Michael, a typical American, stays home on workday. He plugs into his personal computer terminal in order to connect with the office. After work he puts on his headphones, watches a movie on his home video recorder or plays baseball on the computer. On many days, Michael does not talk to any other human beings, and he does not see any people except the ones on television. Michael is imaginary, but his life style is very possible. The inventions of modern technology seem to be cutting us off from contact with our fellow human beings.
The world of business is one area which technology is isolating us. Experts say, for example, that many people will soon be able to work at home. With access to a large central computer, employees such as office clerks, insurance agents and accountants could do their jobs at display terminals in their own homes. They would never have to actually see the people they’re dealing with. In addition, the way employees are paid will change. Workers’ salaries will be automatically paid into their band accounts, making paper checks unnecessary. No workers will stand in line to receive their pay or cash their checks. Personal banking will change, too. Customers will deal with machines to put in or take out money from their accounts.
Another area that technology is changing is entertainment. Music, for instance, was once a group experience. People listened to music at concert halls or in small social gatherings. For many people now, however, music is an individual experience. Walking along the street or sitting in their living rooms, they wear headphones to build a wall of music around them. Movie entertainment is changing, too. Movies used to be social events. Now, fewer people are going out to see a movie. Many more are choosing to wait for a film to appear on television or are borrowing videotapes to watch at home. Instead of laughing with others, viewers watch movies in their own living rooms.

The Vienna-based researchers showed that dogs will stop doing a simple task when not rewarded if another dog, which continues to be rewarded, is present．
The experiment consisted of taking pairs of dogs and getting them to present a paw for a reward．On giving this “handshake” the dogs received a piece of food．One of the dogs was then asked to shake hands, but received no food．The other dog continued to get the food when it was asked to perform the task．
The dog without the reward quickly stopped doing the task, and showed signs of anger or stress when its partner was rewarded．
To make sure that the experiment was really showing the interaction between the dogs rather than just the frustration of not being rewarded, a similar experiment was conducted where the dogs performed the task without the partner．Here they continued to present the paw for much longer．
Dr Frederike Range from the University of Vienna says this shows that it was the presence of the rewarded partner that was the greater influence on their behaviour．
“The only difference is one gets food and the other doesn’t, they are responding to being unequally rewarded．” she said．
The researchers say this kind of behaviour, where one animal gets frustrated with what is happening with another, has only been observed in primates(灵长类) before．
Studies with various types of monkeys and chimpanzees show they react not only to seeing their partners receiving rewards when they are not, but also to the type of reward．
The dog study also looked at whether the type of reward made a difference．Dogs were given either bread or sausage, but seemed to react equally to either．Dr Range says this may be because they have been trained．

A．found another dog was given nothing

Since weeks ago, China has been involved in a worldwide A/H1N1 flu that has already killed more than 80 people in the middle of May, 2009, in Mexico and has turned into a global pandemic．
The central government has asked people entering China from the virus-hit countries to report flu-like symptoms(症状)to the authorities．In an emergency notice issued on Saturday night, the country’s top quality watchdog ordered the Customs to check passengers’ temperature, too．
A Beijing airport official Li said Customs officers are on a high alert(警戒)level．
“Three temperature detectors are now in operation．We’re ready with protection garments and equipment, too．Passengers flying in from Mexico and other A/H1N1 flu-hit countries are being monitored closely,” he said．
The Ministry of Health, however, said yesterday there was no evidence to suggest that a person would contract the disease by eating pork．
Hong Kong, too, has raised its alert level against the flu to “serious”．Secretary for Food＆Health, Mr．York Chow urged people to avoid visiting places from where A/H1N1 flu cases have been reported, and said the virus would be added to Hong Kong’s list of the diseases which have been noticed．
The terrible A/ H1N1 flu has been contracted by about 4000 people in Mexico, and most of the killed were aged between 25 and 45．
The virus has also infected about 5,000 people in the US．The US Center for Disease Control said this kind of virus is spreading from human to human, raising fears of a global pandemic．
53．What is the passage mainly about?
A．A/H1N1 flu killed more than 80 people．
B．A/H1N1 flu is spreading from human to human．
C．China has begun to take steps to prevent A/H1N1 flu．
D．All the people are strongly affected by A/H1 N1 flu．
54．The underlined word “pandemic” in the first paragraph probably means ..
A．death B．panic C．enemy D．disease
55．Why does the flu cause global fears?
A．Because most people in the world eat pork．
B．Because it’s spreading from human to human．
C．Because we still don’t know the cause of it．
D．Because it has infected about 5, 000 people．
56．We can infer from the passage that．
A．passengers from the United States are being monitored closely

