D. Even if the friend lives far away, the influence still remains.
70. The reason why the study involves both family members and friends is that _____.
A. researchers fail to find a more different sample
B. researchers have different ideas for family members and friends
C. researchers can meet these people regularly
D. researchers can compare the results
