At one time, computers were expected largely to remove the need for paper copies of documents(文件) because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.

    It is difficult to measure the quantity of paper used as a result of use of Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. “I feel in my bones this revolution is causing more trees to be cut down,” says Ted Smith of the Earth Village Organization.

    Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a on-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers.

    Does all this mean environmental concerns (环境问题) have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away.

    “I guess people believe that the problem is taken care of, because of recycling（回收利用）,” said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity.

    The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.

    A person's chances of falling ill from a new strain (菌株) of flu are at least partly determined by the first strain they ever met with, a study suggests.

    Research in Science Journal looked at the 18 strains of influenza A ( 甲型流感) and the hemagglutinin protein (红血球凝集素蛋白) on its surface. They say there are only two types of this protein and people are protected from the one their body meets first, but at risk from the other one. A UK expert said that could explain different patterns in flu pandemics (流行病).The researchers, from University of Arizona in Tucson and the University of California, Los Angeles, suggest their findings could explain why some flu outbreaks cause more deaths and serious illnesses in younger people. The first time a person's immune system meets a flu virus, it makes antibodies targeting hemagglutinin protein that sticks out of the surface of the virus — like a lollipop (棒棒糖).

    Even though there are 18 types of influenza A, there are only two versions of hemagglutinin. The researchers, led by Dr Michael Worobey, classed them as "blue" and "orange" lollipops. They said people born before the late 1960s were exposed to "blue lollipop" flu viruses — H1 or H2 — as children. In later life they rarely fell ill from another "blue lollipop" flu — H5N1 bird flu, but they died from "orange" H7N9. Those born in the late 1960s and exposed to "orange lollipop" flu — H3 — have the opposite pattern.

    His team looked at cases of H5N1 and H7N9 — two kinds of bird flu which have affected hundreds of people, but have not developed into pandemics. The researchers found a 75% protection rate against severe disease and 80% protection rate against death if patients had been exposed to a virus with the same protein version when they were children.

    Dr Worobey said the finding could explain the unusual effect of the 1918 "Spanish flu" pandemic, which was more deadly among young adults. "Those young adults were killed by an H1 virus and from blood analysed many decades later there is a pretty strong indication that those individuals had been exposed to a mismatched H3 as children and were therefore not protected against H1. The fact that we are seeing exactly the  same pattern with current H5N1 and H7N9 cases suggests that the same fundamental processes may govern both the historic 1918 pandemic and today's contenders (斗争者) for the next big flu pandemic."

    Jonathan Ball, professor of University of Nottingham, said, "This is a really neat piece of work and provides a reason why human populations have been sensitive to different strains of bird influenza over the past 100 years or so. The findings are based on analysis of patient records and they certainly need further proof in the laboratory, but nonetheless the results are pretty amazing and inspiring."

    In an attempt to make the group texting experience more bearable, we've put together a list of strategies and things to consider when messaging multiple people at the same time.

    Think about who you're texting

    Whether you're in a group text with your parents, schoolmates, or work friends, consider what you're sharing - and who you're sharing it with. Parents may not be interested in the latest memes and explaining their slight differences can be a pain.

    Be mindful of people's schedules

    While not everyone's schedules are the same, most people are busy during typical work week hours, so sending a million mid-day texts isn't always ideal. Some people rise early or get to bed early. Avoid including them on a text that you know will ask for a bunch of responses super late at night or early in the morning.

    Name the group

    If you have the ability to name the texting or messaging group you're on - this is possible on an iPhone or when using Facebook Messenger - I strongly recommend you do so. Though not everyone will love the name you choose, naming your group will help you keep track of all your ongoing conversations.

    Don't write lots of one-word texts

    Please, if you must text in the group thread, don't deliver multiple short answers in a row. Everyone will despise you. If you have something pressing to share or say, try to sum it up in one brief text. If you have a lot to say, maybe try writing an email.

    Damn I seriously don't have time to be on my phone when I'm at work, and my friends keep texting on the group chat and I'm at a loss.

    If feels like every time my mother and I start to have a conversation, it turns into an argument. We talk about something as simple as dinner plans and suddenly, my mother will push the conversation into World War？She'll talk about my lack of a bright future because I don't plan to be a doctor. And much to her disappointment, I don't want to do any job related to science, either. In fact, when I was pushed to say that I planned to major （主修） in English and communications, she nearly had a heart attack.

    "Why can't you be like my coworker's son？"she bemoans all the time. Her coworker's son received a four year scholarship and is now earning 70, 000 dollars a year as an engineer. I don't know what to answer except that I simply can't be like Mr Perfect as I've called the unnamed coworker's son. I can't be like him. I'm the type of person who loves to help out in the community, write until the sun goes down, and most of all, wants to achieve a career because I love it, not because of fame （名声） or salary.

    I understand why my mother is worried about my future major. I've seen my mother struggle to raise me on her small salary and work long hours. She leaves the house around 6：30 am and usually comes home around 5 pm or even 6 pm. However, I want her to know that by becoming a doctor, it doesn't mean I'll be successful. I'd rather follow my dreams and create my own future.