C．students in the middle school are most likely infected by A/H1N1 flu
D．Mr．York Chow said that the virus had been added to Hong Kong’s list of the diseases

Most of us think that when we step under a shower we’re getting clean．We are, but we’re also giving a home to lots of tiny little creatures we didn’t even know about．
A showerhead carries thousands of bacteria (细菌) called Mycobacterium．These can cause problems like coughs and tiredness, and a general feeling of poorliness (身体不舒服)．When you turn on the water, the bacteria go from the showerhead onto and into your body．
This is a finding of Norman R．Pace and his team at the University of Colorado, in the US．The scientists investigated bacteria in all kinds of human environment, including showers．
Pace's team looked at 45 showerheads in nine American cities．They discovered that 30 percent of them had large amounts of flying Mycobacterium．
But Pace said that they pose few threats to the health．Only those with a frail (脆弱的) immune (免疫的) system might need to worry．
He told the New York Times that the bactertia are not as unpleasant as might be thought．He said that having a shower is no more dangerous than anything else we do in the morning．
But for those who feel sick about the idea of all those microorganisms (微生物), he had some advice．
Let the water run for 30 seconds before getting into the shower．Why? The number of bacteria is smaller than when the water is just turned on．If that seems like a waste of water, he added that you could also change your showerhead every few months．
But Pace had good news too．He has also been testing the air in US subways．Apart from iron particles (粒子), which are ground off the track by the wheels of trains, subway air is fresh．The reason is that a train’s movement pumps fresh outdoor air into the tunnels(隧道)．
Pace explained that he wanted to understand the natural microbial(微生物的) environments of public places．This kind of knowledge might help detect the microbes to be used in a bioterrorist (生物恐怖分子) attack．
49．According to the finding of Norman R．Pace, after taking a shower, we might ______．
A．get much dirtier B．be covered by bacteria
C．get a frail immune system D．catch a cough or feel tired
50．Pace’s research into showers shows that ______．
A．there is no reason to fear microorganism
B．shower water contains much less bacteria after being left to run for 30 second
C．having a shower in the morning is more dangerous than at other time
D．of 45 showerheads surveyed in nine cities, 30 carried large amounts of Mycobacterium
51．According to the research of Pace’s team, which of the following contributes to fresh air in US subways?
A．Train wheels． B．Iron particles．
C．The movement of the trains． D．Air conditioners on the trains．
52．The word “detect” in the last paragraph probably means “______”．
A．to discover B．to protect C．to make D．to prevent

At the end of my senior year of high school, I got a job working at a local coffee shop．I thought the job would be easy and stress-free．I pictured myself pouring the best coffees, making delicious doughnuts (炸面包圈), and becoming friends with regular customers．
I wasn’t expecting the people with enormous orders, the women who complained that the coffee was much too creamy (含乳脂的), or the men who wanted their iced coffees remade again and again until they reached perfection．I couldn’t seem to please anyone．
One rainy day, one of my regular customers came in looking upset．He said he felt like getting in bed, pulling the sheets up over his head, and staying there for a few years．I knew exactly how he felt．
Before he left, I handed him a bag along with his iced coffee．He was surprised, since he hadn’t ordered anything but coffee．I had given him his favorite type of droughnut．
“It’s on me,” I told him．“Have a nice day．”
He smiled and thanked me before heading back out into the rain．
The next day, it was still raining．I spent my afternoon hanging out the window handing people their orders．I was completely wet and freezing cold．Worse, no one was tipping that day．Every time I looked into our empty tip jar, I grew more depressed．
In the evening, the customer from the day before drove up to the window．He handed me a pink rose and a note．He said that not many people took time to care about others and he was glad there were still people like me in the world．With a friendly wave, he drove away．
I ran to the back of the shop and read the note．It read:
Christine,
Thanks for being so sweet, kind and thoughtful yesterday．It is so nice to meet someone who’s indeed nice．Please don’t change your ways! Have a great day! –Hank
After that, whenever I felt depressed or sick of coffee, I thought of Hank and his kindness．Then I would smile, hold my head up high, clear my throat and ask politely, “How can I help you?”
