You don’t wash long enough

A study from Michigan State University study published in the Journal of Environmental Health found that 95 percent of people don’t wash hands long enough to effectively kill germs—that’s 20 seconds of scrubbing with soap and water, according to the Centers for Disease Control and Prevention.

You don’t dry thoroughly

Leaving the restroom with still-damp hands can make, it easier to pick up germ a microbes from the next surface you touch. If you have the choice of paper towels or air blowers, choose the paper towels. In a review of handwashing studies dating back to the 1970s, researchers concluded that paper towels are superior to driers at getting hands properly dry without spattering germs or drying out skin.

You wash only after using the bathroom

Anytime you touch a public surface — elevator buttons, a doorknob, the ATM, or a subway pole — you’re at risk for picking up germs or bacteria.

Electronic book publishing has many of the same risks and opportunities as electronic music publishing. By delivering text directly to the reader's computer screen, the e-book could cut down costs, and allow creators to deal directly with their audience, bypassing traditional publishers and traders. But it also raises the possibility of mass piracy(盗版). Phil Rance, founder and managing director of Online Originals, a London-based e-book publisher, sums it up,“No one wants Napster to happen to books.”

Indeed, the most popular MP3 may have put the frighteners on an industry that generally operates some way behind the “bleeding edge”. The Meta Group, a leading US-based market researcher, says publishers are far too concerned about protecting their rights,“ We believe all the recent legal control over Napster is like putting a finger in a river that is already overflowing. Publishers need to deal with reality and come up with new ways to develop wide electronic distribution, asking the question, ‘How can we change the certainty of wide distribution to our advantage?’ ”

At the moment, most publishers would like to limit the use of e-books to the person who bought them, or to the computer used to download them. If that can be done, e-books become just an extra income stream in a publishing industry that would continue to operate the way it does today, according to Terry Robinson, business manager for the digital rights aspect, “you've cracked the market,” he says.

Robert Nichols, Books Director at BOL agrees, “Rights management is absolutely important. Publishers just say that, ‘until copyright is secure, we're not going to talk’. ”

【小题2】. We recommend a 50/10 split: 50 minutes studying, 10 minutes of anything else. On your break, exercise, or sing, or dance, or sit still. You pick. Then get back to work. Setting a timer will help you find the rhythm (节奏).

Whether your teacher gave you a study guide or not, you need to make your own to cram for an exam. This is undoubtedly the best method to study for an exam. After just making the guide by yourself, 80% of your work will be done. 【小题5】. Only you have to be able to read it.
