World Book Day falls on April 23 every year．It was set up by the United Nations Educational,Scientific, and Cultural Organization(UNESCO) in 1995 to encourage people, especially teenagers, to discover the pleasure of reading．It is also the day to honor great writers，for example，William Shakespeare，born or dead on that day．

    Many countries celebrate World Book Day．Take UK as an example．On that day，millions of school children can buy books of special price，a much lower price than usual，in any bookstore．It has been done every year since 1998．World Book Day is also celebrated in China. Our Former Premier Wen Jiabao, a bookworm, who does lots of reading every day, has called on people to do more reading. He suggested that young people should spend more time reading．"Books cannot change the world, but people can change the world by changing themselves through reading,” he said．

    Why do people like reading? One big advantage is that reading helps us become more knowledgeable and more intelligent. Also, reading helps us to follow the latest developments of science and technology. Besides, reading gives us information about other cultures and places of the world. When we read, we may find many things that are unfamiliar to us. We would have to use our brain to think about them or do more reading to find out the answers. The more we read, the more we know. What's more, reading is also one of the most important ways to learn a foreign language like English．

    "Reading makes a full man" (Bacon，1597). Books，magazines，newspapers and other kinds of materials can help us to know more about the outside world and perfect us. So it is necessary for us to spend time on reading every day．

    Have you been told you have penicillin allergy? Did your parents tell you that you had a reaction as an infant or child, so you should never take it again? Has it been so long since you had a reaction to penicillin that you don't remember what happened? If you fit any of these descriptions or are just not sure if you have penicillin allergy, there's good news for you: Chances are, you probably don't have it.

    Between 10 to 20 percent of Americans believe they have a penicillin allergy, but a recent study at Mayo Clinic found that only 10 percent of those people are truly penicillin allergic. In other words, 9 out of 10 people who think they have penicillin allergy are avoiding it for no reason. Even in people with documented allergy to penicillin, only about 20 percent are still allergic 10 years after their initial allergic reaction. It's not necessarily a permanent condition.

    Why is this important? Aren't there many other antibiotics you can use if you have penicillin allergy? Penicillin has been around since 1928. Penicillin and its related medicines include amoxicillin, methicillin and amoxicillin-clavulnate. These medicines are highly effective treatments for many bacterial infections, such as strep throat and ear infections. Of course, there are alternative antibiotics, but these are often much more expensive and carry a higher risk of side effects. Typically, these alternative antibiotics are broad-spectrum, meaning they fight many types of bacteria, both good and bad. That can lead to development of drug-resistant bacteria, or deadly “superbugs”. This increases the risk for all of us in the future of not having an effective antibiotic to treat our infection.

    How do you find out if you have penicillin allergy? Board-certified allergists can test you. First, the allergist will get a history from you about your possible allergy. Typical questions include: How long ago did you have the reaction? What type of reaction occurred, and how soon after you took the penicillin did the reaction appear? The testing is done on the forearm by pricking the skin with a needle. If the results are negative and there is no reaction, penicillin will be injected in the skin. These tests are not painful, and results are available in 15 minutes. A positive reaction may lead to some swelling and itching where the test was placed, which usually goes away within an hour.

    In very rare cases, an allergic reaction occurs. This can include hives, swelling, wheezing and/or difficulty breathing. The allergist is trained to treat this rare condition quickly if it happens. If all skin testing is negative, you may be given an oral dose of penicillin in the office. The oral drug challenge is used to verify that you don't have penicillin allergy. Usually, you'll be observed in the office for 30 minutes to make sure you have no problems.

    If you find out you don't have a penicillin allergy, notify your physicians that it's now safe for you to take penicillin. They can take “penicillin allergy” off your chart for good!

    A new technology is going to ripe, one that could transform our daily lives, help to form new industries, even remove world economic powers from their present positions. Unlike the wave of industrialization that began in the West and spread later to the rest of the world, the new developments are taking place in research labs all over the globe—and Asians are in the forefront. Physicists are creating a new class of materials that display an amazing property unforeseen even two years ago—superconductivity (超导体技术).

    Used today only in specialized equipment, super conductors have the potential to radically change most of the electrical and electronic appliances found in the home, making them smaller, more powerful and efficient. They could free our cities of pollution by replacing petrol and diesel (柴油) vehicles with electric cars, and cut the cost of electricity. The new materials do something that even the best of conductors such as copper and silver cannot—they do away with all electrical resistance. The significances for energy storage are great.

    The technology is in its early stage, still accessible to countries that decide to invest brains and money. For 75 years it had remained little more than a scientific curiosity with limited practical use because the phenomenon occurred only at extremely low temperatures. It was first observed in 1911 by a Dutch scientist named Heike Kamerlingh Onnes, who cooled mercury (水银) to temperatures below -269℃ with liquid helium (氦). Then in January last year, two IBM scientists, K. Alex Muller and J. George Bednorz, found a metal oxide ceramic (氧化陶瓷) that superconducted at -243℃. Their report went largely unnoticed until last December, when it was confirmed at a scientific meeting in Boston. Today Japan, India, China and other Asian countries all have their share of experts who spend their days and nights in labs, acting as midwives (助产士) to a new technology.

    Dave Merry and his tools have been through a lot together. The tools helped Dave, now 80, repair his home in St. Paul, Minnesota, where he and his wife, Annette Merry, lived for 46 years and raised three children. The table saw, the jointer plane, the drill press, and the dozens of other power and hand tools had pride of place in his carefully organized workshop. "I had a whole setup, and it was beautiful," says Dave, a retired engineer.

    But then Annette experienced a stroke (中风) that left her relying on a walker to get around, and the Merrys decided to move into assisted living. Dave's workshop was obviously a minor consideration given Annette's condition, but the family knew that giving it up, on top of everything else, would hurt.

    It was the Merrys' daughter who came up with a possible solution. She'd heard about some people who were setting up a tool library—a nonprofit facility that would lend out tools just as a regular library lends books. Might Dad be interested in donating his?

    "I said yes," Dave says.

    The people creating the St. Paul Tool Library were thrilled. They had expected it would take a year to collect enough tools to make their facility fully functional. Instead it took one day: the day Dave donated his.

    The library's founders drove over to the Merrys' house and picked everything up themselves. The library is housed in the basement of the American Can Factory. Members pay an annual fee (from $20 to $120) for unlimited tool use and a varying number of visits to the workshop. And they get an extra benefit: Dave Merry. "Almost every time we're open, Dave's here," says one of the founders, Peter Hoh. "It means a lot to me to be able to go and use my tools," Dave says. "But it means just as much to help DIYers use the tools properly."

    As Hoh puts it, "This is his workshop now."

Welcome to Reading Museum's Hands­on Learning Service

    During the past 100 years, Reading Museum has always been offering learning opportunities to schools, and we hope to continue this tradition for the next 100 years with your support.

    Victorian Schoolroom

    The session takes place in a grand reconstruction of a schoolroom in a late nineteenth century Board School. The children will experience a wide range of Victorian style lessons and use slate boards and dip pens. The session leader will play the role of a Victorian teacher but will come out of the role during the session to comfort the children. We provide costume for all children.

    Victorian Toys

    Our Victorian nanny delivers this interesting session. The nanny will help children to explore the differences between rich and poor children's toys from the past. During the session the children have the opportunity to make a toy to take home.

    Victorian Christmas

    In a specially decorated room the children will find out how the Victorians introduced many of our Christmas customs. They will make a simple card or present to take home.

    For up­to­date prices and session details, please visit our website www.. Reading museum, org. For all session bookings please phone us on 01189373400. Reservation at least 4 weeks in advance is advised. Please be ready to tell us when you wish to come, the session(s) you wish to book and the year group of pupils. Our sessions take place between 10:00 and 12: 00 or 12: 30 and 14: 30. The maximum group size is 35 pupils. We recommend that you bring 5 adults for each group.

    I had the meanest mother in the whole world. While other kids ate candy for breakfast, I had to have porridge, eggs or toast. When others had Coke and candy for lunch, I had to eat a sandwich. But at least I wasn't alone when I was sad. My sister and two brothers had the same mean mother as I did.

    My mother preferred to know where we were at all times. She had to know who our friends were and where we were going. We had to clean clothes and take a bath every day. The other kids got to wear the same clothes for days. We could not lie in bed "sick" in order to miss school.

    The worst is yet to come. We had to be in bed by nine each night and get up at eight the next morning. We couldn't sleep till noon like our friends. So while they slept, my mother was brave to break the Child Labour Laws. She made us work. We had to wash dishes, make beds, and learn to cook and all kinds of things at home. I believe she lay awake thinking up all things for us to do.

    My mother was a complete failure as a mother. Two of her children received higher education. None of us have ever been taken away by the police or divorced (离婚). She forced us to grow up into educated and honest adults. I am now trying to raise my three children this way. I am filled with pride when my children call me "mean". Why? Because now I thank God every day for giving me the meanest mother in the world.
